Listening to Han Shilan's mocking voice, Yang Feng smiled faintly, didn't care, and then said: "Actually, these are very simple, you can take a look at these auxiliary lines I draw." ”

Han Shilan glanced at Yang Feng, her face was still cold, and when she saw the auxiliary line on the scratch paper image, her eyebrows frowned, and her beautiful eyes suddenly flashed a trace of surprise.

That's right, after drawing these auxiliary lines, the idea of the whole question came out, Han Shilan looked at Yang Feng with big eyes and said, "This... Do you really know this question?"

"Of course. Yang Feng nodded, took the water-based pen in his hand, and explained to Han Shilan while writing: "The first problem is very simple, it is easy to find a breakthrough according to the connection of auxiliary lines, and use some geometric properties of the ellipse......"

Yang Feng kept writing a small question in his hand to solve a small question, and the process was clear and smooth, organized, some of them were still not taught by the teacher, Han Shilan's little head beside him was all leaning over, listening carefully to Yang Feng's explanation, feeling as if he was just a scumbag in elementary school, and he couldn't even say a word.

The little heads of the two people were in close contact like this, but they didn't notice.

And Han Shilan was very surprised in her heart, she didn't expect Yang Feng to actually solve this problem, could it be that he deliberately didn't write it before? Or did he just learn it after listening to the class?

"How is it, do you understand?" Yang Feng turned his head to look at Han Shilan, and found that the two of them were about to touch their noses, and suddenly both of them bounced away as if they were frightened.

Han Shilan's pretty and cute little face flushed with a touch of red, her big eyes looked at Yang Feng without blinking, and her red lips said lightly:

"Yang Feng, how did you know this question?"

"Uh..." Yang Feng was a little stunned, he couldn't say that there was a hooligan in his body... No, a full-time system.

Then, he said with a faint smile: "Actually, I would have known these for a long time, but I just don't want to do it?"

"Don't want to do it?" Han Shilan's eyebrows frowned slightly, and she murmured, is he the kind of student who loves to pretend to be a pig and eat a tiger?

I was so worried about him before, why did he fall, he was hiding his strength, no wonder he was so powerful in the first year of high school, how did he become so bad in the third year of high school, he was hiding his strength, thinking that he had been worried about his studies, it seemed that he was worried in vain, and suddenly there was a nest fire in his heart, and then there was a burst of confusion.

Maybe he wanted to show it in front of himself.

"If you don't understand any of the questions, I can teach you, one-on-one, you're making a lot of money. Yang Feng put down the pen in his hand and said a little carelessly.

"Hmph... I don't understand it! Who rarely teaches you! I'll see for myself. Han Shilan snorted angrily, pouted angrily, turned her head to look at the record on the scratch paper, and no longer paid attention to Yang Feng.

"It's strange, I taught her so patiently, and she was still angry? Women are really strange creatures, it seems that as the saying goes, a woman's heart is a needle, and it's true." The corners of Yang Feng's mouth twitched fiercely, and he muttered to himself.

At this time, Teacher Dong, who was on the podium, hooked the corners of his mouth with an old fox breath and said, "Students, when the time comes, which of you will come up and answer, or add an assignment as usual?"

Suddenly, all the students below exploded.

"Don't, Mr. Dong let us live, you see that we write homework until midnight all day, and suddenly die at home one day, what can we do..."

"That's right, Mr. Dong, you're the most handsome, don't add homework today..."

"Teacher Dong, this question is so difficult, you are obviously cheating us..."

“………”

Han Shilan looked at the classmates around her who were all blown into pots, sighed slightly, and said to the same table: "Yang Feng, you go up and solve this problem, otherwise you will have to add homework." ”

"I don't want to go up, you go up, anyway, I'll write the answer on your scratch paper, just copy it. Yang Feng waved his hand and said, I don't want to go up and pretend to be forced, what's the point of pretending to be forced in front of these classmates.

"Didi, when a student's occupation is detected, is automatically activated. ”

"Ding-dong ———"

"Assignment content: Make your classmates surprised by how hard you pretended. ”

"Quest Reward: One Class Convertible Scroll (Swapped)"

"Task failed: None. ”

"I didn't want to pretend, but you wanted me to pretend..."

Yang Feng covered his head and said secretly in his heart.

"Didi——— system checks the situation of the surrounding things, and then forms a task according to the current situation. ”

Anyway, it's actually nothing, isn't it just pretending? It's not much difficult for me now.

Yang Feng stood up and said to Teacher Dong, "I'll do this question." ”

As soon as the words fell, the whole class was dead silent, silent.

"Okay, classmate, come up. Teacher Dong smiled slightly and said.

The corners of Yang Feng's mouth rose slightly, picked up the chalk on the podium, and began to draw auxiliary lines on the topic, and then began to explain them one by one.

"I dare say, he went up and absolutely scribbled..."

"Did he still think this was the topic of the first year of high school? If he writes it, I'll eat it at the same table. ”

"Damn, what are these two goods going up there to pack? ”

“………”

Han Shilan was different from them, Yang Feng explained the whole process to himself just now, a smile crossed the corner of his mouth, and he muttered: "It's not that you can't say it, why did you go up again." ”

When she saw Yang Feng solving problems seriously on the blackboard, it was as if she had returned to her freshman year of high school, watching him appear on the podium again and again to solve problems.

At that time, he had a lot of girls secretly sending Qiubo.

Yang Feng took the chalk in his hand and wrote from the top of the blackboard to the row below, and a confident smile hung on his delicate face.

Teacher Dong, who was on the side, pushed his glasses, and a trace of surprise flashed in his heart, he didn't expect this student to really solve it, not only that, but the method used above was actually simpler than what he had solved before, and it was clear and clear.

The male and female students below looked at each other and talked one after another.

"He... You can't really do it, will you?!"

"I couldn't read what the hell it was, but I thought he was scribbling. ”

“………”

Half of the blackboard was filled at the moment, Yang Feng put the chalk back, patted the ash on his hands, walked off the podium, returned to his position, and glanced at Han Shilan.

Han Shilan's beautiful eyes sparkled at Yang Feng, and said, "How can you be so powerful?" You can even write this finale topic, don't tell me that you are hiding your strength." ”

"Uh..." Yang Feng was a little speechless, could it be said that he had obtained knowledge with the system?
