I Inherited a Doomsday Floating City

When he woke up, Su Chen took the super-divine civilization system and traveled across time to become the lord of a floating city in the doomsday wasteland. What? The Hunter Corps is going to rebel. Well, the Magnetic Explosive Infantry and Ex Machina are going to attack them. The ignorant church encourages people to resist me, so don't blame me for showing any miracles! Can humans resist the monsters on the surface? It doesn't matter, let me start the practice for all the people! Since then, the floating city has become the master of the earth! A bottle of fifth-level genetic potion produced here can be exchanged for thousands of female slaves in a certain city-state. An ordinary skill secret book can be regarded as an ancient magic skill and worshiped by humans outside. An android Ex Machina can bulldoze a city-state tribe in an instant.
