Chapter 404 The Road to Magnetoelectricity

"Ah... I'm so envious of Nana," Miyue wiped her wet hair, and put her face in front of Lily who was sitting at the desk.

"Oh." The latter replied without looking back.

"Don't you ask me what I envy her for?"

"Anyway, you'll talk about it soon," Lily curled her lips.

"Damn it!" Mystery Moon muttered, but she couldn't help but said in the end, "Didn't you see how the soldiers guarding the hospital and the townspeople nearby treated her?

"I see."

"Master Nana, hello, Miss Angel, are you leaving? Miss Pine, these are wheat cakes made by me... I really want to be treated like this!" Mystery Moon pressed her face to Lily's cheek , and was then ruthlessly pushed away.

"That's what she got in exchange for her ability," Lily said calmly, "Didn't you notice that after the arrival of the Demon Moon, she stayed in the hospital almost every day, waiting to treat the wounded at any time? Among the aborigines in the town , Half of them have received her help, and the rest are basically the family members of the recipients."

"You're exaggerating."

"Not at all," Lily sighed, and put down the book in her hand, "Although not everyone will go up the city wall to fight against evil beasts, it is quite normal for town residents to be injured. Kiln workers will be scalded, especially apprentices in steam engine factories and chemical laboratories." She paused, "His Highness once told me that Nana and I are the cornerstone of Border Town's medical treatment. In addition, it allows everyone to maintain high-intensity operations in a healthy manner when the security system is still blank. But in fact, I have done nothing else except for epidemic prevention for new refugees."

"So you are also envious of her, just like me!" Mysterious Moon leaned over and said unyieldingly.

"I didn't!" she said loudly, "Also, stay away from me, you are hindering my reading."

"Woo..." Miyue shrank her head, "But I really envy her."

"Then learn from Nana, and take the initiative to help every townsman until they know you and are familiar with you. Naturally, people will greet you wherever they go." Lily shrugged.

"But I don't have her ability," Mystery Moon said in frustration.

"If you don't have the ability, you can rely on physical strength," Lily laughed. "Anyway, you came here in the mutual aid camp."

"You... despicable!"

When she went back to bed, Mystery Moon was still brooding. Even though she knew what the other party said was true, she felt that she was going to be inferior in the Witch Union. And she didn't want to continue like this, and finally found a place of peace that she imagined, and doing nothing all day always made her feel uneasy.

After almost a sleepless night, the next day, Miyue knocked on the door of Roland's office with dark circles under her eyes.

"What's wrong?" the prince asked in surprise, "Have you been bullied?"

"By Lily... No, it's nothing," she leaned over to Roland's table, "Your Highness, didn't you say that I have great potential? Why hasn't my ability changed so far... Can't you understand "Natural Science Is it really impossible to evolve without theoretical basis?".

"So that's what happened," the other party couldn't help laughing, "Actually... I've been thinking about this issue too."

"what is the problem?"

"Didn't Agatha say that more than 400 years ago, even though the witches of the Federation lacked a systematic understanding of the world, they could still achieve high-level awakening. Apart from relying on continuous practice as the basis, the rest is epiphany. It can be caused by the observation of real phenomena, or it may come from an accidental inspiration." Roland said, "However, the awakening caused by this is obviously not as good as the understanding and evolution after systematic learning. Agatha's magic power is proof, not just evolution The lowest among all the witches, even inferior to some ordinary witches, such as Sylvie and Andrea."

"It doesn't matter, as long as it evolves!" Mystery Moon said with bright eyes, "Have you figured out a way?"

"It may not be successful," His Royal Highness spread his hands, "Just take it as a try. What's your opinion on magnetism?"

"Uh... a magnetic field that acts on a magnet and an electric current put in it, and the directed motion of the electrons creates the magnetic force."

"This is the original words in the book," he said with a smile, "you memorize them quite well, so you probably don't understand the content at all."

After a moment of tweaking, Mystery Moon nodded.

"You have seen the magnetic field lines simulated with iron powder, you know the direction of the magnetic force, and you have seen DC generators. So I think...you may not be able to make the closed circuit cut the magnetic field lines quickly, but you can change the magnetic field formed by yourself, and then personally Experience the change from magnetic to electric."

"I... don't quite understand."

"The essence of magnetoelectricity is that the magnetic flux in a closed circuit changes. If you want to change the magnetic flux in a constant magnetic field, you can only achieve it by changing the area, in other words, cutting the magnetic induction line," Wang Zi drew on paper Schematic diagram, "What if the area is constant? That is a changing magnetic field... If the magnetic field changes, it is equivalent to changing the magnetic flux."

"..." Miyue opened her mouth, but found that she couldn't understand a single word.

His Royal Highness laughed out loud, "It doesn't matter if you don't understand, you just need to follow the following method to quickly release and contain your own magnetic force, instead of continuously exerting your ability."

"And then?" Mysterious Moon waited for a while, but found that the other party didn't continue talking.

"No more," he shook his head, "it's just one step."

"Eh? As long as you keep releasing the magnetic force?"

"That's right, if it's possible, it's best to change the direction of the magnetic force line...for example, from the left hand to the right hand." The prince smiled, "You can practice this method first, and I will prepare a small toy for you, waiting for you Once you master this method, you will naturally understand its significance.”

...

Two days later, Mystery Moon got what His Highness called a small toy, which was a square frame made of copper wire, with a transparent spherical glass attached to the top, less than half the size of a fist. If you look closely, you can see that the copper wire breaks in the sphere and is connected by a much smaller wire.

In addition, there is an instruction manual: hold the two ends of the box with both hands and practice the ability. Note: Remember to close the curtains and hide the luminous stone.

What kind of game is this!

She scratched her head, and finally obediently followed the instructions in the instructions. Anyway, it's just practice, so just pretend it doesn't exist.

It is not difficult to quickly display and converge the ability, but changing the direction of the magnetic force caused Miyue a big headache. After all, the magnetic force was like an innate part to her. At first, it was like asking her to inhale through two nostrils in turn. Although he bid farewell to poker these two days and practiced this skill all day long, he could only maintain it for a short period of time.

She took a deep breath, mobilizing the magic in her body.

At first, she didn't feel any difference, but soon, Mysterious Moon saw a red light.

The metal wire in the glass ball turned into a thin orange-red line, and then the light became stronger and stronger, and in a blink of an eye, it was too dazzling to look at Miyue, and I couldn't believe my eyes, the dark room was surrounded by a kind of Illuminated by a soft light that has never been seen before, this light is far purer than a candle.

Until with a soft sound of "Bo", the red light dissipated, and everything returned to darkness again, and she failed to recover.
