Wei and Jin cooks

Zhang Pingzi is Zhang Heng. After two hundred years of time and space, Guo Pu unilaterally paid homage to Zhang Heng. Zhang Heng believes that the sky and the earth are like eggs, the sky is like a chicken, and the earth is like an egg yolk, so the sky and the earth are big circles within small circles.

They have differences in the primary theory of the Daxue theory. They both believe that the world is round, but they have different definitions of the details of a circle.

Zhao Hanzhang felt that they could seek common ground while reserving differences.

"...I agree with Ting Han on this point, but whether it is a double circle or a single circle, we can put aside the controversy first. They are all circles anyway, so why not calculate the time of the solar eclipse first?"

Guo Pu: "No, this is an academic dispute, how can we fool it? If he doesn't recognize the double circle, I won't settle this with him."

Zhao Cheng said: "How can the earth star be round? If it is round, how can we stand? The earth star should be a round sky and a flat place."

This person has another theory. Guo Pu objected fiercely, "You can't think that the earth is flat just because you can see it with your eyes. Your argument is worse than even Fu Tinghan's."

Zhao Cheng: "You said the earth is round, what evidence do you have? Even Zhang Heng can't provide any evidence."

Guo Pu was choked.

Yuan Li on the side nodded slightly.

Zhao Hanzhang glared at him: "Why are you nodding? Do you know who Zhang Heng is?"

Yuan Li really didn't know, but he understood what they said. He could understand that the place was round and the sky was round, but he couldn't understand that the earth was round and the sky was round.

However, he could not openly oppose Zhao Hanzhang, so he decided to agree with Zhao Cheng in his heart.

Guo Pu frowned and asked Zhao Cheng, "If the sky is round and the earth is flat, there will always be land that cannot be covered by the circle. Wouldn't it be that the four corners are leaking out? What do you see when you look up at Shi Wutian from the four corners?"

Zhao Cheng: "The sky is so big that you can just pee on the ground."

Zhao Cheng used Guo Pu's point of view to counter Zhao Hanzhang, "If the earth star is a single circle, then what is the sky we see when we look up? Isn't it true that everything is exposed to the universe?"

Guo Pu became distressed, turned to Zhao Hanzhang and said: "I have no evidence to prove that the sky is round and the earth is round. If you and Fu Tinghan have a way to prove it to the world and convince people with such stubborn opinions as Zhao Cheng, then I can temporarily abandon my dissent and like You said, seek common ground while reserving differences.”

Zhao Hanzhang opened his mouth and found that even though she had a sharp tongue, it was difficult for Zhao Cheng and the others to agree with her point of view.

Zhao Hanzhang suddenly thought of a question. Fu Tinghan had so much knowledge of natural science in his mind. She could agree with him, but what about others?

If it cannot be recognized by mainstream intellectuals, and the natural knowledge cannot be disseminated and verified, what use is it even if they know it?

Only with recognition can knowledge be passed on.

Zhao Hanzhang became serious, nodded to Guo Pu and said: "Ting Han and I will find a way to verify that the earth's stars are round, and we live on a circle, there is only one circle!"

Guo Pu couldn't hold it back and argued with her again about single and double circles. He stretched out a finger and pointed upward, "Then what do you think that is? Since we are on a circle, what is going on today? It It’s also round, and it’s covering us right now.”

Zhao Hanzhang asked: "If we have a chicken-like round shell on our heads, how can we see the stars, sun and moon in the universe through this shell?"

Guo Pu was silent.

Zhao Cheng said in time: "The earth is square and the sky is round. As for why we can see the stars, sun and moon through the sky, I don't know."

Yuan Li looked at this and that, and couldn't help but said: "The stars are in the sky."

The three of them said in unison, "Shut up!"

Yuan Li was a little aggrieved, but he didn't feel that he was at fault. The stars were in the sky.

For ordinary people like Yuan Li, Guo Pu didn't even bother to explain to him.

Of course the stars are not in the sky, but outside the sky.

It was Zhang Heng who said: "The surface of the universe is infinite, and the end of the universe is infinite."

Guo Pu's astronomical knowledge is the inheritance of Zhang Heng's theory. Unlike ordinary alchemists, Guo Pu was born in a noble family and had a superior learning environment and abundant learning resources since childhood.

Zhao Cheng knew less in this area, but he still had basic astronomical knowledge. The idea of ​​an infinite universe was not started by Zhang Heng, but existed since ancient times. However, Zhang Heng simplified it and made it more clear. come out.

He is also a teacher, so when Guo Pu was meditating on the question raised by Zhao Hanzhang, he explained to Yuan Li, "Yu is space, with four directions up and down, and there is no limit to the four directions up and down; universe is time, which has the length of ancient and modern times, and ancient and modern times There is no limit to its length.”

"And when the sky ends, the stars are no longer in the sky, but outside the sky, and the same goes for the moon and the sun." Zhao Cheng said: "It is precisely because the moon and the sun are outside the sky that there will be solar and lunar eclipses."

Yuan Li's eyes were confused and he didn't understand.

Guo Pu had already come to his senses, glanced at him and said, "Don't teach him. There are still many stupid people in this world, and not everyone can understand the principles of heaven."

Yuan Li:......

If this were any other minister, he would definitely be angry, but Guo Pu... well, he is indeed a fool in this regard.

"So you and Fu Tinghan think that the sky is a layer of gas?"

Zhao Hanzhang nodded, "Yes!"

