Mutated fish swept the world, bitten people turned into fish corpses, cities fell one after another, and the remaining humans huddled in bases to survive.
Gu Yan just wanted to set up a small stall in a small base to survive stably, but he was bullied by the gangsters and unjustly imprisoned. In the detention center, facing the death penalty of buying the murderer to silence him, he fought back in a bloody manner and desperately escaped from the prison in an ambulance. Passing through countless dangerous situations all the way north, we finally entered a small village in the Hucha Wasteland. Gu Yan, who has nothing, will build a high wall here and build up his own group of survivors.
