Survivors in Radiation Hell

After the Third World War, the victors transformed the earth into a hell, and then threw it to the defeated and left gracefully. In this hell, radiation is like the god of death, collecting lifespan anytime and anywhere. The radiation contained in the crystal core of the monster is also like the devil, trading power for lifespan. Those who are lucky will die when their lifespan is deducted, and those who are unlucky will gain mutations when they trade with the devil, and become new monsters after death. Not long after Chen Nian came of age, he only had more than 20 years to live. When he made a deal with the devil, he unfortunately acquired a mutation. After being rescued by a group of people in a predicament, he followed this group of people. This group was as unfortunate as Chen Nian.
