Faced with Fangzheng's question, the girls looked at each other speechlessly.
"Huh? What's wrong? "
"No, how should I put it …."
Erika looked at the skateboard in front of her with a troubled expression.
"This feels very dangerous. Isn't there a better design? I feel like I'll fall if I'm not careful …. "
"You don't have to worry about that. I've prepared for it."
It wasn't that Fangzheng couldn't understand Erika's worries, but it was a pity that strictly speaking, this was indeed the only solution for now.
The reason was simple. The basic principle of general flying magic was to use magic to suck in a large amount of air from the front and then expel it from the back, thus creating an "airflow channel" in the air. Of course, if it was just an application of the principle itself, then magnetic levitation or gravity control were also options. But the problem was that it would consume a lot of magic power to modify it, and it would be impossible for mages who were not skilled enough to use it.
Only flying and changing directions through airflow was the most labor-saving method.
At least it was better than gravity control.
In addition, the center of gravity was also an important part that needed to be controlled. The advantage of the skateboard was that the user only needed to control the center of gravity under his feet and did not need to adjust the direction of his center of gravity again.
Of course, if Fangzheng wanted to, he could also use other techniques to create similar flying devices, but the problem was that those spells either had high requirements on the user, consumed a lot of magic power, or simply required very high-end materials to make.
These were obviously not "general use".
"Then I'll give a demonstration first. You guys just watch from the side."
It was not that Fangzheng did not understand the girls' caution and uneasiness. After all, this was flying magic, unlike other magic. If something happened while flying in the air, they would either die or be crippled from the fall.
"Will it really be okay?"
"No problem. In fact, I tried it before you came."
Fangzheng waved his hand, then stood up and walked out of the room. The four girls looked at each other and hurriedly followed. Soon, they walked out of the warehouse and came to the lawn in front of the gate. Fangzheng had already put the skateboard on the ground, adjusted it, and stepped on it. Then, he turned around and stared at them.
"Alright, let me demonstrate it to you first.... First, we have to step on the skateboard, then inject..."
Following Fangzheng's words, the girls soon saw streaks of light appearing on the skateboard. Seeing this, the Northern Mountain Gui's taciturn face revealed a surprised expression.
"What magic is this?"
"Fixed Magic. This magic will connect me to the skateboard, so I don't have to worry about falling off the skateboard.... And then this...."
"Whew —!!!"
As Fangzheng spoke, the sound of air jets rang out. Then, the skateboard that Fangzheng was standing on swayed a little, then left the ground under the impact of the strong airflow and rose into the air.
"It's the same as piloting a fighter jet. If you put your center of gravity forward, you'll be descending. On the other hand, if you push your center of gravity back, you'll be ascending. You also have to pay attention to the angle. Then, continue to inject the Pangzheng, and the speed will increase.... "
Following Fangzheng's words, the skateboard began to move forward slowly, and the four girls subconsciously followed. At first, they walked beside Fangzheng, then they started to trot. But soon, Fangzheng sped up. Accompanied by the whistling of the violent airflow, he sped forward on the skateboard and flew into the sky.
"Wow —!!!"
Mitsuka clenched her hands in front of her chest, her eyes shining. Erika and Shibata Miyuki also widened their eyes in surprise, looking at Fangzheng flying into the sky.
"He's really flying!"
In any case, flying had always been the hope and desire of mankind. Now that they saw Fangzheng flying into the air, the girls suddenly became excited. Even the usually taciturn Kitayama Ki showed an excited expression at this moment. He stared at Fangzheng, who was soaring in the sky on the skateboard.
As for Fangzheng's actions, it was the same as what he had told the girls previously. He was like a surf as he spun and slid in the sky. After a while, he made a huge circle before suddenly plunging down. Following that, his body moved slightly to the side before sliding forward. In the eyes of the girls, Fangzheng was like a bird circling in the sky. It was mesmerizing.
After a while, Fangzheng lowered his altitude again and landed steadily on the ground. At the same time, the girls ran over eagerly.
"I didn't expect this to really fly!"
"That's amazing! Haruhiko!! "
"See, as I said, this thing is quite simple. As long as you have experience in skateboarding or surfing, you'll be able to learn it easily."
Fangzheng stepped down from the skateboard and smiled at the girls.
"So, who wants to try?"
"Is it really not dangerous?"
At this moment, even Mitsui Suika, who was the most cowardly and introverted, showed an eager expression, not to mention the others.
"I also made a safety device. Once the skateboard senses that it has lost control and is falling down, it will spray a large amount of air from the nozzles on both sides to slow down the speed of the fall, so that the user can regain control or land relatively safely. But if you ask me, I don't recommend beginners to fly too high, lest they fall too badly."
