Actually, there is one point, Qin Lang miscalculated.

In fact, Zhang Xi knew the actual deployment of troops in Yecheng now.

An unknown senior worker surnamed "Liu" has been in contact with Zhuge Liang during this time, and the secret letter between Zhang Xi and Zhuge Liang has never been broken.

Therefore, not only Zhang Xi knew that Yecheng was empty now, but Zhuge Liang also knew about this situation.

These two people, in fact, have thought about whether to use partial divisions to contain the defenders of Wenxian County, let Zhang Xi lead the Qianghu cavalry to open the way, and 20,000 infantry as backups, drive straight into the possibility of sneaking into Yecheng.

But after thinking about it, the two of them finally gave up this practice.

The reason is also very simple, it is too risky to use soldiers in this way.

In history, Deng Ai was able to smuggle through Yinping successfully and destroy the country in World War I, in addition to Deng Ai's own ability, the most important factor was his opponent, Liu Chan.

But Cao Rong is not Liu Chan, and even speaking, the two of them are not monarchs of the same level.

Cao Rong is a brave and effective Ming Jun, at least compared with Liu Chan, he is indeed much wiser.

Yes, Cao Rong in history, after Zhuge Liang's death, thought that the Shu thief was no longer a threat, and he was indeed somewhat indulgent because of this, but at most he continued to play music and dance, and this indulgence was nothing at all with the foundation of Da Wei.

But Liu Chan is different, not only does he continue to play music and dance, he can't even control the thoughts of his subordinates.

You must know that at this time, Ji Han had only one state, and the foundation of the country was still two Han heirs.

Inaction, failure to go on a northern expedition, is the original sin.

Prime Minister Zhuge Cheng, who can operate to the limit and desperately pull the national strength, is no longer there, and Jiang Wan, Fei Yi, Dong Yun, Chen Yi and others who can barely maintain the situation have passed away one after another. At this time, you are still standing up, and you are still playing music and dancing, isn't that looking for death?

Liu Chan is indeed not a faint monarch, but he is a mediocre monarch, and in troubled times, a mediocre monarch is a sin.

Of course, saying so much is not to belittle Liu Chan, Zhang Xi's idea is actually very simple - even if he leads his troops north and attacks Yecheng, Zhang Xi does not think that a monarch like Cao Rong will rush to the hospital and hand over his last hope to a man who has never been on the battlefield, and after being approached by enemy soldiers in the city, he will choose to give up holding on and surrender in Kaecheng.

Not to mention anything else, Man Pet is still in Yecheng now, if this old guy really wants to play with his life, it is not easy to mess with.

This is Zhang Xi's concern, and Zhuge Liang, of course, he will not know what "smuggling Yinping" is, but it does not prevent him from thinking that this kind of operation is not feasible through rational analysis.

Cao Rong is also a Ming Jun in the end, and he can be regarded as a good person, such a person is sitting in Yecheng, and he is a backbone-like existence.

And this place in Yecheng, Cao Wei has been in business for thirty years, not to mention the deep roots, at least it is flourishing. It seems empty, but if Cao Ei comes forward in person, it is not that the Yecheng family will not be able to muster one or two thousand private soldiers to come out and defend the city for Cao Wei.

With the city defense of Yecheng, if there are 10,000 or 20,000 people defending the city, it is enough to hold on until Sima Yi withdraws his army to save him.

On the contrary, the army that went to attack could not capture Yecheng if it advanced, and if it retreated, it would be blocked by the Wei army in Hanoi County. The pure ones are looking for the dead.

This is the real reason why Zhuge Liang is unwilling to implement this strategy that seems to have great benefits, but the actual risks are high.

Compared with this kind of risky behavior, Zhuge Liang is more inclined to take it step by step and walk down-to-earth, first take Yanzhou, then capture Hedong, and then go north in one fell swoop, attack Hebei with the strength of the whole country, and destroy Cao Wei.

And once Cao Wei is destroyed, the remaining Eastern Wu will be much easier to manage, and the regime in a corner will never live long.

Even if you don't use soldiers, just as time goes by, the gap between each other's national strength will become bigger and bigger, and in the end, it will be just a gesture of effort.

This is the royal route of Zhuge Liang's plan to rejuvenate the Han Dynasty.

Of course, this discussion is only limited to Zhuge Liang and Zhang Xi, and the communication between them is also the top secret information of the Han Dynasty, at least Meng Da, Zhang Yi, Liu Yin and others on the front line, in fact, they don't know that Yecheng is empty now.

