Henry, who traveled through a parallel world, was told that the "end of the world" would come in a week!

Meteorite impact, virus spread, ice age, various experts speculated that humans were about to face a catastrophe.

Fortunately, he was bound to the Doomsday Fortress System and had his own exclusive shelter. Every time he unlocked a layer of the fortress, he would get various black technologies!

First floor: light weapons production table, equipment production table, food production table

Second floor: heavy weapons production table, tactical throwing table, trap production table

Third floor: Chariot Technology Institute, Aviation Technology Institute

Fourth floor: Mechanical Vanguard Research Institute, Gene Enhancement Library

In addition, anything in the shelter can be upgraded infinitely!

When the super shelter composed of thousands of people was besieged by monsters and saw no sunlight, Henry was already fully armed, stepped over the corpses of monsters, and was alone in the supermarket worrying about choosing today's ingredients.
