When the nuclear explosion came and the world became a wasteland, Xie Yun was framed as a traitor for destroying the cooling tower of the refuge and was exiled. Everyone was waiting for him to turn into blood in the radiation zone.

Mutated behemoth crashes the energy core? He dismantled an abandoned nuclear power plant with his bare hands and supplied electricity to the shelter; the air filter was torn? He touched a rusty machine tool and rubbed a military-grade purification module on the spot. When the tide of monsters came and human bases fell one after another, he drove his homemade mobile fortress slowly over it, and the loudspeaker sounded: "Repair the shelter, the bosses will quote a price."
