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..."

"F*ck, did someone light a fire in the shelter?"

A cold shiver raced down Su Mo's spine as he smelled the lingering scent of smoke in the bedroom, hearing what sounded like clanging sounds caused by stirring movements.

Su Mo, who had been fast asleep all this while, woke up instantly.

A split second later, Su Mo jumped up without thinking after realizing that the smell was indeed from firewood and quickly bolted toward the source of the smell.

A fire underground was different from one above-ground. If it blazed out of control and reached the explosives on the third floor... then an unimaginable "tragedy" would take place!

As Su Mo ran outside, thoughts flashed through his mind as he recalled the things he did yesterday before he went to bed.

Did he forget to turn off the fire after steaming the fruits?

Did the wood pile tip over into the fire?
