Lu Mingfei: Hogwarts repeater

Chapter 6 Lu Mingfei: I am a mathematical genius!
  "By connecting two points ab, we can get the intersection point ef..."

In the morning, in the classroom of Grade 1 and Grade 2 of Shilan Middle School, a mathematics teacher with a distinguished "Mediterranean" hairstyle was explaining a space geometry problem.

Lu Mingfei sat in his seat, looking up at the blackboard from time to time, writing and drawing on the newly purchased notebook with a black pen in his hand.

His seat was in the front row, but by the window, right in the teacher's "monitoring blind spot."

In the past, he would either stare out the window and be in a daze as the leaves rustling in the wind or some other creature attracted his attention, or he would look at the teacher on the podium while no one was paying attention. direction and glanced at Chen Wenwen at the other end.

Of course, he didn't dare to stare all the time, otherwise what if others knew that he liked Chen Wenwen?
  But now, he is not free.

Lu Mingfei kept looking at the blackboard and writing and drawing in his notebook. It was not because he was suffering from intermittent smugness and wanted to study hard. After all, he has always suffered from the "great ideal" of constantly eating and waiting to die... He looked at the blackboard just to make sure that the teacher had not noticed him and would not come over to confirm what he wrote in his notebook.

If anyone else saw what he wrote in his notebook, they would just be confused.

Those were not math class notes, but a lot of English. At first glance, it doesn’t look like an article, word, or English poem, but a bunch of unknown letters spliced ​​together. There are occasionally a few normal words in the middle, but overall it’s just a bunch of sentences that don’t follow the next. Messy.

Whether you know English or not, it probably looks like a heavenly book. You might think that Lu Mingfei is practicing how to write English handwriting well.

Only Lu Mingfei himself knew that these letters were all abbreviations of nouns, with only necessary effect words in between as connections. The noun abbreviations were naturally unique to the wizarding world.

After this simple encryption method that is impossible to decipher without a dictionary, Lu Mingfei can safely record the knowledge he learned at Hogwarts during this period, which can be used as a review and to keep notes for later use. , and don’t worry about others understanding it at all.

The task of mining all the knowledge learned in a month from the brain and then writing it out in this encrypted way is simply not something that an ordinary person can do.

But Lu Mingfei is no longer an ordinary person. The "Bafe Brain-Refreshing Agent", "Intellect-Enhancing Agent", "Enhancement Agent" and many other medicines in his body are all working, and they have not weakened at all!
  There was no reason why Lu Mingfei was so anxious to record all this knowledge - Snape's "threat" before returning was still vivid in his mind, and Lu Mingfei saw the hourglass again after another attempt. As previously guessed, the hourglass turned upside down again, and this time the flow was much faster than when Lu Mingfei was at Hogwarts!

Lu Mingfei estimated that if the silver sand kept flowing down at this rate, it might run out in a day or two, and by then, he should be able to travel back to Hogwarts again.

This means that he will face a monthly exam at that time.

This month's test was from Snape. Lu Mingfei didn't dare to think about the consequences he would face if he answered any question wrong. When Snape mocked people, his attack power was at full capacity!
  Although it is estimated that there will be no actual punitive measures, it still sounds uncomfortable.

As Lu Mingfei was writing, he suddenly sighed silently.

Others who have traveled across the world and come back have mastered martial arts that are invincible, solved world crises, brought peace to the end of the world, and then brought back beauties. How could it be that when it was his turn, he not only relied on "taking drugs" for his martial arts skills, but also stayed in school step by step?
  You even have to worry about the exams that are coming soon!

Classmate Lu Mingfei felt very embarrassed.

At the same time, the math teacher on the podium finally noticed something unusual about Lu Mingfei.

Although the school year has not long started, as a teacher with many years of teaching experience in a noble and high-end school like Shilan Middle School, the math teacher already has a rough understanding of the grades and personalities of the students in the class.

Just like an old police officer can tell at a glance whether a person has a problem after arresting too many criminals, an old teacher also has similar experience in judging students.

"Could it be that he suddenly became enlightened and was ready to study seriously?" The math teacher had doubts in his mind. He had seen such examples. It is not uncommon for someone to suddenly study hard and make progress as soon as he became enlightened.

However, he was not in a hurry to confirm. Instead, after finishing the question, he knocked on the blackboard and coughed twice: "Ahem, this question is over. There is still some time before get out of class ends. Let me say something. Other things. The school is planning to open a class to improve the Mathematical Olympiad competition..."

