Ye Feng handed the homonymous essay he had written to an old man dressed as a scholar next to him. The old man looked at it and said, "Come here, throw this ignorant guy out."
Ye Feng thought that at this time, Tongwen was not written yet, and many words that were homophones later may not be homophones now, so they could not understand them.
Ye Feng said anxiously: "Wait a minute, I still have poems." Ye Feng pondered for a while and recited the poems he had written before.
"The flower cat is playing with the orange cat, but the cat has no idea. The two children are not suspicious, so they ask people for information." Ye Feng finished reciting it and smoothed his hair confidently.
The old man paused and said angrily: "Kick him out. You don't even have a name. What kind of poem is that?"
Ye Feng's eyes lit up when he heard this, and he shouted: "Yes, I am adc, I can c in the later stage."
The old man was stunned and looked at Ye Feng with wide eyes. After a long moment, he said, "What nonsense is this? Get out of here."
Ye Feng said angrily: "I..." He paused and thought again, pushed the guard away and said: "Don't touch me. I'll go by myself."

As a result, the guard couldn't help but pick up Ye Feng and throw him out of the door.
Ye Feng got up and cursed: "Dogs look down on people, so don't be arrogant. Wait until I hold a spear and stab your mother."
"Okay!" The people next to him immediately burst into thunderous applause.
Ye Feng thought to himself: "Huh? It turns out that the ancients liked this tune. I should have told you earlier."
At this time, some people walked away silently, talking as they left: "People who talk like this have been kicked out, so let's not go in and be embarrassed."
Ye Feng secretly said: "My words are indeed dirty."
This scene happened to be seen by Qiu Laoer who was waiting in line. Qiu Laoer called Ye Feng and said: "Brother Feng, come and get behind me."
Ye Feng asked in confusion: "Huh? What's the request?"
Qiu Laoer said anxiously: "Come quickly, get in behind me."
Ye Feng said awkwardly: "It's not good that there are so many people."

Qiu Laoer explained: "It's okay, everyone does it, no one minds."
Ye Feng was embarrassed to cut in the queue. He walked into the queue and kept bowing to the people behind him and apologizing, saying, "Sorry, I'll just cut in."
The person behind said politely: "It's okay, everyone has stepped in. You are the only one left."
Ye Feng queued up to the door again. The person in charge of registration looked at Ye Feng and smiled and said, "Why were you kicked out?"
Ye Feng turned his eyes and said, "I'll sign up."
The person in charge of registration said: "You have already registered."
Ye Feng said: "You didn't stipulate that if you have reported it before, you can't report it again?"
The person in charge of registration thought for a while and said to himself: "It seems that there really is no such rule."
Ye Feng then said: "That's all right? Come and register."
The person in charge of registration said: "Then we will go back to the martial arts hall?"

Ye Feng rolled his eyes at him and said: "I am a scholar, a scholar, and I will have all kinds of talents this time."
Because there are relatively few people with horoscopes, and the construction work is generally based on horoscopes, so they are mixed together.
The person in charge said: "Do you think this is a level-breaking game? You have to try every one?"
Ye Feng said disdainfully: "You don't have a rule not to change it."
The person in charge of registration said: "Okay, there are many things to do, and the stars are all in good shape."
Ye Feng said: "That's wrong, Lao Dou, astrological master."
The person in charge was surprised: "Why did you change your name?"
Ye Feng said: "I was watching the sky at night just now, and the name Wo Nendie was not good for me. It is indeed the case today. The name Laodou makes me prosperous."
The person in charge looked confused and hesitant.
Ye Feng glanced at the person in charge and said, "What? Do you have a rule not to change your name?"

