"Thunder comes from the sky, where does man-made thunder come from?"
Li Tai murmured to himself and glanced at his son Li Xin again. He was playing with a wooden hammer, hitting whatever he saw.
I saw a flash of lightning on the plain in the distance, and the lightning struck the ground, and a moment later I heard the sound of thunder.
I became more and more confused about how to make copper wire generate electricity.
How does electricity occur?
The thunderstorm lasted until midnight. Yuan Tiangang was sitting in a house, with Li Chunfeng sitting cross-legged in front of him.
The two Taoist priests are also thinking about the ultimate problem Lishan faces now, magnets and electricity.
Li Chunfeng whispered: "Master Yuan, Lishan people are good at demonstrating. How should we demonstrate the relationship between magnets and electricity?"
Yuan Tiangang looked at the book in his hand, "It is said in the Lishan Book that light has a propagation speed, and sound also has a propagation speed, but the two speeds are not the same."
Li Chunfeng said again: "Look, Lishan has so much knowledge to demonstrate, but Pindao has figured out part of it."
"What is it?"
"The Marquis of Lishan County said that the earth has gravity. From recent events, we can conclude that magnets also have gravity. Can we say that the land under our feet is a huge magnet?"
Yuan Tiangang slowly opened his eyes and whispered: "This is just a guess, this is not an argument."
Li Chunfeng added: "For Lishan, if you want to prove something, you need to guess first."
Early the next morning, Guanzhong was wet after a night of rain, and drizzle was still falling.
Whenever it rains, Lishan Mountain always disappears into the mist, making it difficult to see the entire mountain from a distance.
Lishan was wet, with water drops constantly falling from the eaves. Zhang Yang looked at the drawings sent from the factory at the foot of the mountain.
The steam engine on the drawing has been improved several times, and its size is smaller than before, and it will not be as big as a house when built.
Zhang Yang modified the drawings and deleted some unnecessary designs.
If you want your steam engine to run more smoothly, don't add unnecessary components.
Holding a ruler in one hand and a pen in the other, he drew skillfully on the ground.
After the drawings are finished, go to the workshop and get busy.
Little Qingqing sat by the Huaqing Pond, watching her father come out of the study and go to the workshop.
After a while, my mother came out of the house and was discussing something with Xiaohui and Xiaowu.
She held her chin with one hand, looked at her home, and sighed.
Dongyang walked over in small steps, "What are you thinking about?"
"Aunt Dongyang, have you ever thought about what kind of person you want to be?"
Dongyang smiled and said: "Be a good person."
"Well, then I also want to be a good person."
"You." Dongyang said again: "You are different. You are the daughter of my brother-in-law. You have been taught by your brother-in-law personally since you were a child. The knowledge you master must be different from us."
"What dad taught is the same as what mom taught."
"Because he is my brother-in-law's child." Dongyang whispered, "You are different from us."
Xiao Qingqing was confused again. She looked at Huaqing Pool in a daze, and her feet were wrinkled by the soaking. Then she stood up and planned to go to sleep for a while.
Zhang Yang was busy in the workshop, making the structures on the drawings into small parts in proportion.
When Xiao Qingqing woke up from her sleep, she saw a small car in front of her father.
This car is smaller than a bear, just reaching knee height.
Xiao Qingqing said in surprise: "Daddy made this for me to play with?"
Zhang Yang assembled the parts, and the wrench in his hand was tightening the internal nuts. "Well, after this thing has worked well, I'll give it to you to play with."
"OK."
She began to look at the car expectantly, and then asked: "Aunt Dongyang told my daughter that I am different from them."
Zhang Yang took off his gloves, did some more detailed assembly, and said, "What's different? They have one mouth, one eye, and two ears."
Xiao Qingqing smiled and said, "Well, my daughter is just like them."
Xiao Qingqing walked to her mother again, "Mom, is there any difference between Aunt Xiaowu and the others?"
Li Yue drank tea leisurely. Every summer is the most leisurely day in Lishan. When she is free, she can calm down and read a book. This is her favorite time.
Listening to her daughter's words, she explained: "You don't have to be the same as others, 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 the Tang Dynasty."
"What's the difference between dad and others?"
"So many different ways of saying it."
Li Yue talked about what happened with Zhang Yang in the past. Xiao Qingqing listened carefully and heard how her father had deceived Uncle Wei Wang before. She always held her stomach and laughed for a long time.
