"Thieves are damn good, and they lack virtue enough. Come on, hit Ben with a stone! ”

"No!"

More than a dozen people lifted more than 10 catties and 20 catties of boulders and smashed them down, and they heard the sound of banging and smashing the pot, but they didn't hear anyone screaming.

On the contrary, as soon as the soldiers showed their heads, they were immediately shot down by the rebel marksmen outside the city, and the angry Bai He scolded.

"Damn it, put the oil on Ben!"

"Wait!"

Someone shouted at this time, Bai He's face sank and he was about to turn around and scold, but he saw that it was Bailiyan (Wei Xian):

"General, these thieves are so fucking treacherous, this iron carriage is invulnerable, and the rolling wood and stones are useless!"

"Don't you pour the oil pot if you don't use it, and don't use your brains, the rebels set fire to the city, and a pot of hot oil goes down, whether to kill the enemy or help the enemy!" Baili Yan scoffed.

Directly above the city gate is a fixed dump bucket oil pot, a pot of hot oil is less than two hundred catties, not to mention that the cost is not cheap, what can this pot be used for, not only can not burn the rebels below, if you put a fire again, do not immediately set the drawbridge door on fire, this is not really to add fuel to the fire.

"Wait, wait for the rebel wagons to withdraw, and then cover the earth and throw stones."

"The last general obeys!"

The rebels continued to pile up calcium carbide under the cover of iron sheds, along with wooden barrels filled with clean water and oil barrels. A layer of calcium carbide, a layer of water, a layer of oil, until the carriage is in the air, a hill with a height of more than one person and a length of one zhang and a width of half a zhang has been piled up under the suspension bridge door.

The five ironmen then quickly withdrew into the carriage, and pushed out a bucket from the car, opened the lid of the bucket, there were three water scoops in the bucket, the ironclad man poured water with the water scoop, the water splashed on the calcium carbide sack for a moment, a burst of black smoke straight out, and then quickly burst a spark splashed around, the flames quickly rose, the ironclad man was quick, the two of them lifted the bucket together, and completely splashed it on the calcium carbide sack, poof, a loud sound, and the calcium carbide burst open.

These five people are probably also engaged in such high-risk occupations, and they put away the iron plate in a hurry, and quickly drove the carriage to flee rampantly. At this time, the fire under the city gate rose rapidly, and the calcium carbide lit the bucket and oil barrel, and the water and oil accelerated the burning of the calcium carbide, so in the blink of an eye, the flames under the city gate were billowing poisonous smoke and choking people.

The Thunder Heavenly King was overjoyed when he saw this, and at this time he could already think of why the Xianjun army wanted to add a suspension bridge gate out of thin air, it turned out to be to delay the destruction of the city gate by calcium carbide.

"Hehe, Wei Xian'er, now it's up to you how you deal with it."

At this time, Qin Han said worriedly:

"Heavenly King, there are drawbridge doors in the four gates of Guangxin, if they are all consumed like this, I am afraid that our army will not have enough water and coal."

Thunder disagreed:

"The water-fired coal fire was so fierce that there were enough to burn the drawbridge. After the drawbridge was breached, the king ordered the dead men to drive an iron chariot to push water and coal under the city gates, and introduce fire into it. ”

Before the words fell, just when Thunder was smug, his face suddenly stiffened.

I saw that the army defending the city was facing an overwhelming rain of arrows, and I don't know what they did, the horizontal platform on the city gate suddenly opened, and a large pile of black and brown things fell on the raging fire like a crumble.

"Quick, close the tipping bucket and continue to fill the earth!" Bailiyan shouted, and there was an endless stream of soldiers behind him.

Shaoqing poured down another bucket of sand, dumping the soil several times in turn, and the flames that had just burned were quickly suppressed. Bai He was overjoyed when he saw this:

"The general is wonderful, this method is really good!"

"It's not time to be happy yet, go, let people go and carry the sand bags, and smash them down for Ben, the more the better."

"No, the last general will obey!"

The fire under the city was gradually extinguished under the burial of sand and sand bags, and when Thunder saw this scene, the frustration in his heart jumped more and more on his face, and the smug color behind the mask was suddenly swept away:

"How so!"

