Knowledge must have a reason, not to mention whether Newton's theory of gravity requires a story about apples.
Knowledge can never come from nothing.
Zhang Yang returned to the mountain and looked at the volume of Qi Min Yao Shu in his hand. Most of the records in it were rumors from the countryside or inquiries from the public, and most of them were based on records.
You see, when people write about knowledge, they are well-founded.
So how can Lishan’s knowledge be justified?
Zhang Yang sighed: "We still have to rely on Taoist Yuan."
Li Yue has been having more and more difficulty moving recently. She said slowly: "When will this little guy be born?"
The aunt joked: "Your Highness, there is no need to rush this kind of thing."
Looking at Xiao Wu and Xiao Hui's busy figures, Li Yue held her waist and said again: "Husband, we haven't played chess for a long time."
"Why do you suddenly want to play chess?"
"Lately, I always feel that my thoughts are empty and my heart is empty."
Zhang Yang brought the chessboard and played chess again.
The chess game is spread out, and the fighting begins as the chess pieces are pushed again and again on the chessboard.
The situation was incomprehensible for a while, Zhang Yang frowned and said: "I finally have an opponent in the chess game."
Li Yue was still happy when she heard her husband's approval.
The two sides fought back and forth.
I don't know if it was because of her pregnancy that her thoughts became more agile.
The game was very anxious. Zhang Yang took a sip of tea and watched as her last pawn was eaten by her horse.
Looking at the chessboard, the only movable ones are the bishop and the rook.
After a few more moves, Che was also surrounded and killed by her.
Zhang Yang said discouraged: "I lost."
Li Yue whispered: "My husband's chess skills have deteriorated."
"Well, maybe."
"Now my husband is just Minister Zuocheng. He is very close to me, but he is less interested in planning and calculating."
Zhang Yang nodded and said: "It would be good to have less strategy and more awe-inspiring righteousness."
Li Yue packed up the chessboard, stood up and walked back to the library with satisfaction. Xiao Qingqing handed in her homework to Xiaohui.
Xiao Wu whispered: "Teacher, is Master worried about something lately?"
"Did you see it too?"
"Well, Master always sits alone lately?"
Li Yue sat down carefully, holding her waist, and said with a smile: "He just wants too much."
"Master, are you still worried?"
"Yeah." Li Yue said softly.
Xiao Wu added: "I thought that after the family fell, the master would have no rivals."
Li Yue smiled and said: "My husband's opponent..."
After thinking about it, Li Yue frowned and said: "If we really want to talk about opponents, in fact, his only opponent has always been his father, that's the only one."
"Why did the teacher say this? I don't understand."
Li Yue explained in a low voice: "Aristocratic family or Tubo, these are just the conditions for the battle and game between your master and the emperor."
Xiao Wu said in a low voice: "Disciple understands, no matter what the aristocratic family or Tubo is, the one who is praised is still the emperor, and the one who benefits is Lishan."
Li Yue sighed: "After so many years, it's been ten years. Aren't they tired?"
Xiaohui replied: "I'm probably tired."
Li Yue smiled and nodded.
At night, everything is quiet.
Even in summer, Lishan is still a bit cool at night.
The hot spring water flows down the stone wall and into the Huaqing Pool. The sound of the water is white noise, which is very comfortable to listen to.
Zhang Yang was sitting in his study, reading the memorials from the imperial court. The Hanhai Protectorate in Mobei was completed, and many coal mines were discovered in the surrounding area.
Li Shimin has always attached great importance to developing production, reducing taxes and labor for farmers, and rebuilding the coastal areas of Jiaozhou, Fuzhou, and Mingzhou.
It is planned to restore the coastal area to the vitality of the pre-Sui period.
This memorial was proposed by Zhang Xingcheng of Zhongshu Province.
Rebuilding local areas and cooperating with the center should not be like this. To be precise, it is wrong to spend so much money.
The construction of a central place is like dressing a person, first making a person bright and beautiful, and then making a place prosperous.
To read and be literate, to become an official, faith should come first.
Building bridges and building roads also puts demand first.
Rather than a random word from the emperor, there are no specific measures and systems to throw out a hundred thousand guan.
There is nothing that can be done about it. Once the emperor is rich and has confidence in his heart, he will naturally build it.
"Who asked Pei Xingjian to bring so much gold to the emperor?"
Listening to her husband's words, Li Yue also frowned and said: "Lishan should be allowed to take charge of Chaozhong's money bag, alas."
Zhang Yang picked up another memorial and looked at its contents carefully.
As Luoyang became increasingly prosperous, the imperial court also noticed the impact of commercial activities on the country.