As the mother of a child, Li Yue knew very well that even if she had a son, Zhang Yang had actually taught her daughter since she was a child.
In fact, this child has a very high cognitive level and can learn everything very quickly.
If we really want to say they are different, it is their understanding of the world that is different.
In Xiao Qingqing's eyes, people outside are stupid, everyone in the world is unconscious, aristocratic families are bastards, and the emperor is not a good person.
After a few days of peaceful life, I didn't have so many things to worry about in the DPRK these days, and my life was very comfortable.
Zhang Yang hoped that it would be best not to bother Lishan with the affairs of the court.
These days, I concentrate on making train parts and polish them carefully in the workshop.
The aunt came pushing a cart and said, "Marquis, the craftsmen made this. Let's see if it's right."
Zhang Yang took the Lishan ruler, measured it carefully, and said for a long time: "It's not a big problem. I'll just go get these parts from now on. They're very heavy."
Aunt Wang waved her hand and said, "Auntie used to go out to fight, so she has enough strength to stay out of the way."
Zhang Yang frowned and watched his aunt leave, pushing the car's parts into the workshop.
One morning half a month later.
There were some noises outside the house, "Sister, it's moving!"
Xiao An's words came.
Xiao Qingqing looked outside the door and saw that the little train started to move. It was running along the rails and spinning in circles.
A wisp of smoke came from the nose of the train.
Zhang Yang took off his gloves and let out a sigh of satisfaction, "Well, it's finally done. This half month was not in vain."
The little train kept clicking, and all the bears in the family gathered around it. Xiong Sansheng’s little bear was very lively.
However, it is easy for these newly born cubs to mistake bears. Sometimes they will follow Bear 2, or Bear 5 and Bear 6.
They have almost grown in size, so my aunt often admits that they are wrong.
The train stopped after more than ten laps. Zhang Yang used water to cool down the small train and wait for it to dry before use.
"Dad, why don't you move?"
Zhang Yang put the small train into the cart, "This should be given to the factory and let them study it themselves."
Then he put the rails into the bamboo basket, carried it on his back, and pulled the car all the way down the mountain with both hands.
Xiao Qingqing and Xin'an were reluctant to leave, and they were still following behind.
Li Tai stood with several craftsmen and were discussing the generator.
Seeing his brother-in-law coming, he stepped forward and said, "Brother-in-law, has it been built?"
Zhang Yang put down the cart and explained: "This is the train model I made. The specific principles are similar to those on the drawings, but you have to change the position when you cast it."
Let the two children lay the rails. Zhang Yang placed the small train on the rails. First, he put a burning log into the hole above the front of the car, and then filled the rear of the car with water.
Then put pulverized coal on top of the locomotive, and after burning a cup of tea, the little train started to move.
Zhang Yang took the drawing and explained to Li Tai, "In fact, the structure is very simple, and the copper tube does not need to be bent too much."
Li Tai couldn't help but nodded and asked the guard beside him to take a note and write down these words.
The train moved smoothly, the movement was not that loud, and there was some black smoke coming out of the locomotive.
"In the past, the main problem with our trains was that they were not light enough. I used to think that the interior of the train was too complicated. After repeated improvements and simplifications, it is much better now."
Zhang Yang explained: "So I simplified it a bit, leaving only the combustion chamber and increasing the space of the water tank."
Li Tai frowned and said: "In this case, it needs to be more precise."
"Well, it will be more troublesome."
"Just leave it to me." Li Tai accepted the drawings and was more confident this time.
"How is your electromagnetic research?" Zhang Yang glanced at the large cylinder on the side, "Is it generating 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 attracts iron."
"Brother-in-law, do you think this electromagnetism is also related to the attraction of magnets?"
Zhang Yang frowned and said, "It's possible."
Every creation in Lishan takes time, including springs and steam engines. Now Li Tai wants to generate electricity, which is another difficult task.
With the mentality of giving it a try, Lishan cannot stand still and must always explore forward.
Li Tai whispered: "The Western Expeditionary Army said that they found a very powerful magnet in the Western Regions and had people dig it out."
"A powerful magnet?"
"Well, during the Western Expedition, a group of soldiers and horses got lost in the desert." Li Tai paced back and forth and explained: "They had a compass, but the direction of the compass was wrong. Later, they brought it back through the local people from the Western Regions. This
The troops and horses were punished for delaying the military flight, and then returned to Chang'an to be interrogated by the officers and soldiers of the Wei Mansion."
