Wang Han swallowed the noodles with great difficulty, and then said, "General Hui, we caught a few tongues, and the confessions are almost the same." The water used in this city on weekdays is drawn from the mountain spring and river outside the city. ”

Feng Yong guessed correctly, there was indeed no Longguan City built on the mountain, but its water source advantage was that there was enough water supply to the city whether it was in the east or west.

The enemy attacks from the east, it can take water from the west, and the enemy attacks from the west, it can take water from the east.

And whether the enemy came from the east or from the west, there was no way to send a large army around the castle to cut off the water source behind.

Therefore, at this time, Longguan can only be regarded as a trouble to get water, but there is no worry about water cut-off.

Hearing Wang Han finish talking about these situations, Zhao Guang was the most anxious, only to see him snort and finish the soup in the bowl, wipe his mouth, "Brother, let's attack the city directly." ”

"The longer we delay, the better it will be for Cao Thief. If it is really as the prime minister estimated, the reinforcements from Cao Thief Pass will arrive in a few days, and we will come in vain this time. ”

Feng Yong burped, nodded, and said, "Okay, then start attacking the city tomorrow." Ju Fu, Wang Han, each of you led fifty night hunters, with many poisonous arrows, and today you will go over the mountain to the east of Guancheng in advance, and stay at the place where Cao Thief usually takes water. ”

"As long as you see fireworks in the sky tomorrow, you can start to intercept and kill the Cao thieves who come to fetch water from the city or the mountains. Remember, you can't get tangled with them, just interfere with them and don't let them get water. ”

Since Feng Yong took charge of the military power of Yueshan, he has carefully formed a dark night battalion from the Nanxiang soldiers and the Yueshan soldiers with the elimination system.

This army is the guiding ideology for the training of special operations in later generations, and it is necessary to be proficient in many weapons of length and shortness, such as bows, crossbows, swords, knives, and spears.

Mountain climbing, obstacle climbing, wilderness survival, deep water swimming, precision throwing, intelligence gathering, camouflage, infiltration, lurking, tracking, barriers, capturing and more are all within the scope of training.

Of course, it's impossible to make each of them proficient in everything, but each of them must be proficient in at least a few things, and then form a squad to fight together.

This cooperation is based on strong organization and discipline, and communication between them is guaranteed by a certain literacy rate.

Finally, there are many veterans who have survived the battlefield to provide various battlefield situations for simulation.

The money and food smashed down were enough to build a team of 5,000 professional soldiers, and only then did one hundred and thirty-two qualified personnel be trained, known as night hunters.

Fighting in the mountains and forests, as long as they don't go to the army and attack secretly, it is an exaggeration to think that one is a hundred, but in the case of not being surrounded by the enemy, it is completely competent to take one as ten.

If there are no more than 3,000 Cao soldiers in the city, then the equipment used to draw water will not exceed the number of 300 people, and in the case of attacking the city by itself, there will be even fewer people sent out to fetch water in the city.

It is impossible to say that Pang will send a large army to protect the water source in advance without knowing that the Night Hunter is ambushing.

"Wang Ping, you will take 3,000 men tomorrow and guard the north to prevent the Cao thieves on Guanshan from rushing down the mountain."

"Zhang Wei, you start to reorganize the army from now on, and the siege of the city in the next two days will be up to you."

"Zhao Guangyang, the two of you will follow me tomorrow and listen to my orders at any time."

Feng Yong assigned tasks in the camp of Shuai, and Pang Hui also kept an eye on the movements of the Han army in the distance on the Guancheng.

I saw that after the Han army built the nest car, it did not stop, and continued to build siege equipment.

By the time the sun was about to set, the prototype of three stone-throwing carts could already be seen.

However, this time, the bearing capacity of Cao Jun in the city is much stronger.

Pang Hui still had the heart to point to the well and smiled at the soldiers around him, "This stone-throwing cart, the stones thrown by it, the farthest is only about a hundred steps, if you want to smash the city wall, you have to move the stone-throwing truck to within fifty steps." ”

"This distance is the most suitable for a bow and crossbow, is this not sure that it is coming to send you to death? What's more, the pass is narrow, and at most it can fit three stone-throwing trucks, so what's the use? ”

The crowd burst into laughter.

This Longguan was built on a mountain, and there was not much place in front of the pass, and no matter how many people there were, the Han army could only come up in batches to die.

Unless you consume the defenders with several times the number of lives in the castle, don't try to break this level.

But if they push the stone-throwing cart up again, they will simply block their own siege road.

And this stone-throwing car, unless it is a batch of throwing stones, otherwise Liao Liao a few, what is the obstacle to the city wall?

At that time, as long as the order is given, the bow and crossbow are fired in a volley, and the catapult will be useless.

Pang Hui finally put his mind at ease at this time, it seems that Feng Yong, although he has a literary name, is just a Confucian student, how can he be undefeated if he acts according to the military book so rigidly?

If he knew that this person was like this, why did he put so many antlers in front of the pass to reject the horse?

