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..."

"He didn't have a lot, but everything he owned were essentials. Compared to the likes of Huang Biao, Kento Maeda was a very qualified enemy!"

Su Mo placed Kento Maeda's core down and casually waved his hands, accessing his storage space.

In the corner laid two black, polished pistols.

"I got too accustomed to Kento Maeda's storage space. Now that I'm in mine, it suddenly feels like it has grown a lot bigger!"

Su Mo was a little wistful as he grabbed the pistols with his mind and brought them out.

The two pistols looked exactly the same. They were probably acquired from the same source.

"These guns looked strange, but had a familiar air around them. They were probably produced in batches and obtained from treasure chests, I think?"

Switching the guns' safety on, Su Mo held the left gun in his hands and carefully examined it.

Kento Maeda and the big man's guns did not exist on Earth.
