The queen mother pointed out that Mrs. Wen Shu's letter was only discovered at this moment ten years later. It must have been conspired by someone. Hongli decided to investigate thoroughly. Hongli confides his heart to the successor, and then points out the empress dowager's many doubts, every sentence points to the queen mother's problem, thinking that Niu Gulu's killing of the mother and seizing the son is the truth of the matter, and Hongli is shocked. Hailancha told Yingluo through Mingyu that the emperor was investigating the Queen Mother and advised her not to go to Shoukang Palace again. Hongli looked again at the picture of Chunhui sent by his servant Qian Zhengyuan. Hai Lancha found out that Qian Zhengyuan was the brother of Hongli's biological mother. Only then did Hongli understand the deep meaning of the picture of Chunhui. The queen mother fell ill, and came to visit her, but deliberately talked about the punishment of the queen mother's nephew, and admitted that Qian Zhengyuan fell off his horse and died because she planted the queen mother. The queen mother was so anxious that she suffered a stroke and fell down. Yingluo avoided the crowd and secretly invited Ye Tianshi to treat the Queen Mother. Lu Wanwan visited late at night and presented a secret recipe for treating stroke to win Yingluo's favor. The news of the Empress Dowager's serious illness spread to the Hall of Mental Cultivation. Hongli was determined to find out. He hurriedly visited Shoukang Palace, but was stopped by Lu Wanwan arranged by Wei Yingluo. Lu Wanwan gave Hongli a copy of Yuewei Thatched Cottage Notes, using a country story to imply that Mrs. Qian jumped off the cliff to protect Yongzheng and entrusted Hongli to the Queen Mother. Hongli was dubious.
