After Zhuge Liang died of illness, why did Sima Yi stop attacking Shu for the rest of his life?

Because after Zhuge Liang died of illness, Sima Yi also faced the contradictions between Cao Wei and the Sima family and the internal strife between the Sima family, and had no time to attack Shu.

1, between Cao WeiStruggle of internal forcesSo that he has no energy to attack other countries.

2. Without the approval of the monarch.

3. Years of war also require the restoration of national strength.

Death of Emperor Wei Ming

After Zhuge Liang's death, although Sima Yi had one less strong opponent, he was still mired in internal and external troubles, so he was not free for a while.

When Zhuge Liang had just died, Sima Yi wanted to attack Shu, but he did not get the emperor's approval, and then Cao Wei's internal strife left him with no energy to attack Shu.

After Zhuge Liang's death,Sima Yi was busy with the infighting of the Sima family, busy fighting for power, naturally he will not spend energy attacking the precipitous Shu land, because fighting will consume his strength, and it is very risky.

Because after Zhuge Liang's death, the main contradiction in Wei was the power struggle between the Sima clan and the Cao clan, so Sima Yi had no time to take care of the Shu state.

This has little to do with Zhuge Liang's death, mainly because Sima Yi was short of money at the time, and there were many struggles in the family, and he didn't have time to attack Shu.

It is not that Sima Yi did not besiege Shu, but because Sima Yi missed the best time to attack and made Shu prepared, so Sima Yi did not risk his life and did not have a head-on confrontation with Shu, not because of Zhuge Liang's death.

The war is not based on a whim, it depends on the right time, place and people, and all opportunities are sufficient to attack, comparing Zhuge Liang and Sima Yi, Zhuge Liang did not get the opportunity to really attack Wei, and the result of the strong attack was actually six out of Qishan basically did not gain an inch of land; And Sima Yi can see that the qi of Xishu is not exhausted, and the conditions for attacking Shu have not been met, so he waits for work, and waits for it, sure enough, Jiang Wei's Nine Expeditions to the Central Plains are the same as Zhuge Liang, too careful, exhausting the qi of Xishu, waiting for the opportunity, Sima Zhao broke Shu Han in one fell swoop;

Because Zhuge Liang is Sima Yi's powerful opponent, and Sima Yi respects Zhuge Liang more, he will not attack Shu for the rest of his life.

Because the Shu Kingdom had developed very well at that time, and Sima Yi was not skilled at all, he needed to deal with Gongsun Yuan.

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.

Because Sima Yi still has a lot of thoughts, he is very good at foresight, and he will make a lot of preparations before attacking Shu.

Because Sima Yi was afraid that Zhuge Liang was pretending to die of illness. And he also hoped that Dongwu would consume the strength of the Shu army. So he didn't strike right away.

Because he thought that the Shu Kingdom without Zhuge Liang would not pose any threat to Cao Wei, it was necessary for him to prepare to avoid being unloaded and killed by the donkey.

After Zhuge Liang's death, Wei would no longer let Sima Yi take charge of the troops, and he had no chance to lead the troops at all.

Because Sima Yi and Zhuge Liang had already made an agreement when they were alive.

Because Sima Yi was already exhausted from the confrontation with Zhuge Liang, and the only opponent who put him under pressure, Zhuge Liang, had also died, he felt that he had no energy to manage military affairs anymore.

Because after Zhuge Liang's death, Sima Yi was busy stabilizing the situation of Cao Wei, and it was the Sima family that was completely in power, and Sima Yi died after stabilization, so there was no crusade against Shu.

Because he has to find a way to protect himself, without Zhuge Liang, he will have no value in Cao Wei, and he may be killed at any time.
