With the replenishment of new recruits, the Wei army was not only superior in numbers and reserves.

In terms of quality, it is also getting closer and closer to the Shu army personally trained by Zhuge Liang.

However, the main enemy faced by the Northern Expedition was not Sima Yi.

In Zhuge Liang's series of Northern Expeditions, for a long time, he was fighting with Cao Zhen.

In the Battle of Jieting, in order to highlight Sima Yi in the romance, the role of Cao Zhen and Zhang He was downplayed.

However, in fact, Sima Yi did not participate in this war.

In the whole process of Wei Shu's confrontation, the duel between Cao Zhen and Zhuge Liang is the main content.

A few back-and-forth in a row can be regarded as a mutual victory or defeat.

It was not until Cao Zhen's death that Sima Yi became the commander of Wei in the west.

However, Sima Yi, who had just ascended to the throne, did not attach importance to the country, and killed Zhang He by the hand of Zhuge Liang.

And with Zhang He's death, he warned other Wei generals that they should wait for work and stick to it.

Naturally, although this insistence seems to be levelless, it has successfully dragged Zhuge Liang to death.

Obviously, Sima Yi will not be smarter than Zhuge Liang, but it is indeed the last straw that crushed Zhuge Liang.

After all, Zhuge Liang has too many things to do, and he has indeed killed many people with different personalities before and after.

However, people do not have unlimited energy, and exhaustion does not necessarily lead to the desired results.

Therefore, from the perspective of Wei Shu's series of wars, Sima Yi became the ultimate beneficiary.

After all, all the generals of the Cao clan and the Xiahou clan who could fight well were fighting against Zhuge Liang, and Lu Xun's series of confrontations were wiped out.

The remaining veteran general Zhang He, who had outstanding military achievements, was also killed by Sima Yi and Zhuge Liang.

As the veterans gradually withered away, the generals were outside, and the entire Wei State gradually underwent changes.

A generation of new people replaced the old, and when this series of events happened, the Sima brothers, who implemented the new policy in Luoyang, became the leaders of the scholar clan.

Due to the proud achievements of the New Deal, Zhong Hui, Deng Ai and other young talents of the Wei State became Sima Yi's protégés.

Among the old qualifications, only Yang Fu and Chen Qun are still active in the imperial court, constantly making suggestions.

That's why Cao Rong became more and more worried as time went on.

Because, although the country is getting richer and stronger, there are no outstanding talents in the royal family, and even the important ministers of Cao Cao and Cao Pi's era have withered one by one.

Xiahou Xuan, who is the only one who has a little talent in the future, is not so appetizing.

As a proud monarch, Cao Rong naturally would not force his experience to reuse Xiahou Xuan.

So, after looking left and right, Cao Rong found that there was no one else around him who could share the pressure, and only one Sima Yi was left.

Naturally, the more this is the case, the more uneasy it makes Cao Rong feel uneasy.

After all, Zhang He's death may not be clear to others, but Cao Rong can see it clearly.

However, at this time, Sima Yi's sin could not be cured.

After all, Zhonghui, Deng Ai and others are still young, and the normal operation of the imperial court and the continued implementation of Tuntian are inseparable from the strong execution of Sima Yi and Sima Fu's brothers.

In this process, the successive early deaths of his three sons made Cao Rong feel even more painful.

So, in the days that followed, it was natural to start building a new palace.

After all, in ancient times, this kind of continuous early death was indeed a very painful thing.

As the so-called unfilial piety has three, no queen is greater.

So in order to change this situation, Cao Rong, who had been childless for a long time, began to look for feng shui treasures to build a large number of buildings.

Although Yang Fu still often admonished, Cao Rong no longer listened.

As a result, Yang Fu was depressed and resigned and died of illness, and at the same time, the pressure of more than ten years of reform and the blow of not having children gradually dragged down Cao Rong's body.

Because, in the reform, these clans that can't support the wall have become the biggest opposition force, and in the face of these clans that oppose the reform, Sima Yi can't and doesn't dare to operate directly, so Cao Yi can only resist the pressure by himself.

However, the whole process is tough.

