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..."

"Thanks to the contributions of our ent allies, we were able to effortless obtain coal easily today and survive through this winter.

"This is a personal gift for Elder Zhu Ling, please do help me pass it to him!"

Su Mo took out the ten "heavenly fruits" that had been prepared in advance and handed them over with an overjoyed expression.

30 minutes ago, the Level 4 ent captain came to the basin's border and was surprised by the coal that was piled up on a small hill.

Until now, he was not able to figure out what means the basin used to accomplish such great achievements.

The ents were very simple, and if they could not figure it out, they would just forget about it. If they could not get through a corner, then they would just give up and leave it to their ent lord to figure it out!

They happily accepted the fruit from Su Mo's hand. The lead ent thanked him repeatedly and did not stay any longer.
