---------------------------------
When natural disasters come, all people travel through the wasteland world and face the challenge of death and survival!
Horrible acid rain, monstrous floods, burning cities, global glaciers, super radiation...
No one is immune!
If human beings want to survive, they can only build shelters and accept rounds of natural disasters.
Fortunately, Sumo has awakened the doomsday survival system!
His shelter can be upgraded infinitely!
【Wooden door】→【Iron door】→【Alloy door】→.....
【Wooden Spear】→【Arbor Spear】→【Electromagnetic Spear】→.....
【Diesel Generator】→【Biological Generator】→【Thermoelectric Generator】→.....
When everyone was rushing to prepare for the next disaster, Sumo was already fully equipped and was running rampant in the wasteland world.
"We're still lighting oil lamps, and people's refrigerators are all in use!"
"His shelter is said to have walls tens of meters thick, and it is the safest place in the world."
"In my lifetime, I want to live in Su Shen Sanctuary for a day"
