The Liaodong Iron Cavalry looked menacing, but in the face of the firearms of the Qin army, it was about to collapse at the touch of a button, and Gongsun Du was also ashamed in the face of such an outcome. However, it is impossible for him to give up the Yan State just like that, like his Gongsun family in Liaodong, they have been the hegemon for a long time, how can he succumb to Cao Xuan now.

Don't eat in the face of Cao's soft and hard. Gongsun Du was also in a hurry, and finally made an amazing move, his move probably means that in the face of Cao Xing, can't he be provoked and hidden?

Although it is true that he can't fight the Qin State militarily, but he no longer attacks, and blindly defending, Gongsun Du directly withdrew all the garrisons outside and concentrated in his own Liaodong County.

Using the strategy of clearing the wilderness with strong walls, resolutely not allowing the Qin army to step into his Yan State for half a step, Chen Hu carried out several tentative attacks, but the final effect was not very good, the reason was not because the defense of the Yan State was too strong, but because some local clans of the Yan State did not support the Qin State and did not welcome the arrival of the Qin State.

In the interior of the Yan Kingdom, it has even reached the point where the grass and trees are all soldiers, Jinyi Wei reported a series of intelligence, Cao Xing carefully looked at the above situation, and finally analyzed a result with many strategists, that is, the reason why the Yan Kingdom can be established is all because of the Gongsun family, which is the first family and the first family of the Yan Kingdom.

Today's Yan Kingdom is similar to Yuan Shao's Zhao State in the past, why Yuan Shao gained a foothold quickly, why did he develop and grow, it was all because of the support of the family, and Yan Guo was the same.

The family has important resources in this world, such as knowledge and public opinion, etc., under their instigation, even most of the people of Yan have begun to resist the arrival of the Qin army, once they lose the hearts of the people, it can be described as difficult to move an inch, just like Cao Cao in Xuzhou in the early years, although Cao Cao has been trying his best to appease Xuzhou in recent years, reducing a lot of taxes in Xuzhou, but the impact it has caused has not been completely eliminated.

Therefore, if there is no support from the people, even if the place is forcibly unified by force, nothing good will be obtained.

Thinking of this, Cao Xuan pondered for a long time, and finally he recruited a person, and that person was none other than Xu Shu.

In the early years, Xu Shu had been fighting against Zhao State, and he had worked hard and made great achievements, and now Cao Xing has launched a full-scale attack on Zhao State, not using Xu Shu, but letting Xu Shu train well in Luoyang.

Cao Xuan found Xu Shu and opened the map directly in front of Xu Shu, this is the border map of Yan Kingdom, Cao Xing's finger pointed to the map of Yan Kingdom, and kept saying something to Xu Shu, and Xu Shu nodded again and again after listening to it.

"Wang, please rest assured, my teacher also taught me before, don't be complacent because of the existing knowledge, this world is still very big, and there are still many things I don't understand, so when I was in Luoyang, I humbly asked Fengyun and others for advice, the plan you said, in fact, I thought about it a long time ago, and it seems to be just right to use it in Yan Country now!"

After hearing this, Cao Xing was overjoyed, and that day Cao Xuan directly announced an order, that is, the twelve cities on the border defense line of Yan State, and all the troops in them were dispatched by Xu Shu. Xu Shu was appointed as the governor of the capital.

The metropolitan governor usually holds heavy troops, just like the previous generals, but Cao Xuan also gave Xu Shu a great convenience, that is, Xu Shu not only holds military power, but also the county commanders and others in the more than ten cities must try to cooperate with Xu Shu, especially economically.

As a result, Xu Shu basically became the most powerful person in the northeast of the Qin State.

For Cao Xing's order, in fact, there are many people in the Qin State who are puzzled, it is necessary to garrison in the east and defend against the Yan State, but why did Xu Shu still give so much convenience, this is a little unreasonable.

There are many officials in the Qin State who don't understand, and Gongsun Du and others in the Yan State are even more confused, they just know one thing clearly, that is, Xu Shu is stationed in the east, he must be here to defend against them, they must be prepared, Gongsun Du's strategy is still the same as always, he will not take the initiative to provoke Xu Shu, but if Xu Shu wants to enter the Yan Kingdom, there is no way.

