Xu Shu received a message from Deng Ai, and he didn't have any carelessness, and immediately sent Zhang Wei to lead his troops to tentatively attack Yongqiu County.

There were not many troops, but not more than 10,000 people, and the intensity of the attack was not high, so only one reconnaissance attack was carried out, the purpose of which was to observe the number and morale of the defenders, so as to judge the movement of the Wei army.

Of course, it would be better if it could be determined whether Sima Yi was still in the city.

As a result, Zhang Wei was suppressed by the defenders' very fierce bows and arrows, and the attack was blocked for a while, and the Wei army's will to fight has not changed significantly compared with the previous days.

As for Sima Yi. Zhang Wei saw Sima Yi himself appear on the Yongqiu city wall, standing under his big guard, and personally commanding the battle.

This result somewhat surprised Xu Shu.

One thing to say, because Xu Shu knows Deng Ai's ability very well, so at the beginning, his judgment of Deng Ai was also preliminarily recognized, at least judging from Deng Ai's description in the military newspaper, it is indeed possible that the Wei thief is playing bluff, but in fact, the trick of retreating.

It's just that once Sima Yi really abandons Yongqiu, it will have an immeasurable impact on the entire Yanzhou battle situation, and it must be treated with caution.

Therefore, Xu Shu sent Zhang Wei to launch a tentative attack on Yongqiu.

But now, it turns out that not only has the morale of the Wei defenders not changed, but Sima Yi is also still in Yongqiu City, and this is the confrontation and siege that Zhang Wei has seen with his own eyes for so long, as one of the front-line generals, Zhang Wei has no reason to mistake the enemy commander Sima Yi.

And the appearance of Sima Yi also made Xu Shu begin to wonder whether the Wei thief really wanted to retreat, or if he had other plans.

If it is really as Deng Ai said, the Wei thief is going to withdraw his army. Let's not talk about what the strategic purpose of Wei Jun is to do this, at least Sima Yi, as the commander, is unlikely to stay and break the queen, right?!

How can there be a reason for the commander to break off when he withdraws the army?!

Aren't you afraid that something will happen to the coach and cause the whole army to collapse?!

If there is another plan, what is the plan of the Wei thief?!

Rely on 60,000 men to counterattack the 120,000 infantry cavalry coalition army?!

Caught off guard for a while, Sima Yi still has the possibility of a sneak attack, but now that Xu Shu has ordered to be vigilant and take precautions on all fronts, if the Wei thief counterattacks next time, Sima Yi will not be so easy to succeed.

Of course, those who can't get their hands on it will put it aside first, these two possibilities actually represent the two diametrically opposed ways of dealing with the Wei thief next.

Retreat, or stay.

The Wei army adopts different combat methods, so Xu Shu's side must also prepare in advance, but now, Xu Shu can't judge what the Wei army will do.

There are two possibilities.

In the end, after some thought, Xu Shu finally decided. Hold your ground for the time being.

In addition to the smoke effect caused by Sima Yi's appearance on the tower of Yongqiu City, the biggest reason why Xu Shu chose to stand still was that Xu Shu did not think clearly, what benefits did Sima Yi choose to retreat for him.

Sima Yi's duty is to guard Yanzhou, and if he withdraws, there will really be no place left in Yanzhou.

If it is said that the loss of southern Yanzhou was because Xu Shu quickly broke through Yingchuan County, which caused Sima Yi to be a little caught off guard, coupled with the advance of Wei Yan in the eastern county in the north, Sima Yi was tired of dealing with it on both sides and was unable to do it. What is the reason for Sima Yi's withdrawal from Chenliu now?!

As soon as Chen Liuliu withdrew, Jiyin County and Shanyang County would definitely not be able to hold it, so Sima Yi would have to retreat to Dongjun and Taishan County.

On the side of Kedong County, there is also the Han Forbidden Army under Wei Yan's department fighting, while Taishan County, although it is a holy place of culture and education, it does not have much strategic value.

What the hell do you think this Sima Yi is trying to do?!

Guarding Yanzhou, guarding and guarding, Yanzhou lost one-third, gave up one-third, and finally only one-third was left in hand Sima Yi's battle was like this, Cao Rong could spare him? !

This is also Xu Shu's biggest confusion now, and at the same time, it is also the reason why he can't make up his mind and prepare for the pursuit. Xu Shu really couldn't see Sima Yi's choice to retreat.

But fortunately, Xu Shu is not the kind of person who insists on going his own way, can't figure it out and thinks hard. If you can't figure it out, find a few more people to discuss it with you, in case you can get some inspiration.

Therefore, Xu Shu sent someone to summon Deng Ai and Biqiu Jian overnight to discuss countermeasures.

Especially Deng Ai, Xu Shu now wants to hear what Deng Ai, who was the first to judge that the Wei army was going to withdraw, thought.

