After Lin Fei and Cheng Shuang had lunch, they found an empty classroom and started self-study.

The building complex on this side of the Nishikyo University of Science and Technology has four rows of academic buildings, and each row of teaching buildings is divided into three ABC buildings.

Even if the summer vacation is long, there are students at Nishikyo University of Technology who have not returned home for one reason or another.

They carried the materials of the physics competition and walked on the first floor of the 4th class.

The classrooms are not completely empty, and there are a few people in each classroom, who are either working hard with pens, or typing on the computer, making PPTs or writing papers.

Lin Fei picked a classroom at random, walked in lightly, and sat by the window.

Cheng Shuang sat next to her.

Lin Fei was silent, and after sitting down, he began to review intently, holding a pen in his hand, writing slowly and orderly.

The trolley travels fast or slow on the inclined plane, generating static or dynamic friction;

The characteristic matrix of the dielectric film, the frequency spectrum width of the F-P cavity modulation;

The Leemand constant calculates the difference in electron energy due to the electron transition, the wavelength difference of the Compton scattering;

Electric dipole, angular momentum theorem, electromagnetic analogy......

Lin Fei digested obscure knowledge points one after another, and they all made beautiful arcs in Lin Fei's mind.

A rational, orderly, beautiful.

There is light in summer, mixed with the buzzing of mosquitoes flapping their wings and the screams of cryptoptera, which seems warm and smart, quiet and active.

Lin Fei felt like a happy child, running on the boundless wilderness, not afraid of falling or getting lost in the haystack.

Studying and earnestness are contagious, and a good study partner can give people an uplifting force.

Cheng Shuang sat next to Lin Fei, even if the two didn't say a word, just looking at Lin Fei's serious appearance, she couldn't help but start the question without distraction.

For a long time, it was crumpled by the black handwriting on the paper and slipped between the fingers.

I don't know how long it took for Lin Fei to raise his head, his hands interlaced, and his wrists that were a little sore and swollen.

For nearly an afternoon, she was doing complex deductions and calculations.

Symbols and formulas, pictures and words, all kinds of intertwined physical knowledge, are her world.

The completion of this handout was smoother than she imagined, but also more difficult than she imagined.

Smoothly, she completely regained her previous knowledge and the state of doing the exam, and her thinking was relatively clear, and there was no big bump in doing it.

The difficult thing is that the physics competition questions, in this world, have a sense of upgrading with the times.

In a word, the topic has become difficult.

And the amount of calculations has increased greatly, and she does not dare to relax at all, and every time she does a question, she has to open a new page of the draft book and write down the process in dense small print from the top left.

She writes slowly and steadily.

If you make a mistake and come back to find the problem, it is more troublesome than fixing bugs on the computer!

Cheng Shuang was also driven by Lin Fei, immersed in the topic, and even forgot the time, and fought an afternoon battle in one go.

This is a phenomenon that she has never experienced in every subject.

She moved her neck and proposed to Lin Fei, "Eat? ”

"Okay."

The two immediately packed up their things and walked out of the fourth teaching building.

I don't know if I was too serious about the question just now and ignored the temperature, Lin Fei suddenly felt a little cold around him, and looked at the air conditioner in front of the classroom: 24 degrees.

Out of the school building, the sweltering summer air really hit me.

Lin Fei stood in front of the steps and was stunned for a moment, his mind empty. I only felt that the cold air conditioning in the examination room just now probably restored the scene of the glacial age, and her fingertips were stiff and her thinking was a little stiff.

This is probably a sign of overuse of her brain, she feels like she has used her brain like an overused machine, and it needs to be oiled and repaired, or it will rot.

And Huang Zhengwen and Peng En's minds are probably like machines that are maintained but not used at the moment, brand new.

Originally, Huang Zhengwen wanted to study hard, but Peng En insisted on pulling him to play in the video game city.

Today is Huang Zhengwen's loss day, and he laughed at Peng En twice.

Penn rightly demanded, "This is your compensation for me." ”

"Just play for a day, it's fine."

Penn used his phone to locate the nearest video game mall nearby.

It's about a kilometer or two, not too far.

The two didn't want to waste money on a taxi, and planned to sweep a shared taxi ride.

However, both of them went around Xijing Institute of Technology and barely found a shared electric frequency car.

Peng En immediately said to Huang Zhengwen: "You ride, I'll sit behind you." ”

Huang Zhengwen looked at the small electric frequency car, afraid that it would not be able to bear the weight of two people, and refused: "This seat is too small, and we can't sit down." ”

"It's fine." Penn had already started sweeping the car, "I'll step on the pole on the rear wheel, and stand on your shoulder." ”

Yes, that's how they went to the arcade.

Peng En stepped on the rear wheel crossbar and stood, leaning on Huang Zhengwen, holding his shoulder with one hand, holding his mobile phone in the other hand and starting to take pictures and videos, shouting "Wuhu" in his mouth.

Peng En took his mobile phone, opened the QQ space, and sent a message.

[I went all the way north, leaving the season with you.]

It's so spicy~】

There are also a few pictures below, one of which is the upward view of Huang Zhengwen.

Huang Zhengwen's face in the picture was a little solemn, he drove the battery car very slowly, and he held the front of the car hard and controlled the direction.

If Peng En could settle down a little bit in the back, Huang Zhengwen wouldn't have to work so hard.

【Dengden~】

Huang Zhengwen's mobile phone rang at this time.

It is the news tone that QQ pays special attention to.

Peng En put away his phone contentedly, put his hands on Huang Zhengwen's back, close to his ears, and said to him, "Who? Particularly concerned? I'll send you a message at this time. ”

Huang Zhengwen was silent, trying to control the balance of the car.

Penn's action of bowing down and speaking gave the battery car a little shake and unbalance.

Huang Zhengwen said: "You stand up, the car is shaking so badly, I can't control it." ”

"Oh." Peng En maintained this action of lying on Huang Zhengwen's body, and basically merged with him.

The car drove for a while, and Peng En seemed to suddenly think of something, and continued to say to Huang Zhengwen: "Your one is particularly concerned, it can't be me, right?" ”

Peng's voice tickled Huang Zhengwen's ears, and the hot breath greatly interfered with his driving.

"Yes." Huang Zhengwen generously admitted.

Huang Zhengwen replied too decisively, and Peng En couldn't say anything about gags anymore.

After Huang Zhengwen took control of the battery car, he added lightly: "You have so many things to do every day, and now we are out again, what if you are kidnapped and I don't receive the news, what if you die?" ”
