Eight years ago, a devastating plague ravaged the capital. Han Changsong, the Deputy Director of the Imperial Medical Academy, was falsely accused of treason over a single prescription. The Emperor ordered the execution of the Han family to the third generation, the razing of their ancestral hall, and the burning of their medical texts to extinguish their lineage. Amidst the chaos, young Han Yunling was nearly buried alive but was rescued by a mysterious savior.

Now grown into a skilled physician, Han Yunling learns that her brother (and last male heir of the Han family), Han Mo, is reportedly being held in the dungeons of the Jinglan capital and is gravely ill. Refusing to believe her uncle's claim that the boy is dead, she orchestrates a plan to reach the capital by disguising herself as a bride for the Jinglan Special Envoy, Zhao Gao.

At the border's Tianlang Pass, war looms as the Changmo general, Gan Yi, challenges General Xiao Chi, known as the "God of Slaughter." Despite suffering from a chronic ailment, Xiao Chi defeats Gan Yi in a duel. Gan Yi retreats, claiming he does not wish to win against an ill opponent or harm civilians. Before Gan Yi leaves, Xiao Chi warns him to tell the Changmo Emperor to cherish the upcoming marriage alliance to ensure lasting peace.

Meanwhile, the Jinglan Minister of Revenue, Fei Zheng, suspects the alliance is a ruse and hastens his journey to the pass. In the envoy's residence, the corrupt Zhao Gao is eager to "inspect" his new bride. Captivated by Yunling's beauty, he attempts to force himself on her before the ceremony.

Thinking quickly, Yunling invents a Changmo legend, warning him that any man who has intimate contact with a bride before the wedding rites will be cursed with divine retribution and misfortune. Terrified for his life, Zhao Gao restrains himself and proceeds with the formal rites. The festivities are interrupted by Xiao Chi, who arrives to arrest Zhao Gao for embezzling 800,000 taels of military funds.

Zhao Gao attempts to invoke the influence of his uncle, Wang Ruhai, but the disciplined Xiao Chi has him dragged away. When Xiao Chi lifts the bride's veil, he immediately recognizes her as his childhood playmate. He remembers a time when she stayed by his side when he nearly drowned, even though she couldn't swim. However, he does not reveal his recognition immediately, choosing to be cautious.

Yunling hides her identity, claiming she was a traveler saved by Zhao Gao in the desert. To secure her stay at the General's residence and continue her search for Han Mo, she demonstrates her medical prowess by identifying the hidden ailments of the General and his lieutenant, Xu Chengfeng. She notes Xiao Chi’s lifelong physical weakness and accurately diagnoses Chengfeng with a persistent case of constipation. Intrigued, Xiao Chi allows her to stay under his observation.

While Xiao Chi reminisces about their past, Yunling works to earn his trust. She provides Chengfeng with a pill for his condition and prepares a prescription for the General. During an acupuncture session the following day, Xiao Chi tests her by asking if she would save a child who wanted to die. Yunling denies her past but confesses a deep desire to see the prosperity of the capital.

Xiao Chi promises that once the wars are over, he will take her there himself. Realizing that Tianlang Pass is heavily fortified and requires a specific token to exit, Yunling attempts to slip away at night. She is intercepted by patrolling guards but lies her way out of trouble by claiming she is searching for herbs for the General.

She learns from her contact, Ms. Wu, that as a Special Envoy, Zhao Gao must possess a unique token that allows passage. Suddenly, a massive fire breaks out at the envoy’s residence. After investigating the scene, Xiao Chi realizes the arson was professionally executed by someone within their own ranks, suggesting a conspiracy. Taking advantage of the chaos, Yunling heads to the prison. She encounters a jailer whose son she had previously saved from death at the city gates.

Using the pretext of delivering a new prescription for the boy, she gains entry to the cells. Yunling finds Zhao Gao and questions him about the token. The cunning official realizes she needs it to escape and demands that she break him out of prison in exchange for the Envoy's token. Just as they strike a deal, Xiao Chi arrives at the dungeon and finds Yunling standing before the prisoner's cell.

Han Yunling enters the prison to seek out Zhao Gao, but she is quickly intercepted by General Xiao Chi. Suspicious of her motives, Xiao Chi demands to know how she gained entry, even threatening the jailer, Huang Jian. Yunling hurriedly explains that she snuck in by herself after begging Huang Jian for a favor, as she had previously saved his son’s life. Xiao Chi remains unconvinced and suspects she still intends to marry Zhao Gao.

To find the truth, he questions Zhao Gao directly. Facing the threat of having his crimes reported to the Emperor, Zhao Gao reveals that Yunling was looking for his special envoy token to travel to the capital. Xiao Chi grows increasingly wary, fearing that Yunling might be a Changmo spy whose presence in the capital could endanger the Emperor. Meanwhile, Fei Zheng, the Minister of Revenue, arrives at an inn near the border.

The innkeeper, Tang Chaoxue, is fascinated to meet someone from the prosperous capital and invites him to share a drink. As they talk, Fei Zheng inquires about General Xiao Chi's reputation at Tianlang Pass. Tang Chaoxue speaks of the General with great admiration, noting that he is the man every woman in the city dreams of marrying.

Back at the prison, Xiao Chi takes Yunling to a dark cell filled with torture devices, hoping to frighten her into revealing her true identity. Yunling remains steadfast, insisting she is only looking for her younger brother. When she finally reveals her name is Han Yunling, Xiao Chi feels a flicker of sympathy and offers to have her escorted safely back to Changmo. However, Yunling refuses to leave without finishing his treatment.

She uses a silver needle to strike a pressure point, paralyzing him, and then ties him up to proceed with the procedure. She explains that the cold poison has accumulated in his spleen and kidneys, leaving him with a pale complexion and cold limbs; without her help, he will not survive. Despite the treatment leaving him physically drained, Xiao Chi receives news that his patrol squad is engaged in a skirmish with Changmo forces.

He insists on going to the city gate tower to oversee the defense. Concerned about his condition, Yunling follows him to the camp, determined not to let her medical efforts go to waste. On the battlefield, several soldiers are wounded by specialized Changmo caltrops. When a scout suggests using opium to dull the agonizing pain, Yunling intervenes, warning that it is far too addictive.

She treats the wounded Jinglan soldiers herself, proving that her compassion as a healer transcends national boundaries. This act deeply moves Xiao Chi, and he finds himself recalling a childhood memory of a young girl bandaging his wounds. Later, while walking through the city streets, Yunling is drawn to a street performance where a magician pulls her into a cabinet.

The sudden darkness triggers a suppressed trauma from her childhood when she was nearly buried alive, and she begins to scream in terror. When she fails to emerge from the cabinet, Xiao Chi realizes something is wrong and confronts the performers. The men panic and flee, but Xiao Chi pursues them and intercepts a group carrying a suspicious box. He finds Yunling unconscious inside and rescues her.

As she regains consciousness, she clings to him tightly, seeking comfort from the fright. Xiao Chi later sends a jar of wine to Yunling to help settle her nerves, but she ends up drinking until she is completely intoxicated. She wanders through the General's Mansion, acting out and loudly demanding that Xiao Chi take her to the capital as he promised.

Fei Zheng happens to arrive at that moment and, seeing the chaotic scene, jokingly accuses his cousin of kidnapping an innocent woman. In the capital city of Jinglan, Emperor Liu Chu expresses his deep dissatisfaction with the proposed marriage alliance with Changmo. However, his core ministers, Wang Ruhai, Li Shichang, and Zhang Ruizhong, urge him to honor the late Emperor's wishes. The Eldest Princess, Liu Xie, arrives at the court to offer her perspective.

She points out that the Emperor has not yet married or established an Empress. She suggests that bringing a Changmo princess into the palace now could complicate the royal bloodline and proposes the alliance be postponed until after the Emperor’s own grand wedding. The ministers are forced to accept her suggestion. Back at Tianlang Pass, Fei Zheng observes the drunken Yunling and notices that Xiao Chi’s health has significantly improved under her care.

He notes that the two of them seem like a well-matched pair and takes it upon himself to decide that Yunling should stay at the mansion to continue the General's treatment. He assures Xiao Chi that keeping her there will not be seen as colluding with the enemy. Though Xiao Chi is still conflicted about her identity, the intervention of his cousin allows the situation to settle for the time being.

Late at night, Emperor Liu Chu sat in the palace courtyard, overwhelmed by the weight of his crown. He confessed to his elder sister, the Eldest Princess Liu Xie, that he felt inadequate as a ruler, lacking the decisiveness their father once possessed. He expressed frustration over the veteran officials—Zhang, Wang, and Li—who held deep roots in the administration and seemed impossible to control.

Liu Xie comforted him, promising her unwavering support to help him restore the glory of the Liu family. As they looked at the moon, they shared a bittersweet moment reminiscing about their childhood and the "Second Brother" who had since become an adversary. The next morning at the General’s Mansion, Han Yunling woke up to find herself in the same bed as Xiao Chi. Their mutual shock led to a chorus of screams, bringing Fei Zheng running to the room.

Dazed and suffering from a temporary memory lapse, Han Yunling barely recognized Fei Zheng. He reminded her that she was staying in the mansion to treat the General's chronic illness in exchange for safe passage to the capital. Soon after, Imperial Physician Li arrived to observe her skills. After checking Xiao Chi’s pulse, Li noted a marked improvement, describing a warm current flowing through the General’s body.

However, he warned that a rare Snow Lotus was required for a permanent cure. Physician Li was struck by Han Yunling’s medical style, noting its resemblance to the disgraced former official Han Changsong. To avoid suspicion, Han Yunling claimed she was merely self-taught. The arrival of the marriage alliance procession brought Princess Jiang Wanyu of Changmo, known as Princess Heshan, to the mansion.

Han Yunling was stunned to see Jin Xi, a female official accompanying the Princess, whom she recognized as a friend who had vanished three years prior. However, Jin Xi acted as if they were total strangers. When Xiao Chi and Fei Zheng sought to verify the Princess’s identity, Jin Xi initially blocked them, claiming the Princess was resting. Eventually, the Princess revealed her face to satisfy the officials' requirements.

To ensure security, Fei Zheng pleaded with Han Yunling to conduct a body search of the newcomers. Xiao Chi privately instructed her to look for hidden weapons like needles, daggers, or poison. During the search, Han Yunling deliberately bypassed the Princess out of respect but carefully inspected Jin Xi. While she reported to Xiao Chi that no weapons were found, Xiao Chi remained suspicious.

He noted that Jin Xi had calluses on her hands typical of someone trained in weaponry, not a common maid. He then tasked the "unbeatable drinker" Fei Zheng with hosting a banquet that evening to loosen their guests' tongues and uncover their true motives. Later, Xiao Chi and Han Yunling walked through the snowy market.

