Li Zheng and Lin Yuejing's entanglement is naturally seen in the eyes.

When you miss someone, you may be missed by someone else.

The premise is that you study well, or at least grow well.

And in this laboratory, the one who missed Li Zheng was just another person, Qi Yingnan.

It is Duan Peipei who is staring at Lin Yuejing.

As for the other people, they did not want to disturb Li Zheng and Lin Yuejing.

In the first place, the domain of learning hegemony is respected, and only these two individuals are eligible to become teammates of the other party.

Secondly, when the head of the class was announced, the whole class had already seen the two of them whispering and screaming, not to mention staring, not to mention that they were originally alumni and it was really inconvenient to bother.

Even Fu Xuefeng, who was busy preparing for work in front of the podium, was expecting the two to form a team soon, wanting to see what kind of sparks would be worn out.

Strictly speaking, this is also the position of Qi Yingnan.

Although the big brothers of the same group had a great conversation along the way, but after seeing Li Zheng entering the laboratory, Qi Yingnan probably knew Li Zheng's thoughts.

"Don't hurry?" Qi Yingnan bumped Li Zheng's shoulder and rushed to seize the throne of the window, Lin Yujing, who slept and basked in the sun, made a mouthful. "You're stupid if someone else sits in the first place."

Li Zheng was surprised, then sighed.

Worthy of being a big brother, understand me.

It's not because of anything else, mainly because I have never worked with Lin Yuejing for many years.

Occasionally letting go of it and learning together is also excellent.

If you can capture the student movement, it would be even better.

The only bad thing is...

"I just lost a battle, and I just passed...wouldn't I bow down and say my honor..." Li Zheng frowned, rubbing his cheeks, completely without the determination of the past.

Qi Yingnan stared at Li Zheng for a long time and also rubbed his cheek with his frown.

You... say Nima?

The 90-point thinking field is hard for ordinary people to understand...

On the other side, Duan Peipei didn't think so much.

God must be holy. How can it be related to boys?

With the blessing of faith, she walked firmly to the window and stood in the empty space beside Lin Yuejing.

But really standing here is inevitably cramped.

"Jian Jing, can I...can I have a group with you?" Duan Peipei asked, twisting his body slightly.

"Ah..." Lin Yujing raised his head from lying on his stomach, his expression a bit stiff, but could not find any reason to refuse.

Angrily, one turned his head and stared straight at Li Zheng.

Not in a hurry? !

This is another law about women. After all the annoyance, after going through the brain circuit, it will eventually fall on the man.

Not far away, Qi Yingnan saw Duan Peipei cut off Hu, and had already pushed Li Zheng to rush here.

At this time, Lin Yuejing stared at him again. Qi Yingnan simply pushed hard and pushed Li Zheng over.

Brother, just help you get here.

With the help of Qi Yingnan, Li Zheng staggered and leaned on the experimental table.

At this point, he simply crossed his heart, gritted his teeth, raised his head, tilted his body, bypassed Duan Pei Pei Chong Lin Jingjing and said: "You...you...why are you staring at me? Do you want to form a team?"

"?????" Lin Yuejing became angry and corrupted. "Do I need reasons to stare at you?"

"That's right..." Li Zheng said with a sideways panic, scratching his face. "...Come all here, or should we make up?"

"Not sincere, say it again."

"Then... let's form a team?"

"Not sincere."

"Why are you doing so many things?"

"Are you talking with scum?"

"Why am I scum?" Li Zheng glared. "I have already drawn the line with the person who should draw the line, what do you want me to do?"

"~~~"

Duan Peipei was caught in the middle of the two, and his face was pulled down in a grudge.

It turns out that the two of them have long been...

Also draw a line...

Under the multiple penetrating blows, she turned back sadly, as if she were one with Jiang Qinghua's soul, and quietly left the scene quietly.

As soon as this position was let out, Li Zheng also came across, pulled out his chair and sat down, and the raw rice was cooked.

Lin Yuejing just groaned with inertia and turned his head: "I'm experimenting...in fact, I won't..."

"Oh." Li Zheng believed that she was a ghost. "I have taken the initiative to seek cooperation. Are you still plotting to dirty me? Is it interesting?"

"No... I haven't done much."