The person in charge thought for a while, "This, it seems, really doesn't happen."
The person in charge re-registered and said: "Lao Dou, astrology Baigong."
Ye Feng responded: "Hey, hey, hey, be good."
Ye Feng entered again and came to the Xingxiang Baigong District. He found that people here were standing together in groups.
Ye Feng found a place with few people. There were only two middle-aged people talking to each other modestly.
Ye Feng stepped forward, bowed and knelt down next to the two middle-aged men.
The two were discussing the method of calculating the distance between the earth and the sun recorded in Chapter 8 of Zhoubi Suanjing, and then discussed how high and deep the sky was.
There is a method for measuring the distance between the earth and the sun using the standing pole method: "The summer solstice is 16,000 miles south, and the winter solstice is 135,000 miles south. The pole is used to measure the distance. This is the number of heaven."
"The beard of the Zhou Dynasty is eight feet long, and the sundial on the summer solstice is one foot and six inches long. The beard is called the crotch. The one with the upright dial is the sentence. A thousand miles due south, the sentence is one foot and five inches. A thousand miles due north, the sentence is seven inches per chi."
"As it looks southward day by day, the sundial becomes longer and longer. When the sentence is six feet long, take a piece of bamboo with a hole one inch in diameter and eight feet long. Look at it to catch the shadow. The sky is covering the sun, and the sun is corresponding to the hole in the sky. Looking at it from this, the rate is
Eighty inches equals one inch in diameter."

"Therefore, take the sentence as the head and the thigh as the strand. From the thigh to the sun, it will be sixty thousand miles away, but there will be no shadow on the thigh. From above to the sun, it will be eighty thousand miles. If you want to go to the sun, use the sundown as the sentence, and the sun will be high.
For stocks."
"Sentence, the legs are multiplied separately, and they are combined and squared to eliminate them. When the evil is found, it will be one hundred thousand miles from the side of the thigh to the sun. According to the rate, eighty miles will make a diameter of one mile. One hundred thousand miles will make a diameter of one thousand and two.
One hundred and fifty miles. In the old days, the diameter of the sundial was one thousand two hundred and fifty miles."
The two middle-aged men were talking about the above content. Seeing Ye Feng, a young man sitting next to him, they were a little curious, so they started chatting with Ye Feng.
The two of them reported their names respectively, and one of them said: "I am Zi Shen of the State of Lu."
Another person said: "I am the son of Song Dynasty. I wonder who this little brother is?"
Ye Feng said in a similar way: "I am my father from Chu country."
The two of them immediately said: "Hello, Lao Dou, good Lao Dou."
Ye Feng held back a smile and said, "Yeah, hello, you two."
Song Guozi Wei asked: "I can't tell that little brother Lao Dou is still studying the science of astronomy at such a young age."
The two of them thought that Ye Feng, who sat here with them, was someone who understood astrology. Generally speaking, few young people could achieve success in the study of astrology.

Ye Feng said casually: "I know a little about astrology, but the calculation of the distance between the earth and the sun in the Zhoubi Sutra is wrong. In addition, I can calculate how deep the earth is."
The two were surprised and asked: "How to calculate it?"
Ye Feng said: "First of all, you must know that the land under our feet is round. The depth of the ground is the radius of the circle."
The two of them thought about it and immediately shook their heads and said: "The sky is round and the earth is round since ancient times. What can you say to prove that the earth is round?"
Ye Feng said: "We are on a plain here. If the ground is flat, we should always be able to see this person from the heights."
"In fact, we were watching the army go away from the tower. Finally, we saw the people disappearing from bottom to top, and finally the flag was raised high. This shows that the ground is curved downward."
"In addition, our ground is called the Panding Star. When the Tengu swallowed the moon, it was actually the Panding Star that was blocking the way between the moon and the sun."
"The moon being shrouded in the shadow of Panding Star is the Tengu swallowing the moon, and in this process we can see the semicircular shadow of Panding Star. This can prove that Panding Star is round."
"There is also the change in the shadow of the pole in the "Zhou Bi Suan Jing". In fact, it is also caused by the round shape of the Panding star."
"The sun is much bigger than the Panding star, but it's just that it's so far away from us that we mistakenly think it's not big. The sun's illumination to us is almost a parallel light source in every corner."

The two of them looked at each other after hearing Ye Feng's words. In fact, they had traveled to many countries and read a lot of books. They had already understood this phenomenon, but they had not thought about it before.
Ye Feng's explanation made them unable to accept it for a while, and they were silent for a long time.
Ye Feng looked at them and then continued: "The biggest mistake in "Zhou Bi Suan Jing" is that the angle of the pole shadow changes completely wrong when the ground is a thousand miles away."
The two asked in surprise: "What's wrong?"
Ye Feng looked at them with a smile and said, "Have you confirmed it?"
The two looked at each other, shook their heads and said, "No."
Ye Feng said: "You can let two people go to Ji in Yan State and Rencheng in Lu State, which are 1,200 miles apart."
Zishen of the State of Lu asked: "Why not choose a place that is exactly a thousand miles away? For example, Mou City."
Ye Feng explained: "First, because they are on a line due south and north, and the other reason is that one thousand two hundred miles is exactly one-eighth of the circumference of Panding Star."
"The difference in sunlight angle is exactly 4.5 degrees. The first point is for accurate calculation, and the second point is for convenient calculation."

