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..."

The price he had to pay in order to choose the billion-level update was the loss of the creation and training ground functions, as well as the possibility of a new hundred-million level function appearing.

Su Mo might not have said anything about this but, inside, he was filled with anticipation.

Thanks to the pivotal role he played in the situation on the wasteland, he was able to become the 'leader' of the human race within a very short period of time and become an important influence dictating the fate of Earth's humans.

This was a change that was recognized by the system.

As such, even without thinking about it, Su Mo was able to guess that this function update was either connected to the future of humankind or related to his future development!

[Host Su Mo, there are only thirty seconds remaining before the completion of the system update. Please be patient…]

Impressive Sight! Civilization Upgrade!
