As the saying goes, the general will be outside, and the king's order will not be affected.

Sima Yi finally decided to adopt his own strategy without consulting the imperial court.

On the one hand, the current situation makes Sima Yi really unable to wait for the back and forth of the imperial court and the edict of the Son of Heaven.

On the other hand, as the supreme commander of the Battle of Yanzhou, Sima Yi believed that he had this responsibility and this responsibility to make strategic changes that were most in line with the situation on the front line.

Sima Yi is an old fox and has ambitions, but to tell the truth, he will also be a responsible person, at least at this stage, Sima Yi's ambitions have not yet fermented, and he is still a loyal minister of Great Wei.

Therefore, although Sima Yi knew that even if he finally held the Yanzhou area on the south bank of the Yellow River, he would be held accountable after returning to the dynasty, and the responsibility was not small, he still made such a decision.

Because this is what Sima Yi can think of, to ensure that the main army is not lost to the greatest extent, and at the same time have the greatest certainty of the strategy of being able to defend a part of Yanzhou.

After making a decision, Sima Yi will not think about other things, but will only make commands and arrangements around this strategy.

For example, Cao Shuang came to force him to talk again, and was directly scolded back by Sima Yi.

Of course, Cao Shuang would not agree with Sima Yi's unauthorized change of strategy, and this time, Cao Shuang was really not out of selfishness, he really felt that Sima Yi's choice to abandon Chen and retreat to Dongjun was too conservative.

Yes, the battle in Yongqiu is a little tense, but it's not that it can't be held. It would be too hasty to abandon Chen Liuliu in this situation.

If you continue to retreat all the way like this, I am afraid that Great Wei will lose the entire Yanzhou.

Again, Cao Shuang also knew very well that Sima Yi did not know about it, and even if he did, he would not easily agree.

Therefore, at this time, Cao Shuang, the protector, must stand up against it, not only because he opposes this strategy, but also because it is his duty.

But Sima Yi told Cao Shuang that this was a decision he made as a front-line coach.

Either Cao Shuang went to the imperial court, and then asked for an edict to deprive himself of military power and command, or he obeyed orders.

After all, it is wartime, and there can only be one voice in the army.

In the end, Cao Shuang still didn't have the confidence and courage to deprive Sima Yi of his military power on the spot, so he could only choose to shut up temporarily, but returned to his room to write a note, reported the matter to the Son of Heaven, and asked the Son of Heaven to decide.

Sima Yi didn't have time to talk to Cao Shuang now, and he began to make tactical adjustments around his new strategy.

First of all, Sima Yi sent someone to Jia Kui of Dingtao to deliver a message, asking him to abandon Dingtao, lead the army to the north, and attack Puyang, the county of Dongjun.

According to the description in the military report sent by Guo Huai, the Shu thieves gathered more than 30,000 troops on the line from Yanjin to Suzao, and compared with the early Dongjun battle report, Sima Yi keenly found that the Shu thieves basically did not leave much troops to defend in Puyang and Dong'a.

The combined strength of these two places should not exceed 5,000 troops.

Therefore, Sima Yi needed Jia Kui to lead 15,000 men north to attack Puyang after abandoning Dingtao, recover this important town in Dongjun, and connect Dong'e and Taishan counties to establish a defensive line on the spot.

Secondly, on the side of Yanjin and Suojube, Sima Yi ordered someone to give Jiang Ji in Yanjin an order, ordering him to send troops to support Suojube at all costs, firstly, to prevent Sujube from really falling, and secondly, to keep the Shu thieves on the line from Sujube to Yanjin.

Of course, Sima Yi can see that the Shu thieves are playing on the front line of sour dates and Yanjin to encircle the point to help, and Sima Yi also needs to let the Shu thieves stay on the front line of sour dates and Yanjin, so let Jiang Ji cooperate with the Shu thieves, and let them surround the point to help.

After the two military orders from other places were issued, Sima Yi sent people out of the city to contact Chen Tai, and asked Chen Tai to cooperate with him, and five days later, launch a counterattack against the camp of the Shu thieves.

This counterattack not only requires Chen Tai to take the initiative to send troops to counterattack, but Sima Yi himself will also be killed from Yongqiu City, and he must effectively kill the Shu thieves.

Only in this way can the Shu thieves not dare to besiege Yongqiu City too ruthlessly, and Sima Yi will have the opportunity to deceive Xu Shu by hiding from the sky and the sea, and withdraw his army to besiege Wei Yan of Sour Zao.

Sima Yi made all the tactical adjustments and preparations. Five days later, the Wei army, which was inside and outside Yongqiu City, suddenly launched a full-scale counterattack against the Shu thieves.

This counteroffensive raid really caught Xu Shu off guard.

No way, Sima Yi, the old turtle, since he retreated to Chen Liu, in the nearly three months of offensive and defensive battles, he has always been unable to shrink, relying on the city defense to hold on Who would have thought that this guy who has always been a shrinking turtle would suddenly launch a counterattack.

Therefore, this counterattack caused a lot of losses to the Han army.

