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..."

My Post-Apocalyptic Shelter Levels Up Infinitely!

The very first upgrade unlocked the second function of creation at 1000 survival points.

Su Mo had thought that unlocking the third function would still take quite a bit of time. He had not thought that it would be opened so suddenly!

When he killed the pseudo god using the DF-17 that he drew using the prize draw function from unlocking the creation function, he received ten thousand survival points despite the reduction due to having relied on the system's assistance.

"The kobolds sure were a treasure trove—both the second and third functions were opened thanks to their bodies!"

The moment he thought of the kobolds who had been exterminated, Su Mo could not help rejoicing.

Having such a strong enemy around the shelter was both a danger and an opportunity.

Silently focusing, he laid in the bath barrel and the system panel once again appeared in front of him.

Great Determination! The Talent Of The Strong!
