Whether it is astronomy, geography, or climate, there is one thing that cannot be avoided in the end, which is mathematics.

If there is any secret book in the real world that can be invincible, it is mathematics. If you learn this thing, you can really defeat the world by sword. The problem is that the secret book of this thing is everywhere. The masters of the math path want to spread their knowledge wildly in the world, hoping that later generations can enter their own methods, and there is no intention of cherishing them.

But most of the time, people who get secrets just look at it and find ways to deal with it. Those who can get started can’t see the end. Most of them switch to finance and make some money. There are only a handful of people who can get to the end with secrets. In every era, there are only a handful of people who can get to the end with the secrets.

Of course, this is a blind spot for normal people. For those who really need to study and study certain disciplines, mathematics is a blind spot. The Gan family and the Shi family can calculate the range of gravity acceleration by vacuum styling, and rely on the inverse deduction of data to Kepler's three laws. The level of mathematics alone is actually not weak.

At least compared with the average level of this era, it is already at the top of the era, and those who go up are basically mathematicians who are included in history books.

However, when I heard Chen Xi say it was mathematical calculation, my face turned green. It was not that Gan Shi and the two families were not good, but that this thing was really too difficult to calculate. You should know that later generations of calculations were all used in supercomputers. Gan Shi and the two families now realized the precession, the Zhang Ding and the extreme movement, and wanted to rely on existing data to accurately calculate and predict...

"Well, lend me five brothers Zhao, we can calculate it next year." Gan Bao said with a little depression after a while.

"Is it so exaggerated?" Li You frowned and looked at Gan Bao and Shi Tao. He actually didn't understand what Chen Xi talked with these two people at all. At most, he relied on asking his own son to understand more about what prematureness is. As for other things, what is that.

But as that goes, Li You still respects the Gan and Shi families more. After all, these two families do not cause trouble, and they have no money to deceive others into making some resonance with the gods and humans, and then divide some money to continue to do their own work. They are already considered to be an extremely reliable family among the aristocratic families.

What's more, if you do a better job of the Astronomy Calendar and make 5% to 10% more grain, it is also countless living people, so Li You is still willing to give some respect to such a family that really does things.

"The five are conservative. After looking through the records from ancient times, we suspect that this thing is regular, but the whole picture of this thing cannot be seen in the human life cycle." Shi Tao said with a little tiredness. This is not a joke, but a judgment they made after comparing the declining angle of the shifting star palace for thousands of years.

Chen Xi couldn't help laughing when she heard this. The precession actually led to a bunch of fun things. Chen Xi estimated that the cycle that Shi Tao mentioned should be the celestial ball moving around the yellow pole. This cycle is about 20,000 years. As for the more realistic things, it is probably the vernal equinox that moves westward, and the displacement of the star map has been accumulating, and basically it has to be changed every fifty years.

If the Ganshi and the two families used the star maps to compare during the Shang anniversary, when they were sure that there was no problem with the star map, they should have realized that the coordinate system based on the concept of the equator is also changing, and this change is the embodiment of the precession.

"It's hard to calculate?" Li You looked at Chen Xi and asked Chen Xi. He asked Chen Xi directly about mathematical problems he didn't know. This is the experience accumulated by Li You.

"Yes, it is quite difficult to calculate this in the current situation of incomplete data, and the two heads of the family should have some doubts about the notes left by their ancestors." Chen Xi looked at Gan Bao and Shi Tao and said with a smile. The two did not deny it and nodded.

The problem is here. When the overall image cannot be fully observed, mathematical calculations must at least have a part of accurate original data. But what about the original data obtained by the Gan family and the Shi family now? It cannot be said that they cannot trust their ancestors completely, but they cannot determine which ones are available and which ones are not available. Since this is the case, it is better to directly test them.

"Then let's take a test. I can provide funds and let the Ganshi family borrow Xu Gonghe for a period of time every year." Chen Xi thought for a while and said.

It is impossible for Zhao Shuang to borrow it. It is Sun Qian’s private computer, and Guo Kai is not a mathematics department at all. Unless the Gan and Shi families conceal the map and Guo Kai directly confirms the authenticity, Guo Kai is actually meaningless in this regard, so the only one who can use it is Xu Yue.

Li You gave Chen Xi a fierce look. Xu Yue was the best tool guy in his hands!

"This requires continuous investment, and it may not work in a short period of time." Although it is a fraud, Gan Bao still has to say the ugly words.

"It's okay, this kind of thing is built bit by bit. Just remember to keep all the data and information in detail." Chen Xi said with a plain expression. This thing is very important and is related to whether the research can continue in the future.

"We have also considered this aspect." Shi Tao nodded and said, "We have connected with the Yuan family. The Yuan family is implementing a very strange management method. We think there is some meaning to learn from, so we are also preparing to promote it."

