(This is probably the most tacky plot synopsis): Ling Cangxing, the eldest son of the Ling Kingdom, met a singer named Yueyu at an accidental banquet. The bizarre death of the lieutenant made him doubt her and the organization behind her, which involved the ulterior secrets of the Yusi family's annihilation many years ago when they were fighting for the throne, as well as the last orphan Teruki, how powerful the Scroll of the World is... Everything is different from what he imagined.
