National Doomsday: Build a Protective Umbrella from Scratch!

All human beings travel to another world. At the beginning, a biochemical virus breaks out and zombies swarm! While others are still struggling to survive, Lin Bei, who is bound to the base development system, has already started various businesses. "I never thought that I could order takeout in the apocalypse... Even at this price, I can't even afford it if it's sold!" "I picked up a lot of garbage today, I'm happy... But why do people come to the wild for a picnic in an armored convoy, escorted by fighter planes?!" "Thank you Lin Bei, thank you to the umbrella for rescuing me from the zombies... Even though the cost was fifty years of working for the umbrella!" "Help!! There are still capitalists in the apocalypse!!" This novel and its characters are purely fictitious.
