Cao Cao had already fallen asleep. When he learned that Xun You was asking for a meeting late at night, he quickly washed his face with cold water, then put on his clothes and came to the study.

There is still a bit of sleepiness left on my face.

From Xudu, he first arrived in Yecheng, then rushed to Handan, and arrived in Xindu... Cao Cao is nearly 50 years old and has passed his prime, so after running around the road, even if he is strong, he can't bear it and looks like he is not in good spirits.

"Gongda, is there anything wrong with it so late?"

Xun You hurriedly said a crime and asked in a low voice: "Has the lord seen the map sent by Youxue and Wen Qian?"

Cao Cao yawned and nodded, "What Gongda said, is it that the topographic map of the camp that Youxue and others set up on the north bank of the Zhangshui River?"

“That’s right.”

"Is there any problem?"

Cao Cao showed doubts, "I have seen that picture. Youxue and Wen Qian's camp design are not bad."

"No matter how bad it is, I think Youxue and Wen Qian will be in trouble."

"ah?"

Cao Cao was stunned and woke up immediately.

He immediately stood up and shouted to the outside of the study: "Come on, come and get a map of Jizhou."

"Here!"

Xu Ding, who was on duty outside the door, walked in with a map and ordered people to hang them properly in the house.

Xun You walked to the map holding a pine tree.

"Lord, take a closer look at Wen Qian and Youxue's camp, is it really appropriate?"

Cao Cao hurriedly walked forward and stared at the map to check.

Cao Peng and Lejin's camp is located on the south bank of the Zhang River, which is also a narrow place in the river. The upper reaches of the Zhang River are Xiabo County, and Cao's army is stationed in the army. Cao Cao didn't feel anything at first. But after looking for a while, a solemn expression appeared on his face.

"The meaning of Gongda is..."

Xun You nodded with a wry smile, "If I were Liu Chuang, I just need to be here..."

He pointed to the blue line representing the Hutuo River on the map and said softly: "Even if Wen Qian's army of 100,000 can't escape."

Cao Cao's face became even more ugly.

He pondered for a moment, then suddenly turned around and called Xu Ding, "Meng Kang, immediately send someone to Zhangshui Camp and send me the order. Let You Xue and Wen Qian immediately set up the camp and retreat twenty miles... No. 40 miles to set up camp, no mistakes..."

"Here!"

Xu Ding didn't know what was going on, but Cao Cao ordered it and he took the order without hesitation.

Looking at Xu Ding's back, Cao Cao's face not only did not ease, but instead became colder.

"Is Gongda. Is it too late?"

Xun You was silent for a moment, and only sighed softly, "I hope..."

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The Zhangshui camp in Lejin is strictly guarded.

It was already dark, and after patrolling the camp, he returned to the central army's tent.

Cao Peng sat on a chair of the Grand Master and was reading a book.

Le Jin sat down and smiled and said, "Friends, what book are you reading?"

Cao Peng took the book in his hand like a scroll, "I just wrote the "New Book of Meng De" and sent someone to me before, but I still haven't had time to read it."

Meng De's new book is a military book written by Cao Cao based on the thirteen chapters of Sun Wu and his experience in marching and fighting over the years. This book is not widely circulated, and it is not circulated outside except for a few Cao clans. Le Jin also heard of this military book for a long time, but he was not able to read it. Seeing that Cao Peng was fascinated by his reading, he couldn't help but show a hint of envy and sighed softly.

It seems that Cao Peng is indeed a person Cao Cao wants to focus on cultivating.

Just by looking at Cao Cao’s new book to Cao Peng, you will know how much Cao Cao valued him.

To be honest, Le Jin was a little envious.

But he also knew that he could not compare such things.

Although Cao Cao also valued him very much, he seemed to be a little far behind Cao Peng. It is not that Cao Cao favored him, but that in this era, the concept of family and world was too strong. As the nephew of Cao Cao... it is said that Cao Cao intended to accept him as his adopted son. Although he was not old and his qualifications could not be compared with Le Jin, his status may not be inferior to Le Jin in Cao Cao's heart.

As if he noticed the melancholy in Le Jin's heart, Cao Peng suddenly raised his head.

He suddenly closed the book and handed it to Le Jin.

"General Wen Qian, do you want to take a look?"

"This...is not good."

"Hey, what's wrong? The lord gave it to me, and that's my item.

