At the beginning, when Jin Jue sent Liu Shan to Xuzhou to persuade Kong Rong not to enter Xudu, he once asked Liu Shan to warn Liu Bei that among the generals of Mount Tai, they should be attentive to Zang Ba, Wu Dun, and Yin Li, and be more careful with the Sun brothers, because the younger brother Sun Guan is committed to Cao Cao, as for Changba, it can be used, but also be careful of this person repeatedly.

Therefore, Jin Jue suggested that Liu Bei send people to secretly monitor the Sun brothers and Changba's every move.

Unexpectedly, Jin Jue's small suggestion at the beginning allowed Liu Beijun to find out about Cao's army's movements several days in advance, and had already prepared in advance to deal with Cao's army's attack in Pengchengguo, Donghai County and Xiapi Kingdom, the three counties that Liu Bei could fully control.

This time, without Liu Bei's orders, Guan Yu obediently ordered someone to set fire to Peiguo, Lu Guo, and all the fields north of Pengcheng County in Pengcheng County.

In fact, after the experience of the second Battle of Xuzhou, Guan Yu has also learned wisely, and he estimates that Cao's army will attack Xuzhou this year. Therefore, in this year, Guan Yu made two preparations, just waiting for Cao Jun to come!

First, Guan Yu personally led his troops to move all the people who could be found in the northern part of Pengcheng State, the northern part of Peiguo and the southern part of Lu State controlled by Liu Beijun to the south of Pengcheng County and the south of Peiguo, and concentrated the people's strength to build Tuntian in these two areas.

Second, Guan Yu personally led 10,000 soldiers to build three simple lines of defense in Pei County and Xia Qi County.

In fact, this line of defense was just an illusion, and Guan Yu's purpose in building it was just to delay the speed of Cao's army's advance. Guan Yu set fire to those fields, it was not that there were no crops for them, but he actually went against the norm and planted a large number of alfalfa in these fields according to the words of Liu An, who seemed extremely unreliable.

The people of Peng Chengguo will first ask, what is the bearded general doing when he doesn't use good land, doesn't grow food, and grows grass?

Nature is used to raise pigs!

At this time, Guan Yu did not realize that raising pigs can actually play a role in saving food, and he has not mastered the method of castration. This is an untold secret in Jin Jue's army, only Lu Huo and his subordinates know, and Liu An naturally does not know.

However, Guan Yu also did this for a reason. Crops grow in the ground and cannot be harvested until they are ripe, and when the enemy comes, if they hoard too much and cannot hold the city, they will only stay with the enemy, but raising livestock is different.

Whether it is raising sheep or pigs, or raising war horses, these animals can be moved with the army.

Guan Yu cultivated alfalfa on a large scale in the northern part of Pengcheng Kingdom, on the one hand, he could let the Tuntian soldiers raise pigs and sheep with him, and on the other hand, he could raise and breed horses in the territory.

Xuzhou is not the horse breeding land of the Han Dynasty, but relying on the excellent pasture, Guan Yu can raise the war horses he already holds in his hands very well. Even, the green head of alfalfa can be eaten as a vegetable.

Jin Juejun has another place to use alfalfa - beekeeping and nectar collection.

Artificially bred bees, Huaxia does not know when it will rise, but in order to satisfy his appetite, Jin Jue has sent people in Hanzhong County to start the experiment of artificial bee breeding.

After a year of governance of Peng Chengguo, part of Lu and Peiguo, Guan Yu has a new understanding of Jin Jue, this kid, at this time, no matter how arrogant Guan Yu is, he has to admit in his heart that Jin Jue is indeed a genius in the world. Jin Jue's many whimsical ideas helped Guan Yu a lot.

No, when Cao's army had just invaded Peiguo, Guan Yu immediately ordered to burn the alfalfa in the controlled area while ordering the Tuntian soldiers to drive all the livestock in Pei County to Pengcheng County.

At the same time, in the face of the Cao army's attack, Guan Yu adopted the strategy of retreating one after another, neither facing the Cao army head-on, nor fleeing in a hurry.

Of course, the reason why Guan Yu was able to do this was not how strong his ability to train troops was, but that the Xuzhou soldiers he led had always shown great tenacity in the face of Cao's army.

Guan Yu asked them to dig trenches, and the soldiers from Xuzhou dug trenches and worked very hard; Let them take Changge to meet the enemy, the Xuzhou soldiers didn't say a word, picked up the Changge in their hands and fought hard with the Cao soldiers on the opposite side, one by one they seemed to be fearless of death.

In the face of such an enemy, no matter how strong the Cao army's generals were in training their troops, and no matter how elite the soldiers they trained, they would not be able to completely defeat the 8,000 Xuzhou infantry and 1,000 Xuzhou cavalry in Guan Yu's hands.

On this day, in Cao's military camp tent, Cao Cao suddenly received a military report sent back by Xiahou Yuan.

Why is it so hard?

Because, Liu Bei's secret agents planted in Taishan County had already robbed and killed two waves of messengers sent back by Xiahou Yuan to deliver the message in the middle of the road. And the only messenger who was not blocked happened to run into the army of the Sun brothers, and the number of spies planted by Liu Bei in Taishan County was very small after all, so this envoy escaped.

"My lord, what does Miaocai's letter say?" Guo Jia saw that after Cao Cao read the letter, his face changed drastically, and he began to be in a daze, so he hurriedly asked.

"Alas......! See for yourself! When did Changba become so powerful? Cao Cao and Guo Jia's words woke up, he handed the letter to Guo Jia, and finally, he couldn't help but sigh.

Previously, through talking with Guo Jia and Xun Yu, Cao Cao also thought that the Xiahou Yuan he sent was definitely more than enough to deal with Changba.

However, no one thought that Xiahou Yuan, who had a slight advantage in troops, was not able to defeat the small city of Kaiyang City in a battle when Changba was not aware of it.

Guo Jia glanced at it, and handed the letter to Xun Yu on the side, followed by Xun You, Zhong Xuan, and Dong Zhao.

Jia Kui was temporarily appointed by Cao Cao as the Taishou of Chenliu County because the matter of the mission to Yizhou was not done well. Cao Cao didn't disapprove of Jia Kui's ability, but he just didn't want to see him in the army for the time being.

Cao Cao's other great strategist Cheng Yu was left in Dongjun, last time, Dongjun was run by Sima Yi as empty, although Cao Cao made up for it from Chen Jun, but he could no longer bear the pain of Dongjun being emptied again.

and Yingchuan County Taishou was handed over to Cao Cao's younger brother Cao Ren.

After reading it, several strategists all shook their heads, and they all had the same opinion on Changba's judgment. If it weren't for the influence of external forces, there would have been no such deviation at all.
