Emperor Zhao Qian unexpectedly discovered that his son was not his own biological son, but the result of an affair between a noble concubine and her younger brother Zhao Yan. He wanted to confuse his bloodline and seize the throne. Faced with the betrayal of two close relatives, Zhao Qian pretended not to know and willingly raised their son as the crown prince, and abdicated the throne with the crown prince. At the grand ceremony of abdication, the Noble Consort, Zhao Yan, and the Crown Prince forced the palace to reveal the truth. Faced with their betrayal, Zhao Qian was extremely angry and laughed back, giving them a gift that had been prepared for more than 20 years. Zhao Qian raised his own son, Prince Zhen, outside the palace for the purpose of defeating Zhao Yan and others during the grand ceremony of abdication. Zhao Yan and others questioned the identity of Prince Zhen and forced Zhao Qian to confess his blood. The identity of Prince Zhen was confirmed, and Zhao Yan and others were all dealt with. Zhao Qian learned that Zhao Yan and other party members had committed evil deeds, causing hardship for the people, so he secretly visited and dealt with corrupt officials, bringing peace to the world
