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.

It took less than ten minutes for the entire carriage to be emptied, leaving enough space for two people to move around.

"What weapon do you normally use?"

"A weapon doesn't recognize allies. We should refrain from using them."

Su Mo knew that Feng Long was treating this extremely seriously because he sensed something similar about him with the Almighty Su from his memories.

He shook his head and quickly calmed himself down.
