Narrow non-Euclidean geometry only slightly changes the fifth axiom of Euclidean geometry, and then deduces conclusions and propositions that are completely different from Euclidean geometry.

It was originally completed by Lobachevsky. Strictly speaking, this Russian scientist did not perfectly prove the correctness of his proposition. He only proved that his non-Euclidean geometry, after countless deductions and derivation, had no logical contradiction with Euclidean geometry.

This is at least 99% proof of the correctness of Lobachevsky's geometry, but it is not 100% certain.

Because of this, this professor who made great contributions and created a new field of mathematics was also as unlucky as Mendel. Until his death, his arguments were not fully recognized by the academic community, but instead received various criticisms. All kinds of suppression and persecution, as people praise him, he is the "Copernicus of geometry" - if the story of the three musketeers is used as a benchmark for happiness, then Copernicus, Mendel, and Roman Bachevsky is a typical example of failure in life.

Of course, they left their mark in history.

It is not easy to complete Lobachevsky's work based on the standards of the world of astrologers, generally from the 16th to 17th centuries - in fact, the mathematician who can do this is definitely the elite of mankind, Cheng Jinzhou It takes all the energy and previous accumulation of knowledge to read Xiang Xin's article.

The paper is quite jerky and the proof is quite insufficient.

Xiang Xin himself knew this, and said timidly: "What do you think? Is it too bold?"

Cheng Jinzhou laughed, pondered for a moment, and said, "Actually... it's pretty good."

Lu Xu breathed out, almost sucking the table over, and said angrily: "Mr. Cheng, you can't tell lies."

He was Xiang Xin's uncle, but he couldn't tolerate Xiang Xin going to his head, and he was praised by Cheng Jinzhou.

After being with Cheng Jinzhou for a long time, he also understood its power.

Xiang Xin's forehead lit up with laughter, and the anxiety in his heart suddenly disappeared, and he said happily: "I have always been worried that the argument was not enough."

Cheng Jinzhou thought to himself: If it were a normal mathematics paper, the argument would not be enough. Back then, Lao Luo was almost bullied to death because of this. However, because of the name of non-Euclidean geometry, he lightly marked it with two strokes of red and said: "Perfect it again."

Xiang Xin's eyes immediately lit up.

In addition to hoping to be recognized, what she wants most is Cheng Jinzhou's guidance.

Xiang Xin carefully re-read the deduction part of the paper. After a moment, she suddenly asked, "Can I show it to the teacher?"

"Teacher? Oh, Warlock Liu Kuangxing?"

"Um...yes." Xiang Xin was a little embarrassed because due to a series of events, the relationship between Warlock Liu Kuangxing and Cheng Jinzhou was not as harmonious as expected. To a certain extent, the reason why Xiang Xin was able to stay and study near Cheng Jinzhou and his team was largely due to the relationship between the two parties.

Cheng Jinzhou pondered for a moment and then said: "I insist on doing my own research. That's fine."

The last sentence is a response to the previous one. Non-Euclidean geometry is a very important subject that can reflect intelligence, but there is no need to have any expectations as to what it can develop into now.

Furthermore, for now, Xiang Xin’s value is greater than non-Euclidean geometry itself.

The latter should be a testament to her.

However, in Xiang Xin's view, Cheng Jinzhou's generosity was really surprising, and he was naturally overjoyed.

Jiang Huang also nodded secretly.

Cheng Jinzhou made a shrug and slowly floated up, flying towards the inner hall.

Even when flying low, he always had a smile on his face. Compared with the convenient public transportation in modern society, he prefers to fly on foot...

Flying is truly the most desirable thing for human beings.

One day, when the urban manned vehicles go up to the sky and into the earth, with nowhere to hide, human beings will miss and need to walk on their own. At that time, perhaps it will be the time for genetic engineering to shine.

While Cheng Jinzhou was thinking wildly, his body faithfully floated back to the room. Shi Mo followed closely behind him and returned with the account book. The excitement on his face was almost weird.

