Emperor Chongzhen of the Ming Dynasty

Chapter 104
After Zhu Youjian said, he asked the imperial pharmacy to go to some imperial physicians to pick up Bi Maokang to Nanjing with Wei Guogong Xu Wenjue.

The reason is to let Wei Guogong Xu Wenjue pick it up.

Naturally, it is because these relatives of the Ming Dynasty have to do something for the country, and they cannot be raised for nothing.

Although these relatives are all founding fathers, or have made outstanding contributions to the Daming Jiangshan Sheji.

But most of these relatives are just dudes, and naturally they don't have much ability, but they are particular about life after all.

How to keep warm, how to treat diseases, and how to transport a patient from Huizhou to Nanjing safely may not be a big problem.

Xu Wenjue had just been imprisoned by Zhu Youjian for a period of time, how could he dare to have the airs of the first prince of the Ming Dynasty, so he naturally ran to Huizhou with his entourage.

It is said that Dongchang reported that the four famous doctors in Nanjing were all taken to Huizhou by Xu Wenjue.

Zhu Youjian is naturally quite satisfied with his obedience.

Although Zhu Youjian has a little knowledge of steel smelting, gun manufacturing and gunpowder ratio, the specific development and operation can only rely on practitioners of this era.

His experience with these experiments was not much better than that of these men.

Therefore, Zhu Youjian needed people like Song Yingxing and Bi Maokang very much.

Therefore, how long Bi Maokang can live, for Zhu Youjian, means how many more years Daming can improve.

Song Yingxing was taken by Zhu Youjian to the East Nuan Pavilion of Qianqing Palace.

This is Zhu Youjian's study.

From Arabic numerals to English letters to Chinese pinyin letters and the periodic law of elements, Zhu Youjian made them and pasted them on the wall.

There is also a wooden globe, a miniature version of the full map of Kunyu Wanguo, and wooden ironclad ship models, tank models and gun models made by Zhu Youjian himself.

Song Yingxing was naturally dumbfounded when he saw it. The Taoist said that since His Majesty came to Nanjing, he has specialized in strange skills like the previous emperor, especially carpentry. Now it seems that His Majesty is not what the censor said, it is really absurd government affairs, but Don't mean it.

Although Song Yingxing had never seen these models, he could guess that they were ships, chariots, and guns.

Zhu You gave Song Yingxing a seat by the inspector, and asked people to call the prince and Yongwang Dingwang together.

Although my own prince is not yet capable of governing, as a child of the royal family, it is necessary to learn some natural science, otherwise he will be fooled by a group of Confucian scholars.

For a while, Prince Zhu Cihong and Yongwang Dingwang also came to Dongnuan Pavilion.

After the successful move to the south, Zhu Youjian changed the names of his two younger princes to the vassal kings again.

After all, it no longer makes sense for them to be entrusted with Hangzhou and Nanchang.

Moreover, Zhu Youjian hadn't made up his mind about whether the vassal king should be kept in captivity like a pig in the fief, so he stayed in Nanjing for the time being on the grounds that the two princes were young.

"You are mainly in charge of steel smelting now, and it is impossible for me to explain these things to you one by one like teaching Mengtong;

The characters synonymous with [-] are Arabic numerals, which are commonly used in the Western Regions. Counting is more convenient than other characters. The coins of the Central Bank of Ming Dynasty also have this number. With your intelligence, you must have already distinguished which character is [-]. up;

These are the characters used by Westerners. You need them for steel smelting, and I don’t have time to tell you one by one. When the prince comes later, I will ask him to read them for you. You just need to know how to read them. When the time comes, take some materials back, and memorize them carefully.”

While Zhu Youjian was speaking, Prince Zhu Cihong, Prince Yong Zhu Cijiong, and Prince Ding Zhu Cizhao had also been brought in by Shi Kefa.

In his previous life, Zhu Youjian never played the role of a father, and he didn't know how to raise a good son. Now he basically cultivates them with the mentality of cultivating excellent heirs.

Just like a master leading an apprentice, an old man leads a newcomer.

"Sit down, too. Here, there are no rulers, ministers, fathers and sons. I am just promoting the learning of Taizu. Well, what Song Shilang said is right, this is called holy learning."

Zhu Youjian got up, picked up a brush, and wrote a few words on a piece of rice paper: "General learning can be divided into social science and natural science. The so-called science, you can understand it as learning, studying things. The first is the study of society, and the study of the laws of all things is natural science. The two types of knowledge complement each other, and the yin and yang complement each other, and one is indispensable;

In the pre-Qin period of my China, there were a hundred schools of thought contending, and there were countless famous religions, both of which were ahead of the world, but now, Confucianism is unified, and a hundred schools of thought are dismissed, especially the knowledge related to the national economy and the people's livelihood is even more abandoned, so that our artillery is not as good as Western fans , muskets are not as good as Western fans, have you ever thought that if this continues, even if the Tartars do not destroy our Ming Dynasty in a hundred years, will these Westerners with strong boats and guns also ride on our heads? "

What Zhu Youjian said made Song Yingxing and the three princes stunned. Now they knew that there were Tartar thieves in the north, and when did they notice Xiyangfan.

But because he was in front of the imperial court, Song Yingxing couldn't ask any more questions, so he continued to wait for Zhu Youjian's instruction.

"Since Song Qing is in charge of iron and steel smelting, I will tell you about some chemical knowledge involved in iron and steel smelting. Natural science can be roughly divided into mathematics, physics, chemistry, and biology. Iron and steel smelting mainly involves chemistry. The so-called Chemical nature studies the changes of all things, such as this piece of rice paper, I burned it to ashes, and it changed from paper to smoke and black charcoal."

"And we make iron to turn the impurities in the iron into smoke or invisible gas, and let it escape, so that the iron becomes forgeable steel. This is the chemical formula of iron. The main impurity in iron is carbon, and Phosphorus, sulfur, etc., when calcined with a large fire, can make the carbon react with the oxygen in the air to form carbon dioxide and water. At high temperature, both are gases, and they will naturally escape.

Zhu Youjian wrote down the chemical formulas and reaction formulas of various substances and marked the three states of solid, liquid and gas.

For Prince Zhu Cihong and Yongwang Dingwang, who only listened to the Four Books, Five Classics and history books from the teachers, they are like listening to heavenly scriptures.

And Song Yingxing also had a dazed look on his face, but he was also very interested. He never thought that the essential laws of ironmaking could be studied in this way, which seemed to make him discover another world.

You must know that he used to study everything from the ancient books of the predecessors to find answers or get answers from other people's mouths, but now His Majesty's teachings made him realize that he had fallen into a misunderstanding before, and he did not try to analyze why he insisted on it. Calcined into steel can be used, why the calcination effect is different, the brittleness is different.

Zhu Youjian took down the periodic table of elements and put it in front of Song Yingxing and others: "This table is the key to unlocking the science of chemistry. It covers almost all the material elements that we can see now. The so-called element It is the general term for a class of atoms with the same nuclear charge (that is, the number of protons in the nucleus), and the number of nuclear charges, you may not understand, it also starts with the basic composition of matter..."
