The lectures are loud in the classroom.

The students listened quietly, raised their hands to ask questions from time to time, and the classroom atmosphere was lively and good.

"..."

Wang Qicheng, who was passing by the classroom on the fourth floor, stopped, and saw the people standing on the podium lecturing through the transparent window.

The calm heart lake was violently turbulent, and the prejudices of the past were completely shattered.

He had to admit how ridiculous those thoughts were.

It's not that she doesn't know about airplanes, on the contrary, she has a very thorough understanding of various knowledge about airplanes and has a wealth of knowledge.

She has a wonderful charm in her class that can't help but cheer up.

Wang Qicheng laughed dumbly, "No wonder."

No wonder Xiao Shuyi spoke highly of her, and has always firmly believed that it was the discerning eye.

"..."

During the lecture, Yan Zhixu noticed the gaze from outside, and out of the corner of his eyes, he casually swept over to see Wang Qicheng standing outside.

She nodded slightly, then continued to explain the propeller of the plane to the students.

"The propeller of the plane is driven by the engine and rotates at a very fast speed, which creates a pulling force that pulls the plane forward."

"Some people think that when the propeller rotates, the blades **** air into the back row, and use the reaction of the airflow to pull the plane. In fact, this statement is wrong, we can look at its blade design..."

The students in Class 4 did not notice Wang Qicheng standing outside, and after watching for a while, he quietly left.

Time is like an hourglass on your fingertips, slipping away without anyone noticing.

A forty-minute class ends.

Yan Zhixu turned off the big screen and pulled out the USB flash drive. The students in the audience swarmed up and enthusiastically gathered around the desk to ask about all kinds of knowledge.

She answered questions patiently.

After returning, he thought of something, and tapped his fingers on the table, "By the way, there will be an exam with four classes in a month, and the exam will be all kinds of knowledge about airplanes. I hope you can listen to the class and take notes within this month. Shame on me to double up on physical training."

Everyone's enthusiasm was not affected at all, but Zhou Xiaoxiao patted Huo Rin's shoulder with a smile.

"Teacher, don't worry, with Huo Shen, the first grade must belong to our class."

Seeing this girl's smiling face, Yan Zhixu raised her eyebrows and poured a basin of cold water.

"Huo Rin's ability to take the first place is because of his own talent and intelligence. If you fail the exam, it means that my teaching ability is not good."

An extremely cruel sentence fell, and Zhou Xiaoxiao was stabbed with blood flowing all over her body.

The cheerful little face dimmed, and he looked at Huo Rin with a faint look and then looked down at himself.

The same people, but how can the gap be so big? Huo Shen's head is filled with brain water. Could it be that his own is filled with bean dregs?

Huo Rin noticed Zhou Xiaoxiao's gaze, calmly closed the note, and closed the lid of the ballpoint pen.

"Your brain may not be developed enough, remember to read more books, lest the brain that is not much rust."

His voice fell.

Not only did Zhou Xiaoxiao cast a resentful look at him, but the other students also looked badly.

Guys: "..."

Huo Shen, are you not afraid of being beaten by a group of scumbags when you say such things?

Yan Zhixu tucked the USB flash drive into his trouser pocket, "Take a break between classes and then continue with other classes. In the afternoon, there will be physical fitness anti-dizziness training."

This time the other students quickly looked away and started worrying about themselves.

It's okay not to say these words, but as soon as I say it, I feel like the world is spinning.
