Blind people can count things several times slower than ordinary people, because people's attention is often in listening, reading and writing, and the combination of the three is the fastest. The writing process distracts the mind, and black and white words can help recall, but in the world of the blind, without the memory pictures in black and white words, most of the process has to rely on mental arithmetic.

And mental arithmetic, not everyone can.

"Isn't she deliberately looking for an excuse to change classes?"

"Isn't that better? There's a blind man in the way."

... hearing the comments of the students around him, Zhou Yuchen proudly raised the corners of his mouth, and the speed of his writing could not help accelerating.

He has made up his mind today.

"The answer is root three, teacher." in a whisper, a pleasant voice suddenly sounded.

what? Zhou Yuchen made a sharp stroke with the tip of his pen and suddenly looked back. He saw that the girl was still standing by the window without any calculation tools. The radian of his smile was even the same as before.

But the answer came out of her mouth, "hmm? Is it root three, teacher."

The teacher on the podium was also stunned. When he heard the second inquiry, he responded, "Oh, well, let me see... Yes, the answer is root three."

Not only did the teacher open his mouth, but all the students watching the excitement under the podium were shocked.

Zhou Yuchen looked back in amazement at the formula he had only calculated half, "this... Impossible, has she seen this problem long ago?! teacher, come out again, I'll compare with her again."

He jumped up immediately and questioned whether the girl had done the problem in advance.

"I made this question myself. Forget it, let's do it again." the math teacher looked a little unhappy, but he was also curious about the unexpected test results, so he thought about it and wrote a question on the paper on the spot. "All of you are ready to prepare draft paper to calculate together. This problem is a little super outline and will be more difficult."

The third year of senior high school is basically a review course without new knowledge points. This time, the teacher thought about the compound question type of Mathematical Olympiad. After a long series of formulas were written on the blackboard, he read them through again.

"I'll go. It's so long." the students at the bottom have a headache when they see the length and complexity of the formula, and they feel dizzy when they hear the teacher say it.

The math teacher also regretted after reading it. After all, this topic is very complex. Even if she closes her eyes, it is difficult to remember it again, "cough, if new students need it, I'll read it to you more times."

Oh, I can't remember this topic hundreds of times. Zhou Yuchen thought badly while breaking the root sign.

"No, sir." Qin Qing shook her head and refused the teacher's kindness. Her black and white eyes looked at the nothingness ahead, as if thinking about something. When all the students scratched a rustle on the paper with their strokes, she whispered: "This question is wrong, teacher. The plus sign in the middle should be replaced by a minus sign in order to get the final answer. It's sixteen."

The voice fell, all the strokes stopped, and there was no sound in his ears, but Qin Qing could imagine that the people were full of surprise when they looked at him.

The math teacher was also shocked. She quickly opened her notebook and found the math problem she accidentally saw in old books and periodicals. At that time, she thought it was interesting, so she copied it. Today, she wrote it casually on a whim. The formula was complex and she didn't proofread it just now. Now when she looked carefully, she found that the addition and subtraction symbol in the middle was really wrong.

"How did you know..." the math teacher blurted out subconsciously.

Qin Qing didn't mind the other party's query, and said faintly, "because the plus sign can't be solved, so I tried the minus sign."

Try? With what? The math teacher looked around blankly. After stopping at the girl's empty hand for a while, his eyes widened and widened. Finally, it was almost like he couldn't bear the shock. He trembled slightly, "did you... Calculate it in your mind?"

"Yes." Qin Qing's pink lips opened and closed, and two very shallow words floated out. After that, the surrounding air fell into a dead silence again.

"Qin Qing... You came from Yuheng high school. Your original score in this school is..." The math teacher only learned this morning that there was a transferred student who was blind, so after receiving a new set of teaching materials, she casually stuffed each other's files into the textbook. At this time, the pages were rattled by her. As a teacher, she was so rude on the podium for the first time. When she looked up the report card and saw the score on it, she felt herself My chin is about to fall to the ground, "full score, full score, full score... Jingda! You are a special recruit of Jingda!"

When the two words Jingda hit the classroom, the whole classroom was blown open with a bang.

"No, is it the super famous Beijing University in the mainland? Didn't our school get one the year before last?"

"I heard Yuheng had two special moves from Beijing University before. I didn't expect it to be true or a blind man!"

... amid the discussion of the crowd, Bessie looked at the girl on her side in surprise. The latter felt her move and lowered her eyes to her line of sight. The eyes behind the glasses were like beautiful black pearls.

Bessie suddenly felt that the girl in front of her was stronger than anyone in the class, even if she couldn't see it.

"Teacher, I don't know if I can announce the results. Class is almost over. I don't want to waste everyone's time."

Zhou Yuchen, who was sitting in the front row, heard this, and his stiff back bristled up.

The math teacher coughed twice, looked at Zhou Yuchen with pity, and said, "this test, Qin Qing won. Zhou Yuchen, you can't bully new students in the future. You have to learn more from others."

Just now she sympathized with the disabled girl. Now when she saw the report card, she wanted to light a candle silently for the boy who kicked the iron plate.

IQ 180, this is simply a unilateral crush on IQ, there is no fair game.

However, Qin Qing was quite at ease. Hearing the footsteps coming from the front row, she gently clicked her fingertips on the table.

"Come on, what do you want? Do you want me to apologize to you in public, or I'll see you take a detour in the future?" Zhou Yuchen said rudely, his tender face red.

"I want to apologize, but it can't really eliminate your prejudice against me." Qin Qing raised a pure and harmless smile around her mouth, seemed to think for a moment, and said when the boy opposite was so nervous that he began to swallow his saliva: "well, in order to make classmate Zhou feel the same way, you can take an eye mask and walk around the campus."
