The person who is called the queen of the demon is Zhao. When she was born, her parents left her on the side of the road because she was a girl. After three days, we can only take her back. When she grew up, she was called a dancer in the princess's family. Because of his outstanding figure, he was attracted by Emperor Han Chengdi and brought back to the palace. Later, she tried her best to frame the queen. After Emperor Han put her to death, she became a new queen, but she was still not satisfied and wanted to control state affairs.

At that time, Emperor Han Chengdi visited the Princess House and accidentally saw Zhao dancing. Emperor Han Chengdi was fascinated by Zhao Yanfei at once. After he was taken back to the palace, Emperor Han Chengdi didn't go to the court for three consecutive days, just to spend more time with Zhao. At that time, in order to stay young, Zhao used a medicine called Xiji Pill, but this medicine had a side effect, that is, it contained musk, which would lead to infertility if used for a long time.

However, Zhao thinks that the main reason why she can't get pregnant is not because she used Xiji pills, but because Han Dang married the emperor. So in order to consolidate her rights, she secretly brought many handsome men into the palace, hoping to have a son with them. However, it happened that Han Chengdi met him. He knew that Zhao was deceiving himself and turned away. Later, Zhao Hede, Zhao's sister, helped dissuade Emperor Han from changing his mind.

From then on, all those who reported the two sisters no longer believed that Han Chengdi would be directly executed, which made the two sisters more rampant in power and harem. Later, Emperor Han Chengdi rested in Zhao Hede's bedroom and suddenly died after waking up. Zhao Hede also directly committed suicide to apologize, while Zhao committed suicide after being directly demoted to a civilian.
