Chapter 208 The Trebuchet

Xu Changfu didn't think it was possible for Wang Dong to see any problems from Hou Junji's construction machinery. After all, these things were all made by the military craftsmen of the Tang Dynasty. Among the forces of the surrounding countries at this time, the level of civilization of the Tang Dynasty was obviously the highest. And the level of the military craftsman of the Tang Dynasty is naturally the well-deserved number one among the surrounding forces.

If the individual combat ability is compared with the power of the Western Turks and Tubo, there may be differences between the Tang people and them, but when it comes to equipment manufacturing.Datang is really dissatisfied with anyone.

Therefore, when Hou Junji and Xu Changfu heard Wang Dong's words, the first reaction was that this kid was a bit arrogant.

Dare to raise an argument in front of Hou Junji, somewhat ignorant.

Thinking of this, Xu Changfu couldn't help breaking out in cold sweat, and Hou Junji was not very happy, although he didn't turn cold, but he couldn't help smiling, looking at Wang Dong and waiting for him to say something.

Wang Dong looked at the equipment models on the table. It is impossible to say that there is no pressure in his heart. According to his original personality, he must be blowing rainbow farts at the moment, but the system gave him a task and he can only do it. Bite the bullet and go on.

Wang Dong took two steps directly, gave Hou Junji a questioning look, cupped his hands and said:

"Master Shang Shu, I think there is still a way to improve this catapult."

Hou Junji frowned. He didn't quite believe that Wang Dong could say anything useful. After all, Wang Dong was just a civil servant in Lingnan before. His martial arts might be because he loved practicing martial arts, but he It is obviously unreliable for people who have never fought a siege battle to develop any engineering equipment for those who have never fought a war.

He thought to himself that Wang Dong probably read as many books as those literati and had some fantastic ideas. He always felt that what he came up with would be useful on the battlefield, but after it was actually used in the battle formation , not everyone is Mr. Wolong, who can know three-thirds of the world by sitting in Wolongzhong. A casual drawing is like a wooden cow or a flowing horse.

But now Wang Dong didn't say anything, and he didn't need to save Bo Wangdong's face, so he asked, "Oh, do you think there's anything wrong with this catapult?"

At this time, the catapult in the case is a typical manpower lever catapult. This kind of thing had appeared as early as the Spring and Autumn Period and the Warring States Period, and it had been developed to a very complete level in the Tang Dynasty. In his opinion, it is impossible for Wang Dong to come up with any unique insights on such a highly professional thing as a catapult.

But in Wang Dong’s view, the human-powered catapult is actually just a very narrow path on the technological road of catapults. For a long time in ancient times, the development of Chinese catapults was basically based on the human investment vehicle. Hei, there are many improvements, such as the scientific nature of the lever system and the structural modification of the catapult, etc., so that they can be moved and disassembled and transported more easily, but as far as the catapult is concerned, many technology trees are actually different. Did not click on.

So Wang Dong said with a smile: "There is no strong enemy with a large city in Longyou. I think the city that Lord Shangshu will use these construction machinery to attack will not be in a place with very convenient transportation?"

Hou Junji smiled when he heard the words. It was not a surprise to him that Wang Dong could guess that they were making these siege equipment to attack the countries of the Western Regions. Such a conclusion can also be drawn.

Hou Junji did not respond positively, which in Wang Dong's view was equivalent to acquiescing.

So Wang Dong continued: "Since the journey is far away, the number of people I can take with you will not be very large. I dare to ask the general. If a catapult like this is to be built on the scale of a large engineering vehicle, I am afraid it will not take 30 people to launch it once." Someone will pull me?"

"If you want to attack a big city, the catapults operated by 30 people must be able to cover the firepower of the defenders on the city wall. If you want to increase the firepower, even 50 people may not be able to defeat it."

"The catapult requires a lot of manpower."

Hou Junji nodded and admitted that the number of people a catapult should be equipped with is actually a military secret to some extent. Wang Dong guessed that the number of people is actually small, but he will not continue to add detailed figures, just want to continue Listen to what else Wang Dong has to say next.

Wang Dong smiled and said: "Yes, then it is a catapult, and the team needs at least dozens of people. If you are attacking a city, ten and twenty catapults are activated at the same time, and the number of people brought with it may not be thousands, and Even with such a catapult, it may not be possible to throw huge stones and destroy the city wall at once."

Xu Changfu and Hou Junji couldn't help but be surprised when they heard Wang Dong's words. According to what he meant, could it be that he had a way to create a catapult that could launch heavier stones with fewer people? Can the son destroy the city wall?
Hou Junji couldn't help but gave Xu Changfu a look. He couldn't ask directly at this time, and Xu Changfu is still Wang Dong's boss at this time, so he can speak for him. Xu Changfu understood, and quickly said: "Wang Dong Chang Shi, don't be so secretive anymore, but you tell me your plan."

Wang Dong smiled when he heard the words, cupped his hands to Hou Junji and said, "Master Shangshu, please give me a pen and paper."

"Paper and pen? Wait..."

Hou Junji summoned a soldier and told him to bring a pen, ink, paper and inkstone to spread on the table. Wang Dong strode forward, raised a wolf hair fine brush, filled it with ink, and drew it horizontally on a wide open white paper. Vertical lines quickly draw a catapult.

Both Hou Junji and Xu Changfu stepped forward curiously. They found that the difference between the two ends of the force arm of the catapult drawn by Wang Dong was very large. When seeing this design, Hou Junji's first reaction was that this thing is not Can't move.

But then Wang Dong drew a big weight box on the place where it should be pulled by human power.

Hou Junji and Xu Changfu were taken aback for a moment, and Hou Junji was the first to react. He quickly understood that the principle of this thing is to use gravity instead of manpower to start the catapult.

Wonderful.

The principle of the gravity catapult can be said to be quite simple. It does not require any physical knowledge at all, and it can be understood at a glance with ordinary life experience.It is nothing more than changing the traction rope used by people or livestock in the manpower catapult into a counterweight box, filling the middle box with stones, and then pulling the counterweight box to a high place with human or animal power to fix it, and then untie it when it is time to launch Fixed, the distribution box sinks once, driving the movement of the sling rod, and throwing the stones on the sling rod far away.

But it is such a simple design, if no one reminds it, it is difficult for ordinary people to think of it.
