Not long after Liu Bei reluctantly sent Kong Rong's family away, the ten envoys sent by Jin Jue all arrived safely in Xiapi.

It's not that Cao Cao's army is not well guarded in its territory, first, no one in Cao Cao's army thought that the attack plan they formulated would be leaked in advance, and second, most of the people selected by Liu Shan were the Yellow Turban Army in Yanzhou, Qingzhou, they were originally locals, and they were local snakes, so they could easily avoid local scrutiny.

Ten people and ten letters, but Jin Jue asked people to transcribe one of the original letters in the other nine letters, only the leader designated by Liu Shan, this person was one of the hundred Xuzhou soldiers, he was not only Jin Jue's die-hard loyalist, but also had a blood feud with Cao Cao, so Jin Jue was so relieved to hand over his handwritten letter to him.

Once this person was intercepted by Cao Cao's army halfway, he would definitely destroy the letter before the matter was revealed.

Jin Jue had to be so careful, and in ancient China, he would also use secret methods to transmit military reports. For example, according to legend, it is said that Jiang Ziya wrote "Yin Fu". But he and Liu Beijun did not have a password agreed upon in advance, once the news walked, he would help Cao Caojun if he had a plan, so he could only use this stupid method to send the letter.

Fortunately, all the letters were delivered, and all ten people were alive, and this time, Jin Jue also brought a code book over.

This book is a very common book in the Han Dynasty "Book of Songs", but this Book of Poetry is only two original code books in this world, because he is a Book of Poetry copied by Jin Jue himself, and the number of words written on each page is completely different from the Book of Poetry circulating in the market in the Han Dynasty.

And the principle of superstition was basically transmitted by the two armies, and Jin Jue was only recorded in that handwritten letter.

Liu Bei personally met with the Xuzhou soldier and asked them all to take them down to rest.

"Sure enough! Zijing, Yuan Zhi, both of you guessed correctly, Cao Cao is going to do something to us, and besides, just before this year's summer harvest. That kid got the news from Sima Yi. Check it out! After Liu Bei read the content of the first page of the letter, he said with a calm expression, and after speaking, he handed the page of the letter to the attendant beside him and asked him to pass it on to the person next to him.

Liu Bei was obviously not too surprised, because Lu Su and Xu Shu had also been sending people to secretly observe Cao Cao's every move, and they sensed from the other party's clues that Cao Cao was likely to take Xuzhou first. Even if it were them, they would choose it this way.

There are a lot of words written on the first page of the letter, but the content of the letter is not very much, and it is generally about when Cao Cao will send troops.

The key lies on the second and third pages of the letter.

Page II

"Xuande Gong, do the following three things quickly.

The first piece is a clear wall.

The area under the jurisdiction of General Guan Yu was cleared of the wall.

Specific measures include:

First of all, from the day of receiving this letter, you can send people from north to south, regardless of whether they are ripe or not, to harvest the crops in the cultivated land as soon as possible, even if they can only feed the pigs, and resolutely not leave a grain of grain for the soldiers of the Cao army, and resolutely not leave a single grass for the war horses of the Cao army.

Secondly, immediately send competent officials to organize the old and young women and children in Pengcheng to move to Xiapicheng as soon as possible, so that the soldiers in front do not have any worries.

In the end, let General Guan Yu shrink the strength of each county, concentrate the troops of the whole county in Pengchengguo, but could not hide in the city to defend, let General Guan Yu choose the general to defend the city, and he himself led his troops to fight with the enemy outside the city.

If Cao Jun chooses to fight to the death with General Guan Yu under Pengcheng City, then fight to the death.

If the Cao army chooses to disperse and leave, ignore General Guan Yu, and directly enter the army to attack Xiapi, then General Guan Yu will not have to care about them, but let General Guan Yu choose the elite soldiers, choose his own time, and attack Yanzhou in the north, without caring about the war in Xiapi.

Second, beware of Tarzan thieves.

General Chen Zhi led his troops into Donghai County, and no matter what happened to Xiapi, he must stick to it and strictly guard the county boundary until all the autumn grain is collected in the city.

If the battle between Xuande Gong and Cao Jun goes smoothly or holds each other, the Taishan thief will not move, Xuande Gong can buy Changba with a beautiful woman, this person has a capricious personality, but because he likes beautiful women, therefore, he will not surrender to Cao Cao.

Third, Xuande Gong can order Mr. Zijing to personally command the troops at the junction of Xiapi and Pengcheng, deep ditches and high bases, do not care about casualties, and tell the soldiers in Xuzhou that in this battle, Xuande Gong will definitely fight to the death with them to the end.

If this battle can be held out until before and after the autumn harvest, Cao's army will inevitably withdraw on its own.

In addition, it is enough to let Chen Yuanlong and General Zilong beware of Yuan Shu, who is likely to be emperor after Cao Cao sends troops.

Attached is a sketch of harvesting grain and grass tools, Jue's personal production of the "Golden Fu" and usage, in the future, if Xuande Gong wants to contact Jue, you can use this method. ”

After Liu Bei read the content of the letter on the second page, he couldn't help but gasp, how ruthless!

This kid didn't know what kind of heart An had gained, so he actually asked Cao Cao and me to fight to the end in this battle at the expense of casualties. However, on what basis did he conclude that Cao Cao would definitely withdraw his troops immediately around the autumn harvest?

You must know that before the summer harvest and after the autumn harvest, there were only two months in this period, Liu Bei did not believe that Cao Cao only attacked for two months, and if he was not able to win a complete victory, he would choose to retreat.

After reading it, Liu Bei passed the page of the letter to Lu Su again, and after the people present read it one after another, Liu Bei asked, "How?" Zijing, Yuanzhi, Shuzhi, do you think it is feasible for that kid to write these three things in the letter? Lone had two questions, first, how could he conclude that Cao Cao would retire around the autumn harvest;

Second, if Yuan Shu chooses to send troops to attack Xuzhou at this time, our army will encounter the dilemma of being attacked by the enemy on the back of the abdomen. Will Yuanlong and Zilong be able to hold off Yuan Shu's army? ”

Lu Su was not good at scheming, so he did not choose to answer Liu Bei's question at the first time, but closed his eyes and pondered.

Xu Shu was young and quick-witted, and he immediately replied: "Feasible!" The first question, Lord, according to my guess, either Lu Bu himself wants to sneak attack Yanzhou from the flank again, or that kid said that Lu Bu sent troops to help the Lord relieve your pressure.

Second, Yuan Long and Zilong will definitely be able to resist Yuan Shu's army. Lord, although Yuan Shu has recently recovered a certain amount of military strength, it is all the nearby Yellow Turban Army, thieves and other stragglers, and their combat power can be imagined. Therefore, you don't have to worry so much. But ......,"

Having said this, Xu Shu subconsciously glanced at Liu Bei and Zhang Fei successively.
