Zhang Zhiyuan soon discovered that they were in a dilemma. Cao Cao was staring at him, so Zhang Zhiyuan did not dare to counterattack the rear camp with all his might. Moreover, there were also Cao's cavalry in the rear camp, so Zhang Zhiyuan could not let go of the long-range troops to raid the rear camp.

However, if the rear battalion was not taken back, Zhang Zhiyuan's front battalion would fall into a state of being attacked on both sides. What's more serious is that the loss of the rear battalion lost a large amount of food and supplies, and the logistical passage of Zhang Zhiyuan was cut off, leaving Zhang Zhiyuan's army facing the possibility of food outage at any time.

After a round of emergency consultations, Zhang Zhiyuan had two plans in front of him. One was to ask Zhao Yun for help. As long as Zhao Yun's cavalry could appear on the Lu'an battlefield, Cao's cavalry would not be able to play a role. Zhang Zhiyuan could easily take back the rear camp and reopen his logistics line.

Another option is to directly take down the rear camp with all its might, completely destroy Li Dian's heavy infantry, and use his own cavalry to fight Cao Cao's cavalry at the same time. The loss of this choice must be huge, but Cao Cao will also suffer huge losses.

After being in a dilemma for a while, Zhang Zhiyuan decided to use the latter plan because he had no way to determine whether Zhao Yun would come and when. If he came too late, maybe Zhang Zhiyuan's food and grass had been exhausted. Instead of placing his hope on others, it would be better to save himself.

After making up his mind to fight, Zhang Yuanzhi immediately dispatched troops. First, the cavalry attacked from the back door, launched a tug-of-war with Cao Cao's cavalry near the camp, and then slowly pushed the infantry out. These infantry were soldiers of the back battalion and would not have an impact on the combat effectiveness of the front battalion.

Infantry uses crossbow arrows to provide firepower support to the cavalry. The cavalry is responsible for protecting the flanks of the infantry and preventing the enemy's cavalry from attacking, so that Cao's troops slowly squeezes the front and rear battalions passages, and then the infantry slowly moves to both sides. Traps and horse-resisting horses are laid around the infantry formation to liberate the cavalry, and then the new infantry regiment rolls forward and pushes the front line forward bit by bit.

Cao Cao was quite helpless when he received a report on the battle situation. He could only use infantry to press up from the front battalion, forcing the enemy to attack the rear battalion with all his strength. However, it is daytime, players can accurately observe the location of Cao's army, and the long-range weapons in the camp immediately exerted their power, making Cao's army hindered their hands and feet, and the attack power was naturally greatly reduced.

On the other hand, Zhang Yuanzhi's infantry established a stable position on the passage more than one mile, and then placed long-range weapons within range. They began to bombard the rear battalion, and Cao Cao was depressed.

Li Dian could only get beaten with his head down, and this situation was obviously not a big deal.

Cao Cao made a quick decision and ordered Li Dian to evacuate the Hou camp and retreat five miles to establish a camp again. Xu Chu cooperated to protect Li Dian to build a camp.

Zhang Zhiyuan got his back camp as he wished. Cao Cao surprisingly did not fight with the players, but retreated in time, but Zhang Yuanzhi immediately obtained information. Li Dian's troops camped five miles away and were still stuck in his logistics line. Of course, Li Dian's logistics line was also stuck by the players, but Cao Cao's cavalry was obviously more powerful than the players' cavalry.

As the distance became larger, Zhang Yuanzhi had no way to use the fortress battle just now. Even if he could use it and forced Li Dian to retreat again, Li Dian might not be able to build a camp again a few miles away. Once his back camp was too far away from the main camp, he would be attacked by Cao Cao at any time, and then there would be a pattern of defeating each one.

The current situation is that Zhang Zhiyuan is unable to attack, and Cao Cao cannot capture Zhang Zhiyuan's camp. However, the time factor that was originally beneficial to Zhang Zhiyuan has now become beneficial to Cao Cao. This is the victory of Cao Cao's tactics. If it is delayed, Zhang Zhiyuan's troops will be defeated in a few days. Then Cao Cao will pick up the spoils and capture the prisoners.

Now, Zhang Zhiyuan had to ask Zhao Yun for help.

....................................................................................................

Zhao Yun was now outside Bo'an City, staring at the hungry people who couldn't see the edge at first sight, and he was also very depressed!

Cao Cao was cruel enough. When the troops evacuated, they drove all the residents out of the city. When Zhao Yun entered the city, he found that there were fire-burning objects everywhere. He was about to send someone to clean up, but Yi Ren who stayed in the city lit the entire city.

Fortunately, Zhao Yun's troops did not enter the city. Zhao Yun bypassed the burning city and saw scattered residents. Then more and more residents returned from the north. It turned out that Cao's army drove them back and ran away with his own food and grass. Zhao Yun was furious and chased after him for a long time, but because the terrain was not easy to walk, he did not catch up and only grabbed a small part of the food and grass.

When he returned to Bo'an City, the fire had not yet been extinguished, and the tens of thousands of people gathered outside the city were hungry. Although Xu Shu tried his best to manage the people separately, there would be no bargaining chips to stabilize the people without food. In this case, the best way is to turn around early and stop caring about these people, so that these people can fend for themselves. At least, this account will still be counted on Cao Cao. Once he takes over and ignores it, the bad account will be Zhao Yun.

