Gou in Daming, I was overheard by Zhu Yuanzhang

The person who came was engraved by Dr. Zhang of Qin Tianjian.

Of course, this doctorate is not a degree, but an official position, from the ninth rank.

Zhang Kezhi came to invite the young prisoner under the order of Zheng Wuru, the supervisor of Qin Tianjian.

"Oh, look, teacher. I'm an official now. In my position, I have to seek my own government. Now it's working hours, and I can't stay at home all the time. I have to go to the office no matter what."

What Zhu Yunxi said was righteous and strict.

Fang Xiaoru felt that King Wu's knowledge was superficial and his skin was really thick.

Now that you're an official, don't you know what level of official you are?
Can a young prisoner with a sixth rank be worthy of your title of King of Wu?
Can't stay at home all the time?Thank you for being able to speak.

Every day I get tired of lying in this yard, being taken care of by two maids.

Now you say you're going to Dianmao!
It is clearly avoiding study!

Of course, he is only a teacher in name.The purpose is not to teach.

Fang Xiaoru readily agreed to King Wu's request to go to work.

Going out with Zhang Kezhi, Zhu Yunxi felt that he was going the wrong way. Why did he go to the palace?
"You Qin Tianjian, where is the office?"

"Qin Tianjian is naturally the closest to the sky. Therefore, Qin Tianjian is the closest to the emperor's residence."

The chapter is engraved with pride.

It is true that Qin Tianjian is the closest to the sky, but it is far-fetched that you are the closest to the emperor!
Putting the sky and the son of heaven together is pure bullshit!
But from the emperor to the common people, they all believed in this.

I thought that by choosing Qin Tianjian, I could hide from the court from now on!
Who knew that Zhu Yuanzhang was even closer!

"In the Qin Tianjian, all of us have to be on duty at all times. Because the emperor wants to ask about the celestial phenomena, weather, and time at any time."

"Qin Tianjian, the top is related to the sky, and the bottom is connected to the people. Not to mention anything else, if the weather forecast is not accurate, it will delay the farming season and delay the food."

"King Wu said in the hall that Qin Tianjian's superiors and Tiantong, and his subordinates are equal to the people. His words are really accurate, and we all admire them."

Zhu Yunxi's heart is stuffed!

Always in place!

Old Zhu would always ask.

In the future, how can you skip work?

"You Qin Tianjian, don't you set up some kind of observatory outside the city, and set up a few more points to measure the wind direction, temperature and so on?"

Qin Tianjian said no.

Zhu Yunxi is very sorry, if there are observatories and other facilities outside the city, then he can go to work in these places with integrity!
Who knew that Qin Tianjian didn't even have an observatory!

Enter the palace, pass the Hall of Mental Cultivation, and then arrive at the Qin Tianjian.

It is really too close to Zhu Yuanzhang!
Why didn't you notice it before?
As soon as he passed the Hall of Mental Cultivation, Zhu Yuanzhang appeared, as if he was waiting for him.

"Third grandson, come, come with us to the Qin Tianjian."

Zhu Yunxi was heartbroken again!
"What's the matter with Lao Zhu, it's like dog skin plaster and brown sugar, it won't come off if it sticks!"

"Go to work, Lao Zhu is pestering you!"

"Don't go to work, there is another idiot Fang pestering you in the yard!"

"How are you doing these days?"

"Qin Tianjian's group of people will talk like gods and gods, and they can't do anything!"

"This group of people should be the scientific elite of the Ming Dynasty!"

"Why don't you even have an observatory, at least your entire observatory."

"No matter how bad it is, we have to set up a few more points inside and outside the city to measure the atmosphere and temperature?"

"Are you just sitting in the room thinking about it?"

"Is there a doctor of engraving? Just keep a engraving and write down the numbers, and you will become a ninth-rank official?"

"Old Zhu's official, isn't it too easy?"

Zhu Yuanzhang said: "Third grandson, Qin Tianjian's people are amazing! At least half of their predictions are accurate."

Zhang Kezhi introduced that there were 22 people in the Qin Tianjian, only two of them were Han Chinese, and the rest were Muslims.

Zhu Yunxi remembered that the Qin Tianjian in the Yuan and Ming dynasties were indeed dominated by Muslims.

The Qin Tianjian ten years before Hongwu was called "Huihui Qin Tianjian".

