With the battle between Ma Tengjun and Han Sui's army with nearly 10,000 cavalry, it was inevitable that there would be a battlefield of people and horses fighting outside Yunyang County.

Ma Chao, Ma Dai, Pang De, Ma Xiu, Ma Tie and other young generals in Ma Teng's army, plus Cheng Yi, Ma Wan, and the three candidates, each led a group of soldiers and horses to rush and kill on the chaotic battlefield, just like eight sharp blades from time to time stabbing the Han Sui army in front of them to the back of the horse.

The form of victory and defeat on the frontal battlefield is obviously somewhat biased towards Ma Tengjun's side.

Ma Teng, who was standing on the city wall of Yunyang County, was quite satisfied with the situation outside, and then looked in the direction of the other side of the battlefield ahead.

There is also an army over there that can really decide the outcome of this battle, and it is also about to join the battle.

Although Ma Tengjun and Han Suijun seem to be killing fiercely outside Yunyang County, in fact, the troops invested by both sides are still reserved.

Ma Teng's side probably invested seven or eight thousand troops, including nearly four thousand cavalry from Cheng Yi, Ma Play, and candidates, and Han Sui's side also roughly invested about eight thousand troops, but still left half of the troops in the rear.

Of course, the two sides have invested so many troops, and the total is actually nearly 20,000, and it is also a bit boundless to spread out like this, which is enough for the cavalry to charge and run for a while.

Therefore, although there are brave generals such as Ma Chao and Pang De in Ma Teng's army who rushed to kill on the battlefield, they still couldn't completely decide the outcome of this battle for a while, after all, Yan Xing, Li Kan, Cheng Yin and other generals in Han Sui's army were also fighting bravely to help Han Sui's army save some of the situation.

It is still difficult to say the final result of such a battle situation, and maybe it can also make Han Suijun turn the tables.

Therefore, at this time, if a force can suddenly raid the rear soldiers and horses that have not been used by Han Sui's army, and completely disrupt the rear army of Han Sui's army, it will inevitably make the cavalry of Han Sui's army on the front battlefield lose their fighting spirit, which will lead to the overall collapse of Han Sui's army.

And this key force is naturally the nearly 6,000 heavy armored cavalry led by Zhang Xiu.

Now Zhang Xiu has gone out from the gate on the other side of Yunyang County with 6,000 heavily armored cavalry, preparing to bypass the frontal battlefield in front of him and directly attack the part of Han Sui's unmoved troops and horses.

The movement on the frontal battlefield also concealed the movement of the heavy armored cavalry led by Zhang Xiu, and now only Ma Teng knows the direction in which the heavy armored cavalry led by Zhang Xiu will appear.

In this way, after the frontal battlefield lasted for nearly half an hour, the heavy armored cavalry led by Zhang Xiu suddenly appeared on the side of the battlefield, and then like a rhinoceros beast, it rushed straight to the rear military formation of Han Sui's army.

Zhang Xiu took the lead with a lance, and behind him were more than 20 flag-bearers carrying the flag of the word "Zhang", also holding a lance, closely following behind Zhang Xiu.

When cavalry fights, naturally you can't use that kind of towering long pole to generalize the flag, so that with the galloping of the war horse, it is easy to break the flagpole.

Therefore, the cavalry's general flag is generally a double-pole flag tied to the back, which looks like a small flag on the back of the Japanese people when they fight, and it is also somewhat like the colorful flag behind the military generals in Peking Opera.

They can become the weather vane of other heavy armored cavalry in the rear, where they rush, the heavy armored cavalry in the rear will also charge with them, so most of these flag officers carrying the general flag are also selected masters in the army, and some people's martial arts are not even inferior to ordinary generals.

In addition, Hu Che'er, Wei Xu, Song Xian, and Hou Cheng are also standing in front of a team of heavy armored cavalry, they will be the sharp blade of the heavy armored cavalry charge, and will become the forerunner of the rear cavalry, and can guide the heavy armored cavalry to charge into battle after the heavy cavalry enters the enemy formation.

