Zhang Yang looked at Huaqing Pond and looked up at the sky again, "This pool should be washed with water." ”

Rolling up his sleeves, ready to block the water source of the hot spring pool upstream, Zhang Yang glanced sideways, "Huh? Why are you still here, Princess? ”

"County marquis, these five thousand are really ......"

Zhang Yang walked into the firewood room, which is both a firewood house and a bear's den, and every time the wood is tidied up, it will be tossed into a mess by the bears at home.

And put these pieces of wood neatly one by one, like a thickened wall, and it is very pleasant to look at densely.

After cleaning the bear's den again, when Zhang Yang came out with a sandbag, the prince was no longer here.

After blocking the upstream inlet, Zhang Yang opened the downstream water valve and released the water from the entire Huaqing Pond, and the water flowed down the ditch from the bottom of the mountain to the back, along the waterway and diverted all over the mountainside.

In the past, the water of Huaqing Pond was very turbid, but now it is so clear that Zhang Yang can't stand the silt in the pool.

The bottom of Huaqing Pond is paved with stone bricks, which is easy to clean.

When the water was finished, Zhang Yang carried a broom and swept at the bottom of the pool.

Li Zhi, Gao Yang, Qinghe and other children also came back, and they also went down to the bottom of the pool together to clean up together.

The appearance of an adult sweeping the floor with a group of children is very comfortable.

Li Yue hummed a ballad and packed up the clothes that had been dried, which was a ballad that the children had sung before.

The atmosphere on Lishan Mountain is relaxed and freehand, and Xiao Qingqing and Xiao Zizi are playing a game of throwing sandbags.

It wasn't until it was dark that the pool was halfway cleaned.

After the dinner in the evening, the children were writing the homework assigned today, simple math and essay interpretation in the library cabinet.

The daughter-in-law and Xiaohui have to prepare accounts for the next year's production.

It was quiet in the library room, and there was an oil lamp on the desk of each of the younger siblings.

When they finished their homework, they dispersed in twos and threes.

Zhang Yang sat cross-legged, holding the table with one hand, looking at the book in his hand, this is a book compiled by Li Chunfeng recently, he combined the astrology with personnel, and put forward a very interesting outline, which is the call of the door.

Most astrologers in history became more and more mysterious the more they learned, and Zhang Yang felt that with Li Chunfeng's arithmetic realm and understanding of celestial phenomena and stars, he could not go in the direction of those evil words.

Most astrologers in history have been known for being flattering, and Li Chunfeng's attainments should not be that way.

And Yuan Tiangang is now moving forward in the calculation of latitude and longitude, and he wants to redefine the appearance of the world.

However, Li Yue has mastered all this, and from the day she can measure the latitude and longitude, her only doubt is the true face of the world.

This direction is the same as Yuan Tiangang's thinking, and the puzzle that fascinated the ancients was what the heavens were like and what the world was like.

In this era when technology cannot be explored, people rely on their own cognition to persist in exploration.

The saying that the world is a round ball has spread among many nobles, and more and more people have begun to debate it.

Zhang Yang thought that more related theories would appear in the future, but now it is just a sign that there may be an unprecedented debate in the future.

When his daughter-in-law came with a plate of dumplings, Zhang Yang came back to his senses, looked up and glanced at the library, and the children didn't know when they had left.

The couple sat opposite each other, a plate of dumplings was put down, and she handed over a pair of chopsticks.

"Husband, what kind of book are you reading?" Li Yue said curiously.

"Daoist Li Chunfeng wants to compile an astrology book."

"Really?" Li Yue picked up a dumpling and put it in his mouth to eat, sighing: "Hmm! The dumpling wrappers made by my aunt are very tough and delicious. ”

Zhang Yang dipped some vinegar and put one in his mouth, "I want to correct Li Chunfeng's thoughts." ”

"How can it be corrected?"

"Astrology can tell the climate change, or the change of the years, why all Taoist priests who have a little bit of Taoism should associate the stars with good fortune and misfortune."

Li Yue said in a low voice: "People are all in reverence and awe of the starry sky, and not everyone thinks like Fujun, the starry sky is the starry sky, and it has no symbolic meaning. ”

When talking to a daughter-in-law, you will always be explained from some other perspective.

She is also right, preconceived that the stars have no symbolic meaning and are difficult to convince.

The ancients also paid attention to seeking truth from facts, and first of all, they had to provide evidence, and the changes in the stars had nothing to do with the man-made situation.

