After Zhuge Liang died of illness, why did Sima Yi not attack Shu for the rest of his life?

After Zhuge Liang died of illness, Sima Yi never attacked Shu again. That's because Sima Yi thinks that Zhuge Liang is dead, and Shu Han has only one Jiang Wei left to be afraid of, so it is better to wait and see how they themselves decay.

First, the relationship between Zhuge Liang and Sima Yi.

In the Romance of the Three Kingdoms, whether it is Zhuge Liang or Sima Yi and others, they are the leaders of the Three Kingdoms period, which has left a deep impression on people, we know that in that period of the Three Kingdoms, Sima Yi's Cao Wei regime can be said to be the most powerful party in the Three Kingdoms, and Zhuge Liang's Shu Han is the weakest party in the Three Kingdoms, but despite this, throughout the history of the Three Kingdoms, the Shu Han regime is the most combative country, and Sima Yi and Zhuge Liang are also a pair of enemies and have a deep origin.

Second, Zhuge Liang died.

Since Liu Bei died, Zhuge Liang supported the young master, inherited Liu Bei's will, several Northern Expeditions, but unfortunately there were no results in the end, Sima Yi knew Zhuge Liang's ability, plus he also suffered a lot of losses in the hands of Zhuge Liang, so he adopted the tactics of delay, passively avoided the war, and finally succeeded in dragging Zhuge Liang to death, in Zhuge Liang's last Northern Expedition, died of illness in Wuzhang Plain, without Zhuge Liang's henchman, there is no one who can be equal to Sima Yi's ability in Shu Han, But later Sima Yi did not take the opportunity to destroy Shu Han.

Third, because Sima Yi knew that Shu Han would not go far.

Many people think that Sima Yi is not Zhuge Liang's opponent, but Zhuge Liang is dead, Sima Yi has not targeted Shu until how many years later, Sima Yi's son Sima Zhao said a word, which let people know the reason, it turns out that in Sima Yi's eyes, Zhuge Liang is dead, and Shu Han has no one who poses a threat to him, but he still did not attack Shu Han, because he thinks that Shu Han without Zhuge Liang is not afraid at all, rather than Xingshi moving people to go on an expedition, it is better to wait and see what happens, Sure enough, later Shu Han declined more and more for various reasons, and finally went to extinction.

After Zhuge Liang died of illness, Shu was in danger, why didn't Sima Yi attack for the rest of his life? He's not stupid.

Although Zhuge Liang died of illness, Sima Yi knew that Shu was not in chaos, and Sima Yi was also facing Cao Shuang's seizure of power at this time, and Sima Yi died of illness shortly after defeating Cao Shuang.

Because Sima Yi didn't have any extra time at that time. After Sima Yi defeated the Cao family, he also had to face other families within the Wei State at that time, so he didn't have so much time to attack the Shu State.

Because there is no need for him to put his mind on this, and the Shu Kingdom without Zhuge Liang has no threat to Cao Wei.