There is no need to discuss the issue of the Wei army continuing to stay in Chenliu County, just how to fight and how to continue to fight.

What needs to be discussed now is, from a strategic point of view, where is the necessity of Sima Yi's retreat?!

Don't say it, Deng Ai has also seriously considered this issue.

Although Deng Ai also found it quite difficult to understand, Deng Ai still reluctantly found some reasonable explanations.

"Wei thieves have few soldiers, which is not conducive to long-term holding, and Wei Zhengxi led troops to wreak havoc in Dongjun, and the Wei thieves are in danger. Sima Yi had to surrender Baoer. ”

This is what Deng Ai can think of, a relatively reasonable explanation - Sima Yi may not be able to hold on to Chenliu, and at the same time, Wei Yan also opened up the situation in Dongjun, and Sima Yi chose to withdraw in order to preserve his strength.

But this idea can really only be an idea.

The subjective element of assumption is a bit too high.

First of all, judging from the counterattack launched by Sima Yi last time, although the Wei thief has always adopted a defensive attitude in Yongqiu, it is not without the strength of a battle, and it is really unconvincing to say that Sima Yi can't hold on in Yongqiu.

Secondly, no one knows the specific situation of Wei Yan's battle in Dongjun now.

Wei Yan himself was a lone in-depth battle, cut off contact with all directions, and Xu Shu's side could only judge the effectiveness of Wei Yan's attack through some changes in the battle situation.

For example, Jia Kui in Jiyin County gave up the defense of the outer county towns and concentrated his troops to defend Dingtao, and it can be basically judged that Wei Yan did a good job in Dongjun, which caused Jia Kui to not dare to divide his troops to the north to counterattack, so he could only be trapped in Dingtao to protect himself.

But more cases, Xu Shu can't judge.

Therefore, at this time, whether Wei Yan has threatened Sima Yi's back road, or whether Sima Yi will take advantage of this situation of unobstructed intelligence to design for himself, pretending that Wei Yan has threatened his back road, it is uncertain.

Therefore, for Deng Ai's judgment, Xu Shu can only say that this is a direction that can be thought about and speculated, but there is no reasonable evidence to support it.

And Biqiu Jian also put forward another reason for Sima Yi to withdraw from the army.

"Wei-Wu Alliance, Sima Yi chose to withdraw this time, or did he want to lure us and others deep into Yanzhou, and then let Eastern Wu attack our army and attack it from both sides?!"

Well. Not to mention, this kind of possibility is really there, at least when Xu Shu and Deng Ai heard it at first glance, their faces were still solemn.

Sima Yi had the courage to devise this kind of strategy, and once the Han army penetrated deep into the hinterland of Yanzhou, Lu Xun, who stayed in the Peiguo area, suddenly led his troops north, and Zhuge Dan, who was stationed at the border of Xiapi, led his troops westward into an encirclement network.

But, if you think about it carefully, this possibility is even lower than Deng Ai's conjecture.

Deng Ai's conjecture is still pinned on the results of his family's actions, with Wei Yan's ability, it is not impossible for him to stir up a world in Dongjun.

But Qiu Jian's conjecture is to hope that Wei and Wu will work together to really, which is a joke.

In these years, who doesn't know the style of doing things in Eastern Wu, with Sima Yi's style of employing troops, how could he be willing to keep the risk to himself and pin the hope of breaking the enemy on the army of Eastern Wu?!

This possibility is too low, unless he Sima Yi is at the end of his rope, he will not pin his hopes on the capricious Dongwu.

However, it is not that Biqiujian's statement is useless, this is also a line of thought.

At least Xu Shu began to think about it, is it possible that Sima Yi deliberately withdrew from the three counties in central Yanzhou, on the one hand, to attract the Northern Expeditionary Army of the Han Dynasty to continue to go deeper, and on the other hand, to use several counties in the east of Yanzhou to drag the Eastern Wu army into the battlefield?!

As for the kind of problem that Dongwu is not enough to take advantage, if Sima Yi really abandoned Shanyang County and Jiyin County, Zhuge Dan in Xiapi may not be able to sit still.

And if Hu Zun leads his troops north to occupy Jiyin County, I am afraid that Lu Xun will also have to enter the Liang State inch by inch, which is not impossible.

As long as one is not handled well, it is really possible for Sima Yi to directly involve the army of Eastern Wu in this Yanzhou War.

At that time, even if Han and Wu did not fight directly, Xu Shu would have to divide his troops to guard other places as he had just done when he first entered Yanzhou. In this way, the forces used to besiege Sima Yi will be further thinned.

If you do this, it is not impossible to repeat a state of three kingdoms in Yanzhou.

And this is also the way Sima Yi is most likely to hold Yanzhou.