They discussed the long conflict between Jinglan and Changmo, with Han Yunling expressing sympathy for the people beyond the border who fought mainly to escape starvation. Their conversation turned personal when Xiao Chi asked if she had ever suffered a head injury. Han Yunling admitted she had been injured as a teenager, which left some lingering effects. During their walk, she took a sip of what she thought was a harmless drink, but it turned out to be alcohol.

She passed out instantly, and Xiao Chi had to carry her back. At the evening banquet, the atmosphere remained guarded. Jin Xi pressed for a departure date to the capital, but Fei Zheng insisted they wait for an imperial decree. To further test Jin Xi, Xiao Chi ordered Chengfeng to perform a sword dance. During the performance, Chengfeng feigned a stumble and lunged toward Jin Xi, but she remained perfectly composed, proving her intense discipline.

A still-dazed Han Yunling intervened, scolding Chengfeng for "bullying" the woman. The tension was briefly interrupted by the arrival of the local innkeeper, Tang Chaoxue, who teased Xiao Chi about his "romantic debts" before being introduced to the officials. The festivities were cut short by the arrival of an urgent imperial messenger.

The Emperor’s decree was clear: Fei Zheng was ordered to lead the marriage alliance procession back to the capital immediately, and General Xiao Chi was commanded to personally escort them without any delay. Xiao Chi solemnly accepted the order, preparing for the long journey back to the heart of the empire.

The morning after the banquet, Han Yunling woke up to find Xiao Chi by her side. Having stayed up all night to watch over her after she became incapacitated from drinking, Xiao Chi was caught staring tenderly at her when she stirred. Flustered, he quickly made his exit. Han Yunling later approached Xiao Chi to discuss the imperial decree ordering them to the capital. Seizing the opportunity, she expressed concern for his chronic illness during the long journey.

However, Xiao Chi insisted his condition was stable and hesitated to ask her to accompany him. Feeling rebuffed, Han Yunling petulantly claimed she would return to Changmo since she was no longer needed, leaving Xiao Chi wounded by the misunderstanding. Just as the group prepared to depart, Princess Jiang Wanyu was struck by a sudden and mysterious ailment. The imperial physician was at a loss, noting that his medicine was proving ineffective.

Xiao Chi had no choice but to seek Han Yunling’s assistance. After examining the Princess, Han Yunling realized the illness was caused by a slow-acting poison intended to delay their journey to the capital. She informed Xiao Chi that the condition required prolonged treatment, effectively securing her place in the traveling party.

When Xiao Chi pushed for her true motive, Han Yunling confessed she was searching for her brother, Han Mo, the last male heir of her family, who was currently held on death row in the capital. Xiao Chi agreed to let her follow as his physician, while leaving Lu Li in charge of defending Tianlang Pass in his absence.

Meanwhile, within the capital, senior officials like Wang Ruhai and Zhang Ruizhong gathered at Lord Li’s residence for a lavish evening of entertainment. Lord Li had purchased several dancers from Changmo, including the lead dancer Yina, whose beauty was considered priceless. While Zhang Ruizhong chose Yina for himself, Lord Li distributed the other dancers among the officials to secure their favor.

These men, old subordinates of the late Emperor, toasted to their continued influence over the young Emperor, Liu Chu, using these foreign beauties as political tools. As the escort party moved toward the outskirts of the capital, they arrived at an inn that Tang Chaoxue had meticulously prepared in advance. Her clear devotion to Xiao Chi made Han Yunling feel a sharp pang of jealousy.

That night, after Han Yunling finished treating the Princess, she turned her attention to Xiao Chi. She informed him that his treatment now required physical massage to accompany the acupuncture. Xiao Chi, who had never allowed a woman to touch him so closely, was visibly embarrassed. Their session was interrupted by Tang Chaoxue, who brought a bowl of ginseng soup. Seeing Xiao Chi partially undressed with Han Yunling, Tang Chaoxue’s jealousy flared.

To break the tension, Han Yunling drank the soup herself, critiquing its quality and sending a frustrated Tang Chaoxue stomping out of the room. The next morning, Fei Zheng teased Xiao Chi about the "ghostly wailing" heard from his room the night before, referring to the painful massage session. Despite her own physical exhaustion and a sore back, Han Yunling insisted on riding her horse rather than taking the carriage Xiao Chi offered.

Throughout the journey, Han Yunling repeatedly probed Jin Xi about her identity, convinced they shared a past, but Jin Xi remained firm, denying any knowledge of her. As they drew closer to the capital, Jiang Wanyu felt a mix of nerves and curiosity about her future husband, Liu Chu. Late that night, Jin Xi requested a private meeting with Fei Zheng. She produced a Changmo token, revealing that she knew his secret identity as a spy who had been embedded in Jinglan for years, leaving Fei Zheng in utter shock.

Years ago, Fei Zheng stood before the leader of Changmo and swore a solemn blood oath to serve the tribe for life, even while stationed in the kingdom of Jinglan. His childhood friend and fellow trainee, Jin Xi, eventually approached him in the capital and presented a token representing the King of Mo. Now a high-ranking official as the Minister of Revenue, Fei Zheng was reminded of his sleeper status.

Jin Xi informed him that it was time to activate his role to assist in a long-planned scheme for revenge, with his immediate mission being to ensure the safety of the Changmo princess during her marriage alliance. As Xiao Chi and his group traveled through the forests west of the capital, they were intercepted by a band of desperate bandits.

The thieves were quickly overwhelmed by Xiao Chi’s soldiers, and upon realizing they were facing government officials, they begged for mercy. The bandits explained they were actually displaced villagers from Qingshan Village whose land had been forcibly seized by the servants of the powerful official Wang Ruhai to build a tomb for his recently deceased concubine.

Moved by the sight of the elderly and weak hiding in the shadows, Xiao Chi provided them with silver to settle elsewhere and promised to report this injustice to the Emperor. In the capital, Emperor Liu Chu was eager to welcome his childhood friends, Xiao Chi and Fei Zheng. He spent the morning meticulously dressing in his finest robes, intending to meet them personally at the city gates.

However, his plan was blocked by Wang Ruhai and two other senior ministers. They chided the Emperor for neglecting his duties at the Hall of Diligent Governance and argued that it was beneath his dignity to personally receive a "brute soldier." Asserting their authority as the late Emperor’s trusted advisors, they punished Liu Chu by ordering him to remain in the palace and copy the ancestral instructions ten times before he was permitted to see his friends.

While the ministers went to the city gates to receive the group, the Princess of Changmo was settled at a post house. Xiao Chi and Fei Zheng were then summoned to the palace for a formal court session. During the meeting, Liu Chu expressed his deep affection for his friends and proposed transferring Xiao Chi to the capital's defense so he would not have to return to the dangerous border.

This suggestion was immediately met with resistance from the senior ministers, who claimed that replacing a general so abruptly was a grave taboo. Xiao Chi seized the moment to retaliate against the ministers' overbearing behavior. He revealed that he had brought back the Border Special Envoy, Zhao Gao, and openly accused him of embezzling 800,000 taels of military funds and attempting to force a woman into marriage.

When Wang Ruhai tried to defend his nephew, Xiao Chi detailed how the official’s servants had seized land in Qingshan Village, leaving the people destitute. Faced with these direct accusations, Wang Ruhai could only stammer in denial. Seeing his chance to check the power of the old guard, Liu Chu ordered Wang Ruhai to retire to his home while a full investigation was conducted. Later that night, Liu Chu, Xiao Chi, and Fei Zheng gathered for a private celebration.

The Emperor dismissed his attendants so they could drink freely, just as they had done years ago at the manor. Relieved to have finally vented his frustrations against the ministers, Liu Chu rewarded Xiao Chi with a special imperial token that granted him unrestricted access throughout the capital. As the wine flowed, the conversation turned toward Xiao Chi’s future wedding.

When the others joked about the many women at the border who wanted to marry the general, the usually stoic Xiao Chi became flustered and quickly made an excuse to leave. Meanwhile, Han Yunling had left the post house on her own, determined to find the location of the Imperial Prison so she could search for her brother, Han Mo. As she navigated the city streets, she was harassed by a group of scoundrels.

Though she defended herself by throwing chili powder at the men, they eventually cornered her in a dead end. Just as the thugs prepared to attack, Xiao Chi arrived on horseback and rescued her. Liu Chu later visited his elder sister, the Long Princess Liu Xie, to boast about his newfound sense of authority. However, Liu Xie scolded him for recalling a vital border general without consulting her, fearing that Changmo might take advantage of Xiao Chi’s absence.

Despite her concerns, she agreed that Xiao Chi deserved a significant reward. At her suggestion, the Emperor granted Xiao Chi his own former residence—the old prince’s manor—to serve as the general's new home. Although Xiao Chi felt it was inappropriate to live in the Emperor's former quarters, he was forced to accept the decree.

He settled into the manor and invited Fei Zheng to stay in the South Courtyard, while assigning Han Yunling to the East Courtyard, the very rooms where Xiao Chi himself had once lived.

Years ago, young Han Mo sneaked a candied hawthorn, hoping to hide the treat from his strict father. His cousin, Han Yunling, caught him and playfully reminded him to be careful. Their peace was shattered when Han Mo's second uncle returned home covered in blood. In a desperate attempt to save the children, the uncle pushed them over the back wall to escape, but Han Mo fell.

From the ground, the terrified boy witnessed the brutal slaughter of his entire family. In the present, Xiao Chi hurried to the Imperial Prison to investigate the case of Han Mo. He was unsettled to find that the case file was completely blank, containing no record of the crimes. Despite the historian's warnings, Xiao Chi used an imperial token to gain access to the high-security cell.

There, he found Han Mo in a horrific state; the prisoner had been suspended upside down during the day and subjected to relentless whipping for over a decade. Deeply troubled, Xiao Chi brought Han Yunling to the cell late at night for a secret reunion. Han Yunling was devastated to see her cousin on the brink of death. She administered a pill, and Han Mo briefly regained consciousness to recognize her and plead for help.

However, his strength quickly faded, and he appeared to draw his last breath. Believing her brother had died, Han Yunling collapsed in grief. Their mourning was interrupted by the arrival of Steward Shen, the servant of Zhang Ruizhong. Xiao Chi and Han Yunling hid as the arrogant steward entered the cell and dismissed the guards. Believing Han Mo was merely playing dead to avoid pain, the steward continued to whip the motionless body.

Xiao Chi held the trembling Han Yunling close to prevent her from exposing them, while his own heart ached at the desecration of the boy’s body. He began to suspect that Zhang Ruizhong was the architect of the Han family's ruin, as the man had spent a decade keeping Han Mo alive only to torture him. Meanwhile, Wang Ruhai remained under house arrest and grew increasingly desperate.

He sought help from Lord Zhang (Zhang Ruizhong), hoping for an audience with the Emperor. Lord Zhang, privately enjoying Wang’s downfall, feigned a willingness to help and escorted him to the palace. While ostensibly pleading for mercy before Emperor Liu Chu, Lord Zhang subtly suggested that Wang’s crimes deserved harsher treatment.

