My Doomsday Base Can Be Upgraded Without Limit

Meteorites fell, volcanoes erupted across the globe, the polar ice caps melted, sea levels surged, and volcanic ash blotted out the sky. The Ice Age descended...

“Upgrade the base walls!”

Concrete walls... thick steel walls... high-strength carbon-fiber walls... fully enclosed superalloy shell.

“Upgrade the base defenses!”

Ballistae... fully automatic machine guns... Gatling guns... rapid-fire automatic grenade cannons... laser cannons.

“Upgrade the base's power supply!”

Hand-cranked generators... diesel generator sets... biogas power plants... fission reactors... fusion reactors... stellar-scale nuclear reactors.

“Upgrade the base engine...”

Facing the hundred thousand people in his base, Yang Li waved his hand grandly. “We're setting out for the stars and beyond!”
