You must know that Cao Cao left an army of about 50,000 of the Xiahou brothers in Donghai County, and the army led by himself was only about 70,000 or 80,000.

And sent his eldest son Cao Ang, half of his troops, to Chenliu County to besiege Huaxiong, and divided an army of 35,000 to 40,000.

In other words, Cao Cao's army left in Henan Yin was less than 40,000 troops!

Among them, there were 12,000 to 14,000 troops, which were led by Zhang Yan.

Zhang Yan led his troops to rebel against Cao Cao, and Cao Cao's army was only about 25,000 people left!

When was the army around Cao Cao so few?

It's a must-have!

What's more, Cao Cao also suffered a head wind attack after losing his son and fell into a coma.

In addition, there was a difference of opinion between the leading generals and the strategists.

It's a once-in-a-lifetime opportunity!

Zhang Yan led Cao Cao's army of one-third of Yin's army left in Henan, and on the day of the rebellion, he inflicted heavy losses on Cao's army.

It's a pity that the army around Cao Cao is an elite division, and with the super-first-class generals and super-first-class strategists quickly unifying their opinions, they were hit hard at the beginning, and then they stood firm.

After Cao's army gained a foothold, Zhang Yan knew that his army alone would not be able to defeat Cao's army head-on, so he changed to a delaying tactic to wait for Lu Su's army to come and encircle.

As soon as Zhang Yan changed his tactics, Cao Jun knew Zhang Yan's intentions, after all, Lu Su's army was nearby, and even second-rate generals could guess the result.

Therefore, Xu Chu, Yu Ban and other generals, with a small number of soldiers, Xun You and other strategists, divided into ten routes, with the unconscious Cao Cao, quickly fled the battlefield.

When Lu Su led the army to arrive, Xu Chu, Yu Ban and other super-first-class generals withdrew from the battlefield with less than 100 broken soldiers.

Lu Su led his troops in pursuit for a while, and after finding that Cao Cao's soldiers had fled the battlefield in ten ways, he stopped the pursuit.

After all, the chance of chasing alone is too small, not to mention that there are ten roads on the surface, and there may be a few more roads in the dark, but they fled with Cao Cao himself.

If you follow the division of troops to pursue, it is easy to be gathered by Cao's army and broken by each one.

So Lu Su finally chose to stop the pursuit.

In the end, Lu Su pleaded guilty to Zhao Feng.

If it weren't for Lu Su leading his troops late, Cao Jun could have been surrounded, so that Cao Cao might have been solved directly.

This kind of thing, how could Zhao Feng be blamed.

Judging from the content of the document, Zhao Feng knew that Zhang Yan must not have sent someone in advance to tell Lu Su about the plan to rebel against Cao Cao.

Otherwise, there will be no situation where Lu Su is late!

Instead, Lu Su led his troops, and while attacking Cao's army, Zhang Yan launched a rebellion and defeated Cao's army in one fell swoop.

If you are lucky, you may be able to capture Cao Cao, Xu Chu, Yu Ban, Xun You and others.

Of course, Zhang Yan can't be blamed for the fact that this situation didn't happen.

After all, Cao Cao passed out because of the head wind, and the Cao army camp must be loose on the outside and tight on the inside, and Zhang Yan had no chance at all to send someone to inform Lu Su.

Otherwise, once the matter is exposed, maybe Zhang Yan will be booby-trapped directly!

Zhao Feng learned about the war on Yin's side in Henan, and he also knew why the two brothers, Xiahoudun and Xiahouyuan, couldn't hold out.

Even if Zhao Feng asked Zhang He and Wen Chou to lead troops to test Xiahoudun in Lanling and Tanxian County, Xiahoudun didn't say anything.

This was naturally Cao Cao's strict order, prohibiting Xiahoudun and Xiahouyuan from sending troops to fight Zhao Feng.

Otherwise, once Zhao Feng catches the opportunity, maybe Donghai County, Xiapi County, and Guangling County will all be occupied by Zhao Feng.

