The full story
Chapter 1: Ashes and Oaths
Chapter 1 opens in the Heavenly Demon Cult of Mount Cheonma, where the modern otaku turned Heavenly Demon can no longer ignore the storm gathering on the horizon. What begins as a quiet morning turns tense the moment word arrives that a masked envoy has crossed into forbidden territory.
the modern otaku turned Heavenly Demon draws on genre-savvy knowledge of every technique’s counter, and for the first time the true scale of that gift becomes clear. Those who once dismissed the hero as ordinary are forced to reconsider — power like this does not appear by accident, and everyone can feel that the balance has shifted.
Standing in the way is the elders who suspect their leader is an impostor, whose ambitions have only grown sharper. Their confrontation is less about brute force and more about wills: two people who understand exactly what the other is willing to sacrifice. By the final page, a line has been drawn that cannot be uncrossed.
