Qin Xianglian didn't hear from Chen Shimei for a long time and took her son to Beijing to find her husband, but Chen Shimei refused to recognize her and sent Han Qi to kill her in the middle of the night. Han Qi couldn't bear to commit suicide, but Qin Xianglian was mistaken for the murderer. Chen Shimei commanded, Qin Xianglian was sent to the frontier, and your honour was ordered to kill her halfway. Luckily, she was saved by Zhan Zhao. Zhan Zhao went to his hometown in Chen Shimei to find the witness, the couple. On the way, Aunt Qi died by the killer's knife. Bao Zheng found a witness and wanted to convict Ma Xu. Both the princess and the queen mother quickly stopped her, but Bao Zheng refused to give in and sent Chen Shimei to the dragon head.
