Cao Cao said happily: God help me, if there is a south wind, we only need to set fire to the south, and the fire will borrow the wind, and it will be able to burn the black nest and the armor will not exist. Hahahaha!

As for Zhang Jie's camp, Zhang Jie has always been worried about the problem of the black nest, so he sent Hao Zhao, a well-guarded general, to guard the black nest, and Zhang Jie transferred another 10,000 horses to him. plus 5,000 people from Hao Zhao's headquarters. There were fifteen thousand people in total. If Cao Cao sent someone to attack and burn grain, it would be very difficult to succeed.

Jia Xu, who has always been a little talker, said: Lord, if nothing else, the old man has already guessed Cao Cao's plan.

Oh? Wen He said what Cao Cao's idea was? Zhang Jie said.

Jia Xu said: The two armies are fighting, and if you want to defeat the strong with the weak, you have no other way than to win by surprise. The terrain of Guandu is not suitable for water and fire attacks. But if you want to win, you can only cut off the enemy's food and grass.

Our grain and grass are in the black nest, and we can hide it from Yuan Shao and Cao Cao for a while, but it is impossible to hide it for too long. Cao Jun will definitely inform Cao Cao.

Yuan Cao learned that our army's grain and grass could not let go of such a chance to win by surprise? The old man expected that Cao Cao would send troops to attack Wuchao and burn the grain and grass.

Yang Hongdao: Since we know that the enemy army is going to burn the grain and grass, why don't we just plan to eat this enemy who set fire?

Tian Fengdao: If Cao Cao plans to sneak attack the Black Nest, he can only secretly take advantage of the night to take the small road and bypass the official ferry to the Black Nest, and there should not be too many people.

Maybe a few thousand. The maximum will not exceed ten thousand. Because there are too many people, it is easy to be discovered by our army. If we set up an ambush in the black nest, we will definitely be able to eat his 10,000 horses.

Everyone saw that Tian Feng's analysis was correct. They all nodded in approval.

Ju Yidao: My lord, the last general will personally lead the troops to set up an ambush in Wuchao, no matter how many people Cao Cao comes, we will not let any of them escape. It's just that I don't know when Cao Cao will come to sneak attack?

Frustrated teaching: One night watching the sky, three days later there was a southwest wind. If there are people in Cao Jun who know how to read the sky, they should also know that the southwest wind will blow in three days. In this way, Cao Cao is most likely to come to attack three days later, because the south wind is together, and the fire of the black nest will be easier to succeed.

Zhang Jie just wanted to open his mouth and promised to let Ju Yi go to set up an ambush.

But Jia Xu smiled and said: It's better not to set up an ambush, and the lord had better remove some of General Hao's men and horses. Let Cao Cao burn the black nest.

What! Ju Yidao: Wenhe Military Master, you won't be old and confused, right? Knowing that Cao Cao came to burn grain and grass, and asked him to burn it, can you think of it?

Zhang Jie knew that Jia Xuken would not give up the black nest for no reason, so he must have some plan.

Dao: Ju Yi must not be rude, Wen He must have another good plan.

Jia Xu said: The old man has some ideas. I just haven't thought about it yet. Do you want to accompany me for a walk outside the camp? Maybe you can come up with something!

Zhang Jie understood that this was Jia Xu's desire to keep it secret and did not intend to tell it to others. Maybe it's some kind of poisonous plan, it's hard to tell everyone.

Zhang Jie said: Good! Go down and rest. I accompanied Wen He for a walk. Promise!

Jia Xu, Zhang Jie, the two of them walked in front, a few meters behind him, Dian Wei and Zhou Cang followed to protect.

Zhang Jie said: Wen He has any plan to say! There are no outsiders here.

Jia Xu said: If the lord knows that Cao Cao is burning the black nest. What does the main guild do in general?

Zhang Jie thought for a while: Jie will send people to rescue Wuchao on the one hand, and on the other hand, send people to storm Cao Cao's camp. (That's what Yuan Shao did in history)

Jia Xu said: Cao Cao just sent a small force to attack Wuchao, and the large army will still stick to the camp, what will happen if the lord can't break through it for a while?

