The tyrant Pei Yanzhi insists on marrying Shen Zhiwei, the second daughter of the Shen family, who is called "brain-sick" by her father. After entering the palace, Shen Zhiwei made many jokes, but inadvertently helped Pei Yanzhi clean up the traitors in the court. She mistakenly gave the poison to the Queen Mother and gave the Dabu pill to Pei Yanzhi, which actually eliminated the hidden danger. Pei Yanzhi has long recognized Shen Zhiwei as his childhood benefactor, and he has indulged and protected her all the way. The two of them got along with each other in a funny way, from testing each other to falling in love with each other, and finally got married.
