In this thrilling high fantasy adventure set in ancient China, a naive young man must join hands with an unlucky general to protect the mortal world from an evil spirit king.

In the mystical Taihang Mountains, where magic flows and powerful yao roam, Hongjun has grown up sheltered from the human world. A half-yao himself, he’s never had reason to leave—until the mountain’s ruler sends him on a dangerous mission: hide his true nature and join the Great Tang Department of Demonic Exorcism in Chang’an.

Upon arriving in the bustling capital, Hongjun meets Li Jinglong, a luckless soldier with no spiritual power tasked with leading a team of extraordinary exorcists. Together, they and their enigmatic companions must face the dark forces threatening the city. But as a bond begins to bloom between Hongjun and Li Jinglong, Hongjun wonders: Can he trust Li Jinglong with the truth of who—and what—he is?
