"Who is Zhu Wu?" Cao Xiu didn't know much about Zhang Yi's subordinates than Xiahou Yuan, and he also knew that several of Zhang Yi's more famous generals, such as the prestigious Di Qing, Shang Shifu and Wei Wentong, as well as Li Jing and Gan Ning, who fought one battle after another. He really doesn't know who this Zhu Wu is, but think about it, it's just a county, and it's not as high as his official position!

Liu Fu said: "Zhu Wu has taken refuge in Zhang Yi very early, but he has never been able to get a good record. However, since Zhang Yi put Zhu Wu in Xia Cai, then he must have something extraordinary. Looking at the generals Zhang Yi placed in the north, Yang Zhi and Hua Rong are all outstanding people, although Wang Jian, Zhu Wu, and Xu Sheng are not famous, but the position of the guard is much more important than Yang Zhi and Hua Rong, and they must have their advantages. ”

Cao Xiu has more soldiers in his hands, and he has enough confidence, he wants to get back on the field, "If you have any ability, you have to fight a game." ”

Liu Fu didn't stop Cao Xiu, Cao Xiu's attack on Shuizhai was Xiahou Yuan's order, and he had to attack anyway, so that he could be confident, maybe the effect would be better.

Cao Xiu surrounded the water of the water village, and then began to build siege equipment to prepare for the attack on the water village.

At this time, Cao Cao also left Xiapi, and he also made some understanding of Zhang Zhao in Xiapi. However, Zhang Zhao's understanding is also limited, Zhang Zhao is not a professional intelligence expert after all. He can only start from some superficial places, and there is not much information to dig up.

Cao Cao had its own intelligence department, and each dynasty had its own intelligence department. However, these intelligence departments are not formal agencies, and it was not until the Ming Dynasty that there was a formal spy agency, Jinyiwei, and then to Dongchang. Like many of the secret agencies that are said in the middle, they are exaggerated, and the secret agencies before the Ming Dynasty were not like secret agencies at all, but more like procuratorial agencies or investigative agencies.

The earliest spies were used to detect the enemy's situation, and there was such an organization since the Western Zhou Dynasty, called Bang Spy. In the Eastern Zhou Dynasty, Hou Zheng was called, the Western Han Dynasty was called the embroidered messenger, and Cao Cao also set up a special agency, called the school affairs. After that, the Northern Wei Dynasty had a marquis, the empress set up an internal guard, the Song Dynasty had an imperial city division, the Ming Dynasty had a guard and three factories (Jinyiwei, East Factory, West Factory, Neihang Factory), and Yongzheng's sticky pole.

Although Cao Cao did not set up a school at this time, he already had this idea. Zhang Yi's subordinates made him feel threatened, and if he didn't set up a reconnaissance agency to reconnoiter Zhang Yi's subordinates, he really didn't know the bottom of his heart!

When Cao Cao's soldiers were in Huaiyin, they were blocked by Huaishui. In the face of the warships cruising on the Huai River, Cao Cao was also a little at a loss. He doesn't have any talent who is good at water warfare! What can I do? Now getting a boat to directly fight a water war with Zhang Yi is equivalent to letting the soldiers die.

This time, Cao Cao brought Cao Hong, Zhang Liao, Xu Huang, Cao Zhen, Zhu Ling and others, and the strategists brought Xun You, Xu You, and Guo Jia.

Xu You has made a lot of contributions since he defected to Cao Cao, and he and Cao Cao used to be friends, so he has never been able to figure out his status. Maybe for Xu You, whether it is Yuan Shao or Cao Cao, they are all his good friends, and I will help you under you, it is for friendship, not a matter of superiority and inferiority. Therefore, when Xu You was under Yuan Shao, he often sat on an equal footing with Yuan Shao.

Yuan Shao was able to tolerate Xu You, mainly in two aspects, one is that Xu You is a celebrity, and he is also a celebrity who has been famous for a long time. As early as more than ten years ago, a year or two after the Yellow Turban Uprising, Xu You wanted to support Wang Fen, the assassin of Jizhou, to detain Emperor Ling, and then support another emperor.

Later, when this matter was revealed, Xu You hid it, and received a lot of help from Yuan Shao during this period. After Emperor Ling died, Yuan Shao arrived in Bohai County, and Xu You naturally went to Yuan Shao's men. It can be said that Xu You is one of Yuan Shao's starting team, so Yuan Shao is still relatively tolerant of him.

On the other hand, Xu You is very powerful, Xu You is a very powerful person, and Yuan Shao has made great efforts to capture Jizhou Xu You. After that, Yuan Shao achieved the foundation of the north, and Xu You also contributed a lot.

So although Xu You was disrespectful to himself, Yuan Shao still endured it. But when he and Cao Cao were in a stalemate, Xu You was still embezzling military funds, which made Yuan Shao unbearable, you can have small shortcomings, but you can't ignore the general situation! Yuan Shao wanted to find Xu You over, scold him, and then punish him for being angry.

But when Xu You heard that Yuan Shao confiscated his family property, he immediately switched to Cao Cao and told Cao Cao about Yuan Shao's grain land, so that Cao Cao could win the fire and the black nest.

As a result, Xu You, who had made great contributions, germinated, and he was not polite to Cao Cao, and the lord did not call him, but called Meng De!

Ancient people's characters are indeed addressed to people, but generally acquaintances, elders or superiors are in charge of the title, juniors and subordinates should not be called, but should be called their relationship titles (such as eldest brother, uncle) or official position. Xu You's words to address Cao Cao by his subordinates are a sign of disrespect for Cao Cao.

As soon as this discussion began, Xu You said: "Why should Meng De worry, now that it is winter, there will be ten and a half days and a half, and there will definitely be ice on the Huaishui. ”

Xu You shouted Cao Cao Mengde, not once or twice. Cao Cao must be unhappy in his heart, but Xu Yu is still useful, and he will keep him for the time being. So Cao Cao pretended to be sad and said: "Ziyuan's words are very true, but I'm worried that Chen Deng and Yu Ban won't be able to wait for more than ten days!" ”

Although Xu You is arrogant, he still has the ability, "Chen Yuanlong is a famous person in Xuzhou, not an ordinary person." Although Yu Wenze's article is not obvious, he is a good general. The two of them are shooting the sun, there are nearly 10,000 elite soldiers, and Zhang Yi's soldiers and horses are less than three times, so there is no need to worry about shooting the sun! ”

Can Cao Cao not know? Of course he knew, but he still wanted to get over as soon as possible. His goal was not to keep Sheyang, but to recapture the other counties of Gwangling County. Guangling is a very important place, if Zhang Yi occupies Guangling, then Cao Cao can only use troops in winter if he wants to attack him. Then in this era, the materials consumed by the soldiers in winter are many times that of spring and autumn, and it takes a long time to prepare for the warmth alone. It is necessary not only to have thick clothes, but also thick bedding, otherwise the non-combat attrition will be too powerful.

The reason why Cao Cao has only arrived in Huaiyin now is that he came over in time, he has to wait for the Huaishui to freeze before he can cross Huaiyin, and he has waited early to come over, and he consumes too much military food. The second is the need to collect cold things, tens of thousands of troops of cold things are enough to prepare for a few months, if it weren't for Cao Cao's frequent battles in winter before, the cold things have piled up, it is impossible to complete the preparation.
