On the continent of Drea, the once-prestigious Sermine family faces ruin after the disappearance of the father and brothers. The youngest son, Ri Yun, is captured by the powerful Paton family, suffers torture, and dies. Instead of passing on, he awakens in Adeon the endless battleground—an afterlife or “divine playground” where countless players die seeking power. There, Ri Yun becomes the Master Player “Ghost King,” mastering assassin, necromancer, and ghost professions, eventually challenging a divine creature. After being defeated and dying again, his story isn’t over. Ri Yun is reborn at age 12, back in reality but now possessing all his player powers. Determined to prevent his family’s downfall and reclaim everything lost, he transforms the real world into his personal game field. His first goal: bloody revenge against Paton, the rival family that ruined and killed him.