Seeing the elderly official kneeling in the sweltering heat, the Emperor grew concerned for his health and ordered him to return home, though he refused to rescind the retirement order. On the way back, Lord Zhang deceitfully took credit for the Emperor's leniency, claiming he had pacified the sovereign’s anger. Xiao Chi eventually managed to smuggle Han Mo out of the prison. To Han Yunling’s relief, she discovered her cousin was not dead but in a deep, needle-induced coma.

To save him, she required a catalyst for her medicine. Since no water was available in the wilderness, Xiao Chi insisted on using his own blood as a life-force for the pill, despite his own lingering illness. The strain proved too much, and Xiao Chi lost consciousness shortly after. The following morning, Xiao Chi awoke to find Han Yunling tending to him and Han Mo.

She intended to take her brother back to Changmo once he recovered, but Xiao Chi insisted they stay to uncover the truth behind the blank case files. He decided to take them to his old master, Liu Xiyang, for safety. At the Master’s residence, they were greeted by Liu Xiyang and his daughter, Eighteen.

Though initially grumpy, the Master agreed to care for Han Mo in exchange for the secrets of Han Yunling’s medical preservation technique and a steady supply of the capital's finest wine. In the city, Tang Chaoxue arrived looking for a shop. Although she initially found the prices exorbitant, she immediately paid the lease upon learning the property was located right next to Xiao Chi’s residence and near his garrison, determined to stay close to the General.

Back at the General's manor, Lord Fei arrived early to find that Xiao Chi had been away all night. When Xiao Chi finally returned, Lord Fei escorted him to the West Courtyard. There, they were met by the attendant Jin Xi, who insisted the Princess was still resting from her journey, maintaining the secret of Han Yunling's true identity within the manor walls.

After suffering a severe wound from Liu Chu during their clash, the King of Changmo seethes with a vow to destroy the kingdom of Jinglan to avenge his humiliation. Meng Ling, the Hall Master of Caidie Hall, suggests that because they lack a clear advantage on the battlefield, they should instead dismantle the enemy from within. Pleased with this strategy, the King promises to name Meng Ling as his consort and share his future glory once Jinglan is destroyed.

When his daughter, Princess Jiang Wanyu, arrives to pay her respects, the King manipulates her into believing she is destined for a blissful marriage with Liu Chu. Though the King paints a picture of a perfect life in a grand palace to ensure her cooperation, he secretly views his daughter as nothing more than a political pawn.

Jiang Wanyu, trusting her father completely, begins to fantasize about a happy future with Liu Chu, hoping their union will finally bring peace between their two nations. Meanwhile, in Jinglan, the disgraced Wang Ruhai finds himself humiliated and powerless, lashing out at his attendants in his residence. Elsewhere, Liu Chu and Fei Zheng enjoy a quiet afternoon of fishing.

Upon learning that Fei Zheng and Xiao Chi are now living together in the Xiao residence, Liu Chu decides to sneak out of the palace that night to join them. Unbeknownst to the Emperor, Fei Zheng is intentionally drawing him out of the palace for his own reasons. That evening, Xiao Chi and Han Yunling pass by Tang Chaoxue’s exquisitely decorated shop.

Tang Chaoxue enthusiastically gifts Xiao Chi a jar of precious Nverhong wine, which her father had buried twenty-four years ago on the day she was born. Intrigued by the "strange man" Xiao Chi is visiting, Tang Chaoxue follows him the next day to the mountain retreat of Liu Xiyang. The eccentric Liu Xiyang, who can smell the quality of the wine from afar, is challenged by Tang Chaoxue to guess her age.

He correctly identifies her as twenty-four, explaining that in Jinglan, unmarried women over eighteen wear specific colored hairpins each year, and her violet pin gave her away. Their spirited banter leaves Xiao Chi thinking they are perfectly matched. While Princess Jiang Wanyu anxiously awaits news regarding her wedding, her attendant Jin Xi receives a secret missive from Changmo and quickly destroys it to hide their hidden agenda.

Across the city, Xiao Chi and Xu Chengfeng spend a grueling and fruitless day at the Archives, searching through twenty years of capital case files for the truth behind the Han family massacre. Meanwhile, Han Yunling remains at home, meticulously preparing medicinal pouches for her brother, Han Mo, and gathering silver needles to treat Xiao Chi's lingering ailments.

Later that night, Liu Chu successfully slips out of the palace and joins Xiao Chi and Fei Zheng on a rooftop to reminisce about their youth. Below them in the courtyard, Jiang Wanyu is encouraged by her attendant to make a wish upon the full moon. As she prays for a swift marriage and a long life with the Emperor of Jinglan, Liu Chu loses his footing and tumbles from the roof, landing right in front of her.

Startled, Liu Chu recognizes her as the Princess of Changmo but fabricates a lie, claiming he is merely General Xiao’s elder brother out for some fresh air. When she offers him wine to ease the pain of his fall, he declines and makes a hasty, awkward retreat with Fei Zheng. As dawn approaches, Han Yunling grows increasingly worried about Xiao Chi’s late return.

When he finally arrives at the residence and claims he has been busy all night, she is waiting for him with her prepared silver needles. Despite his weariness, she insists they proceed with his acupuncture treatment immediately, believing the timing is perfect for the medicine to take effect.

The episode begins with a flashback to Jin Xi’s childhood. Born with a kind heart, she could not bring herself to kill a chicken for food. However, Fei Zheng, intent on teaching her the cold reality of survival, forced her to act. He warned her that if the bird did not die by dawn, she would be the one to perish.

Under this brutal pressure, Jin Xi eventually took the life of the animal, a moment that marked the end of her innocence and the beginning of her transformation into a survivor. In the present, Eldest Princess Liu Xie remains deeply suspicious of the Emperor’s frequent visits to the General's Mansion.

Fearing that Liu Chu is being led astray by those with ulterior motives, she orders her guards to monitor the mansion day and night, demanding reports on every person entering or leaving. That night, Jin Xi notices she is being followed by one of the Princess's agents. To protect her secret meeting with Fei Zheng, she kills the spy. When Fei Zheng arrives, he scolds her for her impulsiveness, noting that Jinglan is far more dangerous than Changmo.

He warns her that if her cover is blown, she will be left to suffer the agonizing fate of the Gu poison. Meanwhile, at the palace, Liu Chu is lost in daydreams of the beautiful Princess Jiang Wanyu. When Fei Zheng arrives, Liu Chu attempts to use Xiao Chi’s poor health as an excuse to slip out of the palace and visit the General’s Mansion. However, his plan is thwarted by Liu Xie, who arrives with the treasury ledgers.

She insists that he fulfill his royal duties, reminding him that despite their sibling bond, they are also ruler and subject. By forcing him to review the accounts, she keeps him under her watchful eye for the rest of the night. At the mansion, Jin Xi has prepared snacks and arranged for Jiang Wanyu to enjoy the moonlight, hoping to facilitate another encounter with Liu Chu.

As they wait, Jiang Wanyu reflects on the man who fell from the sky during their previous meeting. Though she claims he lacks the martial valor of her father, the King of Changmo, she admits he is not unpleasant. Jin Xi notices the Princess’s interest and teases her about it, but Jiang Wanyu quickly deflects the conversation. Eventually, as it becomes clear the Emperor will not be coming, Jin Xi escorts the Princess back to rest.

The next day, Han Yunling provides Xiao Chi with a new medicinal pill, using wine as a messenger herb to aid his recovery. Her growing affection for the General is evident in her meticulous care. Simultaneously, Zhang Ruizhong grows anxious upon learning that Xiao Chi is reinvestigating the Han family case. He orders his steward to monitor the General’s every move. Xiao Chi, accompanied by Xu Chengfeng, visits Lord Xue, a senior official he has respected since childhood.

Xiao Chi attempts to probe into the old Han family case, suggesting it might have been a wrongful conviction. However, Lord Xue remains evasive, claiming his memory is failing and advising Xiao Chi that the best way to survive in officialdom is to avoid reopening settled cases. When Jin Xi visits Han Yunling to retrieve medicine for the Princess, her Gu poison suddenly flares up, causing her immense pain.

Han Yunling stabilizes her and reveals that she recognized Jin Xi as the girl she saved years ago. While Han Yunling does not have a guaranteed cure for the poison, she urges Jin Xi to reveal the details of her symptoms so she can attempt to craft an antidote.

Jin Xi remains guarded, claiming her burden is hers alone, but Han Yunling promises to study the condition out of her own medical curiosity, hoping to find a way to help her old friend. Trouble arises in the city when Wang Ruhai’s son, an arrogant bully, harasses a vendor before storming into Tang Chaoxue’s restaurant. He aggressively clears out the patrons and demands the best wine.

When Tang Chaoxue tries to appease him, he insults her and begins to physically harass her. Han Yunling, who had been following the Young Master after witnessing his earlier cruelty, intervenes. She defends Tang Chaoxue and beats the Young Master, identifying herself as General Xiao’s physician. Xiao Chi arrives at the restaurant and witnesses the aftermath of the confrontation.

Seeing the Young Master’s blatant disregard for the law, Xiao Chi begins to suspect that Lord Xue was silenced or coerced because he held the truth about the Han family. He rushes back to Xue’s residence, only to find that the old man has been murdered in broad daylight. The scene is in chaos, and the killers have already fled.

Xiao Chi is now certain that the Han case is part of a larger conspiracy, and he suspects Zhang Ruizhong’s involvement. The Young Master returns home and complains to his father, Wang Ruhai, about the physician who attacked him. Infuriated by the perceived insult to his family name, Wang Ruhai orders his advisor to have Tang Chaoxue’s restaurant shut down. Meanwhile, Zhang Ruizhong’s steward confirms that Lord Xue has been silenced and his family sent away.

They anticipate that Xiao Chi will not stop his investigation and begin preparing a trap for him. Later that night, Jin Xi meets Fei Zheng again. He informs her that the Hall Master has developed a new, more lethal Gu poison and that her symptoms are already progressing. They agree that they must hasten the marriage between Liu Chu and Jiang Wanyu to complete their mission and secure the antidote before time runs out.

Meanwhile, Han Yunling confesses to Xiao Chi that she beat the Young Master, worried that she has caused him trouble. Xiao Chi, who admires her courage, reassures her and promises to protect her in the capital. Elsewhere, Jiang Wanyu gazes at the moon, missing her father but quietly hoping for a happy life in her new home.

Early the next morning, Fei Zheng hurried to the palace to see Liu Chu. Still nursing an injury from falling off the roof, Liu Chu moved cautiously, desperate to hide his pain from his elder sister, Liu Xie. He feared that if she discovered his escapade, he would lose any future chance of leaving the palace.