Therefore, the sudden appearance of these 6,000 heavy armored cavalry was completely unexpected by Han Suijun.

Under the command of Zhang Xiu, the heavy armored cavalry took advantage of the edge of the chaotic battlefield in front of them as a cover, broke through the battlefield in front of them on a rampage, and went straight to the direction of the rear army formation of Han Sui's army.

At this time, Han Sui also discovered the existence of this heavy armored cavalry, but everything seemed to be a little too late.

Han Sui could only command the archers to shoot a rain of arrows at them, and then commanded the reserve troops to prepare for the battle, at this time Han Sui could not directly lead the troops to dodge, which would only lead to the collapse of his rear army, and would make the soldiers and horses participating in the battle in front lose their fighting spirit, thus causing the whole army to be defeated like a chain reaction.

Only by resisting the charge of this heavy cavalry can we find another opportunity to withdraw the cavalry that was caught in the melee on the battlefield in front, so as to guide the whole army to withdraw from the battlefield in an orderly manner.

But the charge of a heavily armored cavalry could not be easily stopped.

What's more, although Zhang Xiu's martial arts cannot be included in the ranks of first-class and super, it is at least second-rate strength, coupled with the help of Hu Che'er, Wei Xu, Song Xian, Hou Cheng and nearly 6,000 heavy armored cavalry, it is enough to impact the military formation that has little defense in the rear of Han Sui.

The heavy cavalry did not care about the feathered arrows falling from the air, and under the protection of their helmets and iron-inlaid armor, the feathered arrows would only jump or splash away from the iron sheet if they landed, and rarely really hurt them.

Even the war horses under their crotches are also covered with iron armor, although this increases the weight pressure of the war horses, but also makes the war horses increase the artificial hard skin, as if the war horses have also turned into terrifying monsters.

The heavy armored cavalry soon rushed to the front of the rear military formation of Han Sui's army, like an iron piece crashing into tofu, and directly rushed into Han Sui's military formation, and the cavalry and infantry of Han Sui's army in front of them involuntarily retreated to the surroundings like splashing bean flowers.

This is not at all a manpower can be contended, this kind of heavy cavalry with the help of war horse charging tactics, do not need to use any spear skills, knife skills, as long as the lance gun in the hand is straight forward, you can make the opponent who dares to block in front of you are pierced into a sugar gourd.

As for the opponent's counterattack, there is no need to be afraid at all, ordinary lance stabbing and long knife slashing may not be able to penetrate the iron armor they wear.

What's more, the heavy armored cavalry led by Zhang Xiu also had nearly 6,000 numbers, so after the heavy armored cavalry crashed into Han Sui's rear military formation, the remaining Han Sui army of about 7 or 8,000 on this side did not have an advantage in numbers, so naturally there was no way to make an effective counterbalance.

Almost in a short period of time, Han Sui's army left in the rear to suppress the formation was completely defeated by the heavy cavalry, and Hu Che'er, Wei Xu, Song Xian, and Hou Cheng also led a team of heavy cavalry to tear apart the various gathering points of Han Sui's army, so that Han Sui's army had no way to assemble and counterattack.

Han Sui had no choice but to launch the order to retreat.

Immediately, Han Sui's army began to retreat, and the cavalry of Han Sui's army in the melee in front also sought an opportunity to get out of the battle, and tried to turn their horses' heads and retreat backwards.

However, in such a battle situation, except for a few cavalry of the Han Sui army under the command of Yan Xing, Li Kan, Cheng Yin and other generals of the Han Sui army, which could maintain an overall retreat of a certain scale, most of the cavalry of the Han Sui army were actually somewhat defeated.

As a result, the melee that was originally a confrontation between each other suddenly turned into a pursuit war between one side and the other, and Han Suijun had no heart to resist at all, but just wanted to get out of the battlefield as soon as possible and escape for their lives as soon as possible.

However, Ma Tengjun did not mean to let go of Han Sui's army, and the cavalry teams also followed Han Sui's defeated army closely to catch up......