"What management method?" Chen Xi first took it out and made it from a special paper made by a special papermaking place, and then wrote the corresponding entries on it, then took out the seal of Ziye Township Hou and stamped it, and then stamped it with his own private seal, Chang'an Money House's spare seal, and added the number. He handed it to Shi Tao and asked.

Currently, Chen Xi is making the large amount of redemption tickets by himself. After all, there are not many pieces a year, and no one will use such a large amount, so each piece is stamped by Chen Xi.

"It was said that it was suggested by a new civil official from the Yuan family. The clerks were arranged for local villages and villages, so that the clerks could record what happened every day, without asking for quantity, just one note every day, nor the quality was required. However, for outsiders and travelers, special events must be recorded, even a word can be done." Shi Tao thought for a while and said, this was what the brother who ran back from the Yuan family said.

Chen Xi was silent for a while when he heard this, he understood after a little thought that this thing was done by Cyprian.

Historically, after European public church absorbed Cyprian, it was officially becoming regularized. Many rules were created by Cyprian. Chen Xi was not sure about the initial reason for requiring priests from churches in various places to write diaries, but this operation solved many problems.

Education, learning, inheritance and other things are accumulated little by little. Then when there are more churches and priests, it is easier to manage such a thing. After all, if a big event happens, you don’t record it, and the surrounding churches will also record it. If you check and compare it, you will naturally know who is doing it.

Of course, if you have the ability to block the mouths of several churches around you, it is difficult to block the mouths of all churches. After all, if you block too much, there will be more people who know that you are gaging, so there will naturally be people who will record it easily.

This is also the reason why Europe has not had an orthodox historian for a long time after the third century, but it still has enough local historical materials for reference. To put it bluntly, these priests record what happened in their own place in a book-like manner. Although most of them are trivial matters and do not involve major events in the local area at most, there are still a few words to mention, but there are many churches, and there are always around the incident.

To be honest, Chen Xi didn't quite understand the reason why Cyprian asked these priests to write diaries. It was not realistic to say that he had seen so far in the third century, but this matter was undoubtedly a wonderful step.

It's just not suitable for the Central Plains. The Central Plains have always been official history and will not allow others to do whatever they want. Even if they write diaries, some things cannot be written. This is why the historical history in China is very complete and the details of ancient people's lives are missing.

On the contrary, because of Cyprian's gameplay, many priests have no diary in their diary today, so they just write about the situation of the people around them. So in the Middle Ages, the poor people ate what they ate, how they made, how much wood slag, bran, etc. They will all mention the above. Anyway, what the above requires can't withstand the above request. Let's just slap and make perfunctory. Today, I will give a tutorial on making baguettes that are enough to kill people. Bar.

These things were undoubtedly perfunctory in the priests recorded at that time, and these things that were not of any significance, were just written in casually, but hundreds of years later, these things became important materials for studying the real situation of that year.

This kind of material is actually relatively small in the Central Plains. Since the First Emperor, the perspectives of all dynasties have been on how the rulers maintain their rule. There is actually very little attention to the ruled. The recorded information is mainly on the rise and fall of the country. It rarely focuses on the ruled individuals. At most, some records of individuals can be seen in private letters.

However, the number of such private letters is very rare compared to the huge ruling individuals, so that the descendants of the Central Plains can clearly recreate the prosperity of their own prosperous dynasty, but it is difficult to build the lives of the people of the same era from the level of detail.

What they eat, what they play, how they spend time, and how they spend time, these ordinary people’s things were basically a desert before the novel was formed.

That's right, it is the most despised by people. It is considered a lower-ranking Ming and Qing novel in literary history. In the end, it constructed a living, real ecological reality of the Ming and Qing dynasties, allowing people to clearly understand how the people of that era lived.

Even if it is not historical materials, it is at least a reference, so that most people in later generations can know how ordinary people in the Ming and Qing dynasties lived when they want to understand it.

As for moving forward, it is a very professional field. The information of big people is very detailed, but the information of ordinary people is too small, so few that they can only search through history books.

Cyprian's gameplay seems to be just for easy management, but if you stand in the lower reaches of the long river of history and think about it carefully, you will realize that these materials passed down like flowing accounts represent the lives of many ordinary people.

Every word of historical materials for big people needs to be considered, but recording the diary of small people and filling them out casually. Even if it is perfunctory to deal with it, what remains is the truth of the parties involved.

"This plan is pretty good." Zhuge Liang said in a serious tone after hearing what Shi Tao said.

"Oh, then do you mean?" Chen Xi asked with some curiosity.

"Let the aristocratic families in Central Asia write as well and submit one every year." Zhuge Liang said with a smile.

"In fact, this was written by them, but they were not yet formed and the requirements were not strict. In fact, the task of making a book of the inner history is to collect this diary, then compare the records, and then find the wrong places in the inner world to hold them accountable." Chen Xi said casually, "When the Zhou emperor was still authoritative, the Central Plains was also being promoted, but it was just for the princes and kings."

