Everyone went to the Summer Palace to escape the summer heat. The emperor had to take Concubine Hua with him to the palace because of Nian Gengyao's power and status and old love. Guojun Wang Yunli responded to the imperial edict and entered the palace to accompany the emperor to shoot arrows for fun. His superb archery skills with one arrow and two pigeons aroused taboos in the emperor's heart for many years. Yunli sensed the emperor's dissatisfaction and doubts, and immediately stated that he would live in the world like a low profile and would definitely stay away from the government. Zhen Huan went to accompany the emperor, Cao Guiren took the opportunity to sow discord, implying that the emperor pretended to be the king of Guojun when he met Zhen Huan that day, which might arouse Zhen Huan's admiration for Yunli, not the emperor himself.

The suspicious emperor immediately had a grudge against Zhen Huan, and asked Zhen Huan when she had feelings for him. Zhen Huan cleverly dealt with it on the grounds that the Yu family bullied the emperor to make a rescue. Mei Zhuang had a favor and no pregnancy, and felt helpless, so he summoned his fellow countryman—the imperial physician Liu Yi to ask for the secret formula for conceiving a boy. Zhen Huan warned Mei Zhuang to be cautious, and Mei Zhuang reassured Zhen Huan that there was nothing wrong with Liu Huan being her fellow countryman. Coinciding with Princess Wen Yi's first birthday, the queen is ready to take care of it. Cao Guiren hosted a banquet and invited Zhen Huan, Meizhuang and others. During the banquet, Meizhuang was nauseated and vomited. Everyone thought that she was pregnant, and the emperor was overjoyed. The imperial physician Liu Huan confirmed on the spot that Mei Zhuang was more than a month pregnant, and the queen took care of Mei Zhuang to let her have a baby with peace of mind.
