They all say we're grudges

Most likely because he was still concerned about his status as a teacher just now, he didn't use up all of Yu Linyan's life skills, but now facing Zhou Xun, he threw the remaining few skills on him.

But Zhou Xun had long been used to it, and didn't respond much.

"...Forget it, let's not talk about you," Yu Linyan sighed, and took out a stack of A4 papers from his drawer, "The extra homework I prepared for you will be handed over to me in a week."

Zhou Xun took the paper and then froze.

There are about a dozen sheets of A4 paper, all of which are hand-copied topics, neatly written, and the handwriting is also pleasing to the eye.

But the problem is...

Zhou Xun fell into deep thought as he looked at the first question.

There is 25g of a mixture of NaCl and KCl, dissolved in water to form a solution, add 1000g of 7.14% AgNO3 solution, filter out the precipitate after fully reacting, then add 100g of Cu flakes to the mixture, take it out after a while (the reaction is complete), wash and dry and weigh it The mass is 101.52g, what is the amount of NaCl and KCl in the original mixture?

This……

Is it a political question?

He looked at Yu Linyan suspiciously.

"Don't look at me, I got it right." Yu Linyan didn't look at him, and said calmly, "I'm a political teacher who sorts out the science questions and doesn't let you do it, can I do it myself?"

"You are very good at politics, so you don't need to add additional topics. If you have this time, it is better to be in the ocean of reason and logic..."

Yu Linyan thought about his choice of words, and said seriously, "Plop."

Zhou Xun: "...Thank you, Teacher Yu."

"You're welcome," Yu Linyan waved his hands, "It's useless to throw yourself up, remember to call for help when you're about to drown."

"Of course, I may not hear it right away. You have to use the dog planer to save yourself first."

"Dog planing?" Zhou Xun was a little hard to understand.

"Search it on your phone, there are explanations on it, such as small x search questions, doing x help and so on." Yu Linyan looked in a good mood, so he kindly explained.

Unlike before, his soul was a metaphor for him to figure out by himself.

I can't figure it out even after thinking about it for a long time.

"... Oh." Zhou Xun nodded, indicating that he understood.

After seeing off his class representative, Yu Linyan silently took out another stack of A4 papers from the drawer. If Zhou Xun was still there, he would have found that the topics on it were exactly the same as those on his own paper.

Yu Linyan looked distressed, and muttered, "It's been a long time since I touched chemistry, what is the valence of this stuff."

He has to teach other people questions anyway, what kind of teaching is he not understanding?

Although Yu Linyan knew that Zhou Xun's science grades were definitely not bad, but he thought of Teacher Xi's entrustment and the responsibility of being a teacher in his heart, and felt that he must pick up science again.

At least Zhou Xun had to be taught something.

It was a shame and humiliation for Zhou Xun to teach him a math finale last time, and he had to find his way back.

Yu Linyan glanced at those topics and felt a little headache.

However, there are still more headaches waiting for him.

"Teacher Yu, when you were in class just now, I passed by the window of your class." The middle-aged man with glasses looked at Yu Linyan with complicated eyes, "You shouldn't conflict with the students."

"It's not a conflict." Yu Linyan took a sip of tea calmly, "At least in my heart, this level is at most his unilateral indulgence."

"...Yu Linyan, you're a teacher now, you'd better be careful when you speak." The middle-aged man sighed, took off his glasses and wiped them, and said helplessly, "It's a bit prickly to the students, besides, this way It's not good for your reputation either."

"Students nowadays, are their hearts made of colanders?" Yu Linyan looked at the middle-aged man in front of him, with a trace of annoyance on his face, "I'll be sure when I pierce it."

"...After so many years, your way of speaking hasn't changed."

"Yeah, after all, my mouth grows on my own." Yu Linyan twitched the corners of his mouth, "Principal Huang, I don't necessarily want to be a teacher, so I don't necessarily need to restrain myself."

"...Yu Linyan, before becoming a teacher, you should get to know the students." The principal sighed.

"Huh? Could it be that the family of the flirting student just now has power and power, and I, an ordinary teacher, can't afford to offend him?" Although Yu Linyan said so, there was no sign of fear on his face.

"……Yes."

"Nowadays, the rich people, except the nouveau riche, all have brains. It is impossible for me to trouble me because of this kind of thing." What can I do?"

He really didn't say anything about the student, what he said was just the truth, it is impossible for the adults in the family to take care of this matter.

The headmaster had no choice but to sigh and said, "You're right, they won't trouble you this time... But what about next time? Promise Lao Xi that you will bring this class of students to You are a sophomore in high school, don't be overwhelmed for a semester."

Yu Linyan was silent.

"Okay..." He was silent for a long time, his face changed, and finally he sighed, "I will restrain myself later."

"Lin Yan...you are no longer a student now..." the principal said helplessly.

"I know," Yu Linyan stood up and said a little irritably, "So it's very troublesome."

Yu Linyan was in a bad mood.

Zhou Xun has noticed this in the past few days.

He was a little puzzled. He did the science questions he assigned to himself every day, and he didn't think it was too difficult.

