With a snort, several books were thrown on Liu Minyou's desk, and Chen Xin, who had just rushed back to Weihai, said proudly: "I'll dig up a treasure for you." ”

Liu Minyou glanced at him, picked up a book with two big characters written on it, and said strangely after reading a page: "What's the use of this, I don't believe in religion." ”

Chen Xin came over to take a look, threw it on the ground casually, and then looked at another copy, and it was "The Theory of Fearing Heaven and Lovers", and threw it to the ground, and finally saw a copy of "The Most Illustrated Illustration of Far Western Strange Instruments", and handed it to Liu Minyou, "This is, look at how many machines." ”

Liu Min looked serious, the more he looked at it, the brighter his eyes lit up, and when he put down the book, Chen Xin said proudly: "What, this person's name is Wang Zheng, but I dug it up with all my might." ”

Liu Minyou praised: "It's really a talent, these are all written by him?" ”

"This book is said to be dictated by a missionary named Deng Yuhan and written by Wang Zheng."

Liu Minyou and Chen Xin had never heard of Deng Yuhan, and they had no impression of the Jinnige that Wang Zheng often mentioned, in fact, Deng Yuhan was as knowledgeable as Matteo Ricci, and he was already a famous scientist in Europe before coming to China. He is a Swiss, studied mathematics, medicine and philosophy in German universities, and is fluent in Latin, Hebrew, French and other eight languages, about the late Wanli period, and was selected to enter the Bobcat Academy in Rome, Italy is the origin of the Renaissance, at that time was the center of modern science in Europe, the best scholars can be selected into the Bobcat College, Deng Yuhan is the seventh member of the Bobcat College, and his predecessor is the famous Galileo, where Deng Yuhan exchanged a lot of modern scientific knowledge and methods. He is very familiar with Kepler and others, and is quite famous in the European scientific community.

Later, he met in Lisbon who was looking for books everywhere, and Jinnige was preparing to open a church library in China to promote the development of Catholicism in China, so Deng Yuhan came to China with Jinnige in the first year of the Apocalypse, and Wang Zheng knew him in the fifth year of the Apocalypse, and then followed Long Huamin, Deng Yuhan and others to study Western scholarship and Catholicism.

The Ming Dynasty's tolerance for Western learning was far greater than that of the later Manchu Qing Dynasty. It was a fashion in the scholarly class, not a whim of a few, although Deng Yuhan was also impeached by the Ministry of Rites for spreading Western anatomy. But it did not affect his work, and even in such an important aspect as the calendar, the Ming court also accepted Western scholarship. In the second year of Chongzhen, Emperor Chongzhen specially opened a calendar bureau to prepare these missionaries to formulate a new calendar, and Deng Yuhan has been working in it, but unfortunately Chongzhen has died of illness in Beijing in three years.

"It's very rare to be able to translate like this, how are you going to use this royal sign?"

Chen Xin said: "Set up a workshop and let him guide those young craftsmen......"

"No, no, that's not right. You can't just do the work of a craftsman, you read the book. Liu Minyou turned a page, "You look at the interpretation of these pulleys, 'a single pulley can lift half a full force', fifty-seven to sixty models." It is about the force under the ratio of different wheel radii and shaft diameter, which is completely different from our craftsmen who only know the machine, this pulley is also used by our sailors and tunpu, and we know that it can save effort, but no one has studied how much effort can be saved, and no one can write it. That's the difference. ”

Chen Xin actually didn't look at it carefully at all, and blinked: "Then how do you say to use it?" ”

Liu Min did not answer him directly, but continued to turn to the front, pointing to the picture, "This page is the explanation of the lunar eclipse, although it is still the geocentric theory, but the position of the sun, the earth, and the moon is clearly marked, 'the earth and the sea are combined into one ball, the sun passes over the earth, there is a shadow, and the shadow meets the moon is a lunar eclipse', there is already an understanding of the movement of celestial bodies, and the twenty-seventh paragraph in the first volume says, 'Each perpendicular line must reach the center of the earth, so the end of each perpendicular line must be in conjunction with the center of the earth', although the source of gravity is not clearly stated, but there is already the concept of gravity. In addition, there are Pythagorean law, pinyin, horizontal plane, water pressure, rod principle, gear, object density, lifting, finding the center of gravity of a triangle, and finding the multifaceted center of gravity. This can be used as a teaching material for the popularization of science. ”

Chen Xin said tentatively: "Then, what are you going to ......?"

