Li Yihuan (played by Yang Zi) is a descendant of the Yongli court of the former Ming Dynasty. He grew up in Mingzhu Valley, where the old men of the former Ming Dynasty gathered. He learned martial arts from his masters together with Zhu Cixuan (Li Jianqing) (played by Mao Zijun), Xue Qingcheng (played by Shu Chang), Ye Mosheng (played by Han Chengyu), Fan Qianying (played by Sun Wei) and other senior brothers and sisters. After growing up, Yihuan and his group left Mingzhu Valley and tried to get close to Kangxi (played by Qin Junjie) at the instruction of their master, trying to find an opportunity to avenge their family hatred. Yihuan and the young Kangxi went from being happy enemies to being in love and finally having to turn against each other. Sincere feelings and family hatred became the biggest contradiction between them. The other boys and girls also experienced their own love, hatred and hatred while taking on the important tasks given by their teachers. Kangxi's idea of governing the country with benevolence and virtue finally moved Yihuan. She gave up her hatred and tried to persuade her friends not to cause wars and harm the people for personal hatred. In the end, Yi Huan decided to leave the palace, and Kangxi and her husband would forget each other in the world and remember each other in their hearts. Kangxi promised that he would be a wise ruler and eventually unify the hearts of the people, thus creating the prosperous Kangxi and Qianlong eras.
