Chapter 188 Glass ballast spectacle lenses are more expensive than gold

It will be a year since he came to the Tang Dynasty, and Jin Yu's understanding of this strange dynasty is obviously not enough. The pen "Fun" Pavilion www.biquge.info Take Chang'an as an example, he doesn't know where to polish the specified shape of Shuiyu. In the end, this problem still troubled Cheng Huaimo.

"Mizuyu? Who is the big brother going to jewell? This was Cheng Huaimo's first reaction, his face was obscene, and Jin Yu, who saw it, wanted to slap him twice.

"Give it to Huaiyu, why don't you call two too?" Jin Yu cooperated with Cheng Huaimo, and also looked ill-willed.

Cheng Huaimo swallowed a piece of ice like a cold winter moon, shivered, jumped to the side quickly, covered the chrysanthemum with his hand, and looked at this strange man who was called "big brother" by himself in surprise. "The little brother is not good at this, so the elder brother will spare the little brother! The younger brother congratulates the eldest brother and Huaiyu and his wife for their deep affection. Raise your eyebrows and ''''''"

"And the base is infinite, isn't it?" Jin Yu snorted coldly, grabbed Cheng Huaimo's head and talked about two brain collapses, this baby didn't know what to eat to grow up, the bones were hard, and Jin Yu's hands hurt.

"What so much nonsense? Tell me, where is it! Jin Yu shook his hand and had a bad attitude, but it was a little worse than Cheng Biting Jin.

"Junior brother, don't you want to cooperate with the eldest brother''''''" Cheng Huaimo saw that Jin Yu had a tendency to do it again, and hurriedly replied: "There is a treasure pavilion!" ”

"What are you doing? Take me along! Jin Yu glared at Cheng Huaimo, and seemed to have remembered all the wrongful ways he ran on Cheng Huaimo's head. In fact, it was also Jin Yu's negligence, and the Treasure Pavilion was originally to sell rare metals and shiny glass ballast that could attract NV people.

Cheng Huaimo was like an angry little daughter-in-law, and reluctantly took Jin Yu towards the Treasure Pavilion. It is said that the craftsmen of the Treasure Pavilion are the foundation of their own money, and only with good craftsmanship can there be more repeat customers, so the management of the craftsmen in the Treasure Pavilion is very strict, and Jin Yu may not be able to see people when he goes by himself. "What does Big Brother want to do?"

"Lenses, you don't understand it, it's better for you to learn a little bit when I tell the craftsman." Princess Changle is so smart and clever Lori, an ice convex lens consumes Jin Yu's tongue for half a day, Jin Yu doesn't expect Cheng Huaimo's understanding of this strange to be above Princess Changle, and it is better to go to the Treasure Pavilion to warm up on a cold day.

Cheng Huaimo nodded, stopped talking, and his mouth was cold.

The young master came, and the big shopkeeper of the Treasure Pavilion politely invited the two to the tea room.

"Jia is here?" After Cheng Huaimo entered the house, he took off his hat and gloves, wiped his face with both hands, and asked the shopkeeper of the Treasure Pavilion.

"Back to the young master, Jia Xianfeng is busy in the back, a few days ago a customer ordered two pieces of jewelry, which will be completed today." The treasurer replied respectfully.

"Let's go, let's see." Jin Woo stood up, tucked his hat and gloves under his armpits, and motioned for the treasurer of the Treasure Pavilion to lead the way.

"This ''''''" The treasurer hesitated, this is not in accordance with the rules? This year's craftsmanship pays attention to "passing on the inside but not outside, and passing on the children without passing on the NV", and the defense is strict.

"No this or that, lead the way!" Cheng Huaimo spoke, he really wasn't worried about Jin Yu stealing the teacher, what is Jin Yu's identity? Besides, he can exchange money for just a few things, will he care about this bit of craftsmanship? Taking a step back, this craft is not something that can be learned by a peek or two!

"I'm worried that Jia Xianfeng will not agree, and this son will forgive me." The shopkeeper of the Treasure Pavilion found a step for himself, arched his hand towards Jin Yu in embarrassment, and turned around to lead the way in front.

Jin Yu understood it as soon as he thought about it, and shook his head with a wry smile, he really can't blame others, they just do their jobs. Because he was afraid that Cheng Huaimo would slap his swollen face and become fat, Jin Yu opened his mouth to explain: "This thing I want is extraordinary, the technical requirements are quite high, it is better to communicate with Jia Xianfeng in person, and it will cost you a lot of effort and materials." ”

"The eldest brother is too worried, but the younger brother is not thinking too much." Cheng Huaimo explained with a grin.

