At the end of the Eastern Han Dynasty, Emperor Lingdi's favorite concubine Wang Meiren gave birth to twins. Because of the persecution by Empress He, she claimed that she only gave birth to one son, Liu Xie, and the other son, Liu Ping, was secretly taken out and raised outside the palace. Eighteen years later, the princes fought against each other, and the puppet emperor Liu Xie was seriously ill. In order to save the Han Dynasty, which was about to collapse, he secretly summoned Liu Ping to return to the palace to replace him to revive the Han Dynasty. Liu Ping, who never knew his own life experience, and Sima Yi, who grew up with him, stepped into an unknown battlefield. When Cao's group's confidants Man Chong, Guo Jia and others launched an investigation around Liu Ping's life experience, Liu Ping resolved round after round of crises with the help of Empress Fu Shou and others. At the last moment, Liu Ping realized that the change of an era was irreversible, and he achieved the greatest victory without fighting. But Sima Yi, who had different political views and ruthless means, took a different path from him. Finally, after stabilizing the peace situation in the Central Plains, Liu Ping and Fu Shou practiced medicine and taught children among the people.
