The Warriors of the Three Kingdoms

Xu Huang also answered, and was even more worried about Liu Zheng's previous words. The ten days were somewhat tight.

"Although it is said that there is no chance, it is not that there is no chance at all."

"Please tell me, my lord!"

"As you said just now, trebuchet!"

"The lord wants to use the trebuchet, but the height of the tower, we can't throw stones up with a normal trebuchet."

"And most importantly, we don't have trebuchets here!"

The trebuchet is not a siege hammer. It only needs a larger log. The trebuchet has some mechanical principles, and ordinary people really can't make it.

Only some masters who are proficient in woodworking, or people who have learned how to make bows and arrows, can make it.

And even if it is a simple trebuchet, if the power is not enough, the projected stones are too small, or the lethality is not enough, and it will not be able to cause too much damage to the tower at all.

In fact, trebuchets have appeared a long time ago. They were widely used on the battlefield as early as the Spring and Autumn Period and Warring States Period, but the trebuchets at this time were all human-powered trebuchets.

The principle used is extremely simple, that is, erect a triangular railing, and then place a crossbar in the middle, and on the other end of the crossbar, prevent ammunition that is about to be projected.

Then on the other side, use manpower to tie a few ropes, and when several people work together, the ammunition on the other side is thrown out.

Although such a catapult can also be used, it is not powerful enough after all, and its lethality is not enough to break through the city wall. At most, it will pose some threats to the defenders on the city and dare not come out to defend the city.

And it requires a lot of manpower.

And the trebuchet that Liu Zheng had in mind was the elastic trebuchet of later generations.

Compared with the human trebuchet, the power and lethality of this trebuchet is simply a leap in quality.Not a thing at all.

"If there is no trebuchet, we will build it! Ten days is enough for us."

"Building a trebuchet? We don't seem to know many people. I have seen it a few times, so I will take someone to build it!"

After Xu Huang received Liu Zheng's order, he directly wanted to solve Liu Zheng's problems and build the trebuchet by himself.

Liu Zheng didn't know at this time that the trebuchet Xu Huang was talking about and the trebuchet he had in mind were not the same thing, so he happily worked hard.

"Okay, anyway, ten days later, it will be the day to attack the city. In the past few days, we will build the trebuchet first!"

At the moment, Liu Zheng and Xu Huang ordered their soldiers to send hundreds of people to cut down trees in the woodland outside Xianglin City.

The main force continued to guard here to prevent the soldiers and horses in the city from leaving the city.

It seems to be a simple siege, but it left a haze of being besieged to the soldiers of Lin Yiguo in the city. This state will make the soldiers of Lin Yiguo more and more depressed.

In just one day, Liu Zheng had ordered people to cut down enough trees to make trebuchets more than enough.

Xu Huang took the lead in demonstrating the making of the trebuchet to Liu Zheng.

Chapter 286 Remodeling the Trebuchet

The trebuchet built by Xu Huang has not yet started to be completed. Just erecting the lever in the middle has aroused Liu Zheng's doubts.

"Wait, Xu Huang, how do you plan to build your trebuchet?"

When Liu Zheng saw that what Xu Huang made was different from what he thought, he immediately had some doubts.

When Xu Huang saw Liu Zheng asking, he was not confused, but immediately explained to Liu Zheng.

After making gestures with his hands to make a trebuchet, and roughly describing his thoughts, Liu Zheng understood Xu Huang's meaning.

But after Liu Zheng understood what Xu Huang said, he didn't stop Xu Huang, but changed his tone and said something to Xu Huang.

"So, Xu Huang, how about this? In order to build trebuchets as soon as possible, we two will lead some man-made trebuchets respectively. We will try when the time comes, who can build better and have more attack power, how about it?"

As soon as Liu Zheng spoke like this, Xu Huang was immediately interested, and he immediately showed a smile.

"Haha, my lord, I'm sure I'll win. You haven't even seen a trebuchet, have you? How could you possibly build a trebuchet?"

"That's not necessarily the case, I have my own way, do you dare to bet?"

"Okay, what's the bet?"

"Well, let's bet on the head of Fan Yi, the Prince of Linyi Kingdom. I won. Then I will lead the army to charge the siege of Linyi Kingdom. If you win, you will come. How about it!"

"Okay, everything is up to the lord!"

The trebuchet that Liu Zheng had in mind was an elastic trebuchet, which did not use manpower to pull, but used the principle of leverage to throw heavy objects.

The specific operation is actually very simple. It is to make a huge crossbow. The lever pulled by the bowstring is the central axis of the trebuchet, and the main lever is locked. Using the elasticity of the bowstring, the lever bounces back, and at the same time drives the ammunition at one end of the lever to fly out. .

This kind of power is much greater than that of a simple person.

The distance and power of the projectile have been doubled, and when used in siege battles, it can definitely increase the chances of breaking the city for these people under Liu Zheng's command.

