Bai Liyan (Wei Xian) expected that the rebels must have loaded a large amount of calcium carbide and water in the armored carriage, and they just rushed to the city gate, and sprinkled water and set fire to the city gate.

"Bai He, order someone to prepare sand, if the rebels burn the door, immediately fill the dump bucket with sand and bury me, but anyone who approaches the city gate to pick up the soil, roll the wood and stones to fight back."

"No!"

The rebels intended to use a car to carry water and calcium carbide to burn the city gate suspension bridge, only to bury it once or twice with sand, after a long time, the rebels will definitely discover this law, it is necessary to organize people to come to dig the earth, re-ignite the calcium carbide.

Baihe was responsible for the defense of the city gate, so the stones thrown into the city by the rebels in the previous round were collected by Bailiyan, and most of them were concentrated on the city gate, just to bury the calcium carbide in the sand, and then take turns to smash them with stones to prevent the rebels from picking up the soil.

At the same time, Baili Yan transferred Su Hongxiao's cavalry battalion and 3,000 recruits to be responsible for the defense of the western section of the south city wall, Baili Yan led 3,000 recruits to sit in the eastern section of the south city wall, Lu Zhaoyu's arrow battalion bowmen released arrows in the center, Sikong Nanbaotao battalion was a reserve, on standby outside the safe area under the city [Note 1], and 30,000 people from the baggage battalion were responsible for replenishing and rushing the wounded to be sent to the hospital for treatment.

With the sound of a trumpet, the rebel crossbowmen stepped on the rhythm of the drum and began to move towards the city wall, the distance was quickly shortened from two hundred steps to one hundred and fifty steps, and when it was close to one hundred and twenty steps, Lu Zhao gave an order:

"All battalions listen to orders, archers open strings!"

The instantaneous rattling sound of strings came and went, the archers raised their heads to the sky at an angle of forty degrees, Lu Zhao gritted his teeth, his eyes were staring at him, and when the rebel crossbowmen entered the range of 100 steps, he immediately gave an order:

"Shoot the arrows!"

An ear-piercing roar swept through the sky, and thousands of arrows rushed straight to the rebels in the face of the scorching sun.

"Shoot the arrows!" Lu Zhao showed no mercy, and volleyed down two volleys in succession.

As the saying goes, there are only three arrows in front of the formation, which actually refers to the reality of the two armies attacking each other's infantry at the beginning of the confrontation between the two armies.

The infantry of the two sides fights, often starting to charge at a distance of 100 paces, and the crossbowmen are in front of the formation within 100 steps, firing thousands or even tens of thousands of arrows at multiple angles at the same time with direct shots, projectiles, and even side shots.

Even for well-trained veterans, two or three volleys can be fired at most at this distance, and then their own infantry is engaged in combat, and the crossbowmen retreat behind the infantry and continue to shoot arrows at the enemy's charging path, killing and wounding the enemy in the back of the enemy's charge, so as to cover the enemy charging infantry within 40 to 100 paces in front of their own formation.

Of course, a soldier can hold a shield and wear armor, and charge into battle with an overwhelming array of arrows, but it's not that way, it's not that simple at all.

The two armies fought in battle, and the survival rate of the first wave of shock could be described as slim, but all well-trained military formations, crossbowmen were all at the same time, from different directions, at the same time to launch a salvo to cover a local target.

It can be imagined that within three arrows, each array is 30,000 arrows at the same time to cover a charging route, and three arrows are 90,000 arrows.

The first wave of impact had to be at least seven or eight thousand or even tens of thousands of elites, and as a result, 90,000 arrow clusters were encountered, even if 90,000 arrow clusters could only kill and injure 35,000 people in the end, this is not a small casualty ratio.

In addition to the crossbowmen on both sides in front of the formation, there are also archers behind the formation, especially behind the long-pole weapon infantry formation, constantly throwing arrows in front of the formation, so the arrow clusters will rain non-stop like a torrential rain.

Unless you form a tortoiseshell formation, like the Romans, or if you are technologically and materially advanced enough to equip a large number of heavy infantry, and you have to be covered with plate armor from top to bottom, even if you are shot as a hedgehog, an arrow in the leg can trample you to death with a step on the back.

So in the face of thousands of arrows like raindrops, there is no power to parry.

Unless he is a fierce man like the Three Kingdoms Dianwei, he wears two sets of black iron armor inside and outside, and a pair of black iron armor is tied to the shield, and he leads people to rush hard against the enemy's fierce wind and arrows, and in the end, even if he is shot into a hedgehog, he is safe and sound.

However, there are only a few strong people like Dian Wei, for ordinary people, it is enough to wear one set of Xuantie armor, three sets of Xuantie armor, how can it be one hundred and forty or fifty pounds outward, no one can carry more than sixty kilograms of things on their backs, close the weapon helmet, etc., let alone charge into battle with one hundred and sixty or seventy pounds

The so-called "no more than three arrows" is actually hearsay.

At this time, Lu Zhao had already released three salvos, and when the rebel crossbowmen attacked within the firing range at the fastest speed, they quickly adjusted their posture and immediately began to return fire.

Bailiyan's strategy was that the infantry army continued to retreat in the bunker fortifications, and after Lu Zhao led the crossbowmen to fire a volley, the rebel archers did not return fire when they approached the city, and the archers of the Xian army were all equipped with a shield, and they all squatted down with a shield on their heads, and no one should rise to the top.

