Apocalypse Survival: Starting with a Shelter

Scorching heat, an ice age, the disintegration of Earth, and relentless upgrades to a survival shelter.
With alternating extreme climate disasters, surface life faces extinction, and human civilization teeters on the brink of collapse.

Su Wu transmigrates to this parallel world, only to be immediately confronted by the threats of the apocalypse.

Fortunately, he obtains the Apocalypse Survival System. As long as he survives, he can endlessly advance technology, turning fantasy into reality.

A shelter complete with gardens, rice fields, forests, and ethereal, fairy-like companions.
Exoskeleton armor, powered mechs, mobile bases, and an integrated aerial-space autonomous mechanical fleet—

Starting from scratch, Su Wu constructs an underground shelter, gradually upgrading it step by step into a massive fortress capable of traversing the stars.
Eventually, in the vast expanse of space, he rebuilds the human empire.
