Song Yude was worried that Song Yimeng and Nan Heng were very close, and urged Song Yimeng and Chu Guihong to get married as soon as possible. However, because Song Yimeng was worried about the divorce, he was unwilling to agree, so he planned to go to a chat banquet held in Beijing to discuss breaking the engagement with Chu Guihong.When Nan Heng learned that the two were about to get married, he was anxious and decided to design apart the two at the banquet.On the day of the banquet, Fugui helped Nan Heng deal with Chu Guihong, bringing the story of Chu Guihong's failure to explore Heyuan a few months ago and attack the camp onto the stage. This move actually aroused Song Yimeng's righteousness. She went to the stage in anger and decided to help Chu Guihong, but she turned out to be ugly in public.
Nan Heng was also unwilling to humiliate Chu Guihong for the defeat of Qianyu Army. Seeing Song Yimeng dead on the stage, she went up to relieve her siege without saying a word. However, Song Yimeng thought that Nan Heng did this because of the script mechanism.Chu Guihong took the stage, and a war song swept away the debauchery of the capital, and at the end of the banquet, he asked Song Yimeng to marry in public.Nan Heng was shocked. At this time, Concubine Gao came slowly and wanted to marry Song Yimeng for Nan Heng.This move caused conflicts among many parties present. In order to stand up for his cousin Chu Guihong, Nan Rui openly asked Concubine Gao to kill his mother.Nan Heng couldn't bear the humiliation of his mother's mother. He angrily defended that he had nothing to do with the queen's death, but he triggered Nan Rui to take action, and the two princes openly fought.The emperor was furious and issued an order to summon everyone to the palace to question, including % Song Yimeng.