"Oh oh oh, no wonder I feel so familiar." Gan Bao reacted instantly when he heard this. He said, and he said why he looked so familiar, and his ancestors had already played with it.

"It looks familiar because my ancestors have played it, but I can't react because the First Emperor burned all the diaries of several other families." Fa Zheng said quietly. He also reacted and quickly understood why Chen Xi didn't follow up when he said this. The Central Plains was not suitable for this way of playing.

"But this kind of gameplay is suitable for the Yuan family, which can be considered mutual restraint and strengthened management." Chen Xi turned a blind eye to Fa Zheng's eyes. Even if the Zhongyuan plays like this, it will be useless when it is unified in the end. This approach requires another team, and Zhongyuan cannot do another one, and Chen Xi will not allow it, so he can only watch it.

"Forget it, let's not mention this, everyone has their own ways of playing. Speaking of which, the grand ceremony is coming soon this year. Who will the Yuan family send here?" Chen Xi didn't want to bother about this matter and asked naturally.

"I don't know, we have not had in-depth exchanges with the Yuan family. These news were brought back by my clan brother." Shi Tao shook his head and said, "But if there is a private grudge, even if Duke Zhong Guo can't come, he will have to have a heavyweight figure. No matter how bad it is, he must come in person."

Yuan Tan was conferred the title of Duke Zhong, but the current titles of the Han Dynasty are basically clearly divided. According to the internal and external conditions, the highest internal title is Lihou, while the external title is Lihou, but the external title is Lihou was not directly promoted, but was granted a fief. The complete set of legislative power and military and political control are taken at once, which is considered a complete marquis. The Duke was directly moved to the princes, so generally, the Wen family was the princess and Stina was the concubine.

As for the other women in Yuan Tan's inner courtyard, none of them had formal titles, which means they had no titles. They could only be said to be maids with some status.

"If I remember correctly, Princess Zhong gave birth to a child. The banquet has not been held yet. The edict for the enthronement has been prepared, but the Yuan family will let it be suppressed for five years first." Zhuge Liang frowned and said after hearing this.

Yuan Tan would definitely not come to the Grand Court, and Wen had just given birth to a child, so he was unlikely to come. He couldn't let his concubine Stina come over. It's not impossible. No one could say anything about Stena's identity and strength. The problem is how big the Yuan family has to let Stena come over alone.

"The three Yuan family, the remaining two are also sick this year." Fa Zheng added, which means that the Yuan family must send people to Chang'an to attend the court meeting next. After Yuan Da's death, the two brothers Yuan Sui were in good health. After all, their fate was almost here, and those who were as strong as Zhao Qi were the minority.

"It should be impossible for Zhongda to be. Xu Zi went to Rome. In this case, would it be Xun Youruo?" Chen Xi thought for a while and said.

After all, it was the grand dynasty meeting at the beginning of the eleventh year of Yuanfeng. No matter how many things the major families have, they will participate. The development over the past decade has made the major families clearly realize that it is better to hold their thighs than to rely on themselves, and Chen Xi's thighs are really thick and powerful.

Therefore, the major families will not miss the grand dynasty meeting at the beginning of next year. The person who comes either the head of the family or the head of the company who can make a decision in one sentence, and the current situation of the Yuan family.

"Well, probably, it happened to let me meet Xun Youruo." Fa Zheng raised his eyebrows when he heard this. All the people from the Xun family, Fa Zheng could see, but Xun Chen could not sit down and talk. Fa Zheng was also interested in seeing this guy who claimed to be able to analyze his opponent's thinking.

"Maybe he will bring Cyprian to you." Chen Xi said with a smile. To be honest, he wanted to meet Cyprian. After all, in terms of its impact on world history, even Zhuge Liang was still a certain distance from Cyprian. In terms of ability, Cyprian could also be worthy of the heavens.

In addition, Sima Yi also wrote to Chen Xi to complain about Cyprian, and Chen Xi really wanted to meet the guy standing at the top of countless wise men in this era.

"Are you interested in that guy?" Fa Zheng felt a little different from Chen Xi's tone, "That guy is amazing?"

"It's amazing. If you really want to say it, it can be considered a celestial being." Chen Xi thought about it and gave a positive answer.

"It's rare that you have such a high evaluation. I want to know about it." Li You glanced at Zhuge Liang, and then said with a bit of contempt.

"This time, it's really a celestial being." Chen Xi saw Li You's expression and said very seriously, "At least in some aspects, even Kong Ming will find it difficult to surpass the other party. The true pride of the times and the celestial beings are just not sure whether they will come at the end of the year."

"Ah!" Cyprian rubbed his nose and then raised his own issue in the Senate, "The unrest caused by lack of food should be put aside first. This level of unrest is nothing at all. At present, the most important thing is to solve Odin in Northern Europe as soon as possible. Otherwise, when the local unrest expands, Odin takes advantage of the chaos to go south, and with the inside and outside, Rome is overturned in front of him."
