Faced with the sneak attack army of Liu Pi and Gong Du, who suddenly appeared in the southeast of Xudu, Cao Cao was really a little caught off guard.

But Cao Cao still didn't dare to easily mobilize Xiahoudun from the Changshe side to come back to help, so he could only transfer Hao Zhao, who was stationed in Chen State, to lead troops back to Xu Du, but Hao Zhao's side actually had six or seven thousand troops, and he might not be able to give Xu Du much support.

But Cao Cao couldn't care about anything else for a while, and the rest could only be used by recruiting young and strong soldiers and private soldiers from various clans in Xudu.

However, under Cao Cao's construction, Xu Du can also be regarded as a big city, so it is also a little difficult for Liu Pi and Gong Du to easily capture Xu Du, after all, the meaning of their visit this time is only to attract Cao Cao's attention.

But then another piece of news reached Xu Du, so that Cao Cao could only make up his mind to give up Xu Du, and the whole army retreated.

Although Cao Cao had already thought that Zhu Wei's next offensive target would be himself, he didn't expect Zhu Wei's offensive to be so overwhelming.

Even if the main force of Zhu Wei's army was stationed in Huanrong County, Liu Pi and Gong Du from Runan County had already attacked Xu Du's army, but then another piece of news made Cao Cao's heart tremble.

At the same time that the army of Liu Pi and Gong Du suddenly appeared on the side of Xu Du, news soon came from the side of Liang State, and the main general of the Cao army stationed in Liang State took the initiative to surrender to Suiyang City, so Cao Cao's defense line set up in Liang State suddenly opened a big hole.

Subsequently, Zhu Weijun's Huainan Battalion of Huang Zhong's Department and Taishi Ci's Shenjian Battalion, plus Zang Ba's soldiers and horses of Taishan County, easily entered Suiyang City, and then sent troops to attack some of the remaining counties of Liang State that refused to follow Che Xuan to surrender.

In this way, Cao Cao's defensive line in the east almost completely collapsed.

Hao Zhao on Chen's side had already come to the rescue of Xu Du, so the land of Chen's land was almost abandoned by Cao Cao, even if there was still a defense line garrisoned by Cao's army general Dong Heng in Jiyin County, but it was no longer able to resist Huang Zhong and Tai Shici's attack on the hinterland of Yanzhou.

Of course, this is not the most troublesome problem, what makes Cao Cao most nervous is that after Zhu Weijun captures Liang State, the next target is Chen Liujun, so it is very likely to block Cao Cao's route to Puyang.

Therefore, at this time, Cao Cao didn't care about Xu Du, so he directly retreated with the whole army, gave up Xu Du and retreated to Chenliu, and at the same time let Xiahoudun from the Changshe side and Hao Zhao from Chen Guolai retreat to the north together, and finally could join Cao Cao in Fengqiu and Sour Jujube Generation in Chenliu County.

In fact, the main force of Zhu Wei's army is now stationed in Rongyang, which can not only threaten Xudu, but also threaten Chenliu and Puyang, and it can be said that the land of Yanzhou is located on the Central Plains Plain, except for some cities that can be used as garrison fortresses, there is no other terrain that can resist the attack of Zhu Wei's army.

Now after Zhu Wei's army leaves the Tiger Prison Pass, facing Yanzhou, it is a state of flat Sichuan, and it can completely threaten Cao Cao's entire territory in Yanzhou.

This is also the reason why Cao Cao took the initiative to abandon Xu Du and Chen Liu, and was only ready to protect Puyang, which was not only close to Yuan Shao's Yecheng, but also a city that resisted the northern frontier of Yanzhou.

As long as Cao Cao can still hold Puyang City, he can at least protect some territory in the north of Yanzhou, so that Cao Cao can still have a chance to breathe.

At the same time, this Puyang City is also the seat of Yanzhou, and the city is relatively large, which is enough for Cao Cao to garrison troops in the city, which can give Cao Cao a certain confidence to resist the attack of Zhu Wei's army.

