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..."

"This thing is incredible! It's almost like magic!"

Inside a room in the center of the hotel.

Feng Long squatted beside the window and excitedly operated an eight-inch screen in his hand.

Not far from him, a mini mechanical robot about 30 centimeters tall was making various movements following the commands on the screen.

The robot would jump when the jump command was pressed and even very humanistically bend its knees when landing to reduce the impact.

When the direction buttons were pressed, the robot would quickly probe forward, swing left or right, and even roll backward like a game character. It had basically zero delays in performing the command.

After a command to climb the table beside it was entered, the robot immediately executed the order and nimbly climbed onto the table within a few seconds.
