Whether the perpetrators be Pirates or Marines, all shall be brought to justice!

In the wasteland world, humans who have reached the age of eighteen will receive a city seed, thus becoming a city lord. Once planted, they can choose one of three cities: land, sea, or air.

A city is born of its lord, and it dies with the death of its lord. Once the city is destroyed, the lord will become a citizen without a city.

The city can move, fight, and continuously upgrade; it is both a super-powerful force and a place for humanity to survive in the wasteland.

Xiang Yang has been reborn and returned, unlocking a hidden option: Attack the City.

In the wasteland, there are no superpowers, no bloodlines; only the steel behemoths known as cities are the hope for the continuation of human civilization.

This is a story about a man who leads his own city across a post-apocalyptic wasteland.
