Approaching the end of the year, the nobles of Chang'an City are busier than usual.

In the house, Mrs. Fang was also receiving relatives from Fan Yang's hometown.

"Auntie, this time the family sent someone to send Shengzhi to Chang'an, in fact, I mainly heard about Sun Simiao's fame, and I hope to find him to see if I can cure Shengzhi's stubborn disease."

A personable young man with a child sat in the lobby, talking to Mrs. Fang and Fang Zhizhi.

"Lu Xuan, I heard that Shengzhi has been smart and clever since he was a child, and this time he came to Chang'an, why don't he just live at home. In Chang'an City, no matter what you want to learn, you can find better teachings. ”

Fang Yizhi looked at the somewhat thin child, and there was a hint of love on his face.

"Yes, Shengzhi is now eight years old, which is exactly the age to enter Mengxue and go to school. In Chang'an City, no matter which Mengxue you go to, it is better than returning to Fanyang. ”

Mrs. Fang also expressed her views in a timely manner.

This child, Lu Zhaolin, is the son of his cousin.

The face is handsome, and his eyes reveal a resolute look, although he doesn't talk much, but occasionally a few words make people feel that he is still a child.

Fang Yizhi had never seen such a child, and he was also full of interest in him.

"My cousin is now an official in Jiangnan, and this time I wanted to bring him to office. However, it was because of the stubborn illness that the idea was canceled. My aunt has this proposal, and I think it's good. Ascension, what do you think? ”

Lu Xuan also felt the extraordinaryness of his cousin during this time, otherwise he would not have consulted a child here.

"I have heard for a long time that there are three major academies in Chang'an City, and there are countless primary schools and Mongolian schools, and I want to see and see it for a long time, and I will talk about my aunt and brother Zhizhi in the future."

Lu Zhaolin was not polite.

Originally, when he set off from Fanyang, his family had already considered letting him stay in Chang'an.

Now it is nothing more than to see whether to stay in the Fang Mansion or stay in the Lu family's other courtyard in Chang'an City.

"Auntie, I'm going to play with the little corn!"

At this moment, Fang Yiyu jumped out of the door.

Under the leadership of his son, Fang Yiyu is now also a frequent visitor to the Chu Palace.

Today, she made an appointment with Little Corn, Son, Cheng Mei and others to go to Baicao Garden to play snowman.

Unexpectedly, I was about to say goodbye to my mother, but I found that my mother was meeting guests.

"Yiyu, come and get to know Shengzhi, this is your cousin, you just took him to Chang'an City to get acquainted with him."

Among the houses, the closest to Lu Zhaolin's age is Fang Yiyu.

Besides, Mrs. Fang also wanted her nephew to be close to the Chu Wangfu.

The Yongping County Lord's Sect Luo Bin Wang has made a lot of fame in Chang'an City this year.

Even, taking this opportunity, maybe it can ease the relationship between Fan Yang Lu's family and the Chu Palace.

Otherwise, if they all want Lu Xuan to have no contact with the Chu Palace, this is not the situation that Mrs. Fang wants to see.

"Okay, then come with me."

Many people are more lively, but it doesn't matter if Fang Yiyu is left.

……

In the palace of the king of Chu, Li Kuan was tinkering with something in the study alone.

"Lord Wang, you've been busy in the study for two days, why don't you eat some snacks and take a break."

Wu Meiniang came to Li Kuan's side with a cup of hot tea and doughnuts.

In the entire palace, the only people who can freely enter and leave Li Kuan's study are her and Cheng Jingwen.

Well, maybe a little corn will have to be added.

"Come, Mei Niang, I just want to discuss something with you."

Li Kuan put down the pen in his hand and looked at the drawings on the desktop with a little worry.

I searched all the modules of the system, but I couldn't find any books or technical information about the steam engine, and the only thing I could see was that there were a few pictures of the steam engine in the textbook of the nine-year compulsory education awarded.

You can't build a steam engine just by relying on these pictures.

In the past two days, Li Kuan racked his brains to sort out the knowledge related to the steam engine that he knew, and prepared to build a steam engine research institute in Guanshishan Academy and began to study the steam engine.

After several years of development, there have been a lot more workshops in Chang'an City, and the number and status of craftsmen have also risen significantly.