When the shopkeeper of the Treasure Pavilion heard Cheng Huaimo say this, his demeanor became more respectful, and when he arrived at the mouth of the workshop, he knocked on the mén twice and said, "Jia Xianfeng, the young master sees that you are old." ”

"Just come, please wait a little bit." The man inside replied.

Cheng Huaimo explained to Jin Yu: "Jia said that if it wasn't for his father who saved his life, his old man would still not come." However, there are also some requirements, and it is a rule that you cannot enter without a permit. ”

"It's okay, I can't wait long." Jin Yu shook his head and didn't take it to heart, in these years, anyone who has a little ability can set his own code of conduct, or he won't be able to show his maverick, and he is still within the range that Jin Yu can bear. ,

In fact, Jia Laohan is very low-key, he is very clear about himself a few catties and a few taels, the reason why Cheng Biting Jin saved him at the beginning was also for the sake of his craft, if he refused the kindness of others, maybe he would have been buried in the loess. But then again, he is living a good life here, and his youngest sons have married wives and had children, which he didn't dare to think about before. However, this kind of good life is coming to an end, and I am getting older, although my kung fu is becoming more and more perfect, but my eyesight is no longer good, and it is getting more and more serious, if it weren't for the old foundation before, I wouldn't have been able to do it for a long time.

Jia Laohan dragged a piece of cloth to cover the guy who was eating, and went to open mén for Cheng Huaimo, for fear that the young head of the family would be blamed for being late. Even so, after Jia Laohan pushed Mén away, he still confessed first: "The old man is rude, Young Master Lao has been waiting for a long time, and it is warm in the house." ”

Cheng Huaimo nodded very generously, "Big brother, please first." ”

Cheng Huaimo's indifferent attitude towards the old man, Jin Yu didn't plan to point it out on the spot, no matter what aspect it is, this is his family matter. Accusing Cheng Huaimo in front of his subordinates would damage Cheng Huaimo's face, so Jin Yu also chose to remain silent and walked in.

It's warmer in the room, but it's darker. Since this work is a delicate job, there are candles lit in the house, and the surroundings of the illuminated workbench are as bright as day. It seems that it is not unreasonable that "glass slag" is expensive, and even this production workshop uses such exquisite materials, so it is strange that it is not expensive!

It's a great place to work! In the future, if you have your own leisure, you will also have to build your own laboratory. Jin Yu looked around and nodded with satisfaction before he explained his intention.

Jia Laohan has lived for most of his life, and he has seen all kinds of strange requirements, but Jin Yu's request this time makes him embarrassed, there is no room for independent play at all, and he must strictly follow Jin Yu's requirements, the spherical surface is smooth, natural, and round, which is quite difficult.

"Dare to ask how big is Childe's request?" Jia Laohan pondered for a while and asked.

Jin Yu heard Lao Jia ask, and with some confidence, he took out a piece of paper from his arms and put it on the table. Who says higher mathematics is useless? If it weren't for Jin Yu's high math skills, he really wouldn't have been able to calculate the profile!

"I drew a picture, and Jia Lao can follow the appearance of this picture, and the thickness of each part is marked above." Jin Yu pointed to a few lenses on the picture and said.

"The old man doesn't know the words on it, can the son read it to the old man?" Jia Laohan looked embarrassed, he was a distant relative of the Arabic numerals on it, and no one knew anyone.

Jin Yu patted his head, was negligent, and then told Jia Laohan one by one. Jin Yu adopts a node algorithm, there are several points on each lens, as long as these points are connected to make it smooth and round, then the lens is completed. Jin Yu converted all the units into the current market size, and it took a lot of effort for himself.

While Jin Yu was talking, Jia Laohan nodded, his brows kept furrowing, and he didn't stretch out. Jin Yu only remembered one thing after speaking, he didn't know if there was a vernier caliper this year! It's really hard to know if you don't. "What, is there anything to measure the thickness?"

"Yes, the old man showed it to his son." Jia Laohan nodded, turned around and lifted a small corner of the workbench, and took out a caliper from inside, although the appearance is a little simpler, but it is really the prototype of a vernier caliper! (In 1992, a copper vernier caliper was dug out of an ancient tomb in the early years of the Eastern Han Dynasty, and the wisdom of the ancient Chinese working people is infinite.) ）

"Yes, it's fine." Jin Yu took the caliper and played with it, it was different from that of later generations, there were no screws, and it was all pulled by hand, but it was also a great invention.

"The old man can give it a try." Jia Laohan understood the reason and was willing to give it a try. This thing doesn't seem difficult, but it's really not low-tech. A thick point is not a point, and a thin point is even more not. Three hundred and sixty lines, the line is the champion. As the leader of Zhuoyu's industry, Jia Laohan is unwilling to give up this opportunity to climb the peak of the industry.

