In the Romance of the Three Kingdoms, Zhuge Liang died of illness in Wuzhangyuan, and before his death, Zhuge Liang believed that the shu Han army generals were scarce, and no one but himself could provoke The Great Liang to be alone, let alone be the opponent of Sima Yi of the Wei army. Therefore, he hoped to slowly withdraw his troops after his death, retain his strength, and retain his strength in order to go out to attack the State of Wei in the future.

Zhuge Liang's actions aroused the dissatisfaction of Wei Yan, a general of the Shu army, who believed that "han thieves are not two sides, and Wang Ye is not biased", and that Wei Daye should not give up completely because Zhuge Liang died, and it was difficult to lead tens of thousands of troops out of the rugged Shu Road to come out and go back once without making a single achievement, and then he would have to make a hard effort to come out to fight in the future. Wei Yan expressed his willingness to stay and persist in resisting the Wei army, refusing to carry out Zhuge Liang's order to slowly withdraw.
At this time, his colleagues will blow up mao and not to do it, not to mention that the soldiers take obedience to orders as their duty, let you retreat even if there is a golden mountain in front of you, you must resolutely implement the retreat order and not covet these external things, not to mention that Shu Han has been poor for many years under the leadership of the ancestor Liu Bei and Zhuge Liang, a good country of heavenly palaces has beaten the people's livelihood and exhausted financial resources, and everyone can't stand it for a long time, so the powerful figure Zhuge Liang dies and everyone simply returns to each home, and the dangers of Yizhou are passed and the Hanzhong fortress is good. Hurry up the development of people's livelihood and recuperation to accumulate wealth.
At this time, Wei Yan was guilty of muttering, he thought that these teammates were deceiving themselves, and they took advantage of the fact that they were alone and were not with Xiang Xiang, and these people concealed and tampered with Xiang Xiang's last words before his death. Why did Wei Yan think so? Here's why:
1. At this time, Wei Yan was already the second most important person in the Shu Han army, and if Zhuge Liang was the marshal of the Shu Kingdom during the Northern Expedition, then he Wei Yan was the deputy marshal of the Conquest. Now that the Grand Marshal is sick and dead, whether it is talking about seniority, attacking cities and plundering land, or talking about military achievements, wei Yan should properly take over Zhuge Liang's post, when will it be Yang Yi's turn to lead the three armies?
2. The Northern Expedition was the basic policy of the Shu Han Dynasty. Because the world was originally the Jiangshan of the Liu family's Han Dynasty, it was only because Cao Wei usurped the Han Dynasty, and after Liu Bei seized Yizhou, in order to show that the Han Dynasty had not perished, he established a local government in a corner to oppose the usurpers. That is to say, the local regime of the Shu Han Dynasty has no legitimacy without the Northern Expedition, and it cannot be said that Zhuge Liang will not go north once he dies, right? Besides, when Zhuge Liang was alive, he belonged to this village and shouted the Northern Expedition the most urgently, and as soon as he died, this basic national policy was shelved.
Of course, the "Romance of the Three Kingdoms" said that Wei Yan had a backbone, and Han Xuan, the old boss who used to be in Changsha Pit, surrendered to Liu Bei and sacrificed the city, and this kind of employee who ate inside and outside was very unpopular. Liu Bei and Zhuge Liang could still hold Wei Yan down while they were alive, what if they died? Even if this brother does not oppose the water, he must not let go of the self-pit dead Shu Han? Since this big pit could not be left behind, it could only be killed quickly to avoid being hot.
Moreover, Wei Yan was originally from the military, and it was inevitable that some merits in marching and fighting would inevitably be inflated, and no one would inevitably look down on him after a long time. Especially Yang Yi, Wei Yan once scolded Yang Yi in public, a big man. Since Wei Yan told others to lose their share, then don't blame people like Yang Yi for not being able to tolerate it. When Zhuge Liang was alive, he could still calm down the contradictions under his hands and protect Wei Yan, a love general, but after Xiang Xiang died, who would protect this person whose popularity was lost to the point of having no pants left?
As for Wei Yan really wanting to rebel, everything must have a purpose. He was also a powerful general in the Shu Han army, and if he surrendered to Cao Wei, he could take advantage of the opportunity to cover the retreat of the army and run to Cao Wei's territory to surrender his weapons to Sima Yi. Moreover, Cao Wei's talent is far better than That of Shu Han, why did Wei Yan be a chicken head in Shu Han and be a phoenix tail in Cao Wei? Moreover, if a descendant throws himself into the enemy camp, the other party must be hesitant to use you cautiously, doesn't Wei Yan know?
Unfortunately, When Wei Yan withdrew his troops, he ran too fast, and immediately after shaking off Yang Yi, he burned the boardwalk to cut off Yang Yi's way back, and finally the two sides sued each other for rebellion. At this time, the opportunity to examine the character of the examination arrived, and Liu Chan, the lord of the Shu Dynasty, watched the recital to seek the opinions of Jiang Huan and other ministers, and many people thought that Wei Yan's threat was greater, after all, a military general led his troops to retreat into Beijing and burned the retreat path of his teammates, how to look at it is not like a good stubble. In this way, Wei Yan's rebellion was established, and his three tribes were destroyed, Wei Yan was killed by his subordinates (some say it is Ma Dai), and Yang Yi saw Wei Yan's head and scolded him as a "dog slave" to vent his anger. Of course, Yang Yi did not get rewards and reuse after the fact, complained too much in private, and was killed by the Shu Hou Lord after he knew about it.