"Just kidding, didn't you claim to be practicing in the aerospace laboratory Dongfu?"

"Actually, I've been there once... the astronauts experience warehouses or something."

"Edit, then edit."

"believe it or not."

On the other side, Qi Yingnan and Duan Peipei also placed orders because they were spending too much time on others. Fu Xuefeng directly let the two team together.

Qi Yingnan didn't have any superfluous ideas. He came here to go to the provincial team, and no one would affect his study.

Duan Peipei had no more ideas, not only no ideas, but nothing.

Because Zhang Tao took the school out of his mouth when he announced his results, Qi Yingnan also remembered Duan Peipei.

While Qi Yingnan counted the experimental equipment, he casually chatted: "Right, are you in class eight?"

"Nine shifts," Duan Pepemu replied.

"Hey, I'm sorry, I don't remember clearly." Qi Yingnan waved his hand and smiled, "That's nothing, don't fight with Li Zheng, the brains of our group are not normal, just simple neuropathy, no malicious. ."

"In the group?"

"Oh, there is a dragon ball group, who specializes in competitions." Qi Yingnan laughed and laughed at Li Zheng. "This goods has just usurped power and took the group owner, which is basically the most abnormal one, ha ha."

"Ah?!" Duan Peipei's already silent heart broke out again, and asked with glaring eyes, "You are talking about the group that collects one Dragon Ball?"

"Haha, yes, yes, I used to get mathematics before, but that was just for fun." Qi Yingnan smiled and raised his glasses. "Physics is the fate, and I came to the provincial team training last year."

"Can I still listen to the training?"

"Well, there are not many places, and it will cost money." Qi Yingnan looked at the experimental equipment. "Every time such a competition and training, the organizing committee and colleges and universities are losing money. Occasionally, some listening places will be opened. Make up for the shortfall."

Listening to these things, Duan Peipei was gradually pulled back to the mood he was supposed to train.

"This is amazing." Duan Peipei exclaimed, and suddenly remembered something, "Then, if you participated in the provincial team training last year...should you know Wu Shu?"

"I know and know, and the last group owner is also there. I was in the Dragon Ball group at that time." Qi Yingnan sighed, "I felt that in the face of the group owner, I spent one year and was still able Put it together... As for the realm of Wushu... I really can't see clearly..."

These legends also evoke Duan Peipei's interest, just as ordinary disciples listened to the master's talk about Huashan's discussion of swords.

Also, you can't help asking some gossip questions.

"Then Lin Yujing compares with Wu Shu?"

"I don't really know this. An informal examination is not enough to judge." Qi Yingnan Zhenzhen nodded. "What I know is that Wu Shu's experimental methods can't even pick out the problems of the professors. This strength even extends to chemistry. Last year, in the chemical competition last year, she didn't make up enough for her chemical experiments, so she took the national gold."

"Wow." Duan Peipei fascinated.

Under the attack of Li Zheng and Lin Yuejing, in front of the real big man Qi Yingnan, she has unknowingly put down her arrogance and became a shocked baby.

"So, Lin Yujing's degree is not good yet." Qi Yingnan crossed his arms together and stretched his arms to stretch his tendons. "One point I will declare that I started preparing for the experiment in the first year of high school. At that time, although I didn’t qualify for the competition, my experiment score was third."

"Wow!"

"So, I probably won't do experiments at the pace of Teacher Fu, and I will often play according to my own ideas, don't mind."

"Wow! Don't mind."

"Success." Qi Yingnan turned to look at Li and Lin who were fighting, narrowing his eyes. "These two products show love in the training class. Let's just study hard. If possible, kill them smoothly. Their sharpness."

"Wow!" Duan Peipei's eyes lit up. "Then I will hold your thigh."

"Not to mention, improve together."

...

The first experimental class will start soon.

Because it is an improvement class for the provincial team, the basic content is naturally skipped and the real topic drill is directly started.

Fu Xuefeng said nothing, and got a hot hand question--

[Measure the refractive index of transparent containers and liquids]

This is the most common optical experiment problem. A beam of light is hit on a cup filled with unknown liquid, a light path diagram is drawn on coordinate paper, measurement and calculation, and the answer is written.

After demonstrating + explaining the main points of the experiment, then enter the group experiment time.

