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..."

Within every actor, lies the ambition to become the director of that stage.

It was dusk at the time and Pei Shao had been summoned to the Underground Shelter. He was the first person from the entire Hope Village to be summoned to the shelter, so he was panicking!

Huge beads of sweat dripped audibly from his forehead onto the floor.

It was not because of the hot weather, but rather because Su Mo had a loaded rifle with its safety off beside him. That shocked him!

"Lea-leader, I guarantee you, no, I swear to God, I swear upon the Pei family's name that I, Pei Shao never betrayed you, ever."

"As for the mission of tracking the foreign races, I swear on my life that if I ever slacked off or ever betrayed you in any way, you can take my life as you wish!"

The Truth, Just Within The Cannon’s Firing Range!
