In the five-kilometer run, Shen Yiyun finally refused.

After dozens or hundreds of weight loss actions, Shen Yiyun has already had a clear understanding of himself.

Take the last time, I ambitiously bought 2000+ worth of running clothes and running shoes, only wore them once, and now they are still hanging on the balcony.

After that, in order to sell the idle fish, I struggled to this day.

In the meantime, in order to treat himself, he secretly went to eat three meals of Xiabu.

Today, she has fully realized that losing weight is financially, energetically, and emotionally negative.

In this way, after reconciling with his figure, Shen Yiyun's whole person also became confident.

She and Li Zheng were walking on the street, raising their glasses angrily and chatting eloquently.

In other words, having a slightly plump physique like me is actually a genetic advantage. ”

"In the era when food was not abundant, it was possible to absorb nutrients and store energy more efficiently. ”

"It's only because human society is developing too fast and the food is too abundant that there is a little bit of fat now. ”

"Looking at the history of human development, such an era is actually very rare. ”

"Hmph, once something happens like a zombie apocalypse, I can last three days with one meal, and then those thin people will be too late to envy me. ”

Shen Yiyun said and glanced at Li Zheng: "It's a waste of energy to run five kilometers! The entropy of the universe has been raised so meaninglessly by you." ”

"So......" Li Zheng looked at the plaque of the Jida Academy not far away and said, "Is your choice of chemistry just to cause the zombie apocalypse?"

"Hey, sister's project scares you to death when she says it. Shen Yiyun snorted and laughed, "Are you ready?"

"Listen to ......"

"Chlorine replaces organic photovoltaic material design. ”

"Hmm...... It's quite powerful......" Li Zheng rubbed his cheeks and said, "I can probably feel the direction, which is to optimize the process of organic photovoltaic material synthesis, right?"

"Hmph, that's fine, specifically, it's to replace the fluorine atom in the benzodithiophene polymer PBDB-TF with the chlorine atom, PBDB-TF you may not have heard of, it's ......"

This scene of hard-core chemistry discussion is very normal between Li Zheng and Shen Yiyun.

But from the perspective of passers-by, there is a strong shock effect.

In general, with the opposite sex, so hard to talk about scientific research...... No matter how you think about it, it's something that only a straight man of steel can do.

Now it's a little fat glasses girl doing it.

And beside her, who seemed to understand at all, but pretended to understand and nodded frequently, it was a top beautiful man.

What is this, "My Object is a Straight Female Scientist"?

Passers-by looked at the young and strong Li Zheng, and then at Shen Yiyun, who had excellent genes.

It's not easy, young boys now.

Li Zheng and Shen Yiyun entered the School of Chemistry, chatting about this topic all the way into the building full of laboratories, and came to the Polymer Materials and Scientific Research Laboratory.

This is Li Zheng's first time entering the scientific research laboratory, and his first feeling is-

Disorderly!

A row of tables, like a machine station, chairs of different styles, as well as a variety of pillows and potted plants, the table and the floor are also full of materials and sundries.

Among them is a table piled high with snacks and a row of nutrition fasteners.

"Senior sister, are you still drinking this when you're so old?" Li Zheng couldn't bear to say, "This is for children to grow their bodies......"

"How do you know this is my desk?"

"Isn't it obvious......" Li Zheng walked to the table, looking at all kinds of pots, Langwei Immortals or something, and he didn't dare to say anything.

"Don't touch my snacks. Shen Yiyun stepped forward vigilantly and stuffed a set of experimental equipment to Li Zheng, "Don't look here, go inside." ”

"Oh......"

The two changed their clothes, passed through a glass door partition, and their vision was instantly brighter.

Unlike the outside, the inside is spotless, clean and bright.

The three rows of long tables are covered with things that Li Zheng has seen and has never seen, just from the appearance, he knows that they are high-grade goods, and the experimental examination equipment is incomparable with here.

Li Zheng stepped forward with longing and stroked a white square instrument that looked like a large printer.

Shen Yiyun hugged his chest and smiled: "This, the new Agilent ion trap mass spectrometer, I will have time to try it for you in a while." ”

"I ...... Is it okay......" Li Zheng blushed and walked to the front of the instrument.

I'm not going to touch chemistry anymore.

But why, there is an itchy feeling that is faintly haunting?

Could this be the ......

My seven-year itch with physics?

Although I am preparing for the physics competition with all my might, this string has been broken for too long, and it is inevitable that I will be a little numb.

At this time, I suddenly encountered a bewitching chemical instrument outside......

Brand new equipment, top-of-the-line texture, mysterious effects, completely unknown to start this guy, what will happen in the next second.

It's a little unbearable......

"Do you know this?" Shen Yiyun walked to a barrel-shaped instrument made of steel, "The high vacuum purification system for organic small molecule materials is purely domestic and very easy to use." ”

"Don't ......," Li Zheng swallowed and foamed, "Don't say it again...... I'm a high school student, so I shouldn't touch these high-end devices......"

