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..."

An idea was put forward, but whether it succeeded would require significant trials.

Su Wei was left alone to match the code in the virtual reality and study how to adapt to their requirements.

Su Mo and Ai Jianfeng exited the virtual reality and went back to the workshop to sit down.

A large laboratory for everyone's research had not been established yet. Even the blueprints have not even begun.

The place they called the workshop was in fact a prefabricated room that was previously vacant. It was separated by a simple wooden board, giving all the scientific researchers an independent space.

Ai Jianfeng's entire activity area added up to only 30 square meters. Except for the bed, the machines, and the bedside cabinet with books, it was merely enough for three or four people to sit down and talk.

Any more than that, and they would have to go to the larger conference room in the middle for discussion.

Day Two, the Happiness of an Ordinary Person!
