There must be a reason for learning, not to mention whether Newton's gravitational pull requires a story about the apple.

Learning must not be groundless.

Zhang Yang returned to the mountain and looked at the volume of Qi Min's Essentials in his hand, most of which were recorded in rural rumors, or inquiries from the streets, and most of them were based on records.

You see, when people write about learning, they are justified and well-founded.

So how can Lishan's knowledge be justified?

Zhang Yang sighed: "I still have to rely on Yuan Daochang." ”

Li Yue's movement has become more and more inconvenient recently, and she said slowly: "When was this little guy born?" ”

The aunt quipped: "Your Royal Highness Princess, this matter is not urgent. ”

Looking at Xiao Wu and Xiao Hui's busy figures, Li Yue held his waist and said, "Husband, we haven't played chess for a long time." ”

"Why do you suddenly want to play chess?"

"Lately, I always feel empty in my mind and empty in my heart."

Zhang Yang brought the chessboard and played chess.

The chess game spreads out, and the fight on the chessboard begins as the chess pieces are pushed again and again.

The situation was inextricable for a while, Zhang Yang frowned and said, "I finally have an opponent in the chess game." ”

Hearing her husband's approval, Li Yue was still happy in her heart.

The two sides fought back and forth.

I don't know if it's because of pregnancy, but her mind is more agile.

The game was very anxious, Zhang Yang took a sip of tea, and watched his last pawn also be eaten by her horse.

Looking at the chessboard again, the only things that can be moved are the elephant and the car.

After a few more rounds, the car was also surrounded and killed by her.

Zhang Yang said discouragedly: "I lost. ”

Li Yue said in a low voice: "It's Fujun's chess skills that have regressed. ”

"Well, probably."

"Now the husband is only Zuo Cheng of Shangshu Province, and he is very close to the phase, but he is less calculating and calculating."

Zhang Yang bowed his head and said: "It's good to have less strategy and more Haoran righteousness." ”

Li Yue packed up the chessboard, got up and walked back to the library with satisfaction, and Xiao Qingqing handed over her homework to Xiaohui.

Xiao Wu said in a low voice: "Teacher, Master has something on his mind lately?" ”

"You see that, too?"

"Well, lately, Master has always been sitting alone?"

Li Yue sat down cautiously with his waist and said with a smile: "He, he just wants too much." ”

"Is Master still troubled?"

"Hmm." Li Yue said softly.

Xiao Wu said again: "I thought that after the family fell, the master would have no opponents." ”

Li Yue smiled: "Husband's opponent......"

After thinking about it, Li Yue frowned and said: "If you really want to talk about opponents, in fact, his opponent has always been only his father, so this is the only one." ”

"Why does the teacher say this, the disciple doesn't understand."

Li Yue explained in a low voice: "The family or the Tibetans, these are just the conditions for the struggle and game between your master and the emperor. ”

Xiao Wu said in a low voice: "The disciple understands, no matter how the family is or what Tubo is, it is the emperor who is praised, and it is Lishan who is benefited. ”

Li Yue sighed: "So many years have passed, it's been ten years, aren't they tired?" ”

Xiaohui replied: "Most of them are tired. ”

Li Yue smiled and nodded.

At night, everything is quiet.

Even in summer, Lishan is still a little cool at night.

The hot spring water goes down the stone wall and enters the Huaqing Pond, and the sound of the water is white noise, which is very comfortable to listen to.

Zhang Yang was sitting in the study, flipping through the recitals of the court, the Hanhai Protectorate in Mobei was completed, and many coal mines were found around.

Li Shimin has always attached importance to the development of production, reduced the peasants' taxes and labor, and rebuilt the coastal areas of Jiaozhou, Fuzhou, and Mingzhou.

It is intended to restore the coastal area to the vitality of the pre-Sui period.

This piece was proposed by Zhang Xingcheng of Zhongshu Province.

It shouldn't be like this to rebuild the place and cooperate with the center, and it is not right to spend so much money to be precise.

The building of a place in the center is like dressing people, first making a person glamorous, and then making a place flourish.

Reading and literacy, becoming an official, and faith first.

Building bridges and building roads is also demand-first.

Instead of the emperor's casual words, there are no specific measures and systems to throw out 100,000 yuan.

This is also something that can't be helped, the emperor has money and confidence in his heart, so he naturally wants to build.

"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 the money bags in the court, alas." ”

Zhang Yang picked up another piece of music and looked at its contents carefully.

As Luoyang became more prosperous, the DPRK and China also noticed the impact of business practices on social welfare.

