During the marriage between Yan and Qin three years ago, Xuechu, the legitimate princess of Qin, ran away from the marriage because she did not want to marry the long-sick prince of Yan. Linglong, the princess of the royal family who was married to the royal family, pretended to be Princess Lianbi and became a relative of the Yan Kingdom. Three years later, the Qin Dynasty was in chaos and the Yan army destroyed the Jin Dynasty. Xue Chu lived in the Yan State and became a palace maid. By chance, she was favored by the Yan State Crown Prince Murong Li and entered the East Palace. Just when Xue Chu thought that everything would be smooth sailing from now on, a woman named "Fu Yao" appeared as the direct princess of the Qin State.