It's time to start thinking about getting the steam engine out of the way.

With current technology, it will take at least two or three years to develop a commercial steam engine.

If you don't start to prepare, then the situation of manpower shortage in Datang's various workshops is estimated to be more obvious.

After all, the new population, even if it is fast, is still largely a child.

It's not very useful for a short time.

"Lord Wang, is this what you want to discuss?"

When Wu Meiniang put things down, she saw those drawings on the desktop at a glance.

However, no matter how smart and clever she is, she can't figure out what Li Kuan is painting for a while.

"That's right, when Ben Wang gave a lecture to the students at Guanshishan Academy before, he mentioned an interesting scene in life, that is, when boiling water with honeycomb coal, once the water in the pot is boiled, the lid of the pot will be constantly opened, what does this mean?"

"Does it mean that water vapor also has power?"

Wu Meiniang replied tentatively.

"Yes and no. The water vapor itself is certainly powerless, but if you keep boiling the water, the water vapor in the pot will increase, and if you can't find a place to excrete, then the pressure in the lake will increase, and the lid will be lifted. That's what you say about water vapor also has power. ”

"It's true, there is more and more steam in the pot, and if there is no vent, it may explode."

Although Wu Meiniang didn't quite understand why Li Kuan told her about this, she also sat aside and chatted.

"A small kettle can generate that power. If we can produce more water vapor and use more robust containers to load this water and steam, can we use the power of this water vapor through some special institutions? ”

"Lord Wang, is this strange thing on your drawings a new device on how to use water vapor?"

Wu Meiniang's eyes lit up and she looked at the drawings on the table again.

Although she still didn't understand what the impact of this equipment would be, if she could push some machines to operate without manpower and rely on the power of water vapor alone, then it would be of great significance to the workshops under the Chu Wangfu.

As the main person in charge of the business of the Chu Palace, she has a deeper understanding of the manpower tension.

The most important thing is that if you have equipment to replace manual work, you don't have to worry about personnel fatigue.

The paper workshops and honeycomb coal workshops under the Chu Wangfu are the most in demand for this aspect.

"That's right, this is the steam engine that the king envisioned, but how to make them and how to use them still needs to be carefully studied.

I plan to let Dai Quan take the lead in the research and development, and set up a steam engine research institute in Guanshishan Academy to cooperate with it, so that those students of Gewu Academy and craftsmen from various workshops will work together to develop this steam engine, and strive to achieve mass production as soon as possible. ”

From the perspective of later generations, the early steam engine actually did not have much technical content.

But from the perspective of the fourteenth year of Zhenguan, any part of the steam engine is full of difficulties to make.

Not to mention the rest, to transfer steam, there must be a high demand for tightness, how to solve this problem, it is enough for craftsmen to drink a pot.

"Dai Quan is the only eighth-level worker in the palace, and he is very proficient in many crafts, so it is only fitting that he is in charge of this project. However, if this steam engine is to be able to exert its power, the volume must be very large, and it must be very complicated to make, Mei Niang feels that she still needs to give them more time. ”

Dai Quan is now Wu Meiniang's right-hand man, and any technical problems encountered in the workshop can basically be solved by finding him.

So Wu Meiniang rarely said a word for him.

"Of course, the king didn't expect them to get a steam engine out next year. Throwing this thing out now is to let the teachings and students of Gewu Academy first enrich the theory of the construction of the steam engine.

At the same time, we began to prepare a specific design, and first made a prototype to know whether the theory was correct or not, and where it needed to be improved. As long as they can make a truly usable steam engine within three years, the king will be very satisfied. ”

Li Kuan, better than anyone else, understands the reason why scientific research is not in a hurry.

Unless one day the system mercifully rewards him with a copy of the steam engine technology, it is essential to spend several years developing it.

Not to mention three years, in fact, even if it was successfully developed within five years, Li Kuan felt that it was not slow.

After all, this is an epoch-making product.

When Datang will start to enter the industrial revolution, it depends on when the steam engine will be mass-produced.

……

In the Baicao Garden, Lu Zhaolin looked at the youngest little corn but led a group of people to build a snowman like a leader, and felt that the scene was a little weird.

Cheng Mei and Cheng Lan forget it, but the difference between the left and right is only one year old.