On the contrary, he blocked the road for his sneak attack on the Han camp.

When night fell, the Han army below lit the lights again, and the noise was still endless, and it seemed that the other party was going to build equipment overnight.

This makes Pang Hui hate it so much, this Shu captive, relying on a lot of people, it seems that he really doesn't take himself in his eyes!

In the early morning of the next day, I saw that a group of stone-throwing carts were placed under the gate.

"That rock-throwing cart, it doesn't seem to be the same as usual?"

Pang Hui stretched his neck, trying to see through the mist to see what was going on, but unfortunately, the Han army had already erected a high shield that made it difficult for people to see clearly.

"Are the rocks placed?"

Wen Shi shouted.

"Put it away."

The soldier in charge of the stone bomb replied loudly.

"Okay, ready! One, two, three, put! ”

A thigh-sized stone flew high and landed more than ten paces away from the city wall with the sound of the whirring wind.

Cao Jun, who had been holding his breath, burst out laughing.

This kind of stone-throwing cart is inevitably too weak, and it has not even touched the city wall, let alone destroyed it.

But Pang Hui was shocked, this stone-throwing cart was 200 steps away, and it could be thrown so far?

"The counterweight is too light, add another hundred catties."

Seeing this scene, Wen Shi hurriedly commanded the soldiers on the other side.

"Brother, this stone-throwing cart looks quite convenient, and it doesn't need to be pulled by a soldier."

Zhao Guang looked at the somewhat strange-shaped stone-throwing cart curiously and asked.

"You're talking about a human-powered rock-throwing truck, and I'm calling it a counterweight stone-throwing truck."

Feng Yong replied.

Stone-throwing trucks have been around for a long time, but they have always been launched by manpower.

That is, one end is loaded with stones, and the other end is tied with many ropes, and when it is launched, each person pulls a rope and uses force together to throw the stone out using the principle of a lever.

If you want to shoot far, the more people you use, and the bigger the catapult has to be.

But there is a contradiction here, with the ancient materials and techniques of production, the bigger the stone throwing car is, the faster the thing will break due to various reasons such as its own weight.

And the more people used, the lower the utilization rate of manpower, after all, there will always be a succession of force, and at the same time stand scattered, the direction of the force is not completely consistent, there will be a mutual cancellation effect.

Therefore, when the catapult exceeds a certain size, its power and range will decrease.

More importantly, with the development of city wall technology, the city has become more and more tall and strong, and this kind of siege equipment that has existed in ancient times has been difficult to directly cause serious damage to the city wall because it cannot keep up with the development of the times.

After all, due to the limited manpower, the maximum distance of the manpower stone throwing vehicle is generally less than 100 paces, while the range of the Han crossbow can reach 200 steps.

Coupled with the fact that it is bulky, easy to be damaged, inconvenient to move, and difficult to operate, the catapult can no longer serve the main task of siege.

It could be used to meet the enemy and destroy improvised wooden fortifications.

In Cao Cao's battle of Guandu, someone once transformed it into a mobile one to attack Yuan Shao's chariots and turrets made of wood.

The catapult returned to the peak of the battlefield, when it got the Song Dynasty.

The "return cannon" in the hands of the Mongols was to change manpower to counterweight, and the short arm of the lever was no longer pulled by manpower, but replaced with a heavy object.

There is no better understanding of such things as long-range strikes and non-contact warfare than Feng Yong in this era.

The catapult can be regarded as an ancient artillery unit, so its development process is clear to Feng Yong.

This kind of counterweight stone throwing car, as long as the design is reasonable, can throw more than 100 catties (Han Jin, 16 taels) of stones, and the distance can reach 300 steps.

Before the laughter of Cao Bing in the city stopped, the second stone flew over, and with a "bang", it smashed directly into the city wall, stirring up some dust.

Cao Bing laughed again, what threat can such a small stone pose to the city wall?

Pang Hui's expression was solemn, the power of the Shu thief's stone-throwing car was really greater than that of an ordinary stone-throwing vehicle.

The third stone soon reappeared, directly over the city walls, and struck the houses behind it.

Feng Yong raised his head and looked at the hanging basket on the roof of the nest car.

A red flag appeared on the nest car, and a flag was played.

"The distance is not enough, add fifty pounds of counterweight."

Although it was not hot, beads of sweat still appeared on Wenshi's forehead, although it had been tested before, it was the first time it was used in actual combat, and it was really much more complicated than when it was tested.

He secretly glanced at Feng Langjun, who was standing not far behind, but fortunately Feng Langjun didn't say anything.

The fourth stone smashed directly into the middle of the castle, and a passing signal finally appeared on the nest car.

"Okay, let's follow this counterweight."

Wen Shi shouted loudly, almost hoarse, "The captains of the various stone throwing trucks have come to collect the data. ”

"One prepares, put!"

The nest car gave a signal to the left.

"Adjust the direction!"

