Zhenguan Han-in-law

Chapter 258 Don't Know
Chapter 254

Wei Hao said he wanted to make a bet with Li Shimin, Li Shimin heard it, and immediately nodded in agreement.

"Okay, as long as you find these problems in the book, I read 100 books, if not, hehe, don't mention my reading in the future!" Wei Hao said very proudly standing there.

"You wait with me, you said it yourself!" Li Shimin pointed to Wei Hao and said happily.

"Success, then tell me, which book has been written?" Wei Hao nodded, looked at Li Shimin and asked.

As soon as Li Shimin heard it, he stood there thinking about it, but found that there was really nothing.

"You have read so many books. I don't know how many books are piled up in your study. Have you read them all?" Wei Hao saw him thinking there, and immediately asked Li Shimin proudly.

"Well, the books I read are too complicated, just wait, I will definitely find them out for you!" Li Shimin said to Wei Hao.

"I'm waiting, hmph, if we still run education, no one will know that the Ministry of Industry is actually the most important, and craftsmen are also very important. Good craftsmen, craftsmen who are capable of inventing new things, can bring huge benefits to the entire Tang Dynasty. benefit.

Don't talk about other things, just talk about paper, father, tell me, how much wealth it brings to Datang, let's not talk about other benefits brought, just talk about wealth!And the porcelain I made, Father, tell me, is it a huge wealth, and there is also the salt, right?Why no one pays attention to it?
On the contrary, those who talk about benevolence, righteousness and morality, and secretly corrupt the country's money, are on the contrary. They have read a lot of books, but besides standing on the heads of the people, what wealth have they created for the people?Also, just talk about building roads, let me just say a simple thing, can bridges be built on the Yellow River? "Wei Hao continued to ask Li Shimin as he spoke.

"How is it possible, the Yellow River is so wide, how to build a bridge?" Li Shimin stared at Wei Hao and asked, thinking about what Wei Hao said just now, it is true that these inventions can bring great benefits to Datang. wealth.

"Of course it can be repaired, but those officials don't know how to repair it at all. They think that these researches are weird skills and useless!" Wei Hao said very positively.

"There is also gunpowder. Wang Jun had a hard time before. There is no funds. If he is given enough funds, let him study it carefully. The gunpowder he produced will bring great benefits to Datang, although I made the gunpowder. It came out, but Wang Jun can get it out sooner or later, but no one pays attention to him!" Wei Hao continued to ask Li Shimin.

"Well, what you mean is that we should pay attention to those craftsmen!" Li Shimin thought about it and asked Wei Hao.

"Of course we must pay attention to craftsmen. Those who say that craftsmen are inferior, that is pedantic, are fools! Let's just talk about those projectile vehicles, and those that project stones are still improving. What are the benefits of improvement? If you go to your own area, you can still hit them. This can determine the outcome of a battle, greatly reduce our army's casualties, and improve our army's combat odds. But what about those officials? Who cares about them? You go Take a look at the Ministry of Industry, the entire Ministry of Industry does not have a heater, and the officials of the entire Ministry of Industry are poor, isn’t this ironic? They brought so many benefits to Datang, but in return they were neglected by the court. Still the poorest!" Wei Hao continued to complain there.

Li Shimin heard it, and walked ahead with his hands behind his back, thinking about it.

"Craftsman, the court is the most important person, even more important than those scholars. Those scholars only say that after successful study, they will become officials and manage the people, but they can't bring wealth, but craftsmen can. Father , I really feel unworthy for those craftsmen, so you said that you want me to manage the library and school, I have never had much interest in it myself, but I also know, father, you need more children from poor families, Go there, minister, otherwise, I don't care about such things!" Wei Hao continued.

"Well, what you said, I will think about it carefully, but you really need some snacks in the library and school!" Li Shimin said to Wei Hao.

Wei Hao nodded, and then the two continued walking.

"Does the artisan you mentioned just now have anything to do with what you said about why it thunders? Those artisans understand?" Li Shimin thought of this and asked.

