[The end of the world + system + infrastructure + management] A sudden virus turned the world into a living hell, and the end came quietly. Lin Wei accidentally obtained the interstellar landlord system, and won an S-class tank in the opening lottery! Use the system to slowly build a hope base, which has inexhaustible food and water. It is the strongest and safest holy place in the doomsday world, and a place where survivors can find the sun. Here, as long as you have crystal nuclei and gold, you can enjoy everything.
