Mythic version of the Three Kingdoms

Chapter 2503 Someone took that step

"Yes, Master, if possible, please give me a map that is accurate enough, a map that is accurate enough to cover the universe." Lu Xun thought for a while and said, "Let me remember it all in my heart, and use it in my future life. To measure, to verify."

Chen Xi couldn't help feeling a lot of emotion when he heard the words, should he really be Lu Xun? This kind of mentality, this kind of ideal is really lofty, but Yu Nei, even in later generations, no one really has an accurate map of the entire Yu Nei, the so-called world map It is also worth the scope of the current human beings, Yunei, look up at the bright galaxy, that is Yunei.

"Okay, I will use a scale to draw you a map with precision and terrain." Chen Xi suppressed his desire for the starry sky and narrowed the map to the world. In this way, what Lu Xun wanted was not It's so difficult, at most it's a bit troublesome, but it's still half a year before he gets married, and Chen Xi still has time.

What's more, after being mentioned by Lu Xun, Chen Xi just remembered that since he can still remember a relatively detailed map of the world, he should combine all the maps in advance to make an accurate and usable map as a reference.

"Thank you, teacher." Lu Xun said happily. He really wanted to see how big this world really is.

"Well, I'll write a letter of greeting to General Huangfu first, and I'll take you there tomorrow." Seeing Lu Xun's expression, Chen Xi smiled and said, "You wait here first, I'll write a letter of greeting to let My old housekeeper sent it over."

Lu Xun nodded, and Chen Xi went to the study first. When Chen Xi came again, the stone table was already filled with all kinds of snacks. Lu Xun sat on one side, while Cai Yan sat on the other side. Chen Ying Be on the sidelines.

"Well, it's rare." Chen Xi was a little surprised to see Cai Yan appearing. To be honest, since the year before last, Cai Yan came to Chen Xi's side less and less. When the second lady got Yang Hu and Yang Hui After Yu, Cai Yan basically didn't come to Chen Xi's side.

"I want to ask some questions." Cai Yan held the teacup in his hand, and said plainly without any ups and downs, which can be regarded as an explanation for those who are not here.

"What's the problem?" Chen Xi asked puzzledly. Generally, Cai Yan would solve problems by himself. In the past, if Cai Yan had any problems, he would seek answers from Chen Xi. Now, it is no longer necessary.

"Molinggan's family took a bunch of things and came to me for an answer." Cai Yan said calmly and coldly.

"Ha, you still do this kind of thing?" Chen Xi said with a look of surprise. He had never heard that Cai Yan still has a hobby of answering questions. It is a bit strange to collect things to answer questions.

When Cai Yan heard this, her cold eyes naturally glanced at Chen Xi. It had no other meaning, but it still made Chen Xi a little embarrassed.

Fortunately, before Chen Xi could speak, Cai Yan had already opened his mouth to explain to Chen Xi, "It's not that I received something and gave the answer to the other party, but that I will help others solve some academic problems. As for whether it is a standard answer, I can only say It's based on my knowledge base."

"..." Chen Xi had nothing to say, Cai Yan seemed to have no opinion of the sect, but because of her own status, it was difficult for anyone to study with her, but generally speaking, Cai Yan seemed to be able to answer as long as it was a purely academic question.

"What's the reason this time?" Chen Xi put aside Cai Yan's answer after a while, and asked instead.

"The Gan family in Moling was divided because of a problem. In order to prevent the family from being split, Gan Fen, the patriarch of the Gan family, sent the problem to me, hoping that I could give an answer." Cai Yan said with a little sleepiness.

Looking at the sleepy look on Cai Yan's face, Chen Xi couldn't help but feel a little strange. Cai Yan still pays attention to her appearance in front of people. This obvious sleepy look is unimaginable to Chen Xi. What's wrong with it? ?

"It's strange, why did I ask you?" Chen Xi asked puzzled.

"Because I know the most academic knowledge on the surface, and compared to some people, I seem to be more idle." Cai Yan said unhurriedly.

Chen Xi scratched his cheeks, he didn't know what to say, but that's right, on the bright side, it was indeed Cai Yan who stood at the top of the academic stuff, and the key to the inner library of the Zangshu Pavilion was hanging around Cai Yan's neck. And Cai Yan itself is equivalent to a collection of books.

It is said that if any tyrant marries, three generations will be able to transform into an aristocratic family. After that, relying on the large number of classics that Cai Yan brought with him, it is enough to pile up the entire family into a scholarly family.

However, unfortunately, Cai Yan has no idea of ​​marrying at all, Cai Yan alone is responsible for the Cai family's reputation, so if Cai Yan doesn't mention marrying outside, even if other aristocratic families are interested, there is nothing they can do.

"What's the problem?" Chen Xi scratched his cheek, and asked with some embarrassment, "Speaking of which, can't you solve it?"

