In the first year of Cao's reign, Liu Sheng accidentally beheaded Yan Liang and Wen Chou. In the fifth year of Cao's reign, Liu Sheng accidentally attacked Yecheng and robbed Luo Shen. In Cao Cao's tenth year, Liu Sheng accidentally leveled the grassland for Cao Cao, and the north had no worries. In Cao Pi's 20th year, Liu Sheng originally wanted to retire and be free and easy, but in the face of Cao Pi's pressing pressure, Liu Sheng decided not to bear it anymore! At this moment, Liu Sheng, who was the prince-consort, general, Taiwei, minister, governor of Hebei, and champion of the Wei Dynasty, looked at Cao Pi who was trembling on the throne and asked, why did your majesty rebel? … Cao Cao: After I die, if Zihuan is not talented, you can take my place!
