Why didn t Sima Yi attack Shu in his life after Zhuge Liang s death?

Because Sima Yi knew that the Shu State at that time had no way to resist him, and he was also afraid that after he eliminated the Shu Kingdom, he would be deposed by the emperor.

Because Sima Yi has been forbearing, he doesn't want to waste his strength.

Because he was busy building his strength, Cao Wei would use a knife against him at any time as soon as Zhuge Liang died.

Sima Yi's ambition was not to destroy Shu, but to overthrow and replace the Cao regime. The state of Shu was strong for a while because of Zhuge Liang's existence, and because of Liu Bei's death, Zhuge Liang decided to go on a northern expedition, and Sima Yi was also reused by the Cao clan and had the opportunity to realize his ambitions. Zhuge Liang's death would instead weaken the strength of Shu and make Cao Wei more prosperous, which was not conducive to Sima Yi's ambitions, so he instead stopped his campaign to exterminate Shu.

Because the Shu Kingdom was more united after Zhuge Liang's death, and Zhuge Liang had repaired the relationship between Shu and Eastern Wu before his death, Sima Yi did not dare to attack rashly.

Because Sima Yi was busy quelling the rebellion in Liaodong and had been dealing with the matter of Tuogu, when the Wei State stabilized, he was already in his 70s, so he was unable to attack.

After Zhuge Liang's death, the reason why Sima Yi did not attack Shu Han was because there were bigger enemies within Cao Wei, and the geographical location of Shu Han was easy to defend and difficult to attack, and it was difficult to break through, plus the previous battlefield had been in Cao Wei's territory, Cao Wei also needed to recuperate, and even the emperor Cao Rong at that time had no intention of attacking Shu Han, and if Sima Yi insisted on attacking Shu Han, it would also cause the emperor's suspicion.

Sima Yi is a person who is very knowledgeable about current affairs, he knows that after Zhuge Liang died, he has no enemies, since ancient times, the birds have been hiding with good bows, if he can not retreat in time, there will definitely be a disaster of killing, so the top priority is to hand over the military power first, so that the emperor can rest assured, it turns out that Sima Yi's hand is extremely wise, although Cao Rong politely refused, but in the end he was very happy to accept Sima Yi's request, and gave Sima Yi a civil position in the court, since then Sima Yi has behaved honestly, Cao Rong gradually relaxed and no longer doubted Sima Yi.

Sima Yi knows his confidant, although Zhuge Liang is dead, but the heritage of Shu Han has not suffered any loss, but because the battlefield has been in Cao Wei's territory, the people are in urgent need of recuperation, in this case it is not appropriate to move troops, and since ancient times, it is difficult for Shu to go to the blue sky, they are not familiar with the terrain of Shu Han, and the probability of failure to attack rashly is greater, and at that time he will be the general of the defeated army, and he is likely to be punished by the emperor, and now he has successfully consumed Zhuge Liang, and the honor has reached its peak. It's better to accept it when you see it, and you can still get a good reputation.

In fact, Cao Ei has been very tired over the years, because of the existence of Zhuge Liang, once ran around, Sima Yi knew the emperor's thoughts, but he would never say it directly, but pretended that he was overwhelmed by the heavy responsibility, it was difficult to lead troops to fight, which happened to cater to Cao Ei's mind, and then Cao Ei completely relaxed, behaving like a faint gentleman, and within a few years, he died because of his addiction to small music, although this was not in Sima Yi's plan, but it also showed that Cao Ei really did not want to attack Shu Han.

After Zhuge Liang's death, Sima Yi did not attack Shu, on the contrary, Sima Yi was in a hurry to take advantage of the chaos to attack Shu, but Cao Yi did not agree. Later, Sima Yi was busy quelling the rebellion against Gongsun Yuan of Liaodong, busy fighting for power with Cao Shuang, busy with a coup d'état, busy with quelling the rebellion, and finally never had a chance to kill Shu until Sima Yi's death.

Sima Yi knew that Zhuge Liang had left a way for Liu Shan to retreat, he felt that Zhuge Liang's scheming was unfathomable, and he didn't know what the consequences would be if he attacked rashly.

