Hongwu Daming: Why hasn't my son rebelled?

Chapter 109 The Mathematics Book of His Royal Highness King Liao
The math problem posted by Zhu Qi in Yingtianfu is a quadratic equation system written in Arabic numerals and mathematical symbols.

It can be said to be quite simple.

After all, Zhu Qi did not intend to summon Western scholars to conduct research and exploration of advanced mathematics. He mainly wanted to popularize mathematics subjects.

At present, mathematics is the most convenient and popular. If you talk about chemistry, physics, biology, etc., it requires a lot of preparatory work.

For example, chemistry requires the support of materials science and physics.

And it also involves a lot of calculations, such as mechanics in physics.

All in all, it is very unrealistic to want to fully blossom in the natural sciences. Zhu Qi remembers the science things he learned when he was in school, because of the relationship with the benefits of time travel, he remembers them clearly.

However, it is too difficult to carry out basic education in Daming to develop these subjects in an all-round way, and the possibility is not high.

Where does the large amount of education funding come from?Daming is still fighting Bei Yuan.

At the end of the Yuan Dynasty and the beginning of the Ming Dynasty, all kinds of wastes were waiting for prosperity, and the common people finally had a better life. Would it be possible to increase taxes for them?
As for the commercial tax, this is not something that Zhu Qi can decide on alone.

All in all, the promotion of these subjects is extremely complicated. The best way is to conduct education on a pilot basis in a small area. With a pilot experience, it can be promoted.

Mathematics is very good, with a pen and a piece of paper, the little head will turn around for a whole day, of course, it may also be a day of emptying.

After all, with this thing, if you know it, you can, if you don't, you won't. How many heroes hanged on the tree of Gaoshu, it's not just a joke.

It is a little bit more difficult, but mathematics must be promoted first, whether it is the development of rational thinking, or laying the foundation for future scientific reasoning and scientific computing, this is necessary.

Of course, other people don't understand the importance of what Zhu Qi is doing now, it's even no less important than going to Beiyuan.

So when the first white-skinned, eagle-nosed, Middle Eastern-looking Semuren proposed that he would solve the problem of His Royal Highness the King of Liao, and hoped to meet the King of Liao and get important information, the officials in charge at this time did not pay much attention to it. .

Even feeling a little contemptuous of this Semu person, the official thought to himself, this topic was proposed by our brilliant King Liao, and you, Semu person, can do it too?

Especially when he saw the answer given by the Semu man, although it was very similar to the symbols written by His Royal Highness Liao Wang, the official simply couldn't understand it, and he thought in his heart that it must be scribbled.

He didn't scold the Semu person, but asked him to leave his address and then let him go back and wait for news.

It seems that the Semu people didn't live a good life in Ming Dynasty, especially after the establishment of the Ming Dynasty, after the expulsion of Hu Yuan, the distinction between Hua and Yi became the mainstream of society again.

The Han people who have been oppressed for many years are naturally not very friendly to these Hu people.

The Semu man respectfully said some good things, hoping to see His Highness King Liao as soon as possible and get some errands.

The official agreed and was about to report the matter when he met many students and scholars who came to solve the problem.

It is said that His Royal Highness Liao Wang wrote this is a heavenly book, and he is playing charades.

It is also said that what His Royal Highness Liao Wang wrote is actually a painting.

Anyway, what to say.

After all, what Zhu Qi posted was just such an equation, and he didn't explain what it was. Those who don't know Arabic numerals and symbols don't know that this is a math problem at all.

This official was originally a literati, so he chatted with the students and scholars, and after discussing and discussing, he put the answer of the Semu man aside and forgot.

It was Zhu Qixian who had nothing to do, and after waiting for several days with no news, he took the initiative to go to the government office to inquire about the situation, and then saw the answer written by the Semu man on the table.

Zhu Qi picked up the answer and began to read it carefully. The official next to him slapped his forehead, remembering that there was still such a thing that hadn't been reported.

Only then did he hasten to say:

"Your Highness, this is the answer sent by a Semu person earlier. I was about to send it to you, so you came here by yourself."

Zhu Qi didn't say anything, he read it from the beginning to the end, and there was nothing wrong with it.

In the fourteenth century, the development of Arabic numerals was not much different from modern symbols.

Of course, if Zhu Qi wrote a calculus, people today would not be able to understand it at all.

After all, calculus has not been invented yet, and it takes more than 200 years to wait until the star-studded seventeenth century, known as the birth of geniuses in large numbers.

