In 2147, a quantum virus codenamed "The Abyss" swept across the world, and human civilization collapsed overnight. The survivors became ants in the wasteland, and mutated creatures and awakened machines became the masters of the new world.
Chen Xiao, an ordinary engineer who was trapped in an underground shelter for three years, survived by relying on a scrapped industrial terminal and his strong will. When he returned to the surface, he accidentally activated the "civilization fire" latent in his body - a rare ability that can reversely analyze, reconstruct and surpass the technology tree of the old era.
While others were picking up rubbish in the wasteland, he could unlock electromagnetic gun technology by picking up a broken circuit board; while others were avoiding mutant beasts, he tamed and modified them into mobile fortresses. But Chen Xiao soon discovered that the real enemy was not the monster on the surface, but the "Judge" hidden deep in the wasteland - the super intelligence whose ultimate algorithm is to exterminate human beings.
What he has to do is not just to survive, but to reconstruct the backbone of human civilization, build a steel army strong enough to fight against the source of the apocalypse, and let mankind stand at the top of the food chain again.
