"Uh...... Well, now listen to me continue...... Regarding non-ferrous metallurgy, we also got a set of hydrotechnical equipment, hehe......"

An Hengtong smiled when he said this.

"What is the wet process?"

"Hydrometallurgy is a technology that is very suitable for our existing conditions, especially about the production of copper, we Chinese have written this method into the book as early as the Western Han Dynasty, hey? What is the title of the book? ”

At this time, Ren Ke interjected next to him, but he didn't remember the title of the book after thinking about it for a long time.

"It's called "Huainan Wanbi Technique", and the method mentioned in it is the famous bile copper method in the history of human science and technology, and this process principle has been used until modern times."

The answerer was Zhu Beiguo.

"Yes, it's this bile copper method, because this archipelago has a large number of low-grade non-ferrous metal placers, mainly oxides!"

At this time, Cao Limei added another sentence in time, which can be regarded as a note for this bile copper method.

“…… So we only need to use sulfuric acid to heap leach, and then add iron powder to produce copper! And I want to tell you that three hundred years ago, Europeans still didn't know how to do it! ”

"Really? Speaking of which, our Great Celestial Empire is still very good! ”

"Do you know that there is a book called "Heavenly Creation"? In the last years of the Ming Dynasty, Xu Guangqi Xu wrote ......"

"Hey, hey! It's Song Yingxing! Master Xu wrote the "Complete Book of Agricultural Administration" ......"

"Well, anyway, there are all kinds of technical information in there! I highly recommend the business people involved to learn from each other! ”

"Why? What is the use of technology more than 300 years ago for us? ”

"You don't understand that! It's true that it's a technology from 300 years ago, but it's also a technology that completely establishes the industrial system of 300 years ago! Doesn't it make sense for us? ”

"Listening to you say that, it seems to make a lot of sense!"

"In the process of industrial construction, there are many things that we feel are bottlenecks, and sometimes we can't get them out even if we rack our brains, because our ideas are too limited by the industrial conditions of modern society. In fact, there are many industrial raw materials, auxiliary materials and even processes, which can be made using the methods of that era, and the meaning of "Heavenly Creation" lies in this, right? ! ”

"That's right!"

"Makes sense......"

A group of science and engineering men agreed with Zhu Beiguo's suggestion.

However, Zhu Beiguo's words aroused various feelings about this book among the high school students on the other side:

"Hey, I seem to have heard of this "Heavenly Creation" somewhere, it is indeed a very divine book."

"Well, it's a pity for the Ming Dynasty now, in fact, the level of science and technology at that time was not inferior to Europe!"

"yes, except that the weapons are a little behind......"

"Backwardness is also temporary, and later there is an introduction and catch-up, and it may not lose to Europe in time!"

"But it doesn't seem to have been handed down to future generations."

"Really? Why? And then what? ”

"Then the Qing Dynasty came! Emperor Kangxi wisely found that "Heavenly Creations" was not conducive to the rule of Manchuria, so he banned the book. ”

Zhu Beiguo next to him responded.

"Holy! Why? ”

"Isn't that hard to understand? For the Manchus, the Han people with a large population are too smart, and people are guarding against it, not to mention "Heavenly Works", even the Qin Tianjian of the Kangxi Dynasty is controlled by foreigners, and the Kangxi Emperor does not allow Han officials to learn the Western calendar, nor does he allow Tang Ruowang Nan Huairen These foreigners to teach Han officials, the Kangxi Emperor said, Han officials should promote Confucianism, that is the essence of your Han culture, as for what Western calendar, making clocks and watches, etc., it is a strange skill, don't learn it......"

Before everyone finished listening to Zhu Beiguo's answer, many people from the electric drill faction immediately spoke and scolded:

"Kang Mazi is really wise and martial, but these four have to be put in quotation marks, damn a chicken! This product learns all kinds of Western things by itself, but does not let the cultural elites of the Han nationality learn it, which makes it clear that he does not trust it! ”

"The main thing is fear, that the Han elite will rebel......"

"Not only Kangxi, didn't the Japanese shogunate at that time also boycott Lanxue openly and secretly?"

"Holy! Kang Mazi is yin enough ......"

"However, it makes sense that people are yin and yin, the biggest problem is that the elites of our Han people actually believe in his set of words, not only believe it, but also roar and praise the emperor Shengming!"

"yes, that's the root of the problem......"

"In fact, this book has not been lost forever, and Japan has kept the original work until the end of the Qing Dynasty."

