"Professional?" Liu Ye's eyes finally regained some brilliance, well, it was a look that seemed to explode in silence.

Since Guo Jia still dares to mention any major, maybe there is no such thing as "there is a precedence in hearing the Tao, and there is a specialization in the art industry", but everyone knows the same truth! For Guo Jia's rude request, he Liu Ye got up early in the morning and studied hard, starting from scratch, studying hard, only for such a little time, it is good to have results, Guo Jia actually talks to him professionally? Sincerity wants to force people to explode, right?!

However, after this period of hard work, Liu Ye has already learned more or less about Guo Jia's thoughts, well, it is his self-righteous understanding.

I have to say that in ancient times, the limitations of talents were too strong. Take the matter of today, a scholar will never care about the carpenter's business; And almost all of those who learn carpentry are people who have never read a book. Although it cannot be said that people who have not read books are not smart enough, this kind of people often have a very big disadvantage, that is, they can't think!

For example, what kind of land, how the ancestors planted, today's farmers still plant like that, as long as they blindly follow the experience left by their ancestors, keep repeating, do not need to think, and gradually become unable to think. There are even some special experiences, because they have not read books, they cannot be recorded in detail, and they can only be taught by hand, so that some experiences cannot be summarized at all, and some skills will eventually be lost.

It is precisely because the people at the bottom do not think, and the smart people at the top do not put their minds on these aspects, that the progress in these productivity areas is very slow. Since the Iron Age, so to speak. Over the centuries, there have been some advances in the social system and classes. In terms of people's living standards, they are almost standing still.

After these days of research. Liu Ye is deeply aware of this problem, those so-called carpenter's "textbooks" are actually not practical at all, and there are even many outrageous mistakes.

Obviously, this kind of thing is not for real carpenters, because others can't understand it at all, and it is also a craft that is learned directly from the master. These "textbooks" are actually some laymen who don't understand it at all. Leave it to other laymen who don't need to understand it at all.

Over the years, in terms of weapons, they have become sharper and harder, and even various shapes and styles have eighteen kinds of martial arts. And other stupid guys like catapults have not made any progress from beginning to end, and even have completely regressed!

Think about it. In so many years of peacetime, there were no craftsmen who had ever made catapults, so the direct teaching of such people to people was completely unmarketable. It is estimated that it has long been lost. Therefore, the only way to build a so-called catapult now is to follow these so-called "textbooks".

Make a catapult now. There is no form, but no god. Everywhere there are small problems with the details, and it is precisely these small problems. So that the current catapult, whether it is power, crosshair, assembly, operation, etc., can not play a very good effect.

So the catapult on the battlefield today, in the words of Yang Xiu's famous saying, is "chicken ribs, chicken ribs, it is a pity to abandon them, and the food is tasteless." ”

And now, Guo Jia is semi-forced to ask Liu Ye, a smart reader, to come and study this catapult, so even if he can't carry forward the catapult and how powerful the transformation is, at least Liu Ye should be able to solve the details of the catapult under careful research, so that it can play the real effect it should have!

This is Liu Ye's speculation about Guo Jia's thoughts, and it is precisely because of this speculation that Liu Ye persevered. Because Liu Ye found that Guo Jia's thinking was indeed as peculiar as the legend, this kind of thing, others couldn't think of it at all, and no one would think about it, but Guo Jia took it into account, and the reason why the catapult was no longer magical was also speculated clearly. Moreover, Liu Ye himself believes that what he is doing now is very meaningful. This kind of thing, once successfully studied, is definitely of considerable value in this period of war!

Of course, if he really studies it, Liu Ye will definitely have to weigh it carefully, whether he has the ability to master it safely

"Tut-tut, you're actually a written record? Have you ever experimented? These seem to be all speculations that you take for granted, right? Do you think it will really work? Guo Jia shook his head and sighed.

Even if you've never seen a pig run, at least you've eaten pork!

Although he Guo Jia is a liberal arts student, he has also studied mathematics, physics and chemistry. Even if you haven't studied mathematics, physics and chemistry, you should always have an impression of those architectural drawings.

To put it simply, at this time, the "professional" in Guo Jia's eyes should at least draw a three-dimensional figure of a catapult, which is marked with how many meters long, how wide, how high, and what angle is, and then mark what material is used.

Perhaps more professional, in addition to the complete graphics, there should also be a pattern of each part, so that the craftsmen can make it according to the pattern, as long as the template of all the parts is set, then it can be easily mass-produced, and finally all the parts are assembled to form a real catapult.

When fighting, it is easy to carry, it can be assembled and disassembled at any time, even if it really can't be taken away, it can be destroyed directly, after all, those parts can be easily made, and they can be kept and carried by the grain and grass troops in peacetime. In this way, the changes on the battlefield can be much more maneuverable. Turn catapults into a universal threat like bows and arrows!

Well, the only problem is the problem of ammunition, after all, such a large stone is not so easy to solve.

However, if it can really achieve what Guo Jia said, it will definitely be a qualitative leap for today's era!

"You, don't talk nonsense if you don't understand!" Liu Ye blushed and shouted excitedly.

This is the result of his research in so many days! Liu Ye believes that Guo Jia is definitely not an expert, and he is also a layman who writes those so-called "textbooks", at most he knows a fur! If Guo Jia is really that powerful, do you still need to let him Liu Ye study it!

Besides, Guo Jia just looked at it casually and made such an evaluation, which gave people a rather irresponsible feeling!

"I'm just asking you, do you have these things that only exist in theory? Have you ever done an experiment to prove it? Guo Jia said directly, Liu Ye would never have imagined at this time that Guo Jia's level is already a real expert in this era! It's just that Guo Jia is too lazy to use his brains in that regard.

Moreover, in terms of Guo Jia's scientific and pragmatic truth-seeking attitude, if it is really up to him, it will definitely take more time than Liu Ye, and most of the time will definitely be used by Guo Jia for fine-tuning. Guo Jia must set a highest, farthest, and most perfect catapult parabola. (To be continued.) )
