Chapter 46 The Parallel Axiom
A good college student must first learn to grasp the key points.

Only by grasping the key points can we use less words and write more content on the note. Only with more content can we get a higher score-a life that is out of 60 points is out of vulgar interest Life, such a life, is a pure copying career.

Cheng Jinzhou is a pure plagiarist, but even in his busiest plagiarism school year, he has never speculated so many things, especially when he cannot print or copy.

The three-character classics are basically not tested, but apart from "Zhu Lue", there are three other scriptures that may be involved. The content is not too much, but for a student who wants to take the imperial examination, no matter how small the score is, he cannot give up.

Even in the township examination, if Ce Lun made mistakes in the previous two questions, he would definitely not pass.

Of course, the most important thing is strategy theory, which is like a college entrance examination composition. Whether there are tricks or routines is certain, but if you want to get a high score, you must either be more imaginative, or be more rigorous—no matter what What kind, asking Cheng Jinzhou to do it himself, is really harder than a pheasant killing a tiger.

For the current plan, in addition to copying more things recorded in the township examination, Cheng Jinzhou also went to private schools every day to ask the teacher how to piece together the essays.Just like before time-traveling, the most diligent time to go to class is always before the exam.

The professors in the Cheng family private school are indeed quite talented, but using other people's chapters to piece together an article and pass the rural examination, not to mention the difficulty, some well-known teachers don't bother to care about it. It added a bit of difficulty to Cheng Jinzhou's plan.

In fact, this means that you were born in a rich family. If you live in an ordinary peasant household, let alone spend a year's money and food to buy tens of thousands of words of books to read. Family background, low production efficiency, doomed not everyone can enjoy all the rights.

After a week like this, Cheng Jinzhou was unavoidably tired to death, and even the few professors whom he frequently asked for advice hid whenever they could.So, Xiao Cheng began to harass the customer service 010 again: "Can't you let me scan these pages in advance?"

"No."

"One?"

"No."

"How many similar books are there?"

"No."

"Then upgrade to Star Alliance level 4, or the corresponding authority?"

"You need to reach 1000 Covenant points."

This harassment taught Cheng Jinzhou a new truth. Customer service is like a toilet plug. It always hangs in front of your eyes when you don't need it, and it doesn't work when you need it...

……

Apart from copying and wrangling, the most tiring thing is practicing calligraphy.In the imperial examination, without a good handwriting, it is absolutely shameful. Although as a child of a family, Cheng Jinzhou's imperial examination path must be much wider, but if the writing is too bad, it is really unjustifiable.

To be honest, Cheng Jinzhou can be regarded as putting all his heart and soul into the imperial examinations, astrology, etc., and he didn't even study at all.

But if he doesn't learn, it doesn't mean that other people don't learn.

Xiang Xin is one of the fanatics.

Ever since Cheng Jinzhou made a very representative scale in front of her, the attitude of this bald girl has completely changed - this kind of change is full of utilitarianism in Cheng Jinzhou's eyes, but in the eyes of others, it is a small The girl strictly abides by the instructions of a capable person as a teacher.

Xiang Xin does not come to see Cheng Jinzhou every day, but every three to five days, she will come to see this "little teacher" who is not even a star warlock with new questions, and then bring a bunch of ambiguous answers , Continue to study hard until you know you have enough questions.

Of course, the main reason why Cheng Jinzhou didn't drive her away completely was that she knew how to bring some gifts every time she came to see him. In addition to some valuable gadgets, she would also give many things that Cheng Jinzhou needed, such as gifts from other places. Provincial Examination Transcript Booklet, etc...

In comparison, Wu Zong and the other astro-warlocks were half a beat behind.They also asked questions, but their attitudes were still humble, but they didn't notice that Cheng Jinzhou was not only a comrade who pursued spiritual pleasure, he also had considerable requirements for material things.

Therefore, there is always a reason for success. Even if an opportunity presented itself to Wu Zong, he didn't seize it right away.After two or three weeks passed, when he discovered that Xiang Xin's gifts had evolved from jade to antiques, and from antiques to cash, his savings were no longer enough to keep up with Cheng Jinzhou's pace.

Astrology is indeed a very lucrative profession. Even though Xiang Xin has just been promoted to a first-level astronomy, she can still spend dozens of taels of silver for "experiment fees" each time, while Wu Zong is much poorer. With the Cheng family's salary for research, the hundreds of taels of silver he worked hard to save soon went into Cheng Jinzhou's pocket-he is a low-level person, and he often asks to see Cheng Jinzhou, but it is far from enough to say how much he understands. Far inferior to Xiang Xin.

As for the other astrologists, let alone, as long as Cheng Jinzhou kept a secret, their advanced level was not enough.