As for the governance of the Hexi Corridor, the DPRK and China learned from the governance experience. Li Shimin planned to re-enact a law for merchants. This law would change the previous theme of light punishment.
"My work as Minister Zuocheng has been completed again."
Li Yue nodded and said: "My husband is Zuo Cheng, but he can only read these memorials every day."
Zhang Yang added: "It's not that your Majesty doesn't allow me to give advice."
"Sigh, I don't know what my father thinks."
Zhang Yang remembered Master Cui Ren's words again and whispered: "That old man from a noble family, no! It should be said that he is an old man."
"From his point of view, the world will not change. Every emperor is the same."
Li Yue frowned and said: "Will the noble family rise again after it falls?"
Zhang Yang whispered: "Even if the aristocratic family falls, there will be more people like the aristocratic family who will surface."
Li Yue remained silent.
"Why! Why are they staring at the last bits of ordinary people's lives and clinging to them so hard?"
Every time he thought of this, Zhang Yang had endless disgust and contempt in his eyes.
Outside the study, Xiao Qingqing was supervising his younger brother's writing, and he could vaguely hear the conversation between his parents.
Xin Xin'an whispered: "Sister, what are your parents talking about?"
Xiao Qingqing sat upright and closed her eyes and said, "Our parents are different from other people's parents."
"How different."
Xiao Qingqing slowly opened her eyes, looked out at the night and said, "Didn't you listen to what they said? Our parents are the sun and moon of the Tang Dynasty."
She lowered her voice and said, "My parents are immortals who have come to benefit the Tang Dynasty."
This chapter is not over yet, please click on the next page to continue reading! Xiao An scratched her head in pain, "My parents are not in the sky either."
"That's right, it's not in heaven, but it's better in heaven."
Seeing that his brother's handwriting was wrong again, Xiao Qingqing said angrily: "How many times have I taught you, but this is not how the word is written."
Xiao Xing'an said unconvinced: "The shapes of the two characters are almost the same, why do we need to learn these two characters?"
"This is our Lishan calligraphy. My parents only let us learn it."
"Sister," Xin Xin'an begged, "please lend your brother some of your talents."
Xiao Qingqing said disgustedly: "If I can lend it to you, will I still use this place to write with you?"
"..."
"Rewrite!"
Xiao Xin'an sniffed aggrievedly and pouted: "Oh."
On this day, a story spread in Chang'an City, and the people of the Tang Dynasty had a new story.
Anyanyan was the richest man in Sifangguan. He squandered a staggering amount of money. He also often gave money to some people from the Western Regions who returned home.
When those people from the Western Regions encountered difficulties living in Chang'an City, he would also give them money.
Anyan Yan is the most charitable person in Chang'an City.
At this moment, Anyanyan was preaching to Songtsen Gampo in the Sifang Pavilion: "There is a fruit tree in Mount Li, called the apple tree."
"One day, Taoist Yuan was sitting with the Marquis of Lishan County discussing Taoism, and suddenly he was hit on the head by an apple."
Songtsen Gampo was silent while eating licorice. After hearing this story, he felt that this new story was very strange.
An Yanyan continued: "Later, Taoist priest Yuan sat down with the Marquis of Lishan County to discuss Taoism and came to a conclusion called universal gravity. Everything on the earth is affected by gravity."
Songtsen Gampo laughed and said: "This story is really bizarre."
"Yes, the stories are all bizarre."
"You...are you really not the mouthpiece arranged by the Marquis of Lishan County in Chang'an City?"
Anyanyan smiled confidently, "The county prince doesn't need a mouthpiece, Zanpu has a look around."
Songtsen Gampo glanced at it and said, "What's wrong?"
"The people here are the mouthpieces of the Marquis of Lishan County. No need to say it down below, they can praise the Marquis of Lishan County as immortals."
Among them, there was originally the theory of longitude and latitude, and the earth has a curvature. This bizarre story added a piece of the puzzle to the theory of longitude and latitude.
The earth is not flat, and people can walk on it because of the force of gravity.
This knowledge will be written in Lishan Mountain, such as the scientific article produced by His Highness the King of Jin.
Of course, as soon as this story came out, many people talked about it.
Does the earth have gravity?
Of course, the story is just a story. Lishan has an attitude of letting people discuss it and is still busy with construction and development.
Li Shimin was pacing back and forth in the Ganlu Hall. The story was very simple, with only a few sentences.
The emperor adjusted his glasses and said with a smile: "What do the people say?"
His Majesty's appearance with glasses made people uncomfortable. Li Junxian said in a low voice: "Back to Your Majesty, there has been a lot of discussion in the public. Some people say that this is evil talk to deceive the public. It's surprising that many people agree with Li."
Mountain."
"Do you also think this is nonsense?"