"They don't understand, but they can slowly study and figure it out. If they don't have enough living security, who would study this? It's useless if you look at it, but this is a basic thing, just like mathematics, Zu Chongzhi Did you know? Proposed pi!" Wei Hao looked at Li Shimin and asked.

"Zu Chongzhi, I really don't know this very well! Which dynasty are you from?" Li Shimin asked.

Zu Chongzhi was from the Southern and Northern Dynasties, and it is only a hundred years ago. The pi he studied is not popularized at all. He even said that he still does not know in which family the thing he wrote is still kept.

"In the Northern and Southern Dynasties, they studied how to calculate the area of ​​a circle. This is very important, because if the pi is determined, then many mathematical algorithms can be determined. For example, if I want to build a circular bridge pier, I need to use How many bricks do I need to build a round patio, how much earth do I need to dig out, and so on, this is basic research, it seems that it has no practical effect, but it is very useful, but unfortunately no one understands it!" Wei Hao was a little bit Said with emotion.

Datang’s mathematics is still very low-level. Wei Hao deliberately read mathematics books and found that it is not as good as elementary school mathematics. In this way, how can Datang’s technology develop? Without the support of mathematics, natural science cannot develop at all. .

Seeing Wei Hao's emotion, Li Shimin immediately asked, "You understand?"

"Of course I understand, father-in-law, it's not me bragging with you. All the people in the entire Tang Dynasty may not be as good at arithmetic as I am. If I ask a problem, no one in the entire Tang Dynasty will be able to solve it!" Wei Hao was immediately proud Said.

How could Li Shimin trust him? He even asked a question that no one could solve?
"Okay, tell me, I've also studied arithmetic, tell me!" Li Shimin immediately said to Wei Hao dissatisfied.

"Okay, let's say a cone. The diameter of the bottom circle is 30 inches, and the height is 60 inches. What is the volume of this cone!" Wei Hao looked at Li Shimin and asked.

Li Shimin looked at Wei Hao dumbfounded.

"Father, what do you think I am doing, you count!" Wei Hao said to Li Shimin.

"Well, how do I calculate it here? I will calculate it after I go to the Ganlu Hall. Anyway, you remember, you must manage the school well, and you are not allowed to fool around, and you are not allowed to play cards in the school. It's shameless. Look What is the state of the criminal prison now? Every time you go there, you just play cards. How many ministers come to impeach you? Go to the Minister of State and ask how many impeachment memorials you have!" Li Shimin stared at Wei Hao and reprimanded him.

Wei Hao heard it, curled his lips, and said nothing.

Then Li Shimin continued to walk forward, and Wei Hao followed.

After walking for about half an hour, Li Shimin returned to Ganlu Hall, while Wei Hao went to Da'an Palace to see the old man. When he arrived at Da'an Palace, he naturally needed to play mahjong.

"You boy, it's okay to provoke those ministers to do something, no one dares to provoke them like this!" Li Yuan sat there, playing cards and said to Wei Hao.

"I'm used to their problems. They say they want to beat me, but I can bear them? Let me tell you, it was Uncle Cheng who hugged me. Otherwise, I beat them in the court. There is no way. Several people hugged me, and I couldn't walk through!" Wei Hao said depressingly, feeling that he still suffered a loss in his heart, and suffered a big loss for not being able to hit them.

"Stop fighting, if you are still fighting in the hall, you are not afraid that your father-in-law will punish you?" Li Yuan continued to say to Wei Hao.

"Hey, don't mention him, what a fool, I'm a captain, and I don't have any salary this year. Hey, can the old man resign as a captain?" Wei Hao thought of this question, looked at Li Yuan and asked.

"If you are a son-in-law, a son-in-law must be the captain of the son-in-law. Don't you want to be a son-in-law?" Li Yuan said with a glare at Wei Hao.

"Forget it!" Wei Hao dismissed the idea when he heard it, the son-in-law still has to do it, otherwise, how can he marry a beauty!
On the side of Ganlu Hall, Li Shimin summoned Yuan Tiangang, Li Chunfeng, and those from Qin Tianjian, and threw Wei Hao's problem to them and asked them to solve it.

