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..."

"The new design has separated the shelter into eight sections. You get one extra operations center if you compare it against Shen Yitian's design."

"Looks like the system understands me!"

Su Mo had a delighted expression on his face as he carefully gazed at the separated sections on the design plan.

"There might only be one television used for surveillance purposes in the current operations center, but I'll definitely bring in more powerful items in the future. The shelter will be upgraded according to this plan when the time comes for upgrades!"

Su Mo checked things several more times and ensured there was nothing else to add before launching the game panel.

Description: A shelter made entirely from stone. Exceptionally robust with good security, and it was unique in that it could keep out the moisture and retain warmth.