Guo Pu frowned and shook his head after a while, "No, I still don't believe it. However, this matter can be put aside for now. For now, let's focus on proving that the sky is round. I don't want to argue with others every time I report on the progress of the almanac. Square is round.”

Zhao Hanzhang lowered his eyes and thought for a moment, "Then there are only two ways to solve it."

Guo Pu's eyes lit up and he asked: "What can we do?"

"The first is to find a ship and go to sea eastward, keep going eastward, and see if you can come back to us."

Guo Pu: "...say the second one."

"The second is observation," Zhao Hanzhang said with a smile: "I think Tinghan must have told you about the latitude and longitude. No one believes it, so let's observe. Observe the altitude of Polaris from various locations to see how they are in different locations. If you calculate the difference in angle, you will find the latitude; since you can calculate the solar eclipse, you must also be able to calculate the lunar eclipse. When a solar eclipse and a lunar eclipse occur, you can calculate the time difference when they appear in different places, and you will find the longitude. .”

Guo Pu opened his mouth wide. This was something Fu Tinghan had not yet had time to tell him. He looked at Zhao Hanzhang suspiciously, "You and Tinghan have tested it and calculated it?"

She had lived for so many years, lived in Luoyang before she was fourteen, and was surrounded by people every day after she was fourteen. How could she lie to him?

Zhao Hanzhang didn't hesitate for a moment and said directly: "I know it in the dream, it was taught in the dream, and I know the destiny."

Others would not believe this, such as Zhao Cheng and Yuan Li, who subconsciously doubted the authenticity of what she said.

But Guo Pu believed it immediately.

He murmured: "I see, no wonder he always knows something that I don't know, and he understands everything you say, and you can understand everything he says. It turns out that he was taught in dreams..." "

Guo Pu's eyes became brighter and brighter, "Huh, he still wants to hide it from me. No matter how I question him, he refuses to tell."

Guo Pu praised Zhao Hanzhang: "The general is still sincere in his treatment of others."

Zhao Hanzhang nodded and accepted his compliment.

Zhao Cheng and Yuan Li:...

What should I do? I'm a little restless. Shouldn't it be that Fu Tinghan is honest and doesn't lie, and the girl...

Bah, bah, bah, Yuan Li suppressed his thoughts and did not dare to express them.

Zhao Hanzhang and Guo Pu said: "Put aside the dispute between the single circle and the double circle. Let's first deal with the differences between the earth's circle and the place. When Tinghan comes back from the Yellow River, I will ask him to give you observation tools. The most urgent task is to calculate the eclipse." The specific time."

Guo Pu then put aside his prejudice and agreed with a serious face.

Fu Tinghan and Zhao Hanzhang believed that a solar eclipse was a solar eclipse and was just a natural phenomenon, but Zhao Hanzhang knew that the ancients would not think so.

For example, Guo Pu, an ancient man.

At this time, he said to Zhao Hanzhang with a serious face: "The sun is the symbol of the king. The sun is blocked, which means that the emperor is no longer suitable to be the king. At this time, even a person with a low level of cultivation like me can figure out the clues. , there is no way to change it, so I can only ask His Majesty to issue an edict to punish oneself, or to abdicate in favor of someone more worthy."

Zhao Hanzhang lowered his eyes and thought for a moment, then said in a deep voice: "Don't mention it in advance. You can figure out the specific time first."

She went back and thought about it to see if she could recall it in her mind.

She had to prepare in advance to avoid accidents.

Tengu's eclipse of the sun is not only explained by the emperor's lack of morality, but also by the treacherous ministers in power.

She has a good reputation among the people, but no matter how good she is, there will always be opponents, so she has to be prepared there in advance.

Zhao Hanzhang told Zhao Cheng and Yuan Li, "This matter is confidential and must not be spread outside."

Zhao Cheng and Yuan Li bowed in response.

Zhao Hanzhang looked at Guo Pu, feeling a little headache.

Zhao Cheng and Yuan Li are both notoriously tight-lipped, otherwise one would not be a good teacher, and the other would not be a good intelligence leader, but Guo Pu...

This is a contradiction.

Call him lax, most people would never get a word out of him; call him strict, after he and Fu Tinghan became good friends, Fu Tinghan would hear all kinds of things from him every time he was resting or bored. Gossip.

Fu Tinghan went back and told her that it could be said that the scope of coverage was so wide and so private that it was simply unheard of.

One of the things that shocked her the most was that when Guo Pu traveled to a place many years ago, he told fortunes for a wealthy landowner. The landowner was very grateful to him and thought he had very good genes, so he asked him to stay in the same room with his wife. Give him the child.

Although Guo Pu liked beauty, he didn't like to keep seeds. He was frightened and ran away overnight. He secretly gossiped with Fu Tinghan, "I don't know how many of his five sons are his, or whether they are all borrowed seeds. It's a pity that I only saw one at that time. By coincidence, judging from his face, that boy was not his real son."

Fu Tinghan:......

He couldn't help but ask Guo Pu, "If you tell me this, aren't you afraid that I will spread the word?"

Guo Pu looked at him with contempt, "Other than General Zhao, who else can you pass on to? You can pass on such trivial matters if you want."

Originally, he and Fu Tinghan said these things just because they were not afraid of Zhao Hanzhang knowing about it. Isn't this a different kind of message?

Therefore, it left an impression on Zhao Hanzhang that he was selectively strict.

Guo Pu met Zhao Hanzhang's eyes and defended himself, "I'm going to be strict about this big thing, okay?"

Only then did Zhao Hanzhang let him go.
