"This paper is specially brought for you by the school, you should cherish it. It's all big questions, the difficulty coefficient of the topic is relatively high, I haven't learned it yet, I've deleted it, these are the knowledge points that have been talked about in class, and the time has come to test whether you have listened carefully in class, whether you will draw inferences from one another, and integrate the knowledge points. Read the questions well, think hard, write well, and I will talk about every question in this paper."

"Don't doze off, some students, after physical education class, the energy is about to run out, and the head is going to hit the table. Cheer up."

"Song Yimian, I know that you study well, but now you write the questions well, this volume is not something that can be bought casually." The chemistry teacher spoke bitterly, and waited for Song Yimian to clean up the table before lowering his head in satisfaction and continuing to do his own thing.

It was the chemistry teacher who lowered his gaze again, and Hong Xiqi couldn't wait to lean back, holding the paper and looking back and forth, "I'll go, Xu Qianfeng's paper, the school has a good relationship." As I spoke, I was stunned by the first question."

"Eh, come back." Hong Xiqi skillfully unfolded the scroll in front of his head, "Mrs. Shi let you go so easily? She believes whatever you say, and she doesn't even call your parents to come and beat you? Is this the privilege of a good student? I want it too."

Tao You thought of being in the office just now, pouted and said, "I guess it was Song Yimian who let us go so easily."

"Ahem, ahem." Hong Xiqi's tablemate suddenly coughed violently, and kicked Hong Xiqi's calf.

"What?" Hong Xiqi kicked back in the next second, and his head didn't show out from behind the roll, so he whispered back, "This is a cold? The physical fitness is so poor, the napkin is inside the table, take it yourself. Remember to give me back two packs tomorrow."

「...... Ahem, ahem, ahem!" Hong Xiqi coughed more violently at the same table, and there was a posture of coughing up the whole lung, and the movements under his feet did not stop.

Hong Xiqi was kicked in a hurry, put down the roll and looked up and glared, "Your uncle, can you .......?"

Before she finished speaking, she met the half-narrowed eyes of the chemistry teacher, and the look seemed to say: I will look at you quietly to see when you will find me.

She didn't know how long the chemistry teacher had been looking, but at least she had seen it when her table mate started coughing.

Hong Xiqi's face at the same table was flushed, stroking his chest that was slightly painful because of the violent cough, he couldn't help but roll his eyes, he was about to cough and vomit, this eldest sister hadn't reacted yet, and she knew that she wouldn't work so hard.

Hong Xiqi's arrogant anger was automatically extinguished in an instant, he shrank his shoulders cowardly, turned to face his empty table, put the paper on his lap, and made a gesture to write a question.

She didn't have much time to think about the second question before she couldn't help but look up at the lectern table.

「......」

Hong Xiqi, who was looking at the chemistry teacher again, bit the tip of the pen, turned her eyes away weakly, and then glanced back again, and when she saw that the chemistry teacher was still staring at her, she grinned innocently.

"Hong Xiqi, how much time has passed, how many questions have you done? Will it be done? Look at the classmates next to you, who isn't hurrying to write the questions." When the chemistry teacher saw Hong Xiqi's "harmless to humans and animals" smile, his eyelids jumped fiercely, "Hurry up and write the question." Everyone else, pay attention, what little actions you are doing down there, I can see it clearly."

「......」

Not long after, when Tao You was desperately stumbling on the topic, a slight page turning sound sounded next to him.

The pen that was writing and drawing on the scratch paper paused, and he looked sideways at Song Yimian's overfulfilled task, and then looked at the paper that he hadn't even finished half of the teacher's request.

She just looked down at the kung fu of her paper, and saw Song Yimian scribbling a line of formulas under the question, plus an answer, and moved on to the next question.

Tao You closed his mouth in the shape of an 'o' with his hand, and glanced at the scratch paper with white flowers and no drops of black ink on the corner of the table.

Co-authoring scratch paper is an ornament here for Song Yimian.

It turns out that the real big guys do direct mental arithmetic.

No wonder Song Xiao'an's room always has such a thick stack of scratch paper, and there is always a lot of it, like cooking rice, it will reproduce by itself.

