After Wang Bin finished, he found that there was no reaction in his shop and there was no change at all, but the pedestrians on the road became different.

    In the past, although many people were walking around on the street, no one looked at his shop, let alone someone entered his shop. Now it is different. Some of these pedestrians on the street will look at his shop.

    It can be seen from this that there must be some changes outside his shop at this time.

    However, when Wang Bin thought about these, he finally saw a man staying outside his shop and looked at his shop. After staying for a while, the man hesitated and walked in towards his shop.

    "Hello! Welcome! Tiangong technology." when the man walked into the shop, Wang Bin said politely and looked at the man.

    The man who entered his shop was a young man in his twenties and sixties, wearing clothes about the same as those in the 1980s and 1990s of Wang Bin''s world, with a pen pinned to his chest and a mechanical watch in his hand. Wang Bin can clearly judge the scientific and technological level of his world from this young man, It will never exceed the level of 2000 in Wang Bin''s world.

    "Hello! May I ask the shopkeeper, does the high temperature resistance of this glass sold in your shop really reach the 2100 degree data displayed on the sign at your door?" the young man looked at the shop carefully after entering. Then he smiled and said to Wang Bin.

    "What''s your name, sir?"

    "My last name is Xu! The shopkeeper can call me Xu Zhenming!" Xu Zhenming replied.

    "Hello, Mr. Xu! The data of the glass sold by Tiangong technology is absolutely true. Moreover, there can be no fake goods in the technology mall. I think you know this better than me!" Wang Bin said.

    At the same time, Wang Bin at this time also knows what world Xu Zhenming is in. He should be a parallel world in a novel. Its world development and scientific and technological level are very similar to Wang Bin''s world, but the era of this parallel world is not the same as Wang Bin''s world. He has come to the 21st world. It''s the 1990s.

    According to Wang Bin''s memory, this novel should tell the story of how the protagonist starts from a processing workshop and creates an intelligent empire.

    The young man in front of him is Xu Zhenming, the protagonist of the book.

    Xu Zhenming nodded, then looked down at the glass on the ground, knocked on some glass from time to time, and made a sound of admiration.

    "Shopkeeper, I have another question to ask. Is there any other product in your shop besides this glass?

    Although this glass is very advanced for the world where I live, it is definitely something we can develop now, even with manufacturing technology.

    But according to your clothes and the product in your hand, I can judge that your world is definitely a world with very advanced science and technology, at least several decades more advanced than my world.

    So I prefer to get other products or technologies than glass, "said Xu Zhenming.

    "Hello! As you said, according to my personal judgment, the science and technology in my world should be at least 30 years ahead of your world. However, it is a pity that Tiangong technology has just opened, and we can''t sell other products except basic materials. At the same time, we can''t sell other products except our own products, and we are now Only special glass can be produced in China, so there are no other products for sale, "Wang Bin replied.

    Obviously, Wang Bin''s answer disappointed him, but he smiled and said to Wang Bin; "Well, since the owner of your shop has just opened, he can only buy other products from you when your shop reaches a higher level. As for your glass!" when he said this, he stopped, thought about it, and said to Wang Bin: "I wonder if you can introduce the specific data of each performance of your glass carefully. After all, your store only shows the high temperature resistance of this glass, not other performance."

    "Yes!..." then Wang Bin told the young man the specific properties of this glass. In the process of introduction, Wang Bin would exclaim every time he introduced a data of this glass.

    "Mr. shopkeeper, it is obvious that the glass of Tiangong technology is indeed very advanced, and can also be used in many products and equipment. Even for me, it is very useful, but in terms of price, the price of 15 energy coins per ton is really a little high." Xu Zhenming thought and said.

    "Mr. Xu, the performance of this product of Tiangong technology is absolutely worthy of this price, because this price is calculated from the actual sales price of Tiangong technology, that is to say, in fact, this price is consistent with the actual sales price of Tiangong technology.

    What''s more, the price is actually the average price of this product. If the glass model you buy is very complex, such as glass with irregular and complex shapes, the price will be higher, but if the glass you buy is only flat glass, the price will be lower. " Wang Bin explained.

    "Any shape is OK? If I want you to process this glass into a ball screw on the machine tool, and achieve a high precision level in terms of precision, can you do it and how about the price?" Xu Zhenming said.

    After listening to Xu Zhenming''s words, Wang Bin thought. It is obvious that for Xu Zhenming''s era, especially for Xu Zhenming''s country, the ball screw is indeed one of the important factors restricting the development of machine tools, especially the high-precision ball screw.

    But for the world where Wang Bin is now, it is different. After decades of development, many technologies in China have made full development. Many products that could not be manufactured have been solved now, and even some mechanical processing workshops with a little technology can be produced.

    The ball screw is no longer a problem for Huaxia now. Many factories can produce it. As for the accuracy, it is no longer a problem for the world where it is now. Even for P2 and P3 ball screw, many manufacturers in Huaxia can produce it, and even higher P1 precision can not be produced.

    However, Xu Zhenming is really whimsical about using special glass to process into ball screw. After all, the material of glass and the material used by ball screw are definitely two different things, compared with the material used by ball screw.

    The material of their glass, its processing difficulty, can definitely make people crazy, but he didn''t want to give up his first customer in the technology mall, so he replied; "Making special glass into screw rod, Mr. Xu, you are kidding! Even if you want to process ordinary glass into ball screw rod, it is even more difficult, not to mention using our special glass.

    However, if Mr. Xu must try, I can try, but I said first that even in the world, it is much more advanced than Mr. Xu''s, but it may not be able to be processed, especially when the accuracy is guaranteed.

    However, Mr. Xu, you should be prepared. Even if you can make our glass into a ball screw, the price can not be calculated according to the price of 15 units of energy coins and one ton. It needs at least 20 energy coins or even higher. The specific situation depends on the manufacturing cost.

    So it may not be very cost-effective for you. After all, the price of our glass itself is far higher than the price of some ball screws with high precision. Please consider it clearly. "

    "Store manager, perhaps for your age, it is very simple to manufacture a ball screw in your country. Even if it is an ordinary machining plant, the precision of the ball screw manufactured is already very high.

    However, in the age of my world, it is even more difficult to manufacture a screw rod with the required precision. Even large state-owned machinery manufacturing companies may not be able to manufacture it.

    Of course, if money can be used to solve it, it will not be a problem, but unfortunately, in my age, even if I have money, I can''t have a lot of foreign products, including ball screw?

    That''s why I want to ask if your glass can be made into a ball screw. After all, your glass is better than ordinary steel in terms of material, and even the material used for the ball screw can''t be compared in terms of thermal expansion and cold contraction coefficient.

    That''s why I''m whimsical. I want to use your glass to process into a ball screw to replace the high-precision ball screw that must be imported from abroad in my age, and even money can''t buy it!

    Of course, the premise is that the price does not exceed my expectations. If the price exceeds what I can afford, then I don''t say it, "Xu Zhenming said.

    "Mr. Xu! I wonder if you can afford the price of 25 energy coins. If you can, I can try this order.

    Because at present, Tiangong technology has no equipment for processing screw rods. If we receive your list, we must also buy corresponding equipment. Even in my age, if we want to buy high-precision machine tools, the price is not cheap, "Wang Bin said!

    "25 energy coins per ton? Yes! I''ll order one ton first. If I can, we will keep up with the follow-up orders, and we will have more orders for other parts besides the screw roller.

    And I won''t let you try Tiangong technology in vain. Whether it''s success or failure, I must thank you again in the future. "Xu Zhenming said with a serious expression.