The group of people Zhu Yuanzhang hired was a group of Arab and Central Asian astronomy and calendar experts who believed in Islam and came to China in the Yuan Dynasty.

The official name of Qin Tianjian is Wu Ru, a Hui Hui, and it is also the name bestowed by Zhu Yuanzhang.

Wu Ru saw that Zhu Yuanzhang personally led the king of Wu, but he didn't understand His Majesty's intention.

In his opinion, Qin Tianjian is extremely sacred, and those scholars are not qualified to enter at all.

Of course, an ignorant waste like King Wu is even less qualified.

Being able to come in is probably to supervise the work of Qin Tianjian.

After walking around in the Qin Tianjian, Zhu Yuanzhang was in a good mood today and stayed with him all the time.

This shocked Qin Tianjian from top to bottom.

Although Qin Tianjian is very close to His Majesty's Hall of Mental Cultivation, His Majesty has never entered it.

If there is something to do, it is always called by someone.

But this time, His Majesty actually went around here, and it must have a lot to do with Zhu Yunxie.

Walking in front of Kelou, Zhu Yunxi's eyes lit up.

"It turns out that the engraving of chapters does not use one, two, three, four, nor counting chips, but 12345 Arabic numerals!"

"Arabic numerals were actually invented by a scientist in Baghdad in ancient India."

"Later, the Arabs conquered the surrounding nations and established Arab countries including the East Indies."

"They found that the mathematics of the conquered peoples was superior to theirs, so they adopted the Arabic method of counting."

"Arabic numerals have brought technology a step forward. Many complex algorithms can be solved instantly with Arabic numerals!"

"These Muslims actually used Arabic numerals!"

"The reason why we declined later was mainly because basic science did not keep up, such as Arabic numerals!"

"Arabic numerals and mathematics must be promoted!"

"Also, geometry, have you mastered these times?"

"Algebra plus geometry, my Ming Dynasty's handicrafts, weapons, etc. will all go up to a higher level!"

"Promoting mathematics is as meaningful as Qin Shi's "Shu Tong Wen, Che Tong Gui!"

"How high is a mountain, you don't need to go to the front to know it!"

"Learn mathematics, physics and chemistry well, and you will not be afraid to travel all over the world!"

"Mathematics, physics and chemistry lead the society forward, let's start from the Ming Dynasty!"

Ah, Zhu Yuanzhang didn't expect that the crooked symbols engraved and missed are so powerful?

These so-called Arabic numerals actually surpassed Qin's Shutongwen and Chetongrail!

Algebra, what is geometry?I dont understand.

But there is one sentence that Zhu Yuanzhang understood.

How high is a mountain, you don't need to follow it to know it!
That's great!For example, the city wall, how high is the enemy's city wall, you don't need to go to the front to know the height!

You can accurately manufacture ladders and observation towers!

Then give it a try?
There is a tall pagoda in Yingtian, the glazed pagoda of Dabaoen Temple, let Qin Tianjian try it?

"Wu Ru, I have something for you. How tall is the glazed pagoda of Dabaoen Temple? You can test it, and you can't ask any insiders, let alone go up to the pagoda."

Zhu Yuanzhang's order made the people in Qin Tianjian look at each other in blank dismay.

Wu Ru bit the bullet and came out and said, "Your Majesty, I'm afraid no one in the Qin Tianjian can do this!"

"Oh my god, what is Lao Zhu going to do?"

"Don't ask the insider, let alone go up the tower! Let me measure the height of the tower!"

"How can the people of Qin Tianjian do it?"

"Old Zhu, is this to develop technology?"

"I thought of Surveying Mountain, and Lao Zhu thought of Surveying Tower!"

"Is this the blood relationship that caused the telepathy?"

Zhu Yuanzhang secretly applauded Xuan, and almost let the third grandson see that he can eavesdrop on the inner voice.

Qin Tianjian couldn't do this, and the third grandson certainly wouldn't stand up.

Even if Wu Ru, the supervisor, is killed, the third grandson will not do anything, because the people in Qin Tianjian have nothing to do with the third grandson.

In this way, the magical measurement method mentioned by Sansun cannot be verified.

How to do?
Zhu Yuanzhang immediately thought of Lan and Chang.

Let Chang Sheng handle this matter!
If you can't do it well, whip it!

At that time, if Chang Sheng can't do it, as a nephew, you just have the heart to watch?
