Hou Ning was initially decided, the new emperor Huo Jingheng (played by Wang Ruichang) chose to accept a virtuous concubine, and Yue Ling'er (played by Li Zixuan), the sister of Yue Chi (played by Xie Xingyang), the former prime minister of the former dynasty who had disappeared for two years, entered the palace to serve. Yue Chi, who loved his sister, couldn't bear to let his sister enter the palace to be angry. At the same time, because Huo Jingheng has recently paid a lot of attention to the people of the previous dynasty and the affairs of the previous dynasty, he was worried that Huo Jingheng would purge the old ministers of the old dynasty, so he decided to enter the palace for his sister to investigate the truth. However, all this was a conspiracy between Yue Ling'er and Huo Jingheng, and the concubine let Yue Chi enter the palace to help him re-enter the palace. Yue Chi escaped trouble with his intelligence in the palace, and Huo Jingheng took advantage of his uncle's dereliction of duty and other serial schemes to push Yue Chi, a capable minister of the world, to the position of right prime minister. Although the two had a disagreement due to the discord between the princess Jiang Yunqing (played by Gong Wanyi) of the previous dynasty, they took each other in the conspiracy of resisting the departed prince Yi Qingyun (played by Wang Jiahui) and solved internal and external troubles.
