Yang Xuan talked eloquently, looked at the next Song Shihui and suddenly had an idea, and asked with a smile: "Brother Song, you are from Jiangxi, are you from Jiangxi, is Ling Zun okay now?" ”

Song Shihui thanked: "Emperor, thank you for your concern, although my father is over sixty years old, his health is still healthy.

I heard that Long Live Lord pacified Huguang and built the capital of Wuhan, so he came to Wuhan from his hometown, and now he is living in Weichen's house. ”

Yang Xuan laughed and said, "Oh, since that's the case, then Brother Song, please lead the way in front, and I'll go to see Ling Zun."

Ling Zun is a senior master, and I should go to meet him. ”

Song Shihui was shocked: "Long live the lord, this, this, Weichen's humble house is shabby, you go to the Dirty Holy Palace." ”

Yang Xuan shook his head, took Song Shihui's hand and walked out.

After crossing two streets in a carriage, he saw that Song Shihui's family lived in a three-story courtyard house, and Yang Xuan had just entered the gate when he heard the sound of chopping wood inside.

The guards around him were shocked, protecting the left and right respectively, Yang Xuan shook his head, and saw that there were all kinds of things inside, including spinning machines, dyeing machines, blacksmith shops, ......, and all kinds of things.

Looking at his messy face, Song Shihui pleaded guilty: "Emperor, Weichen is out of character, and I hope the emperor will punish him." ”

Yang Xuan smiled and said: "Oh, what a crime, this is your Song family's experimental hall, if I have more such experimental halls, it will be a blessing for the country." ”

Song Shihui shook her head and said with a smile: "Emperor, my father is in the courtyard on the second floor, and he is making things and writing at the same time." ”

Yang Xuan bent down and came to the middle courtyard, only to see an old man in his sixties with white eyebrows looking at a few minerals on the table while writing something in a book.

The old man was so attentive that he didn't even pay attention to the guards entering the courtyard, and he didn't even know that the more than ten craftsmen around him were looking at all this strangely.

Seeing that Song Shihui was about to remind his father, Yang Xuan waved his hand to stop it and stepped forward and said, "Old man, you, why are you in a daze with the ore in your hand?" ”

The old man didn't lift his glasses, looked at the mineral and said, "Hey, here, how is this iron ore different from other places?" You look at the color, and then you look at the other stuff.

The old man has been running south and north for decades, and he has never seen such a strange iron ore. ”

Yang Xuan stretched out his hand to get one, but the old man blocked Yang Xuan's hand and scolded: "Don't touch, don't touch." ”

Seeing this, Song Shihui reminded: "Father, this, this is..."

The old man glared at Song Shihui and said, "No one is allowed to touch the old man's things, you don't know that these minerals are picked up from different places, what if they are messed up?" ”

Yang Xuan smiled and said: "Old man, I have a way, these minerals look similar, we might as well put them in different glasses, and then number them on the outside of the glass, so that we are not afraid of confusion." ”

He glared at Yang Xuan and said, "You, you know at a glance that you are a loser, a glass, a glass costs 100 copper coins, which is too expensive."

Besides, can you know what this mineral is by using a glass? ”

Yang Xuan smiled and said: "Old man, I still have a method, using a magnifying glass, we don't grind the copper mirror into different shapes to artificially enlarge the product, wouldn't that make it clearer?"

We can study the principle of magnifying glasses, we can stack single lens magnifiers on top of each other, and you think, if a single lens can magnify 4 times, then two lenses can magnify 8 times, and three lenses can magnify 16 times, so we can tell what it is. ”

The old man stood up, looked at Yang Xuan in disbelief, held Yang Xuan's hand and said, "The future is terrifying, what you said is reasonable, it makes sense." Shihui, don't we have two good magnifying glasses, put them in a sleeve to adjust them. ”

Song Shihui shook her head, Yang Xuan waved his hand, and Song Shihui ran to find it and handed it to Song Yingxing.

Song Yingxing put it in a sleeve, but because it was very troublesome to adjust, it looked very blurry after adjustment, but it obviously felt much clearer than in the past. ”

Song Yingxing looked at Yang Xuan and said apologetically: "Little brother, your method is very good, but the old man's craftsmanship is too poor, it seems that he has to find a craftsman to help build it, and I will definitely let you see it when the time comes."

