After getting glasses, Shen Kuo felt for the first time that his eyes were no longer a burden to him. His waist suddenly straightened up, and his energy and energy were also lifted, and he immediately became different!
There seemed to be light in his eyes!
Even Ling Hu, who was closest to Shen Kuo, noticed the slight change in this boy's temperament and couldn't help but take a second look.
'What's this thing called?
Shen Kuo was a little excited.
He was not excited that he had regained his sight, but he was excited about the miraculous ability of this artifact, which actually restored his eye disease!
It was just two pieces of glass. He had also visited Jin Zhijian's workshop. He never expected that the thing right in front of him could solve the problem that he had been unable to overcome for many years!
'It's called glasses.
Liang Chuan paused and said, "But this thing hasn't been completely calibrated yet. The glasses that suit everyone are different."
Look, Liang Chuan pointed to the concavity on the lens: "Some people have serious eye diseases and need a higher power, so the lenses need to be much thicker, but some people don't need it!" When you are adjusting Jin Zhijian, you need to let people feel it constantly. Only they themselves know best whether their eyes can see clearly!
Jin Zhijian responded, feeling extremely surprised. How could Liang Chuan know so many truths? He had played with jade all his life, but he didn't know anything about telescopes and glasses. .
Shen Kuo was extremely excited. From now on, he no longer needed to stick the book to his face to read, let alone chase after others to recognize them. .
Liang Chuan said to Jin Zhijian: "Are your eyes the opposite of Shen Kuo's? You can't see things when you hold them too close, but you can see them clearly when they are far away!"
Jin Zhijian was horrified, how could Liang Chuan even know what he was thinking!
Everyone was extremely surprised! Liang Chuan looked like a monster!
'Don't be surprised. This is a normal eye disease that everyone will suffer from. When you are old, your eyes cannot see clearly. This is called presbyopia. Shen Kuo, on the other hand, has myopia. He overused his eyes when he was young and used them up. He needs tools to assist him!
Jin Dajian was a little excited. Because of his eyes, he had seldom made these crystal objects by himself in recent years. He had only let his apprentices do it for him. For no other reason than that he had problems with his eyes.
Especially those small jade pieces, you can only keep them far away when carving, and you can't see them clearly at night, which is very distressing!
Jin Dajian quickly bent down to salute and said to Liang Chuan: "My boss, you have a great talent, please help me!" The old man's eyesight is dim, he has been suffering for a long time these years!
Liang Chuan held up the lens polished by Jin Zhijian and said, "You two have opposite eye problems. Shen Kuo can't see far away, and yours can't see close. What does that mean? Your eye diseases are mutually exclusive, so what?" This auxiliary lens also needs to be reversed!
Jin Zhijian was stunned and couldn't react for a moment.
Liang Chuan pointed to the depression in the middle of the lens and said, "Did you see it? This lens is sunken in the middle. If it is a lens that suits you, it should be convex in the middle, and the sides should be cut thinner!"
Jin Zhijian looked astonished!
'Let me try!
Liang Chuan gave the lens to Jin Zhijian, and Jin Zhijian turned and left excitedly. Being able to cure his eye disease is more important than anything else!
Liang Chuan hurriedly stopped Jin Zhijian and said, "Master Jin, don't be in a hurry!"
Everyone looked at Jin Zhijian and were filled with joy.
Jin Zhijian said: "My boss, do you have any more instructions?"
Liang Chuan still pointed to the small crystal and said: "Now you know that this crystal has three uses. It can be made into telescopes, myopia glasses, and reading glasses. Each has different uses, but I want to tell you!" This small lens, if you continue to study it carefully, will have greater uses!
Jin Zhijian and Shen Kuo were shocked.
'besides?
Liang Chuan said with a mysterious smile on his face: "Of course, don't look at this small lens. If played well, it can be extended to many novel objects. You should not carve those beautiful jade agates on the island. Study these carefully." Whether there will be a breakthrough in the future for this small crystal depends on Master Jin’s accomplishments!
Shen Kuo looked at his glasses carefully. The first time he was shocked was when he saw the artillery on the island. The huge power of destroying the world made him realize that human tools can be so powerful!
The second time, Liang Chuan gave him a small crystal piece. Such an inconspicuous thing, although it is also a precious jade and cannot be touched normally, but after polishing, the small jade can cure eye diseases without the need of a doctor. The wonderful prescription and good medicine are really the magic of gods and ghosts!
Is this the power of knowledge?
I have long heard Ling Hu talk about Liang Chuan. Liang Chuan never stayed in Shenji Camp, but he knew more about Shenji Camp than Ling Hu!
Everything on this island was caused by Liang Chuan!
A person's life is extremely limited. The limited time makes it difficult to learn so much knowledge!
