As disaster was about to strike, a group of survivors transmigrated into a desolated world and were challenged to a game of survival. From terrifying acid rains, to endless natural disasters, the heavens burn while the earth scorches, radiation is rampant, and nobody is spared from the dangers of this hellscape. The only way one survives is by building a shelter and slowly upgrading it in hopes of surviving another day. 
Luckily, Su Mo awoke a Doomsday Survival System that allowed him to infinitely level up and upgrade his shelter! The main shelter wooden door can be upgraded into a metal door, which in turn upgrades into a composite gate; the wooden spears can be upgraded into bronze spears, which eventually upgrade all the way into electromagnetic spears... While everyone struggled to survive, Su Mo was fully loaded, and well equipped to dominate the post-apocalyptic world. 
"While some of us are lighting oil lamps, he's been using refrigerators!" 
"The walls in his shelter alone are tens of meters thick, it's the safest place on this planet."
"Before I die, I wish to spend one day in his shelter..."

"Compared to Ma Fei and Magoo's generation, an increasing number of people from Earth have survived because of me.

"But at the same time, the butterfly effect brought about by so many people is also frightening enough.

"Because of how the rules of killing work, every time mankind falls, a foreign race will arise. If we don't resolve this, I'm afraid I'll become a "man without followers" in the new world!"

Driven into the wasteland to commit crimes, Zeus Shelter lived only to survive and journey to the new world.

An insignificant "little thing" such as this was like a microcosm of all mankind in the grand scheme of things.

The ocean disaster this time required not only the building of ships and stocking up of supplies, but they also had to guard against any possible covert attacks by foreign races at any time.

For the weaker people in the wasteland, this was absolutely beyond their capabilities.

Conquest! Link the Foreign Race Cores!
