During the Five Dynasties and Ten Kingdoms period, there were turbulent wars. Small border countries formed marriages with each other to protect themselves. The Nanping State wanted to marry Princess Fengyi to Meng Tao, the Xiaoyao King of Later Shu. The entire Nanping Kingdom rejoiced over the marriage between the two countries. The King of Nanping sent the old minister Tie Wencheng and his maidservant to accompany the marriage. The spring breeze, summer rain, autumn frost, and winter snow escorted the marriage. Xiaoyao Wang Mengtao was afraid of losing his freedom in marriage, so he changed his name to Long Tao and ran away from marriage. Princess Fengyi also disguised herself as a man and escaped from the wedding party. General Yang Silu of Nanping Kingdom and minister Yin Quantong plot to usurp the throne and kill King Nanping to seize the throne. According to the tradition of King Nanping, he must have the national treasure "Lang Dao" to become king. Yang Silu believes that it must be Fengyi, so... What if Meng Tao's former lover is reborn?
