[6] Due to his family background and act of killing the servant, Liu already had a great reputation when he was in his early twenties.
Among them, Zheng Bao (郑宝) was the strongest and he wanted to force people living in Huainan to move to another prefecture.
At the camp, Liu persuaded Zheng's private army to surrender by analysing the situation for the soldiers.
"[15] In late 220 or early 221,[16] not long after Cao Pi crowned himself emperor, Meng Da defected to Wei and brought with him 4000 soldiers.
In addition, Cao Pi merged the three commanderies of Fangling, Shangyong and Xicheng (西城) to form a larger commandery, Xincheng (新城), and he appointed Meng Da as the Administrator (太守) of Xincheng and tasked him with defending Wei's southwestern border.
Liu Ye advised Cao Pi, "Meng Da is always looking out for rewards which are not rightfully his, and he is prone to schemes due to his talent.
[17] Also in 220, Liu Ye was made Palace Attendant (侍中) and bestowed the peerage of a Secondary Marquis (關內侯).
At that time, Cao Pi asked his court whether Liu Bei would avenge Guan Yu, who was killed during Sun Quan's attack on Jingzhou.
By then, Sun Quan was mobilising the power of the entire state of Wu to deal with the invasion, and he proclaimed himself a vassal to Cao Wei.
Liu Ye even suggested that Cao Pi take advantage of the situation to lead troops to attack Wu to avoid future troubles.
[20] Also, just before Cao Pi's death, he asked various officials, including Liu Ye, about Yang Fu.