The official originally thought that His Majesty would not care about the random writing of this perverted person, but he did not expect Zhu Qi to nod his head after reading it and said:

"Where is this man? Let him come here."

The official had cold sweat on his forehead, and hurriedly confessed that it was delivered several days ago.

Zhu Qi was a bit dumbfounded. Unlike the modern worship of foreigners, the Hongwu period was really very Han and Tang style, but anyone who didn't look like a Central Plains person was a barbarian, and the Han people became very confident.

Zhu Qi didn't blame the official, but asked the official to notify Semuren to report to the research institute of the Royal Entertainment Center as soon as possible tomorrow.

I also specifically told the officials that if they still encounter people who write such numbers and symbols in the future, regardless of whether they are Han or Hu, they all call to report and the job is over.

Then he left with his hands behind his back.

The official didn't dare to be negligent, and hurried to inform the Semu people.

As for going to inform Semuren personally, Zhu Qi felt that it was unnecessary.

After all, it’s just solving a system of equations. Now in universities in the western world, any college student can surely be able to solve it.

If the other party was Newton, then Zhu Qi would definitely go to greet him in person, but it is not after all.

We are the Prince of Ming Dynasty, we are Party A, and the other party is Party B, there is no reason for Party A's father to invite someone in person.

In the early morning of the next day, Zhu Qi came to the Royal Entertainment Center early, but he didn't expect that the Semu people came earlier than himself.

Shopkeeper He came over and said:

"Your Highness, Semuren came here before dawn, and it's cold outside, and I dare not freeze him, so I can only arrange a room for him to rest.

As a result, the Semu man drank a whole pot of porridge from me, saying that he hadn't eaten for a long time. "

Zhu Qi listened happily and asked:

"He just drank porridge? You didn't give him anything else?"

Shopkeeper He hurriedly shook his head and said:
"I know that he is the guest His Highness wants to invite, so naturally I dare not neglect, and I have prepared some food, but he is unwilling to eat."

"Why? Afraid of being poisoned?"

"That's not true. He said he was afraid that if His Highness looked down on him, he would have no money to pay."

Hearing what shopkeeper He said, Zhu Qi nodded. It seems that this person is not a person who is greedy for petty gains, and it is better to be more honest.

Zhu Qi asked Shopkeeper He to call the man over, while he went to the Daming Royal Research Center to inspect the firearms research and development, while waiting for the Semu man to come.

The hand-operated ink printing machine has entered the mass production stage, and with Zhu Yuanzhang gradually increasing investment, he even opened a Huangzhuang specialized in manufacturing ink printing machines in Yingtianfu.

Of course, this hand-operated ink printing machine will not be sold to the outside world. After all, in the early years of Hongwu, unlike the middle and late Ming Dynasty, the printing industry was liberalized so that ordinary people could participate in it.

Zhu Yuanzhang of the old Jianghu is very careful about the publicity of public opinion.

Not to mention printed books, even what books are printed every year, those books are banned books, and people are not allowed to collect them, etc., they are all clearly listed.

In addition to the ink printing machine, Zhu Qi is most concerned about the improvement and development of firearms.

Now that the landmines made by indigenous methods have been produced, once things like firing pins are conquered, the landmines will be too simple.

As long as the gunpowder and firing pin are in place, you can install whatever else you want.

Get another box, it doesn't matter if it's a pipe or anything else, anyone who steps on it will follow into the box, but this box is just bigger.

As for the power of the landmines, a preliminary test has been carried out with pigs. So far, the effect is good, and everyone has eaten several meals.

Hearing this, Zhu Qi was relieved. As for the on-site testing, there was no need to do anything. Zhu Yuanzhang probably would have killed those explosions in the main city of Yingtian Mansion.

However, the protagonist feels that he is still not at ease with these gunpowder-related things in the Royal Entertainment Center all day long.

But there was no other way, no matter who told Yingtian Mansion not to be his fief, Zhu Qi couldn't buy land around Yingtian Mansion.

After all, the management of the household registration system is very strict these days, if Zhu Qi, the prince, dares to buy land in Yingtian Mansion, what is it called?This is called land annexation!

Isn’t the reason for the destruction of the dynasties in the past dynasties that ordinary people’s land was taken away by landlords and dignitaries, and people rebelled when they couldn’t survive.

During the Hongwu period, Zhu Yuanzhang clearly saw the reasons for the demise of the dynasty, and this is how the military land system came into being.

As for the military field, not Juntian.

So what is Juntian?To explain, the fields that are given to military households to grow and receive less tax are military fields.

