The famous gold and jade craftsman Zhijian lived in Jinling for generations. He was a famous jade craftsman for many generations. The jewelry he produced was loved by many celebrities and nobles.
Because of his great reputation, he was later targeted by interested people. A wealthy family in Nanjing asked him to make a few small items from Hotan. Strangely enough, these small items were not for the living, but jade plugs used by the dead. , specifically to plug the old friend’s five orifices.
The gold and jade craftsman does not compromise on his work, let alone cut corners, but someone changed the package and made one of the jade plugs into the old turtle's soul-soothing piece. It is said that this thing is used to calm the soul, so that the dead will not be reincarnated. At this time, the boss in Jinling City was able to directly unite with the big officials in the city and destroy the entire Jin family.
The gold and jade craftsman had no choice but to go into exile alone, and kept coming to the south. The south was relatively peaceful and the people were kinder, and finally he met Liang Chuan.
Following Liang Chuan's instructions, the gold and jade craftsmen quickly produced the lenses Liang Chuan wanted.
The purity of these two pieces of crystal is quite high. After careful work by gold and jade craftsmen day and night, they are like products produced by machine-standard flow lines, with excellent transparency.
There was an arc around the bulge in the middle. Liang Chuan took the crystal polished by the jade craftsman, and his excitement was indescribable.
Liang Chuan brought the crystal up to his nose and took a closer look. There were many scratches on the crystal that were thinner than cow hair. The lines were all in the same direction. They were clearly the marks of manual polishing.
Since the Warring States Period, there have been many crystal products. After many treasures were discovered, experts would identify them and see the polishing marks on the crystal cups. If they are old, they will definitely only have a smooth side and no traces of artificial time.
"How did you make this crystal so translucent? How did you polish it?"
The gold and jade craftsman smiled. Liang Chuan thought that this was also a trade secret, so he said, "If you don't want to say it, I won't force you!"
"There is nothing magical about this. They smelted iron and produced a lot of iron powder. They added water to make a coarse paste and ground it. Finally, they rubbed it with musk deer skin and it became pure and translucent!"
Liang Chuan nodded.
"At first, I was worried that there wouldn't be enough materials. Our island has more supplies than I imagined. One day's work is enough!"
"Master Jin, please continue polishing the other piece. I'll use this piece first!"
Liang Chuan took away the first piece of crystal ground by the goldsmith and called out An Yisheng and Secretary Huang.
The sun was at its highest, shining warmly on me, but the sea breeze still made me feel a little chilly.
"Uncle Master, this is today..."
"Let me show you something good. If you have any paper on hand, help me get one!"
"What paper? Straw paper?"
Liang Chuan rolled his eyes at Secretary Huang and said, "That's okay!"
Secretary Huang took out a piece of straw paper. Liang Chuan placed the paper on the ground and took out the crystal lens. The sunlight passed through the lens and focused on the paper. Liang Chuan playfully adjusted the height to concentrate all the light at one point.
The two of them stared at Liang Chuan's movements, wondering what Liang Chuan was doing.
The two of them were not blind. They saw that the piece of papyrus on the ground began to turn black and smoke after being exposed to the bright sunlight for a period of time, and then it actually burned!
"I only know that in ancient times, the Suiren clan had a way of making fire.

Magic skills, you. . Uncle Master, you. . "
An Yisheng stuttered when he spoke. Although the skill of making fire with a magnifying glass was not worth mentioning to the primary school students of later generations, they did not know the principle and thought it was just a skill of heaven and man. Seeing it from Liang Chuan's hands, they were still shocked. They cannot be added.
Secretary Huang also said: "The little Heavenly Master can call the wind and rain, and you can control fire. Your Longhu Mountain is indeed mysterious!"
The smile on Liang Chuan's face gradually solidified. He was originally going to popularize science and technology to the two of them, but now it's better. If the performance continues, the two of them will only believe that they only have magic skills, let alone learn the so-called science!
"This lens is called a convex lens. This lens can change the refraction angle of light. The sunlight passes through this crystal and concentrates the light together, so it burns. The fire control technique you are talking about is not that evil!"
Before the two people could react, Liang Chuan took them to a stone and used the lens to find things on the stone.
"You two use this lens to take a look and see if you find anything!"
Secretary Huang took the lens and looked at it on the stone. Suddenly, he found that the objects in the lens seemed to be magnified. The ants on the stone seemed to have grown bigger. They were only half the size of a grain of rice, but now they are half the size of a finger. Suddenly Secretary Huang was shocked by the change. He took the lenses away and looked down. The ants were so small that they were still hard to find!
Move the lens back again, and the ant instantly becomes bigger again!
"What a magic mirror! Lao An, take a look!"
One lens made two people feel as if they had discovered a new world. After receiving the lens, the two of them kept looking at it and marveling at it.
