The story starts off with Xiaoyanzi accidentally losing a child. The empress dowager is now increasingly unhappy with Xiaoyanzi, believing she is not ladylike to be Yongqi's wife, particularly in carrying on the family line. At the same time, Qing'er and Xiaoyanzi's brother, Xiao Jian, were also in love. But empress dowager dislike Xiao Jian, especially after when she finds that Xiaoyanzi and Xiao Jian's father was killed by Qianlong. She thinks that the siblings may want to kill Qianlong for revenge. Before she finds out this fact, they went to Chen's family, where she met Zhihua. The Dowager likes Zhihua more than Xiaoyanzi, and wants Zhihua to marry Yongqi. After returning to the imperial palace, the empress dowager makes a plan to separate Yongqi and Xiaoyanzi, Qing'er and Xiao Jian. She threatens them that she would kill Xiao Jian if Yongqi does not marry Zhihua, and requests that Zhihua should be wife and Xiaoyanzi should be a concubine. To save Xiao Jian's life, they accept the empress dowager's conditions and Xiao Jian is sent away. Yonqi marries Zhihua, as the empress dowager requests. The empress dowager also sends many servants to come and serve the couple. First, they pretend that they really love each other. However, Zhihua really loves Yongqi, and forces him to bathe with her, which angers Xiaoyanzi. Although Yongqi gives in and marries Zhihua, Zhihua remains a virgin after marrying Yongqi for quite a long time. But eventually, ErKang and Ziwei persuade Xiaoyanzi that Zhihua has the right to have a child of Yongqi. Xiaoyanzi, being convinced, forced Yongqi to enter Zhihua's room. Not long later, Zhihua is found pregnant. Not much time after the news, both Yongqi and Erkang volunteer to go into war with Burma. In the war, when Erkang fights with the eighth 'prince', who he finds that 'he', or rather 'she', is actually the eighth princess, Musha. Musha is attracted to Erkang, and plans to take him back to Burma. Musha disguises another soldier to look like Erkang to make the Qings think that Erkang is dead. After the war ends, Xiao Jian remains in YunNan, because he is suspicious about Erkang's death. Xiao Jian later discovers Erkang may not be dead and has been captured to Burma. Xiao Jian takes the news back to Yongqi, Xiaoyanzi, Ziwei, Qing'er in Beijing. The Group travels to Burma in order to rescue Erkang. They initially ask Qianlong to let them go to Burma to rescue Erkang, but Qianlong doubts the news and refuses to let them go. They resolve to go to Burma on their own by sneaking out of the palace. Xiaoyanzi wants to stay in YunNan, and she convinces Yongqi to stay with her. Zhihua hears their conversation and gets angry. Qianlong also asks to see the person who brought the news, Xiao Jian, but Xiao Jian refuses to see the emperor.
