The old man is gushing endlessly on top, but the students below are of different shapes.

There is a learning progress just caught up, understood, and listened with relish; There are progress far from catching up, not understanding, there is a hurry, and busy taking notes; There is progress far exceeded, I understand, but I don't think it's interesting.

About one-third of the people in the lecture hall belong to the first type. Of the remaining two-thirds, 99.999 percent belong to the second category.

Chen Zhikuan is unfortunate and is the second type. He almost didn't understand what the old man said.

However, he didn't scratch his ears and cheeks in a hurry like most of his classmates who couldn't understand, and he didn't rush to take notes and wait for the tutorial class to end before going back to work.

Because he doesn't like mathematics, he doesn't hate it, it's entirely because he has to take mathematics in the college entrance examination, so he will learn mathematics.

The reason why he appeared here was just that he was listening carefully after class, but in fact, all his eyes fell on the short-haired girl in front of him, and he knew that it was the same as Tang Bohu who mixed into Washington as a low-level subordinate, all for the sake of picking up girls.

Misfortune and blessing are relied upon, and blessing and misfortune are lurking.

At this time, Chen Zhikuan felt that Lao Tzu's words were really a famous saying.

He was drinking water just now while eavesdropping on the girls' conversations, but he was unexpectedly discovered and made a big ugly appearance, so embarrassed that he had to leave there, losing the feng shui throne that he had finally mustered up the courage to obtain.

He should have been depressed, but now he was a little glad.

Because if you hadn't left there, where would you have sat in this seat.

And here, he can generously cast his gaze, and the girl's back and side face are unobstructed.

And as long as the girl doesn't look back, he doesn't have to worry about being caught peeking at all, it's just the right time and place.

Sure enough, she is worthy of being the girl with the highest appearance in the whole Huafu, 360° without dead ends, but unfortunately it is not good to take out the mobile phone to shoot during class time.

Chen Zhikuan was admiring the flawless side face without distraction, but he saw an interesting thing.

In the quiet class, where most of the students were listening attentively, the girl carefully took out a book from her bag, gently put it on the table, and quietly read it.

"So you can't understand what this teacher is talking about?"

Chen Zhikuan was excited that in the entire classroom, only he discovered this little action of the girl.

Thinking of the sentence just now, "Did you grow up drinking mountain spring water", he couldn't help but laugh. This quiet girl has such a quirky elf side.

Happy times always pass very quickly, and Chen Zhikuan felt that after a while, the bell rang after class.

"Take a break."

Here, the old man announced the end of class, and over there, Chen Zhikuan stood up, he planned to see what kind of book the girl was peeking at in class.

In the art of war, it is said that knowing oneself and knowing one's opponent will not be defeated in a hundred battles. In the case of pickling girls, the truth is undoubtedly the same.

Only by fully understanding the interests and hobbies of girls can they have a common topic and not find an entry point. Furthermore, in order to do what they like, in order to give full play to their gentleness and thoughtfulness and meticulousness.

It was at this time that the girl closed the book and let him see the cover of the book: Editor-in-Chief Shan Yan, Mathematical Olympiad, Proposer Lecture, Combinatorial Geometry.

When he saw the words on the cover clearly, Chen Zhikuan was instantly stunned.

He didn't know who it was, and he didn't know what it was, but he still understood the meaning of the words Mathematical Olympiad and combinatorial geometry.

After a long while, Chen Zhikuan sat down.

"It turns out that you don't understand, and you don't read extracurricular books, but you are not interested in the teacher's lectures."

Muttering to himself, Chen Zhikuan took out his mobile phone from his trouser pocket, opened WeChat, and sent a message to "Han Laomo": "A question, the Mathematical Olympiad Proposition Lecture on Combined Geometry edited by Shan Yan, what kind of book is this?" ”

After a while, the phone vibrated and the message came back.

"Don't you don't know what the Olympiad is, aren't you interested in the Olympiad, and ask what kind of demon this book is for?"

"You just need to sue me, is this book difficult?"

"How easy is it, how difficult is it?"

"Is it easy or hard?"

"Are you ready to get your hands on the book, or what's going on? I said, young people have a bright future, don't be so impatient. ”

"You mean, it's hard?"

"Let me make an analogy, there are several kinds of spicy, you know, a little spicy, slightly spicy, medium spicy, extra spicy, (perverted) spicy, this "Combinatorial Geometry" belongs to the kind of metamorphosis (perverted) spicy in the Olympiad tutorial book. For people like you who have never been exposed to the Olympiad, I must say, young people, cherish life, and stay away from the "Combinatorial Geometry" and "Number Theory" lectures of propositioners. ”

"That's an exaggeration, isn't it, I'm scared?"

"How do you think I'm doing in math?"

"Very good, we have won all the awards."

"But even if I have won the award, I want to die when I read this book now."

"You're all of this?"

"It's good to know, but what's the matter with you, suddenly asking about this book?"

"I said I had a classmate reading this book, would you believe it?"

"Which school, sophomore or junior?"

"My classmate, which school do you say you are from, sophomore or junior in high school?"

"Your school, a freshman in high school?"

"yes, that's why I wanted to ask you if this book is difficult."

“……”

"What's wrong?"

"I was hit badly with internal injuries, and the seven orifices bled out, I came with the wind and went with the wind......"

"Han Lao Mo" was hit by the wind, Chen Zhikuan put away his mobile phone, all kinds of thoughts came to his mind, and his mind couldn't calm down for a long time.

Even when the second class began, he was still stunned, immersed in his intertwined thoughts, until the end of today's math competition tutoring class.

But at this time, he returned to the sea and all thoughts were one, and he finally made up his mind to start learning Olympiad mathematics.

But just when he was about to find out from the math teacher how the first brother of the Olympiad should start learning the Olympiad, the math teacher talked to the girls.

Seeing this, Chen Zhikuan hurriedly got a little closer, and dropped out not far behind, exerting his tailwind ear.

"In Class 1, are you still used to it?"

"Everyone is as enthusiastic as Youwei, which is good."

"Teacher, didn't you see it, Lu Xi doesn't know how popular he is in the class. I saw the newcomer laughing, but I didn't hear the old man crying. We old people have been compared. ”

"Ahem, how was this class going?"

"From shallow to deep, transparent and easy to understand, it is refreshing to listen to."

"Then why did I see someone reading Mr. Tian's book?"

OK, someone killed himself, choked and couldn't speak.

"Don't be nervous, I know your progress, in fact, you really don't need to come to this Cheng Dù's tutoring class. The reason why I asked you to come this time is to let you know what the tutorial is about. ”

"So, Lu Xi won't have to make up classes in the future?"

"Suffice it to say, of course, if necessary, I would recommend you to go to class with your sophomores and juniors."

"It's not the same life, it's really envious of others."

"Classmate Yu, if you don't want to, you don't have to use it to make up classes, no one will kidnap you."

"In order to live up to the teacher's expectations, after careful consideration, I think it would be better for me to make up more classes."
