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..."

Ai Jianfeng's theory was not hard to understand.

When electricity was first developed on Earth, because of the various limitations, scientists had to find a substance that could accommodate and transmit energy to perfectly solve the humans' energy shortage.

Centuries have passed, and those who pointed out the problem were replaced over and over again. The development of material science had also taken an enormous leap into space and exploration of other planets, yet the problem could still not be solved. Eventually, it progressed to a worse state.

Before the transmigration happened, energy was still an unsolved problem for those on Earth.

The energy problem was sustainable in Huaxia where it had maintained a stable cost. Even when there was an energy consumption limitation, the matter could be easily solved.

In the other regions beyond Huaxia, however, you would be able to notice the extreme energy shortage from the skyrocketing prices of energy!

This Feels Like Heaven Because I've Been Through Hell!