"Hey, what's this. Shen Yiyun laughed and said, "Today's holiday, the laboratory is your sister and mine, just play casually." ”

Before she could finish speaking, a slightly hoarse male voice suddenly came from the innermost part of the laboratory: "Oh?"

Shen Yiyun trembled instantly: "Hu ...... Teacher Hu......"

Li Zheng was also trembling and stood up in a panic.

The two stared at the corner for a long time, only to see a middle-aged man with "compensating for the inch" slowly getting up, with a straight face, and swept towards the two expressionlessly.

Compensating for the inch is a concept invented by Li Zheng temporarily.

Generally speaking, the number and length of hair of men who have learned well before the age of 20 are very different.

But after the age of 20, this changes.

About 79% of students learn to have a good hair, and the number of hair will gradually decrease.

In order to curb this trend, they have to increase the length of the hair to compensate, so that the number of hair X the total average length remains the same, so as to achieve the effect that the total hair volume remains the same.

The middle-aged man in front of him is a "compensator" with about 68% compensation, and he did use the raised length to cover a considerable area of lost hair, achieving an effect that seems to be on the verge of baldness.

Li Zheng has already observed this situation, so naturally he is not too panicked, and it is already difficult to hold back these observation experiences and not share them.

It was Shen Yiyun who was already scared.

Teacher Hu...... This is...... It is...... At that time, Huajing asked me to help with the training......"

"I remember, Li Zheng. He stared at Li Zheng for a moment with a calm face, then turned to look at Shen Yiyun, "Who allowed him to come in?"

"I ...... I'm ...... I'd like to ask him to watch IChO with me...... Just a good time to visit ......"

"Visit?" he nodded the table and asked with cold eyes, "Is he a leader of the Ministry of Education or the Ministry of Science and Technology?" Has the visit been registered? Who is responsible for the safety problem? Who is responsible for the leakage of scientific research results? Do you know how many regulations you have violated?"

"Let's get out...... This is going out...... I'm sorry Mr. Hu......" Shen Yiyun pulled Li Zheng and fled out.

Li Zheng knew that he was at a loss, so he apologized again and again, and left the experimental area with Shen Yiyun.

Out of the partition, Li Zheng said embarrassedly while taking off his coat: "I'm sorry, I'm sorry...... I got carried away. ”

"No, no, no, blame me...... It's me who got carried away......" Shen Yiyun pushed Li Zheng and said, "You wait for me here first...... I went in and was scolded. ”

"I'm also at fault, I'll be scolded with you. ”

"Don't! Have you forgotten how much he hates you?"

"Huh?"

"Hu Zengwu, have you forgotten?"

"It's familiar......" Li Zheng thought for a moment, and then his eyes widened.

The focus is entirely on the degree of compensation, and I don't look at the face at all.

Now I think about it, isn't Shen Yiyun's mentor Hu Zengwu, the teacher who made a lot of trouble because of Wu Shu and Shi Yang's chemistry training at that time.

Why is it so inch, every time he is caught......

Li Zheng is okay, just admit his mistakes sincerely.

But Shen Yiyun was adamant that Hu Zengwu would only be more angry when he saw Li Zheng, so he could only prevent him from appearing again, and went in alone to scold.

Li Zheng was not easy to argue, so he quickly changed out of his experimental coat and escaped into the corridor, waiting for the results of his senior sister's treatment.

This wait, not long.

Soon, Hu Zengwu came out with a straight face.

Shen Yiyun followed behind timidly, his face full of embarrassment.

Before Li Zheng could say anything, Hu Zengwu had already spoken.

"Yiyun said, you heard that she is very busy here, and offered to help do some basic experiments?"

Li Zheng's eyes widened.

Do I have it???

Soon, he received Shen Yiyun's pleading look.

So it's pretty clear.

Shen Yiyun shouldered all the sins on the surface.

In fact, he just isolated Li Zheng outside, so that he could fully shake off the pot.

Okay, you senior sister, I didn't expect you to be able to do this kind of thing with thick eyebrows and big faces!

Li Zheng's face trembled with anger, and he immediately lowered his head: "Yes, Mr. Hu, I proposed to help myself...... I'm sorry I didn't take into account the rules and regulations of the laboratory. ”

"You don't think about the rules system, I believe it. Hu Zengwu shook his head and said with a dry smile, "It's just that you can't help but think about scientific research experiments too simply, there is still a long distance between high scores in competitions and real experiments." ”

"Yes......" Li Zheng bowed his head and said.

"You don't have to be like this, I'm not training you, and I'm not your teacher, so I'm not qualified to discipline you. Hu Zengwu turned his head and said, "No matter what the reason for this incident is, the responsibility lies with Shen Yiyun, there is a precedent for someone to bring a child into the laboratory to cause an accident before, and even some people bring their boyfriend and girlfriend in, and in the end they are found to be spies, which is by no means sensational." What you have in mind is your business, and Yiyun agrees that it's her business. ”

Shen Yiyun lowered his head, and his mouth was already trembling.