Fei Zheng saw through the act and teased him, using the opportunity to invite him to join a drinking session with Xiao Chi later that night in the bamboo forest they had planted together years ago. Though eager, Liu Chu lamented that Liu Xie was scheduled to visit him that evening, making an escape impossible. Meanwhile, at the General’s Mansion, Jiang Wanyu was growing restless, longing for the desert sands of Changmo.

Han Yunling, sympathizing with the confined princess, suggested they go out for a walk. As they prepared to leave, Lieutenant Chengfeng tried to intervene, insisting they stay for lunch for the Princess's safety. However, Han Yunling and Jin Xi stood their ground, arguing that staying cooped up would drive anyone mad. Reluctantly, Chengfeng let them go, and the group headed into the bustling streets.

During their outing, they crossed paths with the same three thugs who had previously harassed the Princess. Jin Xi, ever vigilant, noticed them leering and decided to lead the troublemakers away. She lured them into a back alley, ensuring they wouldn't bother the Princess and Han Yunling further while she dealt with them. While exploring the stalls, Jiang Wanyu and Han Yunling carefully selected a beautiful hairpin for Jin Xi.

When they presented it to her later, Jin Xi was deeply moved; having grown up alone, she had rarely experienced such genuine kindness. That night, Xiao Chi confronted Han Yunling about taking the Princess out without permission. He spoke sternly, reminding her of the grave consequences if anything happened to the Princess. Realizing her oversight, Han Yunling apologized with sincere regret. Softened by her contrition, Xiao Chi’s anger faded.

Han Yunling then presented him with a sachet filled with medicinal herbs, insisting he keep it with him for protection against illness. In the quiet of the bamboo forest, Fei Zheng and Xiao Chi shared wine and reminisced about their youth. Without Liu Chu, the gathering felt incomplete, and the two friends plotted to sneak the Emperor out for a proper reunion in the future.

Fei Zheng also hinted at finding a way to keep Han Yunling in the capital permanently by providing her with a home, noticing Xiao Chi’s growing feelings for her. The next day, Xiao Chi visited the chief minister, Zhang Ruizhong, to probe for information regarding the Han family case. He mentioned the murder of Judge Xue, who had presided over the case years ago. Zhang Ruizhong acted shocked but remained composed, recalling a devastating plague that once gripped the capital.

He claimed the Han family was executed for administering the wrong medicine, resulting in many deaths, and coldly insisted they had received what they deserved. Back at the mansion, the Sand Sacrifice Festival arrived. Feeling homesick, Jiang Wanyu performed a traditional dance from Changmo under the moonlight. Liu Chu, who had managed to slip away again, stood mesmerized by her grace.

When she noticed him, Jiang Wanyu blushed, but Liu Chu encouraged her to continue, calling her a fairy descended to earth. As they shared a drink, Jiang Wanyu spoke of her admiration for the Emperor of Jinglan, believing him to be a wise and compassionate ruler. Liu Chu, hiding his true identity, listened with warmth. When Jiang Wanyu asked if he had a sweetheart, Liu Chu looked at her deeply, hinting that he had already found her.

Realizing the intimacy of the moment, Jiang Wanyu made an excuse to leave, but Liu Chu’s affection for her only deepened. Nearby, Jin Xi and Fei Zheng watched from afar. Jin Xi, feeling the pressure of her mission, suggested killing Liu Chu immediately. Fei Zheng rejected the idea, reminding her that her primary duty was to protect the Princess and ensure the marriage alliance.

He confessed that Liu Chu and Xiao Chi were his brothers, and if a day ever came when they had to die, he wanted to be the one to see them off personally. The following morning, Han Yunling stood on the bridge where she had once saved a young Xiao Chi, lost in thought. Xiao Chi approached, hoping she was remembering their past, but she remained silent. Meanwhile, Liu Chu consulted with Fei Zheng about the upcoming wedding.

Fei Zheng presented auspicious dates and urged that the ceremony be held as soon as possible to avoid any suspicion from Changmo. Liu Chu agreed, setting the date for the following month. When the news reached the King of Changmo, he was overjoyed, believing his plan to annex Jinglan was nearing a successful conclusion.

A terrifying and mysterious epidemic breaks out in Huangpi Village on the outskirts of the capital, leaving dozens infected and the court in a state of panic. During an imperial meeting, Fei Zheng proposes a plan to send physicians, establish a quarantine zone, and allocate food and funds to prevent the disease from spreading.

However, officials like Li Shichang oppose the plan, fearing the physicians might bring the plague back to the capital and questioning the use of national funds for commoners. Zhang Ruizhong suggests a ruthless "decisive measure": abandoning Huangpi Village entirely. Xiao Chi is outraged, arguing that while he kills enemies in war, the villagers are innocent subjects.

Reminding the court of the tragedy eight years ago, Xiao Chi wins the support of Emperor Liu Chu, who orders him and Han Yunling to lead the relief mission, promising they will be honored as key ministers if they succeed. Xiao Chi is deeply concerned for Han Yunling’s safety, knowing the mission is a life-or-death gamble. However, Han Yunling is resolute, viewing the healing of the sick as her duty.

With an imperial decree granting her authority over the Imperial Medical Academy's supplies, she prepares medicine for her brother, Mo, and promises to save him once she returns. As they prepare to depart, Zhang Ruizhong sends a coffin as a "gift," mockingly wishing Xiao Chi a promotion and wealth—a cruel omen suggesting the General will not return alive. Ignoring the provocation, Xiao Chi sets off for the village.

The scene at Huangpi Village is devastating, with the death toll rising and villagers feeling abandoned by the court. The arrival of General Xiao provides a flicker of hope, and the people begin to cooperate. Physician Chen Yuan informs them that the symptoms are strikingly similar to the "Death Plague," a highly infectious disease with no known cure. Using her uncle's ancient medical notes, Han Yunling organizes a specialized treatment area to isolate the infected.

Orphaned sisters Cuizhi and Cuimiao, who lost their parents to the disease, volunteer to assist in the quarantine zone, inspiring other young men to join the effort. While Han Yunling works tirelessly, she makes a shocking discovery: the pulse of the infected Cuizhi shows clear signs of poisoning. It becomes evident that the "epidemic" is not a natural disaster but a deliberate act of human malice.

Meanwhile, a new crisis emerges as Zhang Ruizhong’s guards blockade the village under "orders from above," refusing to let anyone leave for herbs. Xiao Chi is nearly forced to use violence to break the siege until Fei Zheng arrives with an imperial decree and a shipment of supplies—including Atractylodes to fumigate the village—sent by the Eldest Princess Liu Xie. To find a cure, Han Yunling needs to test a potent but dangerous remedy.

Fei Zheng offers to return to the capital to find a death row inmate for testing, warning Xiao Chi against reckless actions. However, with time running out and the villagers dying, Han Yunling contemplates testing the medicine on herself. Xiao Chi intervenes and, in a desperate act of sacrifice, consumes the toxic blood taken from Cuizhi's fingertip to infect himself. He argues that his own body is already compromised and that Han Yunling is too important to risk.

The poison takes hold quickly. That night, Xiao Chi collapses, vomiting black blood and burning with a high fever. Han Yunling is struck with urgency, realizing that the remedy is struggling against his naturally weak constitution. Seeing that he may not survive the night, she decides to use a risky acupuncture method to save him, instructing Physician Chen Yuan to help undress the General so she can begin the treatment immediately.

With Xiao Chi hovering on the brink of death after risking his life to test the remedy, Han Yunling focused all her skill on performing the legendary Tai Xuan Acupuncture. Physician Chen, who had practiced medicine for sixty years, watched in awe; he had only ever read of this long-lost technique in ancient medical texts and felt his lifelong pursuit of medicine had reached its pinnacle upon seeing it performed.

Han Yunling remained modest, admitting she had only mastered the basics. However, through Xiao Chi’s reaction to the trial, she unlocked the true nature of the affliction: it was not a contagious plague, but a deliberate poisoning that caused the blood to congeal into a fragrant powder rather than a foul liquid. She explained that the remedy worked on the principle of fighting poison with poison, but required the stimulation of acupuncture to expel the toxins.

Leaving Xiao Chi in Physician Chen’s care for the night, Han Yunling tirelessly spent the following hours treating the suffering villagers. By dawn, the villagers had begun to recover. Filled with gratitude, they gathered to thank Han Yunling for saving their lives. When Xiao Chi finally regained consciousness and learned that Han Yunling had not slept for days to ensure everyone's safety, he rushed to her.

Seeing her standing safely among the recovered villagers, he was overcome with emotion and pulled her into a tight embrace. In the imperial capital, Zhang Ruizhong and Li Shichang continued to pressure Emperor Liu Chu, heartlessly suggesting that the entire village be eliminated to prevent the "Death Plague" from reaching the city. They argued that any risk to the capital would ruin the Emperor's legacy.

However, Fei Zheng stood his ground, reminding the court that the people are the foundation of the empire. Their debate was interrupted by a report confirming the village had been cured. Delighted, Liu Chu praised Xiao Chi’s heroism and pointedly ordered a reluctant Zhang Ruizhong to personally welcome the general back to the palace. Before leaving the village, the locals held a banquet to honor their saviors.

Under the moonlight, Xiao Chi and Han Yunling shared a quiet moment, reflecting on the "ray of light" that guides people through darkness. Their peace was brief, as Fei Zheng soon arrived to escort them back to the capital, noting that the Emperor was eagerly waiting. Meanwhile, the Emperor’s habit of sneaking out of the palace had not escaped the notice of his elder sister, the Eldest Princess Liu Xie.

Curious about the woman who had captured her brother's attention, Liu Xie visited the General's Mansion to meet Jiang Wanyu. While Liu Xie maintained a graceful exterior, even gifting Jiang Wanyu a precious hairpin belonging to her late mother, her eyes betrayed a hidden disdain for the girl's simplicity.

The naive Jiang Wanyu, unaware of the princess’s true feelings, eagerly asked about Liu Chu’s preferences, even expressing a desire to learn the art of ear cleaning to please him once they were married. Behind the scenes, Zhang Ruizhong revealed his true role in the crisis while playing a game of chess. It was he who had orchestrated the "plague" through poisoning.

Unfazed by the villagers' recovery, he plotted to claim that the illness had relapsed, instructing his steward to act ruthlessly to ensure the "Death Plague" appeared to return. When Xiao Chi, Han Yunling, and Fei Zheng reached the capital gates, they found their path blocked. Zhang Ruizhong, citing the safety of the citizens, commanded that they be quarantined in the General's Mansion for observation before being allowed to see the Emperor.

Now confined to the East Courtyard, Han Yunling felt a deep sense of injustice, being treated like a prisoner after risking her life to save others. Across the estate, Fei Zheng confronted Jin Xi, whose surprised reaction to the villagers' recovery made him suspect she knew more about the poisoning than she let on. Jin Xi denied any involvement, claiming she never left the princess's side.

