In a fantasy world where immortals and demons coexist, cultivation sects abound and the Demon Cult lies hidden in the shadows. The various factions scheme and fight openly and covertly over resources, cultivation techniques, and secret treasures. In ancient times, a mysterious green coffin appeared, containing powerful Dao patterns and a world-shaking secret. Its arrival unleashed a bloody storm. The coffin later vanished, but its legend has been passed down through the cultivation world for a thousand years.
