After Liu Bei's death, Zhuge Liang was edicted by Emperor Xian and became the de facto ruler of shu Han. In the first year of Jianxing, Zhuge Liang was given the title of Marquis of Wuxiang and began to open a government to govern affairs. Among his Xiangfu, there was a figure of extremely special status, although the official position was not large at that time, but he was unusually valued by Zhuge Liang, and this person was Fei Yi Fei Wenwei.
In 225 AD, Zhuge Liang won a great victory in the battle against Nanzhong and led his troops back to Chengdu. In order to welcome Zhuge Liang, the courtiers all went out of the city for dozens of miles to greet each other. But what was surprising was that Zhuge Liang beckoned in the car, called Fei Yi, who did not have a high official position, into the car, and talked with him for a long time. The courtiers were very surprised by this.
In the author's opinion, Fei Yi should be Zhuge Liang's secret pile specifically used to investigate hundreds of officials and even Liu Chan. With Fei Yi's help, even if Zhuge Liang went out on a campaign, the movement of the DPRK was still under control. In addition to monitoring hundreds of officials, Fei Yi also had a very important figure, that is, to coordinate the relationship between the two major pillars of Shu and Han, Wei Yan and Yang Yi.
Since the fall of Jingzhou and the defeat of Liu Bei's army in Yiling, the Shu Han talents have gradually shown a trend of withering, and Guan Yu, Zhang Fei, Ma Chao, Huang Zhong, Fa Zheng, and Ma Liang have either died in battle or from illness. During Liu Bei's time, Wei Yan, who was still a small character, gradually walked to the front of the stage. Wei Yan was strong in martial arts, good at raising soldiers, and proficient in formation, and was an irreplaceable strong general of the Shu Han Dynasty, and at the same time was also the right and left arm that Zhuge Liang relied on.
In the Battle of the Southern Expedition, Zhuge Liang discovered another talent, Yang Yi. This person is good at making plans, raising food and grass, and is very decisive in his work. The etiquette system in the military was arranged and inspected by Yang Yi. Zhuge Liang likes to do everything personally, but he can only let Yang Yi be alone
Although both Wei Yan and Yang Yi are talented, they both have serious flaws in their personalities. Wei Yan was arrogant and arrogant, with a rough personality, and it was difficult to get along with others; and Yang Yi's arrogance may still be above Wei Yan, and at the same time, he was narrow-minded and sharp-toothed, and he could not be forgiven. Therefore, in the process of working together, Yang Yi and Wei Yan were always in conflict.
On the one hand, Yang Yi often ridiculed Wei Yan with the advantage of his tongue. Wei Yan couldn't say anything about Yang Yi, so he revealed the face of a martial artist and drew his sword to kill people. Whenever this time comes, Fei Yi will definitely appear. On the surface, Fei Yi has an easy-going personality, talks humorously, and can get along with anyone, so his relationship with Wei Yan and Yang Yi is very good. Therefore, when the two clashed, Fei Yi could always save the scene. Therefore, when Zhuge Liang was alive, he could use wei Yan and Yang Yi as much as he could, thanks to Fei Yi's ability to save him.
Wei Yan and Yang Yi did not directly merge, relying on Fei Yi's mediation; on the other hand, the two were under Zhuge Liang's control and did not dare to make a big deal out of it. Therefore, as long as Zhuge Liang is alive, the two will not cause a big mess. But when Zhuge Liang died, the conflict between the two would surely endanger the stability of the Shu Han regime.
In this regard, even Eastern Wu Sun Quan saw it. At a banquet, Sun Quan once said to Fei Yi, who was an envoy:
"Tell Zhuge Cheng Xiang that your Wei Yan and Yang Yi are both pastoral villains, although they are a bit talented as chickens and dogs, but they can't get on the table after all." When Zhuge Cheng Xiang was alive, they might be very dissipated, and if Zhuge Cheng Xiang was gone, these two guys would inevitably rebel. So I want you to plan ahead! ”
For Sun Quan's words, Fei Yi naturally knew it. His deputy, Dong Hui, said:
"Now that Cao Wei is powerful, he has to appoint these two villains, and he can't throw away the oars because of the big storm on the river!"
The implication is that Zhuge Liang already knew that Wei Yan and Yang Yi were not good people, and using them was just a stopgap measure. Analyzed from a deeper level, Zhuge Liang was afraid that he had already made arrangements for his posthumous affairs, and there was no need for Sun Quan to bother at all.
