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..."

Before the territory upgrade function was unlocked, Su Mo had once thought that the billion-level civilization upgrade function was the killer ace that he would have up his sleeve and that, as long as he could continuously upgrade his territory's civilization level, and improve the skill and knowledge levels of its residents, he could rapidly develop his territory and technology tree and overpower the other inhabitants of the New World.

However, after seeing the system panel on the territory upgrade function, Su Mo realized that he had it all wrong!

Instead of the slow and daunting road of civilization upgrade, this territory upgrade function had come at the perfect time, and it would be the most important aspect in his conquest of the New World in the future!
