Jiang Chen was reborn three days before the outbreak of the apocalypse and bound the system. He decisively sold his house, took out a loan, used the system to hoard hundreds of thousands of tons of supplies, and bought unfinished buildings in the suburbs, upgrading them into "fortresses" with nuclear bomb-level defense. The apocalypse is coming, extreme cold and a wave of corpses are coming together. His ex-girlfriend and the rich second generation are shivering in the cold wind, but Jiang Chen is eating hot pot and singing in the safe house. The enemy tried to seize the safe house, but was ruthlessly controlled by Jiang Chen's drones and high-tech defense systems. Jiang Chen started on the road to hegemony in the apocalypse.