"Done!" Jin Yu nodded, as long as he was willing to agree, he would like to make it, but this material still has its own requirements, "You must use a trace of impurities without transparent water!" Nothing with a sè is done, and it looks like it is the slightest bit from one side. ”

"This ''''''" Jia Laohan was embarrassed, he generally only accepts dispatches, and the issue of this material is really not under his jurisdiction.

Cheng Huaimo listened to it for a long time, he didn't think that Jin Yu was messing around, wasn't it jaw-dropping behind this big brother's nonsense? The layman looks at the lively, and the insider looks at the mén road. Zhuoyu's trip is a mén layman, but it is not! After following Jin Yu to learn arithmetic for more than a year, Cheng Huaimo sadly found that he couldn't understand the equations and calculation methods used by Jin Yu. As soon as the connoisseur made a move, he knew if there was one, Jin Yu made a move, and Cheng Huaimo felt that Jin Yu had a lot of goods in his stomach! As mentioned earlier, Cheng Huaimo's business talent is very high, and this time he subconsciously felt that it was profitable, so he also made a move. Cheng Huaimo instructed the shopkeeper standing aside: "Go and move all the transparent water in the warehouse." ”,

The shopkeeper took the order and left, in his opinion it was a big business, and he could make a good profit.

Shui yu, Jin Yu later understood, for the people of the Tang Dynasty, that is the diamond of later generations, very scarce and eye-catching. But the shopkeeper's lift is a basket! And it's all transparent! Jin Yu is very greedy for the Cheng family, and this basket is enough for a middle-class person to spend for a lifetime.

"Big brother, please choose." Cheng Huaimo waved his hand and asked the two strong men carrying the "glass slag" to wait outside the mén, and said to Jin Yu.

Jin Yu picked up a piece of water yu casually, and it was good, but it was smaller. It is best to have a piece of water in the lens of a pair of glasses, so that the difference between the two lenses is the same, which makes people feel more comfortable to wear.

Jin Yu picked out a piece of water the size of a cigarette box and said, "Just this piece, make two pieces of the same style." ”

Wearing glasses is a technical job, Jin Yu estimated Qin Huaiyu's eye power, two two hundred and five. The second step in fitting glasses was to measure Qin Huaiyu's interpupillary distance so that he could cut the glasses, so Jin Yu instructed Jia Laohan to make two round lenses of the same size.

"Done." Jia Laohan took the water with both hands, observed it, and said, "It can be completed in three days." ”

"No problem! If you do it well, there is still work for you to do. Jin Yu said with a smile. As long as people are sure that they can do it, Jin Yu is very happy, saying that he gave the scope on the bow and crossbow to Cheng Yanjin, it is inconvenient to hunt, and Jin Yu has not practiced to the level of a hundred steps through Yang.

"Shopkeeper, how much?" The jiāo generation is also the jiāo generation, and it is time to pay for it below. For Qin Huaiyu's glasses, Jin Yu deliberately "robbed" a few gold luo from Yang Ying, and the three taels were converted into the currency of later generations, about 50,000 yuan.

"Childe, please go to the tea room and sit down for a while, and put this water into the storehouse." The shopkeeper's arch hand avoided Jinyu's inquiry.

Jin Yu knows, it seems that the professional quality of the people is very high! I don't think this is the place to talk about price. Now that everyone has spoken, Jin Yu put away his manuscript paper and walked towards the tea room, and Cheng Huaimo followed silently behind.

"Big brother, what the hell is this thing for?" When he arrived at the tea room, Cheng Huaimo finished pouring tea for Jin Yu, and finally An Nai couldn't help his curiosity and asked.

"Correcting eyesight." Jin Yu's hands were a little cold, and the tea bowl was too small to hold, so he simply held the teapot in his hand, the size was just right, take advantage of it! "Some people can't see things in the distance clearly, and some elderly people can't see things near clearly, you can use this thing to correct it. As long as you put it on, you can see things in the distance and in front of you. ”

"Oh? So amazing? Cheng Huaimo was interested, and there were words in his mouth, pinching his fingers and gesturing, looking like a magic stick. He didn't doubt what Jin Yu said.

Looking at Cheng Huaimo's appearance, Jin Yu knew that this kid was pondering the value in it again, and he was also not worried that Cheng Huaimo would be tinkering with glasses behind his back. First, he doesn't know much about the degree, and second, if the name of this stealing master spreads, it will be a fatal blow to the Treasure Pavilion.

The shopkeeper of the Treasure Pavilion was worried about this big patron in his heart, and after putting Shui Yu down, he hurried over.

