When Mi Yang was in later generations, he carefully understood the reasons for Ji Han's demise.

It is true that there are many reasons for the demise of Ji Han, but they are mainly divided into three aspects.

Politics and economics are not to mention, but the military aspect is not just "smuggling" can be summed up in four words.

First of all, Deng Ai is a military master, since he dares to smuggle Yinping, it must be because Yinping has the possibility of being smuggled, and after successfully smuggling Yinping, it will tear a huge hole in Ji Han's defense line.

Without these two judgments, Deng Ai would not have been so risky.

But Deng Ai knows these two things, can Fa Zheng and Zhuge Liang not know?

These two masters knew, and after Liu Bei took Hanzhong, they took precautions against these two points.

The Hanzhong defense line laid out by the two great talents is like a tight defense network, guarding the gateway that is vital to Yizhou.

In this tight defense network, Yinping and Yang'an Pass are two extremely important hubs.

Yang'an Pass is Yangping Pass, also known as Guantou.

Anyone who knows anything about the history of the Three Kingdoms should have heard the names of these two fortresses, especially Yangping Pass, which is almost the life of Hanzhong.

Because once Yangping Pass is taken by the enemy, it means that the biggest natural danger in Hanzhong has been lost.

When Cao Cao and Liu Bei attacked Hanzhong, they both regarded Yangping Pass as the main direction of attack at the beginning.

When Fa Zheng was alive, he once said: "The recovery of the fish is really the door of good and bad for Yizhou." ”

From this point, it is enough to reflect that Yangpingguan is an extremely important throat for the entire Yizhou.

The Hanzhong defense network jointly arranged by Fa Zheng and Zhuge Liang not only had heavy troops in Yinping and Yangping.

They also left heavy troops in various passes not far from these two passes, and many passes were staggered and echoed each other, so that Hanzhong was properly guarded.

But it's a pity that the defense net that guarded Ji Han's safety in history was destroyed by one person.

That person was Jiang Wei, who inherited Zhuge Liang's legacy and was the general of Ji Han at the time.

The reason why Jiang Wei wanted to destroy the defense network built by Zhuge Liang with his own hands was not that he had bad intentions, on the contrary, his original intentions could be said to be good.

Jiang Wei also admitted that Hanzhong's tight defensive network could defend against the enemy well, but he believed that the tight defensive network would not allow him to achieve great results.

Therefore, Jiang Wei suggested that Liu Chan might as well use the abandonment of some important fortresses as bait to lure the enemy army to take the initiative to attack.

Then his army retreated to the two cities of Han and Le, and the remaining important passes were guarded by heavy troops.

He sent another army as a mobile force, waiting for an opportunity to attack the enemy's weak points.

If this goes on for a long time, the enemy army will be exhausted, and when the enemy army retreats, the defenders of Zhucheng and the mobile troops outside will take the opportunity to attack together, and they will be able to annihilate all the enemy troops.

When Jiang Wei's suggestion was sent to Liu Chan before and after, Liu Chan readily agreed to Jiang Wei's suggestion.

On the surface, Jiang Wei's strategy of "collecting troops and defending the wilderness" is very beautiful, but he ignores a key issue:

That is, the original defense network in Hanzhong paid attention to the interlacing of dogs and teeth, echoing each other, but in the case of the Han army taking the initiative to abandon part of the fortress, the biggest advantage of this defense network was destroyed.

The most fatal thing is that the heavy troops originally stationed at Yinping and Yangping Pass were withdrawn, which gave the Wei army a chance.

In history, after Jiang Wei got the news that Zhong Hui was in charge of the military pass, he immediately sent a letter to Liu Chan, asking Liu Chan to send Zhang Yi and Liao Hua to garrison Yangping Pass and Yinping Bridgehead respectively to prevent trouble.

From this point, it can be known that the troops of Yinping and Yangping Pass must have been very weak at that time, otherwise Jiang Wei would not be in such a hurry.

Maybe Jiang Wei's negligence at the beginning was just a trigger, after all, he also thought about saving it later.

But when his negligence happened to meet Liu Chan's mediocrity, it would become a great disaster.

One of the reasons for the loss of Yangping Pass in history was Jiang Shu's surrender to the enemy, which allowed the Wei army to take advantage of the situation to attack the city.

But Jiang Shu was only a deputy general, and it was only his headquarters soldiers and horses that he took out of the city to surrender.

After he took his headquarters soldiers and horses out of Yangping Pass, he led to a dangerous pass like Yangping Pass that could be directly attacked and captured by the Wei army.

It can be seen that under Jiang Wei's strategy, how empty the troops of Yangping Pass are.

Jiang Wei's strategy is very much in line with his military style, and he is bold and good at taking risks.

His heart is also good for the big man, and he wants to kill more enemies for the big man, but unfortunately, from the objective facts, Jiang Wei's strategy is indeed to give the enemy a chance.

