Daming: Teach the prince about dragon slaying skills at the beginning

"It is said that when a sage was born, the vision of heaven and earth followed him."

King Zhu of Zhou suddenly said such a sentence without beginning or end.

However, this sentence made the princes even more silent.

Compared with the illusory theory of heaven, ghosts and gods, they are more familiar with the theory of saints.

Other things aside, they are very clear about the legend of the Confucian saint Kong Sheng.

According to legend, when Confucius was born, and when he explained the principles of self-cultivation, family governance, and world peace to 72 sage disciples, various visions of heaven and earth appeared.

What kind of dead tree is in spring, what iron tree is blooming, what kind of bird is facing the phoenix...

Thunder from the sky is just one of them.

However, if Yan Changqing is really the legendary saint who came into the world, then they don't know how to deal with it.

The saints in the legends are all very lucky.

If ordinary people treat it badly, it is not impossible for them to damage their own luck and encounter unknown circumstances, or to fly into disasters and die suddenly on the spot! ! !

At least the legendary saints have such abilities!

After a long silence, Yan Wang Zhu Di said with a little determination:

"I'll send someone to watch him at the same time, just watch him, don't touch him for now, and at the same time make sure that he won't be disturbed by anyone except us!"

"Afterwards, let's go find Big Brother and tell Big Brother what happened today."

"Didn't he say he wanted to teach us dragon slaying skills?!"

"In that case, let's go and listen with Big Brother to see what he can teach us."

The eyes of Qin Wang Zhu Xi, Jin Wang Zhu Wei, Zhou Wang Zhu Wei, Chu Wang Zhu Zhen, and Qi Wang Zhu Wei all had thoughts of contemplation flashing through their eyes.

They naturally understood the meaning of Zhu Di's words. Today's incident involved the so-called "dragon slaying technique", so they couldn't pretend that nothing happened anyway.

And to put it in a bad way, even if they are princes or princes, they are not qualified to deal with things like "dragon slaying skills"!

Ever since Yan Changqing uttered the words "Dragon Slaying Skill", there are only one and a half people in the whole world who are really qualified to deal with him!

One is today's son, their father, Zhu Yuanzhang!

The other half is naturally the present prince, their eldest brother - Zhu Biao!

Only the two of them are qualified to make decisions about Yan Changqing!

But just because of the undetermined word "Dragon Slaying Skill", it is more or less a big deal to startle their father who is busy with everything.

So the most appropriate thing is to tell Prince Zhu Biao about this matter, and then invite Prince Zhu Biao to listen to Yan Changqing's so-called "Dragon Slaying Technique" together!

In this way, even if something really happened in the end, when their father asked, the prince Zhu Biao could still support them in front, and they didn't know that they didn't report it.

After pondering for a while, King Qin Zhu Xi was the first to speak:

"I agree with the fourth brother's opinion, what about you?"

"Me too."

"I also think what the fourth brother said is reasonable."

"Just do what the fourth brother said."

"I think that's the best way too."

King Zhu of Jin, King Zhu of Zhou, King Zhu Zhen of Chu, and King Zhu of Qi all agreed.

"Since that's the case, let's go to the palace to find elder brother."

Seeing that his younger brothers agreed, Qin Wang Zhu Xi immediately decided to go to the palace instead.

As for today's Guozijian lecture, it doesn't matter if you don't listen!

Right now, nothing is more important than Yan Changqing's "Dragon Slaying Skill"!

Chapter 3: Zhu Yuanzhang who was known for the first time

When King Zhu of Qin, King of Jin, Zhu Di, King of Yan, Zhu Di of Zhou, King of Chu Zhuzhen, and King of Qi Zhu Wei entered the palace to look for the prince Zhu Biao, Zhu Yuanzhang in Fengtian Palace had already received it first. information.

In other words, Yan Wang Zhu Di and the others still underestimated their father's Royal Guards.

When the princes had just sat on the sedan chair and got up and walked towards the palace, among the prince's guards, a few guards had already quietly disappeared into the crowd without causing any disturbance.

Although not many people know what happened outside the Imperial College before.

But all the prince's guards who were in charge of protecting the prince heard it with their own ears.

And among these prince's guards, how many of them are Jinyiwei, I am afraid only Zhu Yuanzhang knows.

Normally, the prince's guards transformed by Jin Yiwei are no different from ordinary prince's guards. They are the most trustworthy subordinates of the princes, and they are willing to give up their lives in order to protect the princes.

But when something happened, these prince's guards would turn into the original Jin Yiwei, and pass back to Zhu Yuanzhang the news they heard and saw word for word.

For example, what they heard about the "dragon slaying skill" today and the horrifying scene of the nine thunderclaps they saw were worthy of reporting to Zhu Yuanzhang.

In the study room in Fengtian Hall, Zhu Yuanzhang looked at the memorabilia that Jin Yiwei had just hurriedly handed over on the table in front of him, and a thoughtful look flashed in his eyes.

The content described in the memorandum is not much, the main thing is that Yan Changqing told the princes that he has the knowledge of "dragon slaying skills", and after the words fell, the terrifying and shocking scene of nine thunderclaps fell one after another.

As well as the decision of the princes, and the decision of the prince Zhu Biao to go to Yan Changqing with the princes two days later to hear what he said about the "dragon slaying skill".

Zhu Yuanzhang had never heard of Yan Changqing before.

Even before today, he didn't have the slightest impression of the name Yan Changqing.

After all, in the final analysis, Yan Changqing was just an insignificant doctor of mathematics from the ninth rank of the Imperial College, and he was the lowest existence in the Ming Dynasty's ninth rank and eighteenth rank official system.

If he has an impression of such a humble official, then he has seen a ghost.