Zhao Yun had no choice but to explain the current situation to the people, and then distributed the last little grain to the people, so that the people could eat first, and then immediately set off on the road and approached the Lishan camp in the south. At the same time, Zhao Yun distributed half of the troops to welcome Huang Zu, who was delivering supplies to the south, and took advantage of the speed of the horses to try to transport a batch of grain tomorrow for emergency treatment.

As long as we can survive tomorrow's most difficult period, as we get closer and closer to Lishan Camp, this crisis will be over.

Who knew that after walking for a long time, he received a letter of help from Zhang Zhiyuan. Of course, Xu Shu knew what Zhang Zhiyuan was doing now. But the nearly 50,000 people in front of him are no longer a matter of interests or interests, but a moral responsibility. If these people make mistakes, Zhao Yun and Xu Shu's reputation would be bad, but it would affect Fang Zhiwen's reputation.

However, Zhang Zhiyuan cannot stand by death. If Zhang Zhiyuan is defeated, Sun Jian will naturally not be able to continue. Cao Cao's strength has not been weakened necessary, which is equivalent to a strategic failure. This is something that Xu Shu cannot accept.

"Zilong. What do you think?"

Xu Shu asked with a frown. Zhao Yun looked at Xu Shu's entangled face. Obviously, Xu Shu hoped to rescue Zhang Zhiyuan himself. But the victims in front of him could not give up.

"Yuan Zhi, what is Cao Cao's cavalry power in Lu'an in your information? It's best to even predict the Yiren's."

"Well... Cao Cao's cavalry is 22,000. Cao Cao himself has a light armored cavalry guard with a number of 2,000, and the cavalry troops of the alien are nearly 12,000. This is the number until yesterday. If there had been a battle between the cavalry on both sides this morning, some of them might have been reduced, but the number would be difficult to estimate."

"Cao Cao's guards cannot go to battle and must be kept as reserves. Then, a total of 34,000 cavalry units have an advantage against Zhang Zhiyuan's 30,000 cavalry, but not very big. I think I can only take two thousand guards to go there. Our purpose is to make Zhang Zhiyuan equal with Cao's army in logistics. As long as we ensure that Zhang Zhiyuan can get the minimum supply, then the stalemate will continue on the Lu'an battlefield."

"I originally planned so. My only concern is whether your two thousand people are enough for Zilong?"

"Haha, it would be a bit of a slap in annihilation of the enemy if it is a serious enemy. Moreover, the opponent is also a military general who is almost eighth level, but if it is just to disturb the enemy and protect the logistics, the power of these two thousand people is enough to involve the opponent's 10,000 or 20,000 cavalry. In this way, the logistics level of both sides will be even."

Xu Shu breathed a sigh of relief and said, "It's great. In this way, when I meet with General Huang Zu here, I can bring the remaining cavalry and Zilong's troops together."

"According to the current itinerary, it will take two days to go to Lu'an in about two days. If the weather has not changed, I can just stick around Lu'an for three days. We will solve the problem of food and grass by ourselves. Two thousand people can last for a few days. If it really doesn't work, just go to Cao Cao to grab it."

Xu Shu discussed some details with Zhao Yun and tried to replenish arrows and food for Zhao Yun's troops. Zhao Yun led two thousand guards to move towards the northeast overnight.

With Zhao Yun's reply, Zhang Zhiyuan felt much more at ease. Although Zhao Yun could send not many troops, as long as he could offset the cavalry advantage of Cao's army on the battlefield, Zhang Zhiyuan's logistics could come up. When the logistics came up, Zhang Zhiyuan would have no worries. In this way, time turned to Zhang Zhiyuan's advantage.

In fact, everyone is fighting for a time node of two or three days.

Zhang Zhiyuan's steady and steady action made Cao Cao a little confused, but Cao Cao could not know what Zhao Yun was about to come. The information Cao Cao received was that Zhao Yun was leading a group of hungry and cold people to the south, trying to reach the Lishan camp before starving to death.

Therefore, Cao Cao was cautious about Zhang Zhiyuan's calm approach, for fear that Zhang Zhiyuan would have any conspiracy. However, after a night passed, except for the small-scale cavalry fighting outside the camp, no major war between the two sides, and Li Dian's camp was also very safe. The scouts sent to the south did not find any trace of the Yi Ren Supply Unit.

The next day, the weather was still gloomy, but it didn't snow. Yi Ren's camp was as strict as ever. However, except for the cavalry running in and out from time to time, the infantry did not have the stance to move, but instead strengthened the camp in the camp. Cao Cao was depressed. What exactly did Zhang Zhiyuan want to do? Aren't he afraid of losing food? Or did he still have a lot of food to store? Or did he want to numb himself and then launch a slam at the moment of his relaxation?

Amid Cao Cao's confusion and confusion, one day and one night passed so peacefully. On the morning of three days, Cao Cao, who had just woken up, received an emergency battle report, and then he was so scared that he was completely awake!

This morning, a small supply unit was raided by two thousand enemy cavalry while heading to Li Dian Camp, and all the troops were destroyed. Subsequently, the 2,000-man unit encountered Xu Chu's cavalry, but Xu Chu did not catch up with the enemy, but was restrained by the enemy and caused huge damage. Xu Chu had to withdraw near Li Dian's camp.

According to Li Dian's judgment, the archers on the opposite side may be Zhao Yun and his guards.

The worst situation happened, Zhao Yun is here!
