At the same time that more than 100 large and small artillery pieces continued to fire in a row, the elite cavalry from a mile away rushed forward at the fastest speed in a fan-shaped direction.

Although these Tiger Zun cannon-level guns and those second generals have undergone a lot of potential digging and improvement, they are limited by the gunpowder level in this era, which is far from being comparable to the war period, if they want to hit a heavy bullet with a certain lethality to the armored target, they can only use six or seven heavy projectiles with a muzzle velocity and projectile similar to the catapult, not only can only shoot dozens of heavy projectiles at a time, but also because the muzzle velocity is similar to that of a bow and arrow, it is obviously ineffective at a distance close to one mile.

Therefore, the gunners, who had deduced and deduced all kinds of situations, did not expect to inflict heavy damage on the enemy cavalry at such a long distance by relying solely on artillery fire this time, but when the enemy cavalry approached a distance of about 200 paces, they covered and injured the opponent with a bow and arrow speed level of about one or two shotguns. The shotguns fired by 10,000 large and small artillery shells covered an area dozens of paces deep and more than 200 paces wide like black rain from the sky. Although soon after the enemy opened fire, these elite cavalrymen, who were experienced in fighting firearms, roughly judged that they should stop their horses and dodge backwards, more than two dozen horses were hit by these projectiles of bow-level energy. At a distance of about two hundred paces, the projectiles, which were incomparable in energy and speed with ordinary arquebus bullets, smashed out one or more large blood packets on those twenty or so horses, and only a few entered the flesh and opened their mouths to see blood. These horses were not as brave as the horsemen's own mounts, and many cowered after non-fatal wounds.

However, the more than 100 elite horsemen who had already made combat arrangements still did not waver in their previous determination in this situation, relying on their tough riding skills in the flank charge to desperately overdraw the potential of the horses, and slowing down the horses when they rushed to a distance of about 80 to 100 paces.

It was just a moment later that the second round of fire unfolded violently, and those who were able to ride were surprised that the guns could be reloaded again in such a quick time. This round of fierce attacks is still dominated by heavy shotguns with relatively high efficiency on the surface target.

Hundreds of light guns, two or three thousand six or seven two shotguns covered at the speed of bows and crossbows, at a distance of about eighty to a hundred paces, were not so easy to dodge, and most of the seventy or eighty horses rushing in front were covered by a heavy rain of bullets, and they quickly fell to death in a wail. There were only seven people on the horse, but only seven were shot in the head or lower leg, and their brains burst or their lower legs were broken on the spot. Through the blood of the horse's corpse or the blood of the people around him, it didn't seem to deter these armored men at all. Under the pressure of such a heavy battlefield, these people still relied on the body of their horses as shields to survive this round of the most intense artillery bombardment at close range, and then skillfully began to draw their bows and arrows.

All of this made many people, including Xiao Xuan, realize that this was probably the elite infiltrated by the Jiannu outside the Guan, and it could not be any bandit or horse thief from the Han land, or a domestic privateer of any force. Because it is impossible for the elite of the Han land in the Guannai to have such a strong sense of imperiency for war and battlefield psychological literacy.

When those heavy arrows were able to shoot through the simple shields of the young officers and soldiers in front of them, and shoot on the armor of the young soldiers in the front row, and even if they could not penetrate the shield armor, they could rely on the momentum of the heavy arrows to make the squatting young officers and soldiers follow, even many grassroots junior guards officers and soldiers with some brains realized that the mysterious cavalry on the opposite side was probably not from the pass.

The rain of arrows fired by more than seventy horsemen who had lost their horses was not dense, but the heavy arrows that flew over a distance of about eighty paces were barely out of the range of the crouching shield, even if they could not accurately hit the head. Under the protection of the shield, the young officers and soldiers in armor still began to suffer casualties one after another in front of the arrows through the shield.

Among the hundreds of archers, there were still about 300 brave teenagers who continued to fire arrows with specially made poisoned arrows at a distance of seventy or eighty paces, and in a very short period of time, thousands of specially made poisoned arrows were fired. However, in the face of loose targets from 100 meters away, very few hits. Only a dozen or so arrows were not dodged or parried, and they fell into the armor of the elite soldiers. As long as these arrows have ten times the lethal dose of special poisoned arrows in the grooves of these arrow clusters, they can kill the person who is shot in a very short time. But when none of these arrows shot through these elite soldiers with iron armor, it also demoralized the teenagers who fought back.

Immediately afterward, the strong bows with more than one stone and two fighting forces began to fight back with these poisonous arrows. Although these arrows were much lighter than the heavy arrows used by the elite soldiers outside the gate, and did not quite match the bow shape, the reflected bows and arrows were probably only about seven or eight buckets of strength, but in less than a minute, more than forty of the hundreds of poisoned arrows fired by the opponent hit the young officers and soldiers in the resistance, especially the people near the gunners.

Most of the poisoned arrows shot from a distance by the power of seven or eight buckets were not able to penetrate the armor selected from the imperial horse prison on the boys' bodies, but there were still some arrows that passed through the gaps between the pieces of armor and caused more than ten teenagers to be poisoned and died.

Under the cover of a continuous stream of accurate and deterrent heavy arrows and poisoned arrows, another group of elites who rushed from behind began to approach closer distances and prepare to attack. As the elite armored men under alternate cover approached a distance of about forty paces, more and more arrows began to shoot sideways, bringing more and more dead and wounded children.

For the first time, Xiao Xuan felt that when facing an unimaginable elite, the pressure on his own side with a twenty or thirty times superiority in strength was so great, especially when there was no shield car as a cover. What brings even more pressure is that I don't know what level of elite these people are in Houjin. If only about 20,000 people in armor in Houjin were of this level, then it would be an unimaginable conspiracy to enter the Central Plains until seventeen years later.

"Do you want to use the 'bottom of the box'?" At this time, a pro-soldier next to him also said a little critically.

Xiao Xuan hadn't lost his mind at this time, he dared to lead two or three thousand people to fight, of course, the trump card was not just a giant poisonous arrow, but the others who were not prepared until the last moment seemed to be absolutely not used lightly.

"Don't just yet, give the order for the gunmen to open fire as the enemy forces approach closer! The reloaded gunmen and firearms men prepare the whole army to retreat when they open fire! Lift the cannon and take it away! The general cannon is ready to explode and fire! Xiao Xuan finally ordered after thinking for a moment at this time.
