"Thunder comes from the sky, and where does man-made thunder come from?"

Li Tai muttered to himself, and glanced at his son Li Xin again, who was playing with a wooden hammer and saw something knocking something.

I saw a flash of thunder on the plain in the distance, and the thunder and lightning pierced the earth, and a moment later there was thunder.

I became more and more confused about how to make copper wires generate electricity.

And how does the electricity happen?

The thunderstorm didn't end until midnight, and Yuan Tiangang was sitting in a mansion, with Li Chunfeng sitting cross-legged in front of him.

The two Taoist masters are also thinking about the ultimate problem facing Lishan now, magnet and electricity.

Li Chunfeng said in a low voice: "Daochang Yuan, the people of Lishan are good at argumentation, how to demonstrate the relationship between magnets and electricity?" ”

Yuan Tiangang looked at the book in his hand, "As mentioned in the Lishan scroll, light has a speed of transmission, and sound also has a speed of transmission, but the speed of the two is not the same. ”

Li Chunfeng said again: "Look, Lishan has so much knowledge to demonstrate, but Poor Dao has figured out part of it. ”

"What is it?"

"The Hou of Lishan County said that the earth has gravity, and it can be concluded from the recent that magnets also have gravity, can it be said that the land under our feet is a huge magnet."

Yuan Tiangang slowly opened his eyes and said in a low voice: "This is just speculation, this is not an argument. ”

Li Chunfeng said again: "For Lishan, if you want to argue, you need to have a guess first. ”

The next morning, it rained all night and the drizzle was falling.

Whenever it rains, Lishan always disappears into the mist, and the whole view of the mountain is not clear from a distance.

Lishan was wet, and water droplets kept falling from the eaves, and Zhang Yang looked at the drawings sent by the factory under the mountain.

The steam engine on the drawing has undergone several improvements, and is smaller than the previous one, and will not be built as large as a house.

Zhang Yang revised the drawings and deleted some unnecessary designs.

If you want the steam engine to run more smoothly, don't add unnecessary components.

With a ruler in one hand and a pen in the other, he skillfully sketched on the ground.

After the drawings are drawn, I will go to the workshop to get busy.

Xiao Qingqing sat on the edge of Huaqing Pond, watching his father come out of the study and go to the workshop.

After a while, Niang also came out of the house and was discussing something with Xiaohui and Aunt Xiaowu.

She propped her chin in one hand, looked at her home, and sighed.

Dongyang walked in small steps, "What do you want?" ”

"Aunt Dongyang, have you ever thought about what kind of person she wants to be?"

Dongyang smiled: "Be a good person." ”

"Well, then I'm going to be a good guy too."

"You." Dongyang said again: "You are different, you are the daughter of your brother-in-law, you have been taught by your brother-in-law since you were a child, and the knowledge you have mastered must be different from ours." ”

"What my father taught and what my mother taught are the same."

"Because it's my brother-in-law's child." Dongyang said in a low voice: "You are different from us. ”

Xiao Qingqing was confused again, looking at Hua Qingchi in a daze, his feet were soaked and wrinkled, so he stood up and planned to sleep for a while.

Zhang Yang was busy in the workshop, turning the structures on the drawings into small parts in equal proportions.

When Xiao Qingqing woke up, he saw a car in front of his father.

The car was a little bigger and smaller than the bear, just knee-high.

Xiao Qingqing was surprised: "This is what my father made for me to play?" ”

Zhang Yang assembled the parts, and the wrench in his hand was screwing the nut inside, "Well, if the role of this thing is played, I'll play with it." ”

"Okay."

She began to look at the car expectantly, and then asked, "Aunt Dongyang told her daughter that I am different from them. ”

Zhang Yang took off his gloves, did some more elaborate assembly and said, "What's the difference?" It's all one mouth, one pair of eyes, and two ears. ”

Xiao Qingqing smiled: "Well, my daughter is the same as them." ”

Xiao Qingqing walked to her mother's side again, "Mother, is there any difference between me and Aunt Xiao Wu?" ”

Li Yue drank tea leisurely, every summer is the most leisurely day in Lishan, and it is a favorite time to be able to calm down and read a book.

Listening to her daughter's words, she explained: "You don't have to be the same as everyone else, and everyone in this world is different. ”

Seeing that she was still a little confused, Li Yue glanced at Xiao Sanqiu, who was still crawling on the ground, and said to her: "Actually, your father is different from others, and different from many people in Datang. ”

"What's the difference between Daddy and others?"

"That's a lot of different statements."