Ji and Rencheng, which later became Jining City, were on the same line of 116 East Longitude. Ye Feng chose the location at about 40 degrees north latitude and about 35.5 degrees north latitude.
The difference in sunlight angle between them is exactly 4.5 degrees, which is one-eightyth of 360 degrees. The distance between the two places is a little over 500 kilometers.
For the convenience of calculation, it is calculated based on 500 kilometers. It can be calculated that the circumference of Panding Star is 500 times 80, which is 40,000 kilometers.
According to the calculation of "Qin used six feet as a step" during the Spring and Autumn Period, the Qin ruler used a circumferential ruler of 23.1 centimeters per foot. At this time, three hundred steps were one mile, and one mile at this time was calculated as 415 points.
Eight meters.
Convert 500 kilometers into meters and divide by 415.8 to get the mileage at this time. It is 1,202.5 miles. But it is not necessary to calculate so accurately, so we take a value of about 1,000
Two hundred miles.
Ziwei of the Song Dynasty asked: "Why is one thousand two hundred miles exactly one-eightyth of the circumference of Panding Star?"
Ye Feng patted his head and said to himself: "I forgot to tell them the calculation method. I just told them the result."
Ye Feng explained sheepishly: "We divide the circumference of a circle into 360 equal parts."
"A straight line is extended from the points on both sides to the center of the circle. The angle formed by this angle is calculated as one degree. In other words, one degree corresponds to the distance between two points on the surface of the circle being one-third of the circumference of the circle."
Ye Feng drew a circle on the ground, clicked two points, and drew two straight lines connecting the centers of the circles.
Original text. From Tadu
"A circle can be extended from the center to two points on the circumference to draw two straight lines and an included angle. Then if we know the distance between the two points and the included angle, we can calculate the circumference of the circle."
Zishen of the State of Lu asked: "Why was it divided into three hundred and sixty parts?"
Ye Feng said, "Uh." Ye Feng rolled his eyes and explained: "Because it is easier to achieve quartering and sixth equaling a circle."
The two nodded after hearing this, but felt that dividing into six equal parts was not very easy.
Ye Feng continued: "Then we know that the distance from Ji to Rencheng is 1,200 kilometers, so as long as we know the angle between these two places extending to the center of the circle, we can know the circumference and radius of Panding Star."
After the endless coma, Shi Yu suddenly stood up from the bed. If you want to see the latest chapter content, please download, the latest chapter content is free without ads.

He took a deep breath of fresh air, his chest trembling.
Confused, confused, and all kinds of emotions came to my mind.
Where is this?
Afterwards, Shi Yu subconsciously looked around and became even more confused.
A single dorm?
Even if he was successfully rescued, he should be in the ward now.
And my own body...how could I not have any injuries at all?
With doubts, Shi Yu's eyes quickly swept across the room, and finally his eyes rested on a mirror beside the bed.
The mirror showed his current appearance. He was about seventeen or eighteen years old, and he looked very handsome.
But the problem is, this is not him! Download the Star app, the latest chapter content is free and ad-free
My previous self was a handsome young man in his twenties who had been working for a while.
And now, no matter how you look, this appearance is that of a high school student...
This change left Shi Yu stunned for a long time.
Don't tell him that the operation was successful...
My body and appearance have all changed. This is not a matter of surgery or not, but magic.
He turned into a completely different person!
Could it be...that he traveled through time?
In addition to the mirror placed beside the bed, which was obviously not feng shui-friendly, Shi Yu also found three books next to it.
Shi Yu picked it up and took a look. The title of the book instantly silenced him.
"Essential Animal Breeding Manual for Beginner Breeders"
"Postpartum Care of Pet Pets"
"Evaluation Guide for Interracial Beast-Eared Girls"
Shi Yu:???
The names of the first two books are pretty normal, but what happened to the last one?
"cough."
Shi Yu looked solemnly and stretched out his hand, but his arm soon stiffened.
Just when he was about to open the third book and see what it was about, his brain suddenly felt a sharp pain, and a large number of memories came flooding back.
Icefield City.
