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..."

"Oh Zeta, Zeta, you were such a good person! Ah no, I mean a good dragon!"

The matter conversion engine was dark and lustrous. Although all kinds of thick lines intermingled together on its surface, its high-tech aesthetic appearance was not lost. As Su Mo caressed it, he became more and more fond of it; the more he looked, the happier he was. His eyes brightened up as well.

The first time he killed Zeta, he received a silver treasure chest and obtained the blueprint design of the energy bike.

Su Mo had thought that he would only be able to manufacture it during the later stages of technology development on the wasteland. However, at that stage, there would not be too much use for a bicycle.

Yet it was with this design that the harsh conditions for unlocking the matter conversion engine were achieved!

The price of unlocking was naturally the energy bike blueprint design. It acted as a key, and disappeared forever after being consumed by the cube.
