When Wei Yan 10 defeated Ma Dai, even Wei Yan forced Pound and other military commanders of Cao Wei to go to Wei. At that time, xinmeile joint-stock company, which was famous in Cao Wei and was known as the second Lu Bu, was also cut off by Wei Yan. And if Wei Yan's own military literacy is not good enough, then he can't be sent by Liu Bei to guard Hanzhong, because this land is extremely important to Shu Han.
In addition to Wei Yan's excellent personal combat ability, Wei Yan's ability to organize troops and plan operations is not inferior to others. During his tenure, Hanzhong, where he was stationed, was impregnable. Even after Wei Yan was killed, the soldiers he left behind can still protect this place well. What he proposed in those days was the famous Woods Valley Miracle. Although it was not adopted by Zhuge Liang, in terms of its own strategy, it can be said that this strategy is absolutely unprecedented. Today, there are still people who fantasize that if Wei Yan's fantastic idea of the Meridian Valley is adopted by Zhuge Liang, can Shu Han successfully unify the Three Kingdoms?
But it is a pity that Wei Yan is good at commanding soldiers and brave himself, but his character is very proud, even Guan Yu, who was equally proud in those days, is not as good as him. It is for this reason that Yang Yi later murdered him.
