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..."

Thick fog engulfed the wilderness.

The night shrouded the earth and completely obscured the traces of biological activities during the day.

It was another sleepless night in the Hope Village as the news of Chen Shen and Li Hu was passed back to the villagers.

Six huge spotlights illuminated the skies in an instant, and the street lights of the village were switched to full power mode.

A series of harsh sirens began to echo through the village speakers that had never been used in the past.

The sound-asleep villagers were startled and subconsciously got out of their beds.

"Sh*t! It's a Level 1 danger alert!

Three long beeps and two short beeps.

Most villagers recognized the alert's rating from their previous drills.

There could only be one reason for the alert to sound on such an ordinary night!

The village had entered a critical life and death situation!
