While others scramble for canned goods in the apocalypse, Ling Yu directly reincarnates into a nuclear power plant! Armed with the Civilization Transition System starting from scratch, he employs robots as security guards, drones as the air force, builds bullets himself, and grows his own food. Skateboard warrior Shen Yan, veteran Zhang Wu, and virus expert Su Wan join forces one after another. With a hope elementary school opening, a cafeteria starting fires, and ID cards going live, they live out a vibrant, homely atmosphere even with mutants laying siege. Centipede monsters, archangels, and ancient nobles take turns attacking in waves. In front of absolute technology, they are all physically dispatched by him! Even better, in the apocalypse, he builds his refuge into humanity's final beacon!
