No matter what Huang Chengyan thinks, anyway, for Fei Qian, the craftsmen who make crossbows must find a way to get a few.

Of course, the others such as paper-making and weapon-making......

The more the merrier!

Especially papermaking!

Paper has become a new grudge for Fidgen.

Fei Qian hates the days without paper very much, and he doesn't have to exercise his arm strength every day with a heavy wooden tablet, but mainly for the chrysanthemum of the butt! In these years, when you go to the toilet, you must first pick a clean one in the toilet chip without burrs......

Otherwise, you can imagine the sourness of a bamboo thorn or a wooden thorn in such a delicate place......

In the end, Fei Qian had to prepare a special one by himself, wash it every time, and then put it in a bag inside his sleeve.

Although it solved a little problem, it caused another mental illness, Fei Qian always felt that the sleeve smelled a little honey, lingering, this is really ......

Alas!

The problem of the Han Dynasty is not only this, but the biggest problem in front of Fei Qian now is the standard of the Qin Dynasty, which has been completely lost until now!

Liu Bang, an uneducated hooligan, after becoming the emperor, had his head pumped and he actually wanted to make a Han standard!

QIN RULER IS GENERALLY ABOUT 5-23CM, AND THEN LIU BANG'S KID SAID HOW CAN THE SIZE OF OUR HAN BE THE SAME AS QIN RULER? Then I added a little bit, probably the ruler is about 5-24CM, and then the other units of measurement are also slightly deviated, anyway, the original unified unit of measurement has become an extremely chaotic thing.

Later, the great pioneer Comrade Wang Mang, while practicing the concept of social average, also had further regulations on the unit of measurement, and also invented the vernier caliper......

In the current Han Dynasty, there are not only five length measurement grades of "centimeter ruler and long citation", but also two tiny units of measurement under the minute, milli and centimeter, and a batch of copper zhang, bamboo citation, copper jialiang, copper weighing rod and other items are manufactured to further measure the national measurement unit.

It's a pity, Comrade Wang Mang, this ......

Although the later Han Emperor was also useful for these, after all, he did not pursue details as much as Wang Mang, almost almost, almost, which led to the continuation of the national unit of measurement, although there were, but it was not accurate.

As a result, many instruments in the Han Dynasty, even to later generations are also extremely remarkable items, such as the Celestial Mixer, the Geodynamic Instrument, the Guide Car, etc., are only the only one, not to discuss whether it is practical, these complex machinery, can not be reproduced on a large scale......

The reason is that the standards are different, and even the length of the ruler between the teacher and the apprentice is different.

This also exists in the Huang family, Fei Qian and Huang Yueying looked at the dozen or so rulers placed on the ground, and scratched their heads a little......

These are the rulers used by the craftsmen of the Huang family, but there is a slight deviation in the length of these rulers, although there are not many, even if they are different from each other, they are only a few millimeters apart, but there is indeed a difference, and the attitude of the craftsmen of the Huang family is: "It's almost fine, just grind it twice." ”

Yes, most of the handmade utensils, if there are some inconsistencies when assembling, these craftsmen basically grind them with their hands, and they can frustrate it.

Fei Qian looked at these rulers, looked at Huang Yueying for a while, and said: "It's better to unify, find the best one, make a mold, and then pour a batch out, it's called 'Huang's ruler', isn't it better?" “

"'Huang's ruler'?" Huang Yueying rolled her eyes wide, and said with a smile, "Okay, I think it's good!" ”

The Huang craftsmen on the side also nodded.

People are always like this, and it is easier to accept what they agree with, but if Fei Qian jumps out and points out and says that all of your rulers are not good, and they must be replaced with new standard rulers, it is estimated that many craftsmen will muttered in their hearts......

Now take out the name of "Huang's ruler", and these people take it for granted and can accept it.

The scale standard is unified, this is a small problem, and there is a more tricky thing in front of Fei Qian - there are many reasons why the institutionalized production of blades in the Qin Dynasty died out in the Han Dynasty, and the most important factor is the change of material.

The Qin Dynasty used the extremely mature bronze technology to fight against the black iron technology that had just been developed by the other six countries......

It's not that the Qin Dynasty didn't want to use black iron technology, but that the Qin Dynasty was located in Guanxi at that time, first, there was no iron ore, and second, there were no talents who could cast iron, so they had to push bronze technology to the peak, but the victory of the Qin Dynasty did not mean the victory of bronze.

The ductility and rigidity of black iron are an absolute advantage for bronze, that is, the most fundamental reason for the use of steel as a weapon after the Han Dynasty.

However, the melting point of bronze is low, and it is very convenient to carry out mold processing, and then you can make various instruments in large quantities, and then after grinding and polishing, you can produce a whole batch of weapons.

However, for iron, pig iron is too brittle, and in order to fully display the ductility and rigidity of steel, it must be forged many times, but it is quite difficult to become a standard production of forging technology. In order to pursue consistency, it is inevitable to increase a lot of labor and repeated reprocessing, which will lead to a decrease in overall production......

Therefore, in the Han Dynasty, after the use of more advanced materials, the original institutionalized and standardized production of ordnance became a relatively impossible ideal state, so from top to bottom, no one slowly did this thankless task.

However, such a result is difficult for Feiqian to accept.

It turned out that he was still thinking that with the experience of those later generations, he would make an institutionalized ordnance standard, and then make an assembly line, and then wait for tons and tons of items to appear automatically, and in the end, everything would be fine as long as A was a moment......

But now, this dream has been punctured with a "poof" in front of the superficial metallurgical technology and equipment of the Han Dynasty!

In order to produce small objects such as steel arrowheads on a large scale, they must be cold-rolled steel like later generations, and then directly stamped and then ground and formed......

And among them, the gap between the Han Dynasty and later generations is not just a matter of a few machine tools!

I still take it for granted......

But what to do?

Fei Qian was a little worried, frowned, and looked at a piece of bronze and a piece of steel in his hand. Obviously, it is impossible to use the bronze of hundreds of years ago and the steel of the Han Dynasty to fight, but to transform the material that requires too much manpower into mechanization and scale, it is not possible to say two words and achieve a standard!

So where should you improve your first step?

Trouble!

Fei Qian was still frowning and thinking about it, and Huang Yueying on the side suddenly seemed to hear something, turned around and stretched out her arm, waved it, and said, "Father, we are here!" ”

I saw Huang Chengyan coming in a hurry, and when he heard Huang Yueying's voice, he only nodded slightly, his face was heavy, obviously something had happened.

Huang Chengyan walked in front of Fei Qian, sighed, and said, "Liu Jingzhou is here, I want to see you......"

Liu Jingzhou?

Liu Biao wants to see me?

What good can this big-tailed wolf do when he comes to the door?

Could it be......
