Zhen Mi is a famous alluring beauty and the wife of Yuan Xi. In 204 AD, Cao Cao led an army to attack Yecheng. After Yuan Shao's defeat, they went straight to the palace. Yuan Shao's powerful officials sacrificed Zhen Mi for their gallantry. Both Cao Cao and Cao Pi fell in love with Zhen Mi at first sight. An angry Cao Cao sent Cao Pi to Nanpi. Zhen Mi was afraid that she would fall into Cao Cao's hands and was about to commit suicide, but by chance Cao Zhi took her down. After Zi Yan helped the two convey their friendship, the two gradually fell in love with each other. Soon after, Cao Pi returned to the city because of his military exploits. Cao Pi himself was very dark and ambitious, and he was affectionate and dedicated to Zhen Mi. The first thing he did when he returned to Yecheng was to ask Cao Cao to marry Zhen Mi as his wife. Knowing Cao Pi's ambition, Zhen Mi agreed to marry Cao Pi in order to help Cao Zhi become the heir, but it was conditional on the dispute between the two men. Under the advice of his concubine Guo Xiao and other powerful officials, Cao Pi could no longer bear the desire for power and chose to break his promise, and finally succeeded to the throne of King Wei, and secretly assassinated Cao Pi. Cao Pi denied that relatives killed each other, left a seven-step poem and went to Luoshui to live in seclusion