Zhang Jie said: If the grain and grass of Wuchao are gone, and the camp cannot be breached, the army's morale will definitely be moved, and there is only one way to withdraw the troops.

Jia Xu said: What if Cao Cao sent troops to chase and kill at this time?

Zhang Jie said: Then the only way to arrange is to arrange for a soldier to be broken, and the rest of the people will retreat quickly.

Jia Xu said: For example, Cao Cao sent people to chase and kill continuously in the middle. and set up an ambush on the road. At that time, the soldiers who withdrew fled for their lives, like frightened birds. I'm afraid that the whole army will be wiped out!

Zhang Jie was also shocked, Yuan Shao was defeated like this in history, and in the end, Yuan Shao fled back to Hebei with only a few hundred people, and the army was almost wiped out. I didn't expect Jia Xu to guess it.

Zhang Jie felt that he seemed to understand Jia Xu's plan. Dao: Wenhe gave up the black nest to Cao Cao to burn, did he want to attract Cao Cao to attack?

Jia Xu said: Whether Cao Cao will attack or not depends on the situation. If he found that the lord had retreated in an orderly manner, he might not have pursued.

But if Cao Cao thought that he could defeat the lord's army in one battle, he would definitely order a pursuit. At that time, the lord only needs an ambush to kill. It will definitely catch Yuan Shao and Cao Cao off guard. Eliminate Yuan Cao's main force in one fell swoop.

However, whether you can eliminate Yuan Cao's main force or capture Guandu depends on Guo Jia and Xun You's ability. The old man wanted to meet these two.

Zhang Jie said: But it's a pity that the Wuchao grain and grass are burned. The bait for this fishing is too big!

Jia Xu said: In fact, you can dig holes and bury grain bags in the ground and cover them with soil. Then the fire will not burn. Just leave a small part of the grain for Cao Cao to burn. However, forage cannot be buried in the ground. Cao Cao must be burned down, otherwise Cao Cao will be suspicious.

Zhang Jie said: You can also give each soldier two days' rations in advance. In this way, there will be no panic caused by a sudden food shortage.

No, if the soldiers were given food, Cao Jun would pass the news to Cao Cao. At that time, Cao Cao may guess that it was a trick to lure the enemy and not pursue it. That's not pretty.

Zhang Jie nodded. Dao: Jie knows. It seems that if you want to fish Cao Cao's main force, you have to lay heavy bait!

Zhang Jie returned to the camp tent to find Yang Hong, and said: Zhong Ming, you go to the black nest immediately, tell Hao Zhao to let him immediately put the grain in a sack, dig a hole and bury it on the spot. Cover with more soil. Let the fire not burn. But don't bury the forage and let Cao Cao burn it.

Yang Hongdao: What does this mean, my lord?

Zhang Jie said: Cao Cao will only go out of the camp to pursue when he burns the grain and grass of our army and sees our army retreating. Then let's have another ambush on all sides. Hehe!

Clever! Jia Wen and this plan are clever, but it's a pity to let Cao Cao burn so much grain and grass. Yang Hongdao.

Hehe, I can't bear to let the child trap the wolf. So I asked you to go and explain the situation to Hao Zhao. Let him bury the grain. But don't show your feet. And let him resist desperately when Cao's army burned the black nest, and not show flaws. But it is necessary to let Cao Cao burn the black nest successfully. You have to master this degree. Do you understand? Remember that the grain must be buried well if it is actually burned. Then we're really going to have to withdraw.

Hiroshi understood, and I'll go right away.

Zhong Ming, you have stayed in Wuchao to assist Bo Dao for the past few days. Tell Hao Zhao to fake the show. When burying grain, you must find henchmen and soldiers, do it secretly, and don't leak the news. Be careful with confidentiality. Prevent Cao Jun from being meticulous in the army.

Promise!

Yuanfu, you arrange a few brothers to accompany Zhong Ming to the black nest and protect Zhong Ming.

Promise!
