The carefree Bai Fengxi has to return to her other identity - Princess Xi Yun of the talented country, and then ascend the throne.

Whose hands will the world ultimately fall into? A piece of white jade, a white dress, and a kind of martial arts called "Phoenix Dance in Nine Heavens", this free-spirited woman swings between the江湖(jianghu) and her country; a piece of black jade, a black dress, and a calculating heart, this elegant man hesitates between the world and his loved ones.