Hearing Song Yingxing call Yang Xuan's little brother, Song Shihui was so frightened that she was full of Han and complained: "Father, this, this is the current emperor." ”

Song Yingxing looked noncommittal and said, "Emperor, ....... emperor?"

Frightened and sweaty, Song Yingxing was preparing to kneel down with difficulty.

Yang Xuan hurriedly held on and said, "Old man, don't be polite." I have already promulgated a new etiquette, everyone can meet each other, and you can get to the ground for a long time, and you don't need to kneel. ”

Song Yingxing looked at Yang Xuan puzzled and asked, "Emperor, you don't need to kneel, this, what's going on?" ”

Yang Xuan smiled and said: "Old man, there is nothing to kneel clean in the palace, think about it, if it is on the street, in the field, in the workshop, the ground is not clean, come to a dignitary to kneel once, soiling the clothes is a trivial matter, if you kneel down any nails, it is not good to kneel on sharp stones."

Therefore, in the rules and etiquette of the Chinese Empire, except for the son kneeling to the father and the criminal kneeling to the official, nothing else needs to kneel.

Usually arching your hands and bowing down is the greatest courtesy.

Generally, the courtiers can see me and touch the ground. ”

When Song Yingxing heard this, his eyes were full of praise and said: "The emperor has observed all the people, it is really a blessing for all the people." ”

Yang Xuan patted Song Yingxing's hand and said, "Besides, the old gentleman is our national treasure, I have read your "Heavenly Creation", and many things are very useful."

Since I started the army, I have been able to defeat the enemy on the battlefield, and the old man's "Heavenly Creation" has made great contributions, although you and I have met for the first time, but in fact, you and I have been friends for a long time.

If it weren't for your "Heavenly Creations", and if it weren't for your sons and daughters who contributed to the country, it would be even more difficult to annihilate the Tartars like this. ”

When Song Yingxing heard this, he expressed his gratitude repeatedly.

Yang Xuan said with a smile: "Mr. Song, you said that a lot of your knowledge has been sublimated and developed on Shen Kuo's "Mengxi Writings", which is very good.

I want to establish the National Academy of Engineering according to the model of the Hanlin Academy, and I specially hire you as the president of the Academy of Engineering to preside over the work of the Academy of Engineering. ”

Academy of Engineering? After Yang Xuan's explanation, Song Yingxing was sincerely frightened, and excused himself: "Long live, there are many talents in the country, and the old man has not even taken the Jinshi exam, if he serves as this dean, is it insulting to Sven?" ”

Yang Xuan smiled and said: "The old gentleman is too modest, who doesn't know that you are the third place in the township test Nanzhili, you are much better than me."

You see, I only won the deputy list, and the emperor did it in my township to try the deputy list, why can't the old gentleman preside over the Academy of Engineering? ”

Hearing Yang Xuan say this, Song Yingxing promised to become the president of the Academy of Engineering, and convened everyone to compile knowledge of mathematics, natural science (physics, chemistry, nature), geography and other aspects.

According to the learning characteristics of everyone, the students will gradually teach the relevant knowledge of mathematics, natural science, and geography to the students.

When compiling knowledge of physics, chemistry, and nature, under Yang Xuan's arrangement, Song Yingxing not only had many contacts with missionaries such as An Siwen, Li Zhisi, and Qu Ande, but Yang Xuan intentionally or unintentionally incorporated some knowledge textbooks from his previous life.

For example, Western Arabic numerals are introduced into arithmetic, and concepts such as positive numbers, negative numbers, fractions, and minorities are introduced.

In natural science, Newton's three laws are transformed into the three conjectures of mechanics, and the working principle of levers, the principle of optics, the principle of buoyancy and other knowledge are compiled into the textbook through conjectures and other methods.

Yang Xuan imitated Lü's practice in the Spring and Autumn Period, and asked students across the country to remind everyone to pay attention to the way of directly awarding the title of professor if one of the textbooks compiled by the engineering academy proved to be wrong.

On the basis of receiving advanced natural sciences from the West, it can be said that the mathematics and natural science textbooks published this time represented the world's first-class level at that time, and some of them were decades ahead of Westerners.

While promoting these new natural sciences, Yang Xuan was thinking about whether to establish corresponding scientific research institutes in the future.

Yang Xuan is concerned about the construction of the university and the compilation of teaching materials.
