Wei Yan, it can be said that the last military general of the Shu Kingdom represented. After the death of the Five Tiger Generals, the military strength of the Shu state was greatly reduced. At the end of the Shu Kingdom, he single-handedly supported the army strength of the Shu State. However, despite this juncture, his superior Zhuge Liang still had distrust of him, saying that Wei Yan had an anti-bone, and sooner or later he would rebel. That Wei Yan was carrying such a big responsibility, but also subject to the suspicion of his superiors, why didn't he go to the State of Wei, with his position in the State of Shu and his own skills, he could also mix well in the State of Wei, so why didn't Wei Yan do this?
Wei Yan's strength
Wei Yan followed Liu Bei when he entered Sichuan, and fought countless battles in his life, and achieved great successes, in the first year of Zhang Wu, Liu Bei established the Shu Han Dynasty in Chengdu, and Wei Yan was also named the general of Zhenbei at this time. Later, Liu Bei died, Liu Chan ascended the throne, and Wei Yan was made a marquis. It can be said that Wei Yan has been treating him for so many years, and the Liu family has not treated him thinly, but Wei Yan also deserves these rewards. Wei Yan never apologized to the Liu family.
Therefore, even if Zhuge Liang said that he had an anti-bone, he still did not betray Shu Han. Even if the current situation is difficult, he will not rebel, one is to repay Liu Bei's kindness, the other is not to let Zhuge Liang's words come true, can not let his slander become a fact, then Zhuge Liang has a good reputation of clever calculations, and he himself is saddled with the ancient infamy of traitors. It's not worth it.
Another point is that at that time, the State of Shu was already at the end of the crossbow, and no matter how much it resisted, it would be swallowed up by the State of Wei, so whether Wei Yan surrendered himself or not, the State of Wei no longer cared. It was an enemy, Wei Guo didn't care, it was a friendly army, and Wei Guo didn't need it. Moreover, at this time, the State of Wei was no longer the domain of the Cao family, there were undercurrents surging everywhere, and the Sima family had been coveting it for a long time, and when he inserted it at this time, he would definitely be reduced to political cannon fodder. Wei Yan himself was okay with leading his troops to fight, and he didn't understand politics at all. Therefore, even if he arrived in the Wei Kingdom, he would not end up with a good ending. Wei Guo looked down on the betrayer even more, and directly cut himself just like he had cut Lü Bu in the first place.
Therefore, in summary, whether wei yan was for his own reputation or his own life, he would not betray the Shu state and defect to the wei state. So although the Shu kingdom was no longer able to do it, although Zhuge Liang did not trust himself and misunderstood himself. But you still have to stick to your heart, at least you can prove that you are not a rebel, and you can leave a good reputation for future generations.
