The story is about Song Tianyin, who unexpectedly becomes pregnant and gives birth to a cute monster named Huba.
He joins forces with Taoist Huo Xiaolan to protect her "son" against the demon realm.
A long time ago, humans and all creatures coexisted, including demons. However, humans wanted to dominate the world, so they declared war on demons and banished them deep into the mountains and forests, establishing a boundary between humans and demons.
One day, a pair of demon lovers named Zhu Gao and Pang Ying disguised themselves as humans to protect the demon queen, who was carrying the young demon king, from the pursuit of blood demons.
They arrived in Yongning Village and met the kind-hearted Tianyin, the demon-hunter girl Huo Xiaolan, and the Taoist Luo Gang who opposed Xiaolan.
Tianyin witnessed the war between humans and demons and was surprised to discover the existence of demons. To protect the young demon king, the demon queen entrusted him to Tianyin, who swallowed the egg without hesitation and became a "pregnant man".
Ge Qianhu offered a hefty reward for the demon king. In order to obtain the reward, Xiaolan dragged Tianyin, who had never left Yongning Village, to evade Luo Gang's pursuit and embarked on a magical journey, encountering various characters such as the owner of the gambling house, the chef Taoist, and a pair of cute demons.
The birth of the adorable young demon king Huba brought about a strange change in the relationship between Tianyin and Xiaolan and also revealed a major secret.
