Chapter 23: The Practical Significance of Strength

A person who knows that he is doing something bad and is ashamed of it is already a person who can be saved in many cases.

Because, as long as you turn the page of the history of the seventeenth century, people will find that this is the fastest and most vigorous period in human history, and in the same way, this history is also the eve of human beings beginning to truly understand themselves and know themselves.

Before that, human beings generally belonged to gods or to kings.

I don't have an accurate understanding of myself.

Seeing that astronomical observations were becoming more and more sophisticated, and it became urgent to calculate detailed trigonometric tables, Yushan scholars began to make sine, tangent and secant tables every 10", all by hand, and finally completed the calculations after five years.

Yushan scholars have not only made certain achievements in the exploration of astronomy, but also made a series of achievements in algebraic equation theory.

Song Yingxing and others successively discovered and improved the universal solution method of cubic and quadratic equations, and used imaginary numbers for the first time.

This is the biggest breakthrough in algebra since the Greek Diophantus.

The Frenchman Veda who fled from France to the Ming Dynasty created a large number of algebraic symbols, used letters to represent unknown numbers, and improved calculation methods, which greatly changed algebra.

Due to the fact that Yushan Academy invested a lot of manpower and material resources, Song Yingxing recompiled his book "On Qi and Qi Sheng".

The scientific explanation for the production and propagation of sound is given in the language of science, and he believes that sound is produced by the vibration or rapid motion of an object impacting the air, and that sound is transmitted through the air, similar to water waves.

After inspecting the Yushan Iron and Steel Plant, Song Yingxing re-summarized the deficiencies in "Tiangong Kaiwu", and re-compiled the continuous production process of smelting pig iron and wrought iron (low carbon steel), the steel heat treatment process such as annealing, normalizing, quenching, chemical heat treatment and solid carburizing process.

Through a lot of practice, Song Yingxing finally regarded many chemical elements such as lead, copper, mercury, and sulfur as basic substances, and regarded the substances produced by the reactions related to them as derived substances when describing smelting technology, thus giving rise to the germ of the concept of chemical elements.

The most surprising thing for Yunzhao is that Yushan optical instrument manufacturer Sun Yunqiu made dozens of optical instruments such as magnifying glasses and microscopes, which can be called unique in the world, and the book "Mirror History" has been published in Daming.

And Wang Fuzhi, a great Confucian who was invited by Yun Zhao with a lot of money, did not live up to Yun Zhao's silver coin, and put forward the concept of the metabolism of living organisms in the "Siwenlu Outer Chapter", he said: "The quality is the same from generation to generation,...... The day of muscle is born and the old disappears, and people do not know. Man sees the form unchanged but does not know that its essence has changed......"

Now, work is underway to remove the mysterious words from the text, and when the book is republished, it will become a real scientific work.

Yu Ren and Yu Jie co-authored the book "Yuanheng Healing Horse Collection", which re-expounded the treatment experience of horses, cattle and camels, and won the highest honor in Yushan - the Royal Science Award in one fell swoop.

In the book "The Book of Diseases of the Counties and Counties of the World", Gu Yanwu affirmed that the replacement of the sub-feudal system by the county system is a historical progress.

Although the county system also has drawbacks, it is absolutely not possible to regress and implement the sub-feudal system. Gu Yanwu also pointed out that the disadvantage of the county system is that the imperial power is too autocratic.

Although there are not many words accusing the imperial power, it has also set off a monstrous wave in Yushan Academy, and many people think that such a description is a great disrespect to Yun Zhao.

However, Gu Yanwu didn't care, and swore that not a word would be changed, and after being criticized by many people, Gu Yanwu, who was furious, even added a lot of mistakes made by Yun Zhao since he ascended the throne.

The criticism is extremely spicy, and he also blames all the mistakes made by officials in the world on Yun Zhao, if you only read this book, Yun Zhao is a great dusk king who is far beyond Ji Xuan.

After Yun Zhao saw it, he jumped like thunder, shouting that he wanted to divide Gu Yanwu's five horses...... However, this book, which has added a lot of Zang Wei Yunzhao's "Tianxia Junguo Li Disease Book", was still first published as scheduled.

Because of Yun Zhao's rage, this book was still in short supply after the initial printing of 20,000 copies, so 80,000 copies were finally printed, making it the largest book printed in the Ming Dynasty in China in four years.

At this time, Xu Xiake returned from watching the mountains and devoted himself to compiling his travelogue, and when he was in China for four years, he reprinted his travelogue - "Xu Xiake's Travels".

Mr. Fang Yizhi, a young professor at Yushan Academy, finally published his own work on Gewu, "Physics Knowledge", after studying Gewu for many years.

Among them, in volume 7, he resummarized and summarized the Yushan coke method: "Coal is produced everywhere. Those who stink will be burned and closed. into stone, and then chisel into the furnace, said reef. “

After Yun Zhao saw it, he scolded Fang Yizhi, thinking that what he wrote was obscure and difficult to understand, and the craftsmen couldn't understand it, and the readers couldn't understand it, and they didn't know who it was written for.

