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.

"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 observing for a while, Hou Tielong simply opened the door behind him and returned to the house after being upset by the noise.

A fully armed man hurriedly greeted him after seeing him enter the house.

"Tielong, all the supplies are ready to be transported away through the secret passage we dug out.

"Our men at San Yuan Hotel will be returning soon, and we can leave any time."

Hou Tielong's agitated emotions disappeared upon hearing the good news.

It was necessary for a bounty hunter to be well-informed.