"Luckily, we're not a secret project either. Hu Zengwu tilted his head and ordered, "Give Li Zheng a few sets of relevant papers, as well as the basic experimental process, if he can read it, he can go in and try it, and don't delay time if he doesn't understand." ”

"Ahh

"Bow your head and be willing to be a son of a cow? Hu Zengwu snorted and said, "Although the competition is long from the scientific research experiment, as far as I know, Shi Yang has already gone to Dean Zhou's laboratory to help, and for some people, this distance may not be that long." ”

Li Zheng also trembled, "Thank you, Mr. Hu, I am reading the thesis." ”

"Don't get excited. Hu Zengwu replied with a sneer, "I just want to tell you that you may not be those people, don't speak wildly next time." ”

After that, he turned around and walked to the laboratory: "After Yiyun gave the information to Li Zheng, come in to help." ”

"Ah...... Isn't it a holiday today......"

"Vacations?

“...... No...... No...... I'm here ......."

After Hu Zengwu went in completely, Shen Yiyun stuck out his tongue and pulled Li Zheng back to his desk.

"It seems that the progress of the experiment is really ......tight," Shen Yiyun smiled bitterly, "Mr. Hu saw that Dean Zhou had made an exception to let Shi Yang into the laboratory, and he also wanted to take advantage of the high school students who were idle and had nothing to do......"

"No, I'm short on time. Li Zheng scratched his head and said, "And what do I think, he just wants to see that I can't read the paper and scare me away." ”

"Hey, it doesn't matter, it's impossible to see it in a day anyway. Shen Yiyun said and opened the file cabinet in the corner, "You just look at it twice, and then say hello and say you don't understand, just withdraw, I'll give you the contact information of a senior brother at that time, you go to him, and we'll watch the closing ceremony together at that time." ”

She said very casually, but Li Zheng had already put down his schoolbag, took out a pair of stationery that was originally going to deal with the competition training, and put it on the table properly.

After preparation, Li Zheng sat at the table, moved his fingers and said, "I remember that the core is to enhance the intramolecular charge transfer effect by introducing dichlorocyanonindione as an end group, right?"

Shen Yiyun flipped through the information and sighed: "Ah...... Be...... What a good memory......"

"I haven't turned chemistry in the past few months, and it's a long way off. Li Zheng intertwined his hands, pushed forward with his backhand, stretched his tendons and sneered, "It's to make up for IChO's regrets, today, I am with Shi Yang." ”

"Lying down......," Shen Yiyun scolded, "Inexplicably, it's serious." ”

At the same time, Hu Zengwu's serious voice came from the laboratory: "Yiyun?"

"Come, come. ”

"Li Zheng can't understand it, let him go, don't delay everyone's time. ”

"Ah, Li Zheng looks very serious, let's let him try?"

"Let it be. ”

......

Not long after, Shen Yiyun had already opened three extra-long papers in the computer and sent a stack of experiment-related paper materials.

"These are the principles of application. After Shen Yiyun pointed at the computer screen, he patted the materials on the table, "These are the operating specifications and workflow of relevant instruments, and the recording specifications, if you master them all, you can basically be regarded as a scientific research assistant." ”

"I don't care about anything else. Li Zheng rolled up his sleeves, "Shi Yangquan has mastered it, right?"

"Can you enter Zhou Yi's laboratory...... I guess it'......."

"I'm no worse than him, just keep yours busy. Li Zheng waved his hand in disgust.

"Alas...... If you can't bear it, say it when you leave......"

Shen Yiyun entered the laboratory, came to the experimental table he was familiar with, and silently prepared the experiment that had been operated thousands of times.

In order to figure out a principle and optimize a process, it is usually necessary to go through thousands of repetitions, and then change a variable or condition, and then come back tens of millions of times.

It's been a long time, it's grinding, but it has to be done.

During the preparation, Hu Zengwu asked without a match: "I heard you just say that he originally came to the competition for training, but then he felt bored and left again?"

"It seems to be. ”

"Muddy the waters of chemistry training and mess with physics again. Hu Zengwu pursed his lips and said, "It must be difficult for the training teacher to do." ”

"Hmm...... I don't know why this training camp is to solve its conflicts...... Hearing that Li Zheng was leaving, he seemed to be quite happy. ”

"Oh, okay, the flies look at the mung beans, and they actually meet each other's eyes. Hu Zengwu rarely laughed, "People who don't pay attention to the rules and are in a hurry can only achieve nothing no matter how good their brains are......"

"This ...... Teacher Hu, Li Zheng is actually quite down-to-earth. ”

"Whether you are down-to-earth or not is not something you see, you do. Hu Zengwu pouted outside the laboratory, "If he can sit until we get off work today and study seriously for seven or eight hours, he will be able to be considered down-to-earth and have room for remedy." ”

Hu Zengwu's voice just fell.

A cold and beautiful man in a white lab coat had stepped into the laboratory with his hands raised.

"I'm all right. ”

He nodded.
