In a room in the center of a city.
A middle-aged man was sitting in a chair, leaning forward slightly, staring at the computer screen, his left hand pounding the keyboard crazily, and his right mouse kept sliding.
Crackle crackle crackle crackle——
The sound of keyboard tapping is particularly harsh in this quiet room.
At the side, a 15-year-old boy looked at this scene, and half a day later, he sighed a long way.
"Shifu!" Bai Hao called.
"What?"
Shen Feng... that is, the man called Shifu by Bai Hao. He didn't look back, but simply responded to him.
At the moment, he is sweating and impatient, and has no time to respond to Bai Hao, because the game has reached the critical moment, so he must go all out.
Seeing this scene, Bai Hao didn't have much to say. He had to wait until Shifu finished the game.
"Be careful, someone!"
When Shen Feng is preparing to enter the river, Bai Hao immediately reminds him.
"What?"
Shen Feng is preparing to respond, but it is too late. Three big men jumped out of the grass and killed the game character controlled by Shen Feng.
"Damn it!" Shen Feng couldn't help shouting.
"Calm down, Master."
"It's boring. What kind of ghost game. It's a hell of a bitch. I dare not fight openly and honestly. Bah!"
As he said this, Shen Feng directly pressed "Exit" to exit the game, and without hesitation clicked "Confirm".
"Master, this is my number, and this one is ranked."
Bai Hao wiped his sweat and said.
"Why? Do you have any opinion?" Shen Feng raised his eyebrows.
"No, no opinions." Bai Hao hurriedly waved his hand.
"That's about the same. It's said that you young people should not indulge in games all day long at home. What's the meaning of such boring things? Go out to catch demons, fight monsters, and improve your accomplishments when you have time. This is what you should do."
"Yes." Bai Hao nodded several times, then took out a book to turn to a page and handed it to Shen Feng.
"Master, after playing the game, let's start today's class! There are several things I don't understand."
"Oh? I don't understand. Show me."
"Here."
Bai Hao pointed to the place above, and then said:
"It's about the aspirant's flight guide. I don't understand one thing."
"Isn't it clearly written on it? Obey the air traffic flight rules, make necessary invisibility, and don't be found by ordinary people. If you expose yourself, inform the people of the Practitioner Administration Bureau at the first time."
"That's not true. It's true. As for flying, I want to know, if I really learn how to fly, should I fly vertically or horizontally in the air? It's not written in this book, so I ask."
"Oh... this is simple. Get me a pen and paper."
"Wait a minute."
Bai Hao immediately turns over a pen and paper and hands them to Shen Feng.
Shen Feng drew a plan on the paper and marked it with clear data.
"You asked this question to a very high standard. In fact, this question was raised long ago, so I will explain it to you by the way."
"Good!" Bai Hao came to his senses and listened attentively.
"That's right. In fact, there is a lot of emphasis on flying vertically or horizontally. In fact, if you are good at mathematics, you can figure it out by yourself. Whether you fly vertically or horizontally depends on your practice."
"How to say this?" Bai Hao did not understand.
"Well, you should have seen some TV plays about immortals on TV. Have you seen some flying ways of immortals and monsters?"
"Yes, I have." Bai Hao thought for a while and suddenly his eyes lit up.
"I see. If you are high in cultivation, you can fly vertically like an immortal. If you are low in cultivation, you can only fly horizontally like a monster?"
"What are you thinking about all day?" Shen Feng glanced at Bai Hao.
"I've talked about mathematics. Why do you still want such a mysterious thing? You need to calculate it in a scientific way."
"Huh?" Bai Hao was dumbfounded.
"How to calculate with science?"
"Look." Shen Feng points to the top of the picture with his pen.
"In fact, what you just said about cultivation is still a bit correct, but it is not the case. Whether you fly vertically or horizontally, you should pay attention to science."
"You should have noticed that when goblins fly horizontally, they usually extend their hands forward."
Bai Hao recalls and nods.
Yes
"Well, this is actually called pitot tube, also called pitot tube. In short, we usually test the total pressure and static pressure of air flow to determine the air flow speed."
Bai Hao is a little confused.
Shen Feng saw his confusion and drew another plan to mark the rising height, as well as the thermosphere, mesosphere, stratosphere and troposphere.
Seeing these professional terms and data, Bai Hao was even more confused.
Shen Feng pointed his pen to the troposphere.
"It's very simple. Flying sideways, just like a plane you usually ride on, if you fly at this height, there will be great airflow fluctuations and high temperatures, which will cause great trouble and serious discomfort to the flying sideways. If you suffer from airflow during the ascending and descending phase, you will suffer from a very serious fall accident if you are not properly protected. ”
"How about flying vertically? It depends on your practice. To be honest, flying vertically is more consistent with the aerodynamic configuration of the air troposphere, which is more conducive to reducing air resistance and saving spiritual power in the body."
"But flying vertically is not good for going to long-term places, and flying too high can easily cause hypoxia, which has many potential safety hazards."
"So the right way is to travel by plane or high-speed railway, which is the safest way."
Bai Hao: "..."
Bai Hao was stunned for a long time before he responded.
"But aren't we practitioners? How can we show our strength if we don't fly by ourselves?"
"What's in his head?" Shen Feng knocked on Bai Hao's head directly.
"Now it is a modern society, so we should learn to live in a modern way. Besides, flying has long been out of date, and it is not easy to learn. Nobody can fly anymore. Give up the idea in your head!"
"All right!" Bai Hao sighed in disappointment.
"Let's learn something else..."
"Lose everything, lose everything..."
At this time, Shen Feng's mobile phone rang suddenly.
"Wait a minute, I'll answer the phone."
Shen Feng takes out his mobile phone, presses the answer key, and puts it to his ear to answer.
"Hmm... It's me... What? Three missing and one missing? Still in a hurry? Are you sure... OK... OK... I understand... Hmm... Come right now!"
With that, Shen Feng hangs up the phone.
Looking at Bai Hao, Shen Feng said earnestly, "I'm afraid I can't teach you today, apprentice. Lao Wang has a strong monster to deal with. I need to go and help deal with it."
"Well, Shifu, go ahead! I'll see you off."
Bai Hao goes to the gate to open the door, but Shen Feng stops him.
"Don't be so troublesome. It's said that it's an emergency, so there are ways to deal with it urgently."
Shen Feng goes directly to the balcony and opens the window.
"Wait! Shifu, what do you want to do?" Bai Hao was surprised and asked hurriedly.
"It's OK. Don't worry." Shen Feng climbed onto the balcony and thought of something. He turned to Bai Hao and said:
"Also, you should not think about flying all day long. It is the absolute principle to concentrate on cultivation. Practice well and be a practitioner who contributes to society."
"Shifu... Shifu... Be careful..."
"Believe in science!"
With that, Shen Feng stepped on the railing and jumped down.
"This is the top floor!!!"
