The "Golden Chamber Alliance" left by Zhao Kuangyin period triggered the battle for imperial power in Song Dynasty. Liu E, an orphan of Shu, met and fell in love with the third prince Zhao Heng during the war. After the rebellion of the king of Qin, the third son seized the official position and fought for the country, and they finally passed through difficulties and hardships. Liu E, with outstanding talent, has a close relationship with Zhou when dealing with political affairs, and is deeply dependent and trusted. Zhao Heng has lost several princes in succession, and succession to the throne is imminent. Due to their respective interests, the ministers of the DPRK and the clan forces fought against each other or secretly formed an alliance, and the Song Dynasty faced an unprecedented crisis. When Zhao Heng died, Injong was young and weak. In order to fulfill the last wish of the first emperor, Liu E presided over the political affairs, put an end to party struggles, built water conservancy projects, established welfare, properly solved the disputes and anxieties of neighboring ethnic groups, and boldly employed new talents such as Fan Zhongyan, Yan Shu and Su Xun, which laid a solid foundation for the "Renzong rule" after Renzong came to power for more than 40 years.