After Liu Zheng made up his plan to make the trebuchet, he first drew a small sketch in his camp, and then made it according to his own sketch.

Although he doesn't know much about woodworking, it's not a big problem to make a simple ballista trebuchet. This kind of principle is found in the high school physics knowledge of later generations. The principle of bow and arrow shooting.

Put it together and do some simple renovations.

For a day, Liu Zheng was making his own sketches, and then continued to improve them, using the triangular structure for reinforcement and collecting the required materials.

For three whole days, Liu Zheng was preparing for the preparations, but he hadn't fully started to act yet.

On the other side, Xu Huang had built three trebuchets in three days.

And after preliminary tests, the range of these trebuchets has actually reached 150 steps.

Although the distance of 150 steps is not too far, some powerful archers can reach it with arrows, but the trebuchets cast huge boulders weighing hundreds of catties, and the lethality is not comparable to that of arrows.

If the arrow is a single-point damage, then the trebuchet is a group damage. If a hundred-jin-heavy boulder hits the tower, if the tower is not strong enough, it may be directly pierced by these boulders, and the tower will be destroyed. collapse.

The projectile distance of the trebuchet made by Xu Huang is not too far, but its lethality is still acceptable. It can project a boulder of about [-] jin, reach the tower, and can also cause certain damage to the tower.

On Liu Zheng's side, he didn't start production for three days in a row, but just analyzed the production process one by one.

In three days, Liu Zheng turned into a researcher and began to gradually improve the ballista catapult he designed by dividing the process. It is best to simplify each step so that everyone can participate directly.

Everyone has to make a component, and finally combine it to achieve the goal quickly.

On the fifth day, Xu Huang had already completed the manufacture of five trebuchets. The first day was spent on cutting down trees and collecting materials, and there was basically no production. In the next three days, the speed of one trebuchet was spent every day. On the fifth day of production, the speed has even been accelerated, and two frames have been completed.

Five trebuchets were completed, which was enough to deal with Xianglin City. He came to Liu Zheng's side and wanted to see the situation on Liu Zheng's side, but when he came to Liu Zheng's construction site, he looked at Liu Zheng. After the construction site was completely empty, he was also stunned.

"My lord, where is your trebuchet?"

Xu Huang glanced around the construction site and was still a little puzzled when he didn't see any trebuchets except for some materials.

"Ah, Xu Huang, it's you who came. I haven't started making my trebuchet yet."

"I haven't started to do it yet, my lord, you probably don't know what to do."

Xu Huang opened his eyes, it has been five days.If there is no further manufacture, there are five days left, and Liu Zheng may not have enough time here.

Moreover, Liu Zheng's idea was to break through Xianglin City within ten days. Now that five days have passed, there are at most five days left for Liu Zheng.

"Don't worry, my trebuchet can be made very quickly. It can be made in less than a day, and there will definitely be more than yours."

"My lord, I feel that you are lying to me, I don't believe it!"

"Hahaha, don't you believe me, then just wait and see, there are still three days left, and we will start the siege on the ninth day, we can't delay until the tenth day!"

In Liu Zheng's mind, he never thought of going to attack the city on the tenth day. If he waited for his trebuchet to be built, Liu Zheng would decide when to start attacking the city.

Now that five days have passed, his preparations are almost done. The materials and various parts have been produced, and the only thing left is assembly.

A day or two is enough for assembly.

On the sixth day, Liu Zheng stepped up to make materials again, and tried to assemble it by himself.

After confirming that there was no problem, on the seventh day, he began to move the left and right materials together, and assembled the trebuchet with all his strength.

On the eighth day, the materials for a total of twenty catapults were all assembled.

He was dragged outside Xianglin City by Liu Zheng and covered with trees to prevent being exposed to the eyes of the defenders of Xianglin City.

And Xu Huang also pulled out his trebuchet. When he saw Liu Zheng's twenty trebuchets, he froze in place in surprise.

"How is this possible? In three or three days, twenty trebuchets were built?"

Chapter 287 Gather the Manpower and Prepare to Siege the City

Xu Huang couldn't believe that Liu Zheng built twenty trebuchets in three days.

However, he clearly saw that Liu Zheng didn't do anything a few days ago, he didn't build any trebuchets at all, but in just a few days, he transformed twenty trebuchets out of thin air.

This made Xu Huang feel extremely surprised. He walked into Liu Zheng's trebuchets, lifted the branches covering them, and after taking a rough look at these trebuchets, he looked even more bewildered. .

Because the trebuchet made by Liu Zheng is very different from his.Whether it is the shape or the method of projection, they are almost completely different.

The trebuchet made by Xu Huang still looks like a trebuchet, but Liu Zheng's trebuchet really doesn't look like a trebuchet. Not only is the whole reminder not too big, but even the way of projecting needs to be relied on. Some bowstrings to guide.

Rather than talking about a trebuchet, it is more like a large crossbow.

