Subsequently, Wang Bin took all the screw rods he made into the science and technology mall, and he himself immediately entered the science and technology mall store.

    When he came to the shop, Wang Bin first put all the screw rods in his hands in the container. Of course, when putting these glass screw rods, Wang Bin opened them according to the precision level of these screw rods.

    After placing the glass screw rod, Wang Bin returned to reality, used some glass in his own laboratory, then processed some numbers with CNC machine tools, sprayed colors, and entered the store of the science and technology mall again.

    He is going to use these glass figures to price these glass screws.

    For grade 4 precision screw rods, Wang Bin is not going to change the price, but will sell them according to the price he negotiated with Xu Zhenming.

    Those above level 3 cannot be sold at this price, especially those reaching level 2 accuracy.

    After all, whether it is level 2 or level 3, the processing time of each screw rod also needs at least five minutes, especially for Level 2, it takes at least ten minutes. Therefore, if the previous 25 energy coins are one ton, he will definitely lose out.

    Therefore, Wang Bin decided not to calculate the price per ton before, but according to the price of each screw rod for screw rods with accuracy above level 3.

    The third level Wang Bin decided to temporarily set the price of 100 screw rods per energy coin, while the second level was set at the price of 10 screw rods per energy coin.

    As for if they can produce complete ball screw in the future, the price is being set.

    Although the price seems to be a little high in Wang Bin''s opinion, even for the three-level precision screw rod, the price of each is equivalent to 10000 yuan, and the second level is equivalent to 100000 yuan. However, think about it, it''s in the mall! It can''t be calculated according to reality.

    Take the region where Wang Bin is now, that is, the region in the later stage of class zero civilization. According to the systematic division, it starts from the era of industrial revolution until the civilization goes out of its home star.

    After all, it is impossible to go out of the home planet for hundreds of years from the industrial revolution.

    Take the real human civilization for example. It has taken hundreds of years since the industrial revolution, but the level of civilization has only increased by a mere 0.25 level.

    Although according to the current development trend of human civilization, it may be possible to get out of the mother planet in a hundred years, this is only the human civilization in Wang Bin''s world.

    In the Post-Zero civilization of the science and technology mall, in addition to human civilization, there are actually many civilizations. Among these civilizations, in addition to the development potential of a few civilizations, the development speed is faster than that of human civilization, there are many civilizations. Their intelligence, civilization development speed and civilization development potential are far inferior to that of human beings.

    Therefore, these civilizations may take hundreds of thousands of years, and they may not be able to develop from the level equivalent to the level of the industrial revolution to go out of the home planet.

    Moreover, the development of civilization is not smooth sailing in every world, especially in the late stage of class zero civilization.

    According to the previous systematic introduction, more than 90% of the countless civilizations in the universe were destroyed in this era.

    Of course, there are many reasons for the collapse, but generally speaking, there are only four words, natural and man-made disasters.

    Natural disasters, nothing to say, are all kinds of natural disasters or the invasion of higher civilization. After all, not all universes have the protection law of lower civilization.

    However, the proportion of civilizations destroyed by the invasion of higher civilizations is actually very low, less than 1%, not even as many as those destroyed by supernova explosions.

    Because according to the systematic introduction, in countless universes, most of the higher civilizations of the universe have a common agreement, that is, any Aerospace civilization can not make any form of contact with the civilization that has not gone out of its parent star, let alone invade the other''s parent Galaxy "planetary system".

    Even if other forms of natural disasters are added, such as the crustal change of the parent star, the impact of asteroids, the solar wind emitted by stars, the total number of civilizations destroyed will not exceed 30%.

    In other words, 70% of the reasons for the collapse of civilization in this period were caused by the civilization itself.

    Therefore, even in the later stage of class zero civilization, the higher the civilization level, the less the number. Take the area where Wang Bin''s shop is located. The number of civilizations that exceed the current human civilization in the world where Wang Bin is located is gradually only 3% of the total number of civilizations in this area.

    The price set by Wang Bin is not too much.

    At the same time, Wang Bin also wants to wait until tomorrow to process more mechanical parts with the machine tool in his laboratory and put them in the shop. I''m sure many people will be interested!

    Soon, Wang Bin marked the prices of these screw rods and was ready to inform Xu Zhenming.

    However, before Wang Bin had time to act, he found that a person came into the door of his shop, and this person Wang Bin was also very familiar with. It was Donald William who had been to his shop several times and bought a ton of glass from him.

    "Welcome, Mr. William! I wonder if you are satisfied with the glass of Tiangong technology. What else do you need this time?" Wang Bin said to William with a smile.

    "Hello, shopkeeper! I''m very satisfied with this glass of your Tiangong technology, so I want to order some flat special glass from you. I don''t know if you have Tiangong technology, shopkeeper?" Donald said.

    "How much Mr. William wants. If the quantity is large, we Tiangong technology does not have it, because we can''t produce this glass on a large scale. It will take some time. Of course, if you don''t need a large quantity, we Tiangong technology can sell you some!" Wang Bin said.

    "Good! Mr. shopkeeper, I don''t need a lot of quantity this time. Of course, it''s much more than the quantity I bought last time.

    I want 50 tons of glass this time. I don''t know the shopkeeper. Do you have Tiangong technology? "Weili said.

    "Fifty tons? No problem, but we need a month to produce. I wonder if you can accept it, Mr. Donald," said Wang Bin.

    Hearing Wang Bin''s words, Donald thought for a moment and said, "shopkeeper, can''t you hurry up! After all, the world I live in is not peaceful now, and the whole world is at war.

    This is especially true in my country. The need for all kinds of materials is endless. Even if I have bought a lot of materials from the mall, it is far from enough for this war. "

    After listening to Donald''s words, Wang Bin nodded and then said, "Mr. Donald, it''s not impossible to hurry up, but if so, it will have a great impact on the reality of Tiangong technology.

    But if you are willing to offer a higher price, Mr. Donald, it is not impossible. "
