[Post-apocalyptic + reborn + limitless fortress upgrades + ruthless protagonist + cutting-edge technology]
A solar storm destroys civilization, ushering in an age of ice. Chen Mo is shoved into a blizzard by his own brother. When he opens his eyes, he has been reborn thirty days before the disaster.
This time, he is bound to the [Master Doomsday Craftsman] System.
While everyone else scavenges for food among the ruins, his fortress has already been upgraded into a war stronghold, with its own power generation, synthesized food, and fully automated defenses.
When his enemies arrive with their men to seize it, they discover they can't even reach the front gate. It's nothing less than a mobile arsenal.
But when the mysterious "Hunters" come knocking, and so-called "shelters" turn out to be cages for sorting people, Chen Mo finally realizes...
This apocalypse is actually a human-made breeding ground for raising Gu.
Then watch closely: my fortress will crush every conspiracy and become the one and only divine throne of the new era.
Reborn in the apocalypse, my fortress can be upgraded without limit. Before long, it grew into humanity's last royal city.
