The days of learning black magic in another world

"The flame grass that is still indestructible, the ghost heart... the pages of the book that have been preserved for more than a hundred years, if the pages are really bad, go to the library to steal one... I'm sorry, Ms. Airol."

"Flame grass...ghost heart...where should I get it?"

"I don't think I've ever heard of ghosts anywhere. It stands to reason that the campus should be the place with the most ghost stories? Why doesn't Rhodes have any legends about ghosts..."

"There is also the immortal flame grass, what a ghost, how come you can't find any of them, do you really want to go to Raymond's house to steal it... Tsk, it's too difficult to steal a nobleman ..."

In Riemann's hard thinking, the math class at Rhodes College came again, which undoubtedly reminded him that he seemed to have an imminent task compared to becoming a magician-well, first become a mathematician, and be a socially important person. people.

Considering that his current secret ambition has become a magician, this cover is even more necessary.

"A point is something that has no parts."

"A line is long without breadth."

"The end of the line is the point."

"A straight line is a line with points evenly placed on it."

"Noodles are things that have only length and breadth."

"The end of the plane is the line."

"..."

"

"A circle is a plane bounded by a line, and a point inside it is equal to all the line segments connecting the points on this line."

"And this point is called the center of the circle."

"..."

"The above is the definition." 【Note 1】

"I don't expect you idiots to immediately understand the beauty and rigor of geometry. You just need to memorize these definitions first, understand?"

Mr. Pale Face raised his chin proudly, and looked at a group of blank-faced students under the podium with disdain. The moment his eyes touched Riemann, a trace of undisguised disgust flashed across his face.

"Seeing your stupid faces makes me angry."

After humiliating the stupid students in the audience, Mr. Pale Face began to explain geometry.

In Riemann's view, his thinking is a bit... oh no, to be precise, it is very jumpy.

People who have experienced modern compulsory education probably won’t be able to adapt to this kind of teaching. In fact, the last class was still addition and subtraction, and this class skipped to geometry. The jumping in the class was obviously more serious. Riemann listened to him talk about circles from triangles, and even talked about cutting circles on a whim.

Riemann glanced at the students around him, and sure enough, most of them were either drowsy, or they were holding on to their spirits but still looked confused.

With this kind of education... those who can learn mathematics well are probably true geniuses.

Riemann frowned while scribbling on the parchment to deduce the area formula of a circle. He didn't realize that the sound of his quill falling on the parchment "rustling" was other than Mr. Pale Face's passionate lecture. Even if the other students couldn't understand the only sound in this classroom, or because they couldn't understand it, they behaved with their tails between their legs, for fear of being noticed by Mr. Pale Face.

Therefore, when Mr. Pale Face's eyes fell on Riemann, showing deep impatience and anger, several students who had noticed that Riemann was writing things on his own could not help showing Snicker.

"Riemann—Mr.—"

Mr. Pale Face called him in a drawn-out tone, and Riemann blinked, not knowing what he had done to offend the bad-tempered teacher.

"Excuse me—what are you writing?"

This "you" is undoubtedly enough yin and yang to make Riemann stand up subconsciously and straighten his back.

He thought he had put on an obedient posture, and replied obediently: "Mr. Rochester, I am thinking about the method of cutting circles you mentioned."

"Thinking? Ha, how ridiculous is that word coming out of your mouth."

As the pale face's voice fell, there were a few titters around.

"So, may I ask you—what did you think about?"

With a move in Riemann's heart, he gave up his original plan of answering in a satisfactory manner, but explained the idea of ​​points: "Yes, Mr. Rochester, I have some ideas, I am thinking, in order to minimize the error as much as possible, we It is necessary to try to cut the circle thin enough and small enough, so why don't we just cut the circle into infinite pieces directly, so that the edge error can be ignored."

"Idiot! What an idiot! Infinity, ha, you can tell, you didn't listen to what I just said, did you? Infinite block, why don't you think about it, if that's the case, where do you go to find the area? Composed of length and width, you don’t even have width, it’s not even a plane, how are you going to find the area?”

So, there are no points yet, great... Riemann jumped for joy.

Mr. Pale Face was pissed off by him, how could someone say such a whimsical and stupid thing, he cursed furiously on the podium for 10 minutes, and finally left a sentence: "After class! Come to my office and copy the definition a hundred times !"

