At the same time as Cao Jun and Yuan Shaojun were fiercely confronting, Liu Yu and Zhao Yun were watching the battle at a high place next to the two camps.

The battle of Guandu was huge in scale, and who won and who lost had a far-reaching impact, of course Liu Yu could not miss it, so as early as the beginning of the battle of Guandu, Liu Yu and Zhao Yun secretly went east with five hundred flying dragon horses.

Zhao Yun asked Liu Yu: "According to the eldest brother, how long will the battle between Cao Cao and Yuan Shao last?" ”

Liu Yu thought about it, and now that both sides have begun to attack each other's grain and grass, presumably Cao Cao will soon realize that he will attack Wuchao and burn the huge amount of grain and grass that Yuan Shao has hoarded in Wuchao, and really cut off Yuan Shaojun's supply of grain and grass.

He said: "I guess we should be able to decide the winner within a month." ”

At this moment, a soldier came to the front.

Liu Yu asked, "Did the words pass on to Yun Chang?" ”

The soldier replied: "Back to the lord, General Guan knows, he replied to the lord, and he must find an opportunity to behead Zhang He and Gao Ran's head to the lord." ”

Liu Yu nodded, Hebei Siting Zhu, Yan Liang and Wen Chou are dead, Zhang He and Gao Ran don't want to let go, he doesn't want to leave any of them to Cao Cao, of course, whether he can kill the Siting Pillar depends on the will of God.

In Cao's military camp, Guan Yu was frowning and thinking.

Guan Yu sighed: "It's a pity that I beheaded Yan Liang and Wen Chou, and I have scared Zhang He and Gao Ran, even with Xiahou Yuan and others, they are only limited in battle, and they will not be equal to the winner or loser, if I make a move, they will not dare to fight, and it is not easy to kill the two of them." ”

Although it is not easy, Guan Yu is also confident, even if he doesn't have the opportunity to kill Zhang He and Gao Ran now, when the final battle comes, in the chaos of the army, he can still find an opportunity to kill Zhang He and Gao Ran, and live up to the expectations of his eldest brother.

During the confrontation between Cao Jun and Yuan Shaojun, Guan Yu did not attack, he only waited for the final decisive battle, and if he did not make a move, he would at least kill one of Zhang He and Gao Lan.

……

Liu Yu didn't know the specific details of the burning of the black nest, but he only knew that Xu Yu seemed to be the key.

It is said that Yuan Shao's army has to cross the Yellow River to transport grain, although it is easier for Cao Jun to detect and attack the grain transport soldiers to rob grain and grass, but Yuan Shaojun has an absolute advantage in numbers after all, Yuan Shaojun sent more military horses to escort, and the probability of being robbed and burned by Cao Jun is limited, in general, Yuan Shaojun's grain and grass supply can barely be supported.

In addition, after more than two months of confrontation and continuous small battles, the Cao army was consumed nearly 40,000 soldiers, and now there are less than 140,000 soldiers left, while although Yuan Shaojun has consumed more than 50,000 soldiers before and after, but now there are more than 340,000 left, which is already two and a half times the size of Cao's army.

Yuan Shao is no longer afraid of a long-term confrontation with Cao Cao, because he is far more optimistic than Cao Cao at this moment, and he is confident that Cao Cao will definitely not be able to support him, and the final victory will belong to him.

Cao Cao is facing more and more pressure, he is becoming more and more urgent, if the confrontation continues, if there is no change, he must be the one who loses in the end.

Cao Cao withstood tremendous pressure and waited for change, and Yuan Shaojun did have a variable that was enough to turn the situation around, that is, Xu You.

It is said that since Tian Feng was imprisoned by Yuan Shao to be beheaded, Xu You and Juan Pei have become the most powerful strategists around Yuan Shao, and both of them are extremely proud. Especially in the trial matching, Yuan Shao and Cao Cao have been facing each other for two months, whether it is archery in the soil mountain, digging tunnels, etc., many strategies come from the mouth of the trial, and Xu You often has schemes, but every time he is refuted by the trial, Yuan Shao uses more strategies than Xu You, which makes Xu You's heart very unbalanced.

Taking advantage of the huge amount of grain and grass consumed by the army every day, and the grain and grass need to be transported across the Yellow River, it is often ambushed by the Cao army, and the pressure on Hebei's grain supply is not small. ”

Yuan Shao trusted the trial very much at this moment, Xu You said this, Yuan Shao also realized that Hebei's grain supply was very important, so he listened to Xu You's suggestion and ordered the trial to return to Jizhou to supervise the grain and grass.

The judge left Yuan Shao's place with a gloomy face and returned to his residence, and then he scolded angrily: "Xu Yu thief, I swear to you that I will not stand on the other side!" ”

The judge thought that Xu You was jealous of Yuan Shao's trust in him, so he carried out this plan to draw his salary from the bottom of the kettle and transferred him away from Yuan Shao's side, so that Xu You could do whatever he wanted.

No matter what, the trial could not disobey Yuan Shao's order, and he returned to Jizhou with unwillingness and annoyance.

