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..."

As the 75th leader of the Expeditionary Army, Su Deben had seen stronger, more powerful weapons equipped on even more terrifying vessels.

However, it was exactly because he was familiar with such things that he knew in depth what it took and what it represented, that someone had managed to create such a monster in merely 15 days.

"Su Mo, you discovered those Old Era Technologies on the wasteland?"

Su Mo, who was still communicating with Hope One's OS via the Bluetooth headset was stunned. "Old Era Technology? What's that?"
