Li Shimin looked at the rubble on the ground, "At the beginning, this was also a palace, and it used to be ten years ago when I came here with my father to spend the winter. ”

"So Your Majesty is here to remember? But this is already my home. Zhang Yang shook off the snow on the hat, and the snow kept falling intermittently, which was also annoying.

Li Shimin walked from the aisle in the middle of the square Huaqing Pool, which is divided into four pools, and if you put the hot spring water down, the water level will not pass the steps here, and it is also very beautiful from a distance.

Successive emperors have enjoyed it, and even if it is rebuilt, it can still remind people of the gorgeous palaces of the past.

The new home that has just been completed, this is a prototype, Zhang Yang stood under the eaves to avoid the snow, watching the emperor walk to his side step by step.

"Your arrangements are very good, so that I can go to the palace to hold a banquet with confidence."

"This is what Yue'er advocates, the Emperor Taishang is an elder, if His Majesty's conditions are not good, I can support the elderly on my behalf."

Li Shimin said in a deep voice: "I am not a merciless person. ”

Zhang Yang nodded, Li Shimin did not slaughter heroes like other emperors, it can be regarded as his righteousness, although there is not much righteousness, the military power of the generals who fought back then has been handed over, and even Li Jing locked himself at home and has never seen guests.

"What kind of person Your Majesty is, in fact, you don't need Your Majesty to prove it yourself, I think it would be better to prove it with facts."

"How?"

"For example, pay me back the money that mortgaged Qujiangchi first."

Li Shimin closed his eyes and took a deep breath, "Does this have anything to do with my personality?" ”

Zhang Yang nodded, "It has something to do with it, I know that Your Majesty's conditions are difficult, but it's okay, I'm not in a hurry." ”

There is also a stone table at the door of the house, and there is a short stone pillar like a stool on the side, Li Shimin simply sat down, "I have received the news, white sugar has appeared in Luoyang, and many children of the family in Luoyang have been talking about it recently. ”

"Your Majesty, rest assured, everything is going well."

"I don't care about your tricks, I hope you can expand the paper workshop, you have a paper mill, and you can print more books to fight against the family, I think this is the real way to fight the family."

"Not to mention whether it is technically possible to achieve greater production efficiency, it seems to me that it is not necessary to blindly increase costs to increase output, and besides, it is not only the books that the family relies on to win over readers, but also the power of the family."

"Books alone can have a certain impact on the family, but it can't cause much harm, I don't read much, but I have understood a truth since I was a child, there is a difference between going up the mountain to fight the bad and going up the mountain to eliminate evil, and different methods need to be used."

Thinking about it carefully, the emperor's eyes were also staring at this matter, and Zhang Yang looked up at the sky with his hands in his hands, and the people who thought he was melancholy could be more or less optimistic for so many years.

Now it's good, Lishan's production has reached a bottleneck, and it needs to be improved through technology.

Li Shimin, the father-in-law, didn't want to help Lishan, and urged Lishan to lay eggs for him all day long, hoping that Lishan would come up with results to boost his confidence as a heavenly khan.

I don't care about these alone, this emperor is still playing Infernal Affairs with me behind his back.

Luoyang's affairs just had some signs, and he knew about it so quickly, and he told me.

Just say directly, my eyeliner is all over the world, don't be ignorant.

"The family can entrench in one side, can't be two words money and power, the summary is resources, they can control more people when they master the distribution of local resources, if I am Your Majesty, I will send a team of soldiers and horses to investigate everywhere, but all corrupt people should be taken down, so that the world will be clean."

Seeing that the emperor looked at himself in disbelief, he even glared.

The new home is facing south, and the northwest wind can't blow, Zhang Yang took out the wooden cup tied to his waist, opened the lid and took a sip, "What does Your Majesty look at me?" Isn't dealing with the family something His Majesty has always wanted to do? ”

"The auxiliary machine often tells me to be gentle with the family, to slowly cut off their power, and they can replace them in the future, when Jinyang raised troops and received the support of many scholars, if they do it again, they can also pull up another army and horses."

Zhang Yang said again: "Your Majesty is too worried, if Your Majesty can unite thousands of people, that is the greatest source of strength, and those families are just flies and dogs, and there is nothing to be afraid of." ”

"Those who have achieved great things in the past generations have asked for the lives of the people, only the people are the foundation of the society, not who the scholars support, and please read more books and read more, the truth is in the book."

"How many years have you been studying?" Li Shimin said coldly.

"Although I have not been reading for a long time, I have read no less books than Your Majesty, and if Your Majesty feels that he is preaching, then he will take these words as a deaf ear."

