Chapter 394: Turning Stone into Gold
Qingyun listened with a frown, suddenly interrupted Junzhi's introduction, and raised his own doubts, "Although the idea of ​​absolute precision is very good, absolute precision does not exist where human errors can occur. Although this crossbow The design takes into account so many variables, but at least one premise must be guaranteed, that is, the person who uses the crossbow must hold the crossbow absolutely horizontally, otherwise the compensation in the directions of up, down, left, and right will be biased. The more accurate the revision, the greater the actual error. Outrageous. In fact, it's impossible."

Mr. Huayang had been absent-mindedly checking today's dinner dishes, when he suddenly heard Qingyun mention the level positioning, he immediately hummed, "You are talented! You are indeed talented! Now I am starting to regret that I didn't accept you as an apprentice Well, tell him about it."

Back then, when Qingyun asked Mr. Huayang for Zixia Gong, he had intended to worship him as his teacher, but Mr. Huayang didn't want to take advantage of Qingyun Tangjun's status.Therefore, he did not agree, but Huayang did not hide anything from Qingyun. Whether it was the tricks of swordsmanship, the secret technique of qigong operation, or the introduction to psychology, as long as Qingyun was interested, Tao Hongjing would teach him everything. .

Li Zhi lamented that the master was a bit off-centered, shrugged, and continued to explain to Qingyun: "There is actually a level design in this scope. The reason why the level is called level is because the water surface must be flat. So if you look carefully On the upper part of the scope, there is a small liquid sac screwed inside, which is made of a very small fish float. The color is transparent, and the liquid level in it can be clearly observed. There is also a scale on the lens at the front of the liquid sac. As long as the sight is installed in place, this scale line represents the level. Comparing the liquid level of the liquid bladder with the scale line, you can ensure the absolute level of the crossbow. Considering that the liquid will continue to melt, this liquid bladder can be filled repeatedly or alternatives."

"Oops, perfect!"

Since it has been done so elegantly, what else can be picky?

Now there is only one question left for him, what is that water gun used for?
"Do you still want to know the purpose of this?" He Zhi took out the three-foot-long side-by-side bamboo tubes.

Qingyun and Liu Ying nodded one after another. Although the latter can only listen to a half-knowledge, is there any man who has no interest in weapons at all?Especially for a man who is so addicted to swords like a demon, especially for such a mysterious weapon.

"There are still several problems in the complete form of this crossbow. The first is the crossbow arrow, which you already know. According to our preliminary estimation, the weight of the arrow should not exceed half of the ordinary feather arrow. Although the volume of the arrow is much smaller than Arrows, but because we need to use the absolute unity of the metal retainer type, the current hardware cannot meet it. So we hope to solve this problem through thunder lead.

The second is the crossbow string.Even if the weight of the arrow is only half that of the feather arrow, to send them a distance of [-] steps requires great tension.We haven't found a suitable material yet.I heard that Dijiang's tendons can heal..."

"Dijiang? The Dijiang in Tianshan Mountain?" Qingyun couldn't hide his excitement when he heard something extraordinary again.

"Don't interrupt, let the second brother talk." Liu Ying said dissatisfied.

Tinzhi didn't care much, smiled, and continued, "We can only put aside the matter of the bowstring at the moment. But we have set up such a bowstring, so we have to consider how to pull it. After the teacher and I Calculated, if an adult male wants to pull the bowstring, even if he uses all his waist strength, he can't do it. If he doesn't find a way to open the crossbow, this thing still can't be used normally.

So, Master and I made this winding device again.It consists of two bamboo tubes, one thick and one thin.Fill the straw with water before use.Then we pull the bolting device to press the water in the thin tube into the thick tube. Without much effort, we can push the bolting device on the side of the thick tube by a section, even if the thick tube is hooked with a strong crossbow string.We then use this mechanism to put the water back into the thin tube and press the second section of the thick tube again.The ingenuity of this is mainly in the connecting water pipe between the bolting device of the thick pipe and the bamboo pipe. It is necessary to switch the outlet of the water pipe every time a section is pushed.

Although it is complicated to say, in actual use, as long as it is pulled back and forth like this twelve times, one winding can be completed. "

After saying that, he pulled up the horizontal bolt on the thin tube and pulled it back and forth twelve times.Sure enough, the pegs on the thick pipes also began to move.

The stroke of the thin rod bolt is very long, and it needs to be pulled more than three feet every time it reciprocates, but after twelve times, the thick pipe bolt only moves about one foot.

Liu Ying seemed to be a little puzzled, "Isn't it just a bolt, what are you doing so hard for?"

Jizhi frowned and replied, "Why can't I explain to you? In this way, you and the fifth brother grab the thick bolt here, hold it tightly, and don't let it move! But don't use internal force, be careful Destroy my crossbow machine! See if you can hold him back."

It was within Qing Yun's expectation that Dian Zhi fought against the two with his own strength and won easily.He had seen this method of using different liquid surface areas of the container to amplify the power in Zu's Stargazing Pavilion.

There is only one question he cares about now, "Will this thing be ugly when it is finally assembled?"

Jizhi was in a hurry at that time, he is a perfectionist in terms of engineering design!
"How come, I'll pretend to show you on the spot!"

The three-foot-long winder and crossbow were assembled, and he raised his hands horizontally, put the ends on his shoulders, and aimed with one eye.Then began to repeat the action of pulling the bolt and winding the string... That style is very similar to the sniper rifle of later generations...

