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..."

During the day, Oreo sandwich cookie followed Su Chan to herd the yaks and sheep, only returning around four in the afternoon. Moore joined the infrastructure team, relying on his power to earn some extra pocket money for late-night snacks. Even Big Spark wasn't idle. After resting early in the morning, it would stroll over to the newly cleared vegetable fields in the village for guard duty, staying there until nightfall. Thus, after inspecting the recent developments across the territory and returning to the Underground Shelter, Su Mo found himself with some rare free time.
