Cao Cao had already fallen asleep, and when he learned that Xun Yu asked to see him late at night, he hurriedly washed his face with cold water, and then came to the study with his clothes on.

On his face, there is still a little bit of sleepiness.

Sent troops from Xudu, first arrived in Yecheng, then rushed to Handan, and came to Xindu...... Cao Cao is nearly fifty years old, and he has long passed his prime, so even if he is physically strong, he can't afford to eat it, and he doesn't seem to be in good spirits.

"Gongda, is there anything wrong with this late hour?"

Xun You hurriedly confessed a crime, and asked in a low voice, "Have you seen the map sent by Youxue and Wen Qian?" ”

Cao Cao yawned, nodded and said, "Gongda said, but do you learn the topographic map of the camp they set up on the north bank of Zhangshui?" ”

"Exactly."

"Any questions?"

Cao Cao looked puzzled, "I've seen that picture, Youxue and Wen Qian's camp design is not bad." ”

"How can I say that it is not bad, I think Youxue and Wenqian will be in great trouble."

"Huh?"

Cao Cao was stunned and suddenly came to his senses.

He immediately stood up and shouted outside the study: "Come on, take a map of Jizhou." ”

"Whoa!"

The person on duty outside the door was Xu Ding, and after a while, he walked in with a map and ordered someone to hang it in the house.

Xun You held a pine light in his hand and walked to the map.

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

Cao Cao hurriedly stepped forward and stared at the map.

Cao Peng and Lejin's camp is located on the south bank of Zhangshui, which is also a narrow part of the river. Upstream of Zhangshui. It's Xiabo County. There are Cao army soldiers and horses stationed. Cao Cao didn't feel anything at first. But after looking at it for a while, a solemn look appeared on his face.

"Gongda means ......"

Xun You smiled bitterly and nodded, "If I were Liu Chuang, I only needed to ...... here."

He pointed to the blue line on the map representing the Hutuo River with his hand, and said softly: "Even if Wen Qian's army of 100,000 people, he will not want to dodge it." ”

Cao Cao's face became more and more ugly.

He groaned for a moment, then suddenly turned and went out. Summoned Xu Ding, "Meng Kang, you immediately send someone to the Zhangshui camp, pass on my order, and ask Youxue and Wen Qian to immediately pull out the camp and retreat twenty miles...... No, forty miles to set up camp, there must be no mistake ......"

"Whoa!"

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

looked at Xu Ding's back. Cao Cao's face did not soften, but became more and more cold.

"Gongda. Is it in time? ”

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

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

Lejin's Zhangshui camp is heavily guarded.

It was late at night, and after inspecting the camp, he returned to the Chinese army's tent.

Cao Peng was sitting on a Taishi chair and was reading a book.

Le Jin sat down and said with a smile: "Youxue, what are you reading?" ”

Cao Peng put the scroll in his hand, "The new book of Mengde compiled by the lord was sent to me before, and I haven't had time to read it yet." ”

Meng De's new book is a military book written by Cao Cao based on Sun Wu's thirteen chapters, plus his experience in marching and fighting over the years. The circulation of this book is not very widespread, except for a few people of the Cao clan, it is not circulated in the outside world. Le Jin has also heard this military book for a long time, but he has no chance to read it. Seeing that Cao Peng was fascinated, he couldn't help but show a look of envy and sighed softly.

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

Just look at Cao Cao giving this new book of Meng De to Cao Peng, you know how much Cao Cao values him.

To be honest, Lejin was a little envious.

But he also knew that he couldn't compare to this kind of thing.

Although Cao Cao also attaches great importance to him, he seems to be some distance behind Cao Peng. It's not that Cao Cao prefers it, it can only be said that in this era, the concept of family and the world is too strong. Cao Peng, who is Cao Cao's nephew...... It is said that Cao Cao intends to accept him as a righteous son, although he is not very old, and his qualifications cannot be compared with Lejin, but in Cao Cao's heart, his status may not be inferior to Lejin.

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

He abruptly closed the book and handed it to Lejin.

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

"This ...... Not good. ”

"Eh, what's wrong. My lord gave it to me, and that was my belongings.

If General Wen Qian likes it, he might as well take it back and copy it again. If it weren't for the fact that this book was given by the lord himself, I would have used it to read it all the time, and it would have been okay to give it to you in the face of the lord's examination......"

Speaking of this, Cao Peng sighed.

"I've heard people say that Liu Chuang has made a kind of machine that can be quickly printed into a book.

It's just this kind of thing, he protects it very well. Although the lord sent many small works to investigate, he could not find out where the thing was hidden. ”

The 'things' that Cao Peng said refer to the movable type printing press invented by Zhuge Ling and Huang Yueying.

The advent of movable type printing has indeed greatly reduced the cost of reading for readers in this era. Liu Chuang intends to vigorously develop the academy, especially after the opening of the Yenching Academy, which requires a large number of books. The appearance of the movable type printing press qì gave him a lot of help.

Cao Cao had also heard of this kind of machine, and even sent someone to investigate.

It's just this kind of technology, Liu Chuang must be strictly protected.

