Summary of the story: It is well known in the capital that Murong Heng of the Zhenbei Palace is a dandy prince who has no knowledge and skills and spends all his time in sensuality. He fights chickens and lackeys, spends money like water, and is the most reliable chess piece in the eyes of the emperor. Until a secret order came out, he was ordered by his father to secretly protect Su Wanqing, the daughter of the current prime minister. This Miss Su holds a shocking secret and is the focus of competition among all parties. In the ridiculous name of a pursuer, Murong Heng became a messenger, dealing with conspiracies, open guns and secret arrows. When the layers of disguise are peeled off, his real edge is revealed beneath the dandyism. He discovered that this protection was not only related to his family, country, and world, but also related to his own heart.
