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 warm sun of the winter morning could not raise the temperature to the warmth of summer.

Despite the weather in the basin finally turning clear today, the temperature remained at around -6 degrees between six and seven o'clock in the morning, and the apparent temperature was around zero degrees.

Seeing that most of the villagers who came to greet him began to sneeze due to the cold, Su Mo quickly ended his sentimentalism and returned to the shelter.

He pushed open the familiar door and breathed in the familiar scent of the shelter.

The Earth Tiger, King Kong, and the two rotary tillers parked in the garage had vanished.

The workshop was replaced with a heavy machinery workspace.

The partition they had built from the blueprint and the wall used for keeping tools had been demolished, and the room had been evenly divided from the middle.
