Description

When a natural disaster strikes, everyone travels through the wasteland world and faces the challenge of death and survival!
Horrifying acid rain, monstrous floods, burning cities, global glaciers, super radiation....
No one is immune!
If humans want to survive, they can only build shelters and accept the baptism of natural disasters one after another.
Fortunately, Sumo awakened the doomsday survival system!
His shelter can be infinitely upgraded!
【Wooden Door】→【Iron Door】→【Alloy Door】→.....
【Wooden Spear】→【Cinnamon Spear】→【Electromagnetic Spear】→.....
【Diesel generator】→【Biogenerator】→【Thermoelectric generator】→.....
While everyone is rushing to prepare for the next disaster, Somo is already fully equipped and running rampant in the wasteland world.
"We are still lighting oil lamps, and other people's refrigerators are used!"
"I heard that the walls of his shelter are dozens of meters thick, making it the safest place in the world"
"In my lifetime, I want to live in Sushen Sanctuary for one day."
