南海归墟

Hu Bayi and Fatty Wang had planned to go abroad with Shirley Yang. However, they were entrusted by Professor Chen to travel to the Coral Spiral with Mr. Ming to search for the Qin Emperor's Bone Mirror. They befriended Ruan Hei, Gucai, and Duoling on Coral Temple Island. Together, they set sail. One night, they were sucked into the underwater cave of Guixu. In despair, Hu Bayi and Shirley Yang decided to risk their lives using the Sun-shooting wooden mechanism to lead everyone out of Guixu.

After washing his hands, Hu Bayi helped his friend Uncle Ming go to the South China Sea to salvage the pearls. Unexpectedly, he encountered a shipwreck and fell to the bottom of the sea, but accidentally found a thousand-year-old ruins of an ancient country that sank at the bottom of the sea. They went through many hardships and dangers at the bottom of the sea, and finally united to defeat the deep-sea beasts, and cleverly used the equipment in the ruins to escape.
