Cao Cao is very distressed at the moment, when Guan Yu surrendered to himself, he made an appointment with himself, but it was just a temporary surrender, and once he learned of Liu Bei's whereabouts, he had to return to the other party.

At that time, I didn't pay much attention to this agreement. When Liu Bei was defeated, life and death were uncertain, if he died, would Guan Yu still be able to get him underground? Even if Liu Bei was alive, Cao Cao believed that as long as he treated Guan Yu kindly, gave him great favors, and entrusted him with a high position, he would inevitably change his mind and serve himself wholeheartedly.

However, all the means he can come up with to win people's hearts have been used one by one, but Guan Yu is still like a rock and has never really surrendered to himself. Although Guan Yu's attitude towards himself was respectful, he never stopped probing Liu Bei's traces, and never dispelled his desire to return to Liu Bei's account.

Now that Liu Bei's whereabouts are known to Guan Yu, he immediately came to ask for his resignation, and he didn't drag his feet at all.

In the battle of Guandu, Guan Yu made a lot of contributions. In Guan Yu's opinion, he no longer owes Cao Cao anything, and now that he knows his brother's whereabouts, it is naturally time to leave.

Let Guan Yu go? Of course, Cao Cao was reluctant, not to mention that he would send troops to Jingzhou sooner or later, and letting Guan Yu return to Liu Bei's side was tantamount to returning to the mountain. Just because of Guan Yu's ability, Cao Cao was unwilling to give it up.

Such a loyal and brave general is simply something that can be met but not sought, how can it be easily let go?

But even if you are reluctant, what should you do, find a way to push? It seems that there is no reason or excuse to shirk at all.

When Guan Yu came to find him for the first time, he pretended not to be there and asked the doorman to stop Guan Yu directly outside the mansion. But Guan Yu will never be the kind of person who will die easily, the first time he fails to see someone, there will definitely be a second and third time, besides, can he still avoid Guan Yu from now on?

Just when Cao Cao was having a headache about Guan Yu, an urgent report came from the north.

Xianbei army Koubian!

As soon as Cao Cao heard the news, Guan Yu immediately left everything behind.

You Guan Yu is important, but can it be heavier than the border or? The border is attacked by foreign races, which is a great disaster!

Since the death of the first generation of male lord Tan Shihuai, Xianbei has been in a slump, but he has not harassed the border much. Why is it unusual, this time?

According to the border report, Xianbei gathered about 70,000 to 80,000 people, and the soldiers had pointed directly at Daijun.

Cao Cao did not dare to slack off in this regard, and hurriedly convened all the civil and military forces to discuss.

When everyone learned the news of Xianbei's invasion from Cao Cao, everyone had a solemn look on their faces.

80,000 Xianbei is really a lot, enough to form an extremely serious border trouble.

If one is not handled properly, a large number of people will be displaced at the border gates.

The question is, what to do now, according to the Great Wall? Or take the initiative to fight against the enemy outside the Great Wall?

The controversy is very fierce, even for peerless ministers such as Xun Yu and Guo Jia, their opinions are not always unified. Now these advisers were divided into two groups, one of which suggested leaning on the Great Wall to fight back against the invading enemy. The other group of people believed that the Han army should take the initiative to attack and teach the Xianbei people a painful lesson.

Since the Battle of Guandu, Cao's army has fought one after another, and it has long been exhausted. Although after more than three months of recuperation and adjustment, the army's combat strength has recovered slightly. However, the vitality of the army consumed in the course of a long campaign can not be replenished by a few months of recuperation.

If a large-scale war is waged with Xianbei now, I am afraid that the morale of the army may not be high, and it may not be able to gain an advantage in the war.

But do you want to take the initiative to avoid the war? During the period of Tanshi Huai, Xianbei repeatedly robbed the border, the grain was robbed, the men were killed, and the women were taken captive, resulting in the border land, which was really a miasma.

Although the current Xianbei is divided into several parts, the strength is far less than that of the Xianbei in the Tanshi Huai period. But now the situation in Dahan is also very chaotic, and it is not the same as it was a few decades ago. If the Han army does not have any counter-fire or other actions for Xianbei's attack, it is estimated that the border pass will never be peaceful in the future.

To fight, or not to fight, that's the question. If there is a war, the situation may not be favorable; If you don't fight, maybe you will set off an alien Koubian ** again.

War! Cao Cao finally made the decision to attack. After the elimination of the Yuan clan, the entire north is unified by me, the princes of the world, with my strength as the strongest, if I don't fight, who can fight! As a general, it is my duty to protect the land and the people! Even if the morale of the army is a little low now, and the soldiers have not yet come out of the fatigue period, but no matter what, I will not be afraid of battle!

Cao Cao decided to organize an army of 100,000 and fight with Xianbei.

————————————————————————————————

Guan Yu was tidying up his things in the mansion, and the last time he asked to see Cao Cao to no avail, he knew that Cao Cao didn't want to let him go.

Even so, I can only say goodbye without saying goodbye. Guan Yu plans to seal the gold, and whatever Cao Cao gives will not be accepted. Then he took the two ladies and a few servants and left quietly.

Therefore, Cao Cao convened the generals to discuss the matter, but he did not go.

Just when Guan Yu was almost ready, someone suddenly came to report, and Gao Shun, the general of Pingdong, asked to see him.

Gao Shun? He doesn't have much friendship with me, and he doesn't have much contact with him on weekdays, so why did he suddenly come to me?

Could it be that Cao Cao has allowed me to leave? Guan Yu's heart moved, and he hurriedly asked Gao Shun to come in.

"Yun Chang, the lord is about to go on an expedition, you should prepare quickly and go with the army!" As soon as Gao Shun entered the door, he said loudly to Guan Yu.

When Guan Yu heard this, he was immediately interested. This guy didn't come to let me go, but let me continue to fight for Cao Cao. At that moment, Guan Yu looked a little displeased, and said in a deep voice: "In the past, I once said that I would leave when I found my brother's whereabouts. I have made meritorious contributions in Cao Ying in the past, and now I know that my brother is in Chuyang, and it is the time to leave, and An can serve the Cao family again? ”

After a pause, Guan Yu said again: "Besides, Yuan Shao is dead, now is the time for Cao Gong to reorganize his troops and recuperate, instead of recklessly fighting and recklessly. ”

"Cao Cao is going to send troops again? Could it be that he already wants to enter Jingzhou? If that's the case, I'm afraid he won't let me go. While talking to Gao Shun, Guan Yu was also secretly thinking in his heart.

"Definitely! The lord is by no means vain in raising a war this time, but he is forced to do so. Gao Shun explained to Guan Yu, "Besides, the general's battle this time is not for the Cao family, but for the people of the world!" ”

Not for the Cao family, but for the people of the world? Guan Yu was a little confused by Gao Shun's words.

"One hundred thousand Xianbei Koubian!"

was a simple six words, but it shocked Guan Yu a lot.