With the governance of the Hexi Corridor, and drawing on the experience of governance, Li Shimin planned to reformulate a law for merchants, which would change the previous theme of light punishment.

"My work as a scholar is done again."

Li Yue nodded and said, "The husband is dignified, but he can only watch these pieces every day. ”

Zhang Yang said again: "It's not that Your Majesty won't let me admonish. ”

"Alas, I don't know what my father thinks."

Zhang Yang remembered Cui Renshi's words again, and said in a low voice: "That old man of the family, no! It should be said that he is old. ”

"In his view, the way of the world will not change, every emperor is the same."

Li Yue frowned and said, "Will the family rise again after it falls?" ”

Zhang Yang said in a low voice: "Even if the family falls, there will be more people like the family who will surface." ”

Li Yue was silent.

"Why! Why do these people have to stare at the last bit of life of ordinary people, and just hold on to it? ”

Every time he thought of this, Zhang Yang's eyes were filled with endless disgust and disdain.

Outside the study, Xiao Qingqing was supervising his younger brother's writing, and he could vaguely hear the conversation between his father and mother here.

Careful An whispered: "Sister, what is Daddy talking about?" ”

Xiao Qingqing sat upright and closed his eyes and said, "Our father and mother are different from other people's parents. ”

"How different."

Xiao Qingqing slowly opened his eyes, looked at the night outside and said, "Didn't you listen to them?" Our father and mother are the sun and moon of Datang. ”

She lowered her voice and said, "Daddy is an immortal, and she came to grace the Tang Dynasty." ”

Careful Ann scratched her head in pain, "Daddy is not in the sky." ”

"Yes, it's not in heaven, it's better in heaven."

Seeing that his younger brother's handwriting was written incorrectly, Xiao Qingqing said angrily: "How many times have I taught you, this character is not written like this." ”

Careful An was unconvinced: "The shape of the two characters is almost the same, why do we want to learn these two characters." ”

"This is the word of Lishan, and my father and mother only let us learn it."

"Sister." Careful Ann begged, "Lend some of your talents to my brother." ”

Xiao Qingqing said disgustedly: "If I can borrow you, will my sister still use here to accompany you to write?" ”

“……”

"Rewrite!"

Careful Ann sniffed aggrievedly and pouted, "Oh." ”

On this day, a story circulated in Chang'an City, and the Tang people had a new story.

An Yanyan is the richest person in the Sifang Pavilion, he squanders a staggering amount of money, and he often gives some people from the Western Regions who have returned home.

Those people from the Western Regions who had difficulties living in Chang'an City would also give money.

An Yanyan is the most benevolent person in Chang'an City.

At this moment, in the Sifang Pavilion, An Yanyan preached to Songtsen Gampo: "There is a fruit tree in Lishan called the apple tree. ”

"One day, Yuan Daochang sat down with the Hou of Lishan County to discuss, and suddenly he was hit on the head by an apple."

Songtsen Gampo was silent eating licorice, and when he heard this story, he felt that this new story was very strange.

An Yanyan continued: "Later, Yuan Daochang sat down with Lishan County and discussed the Tao, and came to a conclusion, called gravity, everything on the earth is affected by gravity. ”

Songtsen Gampo laughed: "This story is really bizarre. ”

"yes, the stories are bizarre."

"You're a man...... Isn't it really the mouthpiece arranged by the Marquis of Lishan County in Chang'an City? ”

An Yanyan smiled confidently, "The county marquis doesn't need a mouthpiece, Zampu take a look." ”

Songtsen Gampo glanced at it and said, "What's the matter?" ”

"The people here are all the mouthpieces of the Marquis of Lishan County, and there is no need to say that they can praise the Marquis of Lishan County as immortals."

There is a theory of latitude and longitude, and the earth has arcs, and this bizarre story complements a piece of the puzzle of latitude and longitude.

The earth is not flat, and people can walk on the earth because of gravity.

These knowledge will be written in Lishan, such as the science article taken out by His Royal Highness the King of Jin back then.

Of course, as soon as this story came out, many people talked about it.

Is the earth gravitational?

Of course, stories are just stories, and Lishan has put on an attitude of letting people talk about it, and is still busy building and developing.

Li Shimin paced back and forth in the Ganlu Palace, the story was very simple, so simple that it was only three or two sentences.

The emperor lifted his glasses and said with a smile: "What do you say?" ”

His Majesty's appearance with glasses makes people look very unaccustomed to it, Li Junxian said in a low voice: "Back to Your Majesty, there is a lot of discussion in the market, some people say that this is a fallacy to confuse the public, but it is strange that there are still many people who approve of Lishan." ”

"Do you think that's a lie?"

