When the Wasteland Era arrived, Xu Zhengyang was fortunate to obtain the Apocalypse Survival System one year in advance. Starting from scratch, he secretly built a Supreme Sanctuary beneath his home!

Biochemical crisis!
Radioactive wastelands!
A new Ice Age!
…
No matter what kind of catastrophe unfolds outside, Xu Zhengyang's sanctuary remains at a constant, spring-like temperature.

A starch manufacturing plant continuously converts carbon dioxide into food.

A vertical farm produces an endless supply of fresh fruits and vegetables.

An AI-powered automation facility runs 24/7, manufacturing engineering robots, power armor, and swarms of autonomous drones.


Starting from nothing, Xu Zhengyang builds a fortress capable of withstanding any disaster. As the upgrades continue, his sanctuary evolves into a planetary fortress—capable of sailing through the endless cosmos!