Faced with this basic problem, everyone started without hesitation.

Fu Xuefeng toured all the way and saw that most people are familiar with it, and he is in a much better mood.

In the previous theoretical exams, the topics were both difficult and partial, which caused everyone to fail the exam, which made Fu Xuefeng somewhat doubt the level of this class of students.

Now it seems that it is completely over-considered. Obviously everyone has sufficient preparation, but they are just messed up by the bias, and they are really old fritters.

Especially in the Qi Yingnan group, whether it is speed, accuracy or stability, it has reached the level of the top few provincial teams in previous years.

Fu Xuefeng basically looked at everyone, and finally walked to Li Zheng and Lin Yuejing.

No way, the most delicious, always wait until the end.

Come on, let me see the 90-point field!

Although Fu Xuefeng looked forward, he did not hurry to pass from the front, but slowly approached from behind.

I have to say that he has a bit of fun, not only looking forward to their experimental results, but also looking forward to their interaction.

He did not know that the situation was far more anxious than he imagined.

Li Zheng wiped his sweat and glared and asked, "I have already listed all the formulas, can't you adjust the laser pointer?"

"No... The above said that you want to adjust to the best state. What is the best state?"

"Just be thinner?"

"It's too thin to be seen?"

"Then you can just see it?"

"Yeah... but what is it just to see?"

"No matter, let's just..." Lin Yuejing began to fix the laser pointer on the test stand. "Is this how it is screwed?"

"Where are you scratching your cat's hair? The screw is too slow. I'll come." Li Zheng twisted the **** forward. "Tighten it a bit, so the light is stable."

"right……"

"Struggling...struggling..."

"Isn't that...then the laser pointer will blow up if you twist it again?"

"Hey, German goods, you can make it hard... Isn't Jinghua rich? I just tried to test the pressure limit of the laser pointer..."

"Farewell..."

The duo spent the effort of nine cattle and two tigers, and finally shot the laser.

While measuring and drawing a light graph, Li Zheng accidentally touched Lin Yujing's hand. Lin Yujing shook the cup with a trembling chain reaction.

"!!!" Li Zhengao said, "You..."

"I blame you!"

"I blew me?"

"Anyway blame you... hurry and refill the liquid..."

"Hey, I didn't expect that your hands are so stupid, and the cerebellum is probably not good." Li Zheng waited for Lin Yue to look up the new liquid, looking up, a little anxious, "not good...the others have already finished... "

"Why do they..."

"No, I have to fill in the experiment report anyway..." Li Zheng took a deep breath and said, "Let's go the evil way."

"evil ways?"

"People in our group have said that there are four evils in physics experiments." Li Zheng gasped and raised his hands in a gesture of fear--

"Taste method to measure the specific heat capacity of unknown liquids."

"The frequency of waves is measured by touch."

"Screwdriver method to measure the internal structure of black box."

"Peeling method to measure the resistance."

After talking, Li Zhengning turned to the glass of unknown liquid.

"The refractive index is not impossible to measure with the taste method... I probably remember the refractive index of common liquids, as long as I can taste it, I can get the answer directly."

"Forget it... forget it..." Lin Yuejing quickly protected the unknown liquid. "If it is toxic... even if it is not toxic, you can't stand hydrochloric acid..."

"No, for safety reasons, the teacher will not take too dangerous solutions." Li Zheng stared at the unknown liquid with some fanaticism. "Occasionally try the evil work, it may be an experience."

"Forget it...the tongue is non-renewable... And can you really taste the difference between hydrochloric acid and sulfuric acid?" Lin Yujing scared the bottle behind him, "I'm not afraid to say'Well' What?"

"I will taste one drop, one drop..."

After the table, Fu Xuefeng could not bear it.

"cough!!"

The two were startled.

"You two... come out..."

Anyway, he went out first with a sullen face.

"Let you practice evil skills!" Lin Yujing scolded, put down the liquid, and glanced down.

Li Zheng just sighed, looked at the liquid, still didn't hold back, touched a drop, confirmed that he didn't feel it, and licked again.

syrup……

Hmm... fill up the refractive index with 1.3.

After filling it out, he went out.

"Hah!" Qi Yingnan turned his head to gloat, "No, Li Zheng, even for a long time, no coordinate chart was drawn."