"I want to try!"
Unexpectedly, the first to speak was the Kitayama Ki, who was usually the most taciturn of the four and rarely showed any expression. At this moment, she had a different expression from her usual expressionless face. Her face was flushed with excitement.
"I'm going to change my clothes now!"
After saying this, the Kitayama Ki turned around and went back to the activity room, and the other three girls hurriedly followed.
Unlike Fangzheng, they could not wear their school uniforms and ride the skateboard. The reason was simple: the girls' school uniform of No.1 High School was different from the school uniforms of the worlds Fangzheng often traveled to. It was not designed to be a miniskirt or a short skirt. Instead, the inside of their clothes was a sleeveless cheongsam, and the skirt extended to below their knees. Such a design was quite conservative. Although it did not affect their daily activities, it was a different matter if they wanted to exercise.
This was also the point that Fangzheng was most dissatisfied with. He usually lived by looking at girls' naked bodies under their skirts, but the uniform design was so conservative that he couldn't even look at it ….
And it was troublesome to take it off.
Soon, the girls came back in sportswear. Then Fangzheng began to teach them how to use the skateboard.
The difficulty of flying a skateboard was not high. The main thing was to maintain the balance of the body, stabilize the center of gravity, and overcome the fear of flying.
At first, the girls were a little nervous, but Fangzheng also signaled them to keep the height at two meters so that they could avoid falling. Then, they began to practice with this height as the center, then gradually increased the height and slowly got used to it.
After the initial nervous period, the girls were so addicted to it that they could not extricate themselves. They even skipped the rest of the class and kept flying in the air, as if they could not fly enough.
Unfortunately, human beings had their limits after all.
Erika and Shibata Miyuki were the first to run out of magic power. They had to reluctantly return to the ground — after all, this was a machine powered by magic power. Without magic power, they would fall from the sky and die.
Even so, when the two returned the skateboard to Fangzheng, they were still reluctant to part with it. Shibata Miyuki even showed an expression as if she was about to cry.
Suika Mitsui and Kitayama Ki lasted longer, but unfortunately, they were not perpetual motion machines with infinite magic power. When Fangzheng was sure that the magic power of the two was about to run out, he stopped them with a stern voice. Although they were a little reluctant, the two had to return to the ground.
Overall, this experiment was very successful. In the eyes of the girls, although the Hoverboard did not seem to be reliable, they found it to be very reliable after getting used to it. It was just like a bicycle. At first, they always felt that a two-wheeled bicycle would overturn, but in fact, after getting used to it, they would no longer feel afraid.
As for the endurance, Fangzheng also tested it. Shibata Miyuki and Erika, the two second-year students, could last about four to five hours at the average speed, while Suika Mitsui and Kitayama Ki, who were the top students of the first course, could last about seven to eight hours. Of course, considering that these guys were playing crazily and pointlessly consumed a lot of magic power, maybe the time could be extended again.
For now, the consumption of magic power had been suppressed to a very low level. But for Fangzheng, the more experimental samples, the better.
Well, it was about time to pull Mayumi Shichinao and the others over to try it.
So naturally, Fangzheng turned his attention to his colleagues in the Student Union.
"Kasugano."
Just as Fangzheng was thinking about how to trick … no, invite Mayumi Shichinao and the others over, Kitayama Ki came up to him.
"Hey, Kitayama, it's rare for you to take the initiative to look for me. What's the matter?"
Looking at the Kitayama Ki in front of him, Fangzheng asked curiously. This short-haired girl also had a very cute face, but unlike Suika Mitsui, she gave off a slightly cold and flat feeling. Her tone rarely fluctuated when she spoke, and her expression was also very indifferent. Most of the time, she was more like a bystander, seemingly not very active in most things. The reason why Kitayama Ki joined this place seemed to be purely because Suika wanted to join. Although she had also benefited a lot from Fangzheng's teaching, the relationship between the two could only be said to be relatively good.
Shibata Miyuki and Erika were more likely to take the initiative to chat with him, but Kitayama Ki was very rare.
"Yes."
Kitayama Ki nodded.
"Now that you've realized the universal flying technique, what are you going to do next?"
"You should have already thought of it."
In the face of Kitayama Ki's question, Fangzheng chuckled.
"Just as well. Even if you didn't come to me, I was going to go to you … You should understand what I mean, right?"
"Of course."
The Northmont Xiu nodded once more. This time, her eyes flashed with a spirited light.
"The Kitayama Financial Group hopes to cooperate with you and develop flying skateboards together, Kasugano."
