On the eve of the doomsday, programmer Lu Chen accidentally activated the "infinite redemption system" and used the monster killing points and mission rewards to redeem materials/skills through a draw in the system mall. He pretends to be an ordinary survivor, but in reality he is hoarding nuclear bombs, building fortresses, and taming mutant beasts. Along the way, he recruits the silly and sweet healer Su Tang, the arrogant and cool Gu Qinghuan, and the twin sisters Hua Ye Chuqing (a time-travelling girl) and Ye Chuxue (a reborn girl). In the battle for base supremacy, he crushes the blackened city lord, outsmarts the apocalyptic natural disaster, and finally reveals the source of the virus and leads mankind to rebuild civilization.
