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..."

The Origin Territory was on a massive scale when looked at from a high place.

There were plenty of buildings on the top of the mountains.

Even people accustomed to seeing modern cities would still be amazed that human beings could build such a miracle among such mountains.

Before the arrival of the heavy snowfall, it was the "popular" gathering place of the electromagnetic wave communication platform.

It had a strong consumption power, considerable resource reserves, and another attribute that was difficult for others to replace…

The people who made up the territory were complicated, and there were too many sub-territories.

No one cared about the source of the countless supplies they sold, and neither did they care about how much blood was stained to obtain them.

It only took two or three days to arrive in Origin Territory, and there was no danger to traveling from the other side of the mountain before the heavy snowfall.
