Outside the city of Biandu, the College of Knowledge.

The wisdom of the youth is the wisdom of the country, the wealth of the youth is the wealth of the country, the strength of the youth is the strength of the country, the independence of the youth is the independence of the country, the freedom of the youth is the freedom of the country, the progress of the youth is the progress of the country, the youth is better than the four seas, the country is better than the four seas, the youth is strong in the world, the country is strong in the world...... It's beautiful, my young Song Dynasty, and the sky is not old; I am a young man in the Song Dynasty, and I have no borders with the country.

At the entrance of the entrance of the Seeking Knowledge College is a shadow wall, and a row of inscriptions on the shadow wall is Lotte plagiarizing the later Liang Qichao's "Juvenile Country Sayings".

Yesterday I went to the other courtyard to see the progress of the steam engine and the paddle steamer, and I went out early this morning, firstly, to avoid the harassment of those scholars, and secondly, to inspect the Seeking Knowledge Academy.

"I've seen Master Hou!" Knowing that Lotte was coming, the person in charge of the Quest for Knowledge Academy greeted him at the door early, and when he saw Lotte's carriage, he immediately greeted him.

"Brother Yu, don't be polite!" Le got out of the carriage and hurriedly supported him with both hands.

The person in charge of this knowledge academy is none other than Lotte's old friend Yu Ruozhuo in Pingyu. Because of the relationship between Yu Ruozhuo and Li Bangyan, although he was invited by Lotte, Yu Ruozhuo refused to be an official, and in desperation, Lotte asked Yu Ruozhuo to be the dean of this knowledge college.

After seeing the ceremony, Yu Ruozhuo smiled and said: "Hou Ye destroyed the West and Xia Fangla, and made a world-beating achievement, and no one in my Great Song Dynasty can come out of Hou Ye's right!" ”

Lotte waved his hand and said with a smile: "Don't call the little brother what the marquis, now the little brother and Brother Yu are all white clothes and idle clouds and wild cranes, but they are at ease!" ”

"So those rumors are true?" Yu Ruozhuo was slightly surprised.

"That's all for Moti." Lotte smiled wryly and asked, "How are these students doing in their studies?" ”

The two said as they walked, Yu Ruozhuo said: "According to the plan of the Hou Ye, another group of students were recruited last autumn, and the old students who beckoned at the previous year were willing to work hard and endure hardships. ”

After talking about the situation of the Seeking Knowledge College over the past year, Yu Ruozhuo asked very puzzled: "Hou Ye runs a school not only does not collect points, but also manages food and housing, and also distributes clothes every season, which has cost a lot of money in the past two years from the previous year to the present year, is Hou Ye doing charity?" ”

didn't answer Yu Ruozhuo's question, Lotte just smiled and said, "In a few days, I will invite Brother Yu to the boat for a drink!" ”

"Could it be that the Hou Ye has lost his official position and is depressed, and he wants to learn from the cynicism of the Shenzong Dynasty?" Hearing this, Yu Ruozhuo was shocked, and hurriedly persuaded: "Hou Ye is suitable for the emperor Ji Gui as the emperor's son-in-law, although there is a political view and the Son of Heaven is different, but also take into account the identity, flowers, streets, willows, lanes, green, buildings and other places, and Hou Ye's identity is really inconsistent, besides, what Wang Yu did back then was mostly criticized by later generations, and he was really afraid of being a brother......

Hearing Yu Ruozhuo's words, Lotte laughed: "What Brother Yu said, the younger brother is not taking Brother Yu to drink on a flower boat, the younger brother is going to take Brother Yu to a wonderful boat, this boat does not need manpower to row or be driven by wind, and can automatically drive on the water......"

"Master Hou, don't coax me to ......" Yu Ruozhuo couldn't believe it.

