Although the lethality of the bed crossbow is very large, but after all, it is not dense, it is difficult to cause large-scale damage to the rebels under the city, and the number of rebels who dodged the bed crossbow and crossbow archers is very large, they pounced on the Tongguan city in a slightly scattered formation, and immediately there were leaders at all levels to organize a formation, ready to return the color to the Tang army at the head of the city.

But now the initiative is still in the Tang army at the head of the city, Li Fu and Pang Zhong know that it is impossible to repel the attack of the rebels with a few rounds of crossbow shooting, and the shooting of arrows is the most lethal to deal with the rebels besieging the city.

Therefore, after seeing the rebels enter the range of bows and arrows, the order to shoot bows and arrows was immediately given.

After Li Fu and Pang Zhong's orders were issued, at the east gate and the south gate, about 300 sergeants from each stepped forward, drew their bows in their hands, and pointed to the sky, almost the same height. In the frightening sound of breaking the sky, a dense pile of "flying locusts" appeared in the sky, and after flying in the upward direction for a while, they slowly turned downwards and fell towards the rebel display that poured up like a tide.

After firing a round of arrows, the first 300 or so sergeants immediately retreated, and the other 300 or so sergeants waiting behind immediately stepped forward, drew the bows that had been prepared, and shot the arrows on the string with the greatest force as the sergeant in front of them just now, without even looking at how much damage the previous round of arrows had caused to the rebels.

After the shot, he immediately retreated, and the sergeant of the next round immediately stepped forward and shot the arrow in his hand.

After shooting the arrow, it takes a certain amount of time to draw the arrow and wind it up, so that the two or three teams take turns to shoot in such a row, which can fill the time of pulling the arrow and winding it, so as to achieve the maximum degree of intensive shooting. Arrows are fired continuously, repeatedly, inflicting maximum damage on the enemy. Whether it is in the attack and defense of the city, or when the two armies are facing each other, this method is generally adopted, and the commander can order the subsequent sergeants to adjust the shooting angle and shoot at the enemy from different directions according to the change of the enemy's situation.

The area in Tongguan City that can shoot effectively is not large, and it is impossible for thousands of sergeants to stand together and shoot!

The arrows fired in this rotation were only a short time, and when the first round of arrows fell on the rebels' heads, the next round of arrows also appeared above their heads, and if we were to judge the time, it would only be about ten seconds at most. Such a dense shooting will make the soldiers under the city unable to hide.

The height difference between the city and the city is destined to exist, and this kind of drop will cause such a situation, the arrows shot by the soldiers at the head of the city can fall on the heads of the siege soldiers under the city, but the arrows shot from the city to the city head may not necessarily fall on the heads of the soldiers on the city wall, and may not even be able to shoot on the city wall, that is, the range of the arrows shot by the soldiers at the head of the city must be farther than that of the city down, which is the principle of kinetic energy and potential energy, and there is no way to overcome it. This also allowed the Tang army at the head of the city to start shooting at the rebels first, and the lethality caused by this relatively high-density shooting was also quite large!

As the arrows fell, countless screams came out from the mouths of the rebels under the city, countless sergeants who were hit by arrows fell from their horses, or were shot under the city, some people were seriously injured, some even died on the spot, the shield in the hands of the sergeant was not very dense and could not effectively resist the shooting of the arrows, the rebel formation was in chaos, and some of the commanders of the captains, brigade commanders, and generals were also shot, and there was no way to command the sergeants to form a queue, and at this time, the arrows shot by the Tang army soldiers on the head of the city continued to fly intensively.

As the arrows of the Tang soldiers on the city continued to fall, the city quickly rushed down, and the rebels who were ready to fight back in the same way and find a way to enter the city fell one after another, and continuous screams sounded outside the narrow east and south gates of Tongguan City.

The lethality of the arrows with huge kinetic energy was still quite large, and many rebel sergeants fell to the ground quickly after being hit by arrows in important parts, and many fell to the ground with serious injuries and became the target of the next batch of arrows. Many of the soldiers preparing for the siege were covered with arrows, a bit like hedgehogs. The hedgehog-like sergeants almost all lost their lives.

After only a few rounds of arrows, countless corpses had been piled up in the undulating open space in front of the city, and many of the wounded and fallen sergeants were trampled under the feet of their follow-up companions, adding height to the piles of corpses, and the screams continued to become the accompaniment of the battle.

Even the screams are no longer as terrifying and terrifying as they were at the beginning.

Get used to listening!

Li Fude, who had gained the upper hand in the continuous battle, had never experienced the defeat of Lingbao and had never fought with the rebels at the head of Tongguan City, was full of excitement, and ordered the sergeants to shoot all the attacking rebels under the city.

Even he couldn't bear it himself, so he opened his bow and shot arrows, and shot all the arrows in the quiver on his body before stopping.

Li Fu's archery skills are quite good, and the twenty arrows in the quiver were actually shot by him at eighteen targets, and those who were shot were injured even if they were not killed. A rebel who commanded the charge was killed instantly by Liford's final arrow, drawing cheers from Liford's guards.

Leaford believed that if such an offensive had been maintained, it would have been impossible for the rebels to set foot in the city.

Pang Zhong, who defended the south of the city, was not as optimistic as Li Fu, but he had just experienced the fiasco of Lingbao, and the 100,000 horses he led were almost wiped out, and after fleeing back to Tongguan, there were only two or three thousand soldiers left around him, leaving a very big shadow in his heart.

Moreover, in the past six months, he has commanded countless defensive battles in the city, and he knows the cruelty of the offensive and defensive battles of Tongguan City.

Before the defeat of Lingbao, the troops in Tongguan City were sufficient, surpassing the rebels in number, and even the Hantong Pass City that highlighted the key pass of Tongguan City had nearly 20,000 soldiers and horses to defend, when the rebels attacked the city, the defending sergeants could rotate to fight at the head of the city, and the arrows should not be worried about not enough.

But now, there are only more than 2,000 soldiers at the head of Hantong Guancheng, and almost all of the rebels are in battle when they attack the city, and even the rotating sergeants are insufficient.

It can be said that there are not a lot of arrows stored in the city, and there may not be a shortage of them, but the physical strength of the sergeants will definitely be exhausted.

It is very physically demanding to open the bow and pull the string to shoot arrows, and the sergeants take turns to shoot, and they may be able to withstand more than ten or twenty times in a row, and there will be no exhaustion, but after a long time, there will definitely be a situation where they cannot pull the bow and shoot arrows far.

At that time, it was the time when the rebels began to storm the city on a large scale, and our army struggled to support it.

Danger will arise at that time, too!

Pang Zhong only hoped that the danger would come later.