Yu Linyan saw that his answer was correct, so he didn't say much, but Zhou Xun felt something was wrong.

After getting along for many years, Zhou Xun knew his temper well, and he could see through a lot.

One day, he looked at a question that had been drafted with a pencil and was about to calculate the result. Finally, he wiped off the pencil with an eraser, leaving a faint trace.

And Yu Linyan had just finished taking a shower and came out wiping his hair when he saw Zhou Xun send him a text message.

Teacher, I don't know how to do this.

Below is a picture. There are many pencil marks under the title, which I think I have thought about carefully.

Zhou Xun waited for a few minutes before a message came from there.

That was the answering process written by Yu Linyan himself. Although he only glanced at it briefly, he knew that the process was written in too much detail.

In addition to this picture, Yu Linyan also added a sentence:

The life buoy is given to you, you can figure it out yourself.

Zhou Xun: "..."

It turned out that when he said to save him, he didn't go into the water himself, but threw the life buoy...

Zhou Xun felt it was funny.

But when he saw the next message from Yu Linyan, the faint smile froze on his face.

If you haven't jumped out yet, first consider your own problems, don't say that the life buoy I gave you leaked.

The implication is that if you read the process and haven't written it out, it's because you have a problem with your brain, not because I made a mistake in the process.

Zhou Xun shook his head helplessly, and silently replied to Yu Linyan, let me take a look, and then wrote the answer with a pen.

Yu Linyan looked at Zhou Xun's reply, and suddenly remembered what the principal had said to him.

Yes, now that I am a teacher, I have to restrain my words.

Thinking of this, Yu Linyan sent a voice chat invitation.

"teacher?"

"I think there is indeed a leak in my lifebuoy, so I'll do it myself." Yu Lin said with some reluctance on his face, but he still said so, and explained the topic to Zhou Xun in its entirety .

"Understood?" Although Yu Linyan felt that what he said was very detailed, even a pig should understand it, but he still added a sentence.

Being a teacher is really troublesome.Yu Linyan sighed.

"……understood."

Hearing Zhou Xun's answer, Yu Linyan nodded in satisfaction. Zhou Xun's savvy is what he is most satisfied with. There is no teacher who doesn't like students who can understand a little bit.

Just as Yu Linyan was about to hang up the phone, Zhou Xun stopped him.

"Teacher, have you...are you in a bad mood recently?"

"No..." Yu Linyan was slightly stunned. He didn't know how Zhou Xun could see it, but even if it was the truth, he couldn't admit it. "I tease you students every day, what's wrong with me?"

"...You're just in a bad mood." Zhou Xun's tone suddenly became serious, with a certain meaning.

"...You make me think that you know me very well." Yu Linyan clicked his tongue.

Zhou Xun was silent.

He also thought so in his heart.

"Zhou Xun, let me ask you a question," Yu Linyan seemed to think of something, "Do I think there is something wrong with the way I speak?"

Zhou Xun: "..."

Is it your soul metaphor, or the soul lecture mode.

Yu Lin said that politics can be regarded as clear and coherent, but when it comes to science subjects, it is...

"It can be seen from the title that these conditions..."

"Bring them into this formula..."

"Calculate... the answer will come out?"

"Understand?"

If it wasn't for Zhou Xun who would have known it, he really couldn't keep up with Yu Linyan's train of thought.

"...Why don't you talk?" Yu Linyan frowned, "You don't need to fool me with those lies."

"Teacher," Zhou Xun paused, "Which area are you referring to?"

which aspect?

Yu Linyan was a little annoyed. There are many other aspects of this kid's dissatisfaction with him?

"It counts."

Zhou Xun heard the annoyance hidden behind these two words. He considered his words and said, "This is Teacher Yu's personal style. In fact, you don't have to care too much about what others think or think."

"I'm asking what you think, of course I know there's no need to care about it," Yu Linyan said with a cold snort, "Can others control me?"

Zhou Xun: "..."

It's true...it can't be controlled.

"Why did the teacher ask me this?"

"Just ask casually. If you don't want to talk, go to bed early." Yu Linyan looked at the time and found that it was not too late. He suddenly felt that he was a fool, chatting with his students in the middle of the night...

Also talk about this issue.

Yu Linyan was about to cut off the call when he heard the voice of his class representative from the other end.

"Teacher Yu is very nice, I like it very much."

Zhou Xun secretly picked up some private goods, and said what he hadn't vomited for many years.

Can……

The next second, the call was cut off.

Zhou Xun looked at his darkened phone helplessly, and said goodnight softly.

like……

Yu Linyan looked at the screen of his mobile phone, his finger trembling when he pressed the hang up button.

"Say something that will be misunderstood..." Yu Linyan rubbed his hair irritably and muttered.

Just now when he heard that sound of liking, his heart was inexplicably joyful...

This emotion seemed to emerge from the bottom of my heart, suddenly, without any warning.

How is this going?

Yu Linyan frowned, feeling more irritable.

The author has something to say:

The topic comes from the Internet, the author is a liberal arts major, chemistry has long been returned to the teacher_(:з」∠)_
