During the Yongchang period of the Great Zhao Dynasty, Tianji Pavilion was brutally massacred. Jiang Wan fled to the south of the Yangtze River with the secret treasure Fengming Jade. She stayed incognito for ten years, hibernating as a musical instrument and secretly cultivating fortune-telling skills. But those who spy on the secrets of heaven will lose their lives.
In order to avoid being hunted by Xingyun Pavilion, she disguised herself as a man and headed north, accidentally entering Prince Yan's Mansion in the north and becoming an aide to the crown prince Xiao Jingheng. He appears to be a playboy, but in reality he has a hidden secret, and he is protected by the fact that she looks like the shadow of an old friend. The two experienced life and death together, and their love grew secretly.
Rumors spread in the court, and "the fate of the phoenix will harm the country" points directly to the north; Xiao Jingheng is actually the illegitimate son of the emperor, and is also the container of luck for the life-changing plan. The King of Yan was wronged, the three princes were forced into the palace, and Xingyun Pavilion launched the evil formation to restore the country. Jiang Wan sacrificed his life to save the people, but became blind; Xiao Jingheng was martyred in the capital, and his life and death are unknown.
Jiang Wan realized the true meaning of destiny in despair. The sound of the piano brought Xiao Jingheng back to life, the rebels were killed, and the new emperor ascended the throne. Xiao Jingheng's life experience was exposed, and the new emperor wanted to make him the emperor's younger brother. However, he and Jiang Wan had no intention of imperial power, so they retired to the world to protect peace.