Xu Huang looked here for a long time, frowned and carefully observed Liu Zheng's trebuchets. Then, with deep doubts in his eyes, he couldn't help asking Liu Zheng.

"My lord, are you sure that the thing you built is called a trebuchet? You didn't mean to make a bet with me to win me, and you deliberately made it to fool me, right?"

"What? Don't believe me?"

Liu Zheng turned his head and looked at Xu Huang. Although Xu Huang had doubts about his own things, Liu Zheng himself did not doubt anything. On the contrary, he was very confident in his trebuchet, and he would only It is stronger than those human trebuchets made by Xu Huang.

"It's not that I don't believe you, it's just that the thing you made doesn't look like a trebuchet at all. Can it really break the gate of Xianglin City by relying on it? If it can't be opened, we swore before The promise Fan Xiong made in front of him was a slap in the face."

Xu Huang was still worried about Liu Zheng's previous words.

But Liu Zheng was not worried at all, on the contrary he was very calm.

"Don't worry, with him, I am [-]% sure that I can break through the gate of Xianglin City!"

"If you don't believe it, you will know soon, you will lose the bet between us!"

Xu Huang looked at Liu Zheng's trebuchets suspiciously, but it's only the ninth day. Although the ten-day agreement has not yet been reached, Liu Zheng has already pulled out all the trebuchets. Start your siege today.

At this time, on the tower of Xianglin City, Fan Xiong, who has been patrolling the tower for the past few days, often appears here because of his worries.

At this meeting, Fan Xiong, seeing Liu Zhengjun who was from outside the city, began to gather gradually, and seemed to have a plan to attack again. The worry and fear he had been worrying for the past few days finally began to become more nervous.

He hurriedly walked around the battlements to observe the changes on Liu Zheng's side.

"Lieutenant General, what happened to the soldiers and horses of those big men these days?"

Fan Xiong has not been patrolling the tower for a long time. Although he occasionally observes the situation on Liu Zheng's side, he doesn't pay close attention to the movements on Liu Zheng's side, so he wants to ask the lieutenant directly and get news from the lieutenant. .

The lieutenant general has been observing the enemy from the tower recently, in case Liu Zhengjun suddenly attacked the city.Therefore, he still knew the situation outside the city very well, and when Fan Xiong asked, he immediately spoke to Fan Xiong.

"Returning to Your Majesty, those big Han officers and soldiers outside the city haven't made much movement these days, and they haven't even seen the reinforcements. It's just that some people left outside the city and felled a lot of wood in the distant forest. out of town."

"A lot of wood has been cut down?"

"Well, they piled up the wood, and they don't know what it is for. It seems to be making some siege equipment."

Although he didn't understand what Liu Zheng and the others were doing, relying on his intuition, the deputy general believed that Liu Zheng and others were preparing for the siege.

After all, when Liu Zheng went to Haikou boasting that he would destroy the city within ten days, it was impossible not to prepare for anything.

After Fan Xiong heard the words of the lieutenant general, he was not so flustered.

"It's no wonder. After all, Liu Zheng said he was going to attack Xianglin City. How could he take down Xianglin City without making some preparations? I'm not worried about him making siege equipment. I have confidence in the city walls of Xianglin City, no? It’s so easy to break, I’ve been to Jiaozhi County, the height of our Xianglin City’s city wall is higher than that of Jiaozhou’s government, so it’s not so easy to break.”

Liu Zheng's actions showed that Liu Zheng was preparing and not doing nothing. If Liu Zheng didn't do anything and remained so calm, it would make Fan Xiong feel terrible.

It just so happened that when Fan Xiong appeared on the tower, Liu Zheng's troops were also assembled at this time.

Liu Zheng glanced at the tower from a distance, and then saw Fan Xiong at a glance, and immediately raised his voice and shouted loudly toward the tower.

"Fan Xiong, today is the ninth day!"

Fan Xiong didn't expect Liu Zheng to call him at this time, turned his head, looked away from his lieutenant general, and looked at Liu Zheng who was under the city.

After pondering for a while, Fan Xiong still responded to Liu Zheng in the city.

"Liu Zheng, do you know that it's already the ninth day, and there is one more day left. If you can't break through my Xianglin City, do you really want to retreat?"

Even now, Fan Xiong is still reluctant to compete head-on with Liu Zheng's men. He only hopes that he can survive these few days, and then Liu Zheng will withdraw and leave as he wished, so that this crisis can be resolved in this way.

But Liu Zheng didn't follow what he thought, but spoke to Fan Xiong in a playful tone.

"Yeah, there is still one more day, but I can't wait, I don't want to wait until the tenth day to break the city. Today, while you are on the tower, I will let you see with your own eyes how I broke yours. Like Forest City!"

As soon as Liu Zheng said a word, Fan Xiong on the gate tower, who was not so worried just now, suddenly changed his face, and immediately became nervous.
