Chapter 48 Milk for the Brain
Accompanied by the ringing of the bell, Shi Yun hurried in, with a thin layer of sweat on his forehead, his face was slightly red, and his chest heaved and heaved due to shortness of breath.

"Give."

Hearing Shi Yun's voice, Zhou Yisui raised his head subconsciously, and from the corner of his eye, he saw a bottle of milk on his desk, with the residual warmth of Shi Yun's palm still on the bottle.

She put it down and returned to her seat, followed by the physics teacher Chen Ting, standing on the podium.

Zhou Yisui withdrew his gaze, and moved to the milk bottle, on which was a pink post-it note: Milk nourishes the brain, cheers at the end of the term!
Her handwriting is very delicate and special, unlike any typeface on copybooks, the force is very light, and the two strokes are simple to draw, and the shape is true to life.

Zhou Yisui tore off the post-it note and pasted it on the table next to the green paint.

He flicked the sticky note lightly with his fingertips, and landed on the green paint again.

At first, Yun didn't understand why he chose a table with dirty things on it. If you look carefully, the pattern looks like a person's back.

You only need to add a few strokes and mold a shape, and a delicate figure will appear on the table.

However, Zhou Yisui lowered his eyelashes, he didn't add those two strokes, they only existed in his mind.

"This is a question that combines magnetic and electric fields. Zhou Yisui, right? Can you tell me what the electric field strength E0 is at this time?"

Following Chen Ting's voice, most of the people turned their eyes to the back, and a few of them suppressed the corners of their mouths, full of gloating.

The person who was called back to God by his own name stood up unhurriedly, looking at the topic on the ppt with calm eyes.

Just now Chen Ting talked about his ideas on the above, if you follow along, you will be able to figure out the answer in a while.

Shi Yun tilted his head to look at him, and the hand holding the pen couldn't help sweating a little sticky.

After half a minute, he still remained silent, not even writing to calculate.

Just when Chen Ting thought he couldn't solve it, Zhou Yisui said: "E0=mv0/qt0."

The hand that had just been raised to make him sit down paused, and Chen Ting continued to ask: "If the charged particles move to the point where they can return to the original point, what conditions should the electric field strength E satisfy?"

“（2n+1）mv0/3nqt0（n=1，2，3）”

Chen Ting raised the page presenter in his hand and tapped it, the answer was displayed, and everyone sighed.

He said with satisfaction: "Yes, the answer is yes, but there is one more question—"

"It didn't say whether the magnetic induction intensity is equal or not."

Zhou Yisui spoke out the problem of this question as if he was cooperating with him.

Chen Ting found it very interesting, "When we usually do the questions, we often ignore this point and always subconsciously think that the magnetic induction is the same, but this is often a pitfall. Of course it is not this question. We have to consider, if It is two magnetic fields with different magnetic induction intensities spliced ​​together, then we should pay attention to separate calculations."

After saying these words, Chen Ting's eyes shifted to Zhou Yisui again, and he couldn't help asking, "Did you transfer here not long ago?"

"Yes."

"Where did you go to school?"

"Longshui Zhengyang Town."

As soon as Zhou Yisui finished speaking, he saw Chen Ting's expression was a bit subtle.

"I went there 20 years ago to support education." Chen Ting waved his hand and asked Zhou Yisui to sit down, "It was summer when I went there, and what impressed me the most was a river, it seems to be called Hongguang River, right?"

Shi Yun turned his head to see Zhou Yisui's eyes darkened when he heard the name, as if he had returned to the state some time ago.

Before Chen Ting could recall the past, the get out of class bell rang.

Cao Jia stood at the door on time, looked at Chen Ting and smiled, "Mr. Chen, is it over?"

"It's over, it's over." Chen Ting packed up his books with a smile, canceled the screen projection, and walked towards the door with his notebook, "Are you watching me finish class?"

"How can it be? It's not that they went crazy and disappeared as soon as the get out of class was over. I still have something to say, so I have to block them."

"Understood, you are busy!"

There was commotion in the classroom, whispering to each other, Cao Jia coughed and walked in, "Take up a little time for everyone to talk about the final exam."

There was cheering from below.

"Shouldn't you be worried about your grades?" Cao Jia opened the notebook in his hand, talking about the exam arrangement and precautions one by one.

After scanning around, his eyes fell on Zhou Yisui, and he said, "Zhou Yisui, because this is your first exam and you have no previous grades, so I arranged for you to be in the last exam room."

"Ah."

"Okay, there's nothing else to do. You can go home after the exam tomorrow, and stay at home for the past two months." Cao Jia instructed, "Don't forget that there is still a basic exam when you come back."

"Ah—" the audience screamed.

Cao Jia was amused by them, "I really think you should go to a film school, because heaven and earth let you act."

"Hahaha——" Han Ling's voice was very penetrating, and her laughter broke through the crowd.

She said: "Teacher, you don't understand this, right? The film school is not only looking at acting skills, the most important thing is appearance! We have to consider whether the film will affect the appearance of the city."

"It's the teacher, there are only a few good looks in our class!" Xu Heng echoed.

Cao Jia glanced at those good looks and nodded with satisfaction, "You see, there is another way to go, and those who are still working hard are still studying hard. What reason do you have for not studying?"

Shi Yun looked at the messy and dirty paper under his palm, and was extremely ashamed when he heard this sentence.

When Cao Jia left, Shi Yun breathed a sigh of relief, the chair was suddenly kicked off, and she looked behind.

Xu Ye leaned on the back of the chair like an old man, raised his lazy eyes, as if he wasn't the one who kicked her chair just now.

"Milk!" His tone was not as calm as his expression, and he was a little angry.

"What milk?" After speaking, his eyes fell on Zhou Yisui's table, his head grew big, "You want to drink too?"

He looked as if it should be taken for granted, "Why, can't you?"

"But aren't you lactose intolerant?" Shi Yun accidentally met Zhou Yisui's gaze when he was looking at the bottle, and then avoided it resentfully, "You can't drink that milk."

"I want it!" He acted like a hooligan.

Zhou Yisui got up suddenly, the sound of chairs rubbing the floor interrupted the conversation between the two, under their gaze, Zhou Yisui left the classroom.

Shi Yun looked at the sun hanging high outside, then stared straight at him again, "Are you sure you want me to buy it for you under the sun?"

Xu also can't listen to soft words, and his heart softens when he hears them.He can't listen to hard words, and he gets angry when he hears them.

Just when the two of them were unwilling to say anything more, Zhou Yisui walked in with the residual heat of the sun, and placed two bottles of lactose-free pure milk on Shi Yun's table.

Shi Yun raised his head and looked at Zhou Yisui who sat back to study after silently finishing the work, his cold white skin was a little flushed by the sun, and unconsciously moved his eyes down a little, and landed on his lips superior.

The color of his lips is very light, probably because the color of his whole face is too light, so it makes his eyes very dark, which makes people like it.

　Shi Yun: Let me really like it
　　Joe: Study hard and make progress every day, otherwise you will not only have no love, but also no good grades.You see Xu is an example.

　　Xu Ye: Thank you, my family is rich.

　　(The title piece was made up by me, so don’t be particular about it, thank you~)
