The Lonely City of Wanta: I Rely on Infrastructure to Protect My Territory in the Apocalypse

This alien world is called [Broken World Wasteland], and it is a desperate continent formed after countless planes were shattered and spliced ​​together. The entire continent is shrouded in black mist, and alien beasts, aberrant monsters, and void invaders are born in the black mist. All human survivors can only rely on the foundation of the realm tower to survive. The realm tower foundation is the core of special infrastructure left over from the origin of the world. Each human territory is based on a main tower, which can unlock and build various functional buildings. If the building is not destroyed, the territory will not be destroyed; if the main tower is not destroyed, the human race will not die.