As the quarantine continued, Jiang Wanyu gossiped with Jin Xi, wondering if being locked together would spark a romance between the General and the Physician. In the palace, Liu Xie practiced her formidable martial arts, her skills rivaling any soldier. When Liu Chu came to discuss the marriage alliance, she offered no resistance. They settled on a date: the tenth day of the next month. Liu Xie smiled, calling it the best day for her brother to marry the woman he loved, though her true intentions remained veiled.

Xiao Chi and Han Yunling remained confined within a small courtyard, but Xiao Chi appeared perfectly at ease, relishing the rare stillness of being alone with her. He prepared a meal of grilled skewers to share, but the peaceful atmosphere shifted when Han Yunling accidentally took a drink of wine. The alcohol went straight to her head, and she began to act out, jumping around and rambling incoherently.

She even playfully pretended to be a soldier on horseback, exhausting Xiao Chi as he tried to manage her antics. Eventually, her strength faded, and she fell asleep in his arms. As he watched over her, Xiao Chi gently brushed her hair aside with tenderness, confessing that this secluded life was exactly what he had always dreamed of. The following morning, Han Yunling woke up with a painful, stiff neck from her drunken slumber.

Xiao Chi had been busy in the kitchen trying to make amends with a hot meal, but his culinary skills were severely lacking. He presented her with what was supposed to be congee, but he had cooked it so long it had turned into a hard rice crust. When he tried to cook other dishes, the results were equally unappetizing. Han Yunling eventually decided to take over the cooking herself to avoid being "poisoned" or starved.

Xiao Chi tried to assist by chopping vegetables, but in his eagerness, he used far too much strength and snapped the cutting board in two. Despite the kitchen chaos, they eventually sat down to a simple home-cooked meal, which Xiao Chi found far more satisfying than military rations. Meanwhile, at the imperial court, Fei Zheng spoke up on behalf of Xiao Chi and Han Yunling.

He argued that it was unjust to keep such meritorious heroes under house arrest after they had successfully cured the people of Huangpi Village. However, Zhang Ruizhong and Wang Ruhai countered his pleas, insisting the confinement was a necessary safety precaution to ensure the epidemic did not reach the capital. Liu Chu, clearly irritated by the political posturing, ended the debate by decreeing that Xiao Chi and Han Yunling would be released to attend his upcoming wedding.

He also took the opportunity to reprimand Wang Ruhai, ordering him to return to his manor and reflect on his past failures rather than involving himself in court affairs. As the wedding day approached, an imperial decree officially ended the month-long quarantine, summoning Xiao Chi and Han Yunling to the palace to receive their rewards. Han Yunling wasted no time in visiting Jiang Wanyu.

While she complained to the princess about how boring it had been to stay with the "annoying" Xiao Chi, she took a moment to speak privately with Jin Xi. Han Yunling handed over a special medicine she had formulated, hoping it would help treat the underlying condition Jin Xi had been struggling with. Deep within the palace, Liu Xie reflected on the "Way of the Emperor" her father had taught her.

Though she had mastered the art of governance and the balance of power, she harbored a growing resentment over the fact that, as a woman, she could never inherit the throne. Watching her younger brother grow into his role, she realized he might not remain under her influence forever once he was married.

She began to formulate a plan to secure her grip on the empire by focusing on the next generation, intending to control any children born to the royal couple to ensure the long-term stability of the Liu family's power. The wedding of Liu Chu and Jiang Wanyu was a grand, festive occasion signaling a new era of peace between the nations of Jinglan and Changmo.

As the two countries agreed to cease hostilities and open their borders for trade, the court celebrated the hope of eternal prosperity. Liu Xie watched from the sidelines, noting that her brother was finally beginning to embody the presence of a true sovereign. While the palace was filled with music and joy, the significance of the union was felt by all, marking a historic shift in the relationship between the two long-warring states.

Inside the bridal chamber, Jiang Wanyu found herself overwhelmed by the complexity of the ceremony. Exhausted and hungry, she abandoned the strict etiquette her father had taught her and began snacking on the pastries left in the room. When Liu Chu arrived, she hurriedly replaced her veil. Following tradition, Liu Chu used a ceremonial weighing rod to lift the red cloth.

Jiang Wanyu was stunned to discover that the man she had previously known only as "Big Brother" was actually the Emperor himself. Liu Chu explained that he, Xiao Chi, and Fei Zheng were sworn brothers, and as the eldest of the three, he had been telling her the truth about his status all along. The wedding night was soon interrupted when Zhang Ruizhong arrived with urgent news regarding a diplomatic envoy being sent from Changmo.

Despite the late hour, Liu Chu recognized the weight of the matter and agreed to meet with his ministers in the Imperial Study. While the Emperor was occupied with policy, Jin Xi took advantage of the distraction to move through the palace grounds. She carefully mapped out the locations of the Imperial Garden, the kitchens, and the royal bedchambers. She was nearly caught by a patrolling commander, but Fei Zheng appeared and managed to deflect the guard's suspicion, allowing her to slip back into the shadows unnoticed.

Under the cover of night, Jin Xi infiltrates the heavily guarded palace but is nearly discovered by patrolling guards. Fei Zheng, the newly appointed Minister of Rites, timely intervenes to save her. He dismisses the guards’ suspicions by claiming he is supervising the complex royal etiquette following the Emperor's wedding. Once alone, Jin Xi reveals she has secured the palace layout but still needs the defense maps for the capital and the strategic Tianlang Pass.

She informs Fei Zheng that the Hall Master of Caidie Hall is arriving with the marriage envoy to oversee the next phase of their mission. Having spent her wedding night alone, Jiang Wanyu feels a sense of disappointment, though she is somewhat comforted by the gifts Liu Chu sends the next morning. When Liu Chu finally visits her late at night, Jin Xi discreetly withdraws.

However, Liu Chu finds the maid’s gaze strangely familiar, reminding him of the look in Fei Zheng’s eyes. Just as the couple prepares for an intimate moment, Lord Zhang Ruizhong interrupts yet again. Liu Chu is forced to leave, promising to return shortly, though Wanyu remains skeptical. Lord Zhang brings a vast amount of wine, explaining it is the anniversary of his first military campaign alongside the late Emperor.

Liu Chu, wanting to honor the old minister’s loyalty, agrees to drink with him. During their conversation, Zhang admits he isn't clinging to power out of ambition; rather, he fears Liu Chu will become so lost in his feelings for Consort Ling that he will neglect the empire. Understanding Zhang's concern, Liu Chu vows to be a wise ruler but intentionally tries to outdrink the old man so he can finally return to his bride.

Meanwhile, General Xiao Chi and Fei Zheng receive a report on the plague in Huangpi Village. Their investigation reveals that the disease is remarkably similar to an outbreak from eight years ago but contains an unknown toxin. This confirms that the outbreak is not a natural disaster but a man-made act of sabotage. Later, when Liu Chu complains about his inability to spend a night with his wife, Xiao Chi and Fei Zheng promise to create an opportunity for him.

The Grand Princess, Liu Xie, remains vigilant regarding the palace's security. While pleased with the state of the treasury, she identifies Jin Xi as a potential threat. She visits Jiang Wanyu and, under the guise of concern for Jin Xi’s future, suggests it is time for the maid to have her own residence and life outside the palace. She offers a courtyard in the city and a monthly allowance.

Recognizing that there is no room for negotiation without exposing her true identity, Jin Xi is forced to accept the arrangement and prepare to leave the palace. The following night, Lord Zhang attempts to seek out Liu Chu with more business, but Xiao Chi and Fei Zheng arrive as reinforcements. They enthusiastically drag the meddling minister away to Tianxiang Restaurant to discuss old stories from Tianlang Pass.

Finally free of interruptions and with the help of nuptial wine sent by Liu Xie, Liu Chu and Jiang Wanyu are able to consummate their marriage. The next morning, Liu Chu takes Wanyu to the city gate. Looking out over the vast landscape, he swears that Jinglan and Changmo will remain at peace, vowing that future generations will never know the horrors of war. In the palace of Changmo, the atmosphere is far more hostile.

The King and his advisors are already plotting an assault on the nearly impenetrable Tianlang Pass. While General Gan Yi prepares the troops, Advisor Modu suggests a high-efficiency, low-cost strategy. The King decides to send Modu along with the tribute envoy to the capital to officially activate their long-term spy, Fei Zheng. Looking toward the future with cold resolve, the King vows to conquer Jinglan and send Liu Chu to the grave to join his father, Liu Zheng.

Jiang Wanyu and Liu Chu finally consummate their marriage, bringing the Princess a sense of long-awaited happiness and security. This joy coincides with the day Jin Xi is scheduled to leave the palace. Relieved to see Wanyu truly loved and cared for, Jin Xi prepares for her departure. To honor her service to the new Consort Ling, the Eldest Princess, Liu Xie, arranges for Jin Xi to be seen off through the main palace gates with grand ceremony.

As the gates close, Jiang Wanyu watches her friend leave, hoping for a reunion while Jin Xi moves into a residence arranged by the court. Meanwhile, Xiao Chi leads Han Yunling to a weathered warehouse, claiming he needs her help to inventory goods. To her surprise, the building is actually a fully stocked pharmacy. Xiao Chi has gathered precious medicines, including reishi mushrooms, ginseng, and the rare "Jewel Orchid" (Jin-xian-lian), gifting the entire shop to her.

Moved by his gesture, Yunling accepts the pharmacy, vowing to use her skills to save lives and bless the people, just as Xiao Chi inscribed on her shop's plaque. On their way back, the two discuss the massacre of the Han family, noting that the recent village plague shares disturbing similarities with an epidemic from years ago. They realize the truth likely lies with high-ranking officials who survived that era, specifically Zhang Ruizhong and Wang Ruhai.

At the same time, Wang Ruhai grows increasingly resentful. Already bitter about being forced into retirement, he becomes enraged when a grieving father demands the return of a daughter kidnapped by Wang’s son, Wang Kun. Believing Xiao Chi is behind these legal troubles, Wang Ruhai swears to retaliate. Han Yunling's peace is soon shattered by a terrifying nightmare of Huangpi Village engulfed in flames.

Fearing it is a premonition, she and Xiao Chi rush to the village, only to find the nightmare has become a reality. The villagers have been slaughtered, and the perpetrators—a group of masked men in black—remain on the scene. During the ensuing skirmish, Xiao Chi is struck by a poisoned dart while protecting Han Yunling. Though they manage to escape, Xiao Chi’s condition rapidly deteriorates as the venom takes hold.

Desperate to save him, Han Yunling searches the capital for medicine, but every pharmacy has been emptied of the specific herbs she needs. Fei Zheng consults an Imperial Physician and discovers that the weapon was coated in krait venom. The physician suggests that the only hope lies in using "poison against poison" with legendary ingredients like Blue Snake Tail or Snake Herb.

