Returner Created the First Mecha System

After the Dragon Disciples revived the dragons, the world fell into a catastrophic state. The dragons destroyed half of the world.

Jaxon fought with the rest of the Subjugation Company, continuing to sweep the dragons, leaving only one—the formidable last dragon. They fought it but unfortunately failed, resulting in their deaths, with Jaxon being the sole survivor, thrown back into the past.

He expected the looming threat of dragons and sought to stop their revival. Upon his return, he gained a mysterious ability from an artifact, becoming something called the Assimilation System. With it, he aimed to save the world once more, while uncovering his potential and creating a giant weapon to fight dragons and monsters—a colossal metal humanoid called Mecha.

Determined, Jaxon masters the gifts of his ability to create Mecha, intending to aid him reach his goal.

In a world where gadgets, artifacts, magic, and cultivation intertwined, Jaxon’s journey ended up creating the greatest legacy on land—the Mecha System.
