"There are so many types of crossbows?"

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

"I don't know what has changed in the bow of the future?"

From his own heart, Li Shimin felt that the selection criteria for his son's martial arts were likely to be related to him.

Because the selection of the hundred horsemen is like this now, you can not use a sword, but you must be able to shoot a strong bow, be good at riding horses, and be able to ride and shoot.

As for the selection criteria for the Hundred Cavalry Division, of course, Li Shimin set it himself.

This criticized martial arts standard can only be regarded as a wake-up call for Li Shimin, because he did not intend to select generals according to such standards.

He Li Shimin and Li Jing couldn't be clearer, what's the use of just having a lot of strength?

At most, there is a little disagreement, for example, Li Shimin emphasizes more on the control of fighters when they are in battle, and Li Jing focuses more on the formulation of military strategy.

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

So Li Shimin's eyes for help were handed to the only general who was present as a prisoner:

"Lide may make a new bow based on this?"

At this time, Yan Lide was already too busy to have time to perfunctory the Tang Emperor, 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 crossbow machines on display one by one.

Li Jing was relieved:

"According to this comparison, now my Tang crossbow machine is just a belly crossbow, which is a little simple."

"Such plans are tantamount to urgent assistance."

Du Ruhui also came over:

"Everyone, compared with the various production methods of this crossbow machine, as "Huainanzi" said, 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 like watching the fire, so it can also be said that breeding horses are all for raising their strengths."

"A simple view goes straight to the point, and this may be the scientific way to do things."

Li Shimin has always listened to these words, and when he heard Du Ruhui say it at this time, he couldn't help nodding frequently, and then asked:

"In Ikemin's opinion, how can we imitate this science?"

He can see the strength of later generations, but the problem is that he has not really seen what the classics of physical science look like, so he is also a little at a loss.

Du Ruhui smiled at this:

"Later generations have long said that arithmetic is more important than science."

"If Your Majesty opens the imperial examination, please recalculate the study."

……

Chengdu Mansion, Liu Bei smiled as soon as he saw the thing marked with a winch crossbow:

"Isn't this Madame Huang's crossbow?"

Kong Ming smiled:

"It's still a little different, but the idea inside is quite similar."

Kong Ming is no stranger to this thing.

The eight-bull crossbow obtained from later generations is to use the winch to exert force, and the compatibility of this thing and the round car is too good, so in the end, the ship giant crossbow on the giant boat is a plurality of winches linkage, and the car is wound by a human pedaling car.

Before the battle of Jingxiang, Kong Ming also corresponded with his wife and talked about the problem of shrinking the Eight Ox Crossbow.

In the end, because it became smaller, the crossbow arm was too easily pulled off by the compound three bows, so it had to be stopped.

However, the winch mounted on the hand-held crossbow was retained, and the special bow was more powerful, but the corresponding winch took a little longer to get it up.

The lady wrote to say that the advantage was that it was easier to use, and that it was possible to carry three winch crossbows in groups of three, two of whom were only in charge of winding, and one of whom was only in charge of shooting.

It's just that the only drawback is that the strong crossbow string material and the price of the winch are really not cheap, if you want to equip a team, the price is about to catch up with the cavalry.

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

Therefore, Kong Ming studied it for a period of time after getting it, and chose to dismantle the more expensive winch again.

Each crossbow has a slot that can be removed from the winch, so that the crossbowmen's auxiliaries only need to carry the winch, and when it is necessary to wind the crossbow, they only need to plug the winch, and then remove it for other crossbows after the twisting.

The only pity is that it takes a lot of time to write a letter back and forth and research and discussion, and by the time there is an eyebrow, the Jingxiang War has already ended.

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

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

"A hundred steel-made crossbows......"

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

"On the contrary, the authorities are confused."

From the former Han Dynasty to the present, the crossbow machine has never been pure wood, generally the front crossbow arm is made of wood, and the rear machine is used to expand the Wangshan and other iron or copper.

It doesn't have to do with pure metal or copper and iron is not tough enough, but now the iron smelted is much stronger than in the past, maybe you can really try it?

Kong Ming was full of interest, this thing is getting more and more expensive, and now it is destined to be impossible to install.

But if you don't make one out and try it, it's itchy in your heart.

It is also for this reason that the people of the Chengdu government should talk about the evolution of this crossbow machine more easily and comfortably.

Liu Ba tried:

"According to the lever, the best person to use in battle is the goat crossbow?"

Kong Ming smiled gently:

"Zichu might as well talk about it?"

Liu Ba recalled:

"Kong Ming used to take a class at Xiaotaixue, and I was also present at that time, and at that time, I used Moqiu (seesaw) as an example to talk about the importance of standards."

"At that time, it was calculated on the spot, the longer the target (force arm), the smaller the weight (force)."

Saying that, Liu Ba pointed to the goat crossbow structure and said:

"Isn't this winding tool just a deformed grinder? Pulling back from the front, the machine expands the crossbow string backwards, although the length of the mark changes with the position of the bowstring, but ......"

Liu Ba was a little nervous, and after getting an encouraging look from Kong Ming, he still said loudly:

"However, from beginning to end, the mark of this section is always longer than the mark of the bowstring, so the winding is more labor-saving, and the price is lower and the winding is faster than the winch."

Liu Bei's face was dazed, Zhang Fei was already a little dazed, and Fa Zheng was staring at the crossbow diagram and thinking hard.

Kong Ming laughed and clapped his hands:

"The beginning of the child! Why don't you come and study this with me? ”

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

First of all, of course, the Ming Dynasty did not pay attention to mathematics, which led to the inability to change it.

The second is the rapid development of firearms in the Ming Dynasty, firearms are the superior replacement of crossbow machines, so there is naturally no need to study crossbow machines.

But at this point, our talk about the Western Regions strategy in the early Tang Dynasty has officially ended.

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

So in the next issue, let's look at the sea and explore together:

How did the Tang Dynasty completely break the backbone of the Japanese slave state in a war?

Then we'll see you in the next issue~]

What about me? My Tang Dynasty Xu Maogong is so faceless, can't I have a separate issue?

There is no way, being given a surname first and then being taken away from the surname, it can be regarded as the first time to open the Tang Dynasty, compared to the other two, I don't know if I can fight, the most faceless is certain.

It is said that Zhenguan's martial arts are really fierce, in comparison, Xiao Song......

There were still people in the Song Dynasty who were not convinced by Erfeng, such as the one between Wanyan and Qin Hui in history.

Indeed, as soon as you say it, I remember, Zhao Gou said that Erfeng had a good name, and said that Emperor Wen of Han was not sincere in treating people, and then Qin Hui hurriedly held his stinky feet: Say Your Majesty, you are not good at name, but also treat people sincerely, as long as you work hard, don't talk about Tang Zong Hanwen, Yao Shun can also compare.

It can only be said that it is worthy of being a complete face. 〗