After all, with the prevalence of hedonism, it seems that very few people in the clan have been able to share their worries.

Naturally, for the descendants of the Cao family and the Xiahou clan who have not experienced hardships, Cao Rong is also as exhausted as Zhuge Liang.

However, after Cao Zhen's death, there was no one who could share his worries in the end.

So, in the repeated thinking of "the tallest among the short", Cao Rong finally had to choose to let Cao Zhen's son come to the platform.

After all, the long-term pressure of reform and the two-front battle against Shu and Wu had brought Cao Ei's body close to the limit.

If you don't make a choice, time will make it automatically.

And the choices that time makes automatically are often more painful than the active choices.

And Cao Zhen has always been Cao Ei's most trusted person, so after thinking about it again, Cao Shuang became the best choice.

As a result, Cao Shuang can be regarded as standing on the top stage of the Wei State.

It is known that it was this operation that led to the end of the Wei era.

However, Cao Rong really has no better choice, although Xiahou Xuan is a talent from the current historical evaluation.

However, in Cao Rong's eyes, he was no different from other mediocre Cao clans, and Cao Zhi had already taken a step ahead.

Looking at the gradually withering clan, Cao Rong closed his eyes unwillingly.

After all, as a reformer in this life, Cao Rong made Wei's comprehensive national strength have been greatly improved.

However, the high-intensity work seriously overdrafted everything for Cao Ei.

Finally, when it was time to reach the end, I looked around, but in the end I couldn't find a really suitable successor.

Although Sima Yi on the side was the sharpest sword in his hand, he had no other sword in his hand to use. There had been other swords before, but they had all been rusted and broken.

Naturally, Cao Rong understood that once he closed his eyes like this, such an incomparably sharp sword would probably no longer be controlled by others.

In this way, even if Cao Shuang was appointed as the minister of care, Cao Rong felt very unsafe. After all, Cao Shuang's long-term performance can score a maximum of 50 points. However, at this time, there was no better way, so he could only become a dead horse doctor.

Cao Rong regretted why he didn't pay attention to his body before, but it was freezing three feet, not a day's cold, and there was no other way at this time.

Therefore, even if Cao Rong is very unwilling, there is no way.

Although he had the intention of destroying Sima Yi's sword, which might get out of control, however, as time passed, Cao Rong found that he could not destroy this sword.

Because, this is the only sword left in Great Wei, and even Cao Ei himself does not dare to leave such a sharp sword.

Cao Rong didn't dare to imagine what the entire Wei Kingdom would have been like if there was no such a sharp sword.

Naturally, the rest is clear to everyone.

After Cao Rong's death, the monarch of Wei was almost the same as Emperor Xian of Han.

Because of the support of the clan, Cao Shuang's forces looked very strong, and even Sima Yi chose to avoid the edge for the time being and pretended to be sick.

So, Cao Shuang, who got carried away, stood in the center of the stage and started various funny performances, and after a long time, he even had the idea of replacing the throne.

After all, with Sima Yi's recuperation, no one in the court dared to speak loudly in front of Cao Shuang.

Life was too good, Cao Shuang finally completely forgot Cao Ei's explanation, and did not cultivate Cao Ei's successor Cao Fang well.

Naturally, Cao Shuang, who finally expanded, also ushered in the price of underestimating the enemy.

Sima Yi fought back and closed the gates of Luoyang.

In fact, this is also a dangerous move for Sima Yi.

After all, there is no military power in his hands, and controlling Luoyang is already the limit of Sima Yi at this time.

Although the real power figure Deng Ai and others are Sima Yi's protégés, the nature of such a thing as controlling Luoyang is actually very bad.

Most people are unlikely to support Sima Yi's move.

Even if it has reached the worst situation, if Cao Shuang issues the order of King Qin, the entire Luoyang will still be surrounded by several layers, and Sima Yi will die without a place to be buried.

However, the long-term "invincible" rich life completely destroyed Cao Shuang's survival instinct.

Cao Shuang didn't know that military power was his last guarantee.

Under Sima Yi's promise, Cao Shuang easily gave up the last chance.
