Three Kingdoms

Huang Chengyan took back the missing mark, pulled out the ruler, and looked at it. He couldn't figure it out for a while. As a ruler that subdivides moments, shouldn't the distance between each scale be the same? Is this also a mistake? ?

Seeing that Huang Chengyan also didn't understand, Fei Qian said: "Huang Gong, actually this problem is not too big, but if you want to be more precise... Generally speaking, there is nothing wrong with the equal distance of the ruler, but this ruler is used On water, and for a tube like this, the dripping speed when it is full is different from the speed when it is half full of water, so this scale..."

Huang Chengyan reacted immediately, and immediately called his servants to bring out two similar small wooden barrels. One was filled with water, and the other was only half filled. Then they used a small iron cone to make a small hole in the bottom. , I carefully observed the water jets from two wooden barrels with different amounts of water. Sure enough, as Fei Qian said, the sizes are not the same, and as time goes by, the water levels of the two barrels with different amounts of water drop by the same amount. different……

"So that's it!" Pang Tong, who was watching on the side, suddenly figured it out and said, "Water also has weight! This bucket has a lot of water, so it is naturally heavier. The water flow rate is faster than this bucket, so this benchmark Judging from this situation, the scale should indeed not have the same distance up and down..."

Huang Chengyan also figured it out. When Pang Tong said this, he praised: "Shi Yuan is good. Recently, it seems that he has not only read classics and history, but also put some effort into investigating things?"

Pang Tong was not modest, but felt a little proud and said, "That's natural!"

Huang Chengyan said to Fei Qian: "Ziyuan is very observant. It's rare that he understands the study of things so well. It's amazing!" He thought to himself that Pang Tong and Pang Shiyuan had no interest in studying things at first, but now they actually understand a little. Could it be that he is doing this? Under the influence of Fei Qian Fei Ziyuan?

And that small scale, was it also made by this Fei Qian?

This Feiqian Feiziyuan is indeed a person that Pang Gong values ​​​​in his eyes. He is knowledgeable and talented...

Thinking of this, Huang Chengyan smiled and said: "It's getting late now, you two might as well stay here. I have already asked people to summon the craftsmen, and Riyuan will have people send the materials needed for the arrows here tomorrow. Then we can start making arrows!”

Pang Tong didn't care, he just stayed there, since the Pang family and the Huang family were so familiar with each other.

On the other hand, Fei Qian couldn't help but feel overjoyed after hearing this. A stone was finally lifted from his heart, and he bowed his hands to Huang Chengyan, the head of the Huang family, and thanked him.

When it came to making arrows, Fei Qian was actually a little curious. After all, bows and arrows were long-range weapons for individual soldiers in the Han Dynasty. He happened to meet Huang Chengyan, a master maker of the Huang family, and took this opportunity to ask him for advice.

When it came to making weapons, this was Huang Chengyan's strong point. With his bold personality, he had no intention of hiding anything, so he asked his servants to fetch a few arrows.

It turns out that those fired with a bow are called arrows, while those fired with a crossbow are called arrows.

These arrows are very exquisite. Although Fei Qian doesn't understand them very well, they feel very good in his hands. The arrows are sharp, the shafts are smooth, the tail feathers are straight, and the overall proportions are coordinated and full of beauty.

Fei Qian took the arrows and arrows, observed and compared them, and listened to the introduction of Huang Chengyan, the head of the Huang family.

This time Cai Mao said he wanted to train two thousand archers, so naturally he wanted to train arrows.

The arrows of the Han Dynasty are similar to the impression of Fei Qian's later generations. They are composed of three parts, the arrowhead, the arrow shaft and the tail feather.

According to Huang Chengyan, since it is ordinary arrow making in the military, it does not require precision craftsmanship. It only needs to be qualified, so it is not too difficult. If you want to customize a bow and arrow for an individual, it is called a complicated matter. It not only requires good materials. , but also to consider everything from hand length to arm length, and then from the strength of the bow to the center of gravity of the arrow, everything must be in line with the person using the bow to be the best. These arrows are actually samples left by someone just now... …

Pang Tong said "Oh" and said, "I must have just come to Han to find Huang Gong to make arrows?"

Huang Chengyan nodded and said: "Exactly, Han Sheng's bow is relatively strong, and ordinary craftsmen's arrows can be used, but after all, they are not as good as customized ones, so they came to me again..."

Han Sheng? Huang Hansheng? Fei Qian was stunned, this guy is a great guy...

However, Huang Chengyan and Pang Tong did not talk about Huang Hansheng again, which made it difficult for Fei Qian to ask. After all, he did not know him. It was a bit strange to ask rashly. And if he was lying, it would be even worse if he was exposed. , so I can only wait until I have the opportunity to learn more next time...

Huang Chengyan pulled out the arrow head from the shaft, handed it to Fei Qian to look at, and said: "The arrow is divided into two parts, one is called the arrow blade, and the other is the arrow collar..."

The arrow blade is naturally the triangular point-edged part used to pierce people, and this is the first time I have seen the arrow collar Fei Qian.

According to Huang Chengyan, this arrow collar is used to insert into the shaft, and it must be thin and hard. The length of the arrow collar must be longer than the length of the arrow. If it is short and is randomly checked, it will be treated as "out of control" "The crime of...

The arrows are not the most delicate part, nor are they the most troublesome. After all, the arrows are molded with molten iron and polished in batches. Although the requirements are high, there are not too many processes.

The most important process of making arrows is the making of arrow shafts.

The material used to make arrow shafts is spring wood.

It does not mean that there is a kind of tree named spring, but it means that it is best to cut down trees in spring, as autumn trees tend to crack easily, and trees located on the shady side of mountains should be cut down.

But anyway, the materials are provided by Yiji, so there is no need to worry about the wood...

The most important requirement for an arrow shaft is that it must be straight!

However, wood is often not always straight. If the direction of the wood grain is ignored, the arrow shaft will be easily broken and will be of inferior quality. A good arrow shaft must follow the wood grain.

Therefore, if the wood grain is curved, it must be manually roasted first and then straightened, which is very labor-intensive.

In addition, arrow shaft polishing is also a major part of the work. It is called "pull rod". It uses a special tool to polish the original square arrow shaft into a round shape. It is divided into two times, one rough polishing and one fine polishing. There must be a day's interval between two times to allow the wood to adapt so that it does not deform...

Another point is that when processing arrow shafts, the weight of each arrow shaft must be basically consistent. Otherwise, the previous arrow will be extremely heavy and the next arrow will be light. It would be strange for the archer not to curse...

After listening to Huang Chengyan's explanation, Fei Qian realized why Huang Chengyan's words were a coincidence. Without a large number of skilled craftsmen, it would not be an easy task to make arrows that meet the standards...

Although ordinary arrows customized in the military do not require too many exquisite things, after all, there is too much manual work and it consumes a lot of time...

And this thing is a consumable item. Although it can be recycled, it is also easy to damage... No wonder it is calculated in tens of thousands. In Fei Qian's impression, how much did Zhuge Cao Chuan steal in one go by borrowing arrows?

Those who were still stuck on the boat, and more who were not hit fell into the water...

Is there any way to simplify it...
