Spoiling History: Starting from the Three Kingdoms

There are so many types of crossbows?

Li Shimin was very surprised when he looked at the strange crossbow style, and then he remembered his favorite weapon:

I wonder how the bow will change in future generations?

Privately, Li Shimin felt that the selection criteria for his son's martial arts examination might have something to do with him.

Because this is how the selection of Baiqisi is now, you don't have to be able to use swords, but you must be able to shoot a strong bow, be good at riding horses, and be good at riding and shooting.

As for the selection criteria for Baiqisi, of course Li Shimin set them himself.

This criticized military examination standard was only a reminder to Li Shimin, because he had no intention of selecting generals based on such standards.

Both Li Shimin and Li Jing know very well, what is the use of just being strong?

At most, there are some differences. For example, Li Shimin emphasized the control of fighter planes before the battle, while Li Jing focused more on formulating military strategy.

But in short, seeing the various changes in the crossbow machine at this time, he was extremely curious about what the bow would become in the future.

So Li Shimin looked at the only general present and asked for help:

Is it possible for Lide to make a new bow based on this?

At this time, Yan Lide was too busy to deal with the Emperor of Tang Dynasty, so he could only give him a helpless look.

Only then did Li Shimin see that the Yan brothers were painting non-stop, trying to copy the displayed crossbows one by one.

Li Jing said with relief:

Based on this comparison, our Tang crossbow machine is just a belly crossbow, which is a bit crude.

Such pictures are nothing less than urgent help.

Du Ruhui also came over:

Everyone, compared to the various manufacturing methods of this crossbow machine, just as Huainanzi said that begging for fire is not as good as getting flint, it is more important to imitate the scientific methods of later generations.

As later generations said, the evolution of the crossbow machine is to avoid its shortcomings. This statement is as insightful as observing fire, so it can also be said that breeding horses is to nourish their strengths.

A simple view that goes straight to the point. This may be the scientific way to do things.

Li Shimin had always been able to listen to these words. Now when he heard what Du Ruhui said, he couldn't help but nod his head frequently, and then asked:

According to Keming's opinion, how can we imitate this science?

He can see the power of future generations, but the problem is that he has never really seen what the classics of physical science look like, so he is a little confused.

Du Ruhui smiled at this:

Later generations have long said that arithmetic has a higher status than science.

If your Majesty holds the imperial examination, please also re-learn arithmetic.

…

In the Chengdu government office, Liu Bei laughed when he saw the thing marked with the wheel crossbow:

Isn't this Mrs. Huang's crossbow?

Kong Ming chuckled:

It's still slightly different, but the underlying ideas are quite similar.

Kong Ming is no stranger to this thing.

The eight-oxen crossbow obtained from later generations relied on the power of a winch. The compatibility between this thing and the round cart was really good, so in the end, the marine giant crossbow on the giant boat had multiple winches linked together, and it was driven by people pedaling the car.

Before the Battle of Jingxiang, Kong Ming also communicated with his wife about the issue of reducing the size of the Eight Ox Crossbow.

In the end, after becoming smaller, the crossbow arm was too easy to be broken by the compound three-bow, so we had to give up.

However, the winch installed on the hand-held crossbow has been retained. This type of special bow is more powerful, but the corresponding winch takes a little longer.

My wife wrote that the advantage is that this thing is easier to use. It can be used in a group of three people with three winch crossbows. Two people only have to cock the crossbow, and one person only has to shoot.

The only drawback is that the crossbow string material and winch are not cheap. If you want to equip a squad, the price will almost catch up with the cavalry.

And if you calculate the daily maintenance costs, it is three points more expensive than the cavalry...

Therefore, after Kongming got it, he studied it for a while and chose to remove the more expensive winch again.

Each crossbow has a slot for removing the winch. In this way, the crossbow auxiliaries only need to carry the winch. When they need to string the crossbow, they only need to insert the winch. Just dismantle it and use it for other crossbows.