Lu Mingfei raised his head slightly.

The Mathematical Olympiad Competition Improvement Class is a tutoring class independent of the curriculum and offered by Shilan Middle School. As the name suggests, all students who join it are trained towards the Olympiad Mathematical Competition. The main purpose is to gain extra points in the college entrance examination through the Mathematical Olympiad competition, or to win the Olympiad gold medal, join the national training team to participate in international competitions, and be admitted to the country's top universities. route.

Of course, the latter has never appeared in the history of Shilan Middle School - without him, it would be too difficult.

If you don't know something like mathematics, you just can't do it. The Mathematical Olympiad has raised more than one "level" on top of this.

What this thing relies on is talent. A genius who knows how to do it will know it right away, without even having to teach him. Those who don’t know how can only struggle in the sea of ​​questions, relying on the tactics of the sea of ​​questions and the problem-solving ideas summarized by various famous teachers and a certain IQ to get some extra points for the college entrance examination... Even if it only reaches that point, it is already better than A crowd of people.

Those who win gold medals, join the national training team, and eventually stay on the team to participate in international competitions and win gold medals are the geniuses among geniuses.

Rare in the true sense!

Lu Mingfei lowered his head again and continued his "re-engraving" project. He has no interest in participating in any mathematics olympiad competition improvement class. Not to mention that he is very self-aware of himself. He knows that if he doesn't have the talent, even if he does have it, wouldn't it be good to use that time and energy to learn magic? Come on, he can travel through time now!

"Then it's still the same old rules. I will give you a Mathematical Olympiad competition question here and give you one day to go back and check the information, or use any other method. As long as you can solve it, you will be qualified to enter the Olympiad advanced class. Of course. , I don’t have a problem with you cheating. Anyway, you won’t be able to cheat in the Olympiad by then. We are all fifteen or sixteen, so we should have thought clearly, right?”

The math teacher was joking with everyone while writing the questions on the blackboard.

"This is not considered homework. Of course, everyone can do it in their spare time. Maybe you can find out that you have talents?"

Everyone in the class looked at each other in confusion. At first glance, this question seemed not complicated, but when I thought about it carefully, I felt that I had no idea how to start. Besides, who would be looking for trouble by doing Olympiad math questions when they have nothing to do? They really need to be talented, as early as in elementary school and junior high school. It should show up!

The math teacher didn't care about this. It would be best if there was a genius, but it didn't matter if there wasn't. Anyway, if there were a few people in the class who could answer it, he already knew it.

Compared to this, he was a little interested in Lu Mingfei, who was still taking notes... Could it be that Lu Mingfei was going to try to solve this problem?

"Yes, whether you can solve it or not, it is good to have the heart to study hard."

The math teacher thought to himself, preparing to give Lu Mingfei some encouragement.

"By the way, I noticed in class today that a classmate has been taking notes carefully. This is a good habit worth promoting... Lu Mingfei!"

Lu Mingfei froze. He felt that everyone in the class was looking at him at this moment. Some were surprised, some were doubtful... Of course, doubts were the majority. After all, there was his previous image as the basis for judgment. In fact, when the math teacher said that someone was taking notes seriously, Lu Mingfei had already realized that something was wrong, but it was useless to realize that. This little time was not enough for him to temporarily compile a real notebook of mathematics class notes. He won't stop!

"It's broken, you're overdoing it!" Lu Mingfei shouted in his heart.

If he was given a chance to turn back time, he would rather sleep on his stomach and be picked up and forced to stand than have this situation happen!
  It doesn't matter to anyone else. What matters most is what Chen Wenwen will think. Will she laugh at him after seeing him make a fool of himself?
  But obviously, there is no such thing as a regret pill.

Even the math teacher walked towards Lu Mingfei under the gaze of everyone, as if he was preparing to see how Lu Mingfei was doing with his notes.

"Taking notes is really a good habit. Some things you didn't understand in class can be reviewed after class. You can learn from Lu Mingfei..."

The math teacher walked over as he spoke. His eyes fell on the notes in front of Lu Mingfei, and the rest of his words suddenly stuck in his throat.

"English?"

The math teacher's voice seemed to be squeezed out from between his teeth.

The whole class burst into laughter. This sudden turn was so dramatic. The skeptical people felt satisfied because their suspicions were verified, while the surprised people felt funny because they were shaken. Lu Mingfei even clearly heard someone say to others, "Holy shit, I almost really believed it." Then others He replied, "How is it possible? You don't have to think about it."

