Cheon Yeo-Woon carries the shame of being born to a servant mother in a world obsessed with lineage and power.

What unfolds is a ruthless climb through a martial academy where every test could be his last. Armed with technology centuries ahead of its time, Cheon Yeo-Woon must outmaneuver rivals who were raised to crush him, uncover the mysteries surrounding his bloodline, and discover why his ancestor deemed him worth saving. As his power grows, so do the enemies around him—and the truth behind the Demonic Cult's deepest secrets begins to surface.