"After questioning and asking them how they delayed the military plane, they explained that the compass was broken. This matter was spread to the army. Later, they understood the reason. It turns out that there is a Cishan in the Western Regions. Whenever swordsmen approach, they will be sucked to the mountain wall.
superior."
Zhang Yang frowned and thought.
Li Tai added: "Since it can be so far apart, it is probably a very powerful magnet. I have sent a message to ask people from the Anxi Protectorate to help quarry the stone. Perhaps a stronger magnet can stimulate the electricity."
.”
To see the current, you need a certain voltage, which is not easy.
Zhang Yang patted his shoulder and said, "I hope so."
Li Tai looked at the gloomy sky, "Brother-in-law, is that electricity really like the thunder and lightning in the sky?"
"Yes, it will glow, but there won't be such a big movement."
Li Tai smiled and said: "If Lishan can really create this, then Lishan will really be an immortal mountain, and the people of Lishan will be immortals."
Xiao Qingqing nodded heavily, "Then we are immortals."
The power of knowledge is powerful, so powerful that it can reach heaven and sea, and can change the world.
Now Lishan is still in its most basic stage, leaving everything to Li Tai to arrange, and Zhang Yang returned to the mountain.
The factory in Lishan is very busy, with endless work to do every day.
When Lishan seemed to have spent all his wealth and distributed his property, no one knew what else Lishan was busy with.
Screws and nuts were manufactured one by one. These screws and nuts are the key to the next stage of Lishan's casting.
Recently, there has been a group of students from Lishan who have returned home after learning skills. These students are all descendants of Guanzhong.
Xiaohui and Xiaowu were talking with the magistrates of each county.
The two girls looked serious, and their tone of conversation was different from ordinary people.
"Lishan will accept 1,500 students this year. The number of places in each county is still the same. Thirty students are above the age of thirteen and below fifteen."
Several county magistrates are each thinking about the population in their own counties.
Xiaohui added: "If there are those who are rich and dissatisfied with the recruitment, the quotas will be decentralized. Of course, since each county has cooperated with Lishan, we can let you exchange quotas with each other, but these quotas cannot be sold out. If there is anyone who sells the quotas for profit,
Once discovered, we will not cooperate again.”
"How could it be?" The magistrate of Jing County wiped the sweat from his forehead, "Lishan has given us so many conveniences, how could we cut off our own retreat?"
"Yes, yes."
Listening to the discussion of several county magistrates, Xiao Wu added: "In line with the principle of fairness and justice, the treatment of students from each county after admission is the same as that of students recruited from outside. This is based on our limited operating conditions."
Xiaohui took over the words and added: "Lishan has never cared about the origin and origin of students. Lishan plans to select a site and build a large academy outside. The land in Lishan is limited. If the excess land in each county can be used
To build an academy, you can write documents and give them to Lishan."
Seeing that these county magistrates were about to speak again, Xiao Wu interrupted: "The next technical institute should be able to recruit three thousand students, occupy an area of about two thousand acres, and build high-rise buildings."
After hearing this request, several county magistrates fell silent again. Two thousand acres of land was not a small amount, let alone the need to build high-rise buildings.
The county magistrate of Weinan County was confused and asked: "Who needs 2,000 acres of land to build a house? Is this to build a city?"
The magistrate of Sanyuan County whispered: "This is just building a city."
The remaining county magistrates also looked solemn, building a city? A city dedicated to studying and learning technology?
This sounds incredible.
Originally, each of them was just a small county. It would be good if they could manage it well. But if we still need to build another city, how much manpower and material resources would be needed?
The county magistrates immediately lost interest and stopped talking. Everyone reached a consensus that if a city was built on the edge of their own county, and whether it would benefit their own county, trouble would probably ensue in the future.
Come.
If you put in people's efforts, you may not be able to make a profit in the end.
Looking at the two girls in front of them, they didn't say what benefits they would give to the counties.
Xiao Wu and Xiao Hui bowed to the county magistrates and left.
Twelve county magistrates from twelve counties walked out of the temporary official residence outside Lishan Village.
"Have you informed the governor of Jingzhao about this matter?"
The speaker was the magistrate of Fuping County, a man who never had any opinions.
