Long Zu III: Hei Yue Zhi Chao

Lu Mingfei, Caesar, and Chu Zihang are sent far from Cassell College on a mission to Japan, where secrets tied to dragon blood point toward a threat greater than anything they have faced before. Their assignment quickly becomes a conflict with local powers that possess their own long history with the dragon lineage and little patience for outsiders.

There, Lu Mingfei meets Erii Uesugi, a girl isolated from the world whose blood carries a secret that makes her valuable to people willing to sacrifice anything. The closer the team comes to the truth behind the Black Moon Tide, the clearer it becomes that their mission is not merely another hunt, but a struggle surrounding the possible return of the White King.