……

Zhao Guang and Yang Wan stood behind Feng Yong in a daze, looking at the person operating the stone-throwing truck shouting unintelligible terms, this was not the use of the stone-throwing truck they knew at all, and they felt unclear.

The Cao soldiers at the head of the city gradually couldn't laugh, no matter how stupid they were, watching one after another stones fly over their heads and fall into the city, they can also understand that the power of the stone throwing carts of the Han army on the opposite side should not be underestimated.

It's just that why do they only throw one stone at a time?

"Brother, let everyone smash it together!"

Zhao Guang stepped forward and said excitedly, "Such a good thing, it's useless to smash a stone one by one......"

He thought that what his brother made was just an ordinary stone throwing car, but he didn't expect it to be such a siege weapon.

"You know what? Look closely, it's called a test launch! In the future, if you lead troops into battle, and if you want to use this thing, you must know how to use it. ”

Feng Yong reprimanded.

……

"Test firing on the 10th is complete!"

After such a toss, the sun has reached mid-sky, and the fog on the mountain has all dispersed.

Wen Shi walked over and saluted Feng Yong, "Feng Langjun, it's ready." ”

Feng Yong nodded and ordered, "Let's start." ”

"No!"

Behind each stone thrower, something was covered with a woolen cloth, and a pile of sand was piled up around it.

A soldier lifted the woolen cloth, and underneath it was a jar wrapped with straw rope or hemp rope.

Cao Bing, who was on the gate, found that the things thrown by the Han army on the opposite side began to increase, and it was no longer a single stone, but a dense black shadow, like a giant locust flying overhead.

It's just that they are all a little puzzled, the Han army's stone-throwing cart is very powerful, but it is too badly thrown, and few of them hit the city wall, and most of them fell into the city.

There was a "bang", and something smashed diagonally on the arrow tower, making a breaking sound.

"What is this? How is it a pottery shard? ”

A soldier curiously picked up the fragments that fell on the city and looked at them, and said with a smile, "Isn't Shu Yu crazy?" Actually besieged the city with clay pots? ”

Pang Hui walked over, picked up a piece of pottery and looked at it, only to see that it was greasy and greasy, and it seemed to be used to hold oil.

Oil?

When Pang Hui thought of this, his heart suddenly burst out, and he shouted, "Not good! Quick, go down to the city and get water! ”

Unfortunately, his reaction was a little late.

Under the city, some of the soldiers who operated the stone-throwing truck soaked the tung oil with woolen cloth, then wrapped it on the stone, wrapped it tightly, put it in the leather pit of the stone-throwing truck, and lit it.

"Put!"

And the burning stones flew out and fell into the city.

With a "boom", the wooden houses that had long been stained with tung oil suddenly burst into flames, and the fire spread extremely fast, and in the blink of an eye, a small piece became a large area.

At this end, the soldier hurriedly shoveled up the sand, buried the leather nest that had just been burned, and then dug it out when the fire was extinguished.

The head of the city of Longguan constantly flies over the clay pots filled with tung oil, and occasionally there are burning stones, which fall into the city and constantly ignite fires everywhere.

The houses in Seki Castle are all made of wood, so naturally there are waterproof measures.

Cao Bing carried water and poured water on the burning house, but as soon as the water fell on it, the fire suddenly burst into flames, licking directly into his face, Cao Bing covered his face and screamed and retreated.

Cracking sound!

The huge tongue of fire jumped happily, as if thanking Cao Bing for the bucket of water he had sent.

Houses began to collapse and Mars rose into the sky.

From time to time, I saw that human fires rushed from the burning houses to the streets in the city, constantly calling for help and rolling.

"Quick! Hurry down and put out some of the fire! ”

Cao Bing obeyed the order and rushed down the city wall, but the fire on the street was so fierce that some of the people were forced to retreat.

Pang Hui's face turned pale, he really didn't expect that the other party was so vicious that he attacked the city, they were planning to burn all the people in the city alive!

It's just that where did they get so much oil?

Where is such a powerful stone thrower?

Why is the projectile so accurate?

Pang Hui's heart flashed with all kinds of doubts, and his heart burned like fire.

Cao Bing ran back and forth carrying water, trying to extinguish the fire, but somehow, the more he watered, the bigger the fire became.

The wooden houses were already prone to fire, and with the help of tung oil, it didn't take long for the fire to spread throughout the city.

However, the radius of Guancheng is only more than a mile in size, and the fire is so big that even Pang who is standing at the head of the city will be roasted with sweat like rain.

Feng Yong, who was standing at the gate, looked at the billowing black smoke rising from the city, and he didn't need to look up at the signal of the nest car, he already knew that the fire in the city was already unstoppable.

Fire attacks can only be launched at the right time and place.

Later generations have a very common question when discussing the Three Kingdoms: Why didn't Cao Cao use rockets when the grass boat borrowed arrows?

So many people debated from the perspective of romance, or historical facts, and even added their own ideas and so on.

In fact, the answer to this question is very simple, just one sentence is enough: because at that time there were no rockets at all, or rather, no one was aware of the large-scale use of rockets.