"Thunderstorms and snowfall are weather changes. Why do these things happen? It seems, um, how should I put it, this is God's intention!" Yuan Tiangang said.

He can figure out when it will rain or not, but why it rains and why it thunders, he really doesn't know!
"Then why did you see the lightning first, and then hear the thunder?" Li Shimin continued to ask them, completely ignoring what those people asked.

"Your Majesty, why do you want to know this?" Yuan Tiangang couldn't help but looked at Li Shimin and asked, you are an emperor, why do you want to know this?
"It's not that I want to know, it's Wei Hao who asked these questions, aren't these questions written in the book?" Li Shimin looked at them and asked.

"This, Shuchen is ignorant and ignorant, I really haven't seen it!" Yuan Tiangang shook his head and said, thinking in his heart why Duke Xia wanted to know these things, he was really full and had nothing to do.

"In addition, here is a question, which of you can solve it, a circle, 30 inches in diameter, 60 inches in height, what is the volume of this cone!" Li Shimin looked at them and asked.

"Ah?" Those people all looked at Li Shimin in shock.

"You are all from Qin Tianjian, and you are also very good at arithmetic. I hope you can solve this problem. Wei Hao posed this question, and he concluded that you can't solve it!" Li Shimin said while sitting there.

"Your Majesty, don't worry, we will definitely answer it for you!" Li Chunfeng said immediately, clasping his hands.

And Yuan Tiangang looked at Li Chunfeng depressedly, why did you promise to do nothing, can you figure it out?

"Well, I want the answer tomorrow!" Li Shimin nodded and said, and then asked them: "Is there really no answer to those questions in the book?"

"Return to Your Majesty, there may be, but we haven't seen it!" Yuan Tiangang said immediately, clasping his hands.

"Oh, that's fine, I'll ask those ministers the day after tomorrow, the day after tomorrow is just a grand court!" Li Shimin nodded when he heard it, and said a little disappointed.

Soon, Yuan Tiangang and the others went back to calculate this problem, but everyone didn't know where to start. The cone, the volume, is terrible!

"Why do you agree to nothing? You can figure it out now!" Yuan Tiangang said to Li Chunfeng.

"Isn't this very simple? Calculate the volume, isn't it difficult?" Li Chunfeng looked at Yuan Tiangang in confusion and asked.

"Then forget it!" Yuan Tiangang waved his hand and said, he didn't know it, but Li Chunfeng was dumbfounded, he didn't know it, he knew it because of Yuan Tiangang.

"This...you don't know it either?" Li Chunfeng looked at those people in Qin Tianjian and asked, regretting that he agreed too soon.

Those people all shook their heads, no!

"No, this, is it difficult? Or, let's figure it out together? If we can't figure it out, it will be shameful!" Li Chunfeng looked at Yuan Tiangang and the others and asked.

Yuan Tiangang was very helpless, this is what His Majesty wanted, if he couldn't figure it out, it would be very embarrassing. Then, they discussed the volume of this cone all night.

"Is Wei Hao free? Why do you want to count this? I think, let's go to the math school and ask those gentlemen, maybe they will!"

The next morning, they didn't sleep all night, and they still didn't figure it out.

"Well, let's go, ask others!" Yuan Tiangang also conceded defeat, couldn't figure it out, so he had to ask everyone for help.

Soon, they went to the Mathematical Academy under the Imperial College, where there were some people who were good at arithmetic. After they asked the question, the entire Mathematical Academy was calculating this, but no one would.

In the evening, they still can’t, there is no way, they can only go to tell Li Shimin, Li Shimin wants them to come up with the answer today, but it is already evening, if they don’t give it, then it is against the decree, will they also need to go Say it.

"What, didn't figure it out? Is it difficult? It's such a simple question?" Li Shimin looked at him in shock when he heard Yuan Tiangang said that he didn't figure it out.

