Cao Cao's Yanzhou army lasted more than the Xuzhou army for an hour, and finally succeeded in withdrawing nine cloud ladders, suffering 5,000 casualties and more than 2,000 casualties to the central army defending the city.

Of course, most of them are the Tuntian Army and the Reserve Brigade, after all, their experience, equipment, and training intensity are much worse than those of the Central Army.

However, this is also the main reason why Lu Bu transferred them, that is, they are used for consumption, and Lu Bu can't afford to consume the main force of the Central Army.

In just three days of siege, the defenders of Tiger Prison Pass suffered nearly 5,000 casualties, and if the battle continued for a long time, the central army, which was inferior in numbers, would be under great pressure.

Because of the southward movement of the Xianbei people, the Tuntian army and the local garrison brigade in the Duliao and Bingzhou regions could not be mobilized.

The defenders of Tiger Pass could only recruit new troops and reserve troops from the Baling Battalion in Chang'an, and their combat effectiveness and equipment were significantly different from those of the main force, and they were even inferior to the Tuntian Army and local garrison brigades.

The fourth appearance of the Kwantung Coalition Army was Yuan Shao's Jizhou Army, and Yuan Shao also dispatched 25,000 people, the leader of the alliance! How could Cao Cao steal the limelight!

He even sent the first battalion of the general Koji Yi to serve as the main force for the siege.

Yuan Shao also used thirty ladders, and also chose the middle section of the city wall, but did not use the rushing car.

Yuan Shao's Xiandeng battalion was the most elite unit in the Jizhou army, and they were also equipped with 2,000 crossbows bought from Cao Cao, and the rest of the troops were still equipped with hard crossbows.

Koji Yi personally put on heavy armor and rushed to the city wall with hundreds of dead soldiers carrying a ladder, and shouted the slogan "Go first!" Go first! Unbeatable"

Xu Rong, who commanded the defense of the whole army at the head of the city, also showed no weakness, and the slogan of trapping the camp also resounded through the Tiger Prison Pass, "The will to trap the battle!" There is death and no life! Trapped! I'm invincible! ”

Both the offensive and defensive sides are the main elite, the fighting spirit is not inferior, the first battalion is also the best of the best, the hoplites wear heavy armor, can still quickly follow Koji Yi to climb to the top of the city, and the cooperation between several people is also very skillful.

In order to defeat the enemy, Xu Rong even reduced the proportion of the Tuntian Army, and the officers and soldiers of the First Division accounted for most of them.

This stalemate was repeated for a long time, until Yuan Shao felt that it was as long as Cao's army to attack the city, and then ordered Mingjin to withdraw his troops.

Koji Yi still commanded the first camp at the head of the city to withdraw from the city, and returned to the camp with more than a dozen ladders.

However, due to the fact that both sides invested the main forces, the battle was fierce, although it was the same time, the casualties of Yuan Shao's army were as high as six or seven thousand, and the same Central Army also suffered three thousand casualties. The generals on both sides were taken aback.

Since then, Yuan Shao has refused to let the first battalion fight. Xu Rong was also severely criticized by Lu Bu, can the officers and soldiers of the first division be used as meat shields?

And the seventh division, which was used for prohibition overnight, replaced the first division.

That night, the tiger-faced military advisor sent a secret letter to Lu Bu, which described in detail how he would perform this play tomorrow. The details and steps to be prepared by Lu Bu were emphasized again.

Lu Bu also had to admire the imagination of this tiger-faced military master was very good, and Lu Bu might not have thought of such a trick.

After dawn, the defenders of Tiger Prison Pass had breakfast early, and the sound of horns had already sounded from the Kwantung coalition army camp outside the city.

The Qingzhou Army began to attack the city half an hour earlier than usual, and in the words of the Tiger Mask Division, the Central Army had to fight hungry before it had breakfast.

The Kwantung princes who didn't know the truth were very impressed, why didn't they think of such a simple method!

The Qingzhou army also dispatched 25,000 people, also 30 ladders, and the general Chen Zhi personally commanded the siege.