And Juntian has another more important attribute, that is, Juntian is not owned by military households. The owner of Juntian is the emperor!
In other words, military land is the land of state-owned assets.

Someone once did this, but failed. That man was called Wang Mang, who was known as a time traveler.

Zhu Yuanzhang is naturally not a time traveler, but he has a thorough study of history, regardless of whether Zhu Yuanzhang is familiar with Wang Mang's specific policies for land reform.

But Zhu Yuanzhang knew that if the dynasty was to be stable, the common people's land must be able to withstand it. At least those ordinary people who served as soldiers, that is, the military households who accounted for the vast majority of Ming Dynasty, had to have land!
Zhu Yuanzhang originally hoped to use this innovative system to ensure that land annexation was prevented from the root.

What's so good about annexing military fields? They are all state-owned assets and belong to the emperor. With an order from the emperor, the general fields can be redistributed without any reason. Presumably no one will move the military fields.

Zhu Yuanzhang's idea was very good, but later history proved that there are policies above and countermeasures below.

The land that should be swallowed up by the military households is still swallowed up, and those who have become officials have intensified corruption and helped the generals annex land.

During the reign of Chongzhen, the escape of military households became more and more serious. All the troops were paid empty-handed. Even the military towns in Liaodong area had a 20% empty-paid ratio all year round. This is an unwritten unspoken rule.

Not to mention that Li Zicheng occupied Beijing, Chongzhen hanged himself, and after the establishment of Nanming, the four towns in Jiangnan had millions of soldiers on paper.

But 80.00% of them are vacancies. Besides, the remaining 20.00% are pitifully small.

The soldiers in the entire four towns were pulled out to less than [-], and there were not any elite troops among them.

In this way, Nanming was still fighting among himself and attacking each other, but he couldn't enjoy the Manqing.

Leaving aside these sad things, in a word, it is still not enough to have the military land system. If you don't use the system, it is equivalent to not having it.

But how to operate, Zhu Qi is not clear, spy supervision?Follow the example of the Tang Dynasty and inspect the national censor system?That can only take one step at a time.

But it's useless for the prince to think so much.

Zhu Qi walked around the research institute and looked at some completed products, such as mines, the latest shortened flintlock guns and so on.

Both the flintlock gun and the matchlock gun are not very difficult, and they can be forged with the current technology of Daming. As for the paper-wrapped bullets, they can be made with eyes closed.

But what Zhu Qi wanted most was a rifled gun.

The most rare thing is the inner spiral barrel that increases the range and progress, that is, the famous rifling, also known as the rifled gun.

The early flintlock guns and matchlock guns were all smoothbore guns without exception, and there was no such thing as rifling at all.

The earliest rifling appeared in the [-]th century, and now it is the [-]th year of Hongwu, which is the [-]th century.

The rifling can be said to be the soul of the musket. With this thing, the power is really like a rocket going straight up.

Of course, rifled guns also have many disadvantages. For example, how long the existence of rifling has many requirements for bullets, and it also requires barrel assembly line production.

The rifled guns that got up early, the reloading speed is very slow, and when you finish reloading, you may be killed yourself.

Therefore, the rifling technology that appeared in the fifteenth century did not become popular until the Miner bullet was invented in the middle of the nineteenth century.

In fact, there is another huge contribution of rifled guns, that is, soldiers finally don't have to wait in line to be shot.

In the past, they lined up to be shot because of something. It was because the accuracy of the muskets at that time was too low, the range was too short, and they were not even as good as archers.

However, it is much cheaper and more convenient to train musketeers than archers. A large number of musketeers must be better than archers.

So when every western country began to have a large number of musketeers, it was inevitable to line up and shoot.

Because you can only be lethal if you ensure that enough musketeers gather together to shoot.

The other party thought so too.

So the scene of queuing up and shooting appeared.

Therefore, rifling is the real soul of firearms!
But rifling is also really difficult. The only way to do it now is to carve the line by hand, but those who can do this must be skilled craftsmen.

Even if the rifling is made, the barrel is still easy to explode, because there is no steelmaking furnace now, and the barrels made are not borrowed steel pipes, but mostly iron firearms.

How many times can this kind of material hold up to the rifling?
It is estimated that two or three times will explode the chamber.

With so many technical problems, Zhu Qizheng was extremely troubled. It seems that he still needs to find an opportunity to practice steelmaking by indigenous methods.

