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..."

Imagine boldly, but verify carefully.

As a stalwart advocate of materialism, Su Mo had always respected, but kept a distance away, from any talk about gods and ghosts.

There was nothing that could not be explained by science.

If there was something of the sort, that just meant that science had not reached a level where it could explain the phenomenon at that point.

As the only human on Earth who had already seen the fifth level of technology, while only being in the third level, Su Mo had enough of a "foundation" to analyze all the suspicious points from before.

"For now, what I need to find out is the real cause of Ma Fei's death and where exactly the world outside the ruins is."

"This includes whether the level 17 core refers to this town or whether it also encompasses the locations outside the town!"