Liu Minyou rubbed his hands, a little excited, "To run a school, it's called a science and technology school, I will select a group of qualified students and literate craftsmen to learn, not limited to making machinery, I will discuss it with this Wang Zheng again, and add some junior high school knowledge to it." ”

After he finished speaking, he went to get other books, one of which was "Taixi Human Anatomy" introduced the Western human anatomy, which was also written by Deng Yuhan, and there were several other books such as "The Diagram of the New System", "The Measurement of the Heavens", "The Great Measurement", and "Western Yinjue", Liu Minyou kept them, and the other "Western Confucian Books" and "Seven Grams" were also thrown aside.

The most useful in it is still the "Far West Strange Instrument Illustrated Catalogue", which is divided into three volumes, the first two volumes focus on scientific principles, and the third volume is the machinery of the West, and the tools for taking water alone include siphons, crane drinks, dragon tail cars, windmills lifting water, etc., all kinds of water, wind power, and animal power machinery, and gear transmission is widely used, and the whole book is illustrated and illustrated, and the explanations are clear.

A lot of the content in it made Liu Minyou have a new understanding of the scientific level of this era, and at the same time surprised by the progress of Europe, a missionary who came to China already had such a wealth of knowledge, he can know that in terms of scientific theory, the development of Europe has far surpassed that of the Ming Dynasty.

Chen Xin said to Liu Minyou: "Then run a class, but tell you first, it's hard to say how long this Wang Zheng can stay, you have to transfer people quickly, it's best to train a group of teachers to come out, so that you can teach other students in the future." ”

Liu Minyou asked about Wang Zheng's identity, it turned out that he was still a Shangguan, and he couldn't arrange him at will, so he hesitated a little and said: "He's still a Shangguan, so how can he teach others?" ”

Chen Xin said with a smile: "He is interested in these machines and the like, let's make the conditions and funds sufficient, he will definitely be happy, but I also want to put two trainers in, this Wang Zheng will preach as soon as he has the opportunity, let the trainers mix sand, don't bring these students into the Jesuits...... It has been five days since Wang Zheng arrived in Weihai, and he temporarily lives in Zhu Guobin's house. Among all the officers, he was the only one who had not yet married, so Chen Xin was requisitioned together with the maid and the mother-in-law.

In the past few days, Liu Min has accompanied Wang Zheng to visit everywhere, Weihai's clean streets have left a deep impression on him, and the hope exuded by the people has also made him feel completely different from other places, and the brick houses that can be seen everywhere show the wealth here, Wang Zheng has just come from Yangzhou. I used to hear that Wendeng was barren and poor, and the transportation was inconvenient, but now after seeing it, although he didn't feel that Weihai was prosperous, it also impressed him.

He went specifically to see the water camp of the Wenden camp. The sailor wore a dark blue military uniform, and after the regulations began to be enforced, the ship was much cleaner than before. The combat readiness was also very good, and Wang Zheng was very satisfied with the water camp. In addition, he also went to the civil ironware workshop in Mazidun, where there was no relocation, the main production of agricultural tools at present, Liu Min hoped that the farm would be able to sell to other places one day to make money, so he stayed in the Mazidun by the sea, Wang Zheng also had a lot of research on the iron mold method, and discussed it with those craftsmen on the spot, and also demonstrated it in person.

It is very easy to accompany Wang Zheng, and he has high moral requirements for himself. Neither go to the brothel of the Qinglou, nor eat and drink, which makes Liu Minyou have a good impression of Wang Zheng, although Wang Zheng still has some official shelves, but as long as it comes to machinery and Catholicism. I forgot everything.

Early in the morning of the sixth day, Chen Xin personally came to invite him to his official office, which was renovated from the original armor blacksmith's workshop, which was also very spacious, and all the furniture in it was newly bought. It's just that there is no garden, and Chen Xin said that he would do his best to build a big mansion for Wang Zheng, but Wang Zheng said that he didn't care.

Liu Min has his favorite, set up a science and technology school in the workshop, all the tools and raw materials are very sufficient, these students are the most qualified young people selected by the literacy class and the workshop, there is a foundation in literacy and arithmetic, and also has hands-on ability, Wang Zheng is really happy here, with a group of students to teach theory every day, and together to make all kinds of machinery, although a large part of the Far West Strange Instrument Diagram is too complicated, not practical, but Chen Xin and Liu Min did not interfere, Making complex machinery broadens their horizons and cultivates their sensitivity to machinery.

With Wang Zheng's explanation of the theory, this group of craftsmen began to have a group of students interested in scientific theories and methods, Liu Min has high hopes for this class, and often takes time to lecture, these students have strong hands-on ability, he mainly instills in students practical yàn, logical derivation, mathematical methods, analysis and other modern scientific methods, as well as cultivate their ability to lecture, I hope that the students in this class can become the seeds of Wendeng Camp science and technology, with appropriate organization and incentives, to drive the entire Wendeng Camp technology and manufacturing system, In this relatively equal soil of Wendengying, a combination of rational deduction and perceptual experience is derived, and although they still lack philosophical guidance, Liu Minyou believes that as long as there is this seed, it will one day germinate.

