All human beings travel to a strange ocean world and survive in the stomach of a giant fish named Leviathan. Humans need to help the transformed Leviathan remove harmful organisms from the stomach, and the transformed Leviathan can find supply boxes for humans and help humans develop. The creatures in this ocean world are all extremely large, and even parasites are far larger than humans. Humans need to constantly obtain supply boxes, upgrade their abilities and equipment, and fight against these creatures that invade the stomach of the transformed Leviathan. When everyone was struggling, Zhou Wen had the unique ability to listen to the voice of the giant fish. On the first day he traveled through time, he received three times the supply boxes of others, and he was far ahead in the early days.
