When leaving the cafeteria, Bi Wanqing smiled and said to Wu Bin: "I really want to arrest you now and let you study competition physics, but do you remember our agreement?"

"Well, all subjects are pulled to high scores."

"Haha, the high score is set by yourself, but I think it's you, no problem, your kid's head will shine."

'It's good not reflective ......'

Wu Bin, who was accustomed to complaining in his heart, hurriedly shook his head, "No, no, it's disrespectful, it's disrespectful." ’

"Don't shake your head, you're smart and hard enough, come on, I'm waiting for you in the office to come to me."

After Bi Wanqing finished speaking, he turned around and left, but before he could take two steps, he suddenly turned around and said, "Oh yes, if you want to eat with me, you are still welcome, and you will bring a little more dishes from your cafeteria aunt." ”

"Hahaha, okay, Mr. Bi." Wu Bin smiled happily.

When Bi Wanqing walked away, Wu Bin was also about to go back to the classroom, but before he could take two steps, he was suddenly patted on the shoulder.

Wu Bin, who was frightened, took two steps forward before turning around, and found that the person who patted him turned out to be Su Yun.

"Whew...... Teacher Su, don't scare me like this. Wu Bin patted his chest and let out a long breath and said.

"I'm sorry, I didn't expect you to be so timid."

"What does this have to do with cowardice!? Teacher, this reaction is self-protection in the process of human evolution, is it the increase in adrenal hormones, so it will cause ......"

"Okay, okay, it's still a set, it's the first time I've heard such a high-sounding novel of guts." Su Yun covered her mouth and smiled.

"Even if you are a teacher, I want to emphasize that this is not timidity, this is adrenal ......"

"Okay, okay, it's the teacher who said it wrong."

Seeing that Su Yun was willing to admit her mistakes, Wu Bin also nodded with satisfaction.

Looking at Wu Bin's proud appearance, Su Yun couldn't help but sigh with emotion: "It's really the first time I've met a student like you, and you can still talk to the teacher, no wonder so many teachers surrounded you just now, you still have a big heart." ”

"Huh? Teacher, you were there just now. Wu Bin asked in surprise, he really didn't notice this teacher.

"Yes, sitting at the table behind you, I thought that I would have something to say to you after you talked to those teachers, so I waited for a while, I didn't expect you to talk for so long."

"Huh? Teacher, are you looking for me? Wu Bin was stunned for a moment, and then immediately waved his hand and said, "Teacher, I promise, I really didn't say anything about the infirmary that day." ”

When Wu Bin spoke, the two cafeteria aunts who had just come out happened to hear it, and immediately showed expressions of both "Ying Tstin" and "a rowing" at the same time.

When Su Yun saw it, she hurriedly said, "Who told you this!" ”

"What else is there to do?"

Su Yun was almost angry at this moment, looking at the pace of the two canteen aunts, she was obviously very interested in the follow-up development.

"I wanted to talk to you about the learning problems of high school juniors you talked about last time."

"Oooh...... Is it easy to use? ”

"Well, some students do like the simple and crude set of points you said, and some are even willing to take the initiative to come to me."

"That's good."

"So I have some new questions for you."

"That...... Teacher, you're the teacher, aren't you? ”

It was the first time that Wu Bin had met such a "shameless questioning" teacher.

Su Yun's face turned red after hearing this, "But I'm teaching students like you." Su Yun said and sighed: "Actually, I also tried to talk to those students in our class, but they are always too nervous and rarely express their opinions, which is like you, old fritters." ”

"Hey, teacher, it's not good that you're looking for me to help me and hurt me."

"I'm praising you. Would you like to help the teacher again? ”

"When a teacher asks for a request, how dare a student refuse."

For a teacher like Su Yun who is willing to "ask questions without shame" to improve his teaching level, Wu Bin really can't think of any reason to refuse her.

"Then the teacher will thank you in advance."

After Su Yun finished speaking, she glanced behind her and found that the two canteen aunts had already gone away, so in order to prevent Wu Bin from "speaking amazingly", she said to him: "Then you can go with the teacher, don't worry, it won't delay you too much." ”

After nodding and following Su Yun, Wu Bin originally thought that she would take herself to her office, but she didn't expect to come to the chemistry laboratory, it was lunch break, and naturally there was no one here.

However, Wu Bin figured it out after thinking about it a little, if other teachers saw Su Yun in the teacher's office asking a senior high school student for teaching methods, I am afraid that the painting style is a little weird.

"Then I'll ask directly, last time you told me that you suddenly started studying because you found the joy of learning, can you give an example? What kind of fun suddenly drew you in? ”

It seems that this teacher still hasn't given up on the idea of bringing the poor students up. ’

After thinking about it, Wu Bin tried hard to recall his views on them in the more than a month of dealing with knowledge.

