With Lu Bu's consent, Zang Ba naturally acted quickly.

Scatter around the city with hundreds of soldiers, and then have them use rockets to shoot at the moat below.

Ignite the oil in the moat.

......Suddenly, hundreds of rockets burning from arrows were shot down by hundreds of soldiers at the moat under the city.

The rocket was fast, and soon it hit the moat beneath the city.

The oil floating in the moat burns quickly when it encounters fire.

Moreover, it was extremely fast, and soon spread to the entire moat.

In an instant, the wide and deep moat around Yi County turned into a river of fire, and the scorching temperature and great flames made people fear its destructive power when they saw it.

At this time, Yuan Shao's soldiers, who were attacking the city without fear of death, naturally did not have time to escape, and were instantly shrouded in the fire caused by the fire burned by the fire in the moat.

The fire was extremely hot, they were just flesh and blood, so naturally they couldn't stand such a scorching fire!

At the same time, the scorching fire also woke them up in an instant.

Due to the stimulation of Yuan Shaoyu's rich reward, he has now completely sobered up.

Although Yuan Shao's reward for them is rich and coveted by them, they must also have this life to get!

The siege soldiers who have now come to their senses are no longer the hot-headed people who are not afraid of death, but have returned to the ordinary people who are afraid of life and death.

Facing the burning oil around them, they were afraid, and then they retreated.

They didn't want to attack the city anymore now, and then they would get a rich reward that Yuan Shao promised them that was extremely difficult to obtain!

As the first besieging soldier retreated, suddenly, it was out of control.

One by one, they threw away their armor and retreated towards the back.

Fortunately, the oil was burning in the moat, and they were not splashed or splashed on them by the oil on the moat.

As long as they flee quickly, do not breathe in the choking smell of burning oil, and then quickly extinguish the fire on their bodies, they can still escape their lives.

It's just that the hair on their heads and the clothes on their bodies will be burned by the scorching fire, and they will even be disfigured.

In order to be able to escape his life, the siege soldiers on Yuan Shao's side now became very frightened, crying for their fathers and mothers, and retreated towards the back as quickly as possible.

As a result, there was a huge chaos, and many soldiers who could have escaped their lives were pushed down the moat by their own soldiers.

The moat is full of fire oil, and the end of the soldiers who fell into the moat can be imagined.

As the fire oil in the moat continued to burn, the ladders and planks that Yuan Shao's soldiers had built at both ends of the moat were also quickly burned.

The soldiers, who didn't have time to escape, fell into the moat below, and instantly became a burning man, and then a pile of coke.

Now, the enemy was already scrambling to retreat for fear of the fire in the moat, and Lu Bu, who was condescendingly admiring the enemy's tragic condition above the head of Yi County, naturally would not let go of this opportunity to kill the enemy and make the enemy even fewer.

Therefore, Lu Bu hurriedly ordered his soldiers to use sharp arrows, throwing stones, and rolling logs to greet the enemy soldiers who fled in confusion under the city.

Yuan Shao's besieging soldiers suffered heavy casualties under so many heavy blows and killings.

In the end, there are not too many people who can escape their lives!

The number of dead has reached 20,000!

Let Yuan Shao, who was commanding his own army to attack the city in the rear, see it, and his face was immediately hideous, and he was furious!

Stimulated by the generous reward he promised, he had absolute confidence that he would be able to break through Yi County, and the speed of the attack was extremely fast.

But now, it is such a completely different result, how did Yuan Shao accept it?

Yuan Shao now hates Lu Bu even more, hates Lu Bu's cunning, hates Lu Bu's ruthlessness, and even used fire oil to burn his 20,000 troops at once!

At the same time, Yuan Shao looked at his own soldiers who were too late to escape now, and then fell into the moat, they turned into burning people, and they did not die for a while, but were burned in the moat and screamed!

Listening to their screams, Yuan Shao couldn't help but tremble.

It's as if that's how you die when you die!

Because, that kind of death is as cruel as being cut to death by a thousand knives!

However, Yuan Shao soon forced himself to come back to his senses.

Because, Yuan Shao looked down on Lu Bu extremely much, so he naturally refused to admit defeat to Lu Bu, not to mention that Lu Bu's current methods of dealing with his siege soldiers made him feel terrified!

Yuan Shaocai didn't want to feel this way.

Then, Yuan Shao wanted to order his own army to continue the siege.

Yuan Shao doesn't believe it, there are so many troops on his side, will he not be able to break through Yi County?!

However, when Yuan Shao wanted to order his soldiers to continue the siege of the city, he was stopped by Fu Zhi, who was traveling north with Yuan Shao.

Now that it has reached such a point, where is the right place to continue the siege?

Not to mention, the fire oil in the moats around Yi County has not been completely burned out, and it continues to burn.

Isn't Yuan Shao messing around with the lives of his own soldiers?

For the sake of the lives of his own soldiers, as Yuan Shao's subordinate, he naturally does not allow Yuan Shao to mess around like this!

What's more, if there was no army that had just gathered, and he lost 100,000 troops when he fought against Cao Cao on Guandu, then how long could Yuan Shao's foundation last?!

It is better to withdraw for the time being, and wait until you think of a perfect siege plan before continuing the siege.

Guo Tu, Feng Ji, Judge, Xin Ping and other strategists who also followed Yuan Shao to the north, although they did not agree with Fu Zhu, in order to get more power here in Yuan Shao, they wanted to kill Fu Zhu as soon as possible, but they also knew the severity!

If Yuan Shao recklessly let the remaining 80,000 soldiers attack the city, it would be good if he could break through Yi County, but what if he couldn't break through Yi County?!

At that time, without these 80,000 soldiers, it will be the end of Yuan Shao's Hebei foundation!

They are loyal to Yuan Shao, and the status they have gained here will also be gone, so they don't want this!

Therefore, they temporarily put aside their disagreement with Fu Zhu and jointly persuaded Yuan Shao to withdraw from the army.

Although Yuan Shao was carried away by hatred, he wanted to break through Yi County as soon as possible and kill Lu Bu and Tian Feng in Yi County.

However, under the persuasion of Fu Zhu, Guo Tu and others, although Yuan Shao was unwilling, he also knew the severity.

Therefore, he ordered a pro-soldier Ming Jin to withdraw his troops and temporarily gave up his plan to attack Yi County.

With Yuan Shao's retreat, it means that the first siege of Yuan Shao's army can be declared a failure.

This siege battle caused Yuan Shao to lose 20,000 soldiers!

This is a great casualty, which makes Yuan Shao, including the civil and military forces under Yuan Shao's account, and the army all shrouded in a dark cloud, which will not disperse for a long time!

Lu Bu, who was above the head of Yixian County, saw that Yuan Shao led the army to retreat, and he did not take advantage of the victory to pursue.

Because, Yuan Shao still has 80,000 troops left, if he rushes out of the city like this, even if he can destroy Yuan Shao's 80,000 army, he will suffer heavy losses!

Lu Bu didn't want this.

Therefore, seeing that Yuan Shao had already led the army away, Lu Bu ordered his soldiers to clean up the battlefield.

Bury the corpses of our soldiers!

Then, pack up the weapons, armor and other strategic materials discarded by Yuan Shao's army.

After all, no matter how small a mosquito leg is, it is meat!

Not to mention, there is still a lot of this 'meat', and it was picked up for nothing, so Lu Bu naturally wouldn't let it go in vain.