Therefore, before Fang Yizhi's book began to be sold, it was taken back by Fang Yizhi and burned, ready to be recompiled and then republished.

The sign of the prosperity of an era is that all kinds of talents emerge one after another, all kinds of discoveries emerge one after another, and all kinds of industries flourish.

Therefore, when Yun Zhao came back from the Yushan Academy Research Results Exhibition, he was in a good mood, even if there was a very unpleasant argument with Gu Yanwu at the venue, overall, he was in a good mood.

Philosophy, arithmetic, physics, chemistry, medicine, agriculture, astronomy, and geography have all made great progress, which makes Yun Zhao have more hope for the future.

The Ming census has ended, and now the total population of Daming is 164.52 million, and nearly 8,000 newborns are born every day, and there are about 3 million new people throughout the year.

For every newborn, Yun Zhao, Qian Duoduo, Feng Ying sent them the most sincere blessings, as long as there is a newborn croaking on the ground, this family will receive three silver coins of breast milk money.

The pharmacy bureau that has long been all over the Ming Dynasty must register every newborn, and all the drugs needed for newborns' illnesses and the cost of diagnosis and treatment do not cost money, and are all supplied by the royal family until the newborn reaches the age of three.

Combined with the policy that both men and women in Lantian have the right to land distribution, the proportion of female babies among newborn babies in the Ming Dynasty has increased significantly.

Today's Ming Dynasty has no shortage of land at all, on the contrary, there is still a large amount of ownerless land that people need to cultivate, so the control of the population is only an impression in Yun Zhao's head, as for others - more children and more blessings, a large population is a manifestation of national strength.

As far as a country is concerned, feeding the army costs a lot of national money, however, this was not the case with the Lantian Dynasty.

From the day the Lantian army was created, the army has always been a profit unit.

And it is the third unit that pays the most money and grain in the Ming sequence.

Although everyone knows that the army does not produce, even the fools know how their money and food come from.

People with guns, cannons, and warships are hardly able to have any other means of production than what they have in hand.

For now, as long as it is not a place where Daming belongs, it is a place where the army makes money.

Again, the Southwest, and the navy, their contribution to the wealth of the army exceeds more than seventy percent of the overall wealth of the army.

At this time, the self-confidence in Yun Zhao's chest had reached its peak.

His huge fleet is sailing the seas.

His massive army was expanding in all directions.

His people were working day and night to produce more wealth for the empire.

His courtiers are working tirelessly for the future of the Empire.

At this time, he, who is the emperor, can naturally rest.

"Still angry with Gu Yanwu?"

When Han Lingshan came, he saw Yun Zhao lying alone on a brocade couch and was half asleep, so he asked with a smile.

"No, I just want to rest, I don't want to rest with anything in my head."

Yun Zhao replied lazily.

"It's time to rest, you see, Li Dingguo has already taken Jinzhou."

Yun Zhao took the military report brought by Han Lingshan and glanced at it and said, "Wu Sangui didn't have fierce resistance? ”

Han Lingshan fart. The stock rested on the desk and lit a flue: "Guanning Iron Cavalry is the fastest, Chu Dayong, who is defending the city, is blown up, and the resistance of the people in Jinzhou City is the fiercest." ”

"Because of our land policy?"

"That's right, Wu Sangui did a good job, telling the people in Jinzhou City that after we came, we would take away the land they had cultivated, take away their cattle, sheep and deer, take their houses, and redistribute them.

Therefore, even if the Guanning Iron Cavalry retreated, they resisted desperately. ”

"How did Li Dingguo do it?"

"At this time, there is no time to reason, so Li Dingguo chose to attack, in front of artillery, those people who want to rely on the big sword and spear in their hands to defend their wealth have no chance."

"Serious casualties?"

"It's very heavy, especially after Zu Dashou forcibly ordered all the people in Jinzhou City to shave their hair, many people feel that there is no way to live."

"Huh? Did Zu Dashou catch it? ”

"No, I ran away with Wu Sangui."

Yun Zhao put down the battle report in his hand and sighed, "Where can he run?" ”

Han Lingshan said: "They are iron-hearted and don't go back to the Ming Dynasty." ”

"I don't want it when I come, just come back."

"Has the messenger of Tokugawa Iemitsu arrived?"

"I'm here, I'm waiting for His Majesty to summon me on the People's Palace Square outside the Congress."

Yun Zhao lazily turned over and looked at Yushan outside the window and said, "You say, how will he explain the invasion of North Korea?" ”

Han Lingshan said, "Any explanation is useless, unless they start attacking Dorgon now. ”

Han Lingshan said with a smile: "The envoy of Tokugawa Iemitsu said that every time His Majesty delays in summoning them, they will cut off the head of a person. ”

"Oh?" Yun Zhao sat up in surprise, he really couldn't imagine the consequences of these people's murder in Jade Mountain.

"Oh, I didn't make it clear, but the head of the envoy, Hatoyama, said that every quarter of an hour, he would cut off the head of a messenger as an atonement."

"Oh, that's fine."

After Yun Zhao finished speaking, he changed to a comfortable position and lay down.