During the Fifth Northern Expedition, Zhuge Liang died in Wuzhangyuan. Even at the time of his death, Zhuge Liang was still very clear in his mind that after his death, no one could compete with Sima Yi, so retreating was the best strategy. Therefore, he handed over the army to Yang Yi and ordered him to keep the secret and immediately lead the troops back to Chengdu. And the command was given to Jiang Wei. Wei Yan, the greatest official under Zhuge Liang, was completely ignored.
Zhuge Liang knew in his heart that after his death, Wei Yan would not obey his orders to retreat. As early as the first Northern Expedition, Wei Yan wanted to lead his troops alone and attack Chang'an with military adventures. However, Wei Yan's plan was rejected by the cautious Zhuge Liang. If he gave the military power to Wei Yan, he would surely go against Zhuge Liang's will and carry out his adventure plan. At his level, which is Sima Yi's opponent? Once it failed, Shu Han was in danger.
Therefore, Zhuge Liang handed over military power to Yang Yi. On the one hand, Yang Yi did not understand military affairs and would not continue the Northern Expedition because of greed; on the other hand, Yang Yi had a bad relationship with Wei Yan and would never cooperate with them. In this way, Wei Yan completely became an outcast. If Wei Yan obeyed Zhuge Liang's will, he might still be able to save his life. If he did not obey, all that awaited him was death.
Zhuge Liang died, and Yang Yi followed the leader's will and led the troops to retreat. And Wei Yan, as Zhuge Liang had expected, refused to retreat. Not only that, Wei Yan was also preparing to send troops to attack Yang Yi, and a fire was about to be staged. If a civil war breaks out, it will be taken advantage of by Cao Wei. At this moment, Fei Yi stood up.
First of all, Fei Yi pretended to be on Wei Yan's side and talked to him. To Wei Yan, who was furious, Fei Yi comforted: "I should go back to persuade Yang Changshi, who is a literary official and rarely knows about the military, so he will certainly not disobey his orders and continue the Northern Expedition with you." After stabilizing Wei Yan, Fei Yi grabbed a horse and fled.
When Yang Yi led the main force of the Shu army to withdraw, Wei Yan, who had been hit by Fei Yi's strategy of slowing down the army, was already unstoppable. So he led his soldiers to burn down the boardwalk and wanted to compete with Yang Yi. However, Wei Yan could no longer stand on the moral high ground and became the enemy of all The Shu army. Therefore, as long as Wang Ping's voice was raised, Wei Yan's subordinates scattered. Later, Wei Yan was forced to flee to Hanzhong with his son, but was eventually pursued and killed by Ma Dai.
After Wei Yan's death, Yang Yi, who maintained a smooth political transition, became a disaster again. As mentioned earlier, Yang Yi was conceited of his talents and was entrusted with heavy responsibilities by Zhuge Liang before his death. Because he was confident that he would definitely become Zhuge Liang's heir. However, to Yang Yi's surprise, Zhuge Liang appointed Jiang Huan to inherit his own phase, and Yang Yi was only assigned an idle post. Because Zhuge Liang understood that letting Yang Yi, who was narrow-minded and talented and immoral, be the prime minister would only cause disorder in the regime.
For such an arrangement, Yang Yi, who was completely ignored, complained and even scolded the world, and all his colleagues were unwilling to associate with him, only Fei Yi had a "good relationship" with him. One day, Fei Yi went to Yang Yi's house as a guest, who knew that Yang Yi said:
"When the past was killed, if I raised an army to take advantage of the Wei clan, I would rather be so evil!" It is irretrievable to regret. ”
That is to say, if the prime minister died, if I raised an army to surrender to the State of Wei, how could I fall into such a field as I am today? I regret it!
However, to Yang Yi's surprise, Fei Yi, the "little brother of confidant", did not hesitate to inform the empress dowager Liu Chan, and Yang Yi was deprived of all official positions and eventually died in exile.
It can be seen from this that although Zhuge Liang is known as the most righteous minister, he is at the same time full of power and scheming, and the city government is extremely deep. He left a Fei Yi behind to easily eliminate the two great plagues of Yang Yi and Wei Yan. Although Yang Yi and Wei Yan were both talented, without Zhuge Liang's restraint, it would only have a counterproductive effect. If it caused infighting between the Shu and Han Dynasties and led to the invasion of Wei and Wu, it would be more than worth the loss. Therefore, Zhuge Liang and Fei Yi calculated to eliminate the strange plot of the two and maintain the stability of the Shu Han for the next 30 years.
