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..."

It was 1.38 am on Day 55 of the wasteland calendar.

Hope One looked like a graceful "dancer" as it slowly sailed across the quiet seas.

The ship's current traveling speed was deliberately set to six knots. Even untrained soldiers on rafts could easily catch up to it.

Besides Moore, who was resting alone in the main gun turret, everyone else, including Big Spark and Little Spark, was inside the bridge.

Su Mo still had the Simba onesie on, and he pretended to be asleep in his seat. However, the OS constantly sent him messages through his Bluetooth earphones from time to time, ensuring he would never miss any important information.

[New life form has been spotted 49 kilometers southwest of Hope One. Based on its movement trajectory, it is highly suspected that it is an enemy. Captain Su Mo, please be on standby!]