In March of the fourth year of Chongzhen, the shape shì was relatively calm, after the beginning of spring, the various tunbao began to be lively spring ploughing, more irrigation wells were drilled, some of which were deep wells, using Wang Zheng's improved windmill to lift water, Wendeng faced the sea on three sides, and the wind was sufficient, so that the impact of drought was greatly reduced.

The drought in the north as usual, the locust plague appeared around the Yellow River basin last year, the drought for many years, the dry land so that the locust laying volume increased greatly, coupled with the changes of the Yellow River, floods, the formation of the alternation of flood and drought disasters, so that along the lake, the coast, the river flood, the waterlogging area appeared many large areas of barren beach or abandoned land, forming the middle and lower reaches of the Yellow River East Asian locust area, the nine sides mainly suffered from the grassland locust plague, this year even near the Beijing division is also a big drought, forcing Chongzhen can only personally ask for rain, He also asked the officials of the ministries to fast for one day in the yamen. Despite this, the drought situation in Shaanxi, Shanxi, Henan and other places has not improved at all, and Yang He's appeasement policy has once again entered a dead end.

At the end of February, the islands off the coast of Liaodong froze, and in early March, a small number of island soldiers from Phi Dao fled, and the intelligence bureau learned from them that the situation on the island was not calm.

After Liu Xingzhi accepted the appeasement last year, he still stayed on Phi Island, and some of the original generals of Dongjiang Town also returned to Phi Dao, using their original influence and family to divide the forces on the island, Liu Xingzhi was originally an outsider, and these old generals of Dongjiang could not be mixed together, plus he did a rebellion again, killed Chen Jisheng, the most prestigious Chen Jisheng in Dongjiang Town, and was always worried about the retaliation of the old soldiers, the two sides were on guard against each other on weekdays, and there was often tension between the two sides, and the hearts of the people on Phi Island were even more discouraged, and Chen Xin was not clear about Liu Xingzhi's final outcomeAfter learning the news, the Intelligence Bureau paid attention to the situation on Phi Island, and the Intelligence Bureau developed a few people who escaped from Phi Island as peripheral intelligence officers, and let them board the merchant ships to trade on Phi Island, while some of the war barracks began to conduct maritime transportation exercises.

In mid-March, Chen Xin received information from the Beijing Division, and there began to be a call in the court to continue to build the Ningjin defense line, because last year's Jiannu entry into the Kou made everyone feel uneasy, and some people set their sights on restoring Guangning, Guangning controlled the border between Liaodong and Mongolia, and the strategic location was very important.

When Sun Chengzong first supervised Liaodong, he sent troops to inspect the old city of Guangning to show the Mongol tribes that the Ming Dynasty still had influence here, which shows the importance of this place.

If Guangning can be restored, the main channel of communication between the Later Jin and the Mongol tribes will be cut off, and the Ming forces will be able to re-influence the nearby Mongol tribes, and the Later Jin will not only be extremely vulnerable to attack on the route of the Later Jin, but will also completely lose suzerainty over the Mongols, and naturally they will no longer be able to enter through the Great Wall.

But this strategic goal is greatly beyond the tactical ability of the Ming army, simply build a Guangning city can not hold, everyone and Jiannu fought for ten years, more or less self-aware, but also know to take it slowly, so there are two voices, one is to the west to restore fù Yi County, through the guò land fortress to build Guangning, the second is to the east, build the right Tun Wei of Guangning, Sun Chengzong agreed with the second kind of eastward development, along the coastline close to the Liaozhong Plain, in case of emergency, you can use the guò sea rescue and transport grain, after consolidation, and then to the north fù Xiping, Zhenwu and other important fortresses, when the time comes to form a fortress group and then occupy Quang Ninh, it is a matter of course.

Although he agreed to the plan to the east, he thought that he could not directly build the right tunwei of Guangning, which was seventy miles away from Jinzhou, and there was a river barrier of the Daling River in the middle. It seems that this plan is closest to the current situation of the Ming army, and it was supported by Liang Tingdong, the secretary of the military department, so the imperial court began to discuss the plan for the construction of the Qianhu House in the middle of Guangning.

Guangning Zhongzuo Qianhu is located more than 30 miles east of Jinzhou, in the middle of Youtun and Jinzhou, and it also has another name, Dalinghe City. rs
