Mu Yun felt that everything around him had slowed down.

Whether it was the clouds in the sky, the pedestrians passing by, or the cars moving on the road, everything around him moved more and more slowly as he started.

It is as if there is an illusion that time is gradually standing still.

Only he himself is constantly speeding up.

The rate of the heartbeat, the flow of blood, the speed of the feet, the whole body is faster.

And it's getting faster and faster unconsciously.

His speed had long since exceeded the speed at which he used to run with all his might, but he did not feel tired at all.

And until he noticed people stopping, pointing at his back, or even yelling, he didn't know how fast he could run now.

These passers-by interfered with him.

He really wants to keep up the pace, he wants to know where his limits are, and he even wants to know if he will have them now.

He finally understood why Mr. Song asked him to run away in the back mountain where no one was around.

Because there is no interference from passers-by, he can run as much as he wants without distractions.

When he finally reached the back mountain, he chose a remote path.

The more rugged the trail, the more you don't have to worry about being disturbed.

Mu Yun ran on the rugged mountain road, as light as a swallow.

When he was halfway up the mountain, he finally began to feel like he was about to hit a bottleneck in his speed.

Beads of sweat began to appear on his skin, and a tightness began to feel on the muscles of his calves.

So he continued to speed up, jumping through the mountains and forests with all his might.

He felt himself incarnated as Mercury, the god of Greek mythology, who walked like a fly, carrying the message of the gods between the city-states;

It also feels a bit like Hayao Miyazaki's "Witch Home Delivery Service", Kiki, who has just learned to use a broomstick, is as fast as the wind, shuttling between the streets and alleys of the city.

What's even more amazing is that as the whispers of passers-by and the honking of cars disappear, the sounds that come to your ears become very different.

At this moment, the wind around you becomes like fairy music around your ears, sometimes gentle, sometimes agitated, sometimes chic and flying, sometimes gentle as water.

It's like a lot of wind elves, who specially rushed to his side and played music one after another for him.

That's what it is...... The sound of the wind?

It's an amazing feeling.

Mu Yun couldn't help but sigh.

"You can run so fast just after waking up, the young man has good potential!"

Teacher Song's voice suddenly came from my ears.

Mu Yun was in a state of self-forgetfulness, and he was suddenly frightened.

His left foot was tripped by the old tree root at his feet, and he fell directly into a dog and ate.

"Why did you suddenly appear behind people's backs and talk, it would scare people to death!"

Mu Yun propped himself up from the ground and looked at Teacher Song with angry eyes.

At this time, Qu Ruolan also slowly chased after her, just in time to see Mu Yun fall to the ground, pursing her lips and smiling.

Teacher Song squinted at Mu Yun on the ground, and said with a smile, "Ouch, seeing that you reacted so much, did you hear the sound of the wind?"

Mu Yun replied: "I don't know, but when I ran to the back, I had the illusion that the wind was singing in my ears. ”

"It's good, that's pretty much what it feels like. Teacher Song nodded.

What the hell is it, but you should make it clearer.

But before Mu Yun could complain, Teacher Song continued: "When you were running, did you feel that there was any difference in seeing things with your eyes?"

“...... Eyes?" Mu Yun was stunned when he heard this.

"The faster you run, the narrower your eyes become;

"So when you're used to running at full speed and still being able to catch things with your eyes,

"You've got the Falcon Eyes you need to become a marksman.

In other words, running helps you exercise your eyes.

"Well, didn't you expect that?"

Mu Yun nodded: "I really didn't expect this. Teacher, I really feel like you're getting better and better!"

The latter sentence is not a fake lick, originally Mu Yun always thought that "the sound of the wind" was just talking.

But after experiencing a wonderful experience, I have a practical understanding of what Mr. Song said.

Teacher Song said, "But you should train your ears first.

"Blind people have more sensitive senses than the average person, and in the same way, you don't have to rely on your eyes in the first place.

"On the battlefield, there may be a lot of situations where you can't use your eyes.

"Honing all your senses will allow you to deal with unpredictable situations and opponents.

"While you feel it now, I can tell you about the general content of tomorrow's lecture, so that you can have an expectation in your heart. ”

Teacher Song continued: "Have you heard the story of '100 steps through Yang'?"

Mu Yun nodded frantically, with an expression of "awesome" and "coach, I want to learn".

"That's all pediatrics, and what I'm going to teach you is how to use only your ears to do a hundred steps. Teacher Song said.

"Which leaf are you going to shoot, the wind will tell you where it is. ”

What？

Will the wind tell me??

Mu Yun looked confused, and changed to an expression of "Coach, you're talking about snakes".

"Tsk, look at you don't believe it. Let me show you how. ”

As he spoke, Teacher Song took out a towel from his pocket, tied it to his eyes, and handed out a marker pen and handed it to Qu Ruolan.

"Ruolan, you go to the willow forest over there and mark a leaf with a pen. ”

When everything was ready, Teacher Song turned his back to the willow tree.

He shot an arrow with his backhand, which pierced through a willow leaf and nailed it directly to the trunk of the tree.

is impartial, and it is the piece that Qu Ruolan blackened with a pen.

"It's amazing, how did you do it?" Mu Yun was dumbfounded.

"Is there anything difficult to understand about this? There are more animals in nature that use sound to locate them, whales in the sea, bats in the night, they are all masters of listening to sounds. ”

Teacher Song tried to pretend to be casual and explained, but he still couldn't hide his complacent expression.

Mu Yun suddenly realized: "Then after learning this, won't I become a real 'Batman'?"

"I guess that's how it can be understood. ”

Teacher Song wiped his forehead, he would be shown by Mu Yun's brain every time.

"But if you want to shoot at a target farther away, you still have to use your eyes.

"After all, sound travels too slowly compared to light.

"And as I said, to be an archer, you have to calculate a lot of things, first of all, the time of the sound back and forth, the parabola of the arrow, ......"

Mu Yun couldn't help but say: "...... It's complicated. ”

"That's right, now you know, why I teach physics, right?" said Mr. Song.

Qu Ruolan saw Mu Yun's sad look and comforted: "Don't be too discouraged, everything in the world makes perfect with practice." Practice a few more times and you'll have mastered it. ”

"Ruolan is right, if you don't have faith, you should practice more. Teacher Song also hurriedly added.

"In the final analysis, it is still the words of the oil seller: 'Without him, only the hand is familiar'.

"As your skills become more and more sophisticated, so will your strength.

"So how long are you going to sit on the ground?

"I've rested enough, but I can't get up. Mu Yun shook his head and said.

"Why?"

"Because I was hungry and just remembered that I didn't even eat breakfast today. ”

Mu Yun said, and his stomach made a very tacit rumbling sound.