The arrows of the central army at the head of the city were as dense as ever, except for the lack of large repeater attacks.

But no one noticed this, and people kept falling from arrows.

Another detail that no one paid attention to, the fallen soldiers were all lying on the ground, and few were facing the sky on their backs.

The wounded were also lying on the ground and groaning, and everyone found that the crossbow arrows shot by the Central Army had all been stripped of the metal arrows, and only a wooden arrow had been sharpened.

Many of the injured people used their own crossbow arrows to pierce their arms and thighs, of course, this action was done secretly while lying on the ground.

Braving the "rain of arrows" in the sky, thirty cloud ladders were still erected under the city wall by the tenacious Qingzhou army.

Hundreds of Qingzhou dead soldiers rushed to the city, and their courage was not inferior to that of Cao Jun and Jizhou Jun.

The corpses of the Qingzhou army were constantly thrown down from the city by the defenders, but the detail that no one noticed was that ten Qingzhou troops often rushed up and only dropped two or three corpses.

Today, the Central Army's efficiency in destroying the ladder is much lower than usual, so a large number of Qingzhou troops continue to rush to the city.

It's a pity that the city has never been able to occupy, and the Qingzhou army under the city has also been shot and fallen.

After noon, the Qingzhou army withdrew its troops in advance because of too many casualties.

The 30 ladders only had time to withdraw 10, and the Qingzhou army's explanation was that there were not many hoplites who were not injured, and they couldn't grab more ladders back.

The casualties of the Qingzhou Army in this battle reached 10,000, and many of the wounded soldiers who were brought back were inserted with feather arrows, and blood was still dripping.

However, if someone carefully selects the wounded soldiers and dead soldiers brought back by the Qingzhou army, they will find that the total number is less than 7,000, but there is a big gap with their attrition of tens of thousands of people.

And the central officers and soldiers at the head of the city looked at these Qingzhou troops who could act, and they all wanted to laugh, but in the end they were afraid of goofs, so they endured it alive.

Yu Ban sent people down to clean up the battlefield under the city, destroy all the undamaged ladders, and try to collect arrows without arrows, this time not for recycling, but to destroy the evidence.

The idea of the tiger-faced military division this time was really wonderful, he asked Lu Bu to collect the corpses of the dead officers and soldiers who rushed to the city when Cao Cao's army and Yuan Shao's army attacked the city two days ago.

Instead of throwing it down from the castle as usual, and deliberately slowing down the speed of the destruction of the ladder, as many Kwantung coalition troops as possible rushed up to the castle and died at the castle.

When the battlefield was cleaned at night, a lot of corpses were thrown from the city, and nearly 3,000 corpses were accumulated.

After the Qingzhou army rushed to the city, the drama that had been arranged began to be staged, and the Qingzhou officers and soldiers took off their uniforms, went down from the inside of the city wall, and stayed in the city.

Many of the officers among them are simply graduates of the Shaling Military Academy.

The central army at the head of the city put the uniforms taken off by the Qingzhou Army on the corpses of the soldiers of the Kwantung Coalition Army, and then added some knife and arrow wounds to the corpses, and then threw them down the city.

In this way, the Qingzhou Army, which had 6,000 dragons and tigers, entered the Tiger Prison Pass and transferred to the sequence of the Central Army.

What was thrown down was only 3,000 corpses pretended to be by the Kwantung Coalition Army, plus more than 4,000 Qingzhou troops lying under the city who pretended to be dead and wounded, which constituted 10,000 casualties that were fake and genuine.

The tactics of the Tiger-faced Army Division, "Li Dai Taozhuang", and "Concealing the Sky and Crossing the Sea" not only completed the difficult problem of the Qingzhou Army's attack on the Tiger Pass, but also successfully replenished the 6,000 elite new troops for the Tiger Pass.

No wonder Lu Bu attaches so much importance to him and entrusts him with important tasks, of course, thanks to the officers and soldiers of the Qingzhou Army, who are all excellent actors.