Even with the lesson of Cao Shuang's great defeat, if Jiang Wei did not take the initiative to destroy Hanzhong's defense network, it is not certain whether Sima Zhao would rashly order the destruction of Shu.

After all, Sima Zhao's father, Sima Yi, was able to get the support of many old ministers, and a large part of the reason was that Cao Shuangxing's defeat was too miserable, which directly and seriously hit his prestige.

Moreover, Sima Yi was the most fearful of the tight defense network in Hanzhong, which was also the biggest reason why he opposed Cao Shuang's southern expedition.

On the one hand, it is the Hanzhong defense network that his father is afraid of, and on the other hand, the tragic end of a powerful minister like himself, Sima Zhao will carefully weigh it no matter what.

For Jiang Wei, a tragic hero, Mi Yang from later generations is also very fond of him.

It is precisely because of his love that whenever he reads this record in the history books, Mi Yang often feels extremely sighing.

Maybe if Zhuge Liang has a spirit in the sky, he will also be in a state of mind after seeing Jiang Wei, who he has high hopes for, adopt this strategy.

That's why Zhuge Liang wrote to Mi Yang and took the initiative to remind him of this.

After all, Mi Yang's past style of using troops is also good at luring the enemy into depth.

In other places, it is a good strategy to lure the enemy deep at other times, but in Hanzhong, under the current situation, Zhuge Liang does not want Mi Yang to do this.

Because Hanzhong is the gateway to Yizhou, today's situation is a turbulent time for the Han Dynasty.

If Mi Yang is negligent and the enemy army takes advantage of it, then the chain reaction will be fatal to the Han.

Looking at Zhuge Liang's earnest teaching in the letter, Mi Yang felt warm, and at the same time, he also deeply remembered Zhuge Liang's instructions in his heart.

Mi Yang is not a horse, he likes to disobey Zhuge Liang's reminder to show his ability.

Moreover, even if there is no reminder from Zhuge Liang, Mi Yang, who knows the lessons of history, will not think of taking risks in guarding against Hanzhong.

After reading Zhuge Liang's letter, Mi Yang took Zhuge Liang's letter into his arms.

In the letter, Zhuge Liang not only reminded Mi Yang, but also agreed to Mi Yang's move to divide his troops south.

As long as there are not too many soldiers and horses, the impact on the defense of Hanzhong is not great, and the current Yizhou does need reinforcements.

Thinking of this, Mi Yang quickly came up with a number in his heart - five thousand.

Five thousand may not sound like much, but the five thousand Liang troops that Mi Yang was going to send to the south were all well-trained regular soldiers.

It is too exaggerated to say that such an army is one enemy with one hundred, but in the face of the barbarians in Nanzhong who are not well-armed and have incomplete armor and stomach, it is still no problem to fight a few in a head-to-head duel.

Moreover, even if there is turmoil in Nanzhong, with the economic foundation of Nanzhong, the rebels will not exceed 20,000 at most.

Under such circumstances, the five thousand Liangzhou reinforcements were not small.

After deciding on the number of troops to send south, Mi Yang immediately asked Fa Miao to write a military order.

In this military order, Mi Yang appointed Deng Ai as the chief general of the 5,000 southbound Liang army.

In addition, he also sent Fu Bai, Shi Bao and other new generals who had recently joined his army and had not yet made military exploits to this army.

Zhuge Liang's expedition to Nanzhong, unless Meng Shu and others can summon meteorites, Mi Yang knows that this battle is for Zhuge Liang to practice.

In that case, why don't you hurry up and send those people to Zhuge Liang's side to brush up on their military exploits?

If Zhuge Liang takes a fancy to some of his generals and mentions a few words, it will be even more profitable.

Then Mi Yang issued another military order.

"Order Zhang Wei to lead 3,000 troops to garrison Yinping."

At Yangping Pass, Mi Yang had originally sent Wu Yi to garrison it, and under Zhuge Liang's reminder, Mi Yang was ready to continue to strengthen Yinping's defenses.

Yinping is a pass that is in danger of not losing Yangpingguan, and Zhang Wei himself is quite stable, so it is very appropriate to send him to guard Yinping.

Although Fa Miao didn't know why Mi Yang strengthened Yin Ping's defenses, he still quickly wrote these two military orders.

After Fa Miao wrote the two military orders for Mi Yang to see, Mi Yang immediately ordered someone to send these two military orders to Nanzheng.

Seeing the messenger quickly run out of the big tent with the military order, Mi Yang continued to deal with the government affairs in his hand.

At the same time, an idea crossed his mind.

Although the current Hanzhong is not suitable for a big war, if an enemy dares to hit the door, then he is not easy to provoke.

Don't forget, he's a general who started by fighting back on defense.

I don't know how Sun Shiwan is doing recently.

...

When Mi Yang continued to further strengthen the defense of Hanzhong, Cao Zhen, who had been working day and night, finally arrived in Luoyang.

