I, a mere con artist, was unjustly imprisoned in Tantalus, the Abyssal Prison meant for the most nefarious of criminals, where I met a regressor.

But when I used my ability to read her mind, I found out that I was fated to die in a year…

and that the world would end 10 years later.

When the natural disasters come, the whole people travel through the wasteland world and face the challenge of death and survival!

Horrible acid rain, monstrous floods, sky-burning cities, global glaciers, super radiation…

No one is immune!

To survive, human beings can only build shelters and accept rounds of baptisms of natural disasters.

Fortunately, Somo awakened the doomsday survival system!

His refuge can be upgraded infinitely!

【Wooden Door】→【Iron Door】→【Alloy Gate】→…..

【Wooden Spear】→【Literwood Spear】→【Electromagnetic Spear】→…..

【Diesel generator】→【Bio generator】→【Thermoelectric generator】→…..

When everyone was rushing to prepare for the next disaster, Somo was already fully equipped and rampaged through the wasteland world.

“We’re still lighting the oil lamp, and they all use the refrigerator!”

“His refuge is said that the walls are tens of meters thick and it is the safest place in the world.”

“In my lifetime, I want to live in the Sushen Refuge for one day”
