At a night banquet in the palace, Zhen Huan quietly left the banquet because of the scene, but unexpectedly met Prince Guo at the Tonghua Terrace.Yunli told him about the life experience of his birth mother, Concubine Shu, full of sadness, lamenting the harshness of the world; Zhen Huan had a new crush on her, and she tactfully persuaded him, which made Yunli feel relieved.When Zhen Huan returned to the banquet, the palace maid reported that Cao Guiren's daughter Princess Wen Yi had vomited milk, which surprised the emperor and others.
Concubine Hua realized that the emperor loved Princess Wen Yi very much, so she hatched a plan and ordered Cao Guiren to take Wen Yi and raise her up. On the one hand, she wanted to win favor and show her virtue; on the other hand, it was convenient for him to further control and suppress Cao Guiren..Seeing her daughter suffering, Cao Qin silently complained about her suffering and secretly hated Concubine Hua.Wen Yi's illness worsened, and the emperor was worried. He stayed at Concubine Hua's palace day and night.
The imperial doctor suspected that Wen Yi's food was harmful to the stomach, and found out that the water chestnut soup the child ate had been replaced by tapioca flour. Zhen Huan was then suspected of poisoning.The emperor asked Zhen Huan if she could testify for her long absence from the banquet that night. Zhen Huan knew that the palace rules were strict, and if she said she was with Prince Guo, the crime would be even more serious. At a critical moment, Concubine Duan, who had been ill for a long time, came forward to testify for Zhen Huan, saving the day.Although the emperor had doubts, for the sake of public opinion, he gave the queen full authority to handle the matter. The queen ordered the princess's wet nurse and maid to be beaten.After this incident, Cao Guiren felt sad that her daughter was being used by Concubine Hua, and she felt betrayed.
