Adrian was the star disciple of the prestigious Crimson Dawn Sect—until the day his own master, Victoria, drove a blade through his heart. His crime? Trying to stop his corrupted junior brother Sebastian from falling to darkness. But death wasn't the end. Reborn with memories intact, Adrian wants nothing more than to disappear and live quietly. Instead, he finds himself imprisoned in the sect's most dreaded location: the Forbidden Grounds. There, he awakens an incredible power—a mysterious system that grows stronger with each challenge he faces. Sebastian, now revealed as the Demon Prince, will stop at nothing to claim Adrian's legendary Divine Bone. As his demonic identity slowly unravels, the sect that once called Adrian family realizes the terrible mistake they've made. Now Adrian must choose: Will he forgive those who betrayed him, or will his newfound power make him the very thing they once feared?
