Death was a certainty for Cheon Yeo-un until the future literally crawled under his skin. As the illegitimate son of the Demonic Cult's High Priest, Yeo-un spent every waking moment dodging the poison and blades of his father’s six powerful wives. He was a prince in name only, a powerless boy destined to be a footnote in his half-siblings' rise to power. That all changes when a mysterious descendant from the future saves his life with a forbidden gift: an injection of cutting-edge nanomachines. Suddenly, Yeo-un has a cold, calculated artificial intelligence mapping his meridians, optimizing his movements, and reconstructing lost martial arts in the blink of an eye. The gates of the Mashin Academy are open, and while his brothers expect a lamb for the slaughter, they’re about to face a monster forged from blood and silicon. This isn't just about survival anymore; it is about a son’s burning vengeance and the ruthless quest to become the ultimate Lord of the Demonic Cult.