Fortunately, there are no traversers here...

However, if this crossbow is really equipped with strings and arrows, and can aim at the target within [-] steps, it will be a good example...

How is this different from a sniper rifle?

Mr. Huayang predicted that such a weapon might change the way of war before it was fully developed. This is the great wisdom of foresight!

"Perfect!", this time it was a compliment from martial idiot Liu Ying.

This is the best affirmation of a martial idiot to a divine weapon.

"There are still some small flaws." Tunzhi said sincerely, "Our design concept is to kill with one hit. But the arrow made of lead rod has too small hit point, if it is not shot at the fatal place, it will still Not enough to make the opponent lose combat power. The reloading of this crossbow is very slow, and if it misses a hit, the opponent will have defenses. This is a slight flaw."

"Wipe the poison!", Liu Ying's proposal was simple and rude, but Junzhi didn't take it seriously.

As a perfectionist designer, poison is the next choice.

Because poison is a double-edged sword, it also has great potential danger for users.

"I have a proposal!" Qingyun spoke this time.

"""""Knock on the blackboard time"""""

The first one to explain is the one who is the most interesting~
What is the concept of the difference of about three inches between the peak and the valley of Miss Mochou?
As mentioned earlier, one foot in the Southern Dynasty was about 25.8cm, and three inches was 7.74cm.A bust measurement without the key points is the under bust, and a bust measurement through the key areas is the upper bust.The difference between the two is about 2.4 times the peak-to-valley value (the geometric increment is two arcs with the peak-to-valley value as a half-chord).

Therefore, we can roughly obtain that the difference between the upper and lower bust is about 18cm.That is exactly D-cup.

Alchemy, we have probably talked about it in the previous article.

People with a little knowledge of chemistry and physics should know that it is absolutely impossible to play so many tricks with lead salts and mercury salts, so the ancient art of lead and mercury refers to solid metal (lead) and its salts, liquid Metals (mercury) and their salts.

Lead, "Shuowen" calls it green gold, "Jade Pian" calls it black tin, and "Zheng Zi Tong" says that it often coexists with silver mines in Shu County. "On Treasures" has the most comprehensive summary. There are several kinds of lead, and the Persian lead is hard and white, which is the first.It can be clearly seen from the above that lead belongs to a different metal, silver, and there is no silver-bearing lead mine in Shu County, but only in Yanbian.

Mercury, also known as mercury, means liquid silver (metal).

So this is the correct meaning of the way of lead and mercury.

In the same way, the technique of air green (mainly composed of basic copper carbonate) turning stone into gold has been recorded in many books. It is mentioned in "Zhouyi Cantongqi", but it is not mentioned in detail. It is recorded in the "Compendium of Materia Medica", and the text has been included, indicating that this method is to use empty green to turn lead and copper into gold.

Many medical books have since endorsed this article.

"Bielu of Famous Doctors": Smoked copper essence will produce empty blue, and its abdomen will be hollow. (This shows the relationship between the ancient way of empty bluestone and copper)
"Compendium of Materia Medica" (Tao Hongjing): Kongqing, Yuesong belongs to Yizhou, and the ones that come out of bronze officials today have the freshest and deepest color, and the ones that came out of Shixing are Furu. There will be no more in Yizhou counties, and I'm afraid they won't be picked for a long time Therefore also.There are many green mountains in Xiping County, Liangzhou.Now the sky is green but round and solid like iron beads, and those who have no empty stomach are all taken from earth and stones.Also, if it is combined with pills, if it succeeds, it will turn lawsuits into gold.Among all stone medicines, this is the most expensive, and it is rarely used in medical prescriptions. (Mr. Tao pointed out the relationship between empty bluestone and alchemy, and then explained that empty bluestone itself is not cheap and is rarely used in prescriptions.)
"Compendium of Materia Medica" quotes "Gengxin Jade Book": clouds, empty blue, and cloudy stones.Produced in Shangrao, the one that resembles stalactites is the best, with large patches of purple color and luster.The second time it came out of Yandao of Shu and the mountains of Beidai, it grows in the golden ridge, and the life is endless, so the green is the pill, which is as big as a fist and oval, with water like oil in the hollow, and it is effective for curing blindness.Those who come out of the copper pit are also good, and they are suitable for painting. There are Yangmeiqing and Shiqing, all of which are integrated, and the energy is refined and rough. Zengqing is the first to enlighten, followed by Kongqing, followed by Yangmeiqing. (This text record involves ore dressing. Kongqing is a hollow ore, Zengqing is a mica-like cyan ore, and Yangmeiqing is a garnet-shaped ore shaped like a bayberry.)

To sum up, these books all point out that the metal component in the sky is actually copper, and then point out brass by turning lead and copper into gold.This is the so-called Midas touch.The lead used to refine brass is zinc.Because brass is a lead-zinc alloy.

These language teachers are difficult to figure out, and chemistry teachers seldom study ancient Chinese, which has resulted in many very clear records in ancient times not corresponding to modern languages, making the truth sink in the blue slips.

In order to speed up the progress of the update, the future knocking on the blackboard section will be shortened as much as possible.We will put the content of knocking on the blackboard in the next section about the modern explanation of ghost hair lead (nickel), ancient zinc production (Japanese lead), thunderbolt method, Dingqin sword, and crossbow machine.
