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..."

After a brief introduction, Guan Yuan took down an AK rifle that was hung on the wall.

The rifle she took out was completely identical to an AK rifle apart from it not having a bullet cartridge and an auxiliary aiming scope clamped above the gun.

"Here, you can go ahead and try it. It's really easy to use!"

Guan Yuan switched on the auxiliary aiming scope and handed it to Su Mo after a buzzing sound.

Su Mo was extremely curious, and he immediately brought the scope closer to his eyes to look through it.

"Woah, this thing is really interesting!"

It was similar to a scope in a shooting game.

Feng Mengyue, who could be seen through the scope, radiated a yellow fluorescence light around her body.

Additionally, there was also a line of small parameters in the upper right corner, which roughly estimated for the user how much the riffle's muzzle had to be raised or moved to hit the target.
