Cao Cao and Yuan Shao had been fighting each other for months, and the two armies had clashed many times, winning and losing each other. Cao Cao still relied on Guandu's natural danger to defend Guandu, and Yuan Shao used superior forces to encircle Cao Cao, the soldiers on both sides were already very tired, relying on willpower to persevere, any small mistake could affect the situation of the battle!

Xu Du was too guarded in the house, and Xun Yu summoned Lu Rui in the main hall.

"Teacher Xun!"

"Extraordinary? Have a seat! ”

"Thank you, teacher!"

"I don't know if the teacher is here, why is it?"

"Extraordinary, this is a letter sent by the lord not long ago, look at it!"

"Hmm!" After receiving the letter, Lu Rui read the contents, it turned out that Cao Cao and Yuan Shao had been facing each other in Guandu for a long time, and Cao Cao wanted to withdraw his troops to rest and recuperate, and use the terrain of Yanzhou to fight a protracted war with Yuan Shao.

"What is the teacher's advice?"

"Although our army is tired, but the morale is still there, now the two armies are facing each other, fighting is perseverance, Yuan Shao's army is stronger than our army, and its difficulties are more than our army, Yuan Shao has not yet withdrawn, how can our army retreat first?"

"Teacher Takami!"

"Yuan Shao has more difficulties than our army, and there must be more loopholes than our army, as long as he persists for a few months, Yuan Shao's weaknesses are revealed, and our army will definitely be able to defeat Yuan Shao by seizing the fighter!"

"Rui agrees with the teacher's suggestion, so what does the middle father mean?"

"The lord agreed to Yu's suggestion, but the grain and grass in Guandu were insufficient, and now Yu decided to escort the grain and grass to Guandu by Bufan to support the lord, and told the lord that Yu will definitely actively raise grain and grass to support the lord to stick to Guandu." Thanks to Lu Rui's reservoir suggestion, Yanzhou has had a bumper harvest this year. Military rations can be supported until next fall. Such. Cao Jun does not have the dilemma of a shortage of grain and grass.

"Rui Ling!" Lu Rui arched his hand and accepted the task of going to Guandu.

The next day, Lu Rui took the grain transport team to Guandu.

On the outskirts of Xudu, Lu Rui's speed was very slow, because Cao Cao sent a letter a few days ago, and the grain storage was only enough for half a month, and now it is estimated that the grain storage is only enough for ten days. Lu Rui deliberately slowed down the trip, if history had not changed. Then Xu You will serve Cao Cao in seven days, and if history changes, Lu Rui will also arrive in Guandu seven days later to supply Cao Cao with grain and grass.

"Master Hou, why don't we speed up the march? Lord Sikong's side is already tight. Murong Ping saw that Lu Rui's marching speed was much slower than usual, and asked Lu Rui in confusion.

"Our army should be cautious, if Yuan Shao sends people to raid our army, and the grain and grass are lost, how can I explain to Lord Sikong? So our army marches by day. Set up camp at dusk, find out the enemy's situation, and then march. Make sure nothing goes wrong! "I can't tell you, I want to see if history has changed!

"Master Hou is cautious, admire!"

In the dense forest near Tiger Pass, Xu You was analyzing the intelligence of the Cao army that came in, and suddenly a small soldier came in to report.

"Report, my lord, another piece of Cao Jun intelligence has been intercepted!"

"Bring it on!"

"No!"

Xu You read the information and smiled, Meng De, I'm sorry, I want to offer a strategy to defeat Cao Jun to Ben Chu!

"Order, the whole army returns to Guandu and accelerates the march!"

"My lord, there are no people here?"

"No more, no more!"

"No!" Xu You took the information, took the cavalry, and hurriedly marched back to Guandu.

In Guandu, in Yuan Shao's barracks, the letter of the trial was delivered to Yuan Shao, and Yuan Shao was looking at the evidence provided by the trial.

The trial did not say in the letter that the trial had slaughtered Xu You's family, but only that Xu You's family had been disposed of according to the law. Yuan Shao didn't pay attention either, and focused on the evidence provided by the trial.

Xu You and Cao Cao's correspondence is mostly small talk between friends, nothing, of course, it involves the private affairs of some wives and wives, Yuan Shao just glanced at it and threw it aside, after all, there is nothing wrong with these things Xu You and Cao Cao recalled, everyone was young and frivolous.

However, there was a piece of evidence that Yuan Shao did not know, which made Yuan Shao's heart feel guilty. Xu You actually intended to join Cao Cao to support the Marquis of Hefei as the emperor, which Yuan Shao never knew!

Since Xu You joined Yuan Shao, he has always disrespected the Han Emperor and tried to support the new emperor, which coincides with Yuan Shao, so as his friend and with the same political vision as himself, Yuan Shao has always trusted Xu You, but this evidence made Yuan Shao have doubts in his heart.