Li Junxian hurriedly lowered his head, not daring to answer.

"Lishan's knowledge has always been like this, Zhang Yang looks at everything in the world differently from ordinary people."

Li Shimin put his hands behind his back, raised his head and said: "He couldn't find an allusion to discuss, so he made up such a story, in fact, Zhang Yang has lived in Lishan for a long time and has never seen Yuan Tiangang again, but he came up with such a story just to improve his Lishan theory." ”

Hearing this, Li Junxian suddenly said, "Your Majesty Mingjian." ”

Of course, this is a clear understanding, Your Majesty can judge Zhang Yang's intentions and purposes just by this story.

Outside the village of Lishan, roads are still being built, and the laying of railroad 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 looked forward to it: "Brother-in-law, this time it will definitely be successful." ”

After this improvement, the steam locomotive, which originally had a complex internal structure, was simplified a lot.

Zhang Yang waved his hands and said wistfully: "The brakes haven't been installed yet, so it's not good to drive out like this." ”

"It doesn't matter, thank goodness it can move."

This time, Li Tai didn't have too high expectations, and the brakes are not necessary at present, so it's good to be able to move.

The furnace inside the steam locomotive had been boiling for a while, until a whistle sounded and the car finally moved.

The chimney above it spewed black smoke.

At first it was very slow, and the children followed it for a while, and the car got faster and faster until the children could not keep up.

Seeing the car drive out of the village, Li Tai's expression was excited, "Brother-in-law, we have succeeded again." ”

Zhang Yang patted him on the shoulder and said in a low voice: "The whistle is a little wrong, let's take a look." ”

Li Tai turned over and got on his horse, and chased after him with his guards.

Yan Liben was still standing still, he was still in a trance.

Zhang Yang arched his hand and said, "Master Yan has worked hard. ”

Yan Liben came back to his senses, stroked his beard and said, "The old man is just improving on the original creation of Lishan. ”

"Our Lishan academic school has always paid attention to theory and practice."

"Well, the old man has read a lot of books on Lishan, and he has gained a lot, steam, heat, force area, and lever principle are all very interesting knowledge."

"Master Yan can gain something, I am glad below."

Yan Liben lowered his face and said: "Since you are doing things to pay off your debts in Lishan, the old man should wait for the railway construction to be completed before leaving." ”

"I believe that Master Yan will keep his promise."

It started from Lishan, and the speed became faster and faster, all the way to Chang'an.

Pedestrians on the official road stopped one after another, looking at this big guy spitting black smoke and speechless for a long time.

They saw monsters that they had never seen before, and their cries were loud and resounding throughout the four fields.

Lee Tae rode beside the car and said to the people in the car, "How is the stove?" ”

There were two people in the car, one was adding coal, and the other was holding the bolt and pulling, and the whistle sounded again.

When the stove is burning, you need to keep venting to release some pressure, and every time you pull the bolt, you can release some of the pressure of the stove, otherwise it will explode.

Listening to the "click" sound of the steam locomotive, Li Tai closed his eyes and listened for a while, and this time he heard some noise in the steam engine.

He shouted, "Jump out of the car!" The load is not enough. ”

After that, the two people in the car looked to the side in a panic, and there was a muddy field not far away, so they abandoned the car and jumped over.

Unable to take care of the steam locomotive, Li Tai stepped forward and asked, "How are the people?" ”

The guard stepped forward to confirm that both of them had abrasions on their bodies, and checked again, "It's okay." ”

Li Tai breathed a sigh of relief, looked at the road, and did a good job of marking and recording the distance, "This time I walked ten miles." ”

"His Royal Highness the King of Wei, the car ......"

Looking into the distance, the steam locomotive had already run far away, and when it was close to the boundary of Chang'an City, it finally exploded.

The explosion was loud, alarming the officers and soldiers in Chang'an City.

Li Tai led someone to clean up the place, and a group of guards put the broken parts on the cart.

They were in a low mood, "His Royal Highness King Wei bothered to build a car for more than two months, and it was destroyed like this. ”

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 is a monster in Lishan running towards Chang'an City, so I came to take a look." He saluted and said, "Xiaguan Jingzhao Mansion Yin." ”

Li Tai looked at Pei Xingjian and smiled: "It's time to disturb Chang'an." ”

"His Royal Highness King Wei, what is this?"

"A kind of car that can transport goods, I pulled it out today and tried it."

The front of the car was broken, the rear of the car was still intact, Pei Xingjian walked around, and let people draw it as it was. (End of chapter)
