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..."

In the base camp, there were plenty of stronger, better warriors.

The seven of them were chosen not for their perseverance, physical condition, or combat powers.

At Su Mo's command, everyone raised their arms and exposed a mark on their wrists.

This was a unique logo, printed with a mini version of the Oreo statue. It looked funny and cute.

Activated by the idea, the mark glowed with a black light, bathing everyone in it.

In the darkness of the night, a storm started.

A small cyclone started to form around the snowy ground where the nine of them were standing, blowing bits of snow away.

The eight of them who appeared to be normal human beings started to melt, undergoing a huge transformation.

Su Mo's skin tightened rapidly, slowly becoming the color of dried tree bark and filled with textures.