Li Yue talked about the incident between him and Zhang Yang before, Xiao Qingqing listened carefully, and heard how her father fooled Uncle Wei Wang before, she always held her stomach and laughed for a long time.

As the child's mother, Li Yue knows very well in her heart that her son is okay, in fact, her daughter has been taught by Zhang Yang since she was a child.

In fact, this child has a very high level of cognition and learns everything quickly.

If there is a difference, it is a different perception of the world.

In Xiao Qingqing's eyes, the people outside are dull, the world is not sober, the family is a bastard, and the emperor is not a good person.

After a few days of peaceful life, these days there are not so many things to worry about in the DPRK and China, and life is very comfortable.

Zhang Yang hoped that it would be best not to disturb Lishan all the time.

These days, I concentrate on making parts for trains, carefully polishing them in the workshop.

The aunt came with a cart, "County Marquis, this is made by the craftsmen, see if it's right." ”

Zhang Yang took the Lishan ruler, measured it carefully, and said for a long time: "It's not too much of a problem, I'll just get these parts in the future, it's very heavy." ”

Aunt Wang waved her hand and said, "In the past, my aunt went out to fight, and some of them had the strength to get out of the way. ”

Zhang Yang frowned and watched his aunt leave, pushing the parts of this car into the workshop.

Early one morning half a month later.

There was some noise outside the house, "Sister, it's moving!" ”

Careful Ann's voice came.

Xiao Qingqing looked out the door, and the little train began to move, and it was moving along the tracks, spinning in circles.

Plumes of smoke rose from the head of the train.

Zhang Yang took off his gloves and let out a sigh of satisfaction, "Well, it's finally done, and this half a month has not been in vain." ”

The small train clicked constantly, and the bears in the family surrounded them, and Xiong Sansheng's little bear was very lively.

However, these newborn cubs are easy to mistake for bears, and they will sometimes follow Bear 2, or Bear 5 and Bear 6.

They are all about the same size, which causes the aunt to often admit mistakes.

The train stopped after more than ten laps, and Zhang Yang cooled the train with water, and it could only be used after drying.

"Dad, why don't you move?"

Zhang Yang put the small train into the cart, "This is for the factory, let them study it themselves." ”

Then put the rails into the bamboo basket, carry them on your back, and pull the car all the way down the mountain with both hands.

Xiao Qingqing and Xin'an were reluctant, and they were still following behind.

Li Tai stood with several craftsmen, discussing the generator.

Seeing that it was his brother-in-law coming, he stepped forward and said, "Brother-in-law, is it done?" ”

Zhang Yang put down the cart and explained: "This is the model train I made, and the specific principle is similar to the drawing, but when you cast, you have to change the position." ”

After the two children laid the rails, Zhang Yang put the train on the rails, first put a burning wood into the hole above the front of the locomotive, and then poured water into the back of the car.

Then put pulverized coal on top of the locomotive, and when the tea was burned, the little train moved.

Zhang Yang took the drawings and explained to Li Tai, "In fact, the structure is very simple, and the bending amplitude of the copper pipe does not need to be too large. ”

Li Tai couldn't help nodding his head and asked the guards on the side to take notes and write down these words.

The train was moving smoothly, the movement was not so loud, and there was some black smoke coming out of the locomotive.

"In the past, the main problem of our train was that it was not light enough, and I used to think that the inside of the train was too complicated, but after repeated improvements and streamlining, it is much better now."

"So I simplified it a bit, leaving only the combustion chamber and increasing the space for the water tank," Zhang explains. ”

Li Tai frowned and said, "In this way, it needs to be more refined." ”

"Well, it's going to be more troublesome."

"Just leave it to me." Li Tai accepted the drawings, and this time he was more confident.

"How's the electromagnetic research going?" Zhang Yang glanced at the big cylinder on the side, "Did you send out electricity?" ”

Li Tai shook his head and said, "Still not, but after using it for a long time, I found that the magnet no longer absorbs iron." ”

"Brother-in-law, do you say that this electromagnetism is also related to the suction of the magnet?"

Zhang Yang frowned and said, "It's possible." ”

Every creation in Lishan takes time, so do springs, so do steam engines, and now Li Tai wants to generate electricity, which is another difficult problem.

With the mentality of giving it a try, Lishan cannot stand still, but must always move forward.

Li Tai whispered: "The Western Expeditionary Army said that they found a very powerful magnet in the Western Regions, and they have let people dig it. ”

"A very powerful magnet?"

