    "That's good, just work hard." I nodded with satisfaction. At this moment, I could already see a building hidden at the foot of the mountain in the distance, and finally arrived.  "Your Majesty, look at these, these are the mirrors that left the factory this time. However, the yield rate is still not enough. It is close to 30% at most." Sun Zhongsheng, the head of the workshop, stood next to me, pointing to the various mirrors placed in front of him in the warehouse.  Said the fifty-dollar glass mirror.  "The other 70% have more or less defects of one kind or another." "There are so many defective products?" I couldn't help but sigh. However, compared to the previous 15%, but  The yield rate has doubled, which is already quite good "There is no way, the area of ????the glass is too large, and it cannot be squeezed hard, it is difficult to make the tin foil stick to the glass. In the end, it was an old craftsman's idea.  The method is to put a thick cloth under the glass, then put the dough on the tin foil, and roll it out with a rolling pin. After hearing this, I couldn't help but nodded.  Indeed, it seems that I am too impatient. The reason why I want to get such a big mirror is naturally to enjoy it myself first and decorate my bedroom with it, and then start selling it.  I can't let my bedroom be made of thousands of small mirrors, right?  I knew that day when it would be completed, so I asked these people to make the mirror bigger.  It seems that it is indeed very difficult to eat a big fat man, but I really didn¡¯t expect that those old craftsmen could actually think of such a crude way to do it.  "Pass on my master's order, the old craftsman who came up with this method will be rewarded with five hundred coins. If there is someone who can improve the yield next time, as long as it proves that the method is effective, I will not be stingy with the reward."  The old craftsman who came up with the idea came to express his gratitude with excitement. After comforting the old craftsman, I was actually very satisfied in my heart.  I remember the history of glass mirrors I saw in later generations. The price of a small, palm-sized glass mirror can reach 150,000 francs.  That is, at least today, it is equivalent to 30,000 to 50,000 strings.  No matter what, if those defective products are thrown out, they will definitely be regarded as family heirlooms, worth tens of thousands of gold.  I asked someone to bring a glass mirror and put it in front of me to look at it carefully. Indeed, the yield of this ancient mirror-making method is indeed much lower than that of later generations of industrial production, but it can produce such a clear mirror.  This is already an incredible achievement.  I also asked those workers whether they strictly followed the operating procedures and whether they strictly followed my requirements when entering the production workshop and put on masks filled with fine carbon and windproof glasses.  "Your Majesty, please rest assured. These people are all old people in the house. Who dares not to listen to your words? Besides, you are also thinking about their safety." The person in charge of the workshop replied seriously.  "Well, that's good. By the way, these glass mirrors will be sent to the villa early tomorrow morning. Install them quickly. I only have one bedroom. I don't want to have to sleep in other rooms in the middle of the night, you know?  ? ¡°Don¡¯t worry, you can put all fifty glass mirrors together in an hour at most.  "The person in charge of the workshop said with confidence. "That's the best.  Also, show me where the defective products are placed.  "I nodded with satisfaction. If my bedroom were covered with these mirrors, it would be equivalent to millions of dollars in money and silk. Tsk, tsk, tsk, I'm afraid the Palace of Mirrors in Versailles is not as good as my master's bedroom.  After a short while, I came to another warehouse, where there were many glass mirrors, but each mirror had more or less flaws of one kind or another. Even though some mirrors did not have major flaws, they were.  The face is somewhat distorted by the photo, which is naturally impossible to do. "Of these thirty pieces, you will carefully select each piece for me, pick out the available parts, and then cut it.  Use gold for edging" Although these mirrors have many flaws, there are also many places that can be used. "Yellow, gold for inlaying?  "The person in charge of the workshop stared wide-eyed, and he couldn't help but say, "Nonsense, just use gold if you are told to inlay it with gold.  As for you, depending on the situation, circles, squares, rectangles, and even polygons can be formed, but they must not exceed the size of a palm, do you understand?  "I put the glass mirror with at least four or five wrinkles back to its original state. Just from this piece of mirror, I can cut at least ten pieces of palm-sized mirrors. After they are inlaid with gold, I won't be able to sell them.  300,000 to 50,000 guan, wouldn¡¯t it be an apology for my master¡¯s ingenuity? After reading this, I walked to the workshop on the other side. Here, extremely pure glass is being polished. Most of these polished glass products are  All will be used to make telescopes, and only a small amount will be used to make microscopes. After all, the use in military applications is much greater, and microscopes currently only play a role in medicine.For example, the old man Sun Simiao hardly leaves home once a month now. He is often studying the various medical devices given to him by this young master, and also explains the usage methods and specifications of each medical device.  