Now Zhu Wei thinks about the beginning of the Battle of Guandu in the original history, perhaps in June 199 AD, Yuan Shao had no intention of moving troops, and Yuan Shao still spent half a year to stabilize the territory in the north.

It is likely that Cao Cao himself analyzed the possibility of Yuan Shao going south according to the situation, which made a lot of preparations before Yuan Shao sent troops, and finally lured Yuan Shao to Guandu to have a decisive battle with him.

Of course, as far as the original historical development is concerned, even if Cao Cao had made a lot of preparations in advance, he was still a little lucky to win the battle of Guandu.

When the two armies of Cao and Yuan faced each other in the Battle of Guandu, the other forces in the Central Plains, such as Sun Ce and Liu Biao, almost all sat back and watched the tiger fight without any action, perhaps they didn't expect Cao Cao to win at first, and they were still thinking about how Cao Cao should face Yuan Shao if Cao Cao was defeated.

Therefore, they had no intention of sending troops to Cao Cao, they just hoped that Cao Cao could contain Yuan Shao more and give them some time to develop and grow.

Otherwise, even if they send troops to attack, Cao Cao will be difficult to parry, in the original history of the Guandu War in the middle and late stages, Cao Cao can no longer hold on, that is, relying on Xu You's surrender, he knew the military situation on Yuan Shao's side, so that Cao Cao reversed the situation by sneaking up on the Wuchao battle.

Well, having said so much about what happened in history, it's actually just vernacular.

After all, now that Zhu Wei controls the territory of Liu Bei and Sun Ce, it is naturally impossible to sit on the mountain and watch the tiger fight, and in terms of the current situation, Zhu Wei should make a move against Cao Cao earlier than Yuan Shao.

So as far as the location of the territory between Zhu Wei and Yuan Shao is concerned, what news changes have on Zhu Wei's side are not too much of a concern for Yuan Shao.

But on Cao Cao's side, he did not dare to relax in any way, it can be said that since the end of the first battle of Shouchun, Cao Cao has been prepared for Zhu Wei's possible attack on Xu Du.

For this reason, Cao Cao faced the line of Nanyang County in Jingzhou in Yingchuan County, and it was also like the fortifications prepared in Guandu in order to defend Yuan Shao in the original history, and several defensive lines were constructed.

Now Nanyang County is in the hands of Zhu Wei, so unlike when Liu Biao controlled Jingzhou in the original history, there was still a Nanyang County separated from Xu Du as a buffer zone.

Therefore, Zhu Wei can send troops into Yingchuan County at any time to threaten Xu Du, in fact, Zhu Wei's threat to Xu Du is greater than Yuan Shao's threat to Xu Du in the original history.

After all, Yuan Shao still had to face the Yellow River from the north and south, so Cao Cao only needed to control a few Yellow River crossings, which could have a somewhat blocking effect on the attack of Yuan Shao's army, so that Yuan Shao's army could not easily cross the Yellow River.

For example, in the Battle of Guandu, Cao Cao ordered Yu Ban to lead 2,000 cavalry to guard Yanjin, an important ferry on the south bank of the Yellow River, so that Yuan Shao's army could only cross the Yellow River from Baimajin, which was farther away, which triggered the Battle of Baima, Guan Yu beheaded Yan Liang and Zhu Wenchou's Three Kingdoms allusions.

But now if Zhu Wei attacks Yingchuan from Nanyang, Jingzhou, and then threatens Xudu, there is no Yellow River to block, at most, he will use Funiu Mountain and Tongbai Mountain to construct some mountain defense lines.

Therefore, after Cao Cao returned to the capital of the army in Shouchun, he had already begun to construct a defensive line in Yingchuan County, and at the same time sent a large number of fine works to probe the movements in Zhu Wei's territory.

Now that Cao Cao heard the news from Zhu Wei's side, he naturally didn't believe that Zhu Wei was going to use troops to Yizhou.