But like Princess Jinyang and Fang Yiyu, they are obviously much bigger than Xiaocorn, and they actually revolve around her.

"There are no tigers in the mountains, and the monkeys are kings."

As soon as Lu Zhaolin said this, a group of young ladies who were building snowmen immediately paused.

"Smack!"

Xiao Corn directly grabbed the snowman's big nose and threw it at Lu Zhaolin.

"Lu Zhaolin, what do you mean. Are you calling me a monkey? You're the monkey, you sharp-beaked monkey-cheeked fellow. ”

The son was also very unhappy and said: "Fang Yiyu, where did you find such a strange thing, why haven't I heard of such a number one person in Chang'an City before?" ”

"Don't be rude. I don't want to apologize to everyone yet. ”

Fang Yiyu looked at Lu Zhaolin a little embarrassed.

This little cousin, Fan Yang came over just now, and he thought that Chang'an City was Fan Yang, and the Lu family had the final say on everything.

He hasn't seen the power of a golden retriever yet, has he?

"Only women and villains are difficult to raise. I didn't say anything wrong, so why apologize? ”

At this time, Lu Zhaolin has not experienced the beating of society, and he has been proud since he was a child.

Even if it was a group of princesses, county lords and daughters of the national princess in front of him, he didn't take it seriously.

Fan Yang Lu's is so tough.

"Hmph, you're stupid at reading, aren't you? Let me ask you, two snowballs, one large and one small, land at the same time, which snowball lands first? What color does the red and yellow dye turn into when they are mixed together? Don't know, right? Xiao Ma felt that he wanted to teach Lu Zhaolin some lessons, and immediately crackled out a bunch of words.

"Let me ask you again, you can eat courgette and winter melon, but what melon can't be eaten?"

"Haha, I don't know, I'm a fool!"

"Let me ask you again, what is the narrowest road?"

"Don't you understand again, do you? The road is narrow. ”

"Why can't you break an egg when you beat it with a hammer? Got it? ”

Fang Yiyu threw out a few questions one after another, and immediately asked Lu Zhaolin.

"Hmph, how can you beat an egg with a hammer without breaking?"

Lu Zhaolin has never been swept away like this since he was a child, and he feels a little unbearable on his face.

If this is compared to the Four Books and Five Classics, he will definitely kill the audience in seconds.

As the most famous little genius of Fan Yang Lu's family, Lu Zhaolin has already started to learn these classic books early.

And because he has the ability to almost never forget, even the jerky "Analects", he can almost memorize it backwards.

But now the problems thrown by the little corn are all things he has never encountered before.

For a moment, he really couldn't react.

"Hee-hee, hit the egg with a hammer, of course the hammer won't break."

Seeing Lu Zhaolin eating deflated, Xiao Ma quickly forgot about the unhappiness just now.

This little girl, the anger comes and goes just as fast.

Lu Zhaolin: ......

"Little corn, we should find an opportunity to take him to the laboratory of the Gewu Building of Guanshishan Academy to have a look, some people in the province always don't know how thick the sky is."

The son felt that although Lu Zhaolin was suspected of scolding Xiaocorn for being a monkey just now, he also despised himself, so he also added a fire to the side.

"I don't think I need to go to Guanshishan Academy, call my second senior brother over, and let some people know why the flowers are so red."

Xiao Ma felt that this Lu Zhaolin was too arrogant, and it was not very pleasant to watch.

In Chang'an City, people who dare to be so arrogant in front of Xiao Corn have now been educated by her with a golden retriever.

For the sake of Fang Yiyu's face, Xiao Mao didn't have a plan to let the golden retriever bully Lu Zhaolin today.

"What you just asked is all the evil things of the side, if you have the ability, you can compete with me with the content of the scriptures in a dignified manner, who is afraid of whom."

Lu Zhaolin felt that he had just been swept away by the little corn, and he was also unhappy.

"What kind of skill is it to only learn? My second senior brother is much more powerful than you in scripture, arithmetic, law, and even medicine. ”

After Xiao Ma finished speaking, he didn't build a snowman anymore, and prepared to leave directly.

However, when it comes to Cao Cao, Cao Cao will arrive.

"Who praised me so fiercely there."

At the gate of Baicao Garden, Di Renjie walked in with Liu Yuan.
