A sudden global biochemical disaster destroyed the prosperous human civilization in an instant. Cities have been reduced to concrete tombs, and former compatriots have turned into bloodthirsty monsters. In this dead wasteland, resources are more precious than gold, and humanity is more terrifying than monsters.
An ordinary college student, Nangong Ye Baiyu, managed to survive in the chaos of the doomsday. He is not a hero, but driven by his survival instinct, he gathered several surviving classmates and formed a team to survive in the cracks. They used the abandoned university town as their base and carefully wandered through the ruins of the city, which was full of dangers. Every time they go out, it's a life-and-death game. For a few cans and a bottle of clean water, they have to fight against the mutants wandering the streets, and they have to be wary of the same kind who do whatever it takes to survive.
When the resources of the stronghold they relied on for survival were depleted, they were forced to embark on a more dangerous journey. The legendary "Ark" safe base is their only hope. But before they can find hope, they must survive. On this road full of despair and betrayal, Nangong Ye Baiyu and his companions will use their blood and will to write their own rules of survival.
