After two years of marriage, the officer husband can’t stand it any longer.

The actual battle is ongoing and will be completed within three days.

!!!

Gu Beinian was also very busy every day. He had to go to class and design drawings and make clothes. He didn't know what Lu Nanchen was doing. There was no news for several days.

In the teacher's office, everyone talked about Teacher's Day and the Mid-Autumn Festival Party.

"Teacher Gu, you guys who are engaged in physics, what kind of performance are you preparing for this year? Isn't it the same as in previous years, a small science experiment?"

Teacher Ji raised his eyebrows with a mean expression.

Gu Beinian leaned on his cheek and said, "The team leader will organize it. Anyway, any little magic will do... What about you?" Beinian asked in return.

She is not very interested in these things. Instead of engaging in such nonsense, it would be better to take a good vacation and rest.

"Martial arts!" Teacher Ji raised his fist, "Let's show everyone our physique! Show off our spirit of experimentation!"

Everyone burst into laughter.

"Come on, with your small body and martial arts skills, you're afraid you can't do Tai Chi?" a teacher joked.

"Of course it's not Tai Chi. I graduated from the Physical Education Institute. I was No. 1 in the shot put competition at the school sports meeting!" Teacher Ji shook his arm. He was really strong. His muscles were tight when swinging. He could imagine throwing the shot put. the power of.

"That's right, we, Teacher Ji, have been practicing since childhood." Another teacher echoed the joke.

Teacher Ji naturally didn't care about the joking among colleagues, and pointed the finger at Teacher Xiao Zhao: "Teacher Xiao Zhao, your Department of Medicine will not rescue patients this year and then crush the patient's head off, right?"

Everyone laughed, and Teacher Xiao Zhao also smiled awkwardly. Last year, they were a nursing student. It was just a small episode, and she didn't hold back. The good performance turned into a comedy show, and the model man's head was directly smashed by the student. The button fell off and Gulu rolled to the principal's feet...

All the students in the auditorium were laughing.

Gu Beinian drank a glass of water and hurriedly picked up the textbook: "Let's go, let's go to class."

Teacher Ji waved perfunctorily: "Go ahead, go ahead."

After Gu Beinian left, everyone began to discuss her personal life again. She got married at such a young age, and her husband was a soldier. They didn't know if she could bear the lonely days.

In the classroom, she wore a bee to teach and designed an interesting scientific experiment for everyone. The principle of this experiment is to use the knowledge of physics and chemistry to see wonderful chemical reactions and experience the magic of technology.

Gu Beinian first introduced the experimental equipment, and then began to explain the experimental principles. Some students even took out their notebooks and carefully recorded the experimental steps.

Then, she invited several classmates to come on stage to help her complete the experiment.

First pour a white powder into a transparent container, add some water, and then use a small stick to stir evenly. As the audience gasped, the liquid in the container began to bubble and turn a beautiful blue.

"This is the key to the experiment." Gu Beinian explained: "This powder is called basic copper carbonate. It will decompose into copper hydroxide and carbon dioxide gas in water. During the stirring process we just stirred, the carbon dioxide gas came out of the liquid. It was released and bubbles formed.”

Then, he took out another test tube and added some dilute sulfuric acid into it. She said: "Now let's do a more interesting experiment and put an iron nail into a test tube."

Gu Beinian slowly poured dilute sulfuric acid into the test tube. He heard a "sizzling" sound, a wisp of white smoke came out of the test tube, and the iron nails were corroded instantly.

The audience was amazed and applauded. Gu Beinian explained: "Dilute sulfuric acid is a strong acid that can corrode metals. In our experiment just now, iron nails reacted with dilute sulfuric acid to produce hydrogen and ferrous sulfate. The hydrogen will burn at high temperatures and generate a lot of heat. , this is the white smoke we see.”

Then, Gu Beinian designed a small game for the audience to come on stage and participate in the experiment. The rule of the game is to control the nails in the test tube to move up and down under her command. Whoever can make the nails move accurately under the command will get a small gift.

After the game started, the students came on stage one after another to try it out. Some people were too nervous and rushed, causing the test tube to break, causing bursts of laughter. Others were very calm, calmly controlling the test tube and making the nails move accurately.

In the end, three students received small gifts. They excitedly waved the prizes in their hands, showing the charm of scientific experiments.

After class, the principal called her personally and asked her to come to the office.

She was a little uneasy along the way. She was so good, why was the principal looking for her?

Dong Dong~ She knocked on the door, and there was a voice asking to come in.

Gu Beinian walked in and saw in addition to the principal, an acquaintance and an unknown leader. She did not say hello because she was not sure whether the other person was here for business.

"Principal, are you looking for me?"

Principal Fang stood up and looked at her with a smile: "Teacher Gu, these two are comrades from the People's Liberation Army of the army. I need to ask you for advice on some issues."

Gu Beinian took a look and saw that the two old comrades saluted her at the same time. She smiled lightly and said, "You don't have to be so polite. I'll break it."

Li Shengli spoke to her kindly: "Your drawings and suggestions have been approved by your superiors. I hope you can come to the army to provide guidance. Principal Fang has also made an agreement to borrow you for two months. Of course, you must respect this." One’s own will.”

The man next to him also echoed: "Comrade, I have read your information. Your family are all martyrs and heroes who have made great contributions to the people, so I will trouble you this time."

Gu Beinian glanced at the armband and said, "Hey, the commander is here in person. This is her great honor."

Before she could speak, the principal on the side pulled Gu Beinian to the cabinet and whispered softly: "Teacher Gu, this is a good opportunity. When you come back, I will give you a glorious mission for the school. This is an honor. Just agree. "

Principal Fang also cut her.

Gu Beinian replied in words that only the two of them could hear: "I'll think about it."

Principal Fang: ...Uh~

What is there to consider? How many people want to go but don’t have this opportunity? My Teacher Gu, don’t be stupid. Don’t refuse this once-in-a-lifetime good thing!

The principal is very worried. Their school cultivates various technical talents. Many students graduate and go to the army to engage in scientific research. Professor Han is the old army chief who came to the school to teach after his retirement. Gu Beinian is Professor Han's pride. Disciple, just count on her.

She coughed lightly, turned around and looked at the two people seriously: "The commander is here in person, so let's talk."

The few people looked at each other, moved to the battlefield, and came to the military vehicle 212 dedicated to the army.
