I Came Back from 2058 and Started Building the Doomsday City

Yan Guanlan mistakenly entered the wasteland future of 2058, saw the city collapse, resources were cut off, and his mother died on the eve of the disaster due to drug withdrawal. When he opened his eyes again, he returned to 2028, seven years before the first disaster. Everyone thought he was crazy: he sold his wedding house, broke off the engagement, settled old debts, spent money to buy cold storage, robbed logistics parks, took abandoned mining areas, hoarded medicine and food, and poured all his wealth into a doomsday city that no one believed in. His ex-girlfriend's family called him ruthless, his relatives called him a prodigal, and capital targeted his warehouse and mining area. Until heavy rain, power outage, plague, war and gray snow came one after another, those who once laughed at him finally stood outside the gate of Doomsday City, begging for a bowl of water, a bed, and an admission list. Yan Guanlan stood behind the city gate and only said: "Arrange according to the rules."