Li Junxian quickly lowered his head, not daring to answer.
"Lishan's knowledge has always been like this. Zhang Yang views everything in the world differently from ordinary people."
Li Shimin put his hands behind his back and raised his head again and said: "He couldn't find any allusion to explain it, so he made up such a story. In fact, Zhang Yang lived in Lishan for a long time and never saw Yuan Tiangang again. He just came up with such a story just to complete it.
His Lishan doctrine.”
Hearing this, Li Junxian looked suddenly and said: "Your Majesty has learned from this."
This is of course a clear warning. His Majesty was able to judge Zhang Yang's intention and purpose just by relying on this story.
Outside Lishan Village, road construction is still under way. The laying of railway tracks is very laborious and the progress is very slow.
In Lishan Village, Li Tai checked the steam engine again, took a deep breath, and said with expectation: "Brother-in-law, this time it will definitely succeed."
After this improvement, the originally complex internal structure of the steam locomotive was simplified a lot.
Zhang Yang clasped his hands and said melancholy: "The brakes haven't been installed yet, so it's not good to drive out like this."
"It doesn't matter, thank God if it can move."
Li Tai didn't have high expectations this time. Braking is not necessary at the moment. It would be nice to be able to move.
The furnace in the steam locomotive had been burning for a while, until a whistle sounded and the car finally started to move.
The chimney above it spewed black smoke.
At first its speed was very slow, but after the children ran along for a while, the speed of the car became faster and faster until the children could no longer keep up.
Seeing the car driving out of the village, Li Tai looked excited and said, "Brother-in-law, we succeeded again."
Zhang Yang patted his shoulder and whispered: "There's something wrong with the whistle. Let's take a look again."
Li Tai got on his horse and chased after him with his bodyguard.
Yan Liben still stopped where he was, he was still in a daze.
Zhang Yang cupped his hands and said, "Thank you Master Yan for your hard work."
Yan Liben came to his senses, stroked his beard and said, "I'm just improving on Lishan's original creation."
"We at Lishan Academic School have always focused on theory as well as practice."
"Well, I have read a lot of Lishan's books, and I have learned a lot. Steam, heat, force area, and the principle of leverage are all very interesting knowledge."
"I'm glad that Master Yan has gained something."
Yan Liben lowered his face and said: "Since I am working for you in Lishan to pay off your debt, I should wait until the railway construction is completed before leaving."
"I believe Master Yan will keep his promise."
It started from Lishan Mountain, speeding up faster and faster, heading all the way towards Chang'an.
Pedestrians on the official road stopped one after another, looking at this big guy blowing out black smoke and being speechless for a long time.
They saw a monster they had never seen before in their lives, and its screams were so loud that they echoed throughout the countryside.
Li Tai rode beside the car and shouted to the people in the car: "How is the stove?"
There were two people in the car, one was adding coal, the other was holding the pull bolt and pulling it, and the whistle sounded again.
When the stove is burning, it needs to be constantly vented to release some pressure. Every time the pull bolt is pulled, some of the pressure in the stove will be released, otherwise it will explode.
Listening to the "thump" sound of the steam locomotive, Li Tai closed his eyes and listened for a while again. This time he heard some noise inside the steam engine.
He shouted: "Quickly jump out of the car! The load is not enough."
After saying that, the two people in the car looked aside in panic. There was a piece of mud not far away, and they abandoned the car and jumped.
Not caring about the steam locomotive, Li Tai stepped forward and asked, "How are you doing?"
The guard came forward to confirm that both of them had scratches on their bodies. After checking again, they found, "Nothing serious."
Li Tai breathed a sigh of relief, looked at the route, and marked the distance, "I walked ten miles this time."
"His Royal Highness King Wei, that car..."
Looking into the distance, I saw that the steam locomotive had traveled very far, and when it was approaching the boundary of Chang'an City, it finally exploded.
The explosion was so loud that it alarmed the officers and soldiers in Chang'an City.
Li Tai led people to clean up the place, and a group of guards put the broken parts on the cart.
They were in a low mood, "The car that His Highness King Wei spent more than two months building was just destroyed."
Not long after, the officers and soldiers came, and it was Pei Xingjian who brought the officers and soldiers to inquire.
"I heard that there was a monster running towards Chang'an City in Lishan, so I came to take a look." He saluted and said, "I will be the governor of Jingzhao Prefecture."
Li Tai looked at Pei Xingjian and said with a smile: "I have disturbed the Chang'an order."
"Your Highness, King Wei, what is this?"
"A kind of vehicle that can transport goods. I pulled it out and tried it today."
The front of the car was in pieces, but the rear was still intact. Pei Xingjian walked around and asked people to draw pictures according to the model.
