After five kilometers of running, Shen Yiyun finally refused.

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

Take last time for example, I ambitiously bought running clothes and shoes worth 2000+, which I only wore once and are still hanging on the balcony.

After that, I debated whether to sell Xianyu or not to this day.

In order to reward myself, I secretly had three Xiabu meals.

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

In this way, after coming to terms with his figure, Shen Yiyun became more confident.

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

"In other words, having a slightly plump physique like mine is actually a genetic advantage."

"In an era when food is not abundant, nutrients can be absorbed more efficiently and energy can be stored."

"It's just that human society has developed too fast and food is too plentiful, which leads to a little bit of obesity now."

"Looking at the history of human development, such eras are actually very few."

"Hmph, if something like the zombie apocalypse happens, I can last for three days with one meal, and those skinny people won't even have time to envy me."

Shen Yiyun glanced at Li Zheng as he spoke: "Running five kilometers? A waste of energy! The entropy of the universe has been increased so meaninglessly by you."

"So..." Li Zheng looked at the plaque of Ji Dahua College not far away and said, "Is your choice of chemistry just to trigger a zombie apocalypse?"

"Hey, my sister's project will scare you to death." Shen Yiyun chuckled, "Are you ready?"

"All ears..."

"Chlorine-substituted organic photovoltaic materials design."

"Hmm...it's quite impressive..." Li Zheng rubbed his cheeks and said, "You can probably feel the direction, which is to optimize the synthesis process of organic photovoltaic materials, right?"

"Humph, that's great. Specifically, it replaces the fluorine atoms in the benzodithiophene polymer pbdb-tf with chlorine atoms. You may not have heard of pbdb-tf, but..."

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

But from the perspective of passers-by, it has a very shocking effect.

Generally speaking, being with the opposite sex and talking about scientific research are things that only straight men can do, no matter how you think about it.

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

And next to her, who seemed to not understand at all, but pretended to understand and nodded frequently, was actually a top-notch handsome man.

What is this, "My partner is a straight female scientist"?

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

It’s not easy for young boys today.

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

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

chaos!

There is a row of tables, arranged like office workstations, with chairs of different styles, and various pillows and potted plants. The tables and floor are also filled with documents and sundries.

There is a table piled with snacks and a row of nutrition express lines.

"Senior, you are still drinking this when you are so old?" Li Zheng said unbearably, "This is for children to grow..."

"How do you know this is my table?"

"Isn't this very obvious..." Li Zheng walked to the table and looked at the various kinds of rice dumplings, Langweixian and the like, but he didn't dare to say anything.

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

"oh……"

The two of them changed their clothes and passed through a glass door partition, and their view suddenly became brighter.

Unlike the outside, it can be said to be spotless, clean and bright inside.

The three rows of long tables were covered with things that Li Zheng had seen and things he had never seen before. Just from the appearance, it was obvious that they were top-notch goods. The experimental and examination equipment was incomparable to those here.

Li Zheng walked forward full of longing and gently touched a white square instrument that looked like a large printer.

Shen Yiyun crossed his arms and said with a smile: "This is a brand new Agilent ion trap mass spectrometer. I'll give you a try later when I have time."

"I...can..." Li Zheng blushed and walked to the front of the instrument.

Obviously I am no longer ready to touch chemistry.

But why is there a vague itching feeling?

Could it be that this is...

My seven-year itch with physics?

Although I am fully preparing for the physics competition, this string has been broken for too long, and it is inevitable that I will feel a little numb.

At this time, I suddenly encountered an enchanting chemical instrument outside...

Brand new equipment, top quality, mysterious effects, I have no idea what will happen next second when I turn this thing on.

I can’t stand it...

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

"Don't..." Li Zheng swallowed, "Stop talking... I'm a high school student, I shouldn't touch these high-end equipment..."

"Hey, what's the point?" Shen Yiyun laughed, "It's a day off today, the laboratory belongs to your sister and me, you can play whatever you want."

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

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

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

The two of them stared at the corner for a long time before they saw a middle-aged man with "compensating" eyes slowly stand up and glance at the two of them with a straight face and an expressionless expression.

Compensating short positions is a concept temporarily invented by Li Zheng.

Generally speaking, the hair quantity and length of men with short hair who learned well before the age of 20 are quite similar.

But after the age of 20, this situation will change.

About 79% of people learn to have a short haircut, and the number of hair will gradually decrease.

In order to curb this trend, they have to increase the length of their hair to compensate, so that the total number of hair x average length remains unchanged, so that the total hair volume remains unchanged.

The middle-aged man in front of him is a "compensated short hair" with a compensation degree of about 68%. He has indeed used the increased length to cover a considerable area of ​​hair loss, achieving a look that seems to be on the verge of baldness. Effect.

Li Zheng has already observed to this point, so naturally he is no longer too panicked. It is already difficult to hold back these observation experiences and not share them.

Shen Yiyun, on the other hand, was so frightened that he started to stutter.

"Teacher Hu...this is...it was...Hua Jing asked me to help with the training at that time..."

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

"I...I, I, I...I want to invite him to see Icho together...just for a visit..."

"Visit?" Compensation Cuntou tapped the table hard and asked coldly, "Is he the leader of the Ministry of Education or the Ministry of Science and Technology? Has the visit been registered? Who is responsible for safety problems? Who is responsible for the leakage of scientific research results? You know what you are doing? How many rules were violated?"

"Get out now...get out right now...I'm sorry, Teacher Hu..." Shen Yiyun pulled Li Zheng over and ran away.

Li Zheng knew he was in the wrong, so he apologized repeatedly and followed Shen Yiyun out of the experimental area.

After leaving the partition, Li Zheng took off his coat and said sheepishly: "I'm sorry, I'm sorry... I got carried away."

"No, no, no, blame me... I got carried away..." Shen Yiyun pushed Li Zheng and said, "Wait for me here first... I'll go in and get scolded."

"I was wrong too, so I'll be scolded with you."

"No! Have you forgotten how much he hates you?"

"ah?"

"Hu Zengwu, have you forgotten?"

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

The focus is entirely on the degree of compensation, not the face at all.

Now I think about it, isn't Shen Yiyun's mentor Hu Zengwu? The teacher who caused a lot of unpleasantness in the chemistry training camp because of Wu Shu and Shi Yang's incident.

Why is it so small, yet he always catches it...

Li Zheng is fine, he just admits his mistake sincerely.

But Shen Yiyun insisted that Hu Zengwu would only become more angry when he saw Li Zheng, so he had no choice but to prevent him from appearing again and go in alone to bear the scolding.

Li Zheng didn't want to argue hard, so he quickly changed out of his lab coat, escaped into the corridor, and waited for the senior sister's processing results.

The wait didn't take long.

Soon, Hu Zengwu came out with a straight face.
To be continued...
