"How is this possible?"

As soon as Gao's words were finished, Yang's side had already exclaimed.

Since ancient times, the people of the world have relied on the sky for food.

As long as there is a slight natural or man-made disaster, the people will either have no harvest or be displaced.

In order to survive, these people naturally beg for a living.

If we want to make all these people disappear, we must first solve the problem of natural disasters.

In this way, wouldn't His Royal Highness King Jin want to go against the heavens?

Gao smiled and said: "At first, my sister didn't believe it, but seeing that there were no more floods and droughts in Bingzhou in the past two years, my sister believed it a little more. ”

After hearing this, Yang carefully recalled the situation in the past two years.

She soon discovered that the state had not been affected by the disaster since the ninth year of Zhenguan.

Even the great drought in the ninth year of Zhenguan did not affect Bingzhou.

So she asked, "How did you do all this?" ”

Gao said: "Naturally, it is to build water conservancy and build dikes.

In the past two years, the largest investment in the state has been in this area, and people are building it almost every day except when the farming season is busy. ”

After hearing this, Yang said with some concern: "With such frequent conscription, the people are afraid that they will have resentment, right?" ”

Gao said: "Sister thinks badly, the craftsmen used in these projects are all hired for money!"

Now that the people near Bingzhou are too late to be happy, how can anyone have resentment? ”

Yang covered his lips lightly and said, "How much does it cost to hire all the workers to do it?" ”

Gao shook his head and said, "This sister hasn't asked, but it costs a lot of money." ”

Yang said: "Just because this state is the fief of His Royal Highness the King of Jin, he is so willing to spend money? ”

Gao said: "My sister doesn't know this, but I heard that construction is also going on in various parts of the Tang Dynasty at the moment, and it seems that it is His Highness's proposal." ”

Wu Zetian, who had never spoken, spoke at this time: "In this way, His Highness is still very good to the people. ”

Gao said with a smile: "Your Highness is not only good to the people, but also very good to the officials under him.

A lot of the food in my house is given by His Royal Highness, and I heard that other officials in the state also receive a lot of rewards every year. ”

"The officials of the imperial court have their own national affairs, why did His Highness meddle in this matter?" Wu Zetian asked suspiciously.

Gao said: "In order to build these projects, the state officials have been running a lot.

Therefore, His Royal Highness will pay for some rewards himself, so as not to resentful of the officials after a long time. ”

Yang said: "I didn't expect His Royal Highness to be a man at a young age. ”

Gao smiled: "It's not! Otherwise, how could His Highness sit on the position of Zaifu at such a young age. ”

The Yang family had a deep understanding of Li Zhi's current status, so after hearing this, he nodded clearly.

Wu Zetian asked with some concern: "Your Highness is so noble, you won't look down on our mother and daughter, right?" ”

Gao said: "Niece, rest assured, His Royal Highness will not do such a thing in the future." ”

Yang said: "My mother and daughter have no strengths, and they are a drag after all. ”

Gao said with a smile: "Sister-in-law doesn't need to worry about this, Your Highness is still in an orderly manner in handling state affairs, wouldn't it be easy to arrange your mother and daughter?" ”

Gao's words made Wu Zetian's mother and daughter feel a lot more relieved.

Li Zhi, who thinks that he can put the people of the world in his heart, should not embarrass them.

Li Zhi, who the three were talking about, compiled a few books at home and handed them to Liu An to print.

He himself took Chai Long and Duan Shizi to the academy outside the city.

The royal children have been here for a short time, and it is time to find out about them.

After Li Zhi came to the academy, he first walked around the outside of each classroom, and then found Yuan Tiangang to inquire about the situation.

When he heard that several princes were quite obedient, Li Zhi said to Yuan Tiangang: "This king is not very interested in astronomy.

If the master has any understanding, he can also write a book and pass it on to future generations.

You and Master Li Chunfeng can also discuss more together.

Astronomy is related to the rise and fall of agriculture in the Tang Dynasty, and it is more conducive to sea navigation.

The king has sent people to various countries to collect astronomical achievements, and I hope it will be helpful to the master's research. ”

Yuan Tiangang said with a smile: "Thank you, Your Highness, Xiaguan and Master Li have really discovered recently." ”

After listening to Yuan Tiangang's words, Li Zhi said "oh" and said, "Master, come and tell me what you found?" ”

Yuan Tiangang said: "The two of us have discovered new evidence for the earth circle theory. ”

Li Zhi's eyes lit up after listening to Yuan Tiangang's words.

He had long proposed the concept of the earth circle theory to Yuan Tiangang, but he had never been able to come up with a specific method of argumentation.

just vaguely put forward a concept of latitude and longitude for Yuan Tiangang to explore by himself.

Now that he heard that Yuan Tiangang had found new evidence, he hurriedly said happily: "What kind of evidence is it?" Come and talk to the king. ”

Yuan Tiangang did not speak immediately, but directly took Li Zhi to his public house.

After coming here, Yuan Tiangang immediately took out a picture scroll from his bookcase.

Li Zhi waited until Yuan Tiangang opened the scroll, and immediately saw some punctuation and line segments that looked very messy on it.

Li Zhi observed it carefully and then said, "This seems to be a star map?" ”

Yuan Tiangang nodded and said, "As His Highness said, this is a star map, but there are also differences observed in different geographical areas. ”

Li Zhi's knowledge of geography has basically been returned to the teacher.

Therefore, after listening to Yuan Tiangang's words, he immediately spoke: "Please also ask the master to explain it in detail." ”

After Li Jing listened to Li Zhi's words, he began to explain to him.

This is the data that he and Li Chunfeng used the funds of the college to arrange for manual measurements.

At that time, nearly 100 observation points were set up within a range of 10,000 miles in the southeast and northwest directions.

These people observed in detail the distances of several major celestial stars from the ground and recorded the angles.

At the same time, they also calculated the angles between their distances based on their own positions.

And Yuan Tiangang and the others combined these data and calculated the latitude and longitude that Li Zhi said according to the algorithm of 360 degrees.

Although Li Zhi didn't understand Yuan Tiangang's explanation very well, he thought of an important question.

I heard him ask, "Have you ever found the circumference of the earth?" ”

Yuan Tiangang opened his mouth and said: "According to the measurement method provided by His Highness, it should be more than 80,000 li. ”

Li Zhi frowned and said, "Is there only this one data?" ”

Yuan Tiangang said suspiciously: "Your Highness, what questions do you have?" ”

Yuan Tiangang was a little uncertain when he said this, and he didn't know whether the result he came up with was right or wrong.

Li Zhi knew in his heart that the ball was not round, but he couldn't show evidence at this time.

So he had no choice but to shake his head and say, "This king can't say it now, but I feel that there is still a need to study it." ”
