Academy of Stellar Magic.

After dealing with the daily chores of the college, Principal He Hai came to the lake for a walk.

This is a good habit he has developed over the years, and watching the beautiful scenery of the sunset over the long river helps to keep his mood happy.

Today, however, it seems to be a little different.

Just as He Hai stood aside, quietly enjoying a moment of peace, a strange figure approached quickly from a distance, mixed with laughter:

"Hahaha, you can't compare to mine! Admit defeat and bring ten packs of spicy strips!"

"We're not there yet...... I'm not going to lose yet!"

He Haixun looked at the prestige, and saw two male students riding on a strange car, their legs staring hard, and they all looked like they had turned into circular afterimages.

What surprised He Hai the most was that the car was obviously only two wheels, but it could always be stable and extremely fast?

"Stop!"

He Hai shouted, his voice full of majesty.

The two boys were startled, the movements on their feet couldn't help but slow down, looked around, and finally found He Hai standing by the lake, and immediately jumped off the bicycle in fright, and came to He Hai in panic.

"What are you doing?" He Hai asked.

One of the boys, who was relatively tall, bowed his head and replied weakly, "Your Excellency...... We...... We're having a bike race......"

"Bikes?"

He Hai caught a strange word.

"It's the bike we just ridden......"

The boy pointed to the bicycle they had thrown on the road.

Since He Hai had been exchanging information with secret agents in the Red Fire Kingdom some time ago, and had just returned to the academy for a few days, he had never heard of any bicycles at all, and today was the first time he had seen them.

He Haidao: "Help them over and show me." ”

The two boys immediately ran over and walked to He Hai with their bicycles in a state of anxiety.

He Hai didn't speak, and without saying a word, he carefully looked at this extremely strange-shaped car, there was a pole-like thing in front of it, and the body was very thin, as if it was spliced together by several brightly colored woods.

What made He Hai feel the most strange was that there were two large and small circles under the car, which were covered with dense fangs, and there was a long thing attached to them, which looked a little scary.

"You just rode it?" He Hai asked.

The two boys looked at each other, wondering why the principal asked knowingly, didn't he see it just now?

But they honestly replied, "Yes, Lord Chancellor." ”

looked at the two of them cautiously, for fear of being punished

, He Hai rolled his eyes, and suddenly thought of a good idea.

He stroked his white beard and said in as calm a voice as he could, "If any of you can tell me why it has only two wheels, but it still keeps it steady, and is so fast, he will not be punished!"

As soon as the words fell, the eyes of the two students immediately lit up.

The tall boy said, "Principal, that's right! I didn't believe that this bike could be balanced, but when I got on it, I gradually understood something!"

"Principal, so do I!"

Another shorter boy saw that he was being preempted, and he was not far behind, and expressed his meaning in concise words.

Seeing the two of them scrambling, He Hai smiled and said, "Don't worry. If one person says it once, neither of them will be punished for saying good things. ”

Hearing this, the two settled down a little.

"Let's talk about it first. ”

He Hai pointed to the boy who was relatively tall.

"Yes, Headmaster!" the student leaned over slightly, and continued, "As I understand it, this bike relies on speed to maintain balance! The faster it goes, the less likely it is to fall, and if it is very slow, it is easy to sway from side to side, and it is difficult to control." ”

"Oh?" He Hai raised his eyebrows.

It was the first time he had heard of such a strange thing.

Generally speaking, the faster the speed, the more difficult it is to control.

The short student couldn't wait, and took the initiative to speak: "Principal, what he said is right, I feel the same!"

After speaking, he saw the two of them looking at him with inexplicable eyes, like looking at fools!

"What's wrong?" the student wondered.

The corners of He Hai's mouth twitched: "It's okay." ”

If it weren't for his identity as the principal, he couldn't help but want to complain: What you said is the same as if you didn't say it, why are you in such a hurry to grab the word?

You continue. He Hai motioned to the tall student.

"During the ride, my left and right feet are working at the same time, and the bike is able to move forward by pushing the pedals with my feet!" So I guess that the balance of the bike is also related to the force of both sides at the same time, because in this way, the two forces cancel out the ......," said the tall student.

He Hai touched his beard and nodded constantly, he could see clearly the scene of the two riding just now, it was indeed like this!

"Tell me about what each part of the bike does. He Hai ordered.

"Principal, please look! This is the handlebar, where we hold both hands when we ride, and where we control the direction, and this is the saddle, where we sit, but honestly, I feel like it has

Some diaphragm butt, not very comfortable to sit on......"

Although the student has not been in contact with bicycles for a long time, Zhou Xuanwen has already told him all aspects of the bicycle when he gave Zhao An, and Zhao An told his roommate Wang Kun, Wang Kun is a big mouth, and all the students who bought bicycles came to ask him, and he answered all the questions......

So after going back and forth, soon everyone knew more about some details about the bike, and the speed of getting started was also very fast.

Half a quarter of an hour later.

He Hai already has a relatively comprehensive understanding of the bicycle, he stroked the body, and sighed: "This is really a wonderful idea! The person who can make it must have a talent in the world!"

The dwarf student didn't have a chance to interject when they spoke, he scratched his ears and cheeks anxiously, for fear that the headmaster would punish him in the end, and seeing that the conversation was almost over, he decided to let it go, and said, "Headmaster, I want to say it too." ”

"Oh, tell me about it. ”

He Hai thought that he wanted to add some missing details, and said casually without care.

"Headmaster, this bicycle ......"

The short student was excited, this was an opportunity he had finally gotten, and he was about to talk endlessly about his darkness, but as soon as he opened his mouth, he found that what he wanted to say was finished by the tall boy......

"This bike...... I understand this bike as well!"

After a long time, the dwarf student finally said this.

"Horn!"

He Hai tore off a strand of his beard.

He glanced at the student viciously, and his heart was full of remorse: he should have thought of it a long time ago!

This student couldn't hold back anything else, so why did he let him speak?

Isn't that self-inflicted?

"Hahahaha......"

The tall boy couldn't help it anymore and laughed.

Annoyed and angry, He Hai subconsciously laughed at himself, and waved his hand angrily: "The two of you, chasing and fighting in the academy wantonly, not concentrating on cultivation and study, violating the rules of the academy in your eyes, punish you for cleaning all the toilets in the men's dormitory!"

After saying that, he left with big strides.

The tall boy suddenly shouted, "Principal, my ......"

"What's yours?" He Hai asked, his eyes extremely unkind.

"I didn't ...... Nothing ......."

The tall boy didn't dare to continue, and could only silently watch the headmaster push his precious bicycle away......

He's just bought it for half a day!

Pity him for those 150 packets of spicy strips!