Cai Yan's own aptitude is very good, and he also has spiritual talent and quasi-spiritual talent. With the feeding of Chen Xi's large number of classics, he is indeed very good at academics. It is said that the current social environment, unless it is a philosophical problem, is not a problem. There may be situations that make it hard for Cai Yan.

"The earth we stand on is round." Cai Yan said slowly.

"..." Chen Xi's eyebrows trembled when he heard the words, but he didn't speak, but Lu Xun was completely stunned and his mind was in chaos.

"Uh, did you ask this, or..." Chen Xi thought for a while, and decided to think about what was going on before answering.

Although in the Spring and Autumn Period both China and ancient Greece proposed that the ground under their feet was a ball, neither side proved it.

Later, during the Warring States period, Gan De and Shi Shen in the Central Plains deduced that the earth was a sphere from the formation of a lunar eclipse. At the same time, Aristotle in ancient Greece also deduced that the earth was a sphere based on this, but both sides thought they were mentally retarded. , How can the earth be a ball!

So both parties just mentioned this guess in their own classics, and then said nothing more, and the evidence is a lunar eclipse. From this aspect, the group of people in 500 years is really extraordinary. After all, a group of actual founders of civilization were born on both sides.

Later, it was Luo Xiahong of the Western Han Dynasty who really proposed that the earth is a ball, and he directly went to the Huntian theory, but Luo Xiahong couldn't really develop this theory. Although it was proposed, it was not recognized by the mainstream society at that time. .

Going down to Zhang Heng, it would be terrible. The theory of the earth and the sky, the armillary sphere, directly explained many astronomical phenomena in the earth-moon system and the solar system at that time.

However, Zhang Heng himself couldn't explain it. If the earth was a ball, why didn't he roll down? In addition, Zhang Heng's conditions at the time could not measure the area and circumference of the ball. There is no way to kill Gaitian completely.

As for the current period of the Three Kingdoms, the Huntian theory has already taken the upper hand, but there is a big problem with the Huntian theory, which is that it cannot explain the problem of the ball, because although the Huntian theory is popular, there are basically no one who is really sure that there is a ball under his feet. .

Now that Cai Yan is asking, judging from this tone, someone should have firm evidence.

"The Gan family, Moling Gan's family asked a question. Someone in their family moved a target on the sea, calculated the limit of the visible range, and calculated the circumference of the earth. They thought it was a ball under their feet!" Cai Yan was very helpless said, and then took out a stack of calculation methods and conclusions drawn from various verification results from his cuffs.

"What's the conclusion?" Chen Xi said with a big head. He already knew that some monsters in the Central Plains were difficult to deal with. Well, this wave really happened.

In fact, this cannot be blamed on Chen Xi. When they were on land, the ancients who were fixed in one place could hardly come to the conclusion that the earth is a ball even with the knowledge accumulated by several generations. As a result, last year, Zhou Yu sent a group of astronomy, astrology , People from Feng Shui and geomancy got on the boat and went south, and this group of people almost got into a fight on the boat because of the astrology.

Needless to say later, the Gan family was dissatisfied, the Chen family was unhappy, and the Wang family was also black-faced. In the end, this matter was exposed, but looking back, these three families returned home and directly started the whole family research mode, but the Gan family smashed it. The money was the most ruthless, and the method was chosen correctly. It only took half a year to get the result, and because of this result, the Gan family fought internally.

"The calculation of the circumference is based on the latest data calculated by Zhao Junqing. Gan Fen took Moling Gan's family to measure it at sea for two months, and finally confirmed that the ground under his feet is a ball, and the value will increase as he goes south. According to their calculations , the maximum circumference of the land under your feet is [-] kilometers in the latest unit." Cai Yan handed Chen Xi the calculation draft paper sent by Gan's family.

Chen Xi was silent. The difference between this data and the data in his impression is actually very small. It should be said that this family is worthy of doing this professionally.

Looking at the calculated data in his hand, Chen Xi admired it immensely, and it indicated a large amount of actual measurement data. In order to avoid mistakes, he even conducted several actual measurements at the same place. After excluding some unexpected data, he took the average value for calculation.

There are also several calculation methods, such as shadows in different areas at the same time and height, the visible distance of the sea horizon, and even such as asking the immortal to use a light spell that is almost like a laser, and then the ship stays away from the sea, and the straight ray is calculated at any time. As the height of the vessel rises away from the scale mark, the last data taken is the last data.

Naturally, the accuracy of the data calculated in this way is terribly high. By the way, in order to complete this test, the wealth accumulated by the Gan family over hundreds of years has evaporated by one-third. The cost of buying ships, manpower, and purchasing accurate clocks , buy colorless crystals and more.

　To be honest, there are a lot of ancient people who are against the sky. The cycle of some astronomical astrology is directly several generations in terms of the life span of people at that time, but they have been researched...
