As a star warlock, a third-level star warlock, Wang Linghe's personal work as a messenger is completely out of appreciation for Cheng Jinzhou, which in no way contains a responsible attitude towards society, the world, and mankind - the star warlock is too lazy to care about the affairs of the court, even if someone will die.

Although it was something he didn't care about, the message of three or two sentences shocked Mrs. Cheng into a sweat. The foundation of the family is in Shaonan, and if the imperial court blames it for this, the Cheng family will lose the most.

There was no need for Wang Linghe to elaborate, Mrs. Cheng had already made a decision in her heart and sent the star warlock away, so she dressed neatly, held a stick, and called the big butler over.

The big butler is a person who has been serving for 5o years, older than those second generations, and he is also full of white hair, neatly dressed, and at first glance, he looks like a retired old-fashioned knight master. Really speaking, the status of the Cheng family's chief butler is higher than that of the knight master.

His straight back was in stark contrast to the hunched second butler, and despite the slippery snow in the courtyard, he still walked with a standard square step in a standard long robe, and could hardly see any change from his usual days.

Old Mrs. Cheng's expression was majestic, and she said in a solemn tone: "You go to Cheng Feng to get two people, and tell the people below, whether it is yesterday or today, whether it is firewood, rice, oil and salt, or weddings, you are not allowed to say, you are not allowed to ask, you are not allowed to talk, who dares to chew a tongue, you will be killed immediately."

The tone and semantics are like the sunset after the rain, deeply pressing on the horizon.

The maid next to her was so excited that she almost dropped the towel in her hand to the ground, and her face was frightened.

"Ahh The chief butler also looks good on weekdays, but at this moment, he couldn't hide his surprise, and he hesitated slightly. The execution of people by aristocratic families has always been a gray area, and few people except the royal family say it openly. Generally speaking, it is usually the servant who cannot stand the dead, not the master who is determined to kill.

In a hurry, the old lady who was stationed in the military town with Cheng Wenzheng in the early years was well versed in three of them, she did not hesitate or stay at all, and continued to speak sharply to the surrounding Cheng family: "The order just now is also effective for you." No matter which one it is, be careful if you dare to talk nonsense. ”

The gathered are all the sons in law of the four branches of Qingyue Haraka, as long as they are restricted, the concubines have no right to speak at all.

Liu Qingshuang lived very close, and was also summoned, looked at her toes thoughtfully, and thought: In this way, it is not easy for the imperial court to know what happened to Shaonan City.

Everyone was submissive, and the old lady continued: "Cheng Feng, you take some people to the city wall and bring Jinzhou back." ”

Cheng Feng is the chief of the guard, he answered "yes" loudly, and ran out against the wind and snow, a standard soldier.

The snow was falling intermittently, sometimes it was snowflakes, sometimes it was snow particles, clumps of marshmallows, like marshmallows that had been left for a long time.

The snow that fell on the ground piled up in loose pieces, taking over the streets, taking over the gardens, taking over the roofs. Some of the young people tried to fight it, but eventually they all gave up, leaving it to stand like a wall in front of the door.

At this point, the only thing that will be thanked are the windows, their importance is maximized, the doors that can't be pushed open, and the peepholes that lack color.

A long night.

In order to let the homeless people survive the first 12 hours, so that they would not fall to death or take risks, the porridge shacks set up in the four cities have never stopped, and the rich nobles have also tried their best to gather bedding and cotton wool. By noon the next day, thousands of stones of grain had turned into energy to keep out the cold, most of which came from the trading platform.

It is no exaggeration to say that Cheng Jinzhou is using his credit to try to keep his father's official hat. Otherwise, let alone a riot, even if there are too many dead, when the officials take the public examination, a bad review is equivalent to ending his future.

Of course, it's worth the effort. Materials such as the beams of the collapsed house alone can make him pay for himself, and the rest is far from a problem.

The difference between being born into a rich family and being born into a family of extreme poverty is huge.

The victims of the disaster, who had returned to peace, began a new life, and the officials of the state government quietly took over the work of the government, working like real managers, but everyone had different thoughts in their heads. Few people know exactly what happened to her, and this is the main reason why the prefect still hasn't received any official reprimand.

Also returning to calm is the long-lost Sun Father, who has just ended his chaotic relationship with several other planets, making him appear a little weak, and the idle sunlight shining on the thick snow has no effect.

While the nobles were busy in the fiefdom, Liu Kuang quietly came to the door.

The status of the Star Warlock is extremely high, far from being comparable to the local nobles, let alone Cheng Jinzhou.

The latter felt strange in his heart, but he took advantage of the servants to serve tea and pour water, and he did a good job of covering it up.

Liu Kuang always paid attention to Cheng Jinzhou's expression, but it was Xiang Xin, an apprentice of the Star Warlock, who spoke first, and she almost just sat down and said, "Mr. Cheng, I still have two questions I want to ask you. ”

"Oh?" Cheng Jinzhou looked at Liu Kuang strangely. When he was studying for a doctorate, if a doctoral student asked another supervisor a question of the same major in front of his supervisor, it was tantamount to a slap in the face, and the consequences were equivalent to sleeping with the boss's wife, and the end was second only to sleeping with the boss's woman.