"Yes, Your Majesty, I haven't figured it out, not only my ministers have not figured it out, but even the people in the Mathematical Academy have not figured it out!" Yuan Tiangang said helplessly. The topic seemed simple, but he really couldn't figure it out.

"Is it so difficult?" Li Shimin still found it hard to understand, how could he not figure out such a simple question.

"Your Majesty, otherwise, His Majesty will ask those ministers tomorrow to see if they will?" Yuan Tiangang looked at Li Shimin and asked tentatively.

"Well, okay, I'm going to ask tomorrow!" Li Shimin nodded, he really needs to understand this matter, otherwise, Wei Hao doesn't know what kind of complacency he will become, and he just can't see him complacent.

The next morning, after Wei Hao finished his martial arts practice, he went to have breakfast. After breakfast, Wei Hao still wanted to go back to sleep.

"You son of a bitch, why haven't you set off yet? You're going to court today!" Wei Furong came to Wei Hao's side, looked at Wei Hao and shouted anxiously.

Wei Hao was stunned for a moment, and went to court!

"My God, I forgot!" Wei Hao quickly stood up and ran outside. Now it was already daylight and the palace gates were open!
"Hurry up, you bastard!" Wei Furong was in a hurry behind, but now is not the time to scold Wei Hao.

Soon, Wei Hao rode to Chengtian Gate, got off his horse, and ran in quickly. Now those ministers were already in the court, discussing those things. When Wei Hao arrived at Ganlu Hall, Cheng Chusi on duty .

"Stop, I'm late, I can't go in, I can't go in until His Majesty summons you!" Cheng Chusi stopped Wei Hao and said.

Wei Hao stared at Cheng Chusi.

"Don't look at me like that, I dare not let you in, this is the rule!" Cheng Chusi rolled his eyes and said.

"Oh, okay, I won't go in, I'll just wait outside!" Wei Hao didn't make things difficult for him when he heard this, and went to sit on the promenade next to him.

"I said you kid too, can you be late for the court?" Cheng Chusi followed behind Wei Hao and said.

"Forgot, really, forgot to go up!" Wei Hao looked at Cheng Chusi sincerely and said, and then the two sat on the corridor, waiting to go down.

After about half an hour, the main matters were discussed and the ministers were ready to go down. At this moment, Li Shimin said, "I have a few questions for you. Well, Wei Shenyong, where is Wei Shenyong?"

Li Shimin shouted.

"Huh?" Li Jing also turned his head to look left and right. He knew that Wei Hao had come out, but why didn't he see him this morning.

"Return to Your Majesty, it seems that you haven't come!" Cheng Yaojin immediately stood up and cupped his hands and said.

"Have you asked for leave?" Li Shimin looked at Wang De and asked.

"Return to Your Majesty, no, there is no registration here!" Wang De immediately opened the notebook, this was sent from the city gate, if you want to ask for leave, the city gate will have a registration, and before going to court, it will be sent to the Ganlu Hall .

"How dare you not come to court?" Li Shimin pretended to be very angry and said in his heart, no wonder it was so quiet today, it turned out that this kid didn't come.

"Your Majesty, why don't you go outside and have a look, maybe something has delayed you, come here now!" Wang De immediately asked Li Shimin.

Li Shimin nodded, and then Li Shimin asked them questions, such as why it rained, why there was thunder, and so on. The ministers who asked were all looking at me and looking at you, thinking about who was wrong, and went to investigate these problems, and then Li Shimin continued, talking about the volume of the cone, those ministers listened, but no one spoke.

"Which of you will answer these questions?" After Li Shimin finished speaking, he looked at the ministers and asked.

"Your Majesty, these questions should be answered by the people from Qin Tianjian?" Fang Xuanling stood up and said with cupped hands.

"They won't!" Li Shimin said a little depressed.

"Ah?" Those ministers were shocked when they heard this, how could the people from Qin Tianjian not know?
"Besides, you are all scholars, tell me, are there no answers to these questions in the books?" Li Shimin continued to ask the ministers.

But at this moment, just as Wang De went outside, he saw Wei Hao and Cheng Chusi chatting there.