However, such a doctor of arithmetic from the ninth rank dared to say that he had the knowledge of "dragon slaying skills" to teach a group of princes, and even when he fell behind, it seemed that he had the help of thunder and heaven!

Whether such a thing is true or not, it is worth Zhu Yuanzhang's thinking about it.

"Mao Xiang."

Zhu Yuanzhang looked outside the study and said lightly.

"Chen is here!"

The commander of Jin Yiwei, Mao Xiang, entered immediately.

"Check out Yan Changqing, a Ph.D. in mathematics from the Imperial College, and within an hour, I want to see all his information."

"Yes, Your Majesty!"

But in an instant, all the information about Yan Changqing had been presented on Zhu Yuanzhang's table.

When he saw the news reported by Jin Yiwei before, he had sent someone to collect Yan Changqing's information at the first time, so that he could present it at this moment.

Zhu Yuanzhang glanced at Mao Xiang approvingly, and then opened the information records about Yan Changqing.

"Yan Changqing, born in the 12th year of Zhizheng."

......

"Parents are dead, no relatives, no friends."

......

Seeing these personal and family related information, Zhu Yuanzhang frowned slightly and continued to look down.

"In the ninth year of Hongwu, he served as an assistant teaching assistant of Guozijian. In the tenth year of Hongwu, he competed with two doctors of mathematics in Guozijian, and they both won. Both doctors of mathematics treated them with the courtesy of teachers, and voluntarily reduced them to teaching assistants. Therefore, Yan Changqing was promoted to PhD."

"After being promoted to a doctorate, the teaching method is very different from other doctorates, but it is very popular among Guozijian students."

"If you have a three-quarter-hour class, you will have a quarter-hour break; if you have a two-hour class, you will have a half-hour break."

"I often lead the students of the Guozijian to do various experiments and researches. I once saw the pole of the boat first and then the hull of the boat in the rivers, lakes and seas, and proved that the earth is a sphere."

"I also demonstrated universal gravitation by throwing objects up and down to the ground, indicating that the earth has a gravitational force, and it is precisely because of the existence of this gravitational force that binds all things that all people and all things on the sphere of the earth are not thrown away. "

"I also calculated the circumference of the earth to be [-] li by calculating the sunshine projection of poles in different places."

......

Zhu Yuanzhang couldn't help but frown even more when he saw the incomprehensible, even unimaginable experiments and demonstration methods recorded on it.

Because he couldn't understand a lot of what was said above, and it was even a little difficult to understand.

However, the methods of argumentation written above are extremely simple, credible, and well-founded.

Apart from other things, Zhu Yuanzhang believed in the fact that the earth is round by seeing the pole of the boat first and then the hull of the boat on the rivers, lakes and seas.

Because in the past, when he was competing with Chen Youliang for the world, Chen Youliang's lake boat was mighty and mighty, coming from a distance.

At that time, the first thing they saw was the mast of the boat, and then the hull.

If the earth is flat, then the first thing you see must be the hull of the ship. Only when the earth is round can you see the mast first and then the hull.

As for other ways of proving that the earth has gravitation by throwing objects up and down, and calculating the circumference of the earth through sunshine projection, Zhu Yuanzhang couldn't understand the mathematics involved because it was too professional.

But in general, Zhu Yuanzhang was barely able to confirm the calculation of the other party, or it was very likely that what he said was correct.

Zhu Yuanzhang continued to look down:

......

"Today, the Guozijian sacrificed wine to Kong Kebiao, and Yan Changqing was kicked out of the Guozijian on the grounds that he violated the teacher's example, misunderstood his children, and corrupted the Guozijian's style of study."

......

Soon, Zhu Yuanzhang had read all the past information about Yan Changqing.

After reading Yan Changqing's information, Zhu Yuanzhang keenly realized that aside from other aspects, Yan Changqing is definitely a great talent in mathematics and other related aspects!

And if the other party is a great talent, then in other words, the "dragon slaying skill" that the other party said is also true? ! !

Thinking of it in my heart, and then thinking of what was written in the memorandum, the other party said a word, and the Nine Layers of Thunder "cheered" for him, even Zhu Yuanzhang couldn't calm down.

Zhu Yuanzhang pondered slightly and then said:

"According to the previous arrangements of the princes, strengthen it again. You are only responsible for watching him, only he will not leave Yingtian Mansion, and everything else will follow him."

"But at the same time, no one is allowed to disturb him except the princes!"

"In addition, when the prince and the others go to listen to the lecture... "Dragon Slaying Technique", I will listen to it without them knowing."

When it came to dragon-slaying skills, Zhu Yuanzhang hesitated for a moment, but he still said it directly.

He would like to hear what kind of knowledge can be called "Dragon Slaying Technique"! ! !

In addition, there is also the "Subduing Dragon Study" that has been studied by tens of millions of people. He is also very curious! ! !

He wanted to see what the so-called "Dragon Slaying Technique" and "Subduing Dragon Studies" were all about? ! !

"Yes, Your Majesty!"

The commander of Jin Yiwei, Mao Xiang, responded immediately, turned around and retreated to make arrangements.

Chapter 4: Hong Wu's mathematics level is not as high as junior high school students

In the heavy rain, Yan Changqing walked for more than half an hour before returning to his residence in a remote corner of Nanjing City.

Compared with other sixth-rank and third-rank officials, with his previous doctorate in mathematics from the ninth rank, he can only afford a house in this corner at most.

Although the house is not big, it is quiet and elegant. Even the end of the Qinhuai River is not far away, so it can be considered a beautiful scenery.

As soon as he got home, Yan Changqing put a bucket of hot water for himself, and then immersed himself in the hot water.

In the misty heat, I thought about my life this past year.

A year ago, he traveled to the beginning of the 11th year of Hongwu, Daming, and became an assistant teacher of mathematics at the Imperial Academy.