While Han Yunling works to stabilize Xiao Chi’s heart meridian, Fei Zheng’s investigation confirms that Wang Ruhai ordered the assassination. He presents evidence of the Wang family's numerous crimes to Liu Chu, urging the Emperor to act. Driven by a need for answers, Han Yunling confronts Wang Ruhai at his manor, demanding the truth about the Han family's death.

The arrogant official initially refuses to speak, but his resolve breaks when the Imperial Guard arrives with a decree to arrest his son for kidnapping and other crimes. In a desperate bid to save Wang Kun, the official offers to trade the truth for the boy's freedom. However, the shock and rage prove too much for Wang Ruhai; he collapses and dies on the spot, taking the secrets of the past to the grave.

Amidst the chaos, the Eldest Princess, Liu Xie, focuses on her own shadow play for power. Seeing the old guard like Wang Ruhai falling away and Zhang Ruizhong aging, she begins consolidating her influence, using the "Xie Shadow Guard" to monitor those around the Emperor and keep watch over Jin Xi at her new residence. She feels confident that as long as Liu Chu remains obedient, the entirety of Jinglan will remain under her control.

With Xiao Chi still unconscious and his life hanging by a thread, Han Yunling refuses to give up. She decides to personally track down the legendary herbs in the treacherous terrain of North Mountain. Risking her life on the steep cliffs, she eventually finds the medicine growing in a narrow crevice.

Despite nearly falling to her death during the harvest, she manages to secure the herb and returns to Xiao Chi's side, determined to be the one to protect him this time.

After enduring the treacherous cliffs to retrieve rare herbs, Han Yunling returned to the capital and collapsed from exhaustion. Xu Chengfeng, knowing she would want to be near the General, placed her by Xiao Chi’s side. When she awoke, her hands were still tightly gripping the medicine. She immediately began brewing the herbs, but to her distress, Xiao Chi showed no improvement after a full day of treatment.

Meanwhile, Emperor Liu Chu took a blindfolded Jiang Wanyu out into the city. To give her a taste of commoners' lives, he had bought out an entire street so they could stroll through the night market undisturbed. Moved by his gesture, Jiang Wanyu picked out various trinkets to send back to her people in Changmo as return gifts for an upcoming delegation. During their time together, they shared "Zhu Yao," a fruit symbolizing eternal love and many children.

The arrival of Uncle Lie in the capital brought a surge of hope. Han Yunling was overjoyed to inform him that her brother, Han Mo, was alive, though still unconscious in a quiet cottage. Uncle Lie, who had traveled with a merchant caravan following the new alliance, suggested moving Han Mo to Jie'an Ward for better care. Witnessing her uncle's medical expertise, Han Yunling felt certain that Xiao Chi could finally be saved.

In the shadows, the Hall Master (Meng Ling) confronted Fei Zheng, reminding him of his identity as a Changmo spy. She threatened to expose his secret to his "brother," the Emperor, and used the life of Jin Xi to force his cooperation. During a banquet for the envoy Li Shichang, Fei Zheng recognized Jin Xi among the Changmo dancers.

When the Hall Master attempted to humiliate Jin Xi, Fei Zheng intervened, but the Hall Master used a bell to trigger a painful Gu poison in both of them. She offered Fei Zheng a single antidote; to protect Jin Xi and maintain his cover, he claimed she was merely a tool and took the pill himself. The Changmo delegation soon arrived with tributes of pomegranates, figs, and yellow peaches.

Seeing the fruits of her homeland made Jiang Wanyu nostalgic, and Liu Chu promised to one day accompany her back to visit her father. During their conversation, Jiang Wanyu admitted she had been unusually sleepy and hungry, leading her to suspect she was pregnant. Liu Chu was ecstatic, dreaming of a future filled with children and teaching them how to govern.

Danger found Han Yunling when the Hall Master, disguised as a vendor, tried to lure her with a poisoned pomegranate. Uncle Lie intercepted them just in time. It was revealed that Uncle Lie was actually the renowned Strategist Mo Du, and he had once taught the Hall Master the very Gu techniques she now used. That night, she broke into his residence to question why he helped Xiao Chi.

Unfazed, Uncle Lie stated they had a division of labor and revealed he knew of her secret affair with the King of Changmo, leaving her with no leverage over him. With a potent antidote provided by Uncle Lie, Han Yunling hurried to Xiao Chi’s side. After taking the pill, the General finally regained consciousness. He thanked her for her tireless care, feeling a debt to her that he could never fully repay.

As he recovered, news of Jiang Wanyu’s pregnancy reached Princess Liu Xie. The Princess visited the expectant mother, bringing a set of Liu Chu’s childhood clothes in a rare moment of familial warmth. The peace was shattered when Emperor Liu Chu suddenly collapsed. As Zhang Ruizhong and Li Shichang were discussing the patience required for tea and life, news of the Emperor’s illness arrived. The Imperial Physicians were in a panic, unable to determine the cause.

Liu Xie, furious at their incompetence, ordered those who couldn't help to be punished. Suspicion fell on the Changmo tributes, prompting Xiao Chi and Fei Zheng to recommend Han Yunling. Citing her success in Huangpi Village and her knowledge of Changmo toxins, the Princess ordered Xiao Chi to fetch her immediately.

To stabilize the court during the Emperor's crisis, Chief Grand Secretary Zhang Ruizhong hid the full extent of Liu Chu's condition, maintaining a composed demeanor during morning sessions. When other ministers expressed fear of chaos following rumors of the Emperor’s grave illness, Zhang Ruizhong asserted his authority as the late Emperor's appointed official. He threatened to punish any Imperial Physician spreading "nonsense," successfully silencing the court for the moment.

Meanwhile, Jiang Wanyu was consumed by grief, weeping over the unconscious Liu Chu and refusing to believe he might not recover. Her vigil was interrupted by Princess Liu Xie, who reprimanded the attendants for allowing anyone near the Emperor without her orders. Concerned for the imperial heir, Liu Xie ordered Jiang Wanyu back to her palace, reminding her that her primary duty was to protect the child she was carrying.

Outside the hall, the Imperial Physicians were locked in a futile debate over treatments like Scutellaria and Forsythia. Han Yunling stepped forward, bluntly criticizing their unsuitable prescriptions. While the veteran physicians were dismissive of her, she was recognized by Uncle Song, who had served as an assistant to her father, the late Physician Han. Uncle Song promised to keep her identity a secret and provided the medical records detailing Liu Chu’s persistent fever and bruising.

After reviewing the symptoms, Han Yunling concluded that Liu Chu was not suffering from a natural illness, but from a rare poison. She asked Xiao Chi to fetch the list of tribute gifts and the Emperor's daily records to investigate further. Her goal was to find the source of the poison and clear Fei Zheng of any potential suspicion before his enemies could frame him for negligence. The investigation into the poison revealed a darker plot.

Jin Xi questioned Fei Zheng about the Hall Master’s involvement, suspecting a new spy had been sent to target the Emperor. While Fei Zheng offered Jin Xi an antidote and urged her to return to Changmo, she was reluctant to remain indebted to him. It was eventually revealed that the Hall Master was using poison to control the official Li Shichang, who was the one responsible for poisoning the Emperor.

As Han Yunling worked tirelessly through the night to find a cure, Xiao Chi stayed by her side to care for her, eventually falling asleep from exhaustion. The next day, the atmosphere in court grew volatile. Ministers began voicing suspicions that the empire’s recent misfortunes were linked to Xiao Chi and Fei Zheng’s return. Though Zhang Ruizhong and Li Shichang appeared to defend the two men, their words subtly stoked the court’s doubts.

Wary of treason, Liu Xie ordered her Xieying Guard to be ready for action. When Han Yunling officially presented her findings that Liu Chu had been poisoned, Liu Xie responded by confining Jiang Wanyu to her palace as a suspect. That night, Xiao Chi and Fei Zheng kept a somber watch over the Emperor, pouring a cup of wine for their unconscious brother and reminiscing about their carefree childhood.

During the watch, Xiao Chi suddenly coughed up blood—a lingering effect of his own previous poisoning. He begged Fei Zheng not to tell Han Yunling, as he did not want to distract her from saving Liu Chu. Meanwhile, Li Shichang visited Zhang Ruizhong with a collection of rare ancient books. He steered the conversation toward the future of the throne, questioning what would happen if the Emperor never woke.

Li Shichang pointed out the uncertainty surrounding the unborn heir and suggested that Zhang Ruizhong, as the head of the ministers, should seize the opportunity to take control of the empire himself. Appalled by this treasonous suggestion, Zhang Ruizhong reaffirmed his absolute loyalty to the Liu bloodline. Realizing he could not persuade the Secretary, Li Shichang feigned a sudden flare-up of chest pain and hurried away, pointedly leaving the books behind.

Xiao Chi visited the medical chambers with snacks for Han Yunling, concerned that her tireless research for an antidote was ruining her health. Han Yunling insisted she was fine and showed him a small bed where she could rest, though it was far less comfortable than her home. Xiao Chi decided to stay and keep her company, masking the fact that he had been secretly coughing up blood for several days.

The next day, Liu Chu’s condition took a turn for the worse. Han Yunling and Xiao Chi rushed to the Emperor’s side, where the Imperial Physicians were in a panic as the ruler had been unable to eat or drink for days. Upon examination, Han Yunling discovered a Gu worm moving beneath the Emperor’s skin. Despite the physicians' horrified protests against using a blade on the Emperor, Han Yunling performed an emergency procedure to cut the parasite out.

Xiao Chi stood by her, declaring he would take full responsibility for the consequences. Princess Liu Xie arrived at the palace shortly after the procedure. Although the physicians accused Han Yunling and Xiao Chi of harming the Emperor, Liu Xie granted them her forgiveness after learning they had removed a poison that had previously gone undetected. Meanwhile, in the Noble Consort Pavilion, a pregnant Jiang Wanyu was consumed by worry.

She summoned Fei Zheng, who informed her that while the worm was gone, Liu Chu had not yet regained consciousness. He urged her to focus on her health and the safety of the imperial child. Han Yunling soon brought a newly developed antidote to Liu Chu. However, after consuming the medicine, Liu Chu’s body began to convulse violently. He cried out for his elder sister in his sleep before suddenly losing his breath.

The Emperor was pronounced dead, sending the room into chaos. Enraged and grieving, Liu Xie ordered Xiao Chi and Han Yunling to be thrown into the imperial prison and sealed the palace gates, threatening to execute the families of anyone who leaked news of the Emperor’s passing. As Liu Xie mourned, she recalled her father’s final instructions to assist her brother, despite her own superior intellect. However, the state required a leader.

In the imperial court, ministers were already debating the succession. Li Shichang and others began pushing Zhang Ruizhong toward the throne, claiming it was the will of the people. Although Zhang Ruizhong protested that it was an act of treason, the ministers continued to urge him to take the seat. The proceedings were interrupted when Liu Xie marched into the hall. She challenged the ministers, reminding them that the Liu family was still in power.