If General Wen Qian likes it, he might as well take it back and copy it. If it weren't for the gift from the lord himself, I would use it to read it from time to time and deal with the lord's exam, it would be fine to give it to you..."

Speaking of this, Cao Peng sighed.

"I heard that Liu Chuang had a machine that could quickly copy it into a book.

But he protected this kind of thing very well. Although the lord sent many detailed works to inquire, he could not figure out where the thing was hidden."

The "things" Cao Peng mentioned refer to the movable type printing machine invented by Zhuge Ling and Huang Yueying.

The emergence of movable type printing has indeed greatly reduced the study cost of scholars in this era. Liu Chuang intends to vigorously develop academies, especially after the opening of Yanjing Academy, which requires a large number of books. The emergence of movable type printing machines has given him great help.

Cao Cao had also heard of this kind of machine and sent people to inquire.

However, Liu Chuang must strictly protect this technology.

Cao Cao sent many detailed works, but gained nothing, and even lost a lot of them in vain.

Because of this reason, Cao Cao had to postpone the inquiry. However, on the other hand, he began to increase his recruitment of students from Nanshan Academy.

Of course, there is little gain.

Since the reopening of Nanshan Academy in Guzhu City, several batches of students have been replaced.

Some students who could not stand the bitter cold in western Liaoning, or those who were worried that Liu Chuang would be retaliated for revenge because of the Battle of Guandu regretted it after learning that Liu Chuang was in the north of the Frontier. However, it is unlikely that they would want to go back. Many people simply took the banner of students from Nanshan Academy and showed off everywhere. Not to mention, many local officials quite agree with those who came out of Nanshan Academy.

But most of these students cannot get into Liu Chuang's core technology.

Therefore, although Cao Cao recruited a lot, he had little effect.

Le Jin suddenly said: "Do you know that Liu Gongche who appeared in Shuofang recently?"

"You mean, can you automatically draw water from the river and water the farmland?"

“That’s right.”

Cao Peng showed a curiosity on his face and said softly: "How can I not know?

To be honest, I really didn't expect that Liu Chuang, a guy who started from the market, had such wonderful ideas and virtues, and how could he recruit so many strange people and strange things? He is not much older than me, but how could he convince so many people?"

After hearing this, Le Jin was silent.

He really didn't know how to answer Cao Peng's question.

Of course. As a child of the Cao clan, Cao Peng is a little arrogant and arrogant.

However, how could Liu Chuang convince the public?

Le Jin couldn't say it well.

Did it rely on his prestige of Zhonglinghou? Le Jin thought so at the beginning.

But now, who would still say that Liu Chuang is the son of Liu Tao? People say that Liu Tao will definitely say that Zhongling Hou is the father of Uncle Liu... Thinking of this, Le Jin shook his head with a wry smile. He held the book and stood up and said, "Friends, come on duty in the second half of the night, I will go back and rest first.

I heard that the lord had arrived in Xindu. It was said that in a few days, the troops would come to Wuyi.

In the past two days, you and I will work harder, so we must not make any mistakes... Although we defeated Pang De, Liu Chuang may not be willing to give up."

After hearing this, Cao Peng nodded to show his understanding.

Le Jin then left the big tent and returned to his military tent to rest.

Cao Peng sat in the big tent and took out another "Spring and Autumn Annotations" compiled by Hu Zhao and read it.

Outside the big tent, there was silence.

From time to time, there were sounds of deception, echoing over the camp.

It was almost Yin hour, Cao Peng stretched out and walked out of the tent.

"Young Master, do you want to patrol the camp?"

An entourage stepped forward and saluted Cao Peng respectfully.

Cao Peng nodded, and the entourage immediately went to the stable to come to his mount.

He turned over the horse and began patrolling the camp with a team. There was silence in Cao's camp. Most of the Cao army soldiers fell asleep. They saw many soldiers patrolling the camp along the way, which made Cao Peng feel very satisfied. He inspected the camp and took almost an hour. At this time, it was almost dawn, and it was pitch black outside the camp, so he could not see his five fingers, and only heard the Zhangshui sobbing.

Cao Peng took his followers and rode his horse out of the gate.

They walked along the bank of the Zhangshui River. After a while, Cao Peng climbed up a high hill and looked up at the other side of the Zhangshui River.

But I saw that the other side of the river was pitch black and quiet...