In the next second, Song Yimian closed the paper and put it aside, took out the math workbook from the table and began to write math problems in a bright manner.

"You, don't write the rest of the questions?" Tao You was curious and asked in a low voice.

Song Yimian gave her a faint look, and the words that came out could make people angry, "The topic is too simple, it's not interesting."

「......」

Too simple?

Boring?

Listen, listen, is this like a word?

Tao You felt the corners of his mouth twitch uncontrollably twice, and he was speechless for a while, and even heard the angry and beautiful language at the back table.

"This ...... Is it easy?"

"......" Song Yimian didn't speak, just glanced at Tao You very calmly, and then glanced sideways at the paper she had only written half-written, and finally withdrew his eyes, the whole process only took a few seconds, but Tao You felt that he had expressed a lot of things.

Seeing that Song Yimian had been ignoring the answer since he came back from the office, Tao Humor pushed the paper to the middle of the table, casually pointed to the question that had not yet been written, and asked tentatively, "I don't know this question, can you tell me about it?"

Song Yimian slowly wrote down a number on the exercise book, and then turned his head to look at the scroll handed over by Tao You.

With just one glance, he pulled out the blank paper at the corner of the table, neatly wrote a few lines of formulas and answers in the upper left corner, and then pushed them to Tao You.

"......" is over, and this is directly sent to a few formulas.

Tao You slowly pulled the scroll back, preparing to study it again.

Before she could move the scroll in front of her, she was pressed down by Song Yimian with a palm.

「？」

Song Yimian seemed to be looking for himself to go down the stairs, but his tone was still very cold, "Give you a lecture." If you think to yourself, you won't be able to get out of class."

「...... Look down on whom." Tao You puffed out his cheeks angrily and muttered quietly.

Well, what he said also makes sense, and I can't refute it myself.

He's amazing, he's in charge.

In the next second, Tao You persuaded himself well and listened carefully to Song Yimian's lecture.

"Okay, I know how to write it later, no need to talk about it, thank you." Halfway through the question, Tao You felt that his thinking had been completely cleared, and pushed Song Yimian's hand away, "You write your homework."

Surname. Tool man. Yi Mian, "......"

He watched Tao You take the scroll back in a daze, and took the draft paper away, and was instantly laughed at, and the two thin lips opened and closed, opened and closed.

After repeating it a few times, after realizing that Tao You really paid all his attention to that question, he turned back angrily to write his homework, but the strength of the pen seemed to be about to puncture the original homework, and his mouth kept muttering, "Next time I will give you a lecture, I will be your grandson!"

"That's not going to work," he realized what he had said, and was stunned for a moment, and then explained to himself, "It's not okay. Next time, I'll tell you a different approach, it's the most rare and complicated!"

"What did you say? Isn't it cursing?" Tao You heard Song Yimian's muttering all the time, and approached curiously, and saw his mouth squirming, and heard a few words similar to "grandson", and she fully suspected that he didn't say anything good.

「...... No, I didn't say anything, you heard me wrong." Song Yimian was stunned for a second, perfectly showing what it means to change face.

Three consecutive denials, if there is really nothing to be abnormal. Tao You half-narrowed his slanted eyes, stared at Song Yimian's face for a while, and didn't see any change in his complexion, and then tried several times without warning, and found that the result was still the same......

"Alright, stop." The chemistry teacher glanced at his phone and stood up, "It's time, it's okay if you don't finish it, I'll talk about this paper first." As he spoke, he pulled out a densely written volume with red and blue pens from under the many volumes.

"Exchange corrections at the same table. want

Calculate the scores, change them carefully. If there is a different way to do the question, raise your hand and say."

"Score? It's over, it's over, it's over, half of me is blind, and after that, how much is left?"

「...... This teacher doesn't cheat people. You'll give it to me in a moment, well, you know."

"Put some water, put some water." Hong Xiqi also winked at the same table, and then took the lead in putting a black pen wrapped in a red shell in his hand.

Hong Xiqi's table mate also took out the special black pen from the pencil case very respectfully, "I am familiar with this business, and I am wrapped in it."

