Just when Liu Zhang was still angrily reprimanding Gao Pei.

Yan Pu, who was standing beside Liu Zhang, immediately thought of something, and immediately said something to Liu Zhang.

Liu Zhang's attitude towards Zhang Lu and others is not good.

However, he still trusts Yan Pu.

After all, Yan Pu is a local, and after he is a local big family, his identity and status are all here.

Compared with Zhang Lu and others, Yan Pu has no ambition and is more in line with the identity of a strategist.

As a son, Liu Zhang also wanted to win over Yan Pu and dig Yan Pu to his side from Zhang Lu.

After hearing Yan Pu's words at this time, Liu Zhang was not stupid, and immediately realized it.

"It's not good, this may be the enemy's plan to attack the west, follow me back to the north gate immediately!"

Liu Zhang did not delay here, and gave up at the moment to continue to blame Gao Pei. Instead, he ordered Gao Pei to take the rest of his soldiers and horses to garrison here.

Liu Zhang himself immediately joined Zhang Lu and others from here to the direction of the north of the city.

In the north of the city, there are Yan Yan and Zhang Ren guarding the town, although Liu Zhang does not think that Guan Yu's men and horses will break South Zhengcheng in such a short time.

However, if Guan Yuda really wanted to attack the east and the west from the beginning, and if he acted on both sides, he would attack with all his might, even if Yan Yan and Zhang Ren were guarded, there would be some difficulties.

What Yan Pu said really happened, when Ma Chao defeated these legions led by Deng Xian in the south of the city, he also sent people to convey a signal to Guan Yu.

Guan Yu knew that Ma Chao was fighting with Liu Zhang's men in the city at this time, and knew that this side in the south of the city would definitely attract the attention of some of the city soldiers.

Taking advantage of this time, Guan Yu knew that it was the best opportunity to attack Nanzheng.

Only when attacking at this time will the guards in the city be the weakest, otherwise at other times, it will not be so easy to take down this Nanzheng City.

Guan Yu let his soldiers attack the city tower.

The 30,000-strong army had already surrounded the north side of the city, and at this time they were only waiting for Guan Yu's order.

With Guan Yu's order, these soldiers rushed to the city gate frantically, and an offensive and defensive battle broke out in the north of Nanzheng City.

The attack of the 30,000-strong army did make the defenders in Nanzheng City feel tricky.

At this time, on the city tower, in charge of defense in the north of the city was Zhang Lu's brother Zhang Wei.

Zhang Wei is Zhang Lu's most trusted person, except for his own adviser Yan Pu, the entire army in Hanzhong is managed by Zhang Wei.

At this time, it was also Zhang Wei who was fully responsible for the defense of the north of the city, plus Yan Yan's assistance.

Guan Yu's army rushed up, Zhang Wei still had a little ability, and his ability to command soldiers and horses was barely able to block the army led by Guan Yu.

At least, these horses, unable to break through the protection of the city gates, rushed up from under the city with siege equipment.

Blocking the small half an hour, for Zhang Wei, it was still very easy.

After all, there are a lot of soldiers in the city, and all of them are deployed on the side of the north city gate, and tens of thousands of troops are here, even if one person throws stones, he can also scare Guan Yu's men and horses.

When Zhang Lu and Liu Zhang returned here, Guan Yu was still commanding his soldiers to forcibly attack the city.

After losing thousands of people and not being able to defeat Hanzhong City at all, Guan Yu saw Liu Zhang, Zhang Lu and others return to the city tower, and then he realized that it was quite difficult to defeat this Hanzhong.

Knowing that there were a lot of soldiers in the city, Guan Yu shook his head, and then went to ask Liu Bei for advice.

After all, this time Liu Bei personally supervised the battle here, even if Guan Yu was the main general, there were some times when he needed to ask his eldest brother before he could make up his mind.

After Guan Yu conveyed the news of the retreat to Liu Bei, Liu Bei didn't say anything, and he was watching the whole battle.

Naturally, it is also clear that in the current situation, it is very difficult to directly defeat Hanzhong, and a strong attack will only increase the casualties of these soldiers brought by Liu Bei.

Instead of continuing to attack the city here and losing soldiers, it is better to take Liu Bei's original plan and first surround this Hanzhong city, cut off the connection between Hanzhong and Yizhou, and trap Zhang Lu and Liu Zhang and others in this southern Zheng city.

It won't be long before they will go out of the city and surrender on their own.

Anyway, Ma Chao had already launched an attack on Liu Zhang's soldiers and horses just now, and killed a lot of Liu Zhang's soldiers and horses, which had already given Liu Bei an advantage.

"Withdraw for the time being."

Liu Bei gave Guan Yu an order.

After Guan Yu understood what Liu Bei meant, he did not continue to let his soldiers attack Nanzheng City.

When Zhang Lu, Liu Zhang and others rushed to the city gate, Guan Yu had already let his soldiers withdraw from under the siege gate.

A big war didn't take long for it to die down.

Liu Zhang, Zhang Lu and others, who returned to the north city gate, were relieved to see that Guan Yu did not hit the city gate.

However, although Guan Yu did not defeat Nanzheng City, when Guan Yu launched an attack with soldiers and horses just now, it had already made Liu Zhang, Zhang Lu and others nervous.

After all, now the soldiers and horses brought by Guan Yu have surrounded Nanzheng City, and the four city walls are full of Guan Yu's soldiers and horses.

Although Liu Zhang and Zhang Lu still had a lot of soldiers and horses in the city, they were still able to resist one or two by relying on the city wall. If you go out of town, the odds are not great.

Now that they're trapped here, they'll have to think of something else.

However, a big battle just happened, and Liu Zhang, Zhang Lu and others all lost their soldiers and horses.

They didn't think of fighting back for the time being, or going out of the city to fight Guan Yu's soldiers and horses at this time.

After all, morale is low, and if you go out of the city, you will only be defeated by Guan Yu's men and horses in one fell swoop.

The two sides also temporarily withdrew their troops and rested.

The Great Battle that took place outside the city of Nanzheng.

It's only been half a day.

The news reached Liu Zheng's ears through Liu Zheng's spies.

At this time, Liu Zheng was bringing soldiers and horses to greet Gan Ning.

And Gan Ning happened to personally lead his 20,000 troops to approach Nanzheng City, wanting to prevent Liu Bei from suddenly launching an attack on Nanzheng and fighting a blitzkrieg.

When the news reached the ears of Liu Zheng and Gan Ning, Liu Zheng was immediately stunned and surprised.

"What? Guan Yu's guy actually really launched an attack on Nan Zhengcheng. ”

"Didn't he have only fifty or sixty thousand horses under his command? With this point, the people want to take down Nanzheng City. ”

When he heard the news for the first time, Liu Zheng seemed a little unconvinced.

If it were his own, the same force would not be advantageous.

But now, the spies at the front continue to relay the situation outside Nanzheng City to Gan Ning's camp.

Liu Zheng had to believe it, and at the same time, he immediately reacted quickly, increased the ability of spies to detect intelligence, and ordered Gan Ning to lead a part of the soldiers and horses to approach Nanzheng City quickly.