I saw that the Xian army continued to dump sand and soil from the platform at the head of the city, and the fire gradually extinguished, until finally, only black smoke was left and still struggling to swallow the clouds and spitt out the fog.

"Wei Xian!" Thunder gritted his teeth, his eyes were murderous, and he smashed his old fist on the wooden fence, his heart was full of anger and malice.

Qin Han was taken aback, he had heard that water and coal were invincible, and the Black Turban Army relied on this thing to fight all over the world.

"Heavenly King, it is not surprising that sand and gravel can extinguish fires."

"Then why didn't anyone in the world use this method to extinguish the fierce fire before!"

"This ......" Qin Han was dumbfounded.

At that time, everyone knew that using sand to cover the fire source with soil could extinguish the fire, but they only knew the surface, but did not know the reason.

The sand and soil covering fire extinguishing method, in most cases, is suitable for extinguishing the fire with scattered fire sources, and it is convenient to take local materials, through the dispersion and burial pressure of the fire source, to achieve the purpose of controlling the fire first, isolating part of the oxygen and combustibles, and gradually extinguishing the fire.

In the face of integrated fire, it is generally useless, because the speed and amount of earthwork of manual soil covering are not enough to completely bury the rapid spread and expansion of the fire, and at the same time, the complex chemical combustibles are not, which is enough to extinguish the fire with the soil covering method, so as to disperse the fire source and isolate the purpose of combustibles and combustibles.

Therefore, the Black Turban Army attacked the city before, and the defenders found that watering was useless, but instead fueled the fire, and also used the method of throwing sand and soil from the city to extinguish the fire, but the effect was very small, and the reason was that it was not reasonable and inefficient.

Baili Yan made a wooden platform for tipping buckets, piled up with hundreds of catties of sand and soil all down at once, and can be repeatedly filled with a large number of overlying soil, and at the same time the sack containing sand is directly put into the fire, not to mention the large amount of high efficiency, under the cover of a large amount of sand, quickly disengage from the air, and finally suffocate the flame, to achieve the purpose of extinguishing the fire.

As the minutes passed, the fires at the South, East, and West Gates were extinguished one after another, and the rebels fell into anxiety and uneasiness for a while.

"Heavenly King, whether to bombard the Xian army's overturned platform with a stone artillery truck to prevent the Xian army from covering the earth!" 10,000 Captains.

Thunder was stunned for a moment, came back to his senses, waved his hand, drew his sword, and pointed at the south gate:

"Let people pick up dirt and continue to burn the door."

"This ...... This will only increase the casualties of our army, and it will not be conducive to the siege of the city, whether the whole line will be pressed. ”

Thunder was furious and said:

"You can't resist the order!"

"No, the last will obey."

The commander of the army sent a heavily armored infantry army to attack the city gate drawbridge under the cover of boxcars, but the besieging army remained in place.

Seeing this scene, Bai Liyan sneered:

"Hmph, the thieves are just like that."

"What does the general mean?" Bai He asked.

"Rebel sieges have always put the cart before the horse, first breaking through the gates, and then attacking the city. Do you know why? ”

"Naturally, the fierce fire can break the gate first, and the rebels can directly attack the city from the four gates, and then supplement the city, which is very fast and convenient."

"This is one of them, and the second is that since the Black Turban rebels have taken down more than 600 large and small cities, many of which are fortified cities in the world, why the rebels are invincible in a few months, nothing more than relying on calcium carbide to surprise and catch the defenders off guard.

Moreover, with the use of calcium carbide to attack the gate, the rebels can easily break through the city, and their own soldiers often suffer very few casualties. On the contrary, the defenders were breached at the first time in the four city gates in the south, east and west, and their morale was greatly damaged, and even completely collapsed.

Therefore, before the rebels attacked the city, they never encountered real tough battles and strong enemies, and they all relied on calcium carbide to fight all over the world. Now that we have encountered our army, this method has failed, and the rebel soldiers have become unstable and unstable.

In other words, it was you, the siege of the city was smooth sailing, and suddenly encountered a head-on blow, what would you think. ”

"The general is saying that the rebels are not good at attacking the city at this time!"