Contrary to what everyone imagined, Cheng Jinzhou only invested one-fifth of his contribution points this time, just over 300. Even so, 2.6 million taels of silver was terrifying.

"Third brother, if I put in a few hundred more contribution points, I'm afraid I could have tens of millions of taels of silver now, and I'd be a father." Shi Mo's tongue was uncontrollable.

Cheng Jinzhou waved his hand. People in this era have not yet realized the power of rules and standards.

After looking at the detailed account books, he said, "Are you ready to give the silver coins to the star warlocks?"

"All the flight tickets sent by the merchants have been checked..."

"This won't work." Cheng Jinzhou immediately interrupted Shi Mo. The most famous term created by the modern check system is "blank check", not to mention Daxia's flying check system. How much money is in the treasury is really something that even the emperor and I cannot decide.

Before the trade fair, he did not consider the issue of flight tickets. He expected that it would be easy to exchange millions of taels of silver. Who would dare to default on the Star Warlock's flight tickets?

But if the number is too large, reality is the biggest enemy.

Shi Mo also knew it and said hesitantly: "15.87 million taels of silver..."

"I know there are a lot of them, and it is convenient for the merchants to pay for the flight tickets, but giving the flight tickets directly to the Star Warlocks, or waiting for the three envoys to exchange them, is a suicide." Cheng Jinzhou stood up and wrote a brief letter. He then handed the letter to Shi Mo and said: "You go to my dad and you have to exchange all the silver today."

"I'm afraid the vassal treasury doesn't have so much cash." Shi Mo's face turned green. When I was in Shaonan, 100 taels of silver was a huge amount of money in Hengxing Township. In the prosperous capital city, 1,000 taels of silver would be enough for people to brag about for two months, not to mention adding 10,000 taels of silver at the end. How many carriages would be needed to pull it?

"This is why we need to use credit currency." Cheng Jinzhou muttered to himself and said with a rather evil smile: "The daily expenses of the Third Secretary are naturally not enough, but if you add military expenses, it will definitely be enough. . Or, let His Majesty’s inner treasury provide the funds.”

He could only imagine such a thing as making the emperor's coffers bleed.

Shi Mo didn't understand why his master did this, so he took the letter and left hesitantly.

An uproar spread from then on.

If the trade fair held by Cheng Jinzhou was only limited to the upper class, his new demands would inevitably involve the imperial court.

Before that, both the political leaders and the nobles and royal families tried their best to avoid getting involved in the consumption wave of the Star Warlocks.

But now, 15 million taels of silver have definitely set off a wave of runs.

The 1850 association contribution points are only the total contribution points of two entry-level three-star warlocks. He has used practical actions to prove the meaning of the high-level star warlocks' wealth.

There was chaos in the political hall.

Cheng Jinzhou's second uncle, Cheng Yunxiang, seemed to be the backbone of the chaos. He was dealing with mudslides in floods and was obsessed with getting things done.

He is a standard official, or a rational politician. Compared with the majesty of the Emperor, he prefers to favor his nephew. In Chinese history, those officials who opposed the emperor were no more unlucky than those who obeyed. many.

With Cheng Yunxiang taking the lead, Master Cheng Yun'an resolutely lined up behind.

As a scholar who pays attention to the golden mean, Cheng Yunxiang has an early supranational concept - according to his understanding, flying notes are money that people deposit in the imperial treasury, and the notes are proof. If someone wants to withdraw the money, they will naturally withdraw it. Nothing more than normal.

The third- and fourth-rank officials in the capital, whether they were big or small, were really tough, but the first-rank officials were speechless.

The Minister of the Ministry of Personnel said that "close relatives should avoid suspicion", but Cheng Yun'an said "the world is dedicated to the public" and rejected it.

The only person who can express ordinary excuses so righteously is Mr. Cheng Yun'an, probably because he really believes it.

"15 million taels." Mr. Liu, the Third Chief of Staff, tapped on the table. He is the clan uncle of Liu Bin's transfer envoy. He has been the God of Wealth for more than five years and can be said to be the person who knows the economic situation of Daxia best.