Maybe Meng Da guessed a little, after all, Meng Da still has a strategic vision, he can calculate it somewhat, and now the troops around Yecheng have been almost mobilized, but no matter how bold Meng Da is, he will not guess that Yecheng is now empty Therefore, in Meng Da's eyes, he can see the possibility of a sneak attack on Yecheng, but this risk, Meng Da is also very clear in his heart.

Meng Da wants to make a career and benefit his children and grandchildren, but he is not the kind of person who gives his life for credit. Being able to work the official road of Taihang is already the result of Meng Da's change of mentality over the years.

And the risk of sneaking up on Yecheng is much higher than blocking people on the official road in Taihang, I don't know how many times, it is completely a practice of nine deaths.

Therefore, the battle in Hedong County, as Zhang Xi took the initiative to retreat to Mengjindu, Qin Lang's rat thrower once again fell into a stalemate.

At the same time, the war situation in Yanzhou finally changed.

The first change lies in the southern border of Chen Liu.

After successively stabilizing the situation in the southeast of Yanzhou, Xu Shu finally led his troops north and approached Yongqiu County, where Sima Yi was located.

At this time, Sima Yi had already passed the gap period during this period and readjusted his defensive line.

The current Sima Yi, with a total of 60,000 soldiers at hand, faced the 120,000 infantry cavalry coalition army on the opposite side, and simply put on a posture of stubborn defense.

Yongqiu County is also a big county seat in Chenliu, but in the final analysis, this place is just a county seat after all, and it is impossible to accommodate 60,000 people in the city.

And from the perspective of defense, shrinking all the soldiers to the city to defend is the next choice, and when defending, it must be both inside and outside, echoing each other, which is the real effective defense.

Therefore, Sima Yi assigned his subordinates.

He led 20,000 soldiers to defend Yongqiu City, and then divided 30,000 troops to Chen Tai, asking him to set up a camp group twenty miles west of Yongqiu City to respond to the guards of Yongqiu City.

And the remaining 10,000 people, Sima Yi handed over to Cao Shuang, and asked him to set up a camp in the rear position on the northwest side of Yongqiu City as a receiving force.

In peacetime operations, Cao Shuang does not need to send troops, but in case of a strong attack by Shu thieves and there is a danger of being breached, Cao Shuang will immediately lead troops to rescue and stabilize the defense line.

A simple triangular defense-in-depth system was thus established.

Next, it's up to Xu Shu to deal with it.

As for Xu Shu, after leading an army of 120,000 troops to advance to thirty miles outside Yongqiu City, he immediately set up camp, and at the same time sent Deng Ai as the front and led 10,000 troops to tentatively attack Yongqiu and figure out the defense system of Yongqiu.

Xu Shu was not careless, he knew that with Sima Yi's ability, he would inevitably take advantage of his efforts to stabilize the southeast border to rebuild the defense line, so he had the practice of letting Deng Ai attack tentatively.

The reason why Deng Ai was chosen was because Deng Ai was calm enough and his strategy was outstanding, and he should be able to figure out the strategic layout that many ordinary generals couldn't see when he went to attack tentatively.

And Deng Ai lived up to his expectations and brought back the information he needed to Xu Shu.

Not only the strength of Chen Tai's battalion, the direction layout, and even Cao Shuang's camp at the back, Deng Ai also speculated by calculating the difference in strength and the reconnaissance of the scouts.

To a certain extent, Zhuge Liang's statement is true, even if Xu Shu has no experience in commanding a large army, it still does not delay him from leading the main force of the Northern Expedition.

Xu Shu only needs to be able to use Deng Ai, Kou Feng, Guan Ping, Hu Zun and others well.

According to the information transmitted back by Deng Ai, Xu Shu immediately responded.

First of all, he divided 30,000 troops, let Kou Feng lead them, and went to join Deng Ai's department, and the two of them also deviated from the main camp for twenty miles and set up another camp.

The purpose of the two of them is to besiege Chen Tai's camp, if they can break through this camp, of course it is better, if not, contain the forces of this camp, and don't let him have a chance to return to Yongqiu.

Secondly, he ordered Pang De to lead the cavalry around the rear and march to the northwest of Yongqiu, looking for the corresponding camp set up by the Wei thieves in the rear, also not seeking to break the enemy, but only to contain it.

Third, send an envoy to inform Hu Zun in Liang State, so that he does not have to worry about Lu Xun on the flank, and lead his troops to the junction of Liang State and Jiyin County to contain Jia Kui, who lives in Dingtao.

Xu Shu wanted to use this method to cut off all the minions of Sima Yi's defense, and then personally led 60,000 troops, with Guan Ping as the vanguard in the front, to attack Yongqiu City.

Xu Shu wants to fight Sima Yi in this Yongqiu City in the way of "the king sees the king!!
