Chapter 1094 Six Evils
The red-hot and softened glass is cut and dropped into the mold by the craftsman with large scissors, and then pressed into shape by another mold.

When it cools down, it will naturally become a convex or concave mirror that craftsmen need.

"This shape is not usable yet, and the shape is rough. It will depend on the craftsmanship of the craftsman." Xu Lu'an took Chen Mu and the three outside, rolled up his sleeves, and pointed to the craftsman working outside. Shuntian Yutian and Zhending Xingtai transported Xie Yusha."

"Sand has different sizes and thicknesses. The pounded and milled sand is used for elutriation and sedimentation. The lighter ones sink on top of the heavier ones. Coarse sand is used for cutting and fine sand is used for polishing."

It seems that Xu Lu'an intends to demonstrate it to a few people by himself. There is no doubt that he is the best craftsman here.

Compared with how to sharpen glass, Chen Mu is more interested in the various human-powered machines placed in the open space outside the factory, such as an iron basin for turning sand, with another iron disc underneath, and the craftsman steps on the basin on the disc to turn it , Craftsmen use it to cut jade with sand.

The sand they use is Jieyu sand. Chen Mu has seen it. It is different from the sand that can be seen everywhere. The biggest difference is that it is hard. The sand will be sharpened again because of the section after it is mixed with water. According to Xu Luan, In the past, such sand could be used by a craftsman for a lifetime.

But now the production volume is large, and the continuous production has caused the loss of Xie Yusha. When the next ship returns to Daming, he will buy another batch of Xie Yusha.

Xu Luan introduced to the three people while grinding the mirror: "In the past, the process of tapping jade was complicated, including cutting, drilling, carving, piercing, and polishing. polishing."

"The process is simple, and some craftsmen are lazy. It is effortless to make the weight in the rough grinding, and the appearance is not bad, but I still like to grind by hand. Although it is slower, the work is meticulous."

What Xu Luan mentioned is a grinding machine fixed on the table. There is a long pole in the center of the round mirror stone placed vertically on the table, which is placed on the shelf on the other side. There is only one pedal, and the craftsman's feet alternately step on the two pedals one after another, and the round mirror stone will rotate in a semicircle, and the craftsman can sharpen the lens from it, which is more efficient.

Xu Lu'an stubbornly rubbed the mirror with his hands, making Chen Mu laugh. This has nothing to do with meticulous workmanship, but his master craftsman is more old-fashioned.

If it is said that the work is meticulous, then an excellent skilled jeweler is also very skilled in using the machine, not to mention that you still need to use a hammer for fine grinding?

But it wasn't until Xu Lu'an really started grinding that Chen Mu understood why Xu Lu'an said that the hand grinder was meticulous, because the abrasives used for coarse grinding and fine grinding are different, and the rough grinding Jieyu sand is coarser and sharper, so it grinds faster.

On the contrary, when the ram is used, the grinding time is longer because of the finer and softer abrasive.

It took a long time to sharpen the lenses. The three of Chen Mu watched Xu Luan's patience in repeated movements gradually disappear, and it was natural to talk about the purpose afterwards. Chen Mu said: "With this, you can magnify things that are invisible to the naked eye. What's the reason, like Xie Lao disease?"

Hearing that Chen Mu named Yang Meishao again, Chen Shigong was really taken aback, and then said very firmly: "Evil Qi."

Chen Mu tilted his ears.

Chen Shigong continued: "There are two common causes of infection with Yang and Xilao disease. One is qi transformation, that is, it is infected from the mouth and nose, and the evil energy invades the spleen and lungs. The infection is relatively mild. Most patients have no contact with the patient. It is not clear how the poison entered the body, but they all accurately remembered contracting the disease after going to the toilet. This kind of patient is rare, the evil spirit is weak, and it is easy to cure."

"The second attack into the bone marrow is poisoning of the liver and kidney."

Chen Shigong frowned and said: "However, from the observation below, there may be a third type, the cause of which is not yet known, maybe the evil energy has already entered the body, there is no external appearance in the body, and people don't know it. Three, three and four, it's impossible to guard against."

"The Yellow Emperor's Canon of Internal Medicine talks about the beginning of all diseases, saying that people's illnesses are caused by the invasion of wind, rain, cold, heat, clearness, dampness and other external evils, as well as the damage of internal organs by emotions such as joy and anger. It can also resist the six evils."

Chen Mu nodded slowly. Although this statement is idealistic, it is also great.

This is a set of disease theories based on yin and yang, five elements, five epidemics, and six evils created through empirical theory when all means cannot be verified. This is very powerful.

Chen Mu knew that they were bacteria, viruses, small invisible creatures that got into your body and fought with your guards, but Chen Shigong and the doctors for thousands of years didn't know.

Just because I don't know, I put forward a conjecture hypothesis, put this hypothesis into practice, and use the accumulated experience of doctors from generation to generation to perfect this discipline.

Great.

"What is the emotional injury mentioned in the book?"

Chen Shigong said with a smile: "Qi Bo said that people's worries and thoughts are too much, and the heart will be injured; exogenous cold pathogens combined with cold diet will damage the lungs; excessive resentment and anger will damage the liver;"

"People do have such problems, but they can't verify whether the five internal organs are really injured." Chen Shigong seemed to want to say something, but then paused, and asked: "The commander-in-chief is here, I want to go to France to see .”

Just as Chen Mu was about to ask a question, he already realized why Chen Shigong wanted to go to France.

Then there is war, and there are dead people in war.

Chen Mu waved his hand and said, "You don't need to go. The Nine Classics brought the doctors, and they will do these things over there. A report will come back in a few days. You just need to collect it in one place and study it."

"I think these diseases should be small living things, just like elephants are big but mayflies are small. There must be creatures smaller than mayflies in the world, but it is difficult for me to see them with naked eyes. These little monsters are born in the world, just like you said Once the human body is invaded by them, they will multiply and grow, and the person will become weak."

"In the world, one thing is one thing, we should find a way to find these little things first, and then look for medicines that can kill them without harming the human body. The medicine will cure the disease." Chen Mu talked eloquently: "Even The same is true for medicines. The torment of herbs means that what is boiled out of them can kill germs? If we collect more things that can kill germs, will the medicine be more effective in curing diseases? "

"It all needs a premise, and we can see them."

While they were talking, Xu Lu'an had finished the process to the end. The finely ground lens was a translucent rough surface. The craftsman was polishing it with leather and oil until it was made into a bright and transparent lens. The cowhide bag was brought over.

Chen Mu held it in his hand, without a single scratch on it, the curvature was even and the perspective was good, almost perfect.

"It's just like this lens, three sets, all the lenses are equal in size and thickness, and the curvature is different, make more." Chen Mu raised his hand and said to Xu Lu'an: "If you do this well, you will be famous in history !"
