The world has been decided for the first time, and the Central Plains is unified. Leng Xingchen, the new leader of the largest gang in the Central Plains, forcibly marries Shen Zixin, the leader of the North Hall. Shen Zixin agrees on the surface but secretly plans to escape on the wedding night and travels to the Western Regions. By chance, he saves the Turkic prince who is being hunted. The two share weal and woe along the way and develop a secret love. After returning to the Turkic palace, facing the coup in the Turkic palace, the Turkic prince had to marry the princess of the Central Plains dynasty to protect himself. Shen Zixin fled the royal city and rescued Li Laosan, the killer who was chasing the prince. She persuaded him to change his ways and taught him the art of war and the art of concealing armor. Five years later, the Turkic prince ascended to the throne of Khan, found Shen Zixin, and married her into the palace as a concubine. Shen Zixin followed Khan back to the palace for love, but found that Khan was no longer the innocent-hearted man he once was, and seemed to be hiding a huge conspiracy.