Liu Kuang smiled very kindly, took two sips of tea, and then waved his hand and said: "Over the years, I have mainly studied coordinates, although the Euclidean geometry you have learned, although it is similar to the previous generation, it is different, and the subtleties are for you to explain, if you don't mind, let the old man listen to it." ”

It was the first time he called himself an old man in front of Cheng Jinzhou. This word is actually a kind of intimacy among the nobles of the Great Xia Dynasty, not every old man is qualified to call himself an old man, and not every old man with status will call himself an old man in front of his juniors, it is more used in front of students and juniors.

If it were an ordinary local nobleman's child, he might be grateful at this moment.

However, Cheng Jinzhou only disguised it with a smile that he barely pretended, and even said, "Don't dare to be, don't dare to be." ”

Xiang Xin wrinkled his nose, took out a thick stack of drafts from his arms, spread them on the table, and said seriously: "It's about drawing, I heard Mr. Wu say, you once said that 17-sided shapes can't be made with rulers?" ”

"You've learned it all?" Cheng Jinzhou was quite surprised. Drawing a 17-sided shape itself is not really meaningful, but it is more difficult than a paper-cutting method. But if we know the foundations of Euclidean geometry, it is important that the most fundamental geometry is more advanced than the Pythagorean mathematics, and that the axiomatic structure is correct, and if you admit that its assumptions are correct and the derivation process is correct, then the answer must be correct.

This kind of thinking has continued to influence the world for more than 2ooo years.

Because of this, Euclidean-based geometry required a high degree of premise or problem, and for early mathematicians, their propositions were either directly derived from the five axioms of the Geometry Primitives, or they based their problems on realistic geometry.

The so-called realistic geometry is the geometry that can be drawn with a ruler and a ruler - the universality of the ruler is the main reason why mathematicians recognize it.

Therefore, if people can make 17 sides with a ruler, then they have one more condition for all relevant problems, and if not, many problems will have to wait for other mathematical means to be understood.

Of course, just like a famous mathematical problem, the lingering process of studying a regular seventeen-sided shape will always bring mathematicians countless new discoveries, and its value may even be higher than the problem itself.

In Cheng Jinzhou's view, when Xiang Xin thought of the problem of 17 sides, it showed that she had reached the world's first-class level. In particular, through the rigor of Euclidean geometry, she took a complete shortcut.

Cheng Jinzhou thought deeply for a while, and then looked at Xiang Xin, and suddenly felt like a master who was about to die in the novel, and the bald little beauty in front of him was the protagonist, waiting for him to use the empowerment ** to pass on his skills......

"Mr. Cheng?" Xiang Xin called in a low voice.

"Oh, haha." Cheng Jinzhou seemed to come back to his senses, and smiled embarrassedly: "I just said that no one present can draw a 17-sided shape." ”

In fact, he also said that no one could draw it, and now it deserves to be blown away by the wind.

Liu Kuang groaned: "The old man has been thinking about it for a few days, but he has no clue. I asked a few friends and asked them to help them check in the Star Warlock Association, but to no avail. Can you draw it? ”

Listening to what he said in the process of being so troublesome, Cheng Jinzhou was extremely big, and he couldn't tell the truth. His head shook quickly, "I can't draw it either." ”

The main steps of the 17-sided ruler and compass drawing are only 1o steps, and any third-grade child who can use a ruler and compass can complete it. But why is it such a 1o step, is the really valuable place, Gauss used a book to explain the situation, how can he remember it all in his head.

Xiang Xin said with a disappointed expression: "Then do you think that the 17-sided shape can be drawn?" ”

This is actually the standard problem of the regular 17-sided shape, which can be drawn to show that the regular 17-sided ruler is drawn and stored in zài, and if it cannot be drawn, it is not saved zài, and how it is drawn, but not the main point of concern.

Cheng Jinzhou pondered for a moment, forcibly peeked at Liu Kuang's **, and said carefully: "It should be able to be drawn." ”

"That's a big problem." Liu Kuangdeng narrowed his eyes, put the teacup on the corner of the table and said, "Can you write an article on this and report it to the association as a result?" There will be a lot of people who care. ”

A lot of people care about it, which means a lot of association contributions, the most important trading unit for the astral warlocks.

Cheng Jinzhou's eyelids jumped, he was quite moved, but he said: "I'm afraid this will be studied for a long time, I just read books by myself, and I haven't studied systematically." ”

He said it softly, and he was also telling the truth. The 17-sided drawing method is something that appeared later than analytic geometry, and it won't be revealed if he is killed, and he really can't write the process. Except for gentlemen who study the history of mathematics, and professionals who are highly accomplished in related fields, who in the 21st century will have nothing to study such an ancient thing, and then change to a standard mathematics professor, and the result will still be the same.

"Star warlocks are geniuses, and geniuses should have their own paths." Liu Kuang showed a trace of regret and said: "You also have to hurry up." If you have any questions, you can come to me, you have a chance to become a one-star warlock. ”

Cheng Jinzhou immediately expressed his gratitude. A one-star warlock can be described as a symbol of status, and the difficulty and rarity can be compared to the academician in the previous life, and the status is still much higher. As for the two-star and three-star warlocks, it shows that the academicians are also high and low.

Liu Kuang may not be a pure mathematician, nor is he the cutting-edge figure of the ivory tower as Cheng Jinzhou imagined, but compared with those full political animals, he has become pure and kind.

People are always like this, they come and go.