With the brains of Guo Jing, Xun Yu, Xun You, Cheng Yu and other strategists on Cao Cao's side, they all know that the army of Gan Ning and Zu Lang sent by Zhu Wei to attack Liu Zhang in Yizhou is enough to capture Yizhou, and there is no need to send more troops over.

So now that Zhu Wei has made such a move, Cao Cao feels that Zhu Wei is going to use troops on his side.

Therefore, Cao Cao immediately dispatched Xiahoudun, Li Dian, Yu Ban and other generals to lead the army to garrison Xiangcheng, which can be regarded as the hub city where Cao Cao constructed the first line of defense in Yingchuan County.

Xiangcheng is located in the eastern section of the Funiu Mountains, the southwest of the territory is a rolling shallow mountainous area, the north is a hilly area, the central and eastern part is a plain, and the overall topography is high in the west and low in the east.

The Cao army, with Xiahoudun as the main general, was stationed in Xiangcheng, so that it could radiate the four counties of Wuyang, Kunyang, Fathercheng, and Jiacheng in the southwest of Yingchuan County to defend it, so as to resist Zhu Wei's army that might enter Yingchuan from Ye County or Luyang County.

Among them, the father city is an important town in northern Chu in the Spring and Autumn Period, second only to the capital city of Chu in scale, and it is the capital city of the old Chu, so it also has a good city wall defense, and now it has become an important frontier city for the Cao army's garrison defense.

Then, Cao Cao dispatched Cao Ren, Xu Shang, Xu Huang, Lu Zhao and other generals to lead the army to garrison Yingyin, which is the central city of the second line of defense of Yingchuan, and then can radiate the defense of Yangzhai and Linying counties.

As for Cao Cao himself, he was in charge of Xudu, and he could also lead his troops to Xiangcheng at any time to resist Zhu Wei's possible army.

Of course, Cao Cao's soldiers stationed in Yingchuan are not all elite main forces, many of them are new soldiers, young and strong, and even Cao Cao's Tuntian soldiers placed in the local area.

It turned out that Cao Cao also learned Zhu Wei's Tuntian methods and wantonly tuntian in the land of Yingchuan, so he arranged Tuntian troops in many places.

It can be said that Cao Cao's defensive line against Zhu Wei in Yingchuan is a defensive line constructed in the name of Tuntian, which can raise troops in Tuntian on the one hand, and garrison troops to prepare for war on the other.

Now, according to his analysis of Zhu Wei's military movements, Cao Cao made the garrisons in these areas more inclined to prepare for war, and he specially dispatched Xiahoudun, Cao Ren and other generals to the past, and he could also command the army at any time to resist the invasion of Zhu Wei's army.

Of course, while Cao Cao was actively preparing for military defense, he couldn't help but think of using other tactics to delay the possibility of Zhu Wei sending troops.

Cao Cao is now actually in a state of recuperation, before the first battle of Shouchun Cao Cao also spent a lot of grain reserves, but after that, he did not get any harvest of grain and grass materials in Shouchun, so Cao Cao also needs time to re-reserve grain and grass, he also does not want any war, his current grain storage is not enough to support the war.

So during this time period, Cao Cao sent envoys from the Son of Heaven to Zhu Wei's side, which seemed to be for Zhu Wei's previous exploits in the battle to quell the rebellion against Yuan Shu in Shouchun, and brought a reward to Zhu Wei.

This time, Cao Cao was very generous in the name of the Son of Heaven, and he was given the post of Captain Zhu Wei, and he had the real power to record Shang Shushi, and added Zhu Wei as a hussar general, which was equivalent to making Zhu Wei's official position enter the ranks of the three princes at once, and he was second only to the highest-ranking general in military rank.

Cao Cao can be regarded as a great show of favor to Zhu Wei this time, Cao Cao himself is the official position of Sikong and the military position of the general of the chariot cavalry, and now Zhu Wei's official position is higher than him, perhaps Cao Cao just wants to use this kind of empty official position to suppress Zhu Wei's idea of moving troops.

After all, Zhu Wei had just obtained such an official position, and he turned around and used troops against Xu Du, wouldn't it be too much to say.

In fact, this was also Cao Cao's delaying tactic......