How come Brother Liang Chuan can learn so much knowledge, and how come there is so much knowledge in the world, but he hasn’t even heard of it at all!
Humility made Shen Kuo become more cautious, and he became more in awe of Liangchuan and this mysterious island!
'I wonder if there is any difference in the purity of the crystal! Shen Kuo said curiously.
'Of course there is a difference!
Crystals these days are only natural crystals, artificial crystals cannot be found. The best thing for making lenses is not crystal, but glass, but these days glass is more precious than jade.
'To get better results, the higher the transparency of the crystal, the clearer you will naturally see.
Jin Zhijian said: "Exactly, the textures of crystals are different. Some are as clear as light, and some are turbid and mixed, and people can't be seen clearly." The lenses I make are all selected from thousands of sources, and the quality is very good!
At that time, the Oriental Abdullah sent countless ores to Liangchuan. These things were worthless in their eyes, but they were extremely precious here in Liangchuan. Liangchuan got the best iron ore from him and used these iron ores. He mined the mine and produced weapons and armors of excellent quality, which greatly increased the Liang Jiajun's combat power and obtained many crystals from him.
Crystals are at most considered decorations and jewelry in the hands of Eastern people. They are worth a lot of money when sold to the Central Plains. However, this trade route is not easy to open, and the merchants in the Central Plains are not stupid. Seeing the free crystals in their hands, If there are as many stones, they will understand what is going on. Then the price will naturally plummet, and they will not be willing to buy it at a high price.
In the end, Liang Chuan got the advantage.
It was with so many high-quality crystals that Jin Zhijian helped Liang Chuan make many telescopes. ..
It's a pity that Abdullah was not smart enough and colluded with the Pu family, and finally let Han Qi chop him into pieces.
If he is still here, continue to buy crystals from him. This thing will be of great use.
I heard that there are still Eastern merchants on the sea. Next time I meet them, I must continue to buy more from them.
'You are responsible for this matter. It seems that we need to set up an organization to manufacture glasses, telescopes and other objects!
Purchasing crystals is a very profitable business!
Even if it is raw crystal stones that are traded, most of them in Liangchuan only need to pay the cost of some low-grade raw materials. Crystals are jewelry and are sold at the price of luxury goods. A small piece of high-quality crystal can be sold for more than jade.
If it is made into high-end processed products such as telescopes and myopia, the price will increase hundreds and thousands of times. If you sell a pair to Bianjing, not to mention the market is not big enough. There are many dignitaries who want this thing, because their eyes There are so many diseases that these scholars
They are the people most troubled by eye diseases!
During the Ming Dynasty, glasses began to appear, but they were also the highest-end luxury goods. They were either rewarded by the emperor, paid tribute by foreign Tibetan people, or obtained from Hu merchants, and the cost was astronomical! The objects given by the emperor are treasures that can be passed down from generation to generation. The ministers' families must wear them and burn incense three times in the morning and evening. Ordinary people have no conditions to come into contact with such objects!
Liang Chuan had thought about it. When the time came, Sun Houpu would have Sun Houpu auction this kind of treasure in the Forbidden City. He would sell a few pairs a year. Each one should not be too expensive, just tens of thousands of guan. .
Seems a bit dark-hearted.
Now that the port is gone, economic pressure has suddenly increased, and Liangchuan has returned to the days of hard work! We must increase revenue and reduce expenditure, and think carefully about how we will live in the future!
Crystal is still not as useful as glass.
If you can make glass, it will be easy. You don’t need to buy any crystals. Glass can be made from sand. Before the market opens, you can make a lot of money on glass first!
The people on the island heard that Liang Chuan had come up with something new that could restore sight to the blind. It was said to be a treasure from heaven! The news quickly spread to Su Wei's ears. Over the years, as he got older, his eyesight gradually became harder to use, especially at night. He could hardly see at night, which seriously affected his work!
Hearing that Liang Chuan had a new treasure, he immediately chased after Liang Chuan, just to get glasses like this!
His problem is also presbyopia!
'You damn Liang Chuan, I've been working hard for you for so many years, but you've been hiding such a good treasure and not taking it out! Are you worthy of me?
Su Wei, a verbose little old man, usually nothing good can touch his heart. He doesn't like food, clothing, or anything else. He lives by his shabby life and feels at ease.
But when he encounters such a good treasure as reading glasses, even he starts to be tempted!
Putting on the reading glasses he just got from Jin Zhijian, the old man was so anxious that he wanted to attack Liang Chuan. Liang Chuan had such a treasure, but he was very angry!
'I really want to get you glasses, but look at how many times I've been at home over the years, I can't help myself!
Seeing me so happy, Liang Chuan was also very happy. There was finally some comfort in the loss of the past few days!