And after Xu Shu arrived, his attitude towards Yan Guo was also a little subtle, he would not take the initiative to provoke, nor would he take the initiative to attack, he would take soldiers and horses to train every day, and that would be it. Seeing this, the people of Yan Kingdom gradually put their minds at ease, maybe Xu Shu just came to garrison everywhere, and did not have any special intentions.

And after Cao Xuan ordered Xu Shu to garrison the east, there seemed to be no other action. At least for Yan Guo, Cao Xing set his sights on the north.

Yuan Shao's two sons are still running away, Yuan Xi and Yuan Shang, these two people have not left too much grandeur in history, and it can even be said that because of the perennial intrigue, Yuan Shao's two waste sons do not pose any threat to Cao Xing, but because their identities are somewhat special, if he is used by someone with a heart, it will still bring a little trouble to Cao Xing.

In order to get rid of the troubles forever, Cao Xuan wanted to send troops directly into the north, and these two people were arrested and killed. However, Cao Xing has some troubled things, Yuan Shao established the Zhao State before, and there is still more or less contact with Karasuma in the north, and there seem to be people in Karasuma who support Yuan Shao, and this time, Yuan Xi and Yuan Shang have no way to go, and they came directly to the north, and they are naturally accepted by the people over there, and the people who accept them are called Badun.

It seems that Badun is one of the Zuoxian kings in their tribe, and his power is also very great, with him, maybe Cao Xuan wants to take the lives of these two people, and there are some difficulties.

This time, Cao Xuan was a little entangled, and he had just finished fighting with Zhao State, so he had to ask Cao Xuan to personally send troops north with his troops and fight another battle with Karasuma.

Cao Xuan couldn't make up his mind for a while, so he threw this question to his many strategists, anyway, Cao Xuan had only one purpose, that is, he had to bring him the heads of Yuan Xi and Yuan Shang.

Many of these advisors suggested to Cao Xuan that Karasuma could be forced to hand over the two through diplomatic means.

It was also suggested that the two of them could be assassinated directly by using the method of treachery, so that everything would be resolved.

Cao Xing couldn't help frowning when he listened to these suggestions, although these suggestions seemed to be very reliable, but the feasibility was a little difficult.

Through diplomatic means, Qin and Karasuma did not establish any diplomacy before, and now the first time to establish diplomacy is to find someone else, which seems to be a little inappropriate.

Through assassination, it is more difficult, first of all, you have to find the assassin, there are still some differences between the appearance of the Central Plains people and the Karasuma people, and the style of life is even more different, you send a Central Plains assassin to enter other people's camps in a grand manner, I am afraid that they have not yet come into contact with the target person, and they have been stopped by others.

But just when Cao Xuan was distressed, suddenly Jia Xu jumped out and said to Cao Xing: "King, in fact, I have a plan, that is, to wave my troops north now to take Karasuma, at least kill the king Zuo Xian who supported Yuan Shao!" ”

Jia Xu said this. Everyone was terrified. Jia Xu is Cao Xing's mastermind, how could he come up with such a brainless idea, you must know that Cao Xuan had just finished fighting with Zhao Guo and had a fight with Cao Cao. The soldiers of the Qin State have suffered a lot of losses, and now they have to send troops to the north to fight against people from other tribes in the barren land, isn't this looking for death?

How could such a plan come from Jia Wenhe's hands, many people are a little puzzled.

However, hearing Jia Xu's words, Cao Xuan narrowed his eyes, waved his hand, stopped the hustle and bustle of everyone, and motioned for Xu to continue.

And Jia Xu also cleared his throat, and then said to Cao Xing, the reason why he said this, firstly, is because it is precisely because they have just destroyed the Zhao State and fought another battle with Cao Cao, and some people feel sleepy, so Karasuma definitely did not expect that Cao Xuan would fight him now, if Cao Xuan sent troops at this moment, he could catch Karasuma off guard.

Second, if Cao Xuan does not send troops now, then he can only recuperate, and when the soldiers are full of food in the coming day, he will send troops north, after all, Karasuma is always a hazard, and it must be eradicated to ensure the stability of the north, but at that time, Cao Xuan wanted to eradicate Karasuma again, and there were some difficulties.