Jin Yu still warmed his hands with a teapot, watched the shopkeeper come in, and asked again: "How much?" Can you say that now? ”

"Thank you for your patronage, a total of three hundred and sixty yuan, and I will collect your sixty yuan deposit first." The treasurer replied with a smile, he was waiting for Jin Yu to ask the price now, so as soon as Jin Yu asked, he opened his mouth and answered.

"How much?" Although Yang Ying once told him that the jewelry was 100 yuan yuan, Jin Yu didn't care, and thought that the women didn't understand the market, but they didn't know that it was indeed this price!

"Three hundred and sixty taels, if the prince pays in cash, that is, four hundred and fifty taels of silver, that is, seventy-five taels of gold. The deposit is sixty taels, that is, seventy-five taels of silver, and twelve taels of gold. "The shopkeeper has been playing with money all day long, and the exchange rate here is very clear.

Jin Yu was speechless, he thought the money he got today was a huge amount of money, but he didn't expect that even the deposit was not enough! The price of a pair of glasses is 230,000 yuan! This price can go down in history, right?

Black! It's so dark! It's really TM black! Jin Yu was hesitating to explore the production of glass by himself, and the price of 230,000 should be enough to explore 100 formulas. Jin Yu feels that he is a poor man, and a large family can only have seven or eight hundred yuan a month, fortunately, his family is not short-sighted, otherwise a pair of glasses will die of old age, if it is accidentally broken, wouldn't it be even more sad? A year's pocket money is gone! ,

"What money to talk about? Talking about money hurts feelings! Before Jin Yu could speak, Cheng Huaimo came back to his senses and waved his hand to push the shopkeeper out.

The shopkeeper of the Treasure Pavilion stopped talking, and seeing Cheng Huaimo's glaring appearance, he had to go out reluctantly.

"Big brother" and "Big brother!" Cheng Huaimo shouted again, but Jin Yu didn't react, and shouted again in an accentuated tone.

"What?" Jin Yu reacted, shook his head and sighed: "Your lenses are not something that ordinary people can afford!" Call the shopkeeper in and check out! I've brought so much with me today, and I'll count the rest later. Jin Yu took out his purse and poured a few gold luozi on the table, as well as a few pitiful copper plates.

"Feelings, didn't you hear my little brother speak just now?" Cheng Huaimo was a little sad, and his performance was simply a làng Fei expression.

"What did you say?"

"The little brother said that he won't accept your money, it's a gift from the little brother!" Cheng Huaimo said generously.

Jin Yu looked at Cheng Huaimo suspiciously, and said, "What the hell do you have an idea?" Don't charge money? Don't charge money, what do you eat up and down this treasure pavilion? ”

"No one can make money from big brother, don't you say?" Cheng Huaimo laughed disgustingly, this time is different from the business of disinfectant wine, compared to the profit of glasses, the low profit of that thing is scary. As long as he wears six or seven pairs of glasses a month, Cheng Huaimo is confident that he will make a thousand net profits!

"What is, less in this set almost." Jin Yu seems to understand what Cheng Huai wants to do, no one's money can earn his own money, that is, he can earn other people's money? How can I make someone else's money? Let yourself contribute to the method of determining the degree!

"Hey, hey." Cheng Huaimo touched his head and told Jin Yu about his plan, "Big brother, look, the cost of these two lenses plus labor costs is only one hundred, if they are sold to those dignitaries with eye diseases, this business will be less than five hundred yuan, what a big profit!" As Cheng Huaimo spoke, little stars appeared in his eyes, as if he saw a glittering rare metal beckoning to him.

"There seems to be some truth to that!" Jin Yu nodded, who doesn't like money? 1,000 a month, up to all the businesses of my family now add up to make more money, very you!

"How? Do you want to do it? Cheng Huaimo just frankly gave his profit margin to Jin Yu, which was in the spirit of honest cooperation, and now he is straightforward again.

"! Why don't you make money if you have money? Jin Yu's eyes rolled, "I only show the data of the lens, I don't invest money, and I account for two percent of the shares!" ”

"Sancheng!" Cheng Huaimo gave Jin Yu another 10% stake before agreeing. In these years, you have to pay attention to the teacher to be famous, and Jin Yu himself can also assign someone to find out the thickness of the lenses, but the investment is too large, and the second is that the teacher is unknown. With Jin Yu's ability, maybe he can make up something in the future, this time it seems that he has suffered a small loss, but in fact, this deal is very cost-effective in the long run, Cheng Huaimo thought to himself.

Jin Yu's heart was also secretly cool, Cheng Huaimo didn't stop him when he started the brewing workshop, and he bought the wine at the market price, and when he figured out the firing method of the glass, he couldn't say anything to regret it, this deal is a good deal! This time, I just used high mathematics to calculate the focal length and thickness of the lens, and I got two percent of them in vain.