"Ziyuan? Could it be that you came to serve me because of Cao Cao's honor? ”

"Ziyuan, in your heart, am I not as good as Mengde? Ziyuan, do you have any secrets with Meng De? ”

Thinking of this, Yuan Shao began to feel uneasy, if Xu You and Cao Cao really had a problem, then his current situation would be very dangerous, very dangerous!

"Someone, where did Xu Yu go?" Yuan Shao remembered, it seems that he hasn't seen Xu You for a long time, where did Xu You go?

"Lord Qi, Mr. Xu led his troops to the west, and his movements are unknown."

"What? Xu Yu went to the west! Yuan Shao was stunned for a moment, waved his hand, and let the soldiers retreat.

"Ziyuan? What are you going to do in the west? The raid on Cao's army should also go from the east! Yuan Shao's heart became more and more uneasy.

"Lord, Mr. Xu is back!" Three days later, Xu You finally returned to the Guandu military camp.

"Let him in!" Yuan Shao has been extremely nervous for the past few days, thinking about the relationship between Cao Cao and Xu You, and he can't sleep at night.

"No!"

"Originally, I found a way to defeat Cao Jun!" As soon as Xu Yu entered the military tent, he got carried away and called Yuan Shao's cousin.

"Ziyuan is back?" Yuan Shao's face showed displeasure, this is a military camp, and he actually calls himself a cousin? Whoever is the lord and who is the minister!

"See the lord!" Xu You immediately discovered Yuan Shao's dissatisfaction and immediately changed his tune.

"Why is Ziyuan so flustered and out of proportion?" Yuan Shao suppressed his anger, and then glanced at Xu You.

"Lord, you have found a winning strategy to defeat Cao Jun!"

"The winning strategy? Ziyuan, tell me about your winning strategy! ”

"Lord, his subordinates found that the military rations in Cao's army had been less than three days, and his subordinates led the cavalry to detour through the rear of Cao's army and intercept Cao's army's army transporting grain.

"Cao's army will be defeated? How did Ziyuan know that Cao Cao's military rations were less than three days? Yuan Shao suddenly raised his voice and questioned Xu You.

"My lord, my subordinates intercepted a number of pieces of information about the Cao army near the Tiger Prison Pass, according to the intelligence of the Cao army, the Cao army is short of food, and has urged Xu Du to have food many times, Xu Du has not sent food on time, and his subordinates estimate that Cao Cao's military food is insufficient, and the military food of Yanzhou may be difficult to support Cao Jun, even if it can support Cao Jun, it is not as strong as my Hebei foundation." Xu You said his opinion in one breath.

"Intercepted multiple pieces of Cao Jun intelligence?"

"How can Ziyuan intercept many pieces of information about Cao Jun without being known by Cao Mengde?" Yuan Shao glanced at Xu You, it was weird!

"This?" Xu You was stunned for a moment, Yuan Shao seems to have a lot more problems today, don't trust himself?

"Lord, after many days of observation, my subordinates found that Cao Cao would use three people to send the same information, in order to ensure that the information was smoothly transmitted to the rear, and the subordinates did not kill all Cao Cao's intelligence officers, but only killed one of them, Cao Cao and our army have been holding each other for a long time, and it is estimated that they have not found it yet."

"Shut up! Xu Ziyuan, Cao Mengde is such an careless person? How could you catch the person delivering the information? Our army has been searching for half a year, but we have not yet found Cao Jun's secret agent, and as soon as you came out, you found out? Before Xu You could finish speaking, he was interrupted by Yuan Shao.

"This." Xu You looked at Yuan Shao in surprise, Yuan Shao in front of him became so strange, he reprimanded himself as a stranger, even if someone slandered him, who could be so efficient?

"Hmph, Xu Ziyuan, look what this is!" Yuan Shao threw the bamboo slips that Xu You had communicated with Cao Cao to Xu You.

"Lord, these are my personal letters with Meng De when our army was on good terms with Cao Jun before, my lord, this is just some wind and snow!" Xu You anxiously explained to Yuan Shao that someone in Yecheng must have found these bamboo slips of his own and reported them to Yuan Shao, and Yuan Shao was suspicious!

"Shut up! Come on, drag Xu You out and beat thirty military sticks! ”

"This?" Yuan Shao's personal soldiers heard Yuan Shao's summons and entered the military tent, stunned for a moment, and wanted to torture Xu You? Did Yuan Shao issue the wrong military order?

"Look what! Drag it out and beat it with thirty sticks! ”

"No!"

"Lord, lord, listen to me!"

Yuan Shao waved his hand, Xu You was dragged out, and then he heard Xu You's scream! (To be continued......)
