At the beginning of the later Ning Dynasty, the new emperor Huo Jingheng (played by Wang Ruichang) selected a virtuous concubine. Yue Linger (played by Li Zixuan), the sister of the former prime minister Yue Chi (played by Xie Xingyang), who had been missing for two years, entered the palace to serve.Yue Chi, who was eager to love his sister, couldn't bear to be angry with her sister when she entered the palace.At the same time, because Huo Jingheng has paid much attention to the people of the previous dynasty and the affairs of the previous dynasty recently, he was worried that Huo Jingheng would cleanse the old ministers of the old dynasty, so he decided to enter the palace for his sister to investigate the reality and reality.However, all of this was conspired by Yue Ling'er and Huo Jingheng, who used the concubine to let Yue Chi enter the palace and help him re-enter the officialdom.Yue Chi escaped trouble with his talent in the palace, while Huo Jingheng took advantage of the series of plans such as the dereliction of duty, and pushed Yue Chi, a capable minister in governing the world, to the right prime minister step by step.Although the two of them had a rift due to the alienation of the former princess Jiang Yunqing (played by Gong Wanyi), they met with each other in the conspiracy of the rebellion against the prince Yi Qingyun (played by Wang Jiahui), and solved their internal and external troubles.
