All of humanity traveled to a strange ocean world and lived in the stomach of a giant fish called Leviathan.

Humans need to help the Transformed Leviathan remove harmful organisms from its stomach, and the Transformed Leviathan finds supply boxes for humans to help humans develop.

The creatures in this ocean world are extremely huge, and even the parasites are much larger than humans.

Humans need to constantly obtain supply boxes, upgrade their abilities and equipment, and fight these creatures that invade the stomach of the phantom Leviathan.

While everyone was struggling, our protagonist Zhou Wen, because he could hear the voice of the transformed Leviathan from time to time, obtained three times as many supply boxes as others on the first day of his travel, and was far ahead in the early stage.

Highlights: hardcore survival, home building, farming and breeding, character evolution, equipment upgrade, dungeon exploration, giant fish training, October in the sky, and sea hegemony.
