Alone at the End of the World: My Dark Contract

Reborn before the apocalypse, Xiao Ran used his foresight to hoard a large amount of supplies. He accidentally awakened a darkening system, embarking on a different kind of apocalyptic experience. While others struggled to find food, Xiao Ran enjoyed hotpot and ice-cold cola; while others hid in fear, Xiao Ran relied on his secure fortress to hunt with ease; while others cursed their fate, Xiao Ran had already evolved and awakened his powers. Crushing his old enemies beneath his feet, he said, "I don't want to kill you; I just want to torture you. I advise you not to test my patience!" (Source: Tencent, translated)
