When the Turks attacked, they had already fought with the former army Xiaoguowei, fighting cavalry against cavalry, and the armor was mighty, colliding together, making a piercing and heavy tearing sound.

"Poof!"

These Turkic warriors, armed with long knives and spears, were extremely brave and skillful, so with the help of the impact of their horses, they had the advantage, and there were many of them, and 100,000 iron horsemen poured up, wave after wave, enough to crush all opponents.

Tu Wanxu was completely dumbfounded, but he was a royalist, more than ten years ago, when Yang Guang was still the king of Jin, he had already followed Yang Guang, so he was loyal, knowing that he could not retreat, he had to fight to the death, otherwise, the Praetorian Guards in the rear would probably suffer.

Because there are only 20,000 cavalry in the middle, left, and right armies, and more are infantry, on the grassland, fighting cavalry with infantry is simply looking for death.

War horses have an irreplaceable and important role in the ancient cold weapon war, because the speed and impact of the cavalry are difficult to compare with the infantry, if the two sides are equal, the cavalry side can maneuver to attack, using the rapid impact force, the infantry formation is scattered, washed down.

Tu Wanxu was anxious in his heart, and he had already let people release an emergency signal, and then ordered the three armies to fight to the death to support it, so as to leave time for His Majesty to retreat in the rear, otherwise, more than 100,000 Praetorian Guards may be wiped out here, and the Great Sui Emperor and the Minister of Civil and Military Affairs will also die here.

Sure enough, Yang Guang and the others saw the fierce battle several miles away in the back, and all of them changed color, and immediately knew that the situation was not good, so they turned around and withdrew.

However, Pei Ju, Yu Wenshu and other people persuaded that the left and right armies must be left to form a second round of defense line, so that the Chinese army can rush back to Yanmen Pass.

Yang Guang was so frightened that the six gods had no master, and immediately agreed to this arrangement, letting Laihu'er and Pei Renji take the left and right armies to resist the Turkic cavalry, at least for two or three hours.

"The last general commands!" Although Laihu'er and Pei Renji complained bitterly in their hearts, at this time, it was a good time to serve the country, and the iron-clad demeanor of the soldiers was manifested in this kind of crisis, where they could throw their heads and spill their blood.

After a few simple explanations, Yang Guang and Empress Xiao got into the carriage, some ministers who could ride horses got up, and those who could not ride horses also sat in other vehicles, and then under the escort of 30,000 Chinese army soldiers, they fled directly to Yanmen Pass in the southeast.

A few days ago, the route of Yang Guang and others was from Yanmen Pass, and then went northwest to Mayi, and then went north deep into the grassland, and then went all the way to the east to inspect several grasslands, so the location at this time, the distance from Mayi and Yanmen, has been almost far, for safety reasons, Yang Guang and the ministers have chosen Yanmen Pass insurance, compared to Mayi is an important town outside the pass, once surrounded by Turkic cavalry, it is difficult to fly, at least there are more than 40 small cities in Yanmen County, heavily defended, and the degree of security is higher.

In a moment, the Turkic army broke through the barrier of the former army of the Great Sui Dynasty, Xiaoguowei, and outflanked it from both flanks, after all, the number of people was twice as large as the previous army, so it could not be blocked all.

Suddenly, the Turkic knight team roared and rolled over like a tide, and the hooves of the wild horses exploded like muffled thunder, the blades and spears flashed, and the sound of killing shook the grassland, like a landslide and the ground cracked.

"Array!" Lai Hu'er is also a fierce general of the Great Sui, well-informed, and has been fighting horses all his life, and he is not frightened, and he ordered the left army to open the formation.

Seeing that Laihu'er was so calm, the fear in his heart was also reduced a lot, and he began to give orders.

"The pikemen and shield bearers are in front, the crossbowmen and archers are in the center, and the cavalry is on the two flanks—" Lai Hu'er roared loudly, and the irritability and fear of the three armies suddenly calmed down a lot.

When there was only one arrow and half on the ground, many knights hung up their long swords, took their bows one after another, and then the long arrows were wound, and then ten thousand arrows were fired in unison, and the rain of arrows poured out and shot at the opposite phalanx.

The shield bearers of the Sui army immediately raised their shields and tried their best to block the arrows for the phalanx, while the thousands of longbowmen behind also began to bend their bows and shoot diagonally into the air, drawing a forty-five-degree angle and falling towards the land of an arrow.

The Turkic cavalry, which was charging into battle, was inevitably attacked by arrows, and the people turned on their backs.

However, the speed of the cavalry team was very fast, and even if some comrades were shot, it did not affect their charging momentum at all, but their eyes became redder and murderous.

When fifty paces away from the Sui army's formation, the Hun knights had already collected their bows and arrows, and some knights held short spears in their hands, and with the strength of their arms and the inertia of their horses, they sent out a second wave of attacks, and threw them together, with great power, which could pierce people, nail them to the ground, or penetrate two or three armor soldiers.

This is the most simple and effective tactics of the Turkic cavalry, riding and shooting arrows, throwing short spears in unison, disrupting the opponent's position, making the enemy fearful, and then swinging their swords to slash head-on, driving straight in, as fast as thunder and lightning.

The Central Plains soldiers phalanx, few can live, unless the famous general leads the troops, a lot of preparations and formations in advance, in order to fight.

Lai Hu'er had followed Yang Su for a period of time, and he knew a lot about the fighting style of the infantry against the cavalry, so he was not flustered, and when he saw the cavalry rushing up, he immediately gave the order and set up a gun formation!

Boom!

Several rows of armor soldiers in front of them, holding spears, crouched on the ground one after another, holding an iron-headed spear up to a zhang long in their right hand, one end of the handle of the gun was heavily pressed against the ground, and the finger was pointed diagonally upwards at an angle of 35 degrees; Holding a small round shield in his left hand over his head, neck, and chest, covering vital parts, it looks like a forest of guns.

"Whoa—kill—"

When the Turkic iron cavalry arrived, they saw the dense spear edges, the cold light flickered, and they knew that they would die if they rushed up, but there was no turning back, because he could not slow down and stop, and the speed behind them remained the same, as long as they stopped a little, they would be squeezed to the ground by the iron cavalry behind them, and trampled to death.

There is no way back, only to move forward bravely, which is their pioneer mission.

Many knights were even picking up their speed, and then came to the front, ready to jump and rise, using the trampling of their falling horses to crush the Sui soldiers below.

At this moment, the crossbow operator in the middle, starting the crossbow machine, shot directly at close range, very accurate, poof, poof, shot knights and war horses, and just shot directly into the air, but it became an obstacle and a stumbling block.

But there was also no Turkic knight who was shot, let out a desperate roar, like a battle of trapped beasts, waved the big knife in his hand and slashed downward, and he had to pull a cushion on his back before he died.

"Click, click!"

"Puff puff puff—"

The spear pierced through the horses and human flesh, making a scream, and there were pieces of broken bones, and the soldiers on both sides were screaming, blood erupting, flesh and blood blurred, and it was unbearable to see.

"Da Sui boy, we are fighting for our family and country, as long as we hold for two hours, we will complete the task and protect Your Majesty to evacuate safely!" Lai Hu'er yelled, he was boosting morale, and he had to hold on for two hours, otherwise, the Great Sui Emperor and the ministers of civil and military affairs might all die on the grassland, the impact was too serious, and he had to fight to the death.
