It has been three hundred years since magic disappeared from the Divine Land. Chen Xing is the last Great Exorcist - a young man with a tenuous grip on magic whose life is destined to end on his twentieth birthday. As whispers about the return of the demonic entity known as Mara echo across the land, Chen Xing is burdened with a daunting task: to seek out his fated counterpart, the Protector Martial God, and together, to save the world. Enter Xiang Shu, a condemned man with a haunted past. Accused of unspeakable atrocities, Xiang Shu is an enigma - handsome, skilled, and facing execution for crimes he claims he didn't commit. As their destinies intertwine, Chen Xing and Xiang Shu embark together on a journey where the salvation of everything they know hangs in the balance.