Once Donghai County, Xiapi County, and Guangling County were occupied by Zhao Feng, then Zhao Feng would border Yuan Shu.

If you want to attack Zhao Feng or Yuan Shu in the future, you can only consider the comprehensive problems of both sides.

Even, even several counties and countries in the east of Yanzhou will be affected!

Zhao Feng finished reading the paperwork, pondered for a long time, and looked at the sentry horse: "Go back and let Tian Feng prepare a few military orders." ”

"First, let Xu Huang put down his siege tasks, even if there is only the last county town left in Dongjun, he must put it down for the time being."

"Let him lead his troops into Chenliu County and make a momentum to attack Chenliu County."

"Its main purpose is to pick up Huaxiong's troops to leave Chenliu County."

"Second, Cao Cao suffered a big loss this time, and I'm afraid that he won't be able to deal with us in a short time."

"Canonize Zhang Yan as the captain of the department, and the head of the department is under the captain's department."

"Ling Lu Su cooperated with Zhang Yan and quickly took Henan Yin!"

Si Li's school captain, although the name of the position is school captain, is actually the same as the position of the assassin, the official responsible for supervising the land of a state.

It's just that the division is in charge of the prefectures, so it is different from the assassination history of other states in name and power.

After all, the Son of Heaven, the Three Princes, and the Nine Qings, their status and rights are all greater than those of Si Li's lieutenant.

Therefore, the captain of the division, in the department of the captain of the division, is not as powerful as other assassins in other states.

The sentry knight bowed his hand to Zhao Feng: "No! ”

After speaking, he turned around and withdrew from the Chinese army's big tent.

The reason why Zhao Feng canonized Zhang Yan as the lieutenant of Sili was because Zhang Yan had indeed made great contributions.

The second is that the authority of the lieutenant is only the same as that of the assassin, which is the duty of supervision.

Because Luoyang currently does not have the Son of Heaven, Sangong, and Jiuqing, the captain of Si Li, except for the different names, is the same as the history of the assassin.

The biggest difference between the history of the assassin and the state pastor is the issue of military power.

The third is that the Sili Lieutenant Department, even if the other armies can successfully take Zuo Fengyi and Hongnong County, there are still Right Fufeng and Jing Zhaoyin who have not taken it.

To put it simply, it is the Lieutenant Department of the Division, and it has not been completely taken down.

Fourth, Cao Cao will go back to relieve his breath, and he will definitely lead his troops to attack the Sili Captain's Department in order to prepare to recapture the Sili Captain's Department.

In this way, Zhang Yan's ambitions can be reduced.

After all, Zhang Yan used to be a pastor of Qingzhou and a prince, although he was defeated by Zhao Feng and Lu Bu at the beginning, and secretly took refuge in Zhao Feng.

But as a lieutenant of Si Li, he has been living a stable life for too long, and he has been instigated by his subordinates, and he may have ambitions again.

You must know that the department is under the school and the lieutenant department, but the Guanzhong area is rich in products and fertile land.

The only drawback, presumably, is the problem of insufficient population.

Of course, this only drawback, for Zhao Feng, is a good thing, the population is small, the family and the strong are also few, and in the future, the land of the division and the school captain can be strictly controlled.

Zhao Feng pondered for a moment and said to Xiong Dao: "Go and call Huang Zhong and Wei Yan to discuss the matter." ”

Xiong Da bowed his hand to Zhao Feng: "No! ”

After speaking, he turned around and withdrew from the Chinese army's big tent.

Less than a quarter of an hour.

Xiong Da, Huang Zhong, and Wei Yan walked into the Chinese army tent together.

Xiong Da bowed his hand to Zhao Feng to show that he had completed the task, and then returned to his position and stood still.

Huang Zhong and Wei Yan bowed their hands to Zhao Feng at the same time: "The lord summoned me to come, what do you command?" ”
