To get the support of the villagers, for a whole February, Deng Shifeng took students and a few skilled workers to start focusing on several major projects, which was also called the technical breakthrough month by later generations.

The first to get is the glass that has been pre-researched for a period of time, two students and workers some time ago, did not use those slag-like rough quartz sand to trial production glass, although it has a high temperature of melting silica, before and after also made such a pot of glass slurry, but due to the lack of purer raw materials, rich in various minerals of raw materials so that each trial of the glass is with a variety of different colors, plus the artificial failure of the additives put in the attempt to neutralize and remove the color...... Concentrated and thrown together, colorful, like a rainbow, is beautiful...... Moreover, there are many bubbles and impurities inside the glass, and it is an unsuccessful failure at a glance.

The continuous failure has affected the emotions of the students who followed Deng Shifeng to pre-study and prototype glass, which is a normal thing, after following Deng Shifeng, the students have seen too many miracles created by Daxian under the leadership of them, but now, the students have suffered failures and setbacks for the first time, and it is natural for them to be depressed.

But fortunately, Deng Shifeng not only understands the difficulty of producing glass, but also knows how to resolve these low feelings, and can find ways to make students understand that the road to science is not always easy.

Deng Shifeng first told the students about the difficulties of the scientific research process, and that it will not always be smooth sailing on the road of scientific research, especially many seemingly great inventions, in fact, after thousands of attempts to finally get the most perfect results. And the best example of this is the story of the electric light. The students now have a general understanding of what electricity is through their studies, and they also understand that electric lights rely on electricity to release heat and light energy (incandescent lamps) on the filament, especially the red-hot wire used in the car cigarette lighter to let them know more about this magical electricity. With the knowledge background, in the story, a certain immortal tried more than 2,000 times in order to find the most suitable and perfect filament, and finally found the most suitable material. Even if someone laughed at him for wasting time doing so many useless experiments, he replied sharply: "Failed two thousand times? No, no, no, I found two thousand materials that were not suitable!! (There must be a revision of the story to be told after the crossing)

After listening to Deng Shifeng's story, the students looked at the various failed results of each experimental attempt, and the various detailed recorded data related to them...... The students understood why the teacher kept the most detailed notes on his own, every time...... Isn't it just to find out the inappropriateness and mistakes again and again......

At the same time, Deng Shifeng also used a blowpipe to blow out all kinds of colorful and strange-shaped glass products in front of the students, including balls, ovals, bottles, and strange alien shapes that even he couldn't speak...... This playful blowing process was naturally a very fun experience for a group of children, and it didn't take long for more strange shapes and strange things to be blown out of the hands of the students; In the process of making the students happy to try production, it also allows the students to gradually master and summarize the skills of glass blowing in the experience......

It is precisely because of the many pre-research and trial production in front of the foundation, when Huang Zhangshi arrived from the outside of the relatively pure raw materials, for the technical research of glass production Deng Shifeng only appeared for half a day before moving to other projects, responsible for glass development and production of students, workers have basically been able to try to explore colorless glass on their own; Although it would be faster to have Deng Shifeng on site to guide them, Deng Shifeng felt that letting the students explore and try on their own would be more helpful for their growth. And even if it is those failed products, breaking them into glass powder is an important friction to make a rope fuse!!

Due to the good foundation laid in advance, the production of purer glass was only a matter of time, so Deng Shifeng focused his attention on metal processing. Now for the iron plant, the biggest problem is not to produce high-quality steel or even try to research the technology of alloy steel, the biggest headache of the iron plant is the technical difficulty of meticulous processing of these high-quality steel.

The hardness of steel is far from being comparable to wood, so processing metal is a very time-consuming and laborious work, in the past, according to the old grandson's approach, the simpler shape can be forged many times to make a general shape, and then use a simple file and grinding tools to slowly process and polish, the efficiency of this process is naturally not fast. And if the parts are more delicate and complex, the shape is changeable...... Not only is the skill level of the craftsman extremely demanding, but the man-hours spent are definitely not a small number......

