Iljin Demonic Cult

He was the unrivaled tyrant who trampled over the martial world--Gucheon, the Supreme Lord of the Demonic Cult, feared across the orthodox sects as the Living Heavenly Demon. Leading his cult to dominate the peak of Murim, Gucheon became the symbol of terror itself. But during the final, brutal Great Demonic War, where all sects of Murim united against him, Gucheon was ultimately struck down-- not by warriors, but by an unknown force. Just when he thought it was the end... He opens his eyes-- not in the blood-soaked plains of Murim, but inside a frail, modern-day teenager's body! "What is this weird world?! Someone send me back!!" Now stranded in the modern era, the once-unstoppable demon lord must navigate a new jungle: high schools, city streets, and an unfamiliar world without qi or swords. Gucheon descends upon the modern world-- and a new era of chaos begins!