In the eyes of a group of ordinary people, the incomparably noble star warlocks are like nine-rate actors with high self-esteem before they are recognized by their ranks. They want to become stars but suffer from pain. Those who can torture them use plastic surgery and sleeping pills to solve their problems.It's a pity that the gap in intelligence cannot be made up with plastic surgery.

……

Time is like a rabbit being chased by a dog, passing quickly in jumping and arrogance.

The Spring Festival has come to everyone inadvertently.

The days approaching the end of the year are often the busiest time for everyone in the aristocratic family. Even if you live in another courtyard, you will still see the hurried footsteps of all kinds of people. In just a few days, Shaonan City seems to have crossed time and space, bringing a group of 21 people together. The white-collar workers in the metropolis of the century have received the Great Xia Dynasty, and there are fast-paced footsteps and dialogues everywhere: expired contracts need to be honored or renewed, tributes and rents in the village need to be put into storage, and the benefits due to family members should be distributed. , the shops we operate need to be counted, and the important people have to meet one by one...

On the contrary, Cheng Jinzhou is as leisurely as a squirrel in the winter, just eats and drinks enough every day, and his front teeth show a foot when he smiles.Cheng's father and Cheng's mother were so busy all day long that they didn't even have time to urge him to do his homework, but the filial piety of the two astrologists allowed him to accumulate nearly a thousand taels of silver again.

Either way, knowledge is power, and if it depends on the monthly payment, he may not be able to hold a lot of money before marriage.

Seeing other people busy, my own laziness has shown its value. This kind of life is exactly what Dr. Cheng Da is looking forward to most, and the efficiency of copying books has improved in a short time.

However, what he didn't expect was that not only did Xiang Xin not make any preparations for the new year, but he even developed a strong interest in geometry. Together with Wu Zong, he began to dabble in real Euclidean geometry.If it was another star warlock, even the serious Liu Kuang star warlock, Cheng Jinzhou would not really pay attention to it, but Xiang Xin somehow saw Cheng Jinzhou's "greedy money". One hundred taels of silver, and consciously or unconsciously, the price of each question was controlled at around 30 taels of silver.

1000 US dollars to ask a question, this kind of treatment, let Cheng Jinzhou feel a little embarrassed to refuse.

On the day before the New Year's Eve, God seemed to be unable to restrain his old body from the wind and cold, and vomited large flakes of snow flutteringly, dyeing the winter earth like a stomach wall that had emptied its inventory.

Wind and rain can't stop the astrologist's desire to study. Just after noon, Xiang Xin walked into Cheng Jinzhou's small courtyard with a serious face, and handed over the "small gift" he brought to Shi Yan while frowning. Get out a few pages of straw paper.

Cheng Jinzhou put away his right hand that was waving in the air, picked up his teacup and asked, "What's the problem again?"

Euclidean geometry was a product of the third century BC, almost 2000 years behind the level of the Great Xia Dynasty, but its expression proved to be very appetizing to the star warlocks.Or it should be said that the astrology from the far west is born to like this seemingly completely correct deduction method, and the content is not more advanced than the current mathematics and science. Xiang Xin quickly learned it in depth, and the problem is natural more up.

This time was no exception. Xiang Xin prepared six questions, that is, the question of 180 taels of silver, but she hesitated for a moment, and took out the last page first, and said hesitantly: "Mr. Article [-] is a bit confusing."

Being called "Sir" by an astrologer - even if it is only a first-level astrologer, it is still a very glorious thing, Cheng Jinzhou took a sip of tea slowly, aftertaste in his mouth, before leaning on the back of the chair and laughing :"what is the problem."

Answering junior high school geometry questions that don't even know how to use auxiliary lines requires little thought.

"I think the fifth axiom, the axiom about parallel lines, seems to be proved by the first four..."

"The result?" Cheng Jinzhou was unmoved.Similar thoughts have been thought by almost every mathematician.The first four axioms of Euclidean geometry are simple, clear, and convincing. The fifth parallel axiom is different, long and complicated. As a postulate that should be self-evident, it obviously lacks Euclidean beauty.Therefore, this has almost become a classic proposition. For hundreds of years, countless people have tried to prove the fifth postulate through the first four postulates: if a line intersects two lines, and the sum of the two interior angles intersecting on the same side is less than two A right angle, then the two straight lines must intersect on the opposite side after being extended infinitely.

Of course, they all failed without exception, but like all classic math problems, the gift of failure is far greater than that of success.

Xiang Xin's face showed the frustration that Cheng Jinzhou imagined, but then she said surprisingly: "I feel that since it is difficult to prove that it is correct, I want to try using proof by contradiction to see what the consequences are of denying it. And then some weird results..."

A gust of cold air rose from Cheng Jinzhou's coccyx and went straight through his spinal cord. He couldn't even hold his teacup steady, so he stood up with a huff, and he could only yell in his heart: "Impossible."
