Hu Bayi and Wang Pangzi have removed the touch gold symbols and originally planned to go abroad with Shirley Yang. However, they were entrusted by Professor Chen to join Uncle Ming, who had been an old sea wolf, and traveled to the South China Sea Coral Spiral to search for the long-lost national treasure - the Qin Emperor's Bone Mirror. They purchased a powerful yet unused "Ghost Ship" Trident on Coral Temple Island and befriended the itinerant people Ruan Hei, Gu Cai, and Duo Ling, embarking on a journey together.
After experiencing various maritime wonders and a great battle with ghost ships, the group finally entered the mysterious and dangerous Coral Spiral sea area. After several dives, Hu Bayi roughly determined the location of the sunken ship carrying the "Qin Emperor's Bone Mirror."
However, at this time, coinciding with the full moon, the underwater Yin fire rekindled, and the "door" of the Guixu Sea opened, sucking them into the strange Guixu sea cave. Guixu is like a magical "sea within the sea," isolating the upper layer of seawater like a giant transparent bubble. Although everyone survived, they didn't know how to return to the sea surface.
In despair, they discovered the giant Sun Shooting Lever left by the Hentian Kingdom clan. Hu Bayi and Shirley Yang decided to use the lever mechanism to make a desperate attempt to escape from Guixu and return to Coral Temple Island.