When Lü Bu attacked Yanzhou, he first occupied Puyang City, and then swept all the counties and counties in Yanzhou, leaving Cao Cao with only three cities left in Jiyin County, Fan County, Dongjun County, and Dong'e County, Shanyang County.

Later, Cao Cao led his troops back from the Xuzhou counterattack, and immediately went to fight the Puyang City occupied by Lu Bu, but Cao Cao and Lu Bu fought here for nearly three months and failed to defeat it, and then encountered a locust plague, and both sides had almost eaten the grain and grass, and Cao Cao could only return in vain.

Therefore, Puyang City is still a city that is easy to defend and difficult to attack, so if Cao Cao retreats directly to Puyang, he can gather the strength of the whole army and have an offensive and defensive battle with Zhu Wei's army in Puyang.

But Cao Cao didn't expect that he hadn't mobilized the population yet, and Zhu Weijun had already fought over, and at the same time, it was not the main force of Zhu Weijun who made the first move, but it made him feel a little broken.

This forced Cao Cao to garrison in the area of Fengqiu and Sujube first to resist the possible attack of Zhu Wei's army.

The land of sour jujube is the place where Liu Dai, Liu Dai, Kong Ling, Zhang Miao, Zhang Miao, Zhang Chao, Zhang Chao, Qiaomao, Shanyang, Bao Xin, and Cao Cao, both of the Dongzhou Alliance, and Cao Cao initiated the discussion of the Dong Alliance, which can also be regarded as the main way for Zhu Wei's army to attack Yanzhou out of the Tiger Pass.

Therefore, in order to prevent Zhu Wei's army from pouring into Yanzhou in one fell swoop, Cao Cao naturally needed to find a place to block Zhu Wei's army, so that he could take a breath first and ease the current situation of being broken everywhere.

Now Cao Cao's Yanzhou defense line has suddenly become fragmented, even if Cao Cao wants to withdraw Puyang City, he needs to concentrate the forces on Yanzhou's side first, otherwise his troops are scattered everywhere, and they will only be broken by Zhu Weijun taking advantage of the situation.

However, with Cao Cao's initiative to retreat, Liu Pi and Gong Du took advantage of it in vain, and they only used their nearly 10,000 troops to capture Xudu.

After Huang Zhong, Tai Shi Ci, and Zang Ba captured the Liang State, they first divided Huang Zhong's troops to attack the land of the Chen State, and then still let Che Zhou stay in the Liang State, and Tai Shi Ci and Zang Ba really sent troops to Chen at the first time.

But on the side of Xiangyi County, Tai Shici and Zang Ba met the soldiers and horses of Hao Zhao, the guard general of the Cao army transferred by Chen Guo.

Hao Zhao occupied Xiangyi County, and he could be regarded as trying his best to block the Zhu Wei army under Tai Shici and Zang Ba from continuing to advance, and he wanted to buy time for Cao Cao to retreat to the land of sour jujubes.

This Hao Zhao is not a loss is a well-known general in history, he used Xiangyi County as the foundation, and rationally used the five or six thousand Cao troops brought by his subordinates from Chen State, which really made Tai Shici and Zang Ba's army fail to break through for a while.

On the one hand, Hao Zhao's defense ability is really good, and on the other hand, Tai Shici and Zang Ba did not prepare many siege equipment, so they didn't expect to encounter a hard stubble like Hao Zhao blocking the way here.

In addition, because the Tonghui River has formed a rich water system on the side of Xiangyi County, it has also formed a complex topographical environment in the local area, so Tai Shici and Zang Ba are indeed unable to easily pass through the blocking line formed by Hao Zhao's occupation of Xiangyi City.

However, the battle situation here cannot affect the overall situation.

Although Zhu Wei temporarily stopped the army on Rongyang's side, he was waiting for Liu Bi, Gong Du, Huang Zhong, and Tai Shici to move.

Therefore, after several armies on the eastern front broke through the defense line of the Cao army, Zhu Wei checked the movements of the Cao army through the map of the Three Kingdoms game system, and according to the military movements of the Cao army, he led the main army to the direction of the sour date......