When some questioned the precedent of a female ruler, she had the dissenters executed on the spot. Asserting her bloodline and her years of managing the treasury, she prepared to take the throne. Just as she was about to sit on the dragon chair, Liu Chu appeared at the entrance of the morning court, alive and well.

It was revealed that the "death" was a calculated plan between Liu Chu and Han Yunling to draw out those harboring ambitions for the throne. Now back in power, Liu Chu resumed his seat and offered Liu Xie a chair, though his demeanor toward her was notably cold. This reminded Liu Xie of her childhood, when her father bypassed her for the succession simply because of her gender.

To ensure stability, Liu Chu opened the national treasury and granted all ministers three years' worth of salary as a reward for their service during his illness. The peace was short-lived when Li Shichang stepped forward to accuse Zhang Ruizhong of harboring a dragon robe in his home, a clear sign of intent to usurp the throne. Xiao Chi was ordered to investigate and produced the hidden robe from Zhang’s residence.

Despite Zhang Ruizhong’s desperate claims that he had been framed, Li Shichang testified that Zhang had once boasted while drunk about his plan to rule. Consequently, Liu Chu sentenced Zhang Ruizhong’s family to execution and placed the old minister under permanent house arrest. Later, Liu Chu met with Jiang Wanyu. She expressed her immense relief, telling him she had prayed to exchange her life for his while he was unconscious.

Liu Chu reacted with a joke, asking if she intended to follow through on that promise now. His tone then turned serious as he questioned her about how he had been poisoned, specifically asking if the tribute food from Changmo was the source. Jiang Wanyu pointed out that since she had eaten the food and remained healthy, the poison must have come from elsewhere. She then recalled that the only item given exclusively to Liu Chu was the string of Zhuyao beads.

That night, Liu Chu visited Jiang Wanyu, his suspicion lingering over the string of Zhuyao beads she had given him. Jiang Wanyu defended herself, arguing that if the fruit had been poisoned, she would have fallen ill first. She insisted that she had washed them thoroughly and followed the customs of Changmo with no ill intent. Liu Chu feigned affection, telling her he could never truly suspect his own consort and urging her to rest.

However, when an attendant arrived with a secret report, Liu Chu immediately withdrew. The investigation confirmed that Huo Ran was indeed a spy planted by the late Emperor to monitor Fei Zheng. Huo Ran reported that while Fei Zheng had been reliable in the past, his behavior had become increasingly suspicious since his return from Tianlang Pass.

Troubled by the growing web of deceit, Liu Chu decided to sleep alone, admitting he could no longer trust anyone enough to sleep by their side. Meanwhile, Jin Xi was in the throes of agony, her body wracked with pain as the poison within her went untreated. Fei Zheng confronted the Hall Master of the Changmo organization, demanding the antidote before Jin Xi succumbed.

The Hall Master remained cold, mocking Fei Zheng’s attachment and reminding him that he was merely a pawn of Changmo. Fei Zheng pointed out that he had suffered for years undercover and had risen to a high ministerial rank for their cause, yet the organization had never truly supported him. He bargained with the Hall Master, stating that if he was to complete his mission, he needed Jin Xi’s assistance.

Relenting slightly, the Hall Master granted a single antidote but warned Fei Zheng that his own fate would be just as agonizing when his poison eventually took hold. At the same time, Zhang Ruizhong sat under house arrest, waiting for the inevitable. Xiao Chi arrived to find the old official prepared to drink a final pot of wine.

Zhang Ruizhong lamented that while he was accused of treason, the Emperor already knew that the dragon robe found in his home was a plant by Li Shichang. He realized that Liu Chu had grown up and no longer needed his guidance, making these false charges a convenient excuse to discard an old servant. When Xiao Chi questioned him about the massacre in Huangpi Village, Zhang Ruizhong admitted his guilt.

He confessed that eight years ago, a strange plague had turned the capital into a living hell. His only son had died after taking a prescription from the Han family, and in his grief-driven hatred, he had used his power to annihilate them. He also revealed that he was the one who recommended Xiao Chi to Tianlang Pass, fearing that Fei Zheng harbored dangerous secrets.

After warning Xiao Chi that an emperor is a man one can share hardship with but never prosperity, Zhang Ruizhong drank the poison and died. Following the turmoil, Liu Chu held court to distribute rewards and reassign his officials. He honored Han Yunling with gold and brocade for her medical service but moved Fei Zheng from the Ministry of Revenue to the Ministry of Rites.

Though presented as an honor to uphold the dignity of the state, the move effectively stripped Fei Zheng of his practical power by placing him in a sinecure. Later, Liu Chu met with the Eldest Princess, Liu Xie, to discuss new policies regarding the taxes from border fiefs. His sudden interest in the treasury ledgers alarmed her, as he had never cared for such administrative details before.

Liu Chu reminded her that their father, the late Emperor, had never allowed others to control the accounts and had even executed his own brothers to secure his throne. Liu Xie realized that Liu Chu was no longer the controllable brother she once knew. Seeing the same ruthlessness in his eyes that their father once possessed, she feared he would soon demand the keys to the treasury.

Deciding that she could not afford to wait for him to move against her, she instructed her guards to prepare for a banquet at the Princess's Mansion the following night. She intended to strike first before Liu Chu could fully consolidate his power. Xiao Chi, meanwhile, was desperate to help Han Yunling recover her lost memories. He brought in physicians and even resorted to spiritual rituals, chanting for the spirits to manifest, but his efforts yielded no results.

Han Yunling eventually told him to stop, suggesting that perhaps things were fine the way they were and that she didn't need to look back at the past. Fei Zheng later met with the Emperor, accidentally addressing him as "Big Brother" before quickly correcting himself to a formal greeting. Liu Chu brought up Fei Zheng’s past as a mountain hunter, suggesting a future hunting trip with Xiao Chi.

Fei Zheng claimed his father had died too early for him to learn the trade, and that he had been sold into the manor after being abducted by traffickers. Liu Chu spoke of how their shared history as commoners who rose to high ranks would be celebrated in the chronicles of the realm.

He invited Fei Zheng to the upcoming banquet at the Princess's Mansion, but Fei Zheng declined, citing the heavy workload of his new position at the Ministry of Rites. As Fei Zheng left the palace, he spotted the Eldest Princess’s personal attendants leaving secretly. He followed them to a remote courtyard where he witnessed Liu Xie giving serious instructions to a group of masked men, filling him with a sense of dread.

Following the suspicious meeting witnessed by Fei Zheng, the Eldest Princess, Liu Xie, took the initiative by hosting a banquet for Emperor Liu Chu. Liu Chu arrived late, accompanied by Xiao Chi, explaining that he had been occupied with the extensive treasury ledgers provided by his sister. During the meal, Liu Chu offered a solemn toast to their late father. Sensing the underlying tension, Liu Xie mockingly asked if he feared the wine was poisoned.

To maintain a facade of sibling unity, they shared from the same bottle, though the atmosphere remained heavy with hostility. Away from the banquet, Jiang Wanyu was plagued by an ominous premonition. Back at the table, the pretense finally shattered. Liu Xie lashed out, accusing Liu Chu of incompetence, murdering ministers, and allowing a toxic plague to ravage the people while he emptied the treasury for his marriage ceremony.

She demanded his abdication, proposing that she would rule and raise Jiang Wanyu’s unborn child to take the throne. When Liu Chu refused, Liu Xie signaled her hidden assassins. Black-clad guards swarmed the room, and Xiao Chi stepped forward to protect the Emperor. The situation was dire until Fei Zheng arrived, demonstrating lethal swordsmanship. Together, the three brothers suppressed the rebellion and took Liu Xie into custody.

Following the failed coup, Liu Chu stripped his sister of her titles and confined her to the Princess’s Mansion, decreeing that she was never to leave until her death. Meanwhile, Xiao Chi was deeply troubled by the battle. He realized that Fei Zheng had been hiding his true strength and that his swordplay was a distinct style from Changmo. Seeking solace, Xiao Chi drank with Han Yunling and reminisced about the days when the three brothers had no secrets.

Disturbed by the complexity of palace politics, he decided to return to Tianlang Pass to guard the border and asked Han Yunling to accompany him, gifting her a pouch as a symbol of his promise. In the shadows, the Hall Master of Caidie Hall prepared to return to Changmo, her current mission complete. Before leaving, she provided Jin Xi with a temporary supply of antidote for her poison but reminded her that she remained a mere tool for their cause.

The next morning, Jiang Wanyu woke from a nightmare to find that Jin Xi had successfully returned to the palace. While Jiang Wanyu felt a sense of gratitude toward Liu Xie for her past kindness, Jin Xi warned her to stay away. She pointed out that a woman willing to murder her own brother would never be sincere toward a sister-in-law, and that the internal strife of the Liu family was not something the Princess of Changmo should interfere with.

In Changmo, the Hall Master reported her progress to the King. She confirmed that two of the three chief ministers were dead, the third was poisoned, and Liu Xie had been neutralized. With Fei Zheng still undercover and controlled by poison, the plan to dismantle Jinglan moved forward. The King, despite his own weakening health, remained focused on his goal of capturing Liu Chu and spreading a new, more potent poison throughout the empire.

Liu Chu eventually paid a final visit to his sister. He admitted he had always been jealous of her, as their father had raised her with the arts of a ruler, mastering everything from strategy to the manipulation of men. He confessed that if she had been born a man, he would have had no chance at the throne.

However, he could not allow her to live with such ambition and presented her with a cup of poisoned wine, promising to bury her with imperial honors as if she had died of a sudden illness. Liu Xie accepted her fate, drinking the wine and expressing hope that he would prove himself a capable ruler. The palace soon announced that the Eldest Princess had passed away due to a severe illness.

Following her grand burial, Fei Zheng met Jin Xi in a quiet bamboo forest. He spoke of his childhood and how the three brothers used to cause trouble and fight for justice on the streets, remembering the rare warmth he felt when Liu Chu and Xiao Chi cried for him after he took a beating on their behalf. Unbeknownst to them, Huo Ran was watching from the shadows.

Later, Liu Chu visited Jiang Wanyu at the Ling Pavilion, strictly ordering her to stay inside for her safety while he prepared a secret plan. That night, he summoned Xiao Chi and Fei Zheng for a drinking session. When a late-arriving Fei Zheng offered to drink three pots of wine as a penalty, the three brothers toasted to each other, though the weight of their secrets hung heavy over the table.

Liu Chu hosted a banquet for Xiao Chi and Fei Zheng to bid farewell to Xiao Chi before his departure for Tianlang Pass. During the meal, Liu Chu expressed his wish for the wars to end so that the three of them could remain together in the capital. Xiao Chi remained resolute, vowing to protect the pass for the sake of the nation and its people.

