Chinese-language version of Constantine. He is a sinner on a quest to subdue demons at the deity’s command, yet the devil intends to convert his loyalty for an imminent massacre.

Leaf seeks help from the Master exorcist Jay to save her mother. Jay is not a hired medium, nor does he profit from his work. He follows instructions drawn from a lottery box by a bird, which are commands from the child deity The Third Prince (san-tai-ze). Despite his countless exorcisms, Jay never benefits financially; his motivation is to atone for his sins.

He realizes this mission is connected to the Demon Mara and becomes anxious. The Third Prince has given Jay many Magic Weapons to combat evil, but they are running low. The impending battle marks the culmination of their agreement, and Jay’s sins will be reconciled. He recognizes that the challenge ahead is formidable, but as a sinner, he understands it’s time to seek redemption.