The trial didn't supervise much of the grain and grass, and only searched for Xu Yu's 'incriminating evidence'!

He once joined forces with Xu You to suppress Tian Feng, frustrated, and he knew too well who Xu You was, and he knew that Xu You was definitely not clean.

In this investigation, sure enough, Xu You had received bribes from the people many times, and his sons and nephews even used Xu You's name to enrich their own pockets when taxing grain.

The trial was overjoyed, and without saying a word, he ordered Xu You's son and nephew to be arrested and imprisoned, and informed Yuan Shao of the matter.

The action of the trial in Jizhou City was not small, and it was learned by Cao Cao's spies stationed in Jizhou, who informed Cao Cao of the trial first.

"God help me!" Cao Cao laughed when he heard this.

Cheng Yu said: "My lord, there were Xu You, trial and other joint attacks and deception of Tian Feng and frustration, causing Tian Feng to be imprisoned, and frustration can not be trusted, and now Xu You and trial match are attacking and defrauding, I heard that Xu You was a friend of the lord many years ago, so he can take the opportunity to separate Xu You and Yuan Shao, so that Xu You rebelled from Yuan Shao. ”

Cao Cao nodded, and then used Cheng Yu's strategy to try to separate Xu Yu and Yuan Shao.

On this day, there was a letter from Cao Ying to Xudu, and as soon as he left Cao Ying, he was discovered and captured by Yuan Shaojun's soldiers. The soldier sent the letter to the strategist Xu You.

When Xu You saw this letter, he was overjoyed: "The opportunity to break Cao Cao has come!" ”

Almost at the same time, the matter told by the trial from Jizhou and the fact that Xu You was Cao Cao's old acquaintance reached Yuan Shao's ears first, and at this time, Xu You came to see Yuan Shao.

"Lord, Cao Cao is short of food, and Xu Du is empty, you can divide an army into a starry night surprise attack on Xu Du, then Xu Du can be broken, and Cao Cao can be captured!" Xu You was very excited, but he didn't notice Yuan Shao's gloomy face.

Yuan Shao didn't listen to Xu You's plan at all, not to mention that he and Cao Cao grew up since childhood, and knew that Cao Cao was scheming, and thought that this was Cao Cao's plan to lure the enemy and divide the troops, not to mention that the news from Jizhou made him very angry, he was in front of Cao Cao, there was a shortage of food and grass, and Xu You's nephew actually relied on Xu You's name to evade taxes and grain and fill his own pockets, plus he learned that Xu You was Cao Cao's old acquaintance, which made Yuan Shao unable to trust Xu You.

Yuan Shao threw the letter from Jizhou in his hand to Xu You, snorted coldly, and angrily reprimanded Xu You: "You are a man with bad conduct, what kind of face do you have to offer in front of me!" You have an old relationship with Cao Cao, could it be that you accept Cao Cao's property, be a spy for Cao Cao, and lure me to divide my troops, so that Cao Cao can defeat me? ”

At present, Yuan Shao and Cao Cao have confronted each other, and they have gained the upper hand, as long as it drags on for another month, Cao Cao will collapse without a fight. At such a time, Yuan Shao only needs to stabilize himself to win, how can he listen to any strategy and risk dividing his troops to attack Xudu?

Xu You was stunned, he came on the spot, but he was suddenly scolded by Yuan Shao like this, he didn't know what the reason was.

After reading the letter sent by the trial from Jizhou, Xu You was shocked, and he hurriedly said: "My lord, this is the trial and match to harm me!" ”

How could Yuan Shao believe Xu You, he sneered: "Don't talk nonsense again, today you should have beheaded you, and seeing that there is still some credit in the past, I will temporarily send your head to the item, and don't get out of the tent quickly!" ”

Xu You was kicked out of the tent in a daze, it can be said that he came on a whims but almost lost his head, and there is nothing more aggrieved than this. The more Xu You thought about it, the more uncomfortable he became, the more angry he became, he gritted his teeth and said: "Yuan Shao will be defeated by Cao Cao if he doesn't accept his advice, why don't I go to Cao Cao?" ”

The more he thought about it, the more Xu You felt that it was feasible, Yuan Shao no longer trusted him, even if Yuan Shao could defeat Cao Cao, he would definitely not use him anymore and would only believe in his trial.

"If I vote for Cao Cao, one plan can make Cao Cao defeat Yuan Shao, how can Cao Cao not value me?"

After thinking about it, Xu You took advantage of the night to leave Yuan Shao's military camp and went straight to Cao Jun's camp.

In the Cao camp, Cao Cao had just undressed and fallen asleep, when he heard Xu You coming, he was pleasantly surprised, and he didn't even have time to put on his shoes, so he went out barefoot to greet him, and when he saw Xu You from afar, he smiled and beckoned: "Ziyuan, I haven't seen you for many years, I miss Ziyuan very much." ”

Cao Cao excitedly and enthusiastically held Xu You's hand, it was really like an old friend meeting each other, and Xu You's heart was warm, you see that Cao Cao really attaches more importance to him than Yuan Shao.