After the couple finished eating a plate of dumplings, Li Yue made another cup of tea, "I heard my wife say that when the teacher gave my father a hexagram, it was my father who launched a mutiny in Xuanwumen, but my wife said that the teacher never looked at books such as hexagrams, and the teacher didn't understand these at all, and it was completely forced by the situation at that time." ”

"But the situation is compelling, it is exactly what the father and emperor need, the emperors of all dynasties are ordered by heaven, even if the husband gives evidence, no one will believe it."

Li Yue's expression was indifferent, he picked up the incomplete astrological scroll compiled by Li Chunfeng, and said in a low voice: "Yi Si Zhan? Well, a very interesting book name, the husband believes that things are man-made, but the sons of heaven in all dynasties are the destiny of heaven. ”

This is a cognitive conflict.

Zhang Yang smiled: "Thank you for reminding your daughter-in-law." ”

Li Yue put away the empty disk and said: "This astrological phenomenon is not the other astrological phenomenon, and predicting the climate is essentially a very complex science, right?" ”

Zhang Yang didn't answer, just looked at her.

Her smile is very good-looking, especially when she is confident, after several years of precipitation, Zhang Yang feels that she has reached a new level of understanding of things.

She sat up lazily, "I'll wash the dishes and chopsticks." ”

Sitting alone in the library cabinet, there are many books in this library that are the results of the daughter-in-law's reading.

Zhang Yang picked up Li Chunfeng's book again and looked at it, and when the night wind blew, the lights shook a little.

"It's really tiring to read like this." Zhang Yang got up and blew out the oil lamp here and walked out of the library pavilion.

The night in Lishan is very quiet, so silent that only the sound of the wind can be heard.

Without the distress of trivial matters in the DPRK and China, Li Shimin slept until dawn.

The next day, Zhang Yang finished breakfast, and there was a bowl of soup and medicine in front of him.

Because of the firearms, Li Shimin also came to Lishan early, he knew Zhang Yang's living habits, he was a person who would get up early no matter how late he went to bed.

Lishan has not changed much as always, last year, Zhang Yang built a workshop, and there are no plans to build it again this year.

"You want to drink a decoction too?"

Zhang Yang nodded and said: "This is a decoction to nourish the spirits, the first two months my son was very noisy, and he didn't sleep well every night, so I don't sleep well now, and now that the child is stable, I have to start recuperating my spirits." ”

Seeing that Li Shimin was already sitting in front of him, Zhang Yang held up the soup bowl and said, "Your Majesty, do you want to drink some too?" ”

"It's fine."

Evenly mixed half a bowl of the decoction in the bowl, and the two of them drank the decoction and drank it in one go.

The bitter decoction entered his mouth, Li Shimin frowned and looked at him, this kid was a little worried about the country and the people like this.

Zhang Yang put down the medicine bowl in his hand, "This decoction medicine has a bowl in the morning and evening, prepared by Doctor Sun, if Your Majesty doesn't sleep well, you can also try it." ”

Li Shimin didn't sleep well before, but since the victory in Yinshan, he has been much better, even in his dreams, he dared to scold Li Jiancheng, and since then his waist has been straight.

With the decoction in his mouth, Zhang Yang rinsed his mouth with tea again, and said curiously: "The weather has been cold in the past two days, and most of this spring cold will last until April, and please pay more attention to the cold and warmth." ”

"How do you know?"

"In addition to being busy with farming, Taifu Temple should also pay attention to the celestial phenomena, when it rains, and what the climate is like in early spring this year, all of which we have to pay attention to, and we are about to develop occupational diseases."

"What is an occupational disease?"

"It's nothing, Your Majesty doesn't have to care."

Li Shimin said suspiciously: "You kid is young, why are you sick?" ”

Zhang Yang said melancholy: "Seeing that I am about to turn over thirty, I will be healthy when I am over thirty." ”

"Thirty is young and strong."

"Your Majesty laughed."

"I didn't laugh, I made a vow when I was thirty years old, and I fought with the Turks in this life! If Li Jing had been defeated, I would have fought with Jieli! ”

The hero doesn't say that he was brave back then, the emperor likes to say that he was brave back then, and no one stopped him.

Seeing that Zhang Yang had set up the tea bowl again, this kid looked calm and relaxed, how to look at it and make people unhappy.

Li Shimin patted the case and said: "A cannon costs 5,000? ”

Zhang Yang nodded, "Your Majesty, this is a very affordable price." ”

Early in the morning, the spirit was good, Li Shimin was angry, his spirit was even better, he breathed out of his nostrils, and said in a deep voice: "You just robbed my palace." ”

"Okay, then Your Majesty will let me rob it?"

"Heh, with your Lishan alone, you can't even attack Chang'an City, and you still want to rob it?"

As soon as the words fell, Li Shimin looked at him with a thoughtful look, as if he really planned to attack Chang'an City.

