The entire East Asia is paying attention to the situation in Japan, but Zhu Cixuan is already at the General Administration of Military Weapons of Jiangnan in Taiping Prefecture.

Not long ago, the Military Industry Research Institute developed a batch of epoch-making equipment, breech guns and field artillery.

After the division of civil and military rule, a military weapon department was set up under the military aircraft, and the Shenji Hou Zhao Jinglin was appointed as the Minister of State, indicating that the court attached great importance to it.

The Jiangnan Military Weapons General Administration, as the first comprehensive military factory in the Ming Dynasty and even the world, carefully selected nearly a thousand craftsmen from the local military weapons bureaus of the Ming Dynasty to serve in the bureau.

When Zhu Cixuan entered the artillery factory of the General Administration of Military Appliances accompanied by Zhao Jinglin, he saw encouraging slogans everywhere on the artillery factory. The heat inside was so hot, the iron slurry soared, and all the craftsmen were busy, and there was a scene of enthusiasm.

The head of this cannon factory is Earl Li Dongfeng, who has a very deep attainment in rockets and artillery. When Zhu Cixuan saw him, the fifty-seven-year-old Earl Li was wearing reading glasses and concentrating on the newly completed batch of artillery.

The older generation of scientific research workers are very serious, meticulous in building a country, and dedicated their youth to the dream of a strong country.

Even though Li Dongfeng was awarded the title, he was nearly 60 years old, he has never forgotten his original intention for so many years and has always worked in the front-line position of the artillery factory.

Li Dongfeng was concentrating on his mind, and Zhu Cixuan and others did not notice it when they came in. After Zhao Jinglin reminded him, he hurried over to greet him.

Seeing him saluting respectfully, Zhu Cixuan helped him up and said in a harmonious voice: "Shen Weibo, he is all noble, why are he still watching the inspection process in the artillery factory?"

Li Dongfeng held his glasses and replied: "Thank you for your concern. I was kind to you in this factory. I dare not forget my original intention and mission."

Zhu Cixuan held his hand and patted gently: "Don't forget your original aspiration and keep your mission in mind. Shen Weibo is my role model in the Ming Dynasty!"

He turned around and said to Yang Shicong, a senior secretary of the Hanlin Academy who came with him, "Yang Qing, go write an article, the title is "Learn from Count Li Dongfeng"!"

Yang Shicong, who had always wanted to show off, agreed happily, and just slapped his chest to ensure that this article would satisfy Emperor Zhu and achieve the purpose of publicity.

Next, Li Dongfeng led Zhu Ciyang and others to patrol the artillery factory back and forth, while introducing Zhu Ciyang the new product of the artillery factory - Wuhuang Cannon!

The only criterion for testing new products is test shots!

Everyone came to the wide site behind the artillery factory, which was specially used to test military products. When Zhu Cilang arrived, ten newly cast "Martial Emperor Cannons" had already been brought into place.

"Arson ready!"

The emperor visited him in person, and Li Dongfeng was in high spirits. He was so majestic that he passed a series of commands, allowing the artillerymen to aim at a series of targets in the distance.

Zhu Cilang looked carefully and was surprised to find that Li Dongfeng's so-called new cannon was much smaller than the Red Cannon. The entire cannon body was only about 1.67 meters long and the caliber was not large.

According to Li Dongfeng's introduction, these new guns weigh only one thousand kilograms. The gun body, gun frame and wheels weigh 2,200 kilograms. The full gun, plus the front trailer and the attached ammunition box, weighs 3,500 kilograms.

Compared with the previous use of the Red and Wild heavy artillery weighing 7,000 or 8,000 kilograms of the Ming Dynasty, the maneuverability is very strong. What is important is that the range of the new gun is no worse than that of the Red and Wild artillery, and the shooting accuracy is far higher than that of the Red and Wild artillery.

What made Zhu Cilang depressed was that he looked very familiar when he saw these cannons, and countless films and pictures from later generations appeared in his mind.

After thinking about it carefully for a long time, he suddenly had an idea: Isn’t this the fuck just a Napoleon cannon?

Amid Li Dongfeng's call, these cannons lined up, the black muzzles were constantly adjusted, and each cannon was also equipped with a pair of shiny cannon mirrors.

These gun glasses are made of glass. The earliest glass maker in the world was the ancient Egyptians. Commercial glass appeared in the 12th century. It was not a rare thing in the Ming Dynasty. There was a glass factory specializing in glass manufacturing in the capital, which was one of the factories in the 24th Supervisory Bureau.

