The blackboard and chalk have been created by Zhu Youxiao, but in this era when everyone was still accustomed to brushes, it has not been promoted, but it has become commonplace in the Ordnance Department, the Royal Academy of Engineering and the Royal Academy of Sciences.

In the conference hall of the Royal Academy of Sciences, on the wall in the center is a blackboard painted by a bricklayer according to Zhu Youxiao's suggestion.

Zhu Youxiao at this time took chalk made with calcium carbonate and gypsum as the main ingredients and wrote the words "riffle" and "machine tool" on the blackboard, and explained it to them in a way that these scientific workers in the Ming Dynasty could understand based on their recent self-study understanding.

On the long table in front of him was a physical comparison for his explanation, the Miner rifle purchased through the system and a boring machine that can be processed accurately.

Zhu Youxiao did not tell them the origin of these products that violated the times. The ministers who were used to His Majesty the Emperor always took out some surprising things and did not ask much. They just listened to His Majesty's explanation patiently.

From what a clamp gun is to what a flintlock gun is, to the rifled gun named Minie by His Majesty, through Zhu Youxiao's lectures and various materials, these scientific workers in the Ming Dynasty have gradually mastered new knowledge. Some Bi Maokang and others have even learned to read simplified Chinese characters to study by themselves, rather than waiting to get the information translated by His Majesty Zhu Youxiao.

Because it was explained by His Majesty himself, this has become the highest-level classroom of the Royal Academy of Sciences. Those who can sit in the lobby are almost the leaders in the field of natural sciences in the Ming Dynasty and some mature old craftsmen who already have a basic cultural knowledge base.

According to the current official statement, only those who have obtained the title of Hanlin Academy of the Royal Academy of Sciences or the General Technical Office of the Royal Academy of Engineering, or those who are the chief technical director of the Ordnance Department, can hear His Majesty's lesson and become a disciple of the Emperor.

The Royal Academy of Sciences, the Royal Academy of Engineering and the Ordnance Department have now established a complete technical talent training system.

First, the Ministry of Works and the Inner Palace Supervision will have special institutions to recruit craftsmen from all over the country to Beijing, or directly wave to apprentices from the public, and then literacy will be carried out after recruiting.

The literacy teachers are naturally the children or old students invited from all over the country.

Although these people are not necessarily knowledgeable, they can't teach these people to recognize a few words. Moreover, in order to speed up the literacy process of these technical reserve talents, Zhu Youxue ordered the officials in charge of this matter to determine the salary of these old children or old students based on how many people they teach within one month.

In addition, Zhu Youxiao also asked officials from the Hanlin Academy to compile a dictionary called "Apocalypse Dictionary" with commonly used characters.

This dictionary has about a thousand words, and the criterion for success in literacy is whether you can recognize all the words in the "Apocalypse Dictionary".

After recognizing the characters, craftsmen will be assigned to the various departments of the Ordnance Division or the various laboratories of the Royal Academy of Engineering to perform assistant work, led by the old craftsmen.

Apprentices sometimes need to send specialized craftsmen to teach skills.

Since His Majesty has abolished the craftsmanship system and clearly stipulated that the court must obey the regulations of the court to teach family skills to apprentices designated by the court, and no private hiding is allowed, some old craftsmen have to teach them all, and of course the court will also provide subsidies.

Once an apprentice or craftsman can complete a certain skill independently, he can enter the Royal Academy of Sciences to further his studies and choose to listen to lectures from big bosses such as Xu Guangqi, Song Yingxing, or the emperor and his majesty Zhu Youzhai.

Those who graduate and master core skills will become academicians.

After becoming an academician, you can directly submit a memorial to the Emperor Zhu Youxiao to apply for grants to the research and development of a certain type of new thing.

Of course, when the memorial is submitted, you have to copy it to Xu Guangqi.

Once His Majesty agrees with Xu Guangqi's signature, any academician can receive a project fund ranging from 1,000 to 10,000 taels or even up to 100,000 taels from the Ministry of Works.

Once an academician of the Royal Academy of Sciences or the Royal Academy of Engineering applies for generous projects, he will take the lead in organizing various craftsmen to complete the research and development of the project.

Moreover, generally speaking, the amount of money is much more than the actual research and development money. Therefore, many academicians want to apply for the project money. After all, this will not only receive generous rewards or even promotions, but also make a fortune.

But not everyone can come up with a good idea casually.

What's more, some ancient people who had never taken these so-called technological innovations seriously before and had completely accumulated experience to improve the process.

Therefore, Zhu Youjiao’s classroom content has become the biggest source of inspiration for technological innovation.

This is also the reason why many people want to listen to Your Majesty’s lectures, because every time Your Majesty throws out a new thing, it means a new opportunity to make a fortune.

If you understand or remember, and do experiments after going back or feel that you can realize what His Majesty said, you can write a memorial to apply.

After the officials of the Ministry of Works and the Royal Academy of Sciences or the Royal Academy of Engineering have calculated how much your project will cost, they will send you a notice and distribute half of your funds in advance.

Chen Laitou, an old craftsman who used to be a glass craftsman, is now taking on such a problem, which is to create the big mirror that His Majesty placed in the Royal Academy of Engineering.

Because it is a topic that both His Majesty the Emperor and Mr. Song of the Royal Academy of Engineering attach great importance to, the application process of the old craftsman is also very easy. It was approved in less than four or five days, and he was also allocated a lot of silver.

Of course, Chen Laitou also made a lot of preparations before applying. As an old glass craftsman who has been working in the palace for decades, he now knows that the glass and the glass displayed by His Majesty are composed of silica as the main components, but the glass is mixed with impurities such as iron, which is not as transparent as glass.

The film plated behind the mirror is also silver, but the silver on the back of the mirror cannot be depressed and the color is different.

Chen Laitou once thought about making the silver foil thin and then sticking it behind the glass. For this reason, he even bought a piece of glass from Westerners at a high price, but he was very disappointed.

Mr. Chen was not discouraged. He first found something called quartz sand and pure caustic soda by His Majesty to make green glass according to the information given by His Majesty.

Then, he and a few craftsmen from his research team went to the manganese mine near Gyeonggi to find manganese dioxide, and then conducted a month-long experiment, and finally made out the transparent glass.

But this was only half done. In order to coat the silver film behind the glass, Chen Laitou forced himself into the library of the Royal Academy of Engineering for nearly half a month.

He used to be respectful and distant, and now he has become an old scholar. He is either silver or iron, and those who don’t know what he thinks he has traveled through time.

After Zhu Youxiao found out, he even summoned Chen Laitou and his team in person. Zhu Youxiao also personally guided them how to use silver nitrate and ammonia water to make silver ammonia solution, and use glucose water to reduce ammonia water to make silver mirrors.
