Apocalypse: My Shelter Has Unlimited Upgrades

Countless people transmigrated at once into an end-of-the-world survival game.

Floods, earthquakes, cold waves, radiation, acid rain: one natural disaster after another struck.

To stay alive, they had to keep building and upgrading their shelters.

That was when Lin Tian discovered that his System was different from everyone else's.

His System could upgrade without limit!

[? Wooden Door -> Stone Door -> Iron Door -> …]

[Wooden Pickaxe -> Iron Pickaxe -> Vibranium Pickaxe -> …]

[Natural Energy Generator -> Chemical Energy Generator -> Nuclear Power Generator -> …]

While everyone else was struggling to cope with the disasters,

Lin Tian's shelter was already packed with top-tier gear, and nothing could stop him!
