Sixteen years ago, Qi soldiers raided the palace of the Xia Dynasty Emperor. The palace concubines surrounded the imperial daughter Yao'er and fled and disappeared. Since then, there has been no news about the mother and daughter, leaving only the royal family secrets of "a pearl in troubled times". Sixteen years later, as the Xia Dynasty's national power grew stronger, the current emperor was searching for his lost sister. Prince Helian Zhaoming also hoped to find this mysterious princess. In Yangcheng, three completely different figures are all vaguely related to the identity of "Yao'er": she is Su Yao, the prime minister's legitimate daughter who came from time to time and conformed to the setting of the paper man. She is smart and cunning but often shows off her otherworldly edge; Chu Feiyang, a genius doctor who wears men's clothing and travels around the world, has good hands and kind hearts but hides his red makeup and carries a sword to the end of the world; Liu Jingning, a young girl who comes from a small town in the northwest border and goes to Beijing to find her relatives, is simple and pure, but the confusion of the past is hidden in her eyes.
At the same time, Qin Yu, the number one scholar, Gu Yanzhi, the direct son of the Grand Tutor, and Xiao Ce, the young general, have intersections with the three women, either because of disputes in the court, their encounters in the rivers and lakes, or because of the border wars. In the process of exploring the truth, they are involved in the whirlpool of royal secrets, palace changes, and mysteries of their life experiences. Three lives, three identities, the fate of five young men and women are closely intertwined. Who is the real eldest princess of the Xia Dynasty? Under the dust of troubled times, the truth and love, hatred and hatred are slowly unfolding.