Because Sima Yi originally wanted to share a point with Zhuge Liang, because he admired Zhuge Liang more, but after Zhuge Liang died, he felt that there was no need to attack.

I think there are two reasons, one must be that Emperor Wei Ming is afraid that Sima Yi will have something to do on the way to attack Shu, after all, the mountains are high and the rivers are far away, so he has been stopping him from attacking. Another reason should be that there is no stability within the country, and the road to Shu is not easy to walk, so you can't go immediately.

Emperor Wei Ming was quite afraid of Sima Yi. Therefore, it is impossible to let Sima Yi hold the military power to attack Shu. Perhaps Emperor Wei Ming thought that Sima Yi would definitely rebel or rebel on the way to attack.

In short, Emperor Wei Ming should have wanted to firmly control Sima Yi by his side, so that he had no other thoughts.

Secondly, Sima Yi himself should have considered Emperor Wei Ming's thoughts, so he would not act rashly.

Let's talk about Shu, Shu is now the Sichuan Basin, the mountains are high and the rivers are far away, and the road is not easy to walk. It can be said that the geographical location of Shu is easy to defend and difficult to attack. When Cao Wei was not completely stable internally, there was no need to waste a lot of manpower and material resources to attack Shu.

After all, if you want to go outside, you must be inside.

If Sima Yi had to send troops, then Cao Wei's forces might take advantage of the problem, and Sima Yi didn't need to take this risk if he didn't fight steadily.

In fact, to put it bluntly, if the relationship between Sima Yi and Emperor Wei Ming is like that between Liu Bei and Zhuge Liang, then Shu will definitely be in danger. However, it is a pity that Emperor Wei Ming did not trust Sima Yi, and Sima Yi could not assist Emperor Wei Ming completely unguarded.

So in such an awkward relationship of mutual restraint, Shu was very stable. Before, there was no way to fight Shu, but later Sima Yi's family was called the emperor, and there were more important things, so Shu was ignored again.

I think that because after Zhuge Liang's death, Shu did not pose a great threat to Sima Yi, so he did not attack again in his life.

I think Sima Yi is here. After Zhuge Liang died, he never attacked Shu again in his life, because Sima Yi's focus was on rebellion at that time.

After Zhuge Liang's death, I no longer had a strategist comparable to Sima Yi. In Sima Yi's view, Shu is no longer a stumbling block.

Because Sima Yi felt that after Zhuge Liang died, Shu was useless, and he didn't have to go to great lengths to fight Shu.

After Zhuge Liang's death, Shu no longer had a strategist who could match Sima Yi, and after Zhuge Liang's Northern Expedition, Shu's military and civilian strength were also somewhat weakened, and it no longer posed a threat to Sima Yi.

Zhuge Liang and Sima Yi can be said to be both opponents and heroes! After Zhuge Liang's death, Sima Yi had no good opponents to play, originally they were opponents and involved each other, without Zhuge Liang, Sima Yi became dispensable. Sima Yi retired several times and came back to ......Because he knows that only the war in the Wei State will reuse him!

Only then can he safely and secretly cultivate his army. If you attack Shu, the mountains are high and the roads are far away, and you will lose your troops! Once he captures Shu, it must be Sima Yi who guards Shu, and the barren and peaceful land of Shu is not what he wants, what he wants is the powerful Wei State!

After Zhuge Liang's death, Shu Han was no longer a threat. After Zhuge Liang's death, Sima Yi lost his strongest opponent, and he really felt how sad it was to be invincible!

After Zhuge Liang's death, Shu didn't have much strength, so Sima Yi didn't need to spend a lot of energy at all.

Because he could have shot Sima Yi to death in Wuzhangyuan with a volley of arrows, and Zhuge Liang forgave him according to God's will, maybe out of gratitude.

Because Sima Yi understood that if Shu was defeated, then the Cao Wei group would soon open a knife on him.

If you fight again, you will destroy Shu. The Wei family will then destroy the Sima family.

When did Sima Yi attack Shu?

In my opinion, after Zhuge Liang's death, Sima Yi thought that there was no need to expend troops to attack Shu. There won't be any more big moves.
