Special weapons workshop, this is a special place in the science and technology city, where is the special, that is to say, most of the things here, in addition to their own use, are out of drawings, this drawings, the final landing point, will be on Li Er's desk, as for where he gave, it is not in the hands of Yang Qiao, and most of the time, it will pass through the hands of the Ministry of War, to the head of the new weapons supervisor, eh, to the old weapons supervisor, he can't do it.

"Old weapons supervisors, horses, how can you say this, they, at this time, they can't even make a trebuchet, not that the quality of their work is poor, what they do is more precise than what our new weapons supervisor does, but unfortunately, their thinking is relatively backward."

Yang Qiao and Niu Baobao listened with great interest to the introduction of the old weapons supervisor by the craftsman who came to learn.

"This old weapons supervisor, making a weapon, is done by one person, from beginning to end, perhaps, only when the materials are prepared, they don't do it, and when they can, even, even the preparation materials, they prepare it themselves, which means that they can make it themselves with confidence."

Let's take the bow as an example, a bow, a craftsman, can be made for a few years, because of the emergence of high-strength glue, forehead, high-strength glue, is also made by the Yang family, so this bow is made of composite bows.

It is also because of the emergence of this high-strength glue that the speed of the craftsman to make the bow has accelerated, not the speed of a bow, but the quantity, for example, before, a craftsman, a year to make so many good bows, only a handful, these bows, is made in a year, and then, it will take two years to trim, three years to leave the factory, which has exhausted his mental strength, but, because of the emergence of this high-strength glue, although the speed is not fast, but the number has increased, which is also a guarantee for the Tang Dynasty archers to become an army.

Again, this bow, as long as it can open the arrow, is an archer, but if you want to shoot accurately, you can't say it, but an arrow array really doesn't need a good archer, as long as it can be pulled away, it can listen to the command.

That's it, this old armory supervisor has raised a group of craftsmen who manufacture independently, so they also have to make their own trebuchets, well, don't worry, you can't make it in a year, two years, two years, three years.

However, this large weapon, naturally a person is not good, so you need apprentices, and these craftsmen like to let apprentices do simple things, such as making trebuchets base, brackets or something, but they also like to use the measurement method, this is broken, your arm length, but not my arm length, this is the mistake, finally, when assembling, every part is a high-quality product, but, together, it is not a high-quality product, well, it can't be installed.

"After all, the people in this old weapons supervisor are more bullish, and they don't listen to what they say, but we really admire their ability to make bows, so our new weapons supervisors can make arrows and bowstrings, but they don't make bows, and the bows we make are not as good as their ones."

In fact, it means that they like to divide labor and cooperate, and a person making a product is not used to it, not that they can't do it, but they are not used to it.

"Brother-in-law, don't you also make bows here, or do you want to use your skills?"

On the side, Niu Baobao was a little angry, and there were such people.

"I'm here, no, to really talk about it, my bow here is really not as good as their bow, you know, their bow, to a general, any one, can shoot accurately, and I here, although it is also accurate, but, have you found that either the strength is small, or the strength is large, and ordinary people use it, but it is a little worse, especially here with me, the best, I use, the strong bow, and the ones you use, this production time, even longer, what, you say fast, you don't know, In order to make that bow, I used many advanced things, which are not something that ordinary people can learn. ”

Yes, some of the bows made by Yang Qiao, what stress calculation, what balance force calculation, what ......

These are all modified at the suggestion of the talker, and they are all modified by some of the ways of making furniture in later generations, for example, this bow, one side is hard, it needs to be softened with something, or, to modify, drill a hole, this hole, can not affect the use of do not to pull the string, from here to break, this calculation, so complicated, Yang Qiao can't calculate, it all depends on the chatter system.

"Princess, we can't learn this!"

The baby cow took his bow to the craftsman and asked him to study it.

"Don't you have a thinner place than this side, isn't it harder here, so you have to thin it to ensure balance, and here, you actually drilled a very shallow hole."

The so-called very shallow, that is, only a circle, looks like a hole, the craftsman used his hand to break the bow arm, and immediately discovered the mystery.

"This is to prevent deformation, is it, this bow is made quickly, well, it should not be more than a year."

Sure enough, it was a craftsman who made bows, well, perhaps, their level was worse, perhaps, it was because they were young, and their minds were more lively, so they were transferred to the new weapons supervisor by the military department.

No, I just looked at it a few times and broke it, and I saw a lot of things.

"You can see it all, can't you do it?"

The baby cow was a little curious.

"Hey, princess, it's not just that I can't do it, it's the best archer in the old armory, he can't do it, just these holes, whatever, I don't know where to drill, and this thinning, this, capable, but where they can cut it, it's not sure what they can do, what they can do is to make it according to the tradition, and it will take a few years to finalize it, so that their technology is the best."

"So, what about your new armory?"

"Well, princess, our new weapons supervisor has learned to divide labor and cooperate, for example, this rocket bamboo tube, generally two or three people to do, some to do aging treatment, some to boring, and this rocket, some to make warheads, some to make bullets, and some to make wings, moreover, this rocket, this distance is getting farther and farther."

The so-called rockets are not the rockets of later generations, but a firework-like thing, but the barrel that is shot out is made of bamboo, bamboo tube, is a disposable, warhead, and is also packaged in paper, which will contain some flammable incendiary powder, and some pieces of broken iron or something, the lethality is huge, well, when attacking the city, kill and injure the enemy's defending power, and block them from killing and injuring our siege team.

When fighting in the field, naturally, it is to kill and injure the living forces, or that sentence, but it's a pity, the number is too small, and the transportation is troublesome.

"Recently, we are developing the inner wall of this bamboo tube, first carbonized treatment, and then ceramic treatment, so that this bazooka can be used many times, temporarily speaking, it has been developed to use five times, however, it is still not guaranteed, and some are not handled well, which will make the rocket explode directly inside."

"Well, your idea is good, what about you, here, you can see how the experiment is carried out here, how it is recorded, this record is the most important, I found that your record is a little poor, your experiment, every time, have you done a good record?"

"No, there are records, every time, however, it is relatively simple, such as, today, what tests have been done, what is the effect, as for the detailed information you said, but there is no record, all in the heart of this craftsman!"

"Remember in your heart, are you afraid that others will know, remember, internally, especially the tasks assigned by the public, don't keep them secret, it's just a personal job, it's a big deal to hide the records, but you can't keep them in your heart, remember them in your heart, there will always be a time to forget."

"Listen well, this is something that my brother-in-law taught you, don't think that when you see the real thing, you learn something, you see the real thing, don't record it, forget it when the time comes, or you need to come back to see it, but, you record it, as long as you look through the record, isn't it?"

For Li Er, the princess is also educating this craftsman on the side, well, there are several craftsmen, this time, there are four craftsmen who are studying and visiting.

"Okay, princess, we've all remembered."

"If you say this palace, don't record it, if you do, it doesn't make sense, isn't it!"