Before this, due to limited craftsmanship, bubbles could not be avoided in colorless glass, and most of the Ming Jun's telescopes and gunshots were made of crystals.

There are many colorless crystals produced in the East China Sea (Northern Jiangsu) in Zhili, which farmers can pick them up in the fields, and are even more common toys in the Shilin class in Jiangnan.

The raw materials for producing gunshot lenses are not a problem, they mainly lie in the design and grinding of lenses, and have high requirements for process and optical knowledge.

However, the Ming Dynasty was full of talents, and Princess Kunxing's son-in-law Sun Yunqiu was the most awesome optical expert in the Ming Dynasty. The princess's mansion also opened a chain glasses shop, covering all parts of the Ming Dynasty.

Under Sun Yunqiu's research, the technology of colorless glass was not only conquered, but also invented the process of making large pieces of glass. Since then, glass has become an ordinary item in the Ming Dynasty.

In military industry, in order to meet the needs of making military telescopes, Sun even made optical glass.

At this time, Zhu Cixuan was holding a royal telescope made by Sun Yunqiu to watch the new gun shooting target.

The whole body of this royal telescope is made of a yellow metal surface, which is exquisitely made and can lengthen and shorten the observation distance.

The civil and military ministers accompanying him also watched with telescopes, waiting for the test of the gun data.

The artillery soldiers who tested the artillery were well-trained, and the observers kept reporting data, and each gunner adjusted the muzzle when aiming.

The artillery in the Ming army now cannot be used to become artillery after joining the army by practicing cannons for a few launches. Each artillery needs to master a lot of mathematical knowledge, such as geometric foundations, plane triangles, and spherical triangles.

In addition to geometry, you also need to know how to solve single equations, multiple equations, quadratic equations and preliminary applications in geometry (especially triangles).

Nowadays, in the state-owned military academies of the Ming Dynasty, there are artillery majors. Mathematics is the foundation, as well as mechanics in physics. Navy artillery also needs to learn navigation, positioning and other navigation knowledge.

Because of the fireworks these days, there is a fatal problem: you can’t see the bounce point.

Therefore, artillery soldiers must learn to calculate the angle and orientation of shooting, know how to measure range, calculate ballistics, etc.

Only when the artillery is calculated accurately can it fight quickly. Only when the artillery is calculated quickly can it fight quickly. It is invincible wherever it points on the battlefield!

As for what they learned, the Ming Dynasty had begun to popularize Western mathematics and Arabic numerals, and artillery was the first type of person to be taught.

It has to be admitted that Western mathematics is currently slightly ahead of the Ming Dynasty, especially in the use of symbols and Arabic numerals, which is simpler and more convenient than the use of Chinese characters and numbers in Ming Dynasty mathematics.

Arabic numerals were invented by Indians and were only called Arabic numerals when they were passed on to Europe by Arabs.

As early as the eighth century, Arabic numerals were introduced to China as Buddhism spread eastward, but they were not accepted by the Chinese writing system at that time.

In the 13th century, it was brought into China by the *** religion, but it was not successful. In the 16th century, when the East and West cultural exchanges, scholars such as Xu Guangqi of the Ming Dynasty began to translate a large number of Western mathematical works. They also translated the Arabic numerals in the book into Chinese characters, making it difficult for Chinese mathematics to learn.

It was not until Zhu Ciyang became emperor that he formally established mathematics in education, allowing students to formally learn Arabic numerals and Western mathematical formulas.

Last year, Louis XIV wrote a letter to Zhu Cixuan, which also mentioned that he wanted to send French mathematicians to the Ming Dynasty for communication. Afterwards, Zhu Cixuan agreed and replied to Louis XIV and asked for several people.

For example, French mathematician De Zag, one of the founders of projective geometry, was a military engineer and architect, and had contact with mathematicians Mason, Descartes and others. (Descartes died for several years)

There is also French mathematician Ferma who contributed to calculus, and Pascal, who was once known as the "intermediate link between Archimedes and Newton". (named by the pressure unit)

These three are famous mathematicians in the 17th century, and they are all in France. They are a bit of the kind that has not yet died, and can be used when they come.

Unlike Newton, who is just eleven or twelve years old now, he is a kind of shit in school, and it is useless to come to the Ming Dynasty. At most, he can make some gadgets for the crown prince Zhu Hebi.