】

Zhang Yang stood under the eaves and saw that he was still sitting in the wind and snow, "Your Majesty doesn't need to pretend to be deep, be careful of the wind chill, come to stand under the eaves, this time to see if the walls and roof of the new home will have problems in the cold winter." ”

"Now that everything is fine, Your Majesty will please, and the minister will go down the mountain first."

"Wait."

Zhang Yang looked at him puzzled, "Your Majesty, is there anything else?" ”

After keeping his mouth shut, Li Shimin sighed: "You have a different view from the auxiliary machine. ”

Saluting towards Chang'an City, Zhang Yang said again: "Zhao Guogong has the world in his heart, it is for the Tang Dynasty, and the ministers are also for the prosperity of the Tang Dynasty. ”

Thinking of the political views of the eldest grandson Wuji, and listening to Zhang Yang's current words, Li Shimin is a lot more relieved, Zhang Yang's biggest reliance is his youth, even if he is young, can he fight the eldest grandson Wuji?

If there is a dispute between the eldest grandson Wuji and Zhang Yang in the court, the future court must be very exciting.

"You are very young and you have a vision, but things often do not go as you wish, and it is better for young people to be down-to-earth."

"Thank you Your Majesty for admonishing me, I will go on step by step."

Saluting again, Zhang Yang said in a low voice: "The minister will retire first." ”

Li Shimin nodded, "I'll take a look here." ”

"Then Your Majesty will continue to miss it."

Zhang Yang turned around and was about to leave, when he bumped into Li Junxian again, "General Li is by His Majesty's side as always." ”

Li Junxian looked ahead, his face expressionless, "I should be dedicated to my duties." ”

The most heroes in Datang are heroes, and the most important thing is to kill talents, which is the most beautiful scenery in Datang, and the folk customs are simple.

The young man's heart is contrary to the style of yearning for heroes and heroes, and now His Royal Highness the King of Wei is dancing with a horse lance under the mountain, and his little face is flushed and it is very difficult.

Li Chengqian was playing sandbags on the side, and he was at ease.

Zhang Yang stepped forward, "His Royal Highness the Crown Prince is still insisting on punching sandbags?" ”

Li Chengqian punched the sandbag, "All year round, be persistent." ”

Since he insisted on exercising, Li Chengqian's complexion has improved a lot, that is, the prince's body is thin, but he is too well raised and lacks exercise, and he is just in his early twenties, so he should exercise more.

The little fat on the other side dropped the horse lance and wiped his sweat.

"Is this king practicing for half an hour to fight the prince for an hour." Li Tai asked the guards beside him loudly.

For the guards, it is definitely not good to offend the King of Wei, but it is not good to offend the crown prince.

This is a proposition, the guard thought for a moment and said: "If His Royal Highness King Wei can persist every day, he can also lose weight if he wants to." ”

Li Chengqian took out two volumes of books and said, "I heard from Xiao Wu that you and Yue'er have been studying astrology recently, so I asked people to send these two books to the palace. ”

Zhang Yang took this roll of bamboo slips, the bamboo slips looked very old, and the mottled traces and almost pulped traces told its long time.

Open this book, and take a closer look at the two words that come into your eyes are "Lingxian"

Then I opened another book, "The Theory of Reckoning"

"This is a two-volume strange book written by Zhang Heng in the Han Dynasty, and it has been shelved when it looks remote, although it is a manuscript, there are not many that can survive in its entirety, I learned that you and Yue'er specialize in astrology, I think it may be helpful to you."

Zhang Yang hurriedly put away the two volumes, "Thank you, prince." ”

Li Chengqian relaxed his wrist, "If you need anything in the future, just talk to Lone, Lone will definitely help you." ”

After getting married to the prince, it is needless to say much about the friendship with the prince.

"Is there a way to crack my brother-in-law's bronze mirror?"

Zhang Yang said wistfully: "There are still some difficulties. ”

Li Tai bowed his head and said, "Don't worry. ”

The prince showed goodwill, and Li Tai naturally did not dare to slack off.

Zhang Yang walked to his residence and saw that Li Tai was still following, "His Royal Highness King Wei, there has been a lot of trouble in our village recently. ”

Li Tai looked around, "It's cold, how can you make trouble?" ”

"I mean, His Royal Highness King Wei can pay more attention to whether there are any strange people in our village recently, such as near a few of our factories."

"That's going to be arranged."

"His Royal Highness the King of Wei walks slowly."

There was a large group of children in the residence, and I couldn't go there.

Zhang Yang walked to his daughter-in-law's account room, which is an important place in the village, and no one usually sets foot here.