Cao Cao sent a lot of fine works, but he gained nothing, and even lost a lot of fine works in vain.

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

Of course, there is little to be gained.

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

Some students who couldn't endure the bitter cold of western Liaoning, or who were worried that Liu Chuang would suffer retaliation and leave because of the battle of Guandu, regretted it after learning that Liu Chuang was in the north. But if you want to go back, it's unlikely. Many people simply flaunted the banner of students of Nanshan Academy and swaggered around. Not to mention. Many local officials are kind to those who came out of Nanshan Academy. It's quite recognized.

It's just these students. It is impossible for most of them to come into contact with Liu Chuang's core technology.

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

Le Jin said suddenly: "Do you know that the Liu bus that appeared in Shuofang recently?" ”

"You mean, that is the Liu bus that can automatically draw water from the river and water the farmland?"

"Exactly."

Cao Peng showed 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 from the market, could have such a wonderful idea. And how can he attract so many strange people and strange things? He's not much older than me, but how can he convince so many people? ”

After listening to it, he was silent.

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

Of course, as a child of the Cao clan, Cao Peng is among Cao Cao, and it is normal for him to be a little arrogant.

However, how can Liu Chuang convince the public?

Lejin can't say it well.

Is it by virtue of the prestige of the marquis of Laozi? At first, Lejin thought so.

But now, who would say that Liu Chuang is the son of Liu Tao, and people say Liu Tao. It will inevitably be said that the Marquis of Zhongling is the father of Uncle Liu Huang...... Thinking of this, Le Jin shook his head with a wry smile. He was holding the book. stood up and said, "Youxue, you come to be on duty in the second half of the night, and I'll go back and rest first."

I heard that the lord had arrived in Xindu, and said that in a few days, he would come to Wuyi.

In the past two days, you and I have worked harder, and we must not go wrong...... Although we defeated Pang De, Liu Chuang may not be willing to give up. ”

Cao Peng listened and nodded in understanding.

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

And Cao Peng sat in the big tent and took out a copy of the "Spring and Autumn Notes" compiled by Hu Zhao and looked at it.

Outside the tent, there was silence.

From time to time, the sound of fighting was heard, echoing over the camp.

When it was about the end of the day, Cao Peng stretched his waist and walked out of the big tent.

"Childe, do you want to patrol the camp?"

Youhu stepped forward and saluted Cao Peng respectfully.

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

He got on his horse and began to patrol the camp with a group of his own men. In Cao's camp, there was silence, and most of the soldiers of Cao's army fell asleep, and they saw many soldiers patrolling the camp along the way, which also made Cao Peng feel very satisfied. He walked through the camp for almost an hour. At this time, it was almost dawn, and it was pitch black outside the camp, and I couldn't see my fingers, only listening to Zhangshui's whimpering.

Cao Peng took his relatives and rode out of the gate.

They walked along the banks of the Zhangshui River, and a moment later Cao Peng climbed a high post and raised his eyes to look across the Zhangshui River.

But I saw the other side of the river, dark and quiet......

In the past two days, the Han army did not retaliate.

According to the detailed report, Liu Chuang has personally led the army to Anping, and the general will come to Zhangshui in the near future.

Cao Peng has seen Liu Chuang...... At the beginning of the Yecheng Change, Cao Peng went to Yecheng with Jia Xu, and saw with his own eyes how Liu Chuang fought his way out of the encirclement.

He has always been unconvinced, thinking that Liu Chuang is lucky.

Last time in Yecheng, if it weren't for the sudden rebellion of Cen Bi, the captain of the East Gate, I am afraid that Liu Chuang would not have escaped even if he had great ability.

However, escaping is escaping after all, no matter how unconvinced Cao Peng is.

"Did you hear anything?"

Cao Peng had planned to return to the camp, but when he was about to leave the high post, he suddenly reined in his war horse, listened attentively, and asked his relatives after a while.

The relatives showed a look of doubt, you look at me, I look at you.

"Childe, there's no sound!"

"Really?"

Cao Peng turned his horse's head and put his hand on the pergola to look into the distance.

Just now, he seemed to hear something...... When I looked closer, the sound suddenly sounded again.

Boom, boom......

Cao Peng's face changed suddenly, and he turned his head to look at the people around him.

This time, his face also changed, and he obviously heard the strange sound.

Looking along the other bank of Zhangshui, Cao Peng saw that along the course of the Hutuo River, there was a faint bright white dragon roaring towards Zhangshui.

Getting closer, the sound getting louder and louder.

Cao Peng's face turned blue, and he suddenly turned his horse's head and shouted, "Run!" ”

He had already reacted at this time, what a giant dragon, it was clearly the Youzhou army building a dam to store water in the upper reaches of the Hutuo River, preparing to attack Cao Ying.

The roar of the flood behind him grew louder and louder, deafening.

A white water dragon rushed in, cutting off the water in an instant...... The water wave was more than three meters high, and it hit the embankment of the Zhangshui River with a bang, and the rushing flood quickly submerged the embankment, like a mad beast, menacing, and pounced on Cao Ying.