Guan Ping and Guan Xing in front of Yongqiu City, caught off guard, were directly attacked by Sima Yi and had to lead the defeated troops to retreat, and united Zhang Wei in the rear of the two, and the three of them together barely held Sima Yi's attack.

And Sima Yi was also very cunning, after breaking through the two camps, he did not storm Zhang Wei's camp, and after finding that the attack was blocked, he retreated to Yongqiu City before the main force of the Chinese army led by Xu Shu came to help.

However, this raid also caused more than 4,000 casualties to the Han army.

On Chen Tai's side, although his surprise attack was also effective, the results were not as great as Sima Yi's.

After all, the opponent is not the same.

It is not difficult for Sima Yi to bully Guan Ping and Guan Xing, but if Chen Tai wants to crush Deng Ai, it is purely thinking too much.

Of course, Chen Tai's surprise attack did catch Deng Ai off guard, but Deng Ai's response speed was very fast, and after he found out that Chen Tai took the initiative to attack, he immediately went to contact Kou Feng and Biqiu Jian, and the three of them cooperated with each other and quickly formed a joint force. Although more than 2,000 casualties were paid, it was not broken through by Chen Tai, and Chen Tai also suffered more than 1,000 casualties.

However, on the whole, this wave of raids by the Wei army was still very effective, which directly led to Xu Shu ordering all battalions to suspend the attack and strengthen their vigilance in order to deal with Cao Wei's possible surprise attack again.

After all, if Sima Yi wanted to use counterattack instead of defense to disrupt the offensive rhythm of the Han army, he would not attack only once.

In the next two or three days, Sima Yi will inevitably attack again.

And Sima Yi's side wants Xu Shu's reaction, although it doesn't take much time, but the time difference of two to three days is enough for Sima Yi.

The next day, Sima Yi began to repeat the old trick, set up more flags, ordered the soldiers to strengthen the frequency of patrolling back and forth on the city wall, and at the same time made a lot of noise in the city, so that Xu Shu outside the city thought that Sima Yi was preparing for the next attack. But in fact, Sima Yi had already begun to order the withdrawal of troops.

It can be said that Sima Yi's approach, although it may not be new, does work well, at least Xu Shu was indeed fooled.

And in the Han military camp, the only person who saw the flaws was Deng Ai.

It's not that Deng Ai is smarter than Xu Shu, it's purely that Deng Ai's opponent Chen Tai is not as good at acting as Sima Yi.

Sima Yi's withdrawal in Yongqiu City, even if it is put in front of Deng Ai, Deng Ai will also be fooled, but Chen Tai's withdrawal in the camp outside the city is somewhat not strict enough.

Chen Tai also followed the routine taught by Sima Yi, and sent military envoys to pretend to strengthen the connection between the various camps, and then concentrated his forces and made it look like he was going to prepare for a second attack. But in fact, it was gathering the soldiers, packing up their things, and preparing to run away.

Originally, Deng Ai didn't see any flaws, and he was also discussing with Kou Feng and others how to defend next time, but Chen Tai forgot an important thing - cooking smoke.

Sima Yi arranged the withdrawal of troops in the city, and with the obstruction of the city wall, the Han army could not peek into the reality of the city, and could only judge the number of enemy troops by the change of the military flag at the head of the city and the number of patrols on the city wall.

It's hard to judge accurately.

But Chen Tai was camped in the wild, and there were too many ways to judge the number of troops in these camps.

Cooking smoke is a good way to do this.

The soldiers who camped in the field could only obtain cooked food through picnics, and the amount of cooking smoke often determined the number of troops in the battalion to a certain extent.

Deng Ai soon discovered that as Chen Tai gathered troops, the amount of cooking smoke in several camps near Chen Tai's main camp not only did not increase, but tended to decrease. Wei Jun can't stop eating, right?!

During the march and battle, the soldiers can still have an understanding of the counterattack and decisive battle when they eat cold food, and if you don't give the soldiers some hot food and meat, are you Chen Tai really afraid that when you fight in a few days, the soldiers will not contribute to your work, or simply mutiny? !

Anyway, Deng Ai thinks that Chen Tai should not be stupid to become this virtue. Therefore, there are probably not as many soldiers in the camp as it appears on the surface.

In other words, there is a good chance that the Wei army is withdrawing!!

After realizing this possibility, Deng Ai sent someone to contact Xu Shu in the main camp, and at the same time found Kou Feng and Biqiu Jian to discuss whether to launch a tentative attack on the camp of the Wei army?!

And this point is obviously very much for Kou Feng and Biqiu Jian, both of whom are not afraid of things.

And this hit suddenly made Chen Tai further trapped.

It's not that Chen Tai's main camp is easy to fight. On the contrary, the raiding troops led by Kou Feng encountered a fierce counterattack from the Wei army, causing Kou Feng not to dare to attack, and after a wave of temptation, he led his troops to retreat.

But the Wei army did not go out of the camp to pursue.

As an army that intends to launch a counteroffensive in a day or two, and suddenly encounters a tentative attack by the enemy, it refuses to chase it out, so it is not afraid of hurting the morale of the army?!

There's definitely something greasy in this.