Lotte said very seriously: "Tomorrow, tomorrow by the Bianhezhou Bridge, the younger brother will prepare a wine feast on the boat to welcome Brother Yu, Brother Yu should not miss the appointment!" ”

"Really?" Yu Ruozhuo didn't look like Lotte was joking.

"A gentleman's word!" Lotte nodded.

Knowing that Lotte was not joking, Yu Ruozhuo nodded and said: "That's good, I won't see you tomorrow, and I can borrow the light of the Hou Ye for my brother!" ”

After the agreement, Lotte got to the point: "These children are from poor backgrounds, and they are destined to be unable to enter the public service without education, and I take in these children to let them become literate and train them to become skilled craftsmen with skills, even the kind that is not inferior to the public loss class." ”

For Lotte's statement, Yu Ruozhuo agrees very much, as the so-called teaching people to fish is not as good as teaching people to fish, there is a craft, and you can eat enough anywhere.

Suddenly, Yu Ruozhuo came to his senses, looked at Lotte and said, "Master Hou, don't you let these children learn something, or do you want to do the kind of boat that you said that neither needs manpower to row nor need wind power?" ”

Lotte smiled: "Not only a boat, but also a car that doesn't need a horse-drawn car in the future, and a machine that can even fly to the sky!" ”

Yu Ruozhuo was surprised, but he couldn't think of what Lotte was talking about, and his heart wanted to get better.

Lotte continued: "When the first batch of children have all the words and learned the things of the Ten Chapters of the Sutra, I will get some interesting things to study for them, and then I am afraid that Brother Yu will be surprised when you see these things!" ”

In addition to the specialization in art, in the Northern Song Dynasty, a dynasty with underdeveloped science, it was very good for ordinary people to be literate and look up numbers, but Lotte knew that only these children must be proficient in arithmetic and learn topics such as geometry and algebra in the manufacturing industry.

As the saying goes, science and engineering are not separated, those engaged in engineering need strong scientific knowledge to support, and those engaged in science are indispensable for engineering, and the two complement each other and are indispensable. But Lotte also knows that when the contents of the books such as "Nine Chapters of Arithmetic", "Zhou Ji Sutra", "Island Sutra", "Wucao Sutra Sutra" and "Fixation" of the "Ten Books of Calculation" are taught to these children, they can pick out the best among these children.

At that time, it was the time to pick out the best students and serve as the backbone of the school in the future, so that the Great Song Dynasty appeared as the prototype of education in later generations.

In fact, this is a layout of Lotte, the emergence of the steam engine will give birth to the development of the productive forces, the advent of the Age of Discovery, will make a part of the people quickly become rich and become the first group of capitalists, when the relations of production do not adapt to the productive forces, the landlord class begins to decline, the capitalists rise, and the advanced modern science that helps the development of the productive forces will undoubtedly be used by the bourgeoisie to replace those feudal economic and righteous knowledge that does not help the development of the productive forces.

The manufacture of artillery, steam engines, and other machines is fundamentally inseparable from the application of mathematics in technology.

"Master Hou is erudite, Yu is absolutely impossible!" Yu Ruozhuo was confused when he heard it, so he had to say.

The fact is that when Yu Ruozhuo heard arithmetic, his heart was also very frightened, although arithmetic is not the content of the scientific examination, but all those who read well know that those who are proficient in arithmetic are undoubtedly the smartest kind of people, and they must not be underestimated.

Turning the conversation to the point, Lotte said: "Brother Yu, you must not only pay attention to the academic performance of these children, but also pay attention to their character, and some people with poor character will be expelled from the academy!" ”

"Those who skip classes without reason, those who fight, steal, and those who do not respect teachers and elders are all expelled from the school!" Yu Ruozhuo said, paused and continued: "Master Hou, I want to increase the example of these children's Moyi teaching, so as to cultivate the character of these children. ”

Lotte shook his head and smiled bitterly: "It's easy to be pedantic when you read too much Jingyi, and besides, if you look at these big people in the court today, which one of them is not familiar with the rolling melons of the Four Books and Five Classics, and then look at their character, Brother Yu still thinks it is interesting for these children to read Moyi?" ”

Hearing Lotte say this, Yu Ruozhuo also sighed.

