Xianbei people, who had never seen the power of gunpowder and detonators, suddenly tasted the taste of mortars, and how strong the shock was to them, one can imagine!

The loud sound of the cannonball's explosion, the rising smoke, the dazzling bright light, and the terrifying killing effect made them think that the Han army had mastered a terrible spell, which was regarded as a miracle!

And how can people compete with miracles, all Xianbei people have a strong fear in their hearts!

And Pei Yuanshao was naturally not surprised, he looked at the Xianbei cavalry who were still charging in inertia, and continued to give the order in a loud voice, "Reduce the distance by twenty zhang, fire three rapid shots, and then clean up the gun chamber." ”

Because the mortars of the Central Army are still using black powder, although they have been improved many times, there will still be residues of powder, and the chamber must be cleaned in time to avoid accidents.

Fortunately, the shells used in mortars have primitive shells, unlike ancient artillery shells, which directly fill the chamber with gunpowder.

There was another more dense and rapid "bang" and "bang" sound, and ninety shells rained down on the Xianbei army.

By this time, the Xianbei people already knew to dodge these shells, but they did not judge the landing point by the sound, but only urged the horses to flee as much as possible.

At such a close distance, by the time they heard the sound and saw the shells, it was too late.

The charge of 100,000 people, the dense and outrageous formation, finally caused a disaster.

In the frontal direction of the artillery position, at a distance of 180 zhang to 250 zhang, 90 shells fell one after another, but this rain was a bit heavy, and this rain was also a little painful!

The front, which was two or three miles wide and one mile deep, was covered with shells.

In this range, tens of thousands of Xianbei cavalry were killed and wounded, and their broken bodies and huge craters could be seen everywhere.

The entire battlefield was filled with thick gunsmoke, and all the Xianbei cavalry fell into chaos.

The Xianbei cavalry, whose wings were not shelled, were still charging by inertia, while the cavalry in the middle began to desperately beat their horses and flee back, where did they dare to charge forward?

Because the shelling was launched at the farthest range, there was no way to shoot in depth at the enemy who turned and fled.

The Central Army only used primitive mortars, which were only in the beginning of their form, and could not be as portable and flexible as the infantry mortars of later generations.

They had to build a level firing position, and the disassembly and assembly of the mortar was very cumbersome, and the most important thing was that the barrel life was extremely low, probably only firing about 50 shells.

Therefore, most of the wooden boxes brought by Pei Yuanshao were filled with barrels and shells.

Seeing that the enemy had fallen into chaos, Zhao Yun immediately ordered the whole army to attack, and he sent people to protect the artillery regiment.

Yes, Pei Yuanshao brought a complete artillery regiment, although there were only thirty mortars, and only five gunners were needed for each gun.

However, they are equipped with several times as many logistics personnel and the same number of engineers, as well as their own guard units.

The Han cavalry attacked from the left and right flanks, both bypassing the chaotic front, leaving the front to the two heavily armored cavalry regiments of the heavy brigade.

Taking advantage of his illness to kill him is the only rule that the Han army has always respected!

The beggar and a group of high-ranking nobles who were completely beaten by the two rounds of artillery bombardment of the Han army did not sober up a little until the cavalry on both flanks of the Han army broke through the interception of the troops on both wings of the Xianbei people and rushed straight to the main formation.

Seeing that the cavalry of the Han army was more brave than his own Xianbei iron cavalry, the crossbows were extremely sharp when they clashed on the horses.

The Xiongnu servant army entered the Xianbei army, and there was a feeling that the tiger had entered the flock.

And the most terrifying thing is the steel monsters that crushed from the front, and the knights on the horses are tightly wrapped from head to toe in heavy armor.

If the arrow is shot, it will only bounce off, and even if the saber is slashed, it cannot be destroyed, leaving only a white mark.

And how could the large spears in the hands of these Han army heavy knights (they didn't know the horse lance) still be used as knives?

Even if the Xianbei people were elite, they were light cavalry, and they were broken by the heavy armored cavalry of the Han army.

What's more, many frontal Xianbei people were still deeply shocked by the shelling and had not yet come to their senses.

However, the beggar is also a person who makes a decision on the spot, since he is at a disadvantage, then he should not continue to entangle, temporarily avoid the edge, and fight again in the future, which is a rational choice.

So he ordered to blow the horn of withdrawal, preparing to withdraw the army for the time being, and compete with the Han army again in the coming day.

However, he overlooked the fact that his most elite army of 100,000 was entangled with the Han army.

Originally, they were worthy of a battle, but the sound of the horn of the withdrawal made these Xianbei soldiers think that their side was defeated, and they turned around and fled.

The grassland people are already good at saving their lives, especially those cannon fodder troops and slaves who have not yet appeared, and they are even more amnesty and flee.

Originally, the beggar neighbor who wanted to retreat in an orderly manner could not stop the rout of these cannon fodder with only the 10,000 royal court guards in his hands, but was coerced together by them.

And Zhao Yun keenly grasped this fighter, he ordered the whole army to pursue, and asked that regardless of the formation, what formation, as long as there is an enemy, chase and kill, without an order, must not stop the pursuit.

So the 80,000 Han cavalry drove nearly 200,000 Xianbei cavalry like driving sheep, scurrying all over the grassland.

The Han army was organized at the grass-roots level with squads, platoons, and companies as its basic level, and was very suitable for this kind of tactics of fighting separately.

And the Xianbei people are accustomed to obeying the commands of the pursuing centurions, thousand-commanders, and thousand-commanders, and once they lose their command, they are like headless flies.

Zhao Yun immediately discovered this problem, and he ordered the sharpshooters of each department to specialize in sniping the leaders of the Xianbei people.

For a time, the commander of the thousand, the commander of the ten thousand and the other Xiongnu nobles were shot and fell, and soon the Xianbei nobles discovered this phenomenon, and they took off their gorgeous robes and high-class armor in order to fool the past.

The Xianbei army as a whole still fled all the way north, and soon caught up with the old and weak women and children who had moved in advance, as well as those cattle and sheep.

Because the Han army was chasing closely behind, the Xianbei army did not dare to stop at all, let alone escape with their families.

They can only overtake the civilians and continue to flee north, taking care of nothing.

However, it was precisely because of the barriers of these civilians and the blocking of the road by cattle and sheep that the Xianbei leaders and high-level nobles such as Qifu Youlin, as well as their royal court guards, escaped smoothly.

Because more and more Han cavalry were blocked by these civilians, old and weak women and children, and according to the military regulations of the Central Army, they could not be killed.

The Xiongnu servant army has long copied the military discipline of the Central Army, and it is no longer as willful as before.

Zhao Yun could only order to stop the pursuit, instead collect the prisoners and count the spoils, and these old and weak women and children, except for the women and children of the right age to be taken away as slaves, the others were left to fend for themselves!

Cattle, sheep, horses and other livestock, as well as many nobles who could not take away their belongings, were all taken away by packing carts.
