The red-hot and softened glass is cut by a craftsman with large scissors and dripped into a mold, which is then pressed into shape by another mold.

When it cools, it will naturally become a convex or concave mirror that the craftsman needs.

"This look can't be used yet, the shape is rough, and it depends on the craftsmanship of the craftsman later." Xu Lu'an took Chen Mu and the three of them outside, rolled up his sleeves, and pointed to the craftsman working outside and introduced: "That's called sand fishing, and the sand is a special trip from Shuntian Yutian and Zhending Xingtai to solve the jade sand. ”

"The sand has a size and thickness, and the sand that is pounded and milled is washed and precipitated, and the natural light ones sink in the heavy ones, and the coarse sand is used for cutting; Polishing with fine sand. ”

It seems that Xu Lu'an is planning to demonstrate it to a few people in person, and there is no doubt that he is the best craftsman here.

Chen Mu is more interested in the various manpower and machinery placed in the open space outside the factory than how to sharpen the glass, such as the iron basin that turns the sand, and the other iron disc is connected to the bottom, and the craftsman steps on the basin above the disc to rotate, and the craftsman uses it to cut the jade with sand.

The sand they use is jade sand, Chen Mu has seen it, and the sand that can be seen everywhere is different, the biggest difference is hard, these sand will be sharpened again due to the section after being mixed with water and grinding jade, according to Xu Lu'an, such sand can be used by a craftsman for a lifetime in the past.

But now the production volume is large, and the continuous production has caused the loss of the jade sand, and the next time there is a ship back to Daming, he will buy another batch of the jade sand.

Xu Lu'an introduced to the three of them while grinding the mirror: "In the past, the process of tapping jade was complicated, cutting, drilling, carving, piercing, and polishing. ”

"The process is simple, some craftsmen are also lazy, in the coarse grinding to make the grinding effortless, grinding out the appearance is not bad, but I still like to grind, although it is slower, but the work is meticulous."

Xu Lu'an said that the grinding machine is fixed on the table, the center of the round grinding mirror stone on the table has a long rod on the other side of the shelf, there are several circles of rope on the rod, and the two pedals are connected when they fall, and the craftsman's feet step on the two pedals alternately, and the round lump of the grinding mirror stone rotates in a semicircle, and the craftsman sharpens the lens from it, which is more efficient.

Xu Lu'an stubbornly grinded the mirror with his hand, causing Chen Mu to laugh, which has nothing to do with meticulous work, it's just that his family craftsman is more old-fashioned.

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

But it wasn't until Xu Lu'an really started grinding that Chen Mu understood why Xu Lu'an said that hand grinding was meticulous, because the abrasives used for coarse grinding are different from those used for fine grinding, and the coarse grinding of the jade sand is coarser and more profitable, so it grinds faster.

On the contrary, when the grinding time is used, the grinding time is longer because of the change of finer and slightly softer abrasives.

It took a long time to sharpen the lenses, Chen Mu and the three of them watched Xu Lu'an's repeated movements gradually disappear, and it was natural to talk about the subsequent purpose, Chen Mu said: "With this, you can magnify things that cannot be seen with the naked eye, what do you think is the reason why people get sick, such as West Guy disease?" ”

Hearing that Chen Mu gave the bayberry sores another name, Chen Shigong was really stunned, and then said very firmly: "Evil spirit." ”

Chen Mu tilted his ears.

Chen Shigong continued: "Infected Yang, there are two common causes of Kinkey disease, one is gasification, that is, from the mouth and nose, the evil qi attacks the spleen and lungs, the infection is mild, the patients have no contact with the patient, how the evil poison enters the body is not clear, but they all accurately remember that they contracted this disease after going to the toilet, this kind of patient is few, the evil qi is also weak, and it is easy to cure. ”

"The second is refinement, mostly caused by ** uncleanness, attacking the bone marrow, and poisoning the liver and kidneys."

Chen Shigong said and frowned, and said: "However, from the observation below, there can also be a third kind, the cause is not yet known, maybe the evil qi has already entered the body, the body has no appearance, and the person does not know, then the husband and wife are dyed together, if the reproduction is misbehaving, then the second dye, the third dye, the fourth, it is impossible to prevent it." ”

"The Yellow Emperor's Neijing" talks about the origin of all diseases, saying that people's illness is due to the invasion of external evils such as wind, rain, cold, heat, clearing, and dampness, as well as emotions such as joy and anger that hurt the internal organs, but strong people can resist even if they encounter the six evils."

Chen Mu nodded slowly, although this statement is quite idealistic, it is also very great.

This is a set of disease theories based on the code name of yin and yang, the five elements, the five plagues, and the six evils through empirical theories when all means cannot be verified, which is very powerful.

Chen Mu knew that it was bacteria, a virus, and an invisible little creature that burrowed into your body and fought with your guards, but Chen Shigong and the doctors for thousands of years didn't know.

Because I didn't know, I put forward a hypothesis and put this hypothesis into practice, and improved the discipline with the experience of generations of doctors.

It's amazing.

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

Chen Shigong said with a smile: "Qi Bo said that if people are too worried and worried, their hearts will be injured, and the external cold and evil spirits, coupled with cold diet, will hurt the lungs; If the anger is excessive, the liver is injured; If you have sexual intercourse after being drunk, sweat and receive wind, your spleen will be injured; Excessive exertion, or sweating in water after intercourse, can cause kidney injury. ”

"People do have such problems, but there is no way to verify whether the five organs are really injured." Chen Shigong seemed to want to say something, but he paused again, and asked instead: "The marshal is waiting for this matter, I want to go to France to have a look." ”

As soon as Chen Mu wanted to ask, he already realized why Chen Shigong wanted to go to France.

That is at war, and there are dead people at war.

Chen Mu waved his hand and said: "You don't have to go, the Nine Classics have a doctor, they will also do these things over there, and there will be a report back in a few days, you just need to summarize it and study it." ”

"I think these diseases should be small creatures, just as elephants are big and mayflies are small, there should be creatures smaller than mayflies in the world, but it is difficult for us and other mortals to see, these little monsters are born in heaven and earth, just like you said evil spirits, once people's bodies are invaded by them, they will multiply and grow, and people will be weakened."

"And if there is a thing in the world, we will first find a way to find these little things, and then find a medicine that can kill them without harming the human body, and then we can cure the disease." Chen Mu said eloquently: "Even the medicine is the same, the herb is tormented, what is boiled on its body to kill the germs?" If we collect more things that can kill germs, will the medicine be more effective in eliminating the disease? ”

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

As they spoke, Xu Lu'an had already carried out the process to the end, the finely ground lenses were translucent and rough, and the craftsmen were polishing them with leather and oil until they made them bright and transparent, and then wrapped them in cowhide.

Chen Mu held it in his hand, there was no scratch on it, the arc was even, the perspective was good, and it was almost perfect.

"It's such a lens, a set of three, all lenses are the same size, the thickness of the arc is different, do more." Saying that, Chen Mu raised his hand and said to Xu Lu'an: "Do this well, and you will be able to go down in history!" ”/14_14088/