What's more, the iron and steel embryos produced by the iron factory are even better in texture, and it is not too troublesome to make simple knives and long knives with low technical content, but if you want to produce firearms, there are various parts with changeable shapes and great precision requirements...... Just the original low-quality processing tools of Lao Sun Tou have already expressed that they can no longer be qualified for such a job. However, fortunately, Deng Shifeng still has a few sets of processing tools used by fitters, but it is impossible for each part to rely on these sets of tools to slowly see and file out...... Especially for the key parts of the main body like the barrel, this fitter table can't handle it!!

In Deng Shifeng's original plan, he was prepared to solve the high-hardness processing equipment such as hacksaw blades, files and metal new equipment and produce a batch of standard measuring tools, and then gradually improve the overall steel quality and processing level, and finally reach the metal machining level he needs. It's just that the current situation waits for no one, and it is impossible to develop step by step according to the plan, Deng Shifeng can only sacrifice those magic weapons in his cave in advance, and use the external situation to directly accelerate the improvement of the existing machining capacity.

If you want to start those plug-in magic weapons, installation and commissioning is not too difficult for Deng Shifeng, who has two old technicians in his brain, organizing people to level the simple road from the cave to the factory in Xincun, taking advantage of the night, driving a truck to slowly transport these most important treasures from the cave to the factory is not a difficult task, but to solve how to provide stable power has become a technical problem that must be dealt with.

Fortunately, on the handling of the vehicle, there are two 15 kilowatt industrial electric generators transported together, through the past few years, Guangxi due to the shortage of electricity, many small factories, shops and supermarkets have purchased the corresponding small generator set backup, this tens of thousands of dollars volume of less than half a cubic diesel generator set can basically ensure that several major equipment does not stop working. However, these things are very oily, and for Deng Shifeng, who now uses one liter of fuel to reduce one liter, he will never dare to consume it easily unless he has to. It's just that because of the change of plan, Deng Shifeng is only ready to split the two generators as a destroyer, separate the generator from the diesel engine, and re-transform the input power.

Originally, Deng Shifeng planned to use the water flow as a power to stabilize power generation after taking out the third sharp weapon -- cement, and using cement to build a small dam near the iron factory, and the construction of this small dam was not too difficult, in the whole Ming Dynasty, because Guangxi's economic and cultural development reached a new height, out of the use of Guangxi's rich water resources, this kind of water conservancy project that can both prevent floods and store water for irrigation has been generally built in Guangxi, and it is called Pitang Weir Dam according to the size of the water conservancy project. This kind of Pitang weir dam whether it is the official repair funded by the government or the private fund-raising of the private repair, reached a ** in the year of the Apocalypse, according to the record of "Xizong Record", from the first month of the fourth year of the Apocalypse to the end of December, Guilin and other nine prefectures and counties to build the Pitang polder, a total of 3,883 places; This figure was found in Guangxi's water conservancy construction in one year, which shows how rapid Guangxi's agriculture developed at that time. However, the dams that Deng Shifeng needed were higher, more stable and more complex than those of his time, after all, compared with those traditional dams that stored and channeled water, the dams he needed were not only higher, but also more functionally more complex.

But now that it is too late to wait for the dam to be built, Deng Shifeng has no choice but to turn his attention to the sky again - continue to use wind power to generate electricity!

Although several small wind towers have been built before, they are all small devices with a height of three meters and a radius of more than one meter of fan blades, and because they are only responsible for the power of multiple batteries and small bulbs for lighting, the main structure is less stressed, and there is no problem with using wood as the main structural material. But now to ensure the continuous and stable generation of high-power generators, then it is already a behemoth, plus huge fan blades...... Everyone unanimously turned the materials used to build the wind tower to steel......

After the preliminary design and detailed investigation of the different wind forces in the nearby mountains and passes, Deng Shifeng designed the wind tower with a height of 10 meters and a radius of 6 meters for the fan blades according to the wind speed, overall weight and force on the ground.

After the careful design of each part and the strict control of the production process, Deng Shifeng and Lao Sun Tou and Zhao Carpenter took their students and apprentices, not only from the production technology to study and tackle key problems, but also to control the size and error of each steel within a very small range, because if the error is too large, each piece of steel will cause assembly difficulties and even rework and remake delays in the overall installation completion due to errors when connecting.