As long as this kid dares to attack Chang'an City, he will die.

Li Shimin looked at the look of the kid in front of him with great interest, and immediately thought about the way to kill this person, and even had many tricks.

"If Your Majesty thinks that the price is not suitable, those powder cartridges I gave Your Majesty can also be used, and it is more than enough to scare those messengers."

"I want artillery! I need a firearm that can blow through the walls! ”

As soon as the emperor slapped the table, he wanted the best.

Zhang Yang held a small clay teapot in one hand, frowned, and said, "Then Your Majesty wants to give money." ”

"Five thousand guan is too expensive, do you negotiate with you because of who I am?"

"Artillery can also blast through the city walls, especially when the other side is defending the city, the city gate is nothing, and it is useless under one shot."

"Nothing?"

"Well, artillery can break through all battle formations at a distance of a hundred paces, and if it is an anti-aircraft fire, it can ruin the war of the other side without much effort even before the two armies engage in battle."

Hearing this, Li Shimin's expression became more and more solemn, and in the blink of an eye, Zhang Yang had more ways to die.

"Your Majesty, how much iron ore did we use in Lishan for a spring? It all required silver, and we used 2,000 pieces of silver to make the springs. ”

"Just for the springs?"

"Hmm."

"How do I remember that you saved the rest of the hematite?"

"Well, the development of technology consumes resources very much, and the remaining hematite will soon be insufficient, so after that, Lishan bought a lot of iron ore from the court, and said that the steam engine cast by His Royal Highness the King of Wei is just to buy refined copper and iron ore, and it costs more than 5,000 guan to buy refined copper in the court, and 7,000 guan of iron, counting manpower and various consumption, it will cost 20,000 guan in three years, and now Your Majesty still thinks this is a small amount of money?"

Li Shimin was silent, he really couldn't understand how Zhang Yang's account was calculated, and how Lishan's money was spent.

I always felt that Lishan didn't spend so much money, and I felt that Zhang Yang's words seemed to be right.

If you really want to give him 5,000 yuan, Li Shimin is reluctant in every way.

Zhang Yang continued: "Your Majesty can also pay part of the silver money first, and the rest of the silver money can be replaced with resources. ”

Seeing that there was room for maneuvering in the silver coin, Li Shimin immediately nodded, "You say, whatever you need, I can give it to you." ”

"Ten stones of hematite, a discount of 100 yuan, the specific discount is according to the quality of iron ore, Your Majesty don't think about shoddy, our blacksmith skills in Lishan are top-notch, and the level of understanding of iron ore is also very high."

Li Shimin gritted his teeth, "Ten stones of hematite, only a hundred times?" Do you want 500 stone of iron ore? ”

Zhang Yang said with a smile: "If Your Majesty can't get five hundred stones of hematite, you can also give money directly." ”

Iron ore of 500 stone is the concept, which can build a hill.

Li Shimin's breathing was heavy, "Don't you think the price is very inappropriate?" ”

"Since Your Majesty feels sorry for the iron mine, then pay the silver."

"Then do I want to pay it?"

"Then give the money, that's right! This is only the price of one artillery, and His Majesty can buy a few more. ”

Knowing that this kid must be taking advantage of the fire to rob, Li Shimin couldn't let him get his wish, and he didn't want him to succeed.

Finally, this time the bargaining was very unpleasant, the deal was not negotiated, and Li Shimin waved his sleeves and left.

This is how to negotiate the price with the emperor, the emperor always feels that the whole world is his, as long as he likes something, he must obediently take it.

Zhang Yang didn't want to get used to the emperor's problem, and the emperor had to pay for a vacation in Lishan.

Even if you live here, the emperor doesn't want to pay, so he can let the emperor's son, His Royal Highness King Wei, pay it, and just deduct the money from the account.

When the emperor left, Zhang Yang walked to the kitchen, and when he opened the lid, he was greeted by the smell of beef.

The sauce beef is now ripe, so I'm waiting to be eaten after it cools.

Zhang Yang picked up a slice and put it in his mouth to taste, the sauce beef made of yak did not taste good.

At least it's beef, adding some flavor to your home.

Except for one of the five yaks in Lishan that day and distributed them to the villagers in the village, the rest of the cattle became sauce beef, and the beef bones had been boiling in the pot for two days and two nights.

When you open the lid, there is a smell of cattle on Lishan.

Today's meal, there is still beef bone soup, Zhang Yang fished out a cow bone and threw it to a few bears at home.

As for the big tubular bones, I give it to my younger siblings who are growing up.

Yak is very important to the Tibetan people, and yak dung is a good building material and a good fuel for the Tibetans.

The Tibetans also do not slaughter yaks easily.