The only pity is that it took a lot of time to write letters and research and discussions. By the time we had a clear idea, the Jingxiang War was over.

So now I can only produce silently, planning to give the enemy a big surprise when I have time.

Therefore, the people from the Chengdu government office went directly to see the hand-cranked gear steel crossbow.

A powerful crossbow made of hundreds of steels...

Kong Ming looked at it carefully with joy on his face and murmured:

On the contrary, the authorities are confused.

From the early Han Dynasty to the present, crossbows have never been made of pure wood. They are generally made of wood for the front crossbow arms and iron or copper for the rear crossbow arms.

Not using pure metal is probably because copper and iron are not tough enough, but the iron being smelted today is much stronger than before. Maybe we can really try it?

Kong Ming was very interested. The cost of this thing was getting more and more expensive, and it was destined to be impossible to install now.

But I feel itchy if I don’t build one and try it out.

It is also because of this that everyone in the Chengdu government office wants to talk about the evolution of this crossbow machine more relaxedly and comfortably.

Liu Ba tried:

If we go by the lever theory, the best one to use in battle is the goat crossbow?

Kong Ming smiled gently:

Zichu, why don't you tell me?

Liu Ba recalled:

Kong Ming once took a class at Xiao Tai School. I was also present at that time. At that time, he used Moqiu (seesaw) as an example to explain the theory of standard weight.

At that time, I calculated on the spot that the longer the standard (moment arm), the smaller the gravity (force).

As he spoke, Liu Ba pointed at the goat crossbow structure and said:

Isn't this winding tool just a deformed Moqiu? If you pull it from the front to the back, the machine will push the crossbow string back. Although the length changes with the position of the bow string,...

Liu Ba was slightly nervous, but after getting an encouraging look from Kong Ming, he still said loudly:

However, from the beginning to the end, the mark held in this section is always longer than the bowstring, so stringing is more labor-saving. Compared with the winch, it is cheaper to make and faster to string.

Liu Bei's face was confused, Zhang Fei was already a little dizzy, and Fazheng was staring at the crossbow diagram and thinking hard.

Kong Ming laughed and clapped his hands:

Zi Chu is a great talent! Why don't you come and study this with me!

[However, the fact that the Chinese classical crossbow machine has not been improved is also due to many factors.

First of all, of course, the Ming Dynasty did not pay attention to mathematics, which made it impossible to change it even if it wanted to.

Secondly, there was the rapid development of firearms in the Ming Dynasty. Firearms were the superior replacement of crossbows, so naturally there was no need to study crossbows.

But at this point, our story about the strategy of the Western Regions in the early Tang Dynasty has officially come to an end.

After all, after Xue Rengui's victory in Yunzhou, and with the death of Emperor Gaozong, the hot woman finally came to the forefront.

So in the next issue, let us turn our attention to the sea and explore together:

How did the Tang Dynasty completely break the backbone of the Wonu Kingdom in one battle?

Then see you in the next issue~]

〖Where is I, Li Shi𪟝? I, Xu Maogong of the Tang Dynasty, am so shameless, can't I have a separate issue?

I have no choice but to be given a surname and then have my surname taken away from me. This can be regarded as my first experience in the Tang Dynasty. Compared with the other two, I don't know if I can beat him. I'm sure he will be the most humiliating.

By the way, Zhenguan's martial arts is really powerful. In comparison, Xiao Song...

There were still people in the Song Dynasty who were dissatisfied with Erfeng, such as the historical duel between Wanyan Gou and Qin Hui.

Indeed, when you mentioned it, I remembered it. Zhao Gou said that Erfeng had a good reputation and that Emperor Wen of Han was not sincere in his treatment of others. Then Qin Hui quickly praised him and said: Your Majesty, you have a bad reputation and you are also sincere in your treatment of others. As long as you work hard a little, you will not be able to treat others sincerely. When it comes to Tang Zong’s Chinese writing, Yao and Shun can also be compared.

All I can say is that he is worthy of Wanyan Gou. 〗
