The two great powers of Cao Wei were at war, saying that they were at war, but neither side moved, but in fact, both sides had ghost ideas. Sima Yi's side, although on the surface, seemed to be indifferent to the various provocations of the Shu army. However, Sima Yi sent spies to keep a close eye on Zhuge Liang and observe his every move. When I heard that Zhuge Liang had to personally inquire into all major and minor matters in the Shu military camp, and there was very little food, and there were countless worries. He began to judge that the last pillar of the Shu kingdom had not lived long, and he was even more determined in his thinking, holding still and waiting for the Shu army to strife itself.
Sure enough, three months later, this top pillar of the Shu state fell ill and finally died of illness in the Wuzhangyuan army. Zhuge Liang was also worthy of being a military master, and before he died, he had already thought of a retreat for the Shu army. After his death, Jiang Wei and others blocked the news of his death, and only ordered the army to slowly retreat and began to prepare for retreat.
Sima Yi, who was aware of the withdrawal of the Shu army, felt that Zhuge Liang was dead at this time. Immediately leading the Wei army to pursue this army that began to prepare for retreat, what Sima Yi did not expect was that for his pursuit and killing, the Shu army did not panic and did not panic, very calmly turned the rear army into a front army, turned the entire army around, and lightly dealt with the Wei army's pursuit and killing. Sensing the atmosphere in the Shu army, Sima Yi began to doubt his own assumptions. At this time, Jiang Wei pushed out the dummy of Mr. Kong Ming, who had been prepared before, from the army, and saw the appearance of the old opponent, which completely disrupted Sima Yi's position. He resolutely ordered the army to retreat, and in this way, the last elite force of the Shu army fled back to the country, but Zhuge Liang, the towering tree, could not return.
It is said that Sima Yi's talent could easily capture the Shu state, but after his old enemy Zhuge Liang died, he not only did not attack the Shu state, but also did not attack the Shu army for more than a decade.
Originally, after zhuge Liang's fifth army left Qishan, Sima Yi at this time was already in a high position of authority in the army. Soon after, the emperor of the State of Wei also passed away, and he was left alone with Sima Yi and another person. At this time, Sima Yi had been completely caught up in the political turmoil of the State of Wei, and now the State of Wei was divided into two parties, one was the old ancestor of the Cao clan who followed Cao Shuang, and the other was Sima Yi's disciple. Because of his jealousy of Sima Yi, Cao Mou designed a bright rise and fall for Sima Yi. Feng Sima Yi served as the teacher of the little emperor as a lieutenant, and although he seemed to have unlimited scenery at this time, he had already been deprived of all the military power in his hands by Cao Shuang's plan.
Sima Yi, who had lost his military power, could be said to have no means of defense, and in desperation, Sima Yi had to pretend to be ill to protect himself, and at the same time, he was also looking for opportunities to counterattack Cao Shuang. In this way, Sima Yi lay on the sickbed for two years. When the little emperor led his courtiers out to worship their ancestors, Sima Yi took this opportunity to launch a coup d'état. In the end, he successfully seized power and eliminated Cao Shuang and some previous opponents of him, and completely became a figure who wei guo said. At this time, it had been 15 years since Zhuge Liang's death. It was precisely because of the internal strife in the State of Wei that Sima Yi had no time to take care of others, which led to the fact that after Zhuge Liang's death, the State of Shu also experienced more than ten years of peace. Therefore, after Zhuge Liang's death, the Shu state was obviously not so powerful, this was a good time, he did not want to attack the Shu state, but he himself was difficult to protect!