"Confucianism? Hehe, those are all doctrines for serving the emperor @. ”

"That's right! Therefore, Confucianism is the garbage that imprisons the mind! ”

"Hey, hey, hey! You can't say the same about Confucianism, after all, it is something that our thousand-year-old traditional culture has come all the way, don't overturn a boatload of people with a rod! At that time, under the rule of the Qing Dynasty, there must have been those who praised the saints, but those were the elites who were officials!

Let me tell you that Neo-Confucianism had already appeared among the people at that time, and it was an innovation of Confucianism, and later generations once talked about its significance, saying that it was comparable to the Reformation in Europe at that time! It's just that after the alternation of the Ming and Qing dynasties, the literary prison flourished, and everyone kept silent, and this neo-Confucianism did not become the mainstream. It's a pity. ”

Zhu Beiguo saw a group of young people scolding Confucianism, and immediately stood up to correct everyone's statement.

Obviously, Brother Zhu has a certain prestige in the group of high school students, and when he heard what Zhu Beiguo said about Neo-Confucianism, everyone gradually quieted down.

"Imagine it, if it were in the Ming Dynasty, where the government and the opposition were fighting and the literati dared to oppose the imperial power, Neo-Confucianism should have become a mainstream consensus.

Historical facts have proved that the emergence of this Neo-Confucianism was indeed of great significance, and later Neo-Confucianism was transmitted to Japan, which made the Japanese cultural class deeply influenced by Confucian culture like a treasure. Japan's Meiji Restoration, those famous figures, such as Yoshida Shoin, Sakamoto Ryoma, Okubo Ritsu, Saigo Takamori and others, including Ito Hirobumi who won the First Sino-Japanese War, are all followers of Wang Yangming, Gu Yanwu, and Huang Zongxi in the late Ming Dynasty, and they are all deeply influenced by Wang Yangming's Neo-Confucianism.

The so-called holding the Analects in one hand and the abacus in the other, advocating the development of agriculture and industry, civilization and enlightenment, later the Japanese themselves admitted that this Neo-Confucianism was indispensable! It's a pity that it has been in decline for more than 100 years in its birthplace, and it was not until the Qing Dynasty had to engage in the Westernization Movement that it was gradually remembered by the Chinese people. ”

"New Confucianism?"

"Can it be compared to the Reformation?"

"What is this neo-Confucianism, so powerful?"

Seeing that a group of high school students were still confused, Zhu Beiguo had no choice but to continue to explain patiently:

"At this time, the Ming Dynasty, that is, we have a high probability of passing through the past era, the commodity economy and overseas trade are indeed quite developed, which has led to the germ of some kind of social transformation in Chinese society, and at that time, 'Neo-Confucianism' came into being, and the representative figures are Wang Yangming, Gu Yanwu, Huang Zongxi and other enlightenment masters.

An important enlightenment of Neo-Confucianism is to question imperial power, encourage pragmatism, and even have some shadows of European enlightenment thought, because these people are not officials in the imperial court, and belong to the 'public knowledge' of that era, because they are not royal literati, they have no power and power, so they have no public discourse, and they are suppressed and ridiculed by the mainstream consciousness everywhere. ”

"Yes, there are people like Xu Xiake Xu Guangqi, who also started the study of natural sciences by literati, especially Xu Guangqi, who advocated the study and research of Western science. At that time, the great enemy was at present, and the Ming Dynasty implemented the doctrine of taking Western technology, which was actually shortening the gap, but it was a pity that the Ming Dynasty had exhausted its ......."

At this time, Xu Zhi also interjected beside him, and then Wei @ Hong on the other side sighed and said:

"Hey! Chongzhen is a pity, so diligent! Still so thrifty......"

"It's just that thrift and diligence have a! If you can't do it with ability and knowledge, the more diligent you are, the greater the harm! ”

Ren Ke next to him shook his head and responded to Wei @Hong's statement with disdain.

"Well, in fact, Chongzhen is really not as good as his brother, the Emperor of the Apocalypse knows that he doesn't understand anything, and he is not interested in governing the country, in order not to delay the country's major affairs, he simply handed over the government affairs to Wei Jiuqiansui, and he went to be a carpenter freely, in fact, from this point of view, Brother Tianqi is not too bad an emperor......"

Lawyer Li Junming obviously read some history as well, and immediately nodded in agreement with Ren Ke's statement.
