Chen Xi carefully read all the calculation methods and verification methods on the manuscript sent by Gan's family, and no longer knows what to say. Although there are some differences in the data produced by each calculation method, it is generally around 40,000 kilometers.

Seeing this is data, Chen Xi basically knew that the Gan family was limited by their former values ​​and could not believe in this thing, but they also had a clear idea of ​​what they calculated by themselves, and based on these things, there was a ball under their feet, which was basically enough to prove it.

The reason why the Gan family is about to be divided is afraid that it is only because of years of education that they are difficult to accept, but as long as the methods and processes are approached, the results are all unreasonable!

Chen Xi thought about it and nodded to Cai Yan. Cai Yan's face turned bitter in an instant. It was obvious that Cai Yan had calculated it, but she couldn't accept it mentally, so she came to find Chen Xi.

"Then why can we stand on it? What about them?" Cai Yan was silent for a while and said, looking at the sky naturally, then looked at Chen Xi. There was a ball under his feet. There were so many balls in the sky, so tell me if I could think more?

"Well, this is a very complicated question. I know how to calculate it, but I can't make it work. Let others explain it. Judging from the situation, someone may be able to solve it within a few decades." Chen Xi sighed and said with a sigh.

"Thank you." Cai Yan was a little silent. Some things were really shocking when he first learned about them, especially for an adult, especially this kind of thing was calculated by himself.

"You have a break, and the Gan family in Moling comes to ask you, and you will tell me the truth. If they ask why, you will ask them to go back and study the trajectory and cycle of the stars in the Ganshi Star Sutra, and let them study the internal connections by themselves." Chen Xi sighed and said, afraid that Cai Yan was also very tired, and his three views were shattered.

"I'll leave first." Cai Yan stood up and shook slightly. It should be due to the hypotension caused by sleepiness, but she still stood up very steadily and stepped back slightly to bow to Chen Xi, and then left.

After Cai Yan left, Lu Xun, whose head was in chaos, finally reacted. He seemed to have heard something that was very inconsistent with what he had learned for many years, so he pointed at the stack of manuscript paper with his fingers and asked, "Master, is the earth under our feet a ball?"

"Yes!" Chen Xi sighed and said, always feeling that this answer would make people helpless. He thought that there was only a ball under his feet, and there were countless balls in the sky. When he looked up at the starry sky, a blasphemy thought would really arise.

However, it is not right to say it is blasphemy. When mortals realize that there is a ball under their feet and there are countless balls in the sky, looking up at the stars is not only blasphemy, but also a journey.

"Then why does it look so flat?" Lu Xun murmured to himself, still unacceptable, but the unreasonable part of the mathematical method is here. Proof is proof. When faced with the unscientific results calculated by mathematics, experience can only bow its head.

When Chen Xi heard this, he couldn't help but think of a joke and replied naturally, "Because it's too big, it looks flat!"

After sending the dizzy Lu Xun, Chen Xi sighed. Huntian said that it has been three hundred years since Luo Xiahong proposed it, and that it has been nearly a hundred years since Zhang Heng used it to explain most astronomical phenomena. However, the people of the Central Plains really never thought about what the ball in Huntian said was really the earth under their feet.

Now some people have really calculated that there is a ball under their feet. Next, this group of people will probably ask why they did not fall as a ball. As a family that has transformed from a noble family in the Spring and Autumn Period, these families can consume generations of people for a problem as long as they are necessary.

In order to observe comets and to determine the cycle, some families even spent several generations in this regard. They were both because of their free time and the extension of family education. Just thinking about how terrible aristocrats who were truly interested in a certain thing are.

As a nobleman who does not need to make up for food and accommodation and life, once he really becomes interested in something, they don’t mind spending a lot of youth. After all, for these people, it is actually just a kind of life to be furious, to bully men and women, and to harm one side.

After raising interest research to a part of life, these people will sooner or later come out. Think about Zhou Shu, Zhou Qun, and Zhou Ju, fathers like astronomy, so they began to study. After giving birth to a son, they began to study. When the son gave birth to a grandson, they continued to study with their grandson.

This kind of intoxication, this kind of teaching by words and deeds, and living in this atmosphere, I feel inexplicably a bit scary. However, in this era when there are basically no entertainment programs, it may be really boring not to find something that can interest you.