He walked into the account room with the scroll and sat in the place where his daughter-in-law usually sits, and there were three accounts on the table, one was the village's flowing water, and the other was the village's outflow account.

Zhang Yang opened the third volume, and this volume of accounts said that since it was for his daily expenses, thirty articles a day were written on it.

She even had a total, counting the price of meat and vegetables in the East Market of Chang'an City, and calculated all the flowers.

"The husband kept a total of 1,600 yuan."

Marveling at the daughter-in-law's ability to make accounts, in fact, her account is not right, and she can save a lot of money by bargaining, and the uncles and aunts who are familiar with the market can also save a lot of money.

opened the scroll given by the prince, and if you want to say that Zhang Heng has to go back to the time when Emperor Guangwu Liu Xiu ascended the throne.

This strange man in history, the geodynamic instrument cast by later generations is also amazed when they see it.

The book Lingxian is also the only book that Zhang Heng can leave behind.

The book given by the prince is only one of them, and Zhang Heng compares the sky to an egg and the earth to an egg yolk.

And then it's very jerky to read later.

It can be vaguely understood that it means that the sun, moon and stars move between heaven and earth.

Zhang Yang put away the two books again and walked out of the account room again.

Yu Yi stood at the door and bowed slightly, "I know that the county marquis is in the account room, so I don't dare to disturb." ”

Zhang Yang glanced at her, then nodded and left.

When he came to his residence, Xiao Wu was giving a lecture to the children.

Zhang Yang handed the two books to his daughter-in-law, "This is from the prince." ”

Li Yue took the bamboo slip and opened it and looked at it, "Nothing?" ”

Zhang Yang nodded, "Zhang Heng was also a master of mathematics back then. ”

"I know that Zhang Heng wanted to measure the magnanimity of heaven and earth back then, so he had this book."

These two volumes are fragments, and they are recorded in a few words.

In terms of mathematics, Zhang Heng almost explored, and his progressive fractional method was also taken out by later generations to talk about it.

Then there is the algorithm of pi, Zhang Heng is ahead of the West for I don't know how many years, and he has already calculated the 3.16 of pi.

Xiao Wu is giving a lecture to the children, which is the simplest vertical form in mathematics, starting from the very basics.

After Xiao Wu finished speaking, Zhang Yang took the children to do a small experiment, floating half of the candle on the water, and then using a cup to turn the candle upside down.

Under the children's amazed gaze, the water in the basin decreases at a rate visible to the naked eye.

Li Zhi looked curiously, "Where did all this water go?" ”

Zhang Yang pointed to the upside-down wooden cup, "His Royal Highness King Jin opened this cup to try?" ”

Li Zhi reached out to take the upside-down wooden cup, and was a little struggling for a while.

It wasn't until I picked up the whole wooden cup that I found that the candle in the wooden cup had been extinguished, and the water that had been sucked into the wooden cup had come out.

Li Lizhi looked surprised, "How did the water go to the cup?" Will the water burrow into it on its own? ”

Looking at the children's curious eyes, Zhang Yang smiled: "Do you remember the test of water from the well?" ”

A group of children nodded stunned.

Empress Changsun stood at the door and watched this scene, a group of children gathered around a basin of water and sat around Zhang Yang.

Li Yue stepped forward and whispered, "Queen Mother, my husband is teaching my younger brothers and sisters. ”

Empress Eldest Sun said in a low voice: "Your father is going back to the palace. ”

"How many more days?"

"It's Chinese New Year's Eve soon, the clan and the family have also arrived, and there are many things to deal with, so I can't stay for long."

Li Yue took some more sauced beef from home, "The queen mother will take these beef away, and my father can also take it back to the palace to eat." ”

The queen did not refuse, and instructed: "Seeing that your and Zhang Yang's child is about to be born, you will have to take care of Lishan's family business more in the future, there are many things to take care of as a housewife, don't always study by yourself." ”

"The words of the queen mother must be remembered by the daughter."

Zhang Yang gave the children homework and asked them to explain the principle of this little experiment.

Knowledge should be consolidated from time to time, and the principle of water coming out of the well was a change in air pressure, maybe they just thought it was fun, and now they have forgotten it.

Zhang Yang said: "As long as you can explain the cause of this phenomenon, I will make a cake for each of you." ”

As soon as they heard that it was a cake, the children showed a yearning expression, knowledge can be forgotten, and they will never forget the cake they ate once last year.

Gao Yang swallowed his saliva uncontrollably.

The children dispersed in a hurry, the eldest grandson queen left with them, and the little bear finally dared to come out of the storehouse, and it walked to Li Yue's feet aggrievedly, as if seeking comfort.