However, Liu Chu questioned if Xiao Chi's loyalty was truly for the people or for the Emperor himself. Sensing the tension, Fei Zheng intervened, explaining that Xiao Chi viewed the Emperor as the "heaven" of the people. Despite the camaraderie, Liu Chu secretly harbored suspicions about Xiao Chi’s true intentions. Meanwhile, Han Yunling discovered a way to treat memory loss in an ancient medical manual.

She studied the techniques for the Neiguan and Shenmen points to regulate her qi and calm her mind. Though she knew the Baihui acupoint was dangerous, she decided to take the risk to regain her past. As she performed the acupuncture on herself, flashes of her childhood surfaced. She remembered a young boy who had saved her from a deep river and promised to go to battle to protect her and the people of Jinglan.

She realized with certainty that the boy was Xiao Chi. Back at the banquet, the atmosphere shifted when Fei Zheng suddenly began coughing up blood. Although he claimed he had simply caught a cold due to the turning weather, Xiao Chi suspected the wine was poisoned. To test his suspicion, Xiao Chi offered to toast the Emperor using Fei Zheng’s wine. Sensing the distrust, Liu Chu took the pot and drank it himself to prove there was no foul play.

Xiao Chi immediately apologized for his impulsiveness and asked if Liu Chu would ever forgive him if he made a grave mistake. Liu Chu reminded them that the three of them grew up like brothers and promised that his word as Emperor was his bond; he would pardon them even for serious crimes, though he admitted that if his closest friends betrayed him, he would have no one left to trust.

The following morning, Han Yunling’s demeanor toward Xiao Chi changed completely. Filled with the warmth of her recovered memories, she visited him before he left for the palace and tenderly kissed him goodbye, leaving Xiao Chi stunned. Elsewhere in the palace, Jiang Wanyu felt increasingly isolated. Her maid, Jin Xi, brought her grapes sent by the King of Mo, but Jiang Wanyu lamented that they no longer tasted as they once did.

She felt that Liu Chu had become a stranger, yet she still hoped the child she carried might bring peace between Changmo and Jinglan. That night, Liu Chu ordered Xiao Chi to investigate reports of secret meetings, claiming Xiao Chi was the only person he could still trust. Xiao Chi followed the mysterious figure, who turned out to be Jin Xi. She headed toward the medical clinic to warn Han Yunling to return to Changmo quickly for her own safety.

Han Yunling was confused and followed Jin Xi as she hurried toward the outskirts of the city. In a secluded yard, Jin Xi met with Fei Zheng, who was suffering from the effects of Gu poison. It was revealed that Jin Xi had been saving an antidote for him, but Fei Zheng hoped they could both survive until Changmo invaded Jinglan to earn their true freedom. Their conversation confirmed they were both spies for Changmo.

Xiao Chi confronted them with his sword drawn, feeling deeply betrayed by Fei Zheng. A fight broke out, and the weakened Fei Zheng was eventually wounded. Just as Xiao Chi was about to let them flee, Liu Chu arrived with his guards. Xiao Chi pleaded for mercy, reminding Liu Chu of his earlier promise of a pardon. Liu Chu agreed to spare Fei Zheng if he confessed everything, but he made no such guarantees for Jin Xi.

Han Yunling rushed to the scene, tearfully begging the Emperor to spare Jin Xi’s life as a reward for her having saved the Emperor’s life previously. However, Jin Xi was ultimately killed. Before she died, she told Han Yunling how much she missed their days in Changmo and entrusted the care of Princess Jiang Wanyu to her. She looked at Fei Zheng one last time, wishing that in their next life, they could be free.

Following her death, a devastated Liu Chu ordered Fei Zheng to be taken to the Imperial Prison, strictly forbidding anyone from harming him because he still considered him a brother. The next day, Han Yunling brought the news of Jin Xi’s death to Jiang Wanyu. Heartbroken and feeling there was no love left for her in the palace, Jiang Wanyu expressed a desire to return to Changmo. She asked Han Yunling to find a beautiful place with trees and flowers to bury Jin Xi, and Han Yunling promised to see her friend off properly.

Han Yunling laid Jin Xi to rest in a peaceful spot surrounded by mountains and water. Reflecting on Jin Xi’s final warnings, Yunling finally understood the danger she had been cautioned about. Meanwhile, Xiao Chi struggled with his grief, drinking heavily as he lamented how his brotherhood with Liu Chu and Fei Zheng had fractured so tragically. Han Yunling cared for him as he slept, moved by the realization that he had never forgotten her during their years apart.

The peace was shattered when the King of Changmo ordered his master plan to commence. The strategist Meng Ling initiated the attack by releasing a deadly toxin into the wind, which swept through the capital. As high-ranking officials were systematically assassinated, a mysterious plague began to ravage the common people. Faced with the crisis, Emperor Liu Chu sought a solution.

While the minister Li Shichang ruthlessly proposed executing the infected, Han Yunling advocated for a strict quarantine and began searching for a cure within the Han family medical manuals. The situation worsened with news that Tianlang Pass had fallen to General Gan Yi’s massive army. Xiao Chi explained that the pass succumbed because half of its soldiers and citizens had already been incapacitated by the plague.

In an attempt to secure Xiao Chi's unwavering loyalty amidst the chaos, Liu Chu offered to decree a marriage between him and Han Yunling. However, Yunling deferred the matter, choosing to prioritize the development of an antidote. When Jiang Wanyu learned of her father’s advance on the capital, she offered to mediate a retreat.

Her gesture only fueled Liu Chu’s paranoia; he accused her of plotting to defect to Changmo and ordered her to be confined to her quarters to protect the royal heir she was carrying. As the military prepared for a final stand, Xu Chengfeng led his veterans to the front lines, though he was haunted by an uncharacteristic sense of dread. Back at the medical hall, Han Yunling worked feverishly, eventually discovering the cure by testing formulas on herself.

She found that reducing the dosage of red arsenic by half made the medicine safe and effective, and the antidote was immediately distributed throughout the city. Though the epidemic was brought under control, the capital remained under siege. While Han Yunling treated the remaining weak and elderly, Xiao Chi led the defense outside the city walls.

During a fierce engagement, Xu Chengfeng managed to overpower Gan Yi, only to be struck down and killed by a hidden arrow fired by Meng Ling. With the city's defenses crumbling, Li Shichang once again urged Liu Chu to surrender. Realizing the minister was a traitor controlled by Changmo's Gu poison, the Emperor executed him on the spot, vowing never to be a ruler who abandoned his kingdom.

In the midst of the crisis, Uncle Fan arrived at the medical hall to urge Han Yunling to flee to Changmo. During their confrontation, he confessed to a dark secret: years ago, he had secretly added potent, dangerous drugs to the family's prescriptions in a reckless bid for fame. His actions had caused the deaths that led to the Han family's ruin and massacre. Yunling was horrified to learn that her own uncle was responsible for their family's tragedy.

Uncle Fan further admitted to orchestrating the current plague as a means of revenge, claiming it would bring glory to the Han name. Revolted by his cruelty and his betrayal of their family's medical ethics, Han Yunling cut all ties with him, refusing to leave the city with a man she now considered a sinner against the world.

Liu Chu visited the prison with a jar of wine, the same vintage he, Xiao Chi, and Fei Zheng had brewed together years ago. He mocked Fei Zheng, revealing that Li Shichang had died from poison at court and the Changmo army was already at the gates of the capital.

Though Fei Zheng confessed to being a spy sold to the Changmo military as a child, he insisted that the warmth he felt from Liu Chu and Xiao Chi in Jinglan was the first time he truly felt human.

Liu Chu initially intended to keep him alive to witness the destruction of Changmo, but Fei Zheng, seeking a release from his guilt, deliberately provoked the Emperor by claiming it would soon be too late for Liu Chu to take his life. Enraged, Liu Chu stabbed his former brother. In his final moments, Fei Zheng begged to be buried in the bamboo forest where they once shared happy memories, praying for the Emperor’s health and the peace of Jinglan.

Covered in blood, Liu Chu went to see Jiang Wanyu. Heartbroken and horrified by the deaths of those close to the Emperor, she realized she might be the next to die. Liu Chu defended his coldness as the burden of a monarch who could no longer trust anyone. Jiang Wanyu lamented the irony of her title as Princess Heshan, as her husband and her father were now poised to kill each other.

When asked who she would choose, she declared she would not live if Liu Chu died, yet she mourned that the man she once loved had changed into someone who only loved himself and his power. To her, even the name of their unborn child seemed irrelevant now that their world had fallen apart. At dawn, Xiao Chi prepared to depart for the front lines.

His master, Liu Xiyang, presented him with an ancestral spear, urging him to use it well and return it personally after the victory. On the city walls, Liu Chu watched as Xiao Chi rallied the troops, declaring that with their families behind them, there was no room for retreat. Han Yunling, determined to help, followed the army to the battlefield to provide medical aid despite the danger.

As the battle commenced, Jiang Wanyu rushed to the front lines, pleading with her father, the King of Changmo, to withdraw. She begged him to remember his promise of peace and mentioned that her unborn child—the bond between their two nations—was proof that the fighting should end. However, the King remained unmoved and ordered a full-scale charge. Amidst the violent clashing of armies, Jiang Wanyu went into labor.

Han Yunling braved the chaos to reach her and assist with the delivery on the battlefield. Xiao Chi fought with ferocity and succeeded in killing the enemy general Gan Yi. While the war raged around her, Jiang Wanyu endured the pain of childbirth while drifting through memories of her past with Liu Chu. When a daughter was finally born, Jiang Wanyu begged Han Yunling to take the infant away and hide her so that Liu Chu would never find her.

The Hall Master tried to seize the baby to "protect the royal bloodline," but Xiao Chi intervened, allowing Han Yunling to escape with the child. Xiao Chi eventually killed both the Hall Master and the King of Changmo with his arrows. Though surrounded by the remaining Changmo forces, he fought to his last breath to secure the victory for Jinglan. Still believing Fei Zheng was alive, he called out to Liu Chu to honor his promise and release their friend.

As the battle ended, Liu Chu descended from the city walls to find Jiang Wanyu. Pale and weak, she told him he would never see his child before she died from a massive hemorrhage. Nearby, seeing the King dead and his cause lost, Fan Ershu committed suicide by taking poison. In the aftermath, a maddened Liu Chu searched everywhere for Han Yunling and the baby, but found nothing.

In a final, horrific act of vengeance, he ordered the massacre of hundreds of thousands of surrendered Changmo soldiers. Years later, Han Yunling and the young girl, Yue'er, lived in the vast desert. Yue'er questioned why they visited the border every year, and Han Yunling explained it was the only place where they could still see the shadow of Jinglan and those who loved them. Eventually, they traveled to the General's Mansion at Tianlang Pass. While Yue'er explored the house, Xiao Chi finally appeared before Han Yunling, marking a silent, long-awaited reunion between the two.