"Exactly, the rebels relied on breaking through the city gate first, and then ascending the city, which had the advantage of first breaking the morale of the defending army, and then attacking the city on all fronts, which could often crush the defending army in an instant. Therefore, the rebels had never been prepared to attack the fortified city, and now they were suddenly asked to attack it with flesh and blood, and he could not be afraid. ”

The rebels had attacked the city all the way before, and they fought all the battles, because they broke down the door at the first time, destroying and disintegrating the will and morale of the defenders.

Imagine that the four gates of the city are pierced, the enemy soldiers continue to pour into the city, and the defenders are lacking in skills, not only to intercept the enemy troops who are pouring in from the four gates, but also to hold on to the four city walls, which is equivalent to the force being suddenly divided into eight, and there is also the problem of communication scheduling, the four gates are broken at the same time, and the defenders have only one general, and there is no time to react and transfer troops in time, how to have the determination and confidence to hold on.

Over time, in the minds of the rebels, besieging a city is an easier thing to do than fighting. Now suddenly back to the cruel reality, the rebel generals and soldiers at all levels are not mentally prepared.

Moreover, Guangxin is the second strongest city in Xianguo, and 100,000 people desperately besieged it with conventional tactics, with a death rate of at least more than half. And now that the strength of the city is equal to the besieging rebels, how can there be 100,000 people to attack 90,000 people to defend the city. Even if the Guangxin defenders are a rabble, they are not 90,000 pigs, and the rebels are attacking the city head-on, even if they fill it with people, they can't fill it.

In the face of such heavy casualties, the rebels could not be terrified.

When peeking at the enemy's situation, the rebels' stone artillery carts and bed crossbows adjusted their battle positions one after another, and a heavily armored army of more than 1,000 people pushed the boxcarts, passed through the gap between the rebels' bow and crossbow arrays, and quickly approached the city gate.

"Lu Zhao!"

"The end will be."

"The rebels are turning stone artillery trucks to attack the dumping platform, and the armored soldiers who come out of front of the enemy will come to break the door for digging up the earth, and quickly order the feather arrow battalion, and the general will shoot the rebel armored soldiers."

"The last general obeys!"

"Baihe!" Bailiyan said again.

"What does the general command?"

"When the enemy soldiers approach the drawbridge door to pick up the soil, let me use pine oil and wine cans to fire it, and roll wood and stones to attack it, and never let it peel off the soil."

"No!"

The main force of the rebel siege was still unmoving, and the ironclad men broke away from the main formation alone, pushing the boxcart under the cover of the crossbowmen to quickly approach, and quickly adjusted the position of the long-range weapons, with the intention of destroying the dump platform, tearing away the covering, and continuing to set fire to the door.

At the same time, the situation at the east gate and the west gate was quite equal, and the rebels first failed to set fire to the fire with iron carriages, and then transferred heavy armor soldiers and boxcars to forcibly remove the covering soil and continue to set fire.

Compared with attacking the city head-on, if it can be completely broken at the cost of hundreds of people or thousands of people, it is still more cost-effective than killing and wounding tens of thousands of people.

The so-called boxcar is a kind of defensive mobile vehicle that is covered with wooden planks covered with cooked cowhide, or copper shield and iron shield, with a height of more than one person and more than a dozen people inside. These vehicles are propelled by the guards in the hiding vehicles to avoid enemy arrows and rolling logs. It can also be converted into a boxcar with a tipping bucket on top to fill the trench.

The ironclad soldiers of the Black Turban Army connected the boxcars end to end, like a section of train wagons, head on tail, tail on tail, one after another, forming six columns, closely connected, with a length of more than sixty steps. The soldiers only need to rush through the forty-pace-covered area of the bow and crossbow, and can quickly attack the city with the boxcar as a passage.

Bai Liyan was also taken aback, this was the first time he had seen or heard of the boxcar, and the boxcar could still be used in this way. This is equivalent to using boxcars to form a mobile tortoiseshell array, which can be used as a road to transport troops and quickly transport siege soldiers under the city walls.

If the gates were breached, the rebels could have used this method to quickly build a relatively safe passage outside the city and quickly bring in troops into the city.