Cao Zhen's return to Luoyang this time was on his own initiative and did not inform anyone in advance, so his return was sudden.

When Cao Zhen returned to the mansion, Cao Shuang was enjoying the beauty of Wushisan with his friends Deng Yang, Li Sheng, He Yan and others.

】

After being drunk, the five stones can make people feel like they are fluttering.

In addition, under the leadership of He Yan, Wushisan soon became popular among the nobles in Luoyang City.

Ordinary people will have a hot and restless reaction in their bodies after taking Wushisan, so Wushisan is also considered by some people to be an aphrodisiac.

Of course, no matter how bad Cao Shuang is, he will not do anything like prostitution in public during the day.

It's just that after the effect of the medicine comes up, they all untie the clothes on their bodies to dissipate the heat in their bodies.

However, although this kind of behavior is not as dirty as prostitution in public during the day, it is also intolerable to the world in terms of the etiquette of the time.

So when Cao Zhen came home and saw his son behaving like this, the anger in his heart suddenly rose with his upright temperament.

Cao Zhen walked quickly to Cao Shuang's side, and lifted Cao Shuang, who was still showing enjoyment on his face, from the couch.

Cao Shuang, who was still fluttering like a fairy, was not very clear at this time, and in a trance, he couldn't see clearly that the person in front of him who dared to disrespect him was his father.

So subconsciously, Cao Shuang let out a loud shout in his mouth: "Presumptuous! ”

Hearing that Cao Shuang dared to drink at himself, Cao Shuang's anger in his heart was even worse, and he directly slapped Cao Shuang to the ground.

Cao Zhen is famous for his courage in Cao Wei, when he was young, he was able to shoot tigers, and his slap under anger was not something that ordinary people could bear.

When the heavy slap fell on Cao Shuang's face, it not only made him fall directly to the ground, but also made him scream in pain.

At this moment, Cao Shuang felt that his face was about to explode in pain.

But it was this intense pain that made Cao Shuang completely sober up from his delirium.

When he saw that it was Cao Zhen who beat him, the anger in Cao Shuang's heart disappeared suddenly.

For this stern father, he was afraid from the bottom of his heart.

Ignoring the pain on his face, Cao Shuang was so frightened that he got up from the ground and knelt in front of Cao Zhen, his body shaking constantly.

It's scary.

And when Cao Zhen saw Cao Shuang's uncompetitive appearance, he had the urge to draw a knife.

Cao Shuang is his eldest son, so Cao Zhen has always had high hopes for Cao Shuang.

The depth of love is the responsibility of responsibility.

thinks that when he was young, he was also a handsome man who was praised, how could he have such an uncompetitive son.

And this kind of change in the field also scared Cao Shuang's fox friends to wake up.

The majesty of the great general is something that ordinary disciples of the family can resist.

Even He Yan, who was the same generation as Cao Zhen, slowly sat up straight after seeing Cao Zhen's return, because he was afraid of Cao Zhen's might.

It's just that although he is angry in his heart, Cao Zhen didn't come back this time to educate his son, he still has more important things.

So after Cao Zhen warned Cao Shuang not to take Wushisan in the future, he went back to his bedroom to bathe and change clothes.

Cao Zhen, who fought on the battlefield, naturally retained an aversion to Wushisan, a drug that would invade people's sanity.

After bathing and changing clothes, and washing all the fatigue from the outside, Cao Zhen put on his court clothes and sat on the chariot, and walked quickly towards the palace.

When Cao Zhen arrived at the palace gate, after revealing his identity, he walked all the way to Cao Pi's dormitory unimpeded.

As the hottest minister of Cao Wei today, Cao Zhen has a lot of privileges in Luoyang.

Soon after, Cao Zhen came to the outside of Cao Pi's dormitory.

When standing outside the dormitory, no matter how powerful Cao Zhen was, he still honestly let the yellow door outside the hall enter to tell him.

Cao Wei is not Ji Han, no matter how powerful Cao Zhen is, no matter how friendly his personal relationship with Cao Pi is, there must be a clear boundary between the monarch and the minister.

Huang Men saw that it was the general who asked to see him, and he immediately ran into the main hall to report.

It's just that it was not Cao Pi who accepted the report from the Yellow Gate, but Guo Guifei, who recently favored the harem.

Unlike later generations, the current noble concubine was already a title in the harem second only to the queen.

At present, Cao Pi has not established a queen, and it can be said that Queen Guo is the de facto queen of today's Great Wei.

After Guo Guifei heard that it was Cao Zhen who asked to see her, a look of surprise immediately appeared on her face.

Cao Zhen, as the governor of Cao Wei Guanzhong, suddenly returned without an edict, there must be something important to do.

It's just that.

Guo Guifei glanced at the inner hall, and when she thought that Cao Pi was now taking Wushi San, a look of hesitation appeared on her face.