"That, at the same table," Tao You smiled flatteringly as he handed over the roll, "Can you ......?"

"No, no, no." As soon as Tao You spoke, Song Yimian guessed what she was going to say, and refused solemnly, "That's cheating, how old are you and still cheating, no, if this is a formal exam, only if you make a mistake now, you won't do it next time."

"......" Tao You glared at Song Yimian hatefully.

Since she was at the same table with him, she almost forgot the refreshing feeling of changing each other at the same table and getting a perfect score every time.

It's not that she didn't dare to say it to Song Yimian, but she felt that when she said this to him, she always felt guilty about insulting his big guy temperament.

"It's all exchanged, then I'll start talking, take notes." The chemistry teacher picked out several different colors of chalk from the chalk box, broke them off, and wrote the serial number of the question on the blackboard, "Every step I talked about must be missing, and if there is one less one, points will be deducted, and they will be changed carefully."

One less point deduction?!

Heaven is a good reincarnation!

Thirty years in Hedong, thirty years in Hexi!

Wonderful!

Tao You's eyes lit up when he looked down at the scroll, and the moment he looked up, he met Song Yimian.

"Well, ahem, it's not impossible." Song Yimian looked at Tao You meaningfully in a consultative tone, "Once in a while...... It doesn't hurt." You're right.

- can still wait until Song Yimian is so angry and takes the initiative to beg her to do such a bad thing.

Suddenly, Tao You did not have the slightest sense of discomfort.

She crooked her lips and pursed her lips, shook her index finger from side to side, her expression was a little proud, she raised her eyes slightly, and looked at her as if to say, 'You also have this day, I caught you.'"

"No, no, no." She gave the three words back to Song Yimian as they were.

"That's cheating, you're the first in the grade, and the first in the grade is actually cheating?! How can you take the lead in setting such a bad example, so many pairs of eyes in the class are staring. No, if it's an official exam, you can only correct your mistakes now, and you won't do it next time."

"It's all for your good~"

Song Yimian listened to this sentence, which was not much different from what he said two minutes ago, and really wanted to smoke his two big mouths two minutes ago, and half an hour ago, he confidently and casually wrote the correct answer on the paper.

As the teacher put down the pen on the blackboard, Tao You shook the red pen and drew a bright red and conspicuous "⍻" symbol on the white and neat scroll, the whole process is so simple that it couldn't be simpler, just wait for the teacher to give the final grading criteria.

Looking at the paper, there was more than half of the extra blank space under each question, Tao You shook his head regretfully, "Tut-tut, it's a pity that so many places are empty, how good it is to write the problem-solving process or something."

"Xiao Song," she put her hand on Song Yimian's shoulder and patted her twice in a deep manner, "You, no, I didn't listen carefully in class, how many times has the teacher emphasized it, the process of solving the problem is very important, even if you write a few more formulas, you can get a few more points." You're ...... It's hard for me to do it, I can't give it points."

"......" Song Yi silently glanced at Tao You, shrugged her shoulders and shook her hand off, then turned back and drew a big red cross next to her almost full-written solution process.

Deducting a full fifteen points mercilessly, Song Yimian glanced at Tao You sideways again, and sneered silently with some provocation.

「.....

.」 Tao You looked at the three arrogant characters of '-15", and his heart was broken.

She withdrew her hand in embarrassment, and when she saw Song Yimian's sarcastic expression, her heart suddenly became unhappy, "I didn't write my first chemical formula wrong! You can't deduct all the points! At least, two points?" She shuddered and held out two fingers to discuss.

Song Yimian changed the red pen in his hand unhurriedly, and he didn't hear Tao You's words.

"One point? Zero, zero-five?" Tao You thought that he wanted too much, and held the ashes of the last bit of hope, "Didn't the teacher write like this, what's wrong."

Song Yimian finally moved.

Tap the end of the pen next to the formula three times, "Look carefully. Is this a formula? Don't look at the father as the son, these two chemical elements are different."

"......" Tao You had nothing to refute, turned around silently, bowed his head and took it seriously, and read the only concise chemical formulas he wrote on Song Yimian's volume word by word, and he was bound to find a mistake.