"What kind of magic mirror is that? This thing is very useful. If someone's eyes are not working well and can't see the things in front of them clearly, if they are made into glasses, they can restore the bright and clear world! I will go back and ask the gold and jade craftsman to polish it again. "
Secretary Huang said: "That is the problem of scholars. They read too much when they were young, and they suffer from eye diseases when they are old. There is a joke, a farmer passed by carrying dung, and a short-sighted man thought he was selling shrimp paste. He called "shrimp paste, come here", but the farmer didn't know how to call him and ignored him. The blind man was furious, rushed up and grabbed a handful of dung from the basket, put it under his nose and smelled it, and said angrily: "You This shrimp paste stinks, why do you think it is a rare commodity, and still have such a market price? "
Liang Chuan was amused by him and said: "We have such a lens in our eyes, but it is very small and subtle, you can't see it. When you are old, do you still have an eye problem, that is, you can't see words when you put them up close? Only when you look far away can you see it clearly!"
The two of them said solemnly: "Exactly, I, Lao Huang, am fine, but Lao An's illness is a bit serious. His handwriting looks like mosquitoes peeing and urinating, and it is completely difficult to see clearly. I have to write it bigger!"
"We have been suffering from this disease for many years. Do you still have the skills to remove the turbidity and restore the vision?"
Liang Chuan waved his hands and said: "There is no way to remove turbidity and restore sight. To put it bluntly, the curvature adjustment function of this small lens in our eyes has deteriorated. We have to use external lenses to readjust the curvature of our eyes. , but the lens is not a convex lens, but a concave lens that makes the object smaller!"
Upon hearing this, the two of them immediately cast a fiery and longing look, and said to Liang Chuan: "Master... are you still here?"
(This chapter is not finished, please turn the page)
There is such a treasure. . Can you let us see it? "
Liang Chuan said: "I will ask the gold and jade craftsman to polish two more lenses, you just need to wait for two more days!"
For two days, the two elderly doctors waited anxiously. Although they didn't have this name for presbyopia yet, they collectively called it eye disease. It's just that people are different. The old scholar couldn't read small prints clearly when he got older, and some people... You can see it so clearly, but the cause of the disease is not clear at all!
What both of them know is that this disease is so annoying, especially the elderly who are unfriendly, as if they are blind, and are particularly prone to falling. It is also very easy to make jokes. For example, three brothers who are all short-sighted went to visit a family together. There was a plaque on the main hall of the host's house that read "Yi Qing Tang". The boss looked at it for a long time and said, "Oh, it turns out that the master has this disease. Look at the 'Yi Qing Tang' hanging on the hall." The second child said Said: "Don't talk nonsense, the master is obviously good at Taoism, but the one he is talking about is 'Daoqingtang'." The two couldn't argue and asked the third child to judge, but the third child said: "You two are talking nonsense. Where is the plaque in this hall?"
There is no magic in the world that can restore sight after loss, but Liang Chuan can only rely on a small stone to make his eyes see the Qing world again. Isn't that a miraculous skill?
Two days later, Liang Chuan placed two convex lenses and two concave lenses in front of the two doctors.
"Is this a concave lens?" Secretary Huang looked at the lens and wanted to touch it but didn't dare. In his opinion, the lens looked more like a mirror for looking at demons!
"Dr. An, pick up these two concave lenses and try to see if the ants on the ground can see clearly!"
An Yi was born with presbyopia. He could see clearly in the distance, but he was blind when he saw near. He put two lenses in front of his eyes, one on the left and one on the right. The world that was a little blurry in front of his eyes suddenly became clear. Mountains are mountains and rivers are water, and the sea surface is It was so magnificent that you could even see the ants on the ground so clearly. It was just like when I was young, such a refreshing feeling!
"This... this is incredible!" An Yisheng was so excited that he was about to shed tears. He devoted his life to various diseases, but doctors cannot treat themselves. Even Secretary Huang was unable to do anything about their own eye diseases. Liang Chuan said three times , cured this disease with two broken stones?
If he couldn't understand the gods before, he couldn't understand how they prayed for rain or how they called for wind, but he still couldn't understand this stone?
This is obviously a method they don't understand, not some heavenly technique!
Is this what Liang Chuan calls knowledge?
He was dazzled for a third of the time, and the intellectual building he had learned and built throughout his life seemed to collapse at this moment. .
Liang Chuan said: "This lens still needs a frame. It can be worn on the head all the time without falling off!"
An Yisheng was a little excited when he heard this. Doesn't this mean that he will no longer have to suffer from eye diseases in the future? The two stones also have a so-called frame. This has a great impact on their medical skills. It turns out that this is how to treat diseases. Can the disease be cured directly if it injures the body skin?
"Give me a few more days, and I'll show you a more shocking microscopic world!"
You two look at me and I look at you, what could be more shocking? Liang Chuan seems to be doing the opposite of the technique they have been studying all this time. Whether it is the artillery or the lens, it is more like a physical thing. Is it possible that the end of medical skills is to work on this?