In late April, the weather had begun to get hot, and it was impossible to sit in the house, and seeing the teaching gentlemen of the Seeking Knowledge College, Lotte and Yu Ruozhuo came to walk outside, but also to check the situation of the college.

This time I came to the Knowledge Academy to inspect, Lotte was of a surprise nature, but after a turn around the Knowledge Academy, Lotte was obviously satisfied with the Knowledge Academy, the students were very curious, and the learning attitude was correct, and the students in those schools performed too well.

……

In the Great Song Dynasty, iron tools were government-run, and smuggling iron tools was a crime, and the iron used by Lotte to make steam engines was all bit by bit, even bought from the black market, after all, Lotte had not yet touched his hand to the iron ore of the Great Song Dynasty; And gunpowder is a forbidden thing of forbidden things, and like later generations, gunpowder as a dangerous good, in the Great Song Dynasty to make fireworks and firecrackers is to go to the government for the record, and Lotte in the other courtyard to make artillery privately is a taboo.

After inspecting the Quest for Knowledge Academy, Lotte immediately came to the hidden courtyard where the artillery was made. Because it is taboo, this courtyard is the most heavily guarded, but it looks loose on the outside, but in fact it is tight on the inside, and outsiders are watched by secret sentinels from miles away, and if these people still want to get closer, they will be subjected to all kinds of unexplained difficulties and provocations.

When you enter the gate of the workshop, you can see that there are many large and small cannon barrels in the courtyard, some of them are made of iron and some of them are made of copper, some of them are cracked into several pieces, and some of the faces are covered with cracks, so that you can't even see the original appearance without looking closely.

"I've seen Master Hou!" Someone reported that Lotte was coming, and all the craftsmen in the workshop came out to greet him.

After the politeness, the old man Wang who was in charge of the workshop said ashamedly: "Master Hou, the little old man is incompetent, in addition to using copper to make the cannon body, the little old man tried to smelt molten iron to pour the cannon body, but found that these cannon bodies made of iron could not withstand the explosive power of gunpowder at all, that is, the best cannon body will crack to varying degrees after letting go of dozens of cannons, and some will even have accidents that blow up and hurt people." ”

A craftsman next to him also said: "Master Hou, the cannon bodies that exploded with explosives outside are the results of the test." ”

Copper is too expensive to match iron, and it is not always a way to use copper to make cannons; But using iron to make cannons, the quality of iron is not up to par, as for using 100 steel to smelt and cast cannons, the steel and copper are still expensive, and after melting, the toughness of iron will be greatly reduced, and the effect may not be copper.

Lotte shook his head and smiled: "Master Wang doesn't need to blame himself, the reason why these iron cannons have failed repeatedly is nothing more than that the quality of the iron produced in my Great Song Dynasty is not good, and the current technology of smelting steel is still too low." ”

There is no way, the iron ore of the Great Song Dynasty is not good, and it contains too many impurities, and the metallurgical technology of the Northern Song Dynasty cannot solve the problems encountered now. As for all the steel of the steam engine, the steel hammered by the blacksmiths is natural, although the texture of ordinary steel can be compared, that is, the power of the waterwheel drives the hammer to replace the manual hammering, but the cost is still high.

After a pause, Lotte continued: "In view of the fact that I have too many iron impurities in the Great Song Dynasty, it is difficult for the iron artillery to fire for a long time, and my heart has been confused for a long time. ”

Hearing Lotte say this, the eyes of all the craftsmen widened in unison, and their eyes flashed with good eyes.

Clearing his throat, Lotte said: "Although it is still two to say whether this cannon will succeed or not, Le Mou has given a nice name to the iron cannon he envisioned, calling it 'sub-mother cannon'!" ”