This thing is also a divine tool. The old-timers back then built up earthen kilns one by one, and what could be smelted in them was steel!
I don't know how to fix it, so I have to read the militia training manual. As long as you know how to burn bricks and have iron ore and various ore raw materials, you can build a steel furnace in your hometown in the countryside.

After Zhu Qi listened to Chen Chuwu's one-by-one report, he gave a few words of encouragement, and then Shopkeeper He came over, saying that the Semu man had already arrived.

Zhu Qi put aside all the miscellaneous thoughts in his mind, and then began to concentrate on the problem in front of him, which was the problem of promoting mathematics.

Zhu Qi quickly went back to his room, and saw a bald man who was dressed obviously different from Chinese clothes, standing in the room with his hands in front of him, looking a little stiff.

This man was about forty years old, with a hooked nose, white skin, and brown curly hair. He looked quite similar to those refugees in the news of later generations.

This is what Daming commonly called Semuren.

Zhu Qizheng was thinking of showing him a few words of English to scare him, but he didn't expect that the other party said directly in the extremely proficient Ming Mandarin, which is Nanjing dialect:
"Caomin, pay homage to His Royal Highness King Liao."

Then he knelt down and kowtowed proficiently, with his tone and movements, if it wasn't for the fact that this person looked like a Caucasian, Zhu Qi would have thought that he was a native of Ming Dynasty.

Good guy, I was really taken aback.

But the other party can speak Chinese, so it’s easy to handle. After all, Zhu Qi’s English level is half-baked, and he can FUCK YOU ASS, OH YEAH and the like. He mainly learns foreign languages ​​by watching videos while doing needlework.

As for where you said the benefits of the time traveler went...

What the hell can I do about falling asleep as soon as I arrive in English class?

Zhu Qi nodded, sat down, and then said to the left and right:

"Give a seat."

Gao Jin quickly brought a stool over and asked the perverted person to sit down. Zhu Qi didn't hesitate, went straight to the point, and checked the household registration.

This color-eyed person also knows everything and says everything.

Like Marco Polo, he is a businessman from Venice. His real name is Alessandra Piero, and his Chinese name is Ma San.

It was precisely because he read Marco Polo's travel notes that he came to the East to explore, looking for the legendary kingdom full of honey and gold.

However, his luck was not as good as that of Marco Polo. When Marco Polo came, it was the Yuan Dynasty where all races were integrated, and the ruler was the gentle and talented Kublai Khan.

With the care of the Emperor of the Yuan Dynasty, he became an official and traveled around the world under orders, so it can be said that he lived the life of a master.

It is precisely because of this that Marco Polo's guerrilla can be written so attractively.

Good guy, you are a master in a feudal society, and you are exploiting people until you are almost inhuman. If you are not happy, then what else is happy on this earth?

But Ma San was not so lucky. He came just in time for the war at the end of Yuan Dynasty.

At this time, Hongwu has been established, and Zhu Yuanzhang will not let a foreigner become an official easily, let alone you, a foreigner, have no extraordinary skills.

Ma San wanted to go back just like this, but he was not reconciled, so he stayed here for five years, and his Chinese was already very slippery.

Zhu Qi doesn't think anyone who is able to learn Chinese successfully by himself is stupid.

After further questioning, I found out that Ma San had graduated from the University of Bologna.

Good guy, the University of Bologna is the first university in the world, and it also has the best teaching quality in Italy. The academic level of graduates here is not bad.

Zhu Qi regained his energy all of a sudden, he didn't expect to meet such a useful foreigner at the beginning.

After Ma San introduced himself, he was also a little apprehensive, wondering how His Royal Highness King Liao would treat him.

He heard His Royal Highness Liao Wang in front of him ponder for a while, and asked:

"Alexander, do you wish to become the second Marco Polo?"

Ma San's eyes lit up, of course he thought about it, and immediately knelt down again, and shouted in the smooth Nanjing dialect:
"If His Royal Highness the King of Liao is willing to give the opportunity, the grass people will die!"

Good guy, Zhu Qi is so proficient in using idioms, and Zhu Qi is not a joke, nodded and said:

"Okay, since you are willing, I will give you this chance."

Zhu Qi stood up, looked at the craftsmen outside, and said:

"You have one month to teach them mathematics!"

Ma San was taken aback, and asked:

"Your Highness, to what extent do you want to teach the mathematics you are talking about?"

Zhu Qi had been prepared for a long time, and took out a book and threw it on Ma San's desk. It was a math book for the first year of junior high school that he had recently written from memory.

"Just this one will do."

(Please make a full order! It's on the recommended position, and it will start to explode!)
