After all, this time Yuan Shao attacked Liu Bei, but Xuzhou and Yanzhou sent troops at the same time, and he personally commanded the battle in Xuzhou, while Yanzhou was led by his eldest son Yuan Tan and the other two of the four court pillars in Hebei.

Since Yuan Shao's side has attracted all of Liu Bei's attention, then on the Yanzhou side, Liu Bei can dispatch a lot fewer soldiers and horses, so that Yuan Tan wants to defeat Yanzhou, and the difficulty is much smaller.

As long as Yuan Tan can threaten Yanzhou, Liu Bei on the Xuzhou side has to worry about it, and even dispatches the soldiers and horses on the Xuzhou side to Yanzhou to support.

In this way, Yuan Shao's pressure is less.

Yuan Shao's side has just finished his busy work, and he has dealt with some defensive measures.

Guan Yu outside the city had already united with Zhao Yun to lead an army of 20,000 to appear under the city of Tan County.

Although Tan County is the seat of Donghai County, Donghai County is not a big county in Xuzhou, and the county seat is not a big city with thick walls.

It's just an ordinary small city, and it's a little inferior to Picheng.

However, it is a county town, and it is not easy to fight it.

After Guan Yu and Zhao Yun's 20,000 troops appeared in Tanxian, they did not immediately start attacking the city, but set up camp before they began to arrange their troops.

After preparing all the preparations, Guan Yu began to let the soldiers and horses appear under the city one after another, and beat the war drums, attracting the attention of Yuan Jun on the city tower.

Wen Chou and Jiang Qi were scanning back and forth on the city tower, on the one hand, they were checking how many enemy troops there were under the city, and on the other hand, they were also thinking about how their own men could break the attack of Guan Yu and others.

Guan Yu appeared under the city, sat down and sat down with a jujube war horse majestic and high-spirited, he held the Qinglong Yanyue Sword with one hand, and his green robe was majestic.

After brushing his extremely long beard with his hand, Guan Yu raised the strength on his body, roared, and began to shout at the city tower.

"The defenders on the city tower listen, wait for the city to open and surrender within an hour, otherwise they will be killed in the city, and they will not be spared!"

Guan Yu was still Sven, and he didn't say arrogant words like slaughtering the city.

After all, this Tan County also belonged to Liu Bei's rule, and the people in the city still had a little affection for Liu Bei, so Guan Yu naturally would not do such a bad thing.

However, Guan Yu is no less angry than others, after all, Yuan Shao took advantage of the danger of others and led the army to attack Xuzhou at this moment, which also made Guan Yu very ashamed.

"The thief is going to be rampant, if you have the ability, you will attack and fight the city, what kind of hero is the power of the tongue under the city?"

Although he is at a disadvantage, Wen Chou also hates Guan Yu very much, and he can't even say that he hates it, he simply hates it.

After all, his good brother Yan Liang died under Guan Yu's knife.

If it weren't for the fact that they were at a disadvantage at this time, according to Wen Chou's temperament, they would have to go out of the city and fight Guan Yu for 300 rounds.

Guan Yu under the city was called by Wen Chou on the city tower, but he didn't answer Wen Chou immediately.

Guan Yu was not in a hurry to attack the city.

Because they have the advantage at this time, Guan Yuzhi needs to surround this Tan County, cut off the grain and grass in the city, and without the support of grain and grass from other places, this Tan County will not last long at all, and within two months, he will take the initiative to go out of the city and surrender.

Two months may be a long time for others, but for Guan Yu, he has to wait, and he knows that there are generals such as Wen Chou in this city, and trapping these people is equivalent to cutting off Yuan Shao's arm.

At this time, Guan Yu didn't know that Yuan Shao, the commander of the Yuan army, was also in this Tan County, if he knew that Yuan Shao was also here, he was afraid that even the 10,000 horses and horses left in Xiapi City would be brought over by Guan Yu and attack this Tan County, as long as Yuan Shao was killed, the battle of Xuzhou would be pacified.

The reason why Guan Yu was not in a hurry to attack the city was also because Guan Yu knew that in Xuzhou, the Yuan army only sent 60,000 troops over.

In the battle of Xiapicheng, Yuan's army suffered heavy losses, and now there are less than 20,000 soldiers and horses in this Tan County.

If such a small number of people went out of the city to fight, they were not Guan Yu's opponents at all.

Therefore, they will definitely stick to the city and wait for Guan Yu to take the initiative to attack.

And they can't wait for reinforcements in a short time, after all, there are no soldiers and horses near Xuzhou, and if they want reinforcements, they can only mobilize troops and horses from Qingzhou at the earliest.

In this way, Guan Yu doesn't have to worry, these people will have reinforcements, they only need to besiege Tanxian, and when the people in the county can't bear it on their own, they will go out of the city to fight with them.

After Guan Yu did not rush to attack Tan County, he just let his men and horses surround the entire Tan County. After waiting for two days without attacking, the two sides temporarily confronted each other in Tanxian.

Guan Yu is not in a hurry. Yuan Shao was naturally not in a hurry, he was waiting, waiting for his nephew Gao Gan from Qingzhou to lead an army of 20,000 to come to support.

But they were not in a hurry, and Liu Zheng, who stayed aside and waited to act as a yellow bird, was extremely good.

If the praying mantis and the cicada don't fight, it's not easy for him to shoot.

After two days, after seeing that Guan Yu and Yuan Shao's men and horses were still moving, Liu Zheng couldn't bear the loneliness and was ready to strike first.

It's not that he doesn't want to wait. But his soldiers and horses have already been dispatched, and they can still hide for a day or two, and they will inevitably be exposed after a long time.

Once his men and horses are detected by Liu Bei, Guan Yu, Yuan Shao and others, it is unlikely that he wants to make another surprise attack and catch his opponent off guard.

Therefore, Liu Zheng was a little anxious, and he was unwilling to continue to wait here for Guan Yu and Yuan Shao to fight, if they didn't fight, then Liu Zheng would help them fight.

Guan Yu annexed Tan County and confronted Yuan Shao's men and horses, but Xiapi City was empty, leaving 10,000 remnants led by Sun Shao to defend it.

At this time, Liu Zheng led 10,000 horses of Zang Ba, as well as his own 3,000 elite traps and 2,000 brocade guards.

These horses, if they want to attack Picheng, although they are a little too big, they may not be able to succeed.

After thinking about it again, Liu Zheng sent someone to Guan Hai and ordered him to lead 10,000 horses to cooperate with Zang Ba to attack Xiapi.

At the same time, he let Zang Ba's 10,000 people go to besiege Xiapi City.

Then he let Wenpin's men and horses ambush Xuzhou on the way to Xiapi to prevent Liu Bei from continuing to increase troops in Xuzhou to support Xiapi.

And Liu Zheng himself, at this time, led his 5,000 troops of the trap camp and Jinyi Wei to guard the road between Tanxian and Xiapi City.

He wants to set up an ambush here to fight the Guan Yu army that has returned to help.

Once something happens to Xiapi, it is impossible for Guan Yu not to come back.
