He had just breathed a sigh of relief from the earth-shattering shelling, but he was covered by sudden crossbow arrows, and many soldiers of the Cao army fell to the ground one after another, caught off guard.

The officers of the Cao army shouted desperately, struck their helmets with their weapons, and kicked their buttocks, so that some of the Cao army mechanically raised their crossbows and shot at the cavalry of the Central Army who rushed up.

But this moment of hesitation was enough to make many of the Central Army cavalry rush to their front.

At a distance of thirty zhang, each cavalryman of the Central Army took out a grenade with a wooden handle, pulled the string together, counted silently together, and then threw it out fiercely.

Thousands of grenades burst above Cao Jun's head and in the crowd at the same time.

Although the Cao infantry was protected by armor, and even the crossbowmen were wearing chain mail, the fragments of the grenades could still partially penetrate the heavy armor, and more fragments were penetrated through the gaps.

Guo Jia was completely shocked by Zhao Yun's series of methods, as a military advisor in the era of cold weapons, he could never have imagined that the power of firearms was so huge.

Fortunately, as a brilliant man, his reflexes and adaptability were far beyond ordinary people, and he immediately ordered the cavalry to charge from the center, and the infantry to retreat from both flanks behind the cavalry.

At this time, the cavalry of the Central Army who rushed to the front had already rushed into the Cao army infantry, the halberd rose and fell, the Mo knife flew, and many Cao army infantry became the soul of the sword.

Fortunately, Cao's cavalry rushed up decisively and saved many of his infantry brothers.

The horn sounded, and the cavalry of the Central Army retreated from the left and right flanks in an orderly manner before their own camp.

Instead, there were five thousand black heavy armored cavalry in the middle of the road, and their subordinate war horses slowly pressed forward with neat broken steps.

Cao Zhang, who led the cavalry of the Cao Army to charge, saw the heavy armored cavalry of the Central Army appearing in the distance and was excited.

He raised the spear in his hand and waved the agreed signal, and the cavalry of the Cao army also changed formation.

The 5,000 tiger and leopard cavalry all rotated to the center and advanced slightly, while the rest of the cavalry followed closely on their flanks, forming a standard cone formation and attacking forward.

"Brothers, raise soldiers for a thousand days, use soldiers for a while, let Xiliang Tugou see the might of our tiger and leopard riding today! Charge! "Cao Zhang, who has long wanted to learn about the heavy armored cavalry of the Central Army, is already impatient.

He had already found that in the middle of the front row of the heavy armored cavalry of the Central Army, there was a white horse, on which was a general in silver helmet and silver armor, the protective surface of the wolf's helmet had long been lowered, and he was holding a bright silver spear.

According to intelligence, the generals of the Central Army in this dress include Lu Bu, Zhang Liao, Zhao Yun, Ma Chao, and Zhang Xiu, and the one in front of him is probably Zhao Yun, the commander of this heavily armored cavalry.

The victorious general Zhao Yun and Zhao Zilong can be regarded as prestigious, and he is a first-class general, and Cao Zhang is a martial idiot who likes to fight with these famous generals the most.

It's a pity that what disappointed him was that the first thing that greeted him was not the bow and crossbow of the Central Army, but the mortar attack that had greatly destroyed the fighting spirit and body of the Cao army's infantry just now.

He didn't notice that the light cavalry of the Central Army, which had withdrawn to his position, was lined up, but all the Central Army, including the heavy cavalry, was only moving forward slowly, rigidly controlling their speed.

Nearly 120 zhang of space was left in the cavalry array of the Central Army and the Cao Army, and the cavalry of the Central Army was waiting for this round of shelling.

Cannonballs rained down on the charging Cao army's cavalry formation, and the huge explosion and strong flash of light made the Cao army's war horse, which had never experienced all this, panic out of control.

The frightened horses fled with the knights on horseback, not to mention the blast waves and fragments of the explosion.

The ordinary cavalry of the Cao army was also light cavalry, all dressed in light armor, and the war horses under their crotches were unprotected, and even the protection of the infantry could not catch up, and they suffered heavy casualties.

The tiger and leopard rode at the front, and the protection was also the best, but it was the least affected by the shelling.

At the same time as the shelling stopped, the cavalry of the Central Army launched a charge like ghosts, a distance of 100 zhang, for the sprint at full horsepower, in an instant.

Many of the cavalry of the Cao Army were still in a state of blindfold under the shelling, and they were rushed to the front of the Central Army cavalry and shot down their horses.

And in the center of the battle array, there were two heavy armored cavalry that charged head-to-head, the wolf of the broken army rode against the tiger and leopard, and Zhao Yun rode against Cao Zhang.

The wolf cavalry selected from the hundreds of thousands of cavalry of the Central Army was far superior to the tiger and leopard cavalry in terms of strength, combat experience, and combat skills, not to mention the well-equipped horse lances and armor.

The war horses ridden by the broken army wolf are also the best of the best, all of them are high-headed horses in the Western Regions, with powerful martial arts, and their impact is much stronger than the war horses ridden by tigers and leopards.

The most important point is that they come here to recuperate, and they are fully clothed at the beginning of the war, and they are supported by horseshoes, unlike tigers and leopards who ride heavily armed for hundreds of miles.

And the horseshoe is a secret that Cao Jun has not discovered until now, but after Liao Hua surrendered, he still didn't know if it was a secret.

Anyway, whether it was the confrontation between knights and knights, or the collision between war horses and war horses, it all ended with the Central Army gaining the upper hand.

It was naturally Zhao Yun who took the lead in the charge, and he ignored the obstruction of Hao Zhao and Zhang Xiu, and personally went into battle and faced Cao Zhang head-on.

Although Cao Zhang is a number of generals in the Cao army and has strong martial arts, when he encounters Zhao Zilong, it is still not enough to see, and in just a dozen rounds, he was picked up by Zhao Yun and flew off his helmet, stabbed his arm, and fled.

Guo Jia saw that the cavalry of equal numbers were facing each other, and the Central Army still had the upper hand, so he was afraid that Cao Zhang would make any mistakes, so he decisively withdrew his troops.

He summoned all the troops in ambush, assembled them into defensive battle formations, alternated cover, and slowly retreated to the southeast.

Although the infantry and cavalry given by the Central Army to Cao's army were extremely inflicted, after all, Cao's army was many and elite, although they were defeated.

Under the command of Guo Jia, a complete formation could still be formed, and the infantry and cavalry covered each other and slowly retreated.

Zhao Yun did not chase after him, but collected his troops, cleaned up the battlefield, and treated the wounded.

Although with the help of mortars and grenades, the ambush of the Cao army was broken, effectively killing and wounding their living forces.

However, there were still many casualties in the process of close combat between the two sides, and the Central Army had a total of 5,000 casualties, but the Cao army that was eliminated was even more impressive.

Guo Jia's statistics are that the infantry suffered 20,000 casualties, and the cavalry casualties were about 10,000, of which the tiger and leopard cavalry suffered 3,000 casualties.

Ambushed the enemy with superior forces, but was severely damaged by the enemy, and this result made Guo Jia angry.

The huge casualties also made Guo Jia break the idea of continuing to attack Qingzhou, and instead waved his army south.

With the help of Liao Hua, Guo Jia consolidated and digested the occupied Langxie and Donghai counties, so that the entire Xuzhou fell into the hands of Cao Cao completely.