"Teacher, have you ever played a game?"

After thinking for a while, Wu Bin asked.

"Games? Super Mario kind? Su Yun replied.

"Also...... Sort it off. Wu Bin reluctantly nodded and continued: "As for the game, it is one level after another, and the same is true for learning, just take the calculus I just came into contact with, it makes me understand a little bit what I am learning high school math for." ”

Su Yun listened quietly and did not interrupt Wu Bin.

"Personally, I think the core idea of calculus is to divide an irregular shape into an infinite number of infinitesimal microelements, and then add these microns together to get the total amount, which is very useful for solving various formulas."

Su Yun nodded in approval.

"Then my fun point, that's it, set calculus as a big boss, if you want to defeat it, you have to have equipment, skills, and ......"

Seeing Su Yun's confused look, Wu Bin stopped, thought for a while, and continued: "Then let's put it another way, it's a tree of knowledge, I have to light up every branch of it, so that I have enough ability to defeat the boss, can you understand?" ”

"Well, I understand, you can go on." Su Yun nodded.

"Anyway, most of the students must understand." Wu Bin is still very sure of this, although he is not interested in the game now, but the students who are interested still account for the majority, and this example must be the easiest for them to accept.

"Okay, so the first level, start with the collection, why learn the collection? It's because you need to define a range and a range of values to accurately express a function, so after passing the first level of collection, I lit up this skill and mastered it, right? ”

Su Yun couldn't help but nod after hearing this, and praised: "It's a little interesting, go on." ”

"Mastering sets is to challenge functions, and many of the limiting properties of functions are obtained through sequences, so in order to challenge functions, I have to go through the sequence.

Wu Bin said and gestured with his left and right hands, "After I have mastered the two skills of number series and gathering." I have the ability to challenge the little boss of the function, and when I defeat the function, I will be able to pass the derivative level, and the derivative is differentiation, which is the premise of learning calculus. ”

"Now, I have the ability to challenge the big boss of calculus, but some higher-level calculus, these abilities are not enough, for example, the weakness of some calculus bosses is Euler's formula, and in order to learn Euler's formula, you have to pass the level of imaginary numbers first."

Hearing this, Su Yun was left to nod.

"Actually, I'm talking so much, just to prove one thing, high school is by no means an exam-oriented education, every layer of learning is a ring, one level after another, you don't defeat the boss of this level, forcibly challenge the next level, this is the same as a level 10 white trumpet, you have to fight the boss of the level 30 copy."

Seeing that Su Yun fell into a state of confusion again, Wu Bin had no choice but to stop and explain: "In short, if you say this to the students, they will definitely understand, or you can also choose to go home and look up keywords such as equipment, dungeons, and bosses on the Internet." ”

"Okay, I'll look it up." Su Yun nodded seriously, and then said: "You can summarize this set of theories is really powerful, this is not only to increase the fun of learning, but also to give me a new concept of teaching, many students in our class do not have a solid grasp of some basic parts, so they always focus on the big questions." ”

"Huh~ This is called the head iron, the challenge of leapfrogging, and then being beaten by the BOSS has no confidence left, in fact, the way of playing is not incorrect, some geniuses can indeed rely on fancy operations to hard anal past, but ordinary people can't, okay, I know you don't understand the teacher again, or you go home and check the words of various games, let's discuss it next time?"

"Okay, then it's settled, I'll come back to you when I understand this." Su Yun nodded several times after speaking, "I really appreciate your answer, it helped me a lot, I will invite you to dinner in return when I come to you next time, then I will go back to the office first, goodbye." ”

"Okay, goodbye, teacher."

The teacher and student waved goodbye, and Wu Bin stretched his waist and walked towards his classroom.

His next goal is to defeat the boss of chemistry.

When he returned to the classroom, everyone in the class who saw him greeted him, and he didn't ask much about the competition, after all, it was another world for them.

"How's the test, I see that Zhang Qiu's goods come back and look like they have nothing to love, it's very difficult, right?"

Waiting for Wu Bin to sit back in his place, Gu Fan leaned over and asked in a whisper.

After hearing this, Wu Bin first nodded solemnly, and then approached Gu Fan and whispered: "It's very difficult, I can probably get a full score." ”

Gu Fan was stunned for a moment after hearing this, and then immediately reacted and shouted: "Pretend, you continue to pretend!" ”

"Whatever you want~"

Wu Bin shrugged his shoulders and took out his sophomore chemistry book.

But after a while, Gu Fan came over again and asked, "Can you really get a full score?" ”

"Shhhh

Wu Bin pressed his index finger to his lips and whispered to Gu Fan.
