Cao Jun's offensive and defensive casualties in Zhuxian County were not small, but there were not too many people killed directly, and many of them were only slightly injured.

In the era of the Three Kingdoms at the end of the Han Dynasty, in fact, medical skills were not developed, and many soldiers who were injured on the battlefield had only one fate, that is, death.

Some soldiers who are seriously injured will naturally die in pain if they are not well treated, while some soldiers who seem to be not seriously injured, although some people can rely on their self-healing ability and barely survive, most of them will still die due to various accidents such as infection.

Even if you don't pass away, you will have serious sequelae.

Although Cao Cao is not a ruthless person, he also values the soldiers under his command, and generally those who are not seriously injured will be brought with them, but now they are in a hurry, and those who are injured and can't keep up with the team, Cao Cao can only leave them behind.

Even some grain and grass were heavy and could not be carried, Cao Cao gritted his teeth and ordered people to burn them all, and he didn't want to leave them to Yuan Yao's men and horses.

As for Yuan Yao, he pursued all the way behind Cao Jun.

He had already learned that the main force of Cao's army was ahead, but he was not in a hurry to find trouble with Cao Cao.

Although Cao Cao blindly retreated, he always had more than 10,000 soldiers and horses in his hands, whether it was the strength of the army or the ability of the generals, they were far superior to Yuan Yao.

Anyway, Yuan Yao didn't expect his men to be able to defeat Cao Cao, his purpose was only to force Cao Cao to retreat, disturb Cao Cao's spirit, and make him not idle for a moment, even if he led his soldiers and horses back to Xuchang, he was also a group of tired soldiers.

Yuan Yao could only give Lu Bu some help like this.

I hope that Lu Bu, an old boy, can enter Xuchang City before Cao Jun returns to help.

The two sides retreated and chased after each other, and there was a stalemate for several days, and there was no fighting.

Seeing that Cao Jun had already entered the territory of Yuzhou, if he continued to pursue further, it would be difficult for the people on Yuan Yao's side to retreat.

Yuan Yao could only give up, lead his soldiers and horses, and retreat to Zhuxian.

However, although the others withdrew, they left some scout spies behind and stayed in Yuzhou, so that they could transmit the information from Xuchang back as soon as possible.

As soon as Yuan Yao's men and horses left, the pressure on Cao Cao's side immediately became much less, and after a little rest, he went straight to Xuchang without stopping.

In Cao Cao's heart, he still cares about Xuchang's dynamics, and he can't allow him to rest too much.

Yuan Yao was anxious and waited for his spies to send information in Zhu County.

After waiting for three days, there was finally news coming back from Xuchang, which made Yuan Yao, Ji Ling and others excited.

They are eager to know whether Lu Bu has defeated Xuchang or not.

In case Lu Bu really took Xuchang, this would be excellent for Yuan Yao, and it would be good news for Yuan Shu's entire force.

But after the news came, it made Yuan Yao and others regret that Xuchang was not broken by Lu Bu.

Yuan Yao still gave Lu Bu too high expectations, although Lu Bu's personal bravery is really good, it can be said that he is the champion of the three armies, no one can match, but when it comes to marching and fighting, attacking cities and pulling out villages, Lu Bu's ability is quite mediocre.

Rao is assisted by famous generals such as Zhang Liao and Gao Shun, and it is too difficult for Lu Bu to turn over.

Although Cao Cao's soldiers and horses were restrained by Yuan Yao for a while, it also promoted Cao Cao's footsteps, and Cao's army retreated all the way to Xuchang, so he arrived in Xuchang one step ahead of Lu Bu's footmen.

Originally, Lu Bu planned to wait for his infantry to arrive, and immediately launched an attack on Xuchang, but before he could attack, he was attacked by the vanguard army led by Xiahoudun.

But it is also a coincidence that Xiahoudun only has 4,000 people, and after he returned to Xuchang, he thought that Lu Bu was fighting with Xuchang, and he didn't dare to slack off for a moment, and he didn't even stop at anything, and directly clashed with Lu Bu's army outside Xuchang City.

The result can naturally be imagined, where is Lu Bu's 4,000 elite cavalry comparable to Xiahoudun's 4,000 long journey, tired and sleepy foot soldiers.

After a battle, Xiahoudun was defeated.

If it weren't for Xun Yu in the city to open the city to rescue and kill him from behind, I was afraid that Xiahoudun's men and horses would be destroyed by Lu Bu on the spot.

And Lu Bu encountered the front and back attacks of Xiahoudun and Xun Yu, and he didn't dare to hold it up for a while, so he could only rely on the strong mobility of the cavalry to break through the encirclement and kill from Xiahoudun's encirclement.

After knowing that Cao Cao had reinforcements, Lu Bu did not dare to stay outside Xuchang City, so he thought about meeting his main force first. Wait for the main army to arrive, and then make plans.

In this way, Lu Bu made a detour again, planning to go back to the Yanzhou area.

But before he could go far, he encountered Cao Cao's main army that rushed all the way.

Another encounter between the two sides.

It's just that this time Cao Cao also didn't take advantage of anything, although he had tens of thousands of soldiers and horses, and had an advantage in numbers, but in the face of Lu Bu's cavalry charge, it was still difficult to resist.

After losing nearly half of his manpower, he reluctantly beat Lu Bu away.

But Cao Cao didn't dare to chase with people, firstly, he didn't have many cavalry, and he couldn't chase Lu Bu, and secondly, even if he pursued, Cao Cao himself would not be able to protect, so how could he continue to fight with Lu Bu.

He could only run back to Xuchang City to recuperate, and this time he went south to crusade against Yuan Shu, but instead of establishing an inch of skill, he lost more than half of the tens of thousands of soldiers and horses he had cultivated with great difficulty, and lost more than half of them, working the people and losing money.

As for Lu Bu, although more than half of the four thousand elite cavalry were lost and Xuchang City was not captured, he was not discouraged, after knowing that Cao Cao's forces had been greatly reduced and there was no way to pursue him.

Lü Buyi improved his goal of attacking Xuchang, but instead set his target on Peiguo, Liang and other places that were relatively close to Xuzhou.

These counties were far from Xuchang, but close to Lü Bu's Xuzhou, and Cao Cao's soldiers and horses could not support them in a short time, and Lü Bu could easily rely on his own soldiers and horses to occupy these places.

In just a few days, Lü Bu ordered Zhang Liao and others to attack all parts of Yanzhou in batches, and even took twelve cities.

When the news came back to Xuchang, Cao Cao was shocked, if it hadn't been for the great defeat just now, and the autumn harvest, he couldn't draw more troops at all, and Cao Cao even wanted to go to Lu Bu immediately to take revenge.

And when the news came back to Zhu County, Yuan Yao was happy.

Although Lu Bu was quite disappointed that he did not defeat Xuchang, it was worth the trip for Lu Bu to retreat and seize Yanzhou.

I thought to myself, Lu Bu is not too stupid.

As soon as Lu Bu left, Cao Cao was defeated and retreated, and the crisis in Huaibei was temporarily lifted.

Yuan Yao's heart was finally relieved for the time being.