Riemann: "..."

Well, temptation always has a price.

If the first penalty copy is still a bit of a learning effect, the second penalty copy is purely punishment, and the definition of hell is much longer than numbers...

Riemann walked out of the basement with a sore wrist, determined to be cautious in his future math classes.

As soon as the candlelight at the top of the auditorium shone into his eyes, Redmond's figure appeared in front of Riemann.

The blond boy walked back and forth twice in front of Riemann while "tsk tsk": "A pariah is a pariah, and Mr. Rochester treats you so stupidly in a place like Class D, I underestimated you... How about, uninterrupted labor service and punishment, are you living a fulfilling life?"

Riemann nodded: "It's really fulfilling."

Redmond curled his lips in boredom. He shouldn't have picked a time when Little Polo wasn't around. This guy is indeed a pariah. He has a thick skin. No matter what he says, he doesn't get any response. It's really boring.

"Hmph, listen up, this young master has decided to give you a chance to look at what it's like to be a real noble. This Saturday, our Redmond family will officially move into the Gold Duke Manor. My father asked me to invite the Duke of Rhodes Some of my classmates came to the dinner party, of course you are definitely not my classmate, but it’s okay for you to open your eyes, take it, this is an invitation.”

The young man next to him threw out a golden-red invitation card, and Riemann caught it quickly. His slightly eager action made the faces of the three people on the opposite side show a trace of disdain, and Riemann just wanted to yell— —

"If you step through the iron shoes, there is nowhere to find it, and it takes no effort to get it!"

"What?! Redmond also invited you to the dinner party?!"

"This guy is definitely trying to make a fool of you!"

Little Polo stood up angrily, his face flushed.

Riemann: "Of course I know."

Little Polo: "Oh...that's right."

"No! No! I won't let this fellow Redmond succeed!"

"Don't I know what's going on in his mind? It's nothing more than a feeling that you can only go in school uniform, and you can't talk to other people about a topic, and you can't dance. He doesn't have to bother, just look at other people It's fine for people to laugh at you. Damn it, it's really insidious, and it will hide behind others!"

"Hmph, just watch him! Watch me, Mr. Polo, crush his illusions one by one!"

"Come on, let's go to Figkins to order you a dress!"

Riemann: "..."

He slowly climbed onto the bed: "No need."

He just wanted to pick a few plants of the Inextinguishable Flame Grass, and there was no need for a big transformation.

But little Polo became so stubborn that he even forgot that he was facing a terrible "magician", and forcibly dug Riemann out of the bed.

Riemann: "..."

Should it be said that a bear is a bear?Even being beaten doesn't last long.

Although the night view of this city is still different from the "cities that never sleep" that Riemann saw in his previous life, it also has a special flavor.

Riemann was sitting in the Polo family's carriage, with a cushion made of velvet under his buttocks, which greatly cushioned the bumps of the carriage on the uneven stone road.

He opened a corner of the curtain, and there was a row of kerosene lamps on the side of the road. The dim, hazy, and blurred lights enveloped the city in a fairytale-like fantasy atmosphere.

The surrounding carriages gradually increased, and Riemann guessed that this probably meant that they had entered some main road...

Soon, when he lifted the curtain, what he saw was not only the dim kerosene lights on the side of the road, but rows of shops. They finally stopped at the door of a shop about three meters high.

The ceiling and doors of this store are much higher than those of other surrounding stores, and with the golden decoration inside, it looks open and expensive.

"Ah! It's Mr. Polo, welcome!"

A half-white-haired but hale and hearty gentleman greeted them with a smile on his face. He looked at Riemann: "This must be Mr. Polo's classmate. He really has the same temperament as Mr. Polo."

Riemann: ...I always feel that I have not been exaggerated.

Little Polo was very useful and very happy. He walked into the shop and flung himself onto the sofa, as skillfully as if he had returned home.

"Uncle Carl, help him find a dress for the dinner at Redmond's house, so it must be! The best one! It looks luxurious at first glance! It has temperament!"

The old man called "Uncle Carl" looked at the little Polo who was chattering and making requests. Little Polo came to him to order clothes since he was a child. He almost watched the child grow up, so he naturally knew that he and Sidmund Who didn't have a deadly rival when they were teenagers, so he interrupted the other party with a smile: "Mr. Polo, I think, I have fully understood your request."