First of all, it is not clear when the rebels will attack the city, the rebels must use long-range weapons and hands to carry out the maximum damage to the defenders of the city wall, and the area of the city wall passage is limited, which means that the total area is a certain situation, and the number of crossbowmen placed on the city wall is limited.

The rebels are two groups of crossbowmen, each with 6,000 people, which covers a large degree of freedom and has a high density of crossbowmen.

The second is the lack of arrows in Guangxin. Don't look at an arrow cluster is very simple, in fact, the arrow shaft is a kind of primitive woodworking machine rolling planing process, subject to the current technical constraints, this kind of woodworking extremely production efficiency is not too high, Guangxin has been busy with weapons and armor for so many years, the reserve of arrow clusters is seriously insufficient. And it's still a defensive city, and you can't pick it up after the arrow is shot, so there's no way to recover it.

Lu Zhao's archers squatted on the ground with wooden shields on their heads, nine people in a group, tightly put together a large surface, arrows were like nails, they fell on the shields, some shot the bunker fortifications and the sand bags stood there, and some lost over the city wall and fell into the city.

The power of the giant arrows and flying stones was undoubtedly highlighted at this moment, and the dense crowd at the head of the city gave a great impact on the bomb, and the flying stones were sparsely blooming everywhere, and the shield array of nine people overturned four or five groups, and the giant crossbow arrows and losses that followed followed had eyes like locusts, and they rushed to the soldiers who fell after being hit by the stones, and several people were killed in a blink of an eye.

It's not that the arrows have eyes, it's that the rebels' arrows are dense enough to cover a large area.

The rebels fired several volleys, and the ironclad carriage behind the formation broke away from the line under the wave of the leather whip, and came straight to the south gate drawbridge gate, at this time the rebel siege team was still motionless, and had no intention of attacking the city.

Previously, Bailiyan had foreseen that after the appearance of calcium carbide, it would inevitably rewrite the rules of war between the offensive and defensive sides.

Under normal circumstances, the siege of the city is carried out together with the battle of attacking the gate and climbing the wall, both using the rushing car and the attack hammer to destroy the city gate, and at the same time using the ladder car and the siege tower to transport soldiers to the city wall, and the chariot and nest car carry the bow and crossbow hand to push to the front of the city wall thirty steps, and release the arrow from a high position

In order to avoid huge casualties, the rebels usually burned the door with calcium carbide first, and the besieging army did not move, and the crossbowmen suppressed the defenders. Wait until the city gate is burned through, and then urge the besieging army to storm the city.

This has the advantage that the rebels can attack the city from the gate and the city wall at the same time, distracting the forces of the defending side and demoralizing the defenders.

If you just wait for the city gate to burn through, and want to whimsically attack the city from inside the city gate, this is a fool's dream.

Not to mention that once the defenders found out that the rebels did not intend to climb the wall, but entered directly through the city gate, they would mobilize crossbowmen and long-pole weapons to line up on both sides of the inner side of the city gate, and at this time how many people rushed in and how many people died.

Just believe in this big city, regardless of the quality or quantity, the defenders have a lot of soldiers, even if they enter from the city gate, they will soon be able to block you back, and the battle under the city gate, the besieging side will be more disadvantaged, and the casualties can only be more tragic.

Therefore, after the city gate was breached, the rebels landed in the city at the same time, leaving the defenders in the first place, which could not only disperse the strength of the defenders, but also deal a huge blow to the psychology and morale of the defenders.

Since the appearance of calcium carbide, the rebels' new siege methods have greatly accelerated the siege speed. The rebels had previously attacked a city with a population of 100,000, and under the absolute superiority of the army, even if it was stormed, it would take more than ten days, or even a month. Now it often takes three to five days to break through the city, and the casualties are greatly reduced.

Because the four gates were burned through at the same time, and the battle for the city walls was in a stalemate, it was inevitable that the rebels would enter the city through the gates.

The ironclad carriage galloped all the way, the smoke and dust rolled into the sky, and the thunder looked at the south gate at this time, and he felt puzzled, just now I saw the Xianjun release arrows, why did it stop at this time, and there was no movement at all?

While pondering, the ironclad carriage, under the cover of the rebel crossbowmen, made a ninety-degree turn to the left, and rushed sideways to the drawbridge door, and the iron carriage opened an iron gate to the side of the drawbridge.

On the iron gate, stretch out a long and half-long, wide iron plate, the iron plate is shrunk in the iron carriage roof, after the car stops steadily, it is pushed out by manpower just against the city gate or jumping bridge, forming an iron shed, under the iron shed supports two thigh-thick logs as support, no matter what is thrown on the city wall, the iron shed is indestructible.

At this time, the five wrestlers were wearing iron frame heavy armor and hiding under the iron shed, and quickly carried bag after bag of sacks from the carriage horse, along with a few buckets of water.

Bai He, who was guarding the gate section of the city, put a shield on his head at this time, jumped out of the female wall and peeked down, and found that the iron carriage was parked under the drawbridge gate, and a large iron plate stretched out, which just covered the rebels and horses under the iron plate, and could not see anything.

[Note 1] Projectile surface: The size of the area covered by physical attacks such as projectiles, fragments, arrows, etc., the larger the projectile surface, the higher the damage coverage rate, and the smaller it generally refers to. Theoretically, the human head or foot has the smallest bullet surface, but in most cases it can't be done, so lying down is the smallest choice when the surface is completely exposed and cannot be avoided and hidden.