Because Cao Xuan not only has to deal with the people in the north, but more importantly, he has to deal with the people around him, Cao Cao is eyeing him in the south, if he waits for Cao Xing's army to leave, Cao Cao will definitely attack from behind, and Cao Cao at that time also got a long rest. His soldiers and horses will definitely be elite soldiers, and under a sudden attack, I am afraid that the Qin State will be in danger of losing its territory.

In the end, Jia Xu concisely pointed out the center of his time, that is, the speed of soldiers. When Jia Xu finished saying what he said, all the advisers and generals stopped talking, Jia Xu's plan seemed very bold and dangerous, but if you think about it carefully, it is also very reasonable.

The surrounding strategists heard Jia Xu's words, their faces were a little moved, but Cao Xing frowned deeper after hearing this, how could he be familiar with Jia Xu's remarks, Cao Cao seems to have encountered such trouble in history, whether to go north to attack Karasuma, many strategists were against it at that time, only Guo Jia stood up and supported his statement, which seems to be similar to Jia Xu's statement now, and finally Cao Cao waved his army north, and successfully defeated Karasuma.

As the so-called soldier is fast, Cao Xing just thought about it for half an hour, in this half an hour of time. The only thing Cao Xing did was to inspect his military camp, inspect his soldiers, and see that his soldiers' faces were all filled with smiles after winning the battle, Cao Xing was sure that his soldiers could fight again, so he did not hesitate, and directly issued the final order, and immediately waved his army north.

With Chen Hu as the vanguard, he led all the soldiers and horses in his department, plus the Iron Floating Tu, to attack the northern Badun.

Only three days later, Cao Cao also sorted things out in Yecheng, and was just about to return to the court and return to his Xuchang, but at this time, there was a news from the north.

Cao Xing's army suddenly returned to the north, suffocated Karasuma's station, pulled out nine battalions and eighteen villages, and caught Karasuma off guard.

When he heard the news, Cao Cao felt a little stunned, and Guo Jia's eyes on the side were constantly flashing with strange light.

In the end, Cao Cao and Guo Jia glanced at each other, and both shook their heads helplessly.

"Hahahaha, this Cao sex will really surprise me!" Cao Cao said with a laugh.

And Guo Jia also smiled helplessly, but Guo Jia's heart was very heavy, because from this incident, he could see that Cao Xing definitely had a master by his side, and that person's wisdom was never below him Guo Jia.

When Li Dian and others heard the news, they glanced at each other, and Yu Ban took the lead and said.

"Since Cao Xuan chose to send troops north to attack Karasuma, then Cao Xing's defense around him at the moment must be quite weak, why not take this opportunity and directly catch him off guard!"

Before Cao Cao could speak, Guo Jia stood up and explained, Cao Xing was a preemptive strike, since Cao Xuan dared to lead the troops to attack Karasuma, it means that Cao Xuan was already sure of this matter.

The troops he reserved are definitely not just the superficial arrangement, the soldiers he left behind have more or less unique skills in their hands, which can defend against Cao Cao's attack.

Secondly, whether it was Guo Jia or Cao Cao, they didn't think that Cao Xing would come to play this hand, so at the moment Cao Cao had already let his general Xiahou Yuan return to Xuchang with most of the soldiers and horses.

If Xiahou Yuan is asked to transfer the large army back now, and tell those soldiers that they are going to fight again, the soldiers will definitely complain, after all, it is not easy for him to go back, and he will be brought back to fight, and he will be played by Cao Cao, there must be a lot of resentment in his heart, and under the low morale, forcibly attacking will only backfire.

So in the end, Cao Cao also waved his hand and said with a smile: "That's it, this time we have the opportunity to fight and capture Yecheng, this is already a great feat, you can't be too greedy, since he Cao Xing, out of this strange scheme, waved his army north, and forcibly beat Karasuma, that is also his ability, I won't harass him, because he Cao Xuan wants to completely conquer Karasuma, I'm afraid it's not so simple, I just don't know if Cao Xing can resist this time!" ”

After Cao Cao said this, he laughed again, and then gave the final order to withdraw his troops, leaving enough defensive troops in Qingzhou, Jizhou, and then the others returned to Xuchang with him.

Up to now, Cao He and Cao Cao have basically divided Yuan Shao's territory, and the three major princes in the north seem to be only two major princes. Perhaps in the near future, these two powerful princes will also have a fierce collision.