But then again, in this era, those who are truly bored are the nobles, the children of wealthy families, and ordinary people who work hard all day long, have no time or energy at all. This is why few people who truly left their names in ancient times were truly poor.

After all, research also requires time, energy and wealth. Just think about it, for a calculation, the Gan family evaporated nearly 200 million yuan in just half a year, so we can know that scientific research is really not something that poor people can afford to play.

Not long after Cai Yan returned home, the Gan family sent someone to visit Cai Yan. It was obvious that the Gan family was really anxious, otherwise, they should not have done such rude things.

Looking at the sleepy man in front of him, Cai Yan sighed, thinking that she probably had the same face in front of Chen Xi before.

"Cai, can you tell me the answer?" Gan Yu said with a faint feeling. As for Cai Yan's appearance, he didn't even have the heart to observe. For the Gan family, which is now full of brains, what kind of beauty and wealth are not as important as the answer we want.

"Well, the answer you calculated is correct. There is a ball under our feet." Cai Yan said with emotion. In front of her, few men showed such a look that they didn't see her. Even Li You and Jia Xu would have some expressions. After all, everyone has a love for beauty, and at most some people control it better.

"It's a ball..." Gan Yu's eyes were like a tumultuous person when he heard this, and a kind of fatigue rose from the bottom of his heart, and then his legs became weak and he fell into the chair.

Gan Yu participated in the experiment, and even one of the calculation methods was proposed by him, but even if they calculated it themselves, they would find it difficult to accept it when they really got the answer. After all, this is really shattering their views.

Cai Yan looked at Gan Yu who was completely silly and said nothing. She just waited for the other party to wake up and quickly stabilized her mentality for convenience.

"My father, please forgive me. I was so excited before, and it was really hard to accept." Gan Yu stood up and bowed to Cai Yan with his fists.

"No need to do this, I was afraid that it wouldn't be much better at that time." Cai Yan didn't care too much about Gan Yu's rudeness. To be precise, it was expected that such a thing would happen.

"May I Cai, can you tell me why our earth is a ball and we haven't turned it out yet?" Gan Yu went straight to the point after hearing Cai Yan's words.

"Horse Chen did not say that the Gan family read their own classics about astrology, calculate the trajectory and time period, and then think about why everything we see falls on the ground, but the moon is above our heads." Cai Yan said calmly. When he said this, Cai Yan even thought about these questions himself, but there was no answer.

"Thank you for your advice, I'm disturbing you." Gan Yu was rude to Cai Yan again when he heard this, and he didn't even want to stay and drink tea, so he was ready to leave.

In fact, this is no longer an ordinary rude, but Cai Yan is very clear that these people are just like his father Cai Yong back then, but Cai Yong pursues music, while these people pursue the starry sky, but there is no difference in essence.

Cai Yan nodded and ordered several maids who had been beside him to send Gan Yu out, so she went to the boudoir to rest. She had consumed a lot of effort.

On the other hand, Gan Yu returned to the small courtyard of Yecheng where he lived temporarily, and several young people immediately surrounded him. These were the younger generations of the Gan family.

"Let the post station send the draft of our calculations to the Wang family in Lujiang, Chen family in Jiujiang, and Zhou family in Brazil, so that the four of us can meet." Gan Yu ordered everything he knew after everyone came back to his senses.

In fact, the Gan family actually knew that they were right, but they could not believe in this absurd reality at all. However, mathematics was unreasonable. Fortunately, there was a way to verify it. Chen Xi's answer, the statement that a god and man fell into a dream is very scientific and reasonable!

"Then do we still collect crystals?" asked a young man from the Gan family.

"I won't accept it anymore. Find a crystal mine and buy it. This way of collecting crystals is not cost-effective. The cost of buying the mine is lower. We need to be as large as possible." Gan Yu sighed and said. It is not too expensive to say that crystals are expensive, but like the ones that the Gan family requires, it is really too difficult.

To be honest, the Gan family was also forced to make astronomical telescopes. Now the glass produced by Chen Xi is not up to standard at all. The Gan family is forced to use natural colorless crystals as lenses. The difficulty and cost of making this thing are, if it is required to be large enough, it will drive people crazy. First of all, there are not many large crystals themselves, and a crack is a problem with color!