Yes, after all, my previous performance was like this, and the facts have been verified again... If the same performance happened to others, I would probably think so, right?
  Lu Mingfei thought to himself, hanging his head amidst the roar of laughter.

"Quiet!" the math teacher shouted, making the whole class instantly audible.

Lu Mingfei waited, prepared to be questioned or even ridiculed by the math teacher, then collected his notes and ordered another parent meal.

But in the end, what he waited for was a notebook handed back to him.

Lu Mingfei was stunned for a moment and raised his head cautiously.

"Everyone can have their own choice. As a teacher, I respect you and hope that you can succeed on the path you choose." The math teacher took a deep breath and forced a smile on his face.

"At least you are really working hard, but the time and place of your efforts are a bit wrong. Pay attention next time, okay? Mathematics accounts for a large proportion of the score..."

Lu Mingfei took the notebook blankly and watched the math teacher turn around and walk towards the podium. The Mediterranean place looked so dazzling under the sunlight coming directly from the window... Okay, this is a bad sentence, but in short, Lu Mingfei Fei suddenly felt his eyes were a little sore.

The math teacher must be very disappointed, right? After discovering that a student who was diligently taking notes in his own class was actually taking notes in other subjects, would he suspect that his teaching was not interesting enough, causing the student to completely lose interest?
  Lu Mingfei is a very simple and ordinary person. He is cowardly, hesitant, cowardly, has no merits, can only talk bad words, and is okay in the world... In his short life, few people are good to him, so once someone is good to him, he I will try my best to repay you a thousand times.

Lu Mingfei was not very clear about his personality. He just felt that he was hot-headed, and then he wanted to do something to save the heart of such a good math teacher who might be broken.

He looked past the math teacher's back and saw the Mathematical Olympiad competition question on the blackboard, and a bold idea naturally emerged in his mind.

Hundreds of numbers suddenly emerged in his mind, arranged, combined, and calculated. One number after another was conditionally selected and eliminated, increasing in order... At this moment, his brain's calculation speed was comparable to that of a computer A real computer! The number that meets the conditions is calculated almost instantly!
  Yes, Lu Mingfei has no talent for mathematics, and he has never understood any methods for solving Mathematical Olympiad problems, but this does not prevent him from becoming super smart after taking the "Bafe Brain-Refreshing Agent" and "Intelligence-Enhancing Agent" Use your strong brain to do a simple superposition calculation!

"Teacher!" Lu Mingfei stood up suddenly and said, "The answer is 408."

The entire class, who remained quiet, did not immediately realize what Lu Mingfei meant by the number in the answer.

Until they saw the math teacher pause in his footsteps and turn around with unconcealable surprise on his face.

"What did you say?" the math teacher asked.

"The Mathematical Olympiad question on the blackboard," Lu Mingfei felt that his brain was a little congested and his nose was numb, but he still managed to speak out, and the more he spoke, the more smoothly and naturally he said, "The answer is what I asked for. The smallest positive integer is 408."

The whole class was in an uproar. Everyone looked at Lu Mingfei with disbelief, suspecting that he had lost his mind.

That's a Mathematical Olympiad question! How can anyone give an answer so quickly? I'm afraid Lu Mingfei is crazy and wants to save face by randomly talking about numbers!

"Have you seen this problem before?" the math teacher asked again.

The math teacher's question aroused an even more heated uproar among everyone - Lu Mingfei got the answer right? !

"No, I have never seen this question, teacher." Lu Mingfei's voice completely stabilized.

"Yes, I think so. This question is my original creation, but it is difficult enough and has definitely not been leaked. So you are..." The math teacher nodded and looked at Lu Mingfei, with a hint of unknowingly revealed in his eyes. look forward to.

And encouragement.

Perhaps it was this expectation and encouragement, coupled with the previous tolerance, and the medicine flowing in the blood... Everything was mixed together, igniting something like gunpowder.

Lu Mingfei instinctively took a deep breath, suppressed the heat that came from unknown sources, and decided to walk to the dark side.

When he spoke, his voice was not loud, but it succeeded in covering up all the noise in the class and reaching everyone's ears clearly.

"I just figured it out in my mind, teacher. In fact, this is the reason why I wrote English notes before. The class was too simple and I understood it, so I had nothing to do... But I will pay attention next time."

He finished and sat down.

All that's left is dead silence.