"Well, because of the original expedition to the west, a team of soldiers and horses got lost in the desert." Li Tailai paced back and forth and explained: "They have a compass, but the direction of the compass is wrong, and then they were brought back by the local people from the Western Regions, and this group of soldiers and horses was punished for delaying the military plane, and then returned to Chang'an, and was questioned by the officers and soldiers of the Wei Mansion." ”

"After inquiry, I asked them how they delayed the military plane, and they explained that the compass was broken, and this matter was transmitted to the army, and then I understood the reason, it turned out that there was a magnetic mountain in the Western Regions, but whenever the sword soldiers approached, they would be sucked to the mountain wall."

Zhang Yang frowned and thought.

Li Tai said again: "Since it can be so far away, it is probably a very powerful magnet, this king has sent a letter to ask the people of the Anxi Metropolitan Protectorate to help quarry, maybe a stronger magnet can be used to stimulate electricity." ”

It is not easy to see that a certain voltage is required for the current.

Zhang Yang patted him on the shoulder and said, "I hope." ”

Li Tai looked at the gloomy sky, "Brother-in-law, is that electricity really like thunder and lightning in the sky?" ”

"Well, it glows, but there's not such a big movement."

Li Tai smiled and said: "If Lishan can really make this, then Lishan is really an immortal mountain, and the people of Lishan are immortals." ”

Xiao Qingqing nodded heavily, "Then we are immortals." ”

The power of knowledge is powerful, so powerful that it can go to heaven and sea, and can change heaven and earth.

Now Lishan is still in the most basic stage, and after handing over everything to Li Tai to arrange, Zhang Yang returned to the mountain.

The factory in Lishan is very busy, and there is endless work to be done every day.

When Lishan distributed his property as if he had scattered his wealth, no one knew what else Lishan was busy with.

One by one, screws and nuts were made, and these screws and nuts were the key to the next stage of casting in Lishan.

Recently, there is another group of students in Lishan who have returned to their hometowns after learning technology, and these students are all children of Guanzhong.

Xiao Hui and Xiao Wu were talking to the county magistrates in each county.

The two girls had serious faces, and the tone of their conversation was different from that of ordinary people.

"This year, Lishan will accept 1,500 students, and the quota in each county is still the same, over 13 years old and under 15 years old, a total of 30."

Several counties each pondered the population of their own county.

Xiaohui said: "If there are rich and dissatisfied with recruitment, the quota will be decentralized, of course, since the counties have cooperation with Lishan, we can let you exchange places with each other, but this quota cannot be sold, if there are sales of places for profit, once discovered, no more cooperation." ”

"How so?" The county magistrate of Jing County wiped the sweat from his forehead, "Lishan has given us so much convenience, how can we cut off our own way." ”

"Yes, yes."

Listening to the discussions of several counties, Xiao Wu said again: "In line with the principle of fairness and justice, the treatment of students in each county after admission is the same as that of external recruitment, which is based on the conditions of our limited operation. ”

Xiaohui took over the words and added: "Lishan has never cared about the origin and origin of the students, Lishan plans to choose a site and build a large academy outside, Lishan's land is limited, if the excess land in each county can be used to build the academy, you can write documents and hand them to Lishan." ”

Seeing that these county officials were about to speak again, Xiao Wu interrupted: "The next technical institute should be able to gather 3,000 students, covering an area of about 2,000 acres, and build high-rise buildings. ”

Hearing this request, several county officials were silent again, 2,000 acres of land is not a small amount, not to mention the construction of high-rise buildings.

The county magistrate of Weinan County muttered in his heart and asked, "Who wants 2,000 acres of land to build a house?" Is this going to build a city? ”

The county magistrate of Sanyuan County said in a low voice: "This is to build a city." ”

The remaining county officials also looked awe-inspiring, build a city? A city dedicated to reading and learning about technology?

It sounds incredible.

Originally, each of them was just a small county, and it would be good if it could be managed well, and another city would be built, which would require a lot of manpower and material resources.

These counties suddenly lost interest, and they stopped talking, and everyone reached a consensus that if they built a city on the edge of their own county, and said that they could benefit their own county, future troubles were likely to follow.

If you make a contribution, you may not be able to get it well in the end.

looked at the two girls in front of him, and he didn't say anything good to the counties.

Xiao Wu and Xiao Hui saluted the county officials and left.

The twelve county officials of the twelve counties walked out of the temporary official residence outside Lishan Village.

"Is this matter with Jingzhao Mansion Yin?"

It was the county magistrate of Fuping County who spoke, and this person has never had any opinions.
