On the eve of the doomsday, Li Zhan, the underworld overlord who lends money to the underworld, unexpectedly accepts a special mortgage - Lin Chi, who is frail and sick but has a superior IQ. His father ran away in debt, and Lin Chi became a debt bargaining chip. Before he could deal with it, the zombie virus swept across the world and the city turned into a purgatory.
Li Zhan was hard-spoken but soft-hearted, struggling to survive with this "oil bottle" who needed medicine to stay alive. While cursing and looking for supplies and medicine, he built a safety barrier for Lin Chi. In Doomsday, there are not only evolved zombies, mutated animals and plants, but also randomly triggered unlimited dungeons. Survivors are forced to participate in tasks every week, and if they fail, they will be wiped out.
The scale of the dungeon has expanded from the community to the world, and awakened ones have emerged. The elements of the five elements are intertwined with special powers, and the level climbing and points mall have hidden vitality. Although Lin Chi is weak, he uses his "data vision" to see through the loopholes in the rules and becomes the core think tank of the team; Li Zhan uses his "S-level immortal rage" talent to sweep away powerful enemies. From verbal dislike to personal care, the two form a fatal symbiosis in blood and fire.
They not only have to fight against zombies, man-made disasters and dungeon traps, but also pursue the truth of the doomsday - this disaster is actually a screening game for high-dimensional existence. Lin Chi's sky-high price healing potion is hidden deep in the mall, and the road to killing gods by closing the "Source of Silence" and subverting the rules is destined to be broken by this pair of underworld overlords and sickly geniuses. When violence meets wisdom, and when protection becomes instinct, can they rebuild order in a disordered world and reverse their fate?