Everything was written down and compiled into a book.  It can be seen that Sun Simiao is really dedicated to his work, at least I can't have his passion for loving one line of work to death.  Not only these two, but also beakers and glass tubes. In short, all kinds of cups and tubes needed for chemistry are available here. Many large bottles are even made. This is naturally to supply the sulfuric acid plant.  in use.  Today, the production of sulfuric acid is much higher than at the beginning.  However, its current main function is still to conduct testing in the laboratory. At present, 80% of the laboratory personnel are Taoist priests, and the other 20% are specially selected for their loyalty.  Students with strong interest in science and technology.  At present, the plate armor treated with sulfuric acid passivation has been tested for a year. So far, no traces or rust spots have been found, while ordinary plate armor has been tested in less than half a year.  It has already appeared on the rust spots. This achievement makes me and all the staff of the sulfuric acid research laboratory very happy. After all, if such passivation can be used on a large scale, then in the future, light  I don¡¯t know how much money I can save on plate armor maintenance and replacement of rusty plate armor.  At present, those researchers are investing in new research with greater fighting spirit and enthusiasm. Sulfuric acid has extremely wide uses, and with my advice, I believe they will be able to develop it in the near future.  Nitric acid, by that time, nitroglycerin, ammonium nitrate and many other practical products will appear in people's eyes and lives.  In my opinion, the preparation of nitric acid is simpler than that of sulfuric acid. You only need to use the laboratory preparation method, and use sulfuric acid and sodium nitrate to heat together to generate nitric acid and sodium bisulfate.  Didn't nitric acid come out?  As for sodium bisulfate, I really don¡¯t know what this thing is best used to make, but they have to experiment with these things themselves.  As for making breech-loading guns, it is no longer a dream, because with nitric acid, not only can you make smokeless gunpowder, but you can also make primers for breech-loading guns.  After inspecting my own research institute, I naturally have to inspect the country¡¯s weapons and equipment manufacturing plants and weapons research institutes for the sake of the country and the people.  Swords and other gadgets are also produced here, but it is only as an experimental production. The researchers here are not doing it to make money, but are trying to research how to make the weapons sharper and more flexible at the same time.  and endurance.  In addition, we are also specializing in the production of artillery and muskets, but it is currently in experimental production.  Right here, I saw the hydraulic artillery retraction device, which has been successfully produced.  After this anti-recoil device is used on the artillery, the gun mount is connected to the gun body through it, and the gun mount becomes an elastic gun mount.  When firing, the gun body recoils relative to the gun frame, and the entire gun does not move backward.  The anti-recoil device consumes most of the recoil energy and greatly reduces the stress on the gun mount, thus greatly reducing the mass of the entire gun and increasing the firing speed.  In this way, the breech-loading cannon can also be made lighter.  After asking those researchers, I learned that currently, five types of hydraulic retracting machines of different sizes have been produced. Depending on the size of the artillery body, it should be able to meet the requirements from 60 mm to 120 mm.  mm caliber artillery barrel.  The sixty-millimeter caliber is equivalent to the six-pound cannon of the later Age of Discovery, while the 120-millimeter caliber can fire thirty-five pounds of ammunition.  In the Western Age of Discovery, the caliber of a twelve-pounder gun reached 120 millimeters. Why?  Naturally, because of the different bullet shapes, the conical shells I want to use are naturally not the iron projectiles of that era. Of course, this is just a theoretical data. After all, the design of today's artillery barrels is still being improved. It is currently being used.  Most of the cannon bodies produced in experiments are made of cast iron and bronze. This does not mean that it is done as soon as it is cast. Instead, it requires multiple studies to determine what caliber of cannon body has the most suitable lethality and weight of the cannon body, and what kind of gun body is best.  Doubling the diameter can obtain a good range, and what other methods can be used to make the inner wall of the artillery barrel smoother, heat-resistant and corrosion-resistant.  What method can be used to make a gun barrel of the same thickness stronger and more durable.  In short, all kinds of extremely difficult experiments are all in preparation for making better artillery.  I don't want to make any more so-called firearms that can't even defeat the nomadic cavalry. That can only be regarded as the bud of the firearms age.  What I want to do is to ensure that the farming civilization of the Chinese Empire can eliminate the threat of nomadic civilization to the Chinese Empire in the shortest possible time.  ??In one sentence: Science and technology can not only strengthen the country, but also save it.