Although the amount of money on the flight tickets has long been stored in the vassal treasury and is theoretically not allowed to be used, based on the government's judgment and credibility, this kind of permanent commitment is always meaningless.

Several ministers and bachelors looked at him. After a long time, the chief minister opened his eyes wide and said, "Master Liu, the emperor is still waiting for our return."

"The capital must leave at least 1 million taels of silver for emergencies. If so..." The third envoy said and then stopped.

Li Shaolin immediately raised his eyebrows and said: "Mr. Liu, everyone present is an important official of the imperial court. How much money is in the treasury, there is no harm in talking about it."

This is also an interesting part of Daxia's finances. Only the three secretaries and the emperor know how much money the entire country has. Occasionally, when the civil servant group has greater power or under special circumstances, the chief minister can know about it.

Therefore, rather than saying that the Minister of Rites was angry because of the urgent time, it is better to say that it was the curiosity of the important officials of the imperial court.

Lord Liu looked at brothers Cheng Yunxiang and Cheng Yun'an, and knew that he could not drive them out. He shook his head and said with cupped hands: "Sir, all the money in the treasury is useful. If you want to withdraw it, you can take out 13 million taels. "

Lord Chief Assistant sat down with relief and said with a smile: "There are 2 million taels left, which is easy and tight."

Cheng Yun'an was thinking about another thing. He scratched his head and asked, "These flight tickets are originally stored in the common people's treasury. Why are they 3 million taels short?"

The third envoy was stunned for a moment, and then he also sat up, laughed twice and said: "Master Cheng, how can we talk about this? The imperial court has expenses every day, the money is put into the treasury, and the accounts are left. That’s all. Is it possible that if you deposit a bunch of money, you want us to find the bunch of money and return it to you?”

Cheng Yunxiang grabbed Cheng Yun'an who still wanted to speak, and smoothed things over: "Several adults are discussing, I and I will just listen."

The first assistant narrowed his eyes and said nothing. He is a standard first-rank official, waiting to be crowned a marquis. If it were not for the star warlock, there would be no room for two mid-level officials to attend the ceremony.

After deliberately being silent for half a minute, the First Assistant said again: "Sir Liu, where will the remaining 3 million taels of silver be allocated from?"

"Mo Ruo... inner treasury?" The third secretariat thought exactly the same as Cheng Jinzhou. Daxia's finances were divided into two parts. The national property and the emperor's small treasury were mixed together. At first, this was a small trick to deal with the centralization of power by the nobles. Later, it became part of military preparations and continues to this day.

The Chief Assistant was about to nod when Li Shaolin suddenly said: "Sir, have you forgotten?"

"Oh...oh." The chief assistant's expression changed twice, and he suddenly fell silent.

Cheng Yunxiang remained silent, his expression similarly twisted with curiosity.

"Then, let's transfer 3 million taels of silver from Hexi." The third commander suddenly came up with an idea.

Hexi is where Mr. Liu Bin, the transfer envoy, is.

"That's very good." The chief minister obviously also thought of it, and quickly agreed, and started drafting the seal. At the same time, he said to the two Cheng brothers with a half-smile: "It's just tens of millions of taels of silver, just give us a few This bad old man is so busy that he is so ashamed."

"Sir, don't worry about it." Cheng Yunan took the lead and said: "As long as the taxes paid by the people are used properly and the silver in the vassal treasury is not misappropriated, things will go smoothly. I heard that there will be a new trade fair next month. It’s fine if everyone uses new tickets, but if they use old tickets, I’m afraid the adults will be busy for a while.”

After saying that, Father Cheng threw off his clothes and left.

Cheng Yunxiang didn't expect that his third brother, who usually didn't like to talk, would speak so sharply that he didn't know how to round it up for a while.

The princes of the political affairs hall looked as if they were unharmed, and their hearts were racing with oars again.

Beyond the word count: I would like to thank the book friends who have been able to support me until now. I feel ashamed that there are so many readers who still read the weekly. Special thanks to the "Huayan" book friend for his encouragement, and strive to "be a person who races against himself."
