The umbrella that was opened in the military formation was called 'Tianluo', which was built on the basis of the Taiping umbrella, and Shangguan Luoyi improved it in combination with the principle of Xuanwu heavy armor, which did not only borrow its name, but borrowed from the tortoiseshell overlapping structure, and reduced the external impact layer by layer until the external force completely disappeared for effective defense.

The Luo umbrella is composed of several layers, the top layer is composed of independent armor, but it is not firmly installed, this is to have a certain resilience when the arrow hits, and the lower layer is the chain mail nested with iron rings, which forms a pull force on the arrows that are shot, and the bottom is the rough leather is also for cushioning and extension, and finally the umbrella surface is made of fine iron.

Such a large umbrella is very heavy, it is not easy to lift it, so it can only be inserted on the ground to be fixed, a Tianluo umbrella can provide protection for at least five soldiers, hundreds of large umbrellas can protect a phalanx, soldiers do not need to raise a shield to defend, and their hands can be freed to focus on holding a gun.

The rain of arrows of "Ding Ding Dong 、、、" continued to hit the Tianluo umbrella, and the soldiers who were still a little worried immediately settled down, because most of the arrow rain was isolated from the umbrella, even if there were a few that could penetrate, but because of the friction between its long arrow shaft and the umbrella surface, it was dragged down and fixed on the umbrella.

Yun Hao was not surprised by this result, although Beihun was good at arching horses, he was not born with divine power, and the projection was not a direct shot at close range, relying on the speed of the arrow falling to cause damage, even if it was an arrow made of the claws of the earth devouring beast, it would also weaken the power in front of this Tianluo umbrella, even if it penetrated the umbrella surface, the soldier still had heavy armor, and it was expected that a large-scale attrition could not be formed.

At this time, after the 'leopard riders' shot a rain of arrows, they immediately separated left and right and circled around the 'tiger riders', and they did not need to look at the damage caused by the rain of arrows, because past experience told them that nothing could not be destroyed by a rain of arrows, and they would never look back after releasing the arrows.

Sometimes extreme self-confidence is not necessarily a good thing, the 'leopard riders' in front of them disperse, and the fierce 'tiger riders' show their hideous fangs, and the horses form a huge cone, which is the most effective tactic for charging into battle.

With the smoke and dust raised through the leopard cavalry, what came into view was not what I had thought before, the scene of the Izumo army falling in a large area, but the army was neat and full of spears, waiting for the advance of the Northern Huns.

The third column of the Zhenbei Army was three sides

The strong archers and soldiers of the formation were staring at the Northern Hun cavalry rushing in the distance, while their officers were all facing the rear generals, and the officers of each team were waiting for the military division to give orders.

When the tiger rode a few miles away from the first phalanx, there was a sudden accident, and there were horses in the horse team who missed their front hooves one after another.

Ah Guda immediately had a bad premonition in his heart, and then he was on the high platform in the distance, and a yellow flag was waving.

"Full bow rapid fire! Don't leave an arrow behind! Shangguan Luoyi gave an order.

The generals in the archer phalanx immediately shouted: "Commander's order, full bow and rapid fire!" Don't leave an arrow behind! ”

In an instant, all the strong archers opened their bows and arrows, and quickly shot out arrows at an oblique angle to the sky, and a large rain of arrows poured down under black pressure, directly hitting the charging tiger horse.

The arrows of all the archers of the Zhenbei Army were inserted on the ground in front of them, which was to be able to quickly take arrows and shoot quickly, and with a round of arrows raining out, the Northern Hun cavalry also fell one after another.

Long before the rain of arrows arrived, Ah Guda had already drawn his scimitar and commanded: "Stretch out the leather shield!" ”

In order to increase their speed, the cavalry used not iron shields or wooden shields, but simple leather shields made of rough leather and wooden sticks, although they could play a certain protective role, but after all, they were still limited, so only by speeding up the impact could they reduce casualties.

But even if he didn't get an arrow, there would still be a lot of war horses that would be knocked down inexplicably, and Ah Guda also began to pay attention to the ground, and his eyes immediately widened at this look!!

It turned out that the withered yellow grass on the ground had been deliberately tied into a straw rope knot, which was the reason why the tiger rode a horse and stumbled, and this grass provided a natural camouflage for the knotted rope, which would not be noticeable unless you looked closely.

But at this time it was too late to say anything, so he could only continue to charge, and as the number of men and horses who stumbled and were hit by arrows increased, the cavalry in the rear also reached the expected speed in order to avoid it.

Yun Hao took the guards a few days ago, not hunting and playing on this grassland, but surveying the terrain, the soil layer of the grassland is loose and soft, and the marching route for the cavalry must choose the land with moderate softness and hardness, so as not to burden the horses.

Those Northern Hungarian scouts and horses back and forth to reconnoiter is to determine the route, the gap in the east stretches for hundreds of miles, if you can't determine the Northern Hun march route can not be defended at all, in the past, the North Hun only sent a small group of cavalry to raid, and now to attack on a large scale, you need to scout the cavalry to survey the terrain frequently, this is the judgment that Yun Hao reached, and it is also the reason why he chose to set up a formation here.

It is the most practical and least expensive way to deal with cavalry, although it cannot fully achieve the effect of containment, but as long as it can slow it down, it has achieved the set goal.

What the guards have to do every day is what Yun Hao calls the 'ground net' knotted grass ring, this grass is moderately soft and hard, the toughness and grip of the grass are also enough, and the knot ten grass rings are worth it as long as they can trip over a horse, so these guards are also extremely hard-working, and they can't beat tens of thousands of grass knots in a few days.

Now in the face of the greatly reduced power of the Northern Hun tiger and leopard cavalry, Zhang Beihai stood at the front of the team with a gun and said: "They are coming!" If we want to make great contributions, if we want to die, we will die vigorously, and as long as we resist the position, we can win! ”

As he spoke, the tiger cavalry had collided with the gun array, and the Zhangba spear played a huge role in the face of the impact of the cavalry, and the first batch of war horses were directly penetrated, and although the spear was on the ground, many of them were broken by the huge impact, and for a while, the roar of the war horse and the shouts of the soldiers resounded throughout this grassland.

If the tiger and leopard ride is a turbulent torrent, then the first phalanx led by Zhang Beihai is a stubborn rock in this turbulent river.

After encountering stubborn resistance, the tiger and leopard cavalry divided into two groups and continued to attack along the edge of the Zhenbei army's formation, but the speed advantage had been greatly reduced, and the edge of the inverted triangle army formation in addition to the tower shield, also stretched out the long knife of the horse, and did not have to wave it Just wait for the horse to pass through the formation to harvest countless horse legs.

The war horse charge one relies on speed and the other relies on concentration, but these two advantages have failed, and countless cavalry can only rush and kill indiscriminately in the gap between the military formations, but without the speed of the war horse, the scimitar in the hands of the Northern Hungarian cavalry is difficult to exert its lethality, especially in front of the heavy infantry regiment in Izumo.

The shouts of killing came and went, and the withered yellow grass was also stained red with blood, which shows its tragic degree, so this battle was called the 'Red Prairie Battle' by later generations.
