“Ah... I'm so envious of Nana Wa,” Miyue wiped her wet hair and brought her face close to Lily, who was sitting at the table.
“Oh,” the latter replied without turning her head.
“Aren't you going to ask me what I'm envious of?”
“You'll tell me anyway,” Lily pouted.
“Ugh!” Miyue muttered, but finally couldn't help but say, “Did you see how the soldiers guarding the medical ward and the nearby townspeople treated her?
“I saw it.”
“'Greetings, Lady Nanawa', 'Are you leaving, Angel xiaojie?', 'Miss Pine, this is a wheat cake I made with my own hands'... I want to be treated like that too!” Miyue pressed her face against Lily's cheek and was ruthlessly pushed away.
“That's what she earned with her ability,” Lily said calmly, “Haven't you noticed that since the arrival of the Demonic Moon, she's been in the medical ward almost every day, waiting to treat the wounded? Half of the town's natives have received her help, and the rest are basically family members of those who have been helped.”
“You're exaggerating.”
“I'm not,” Lily sighed, putting down the book in her hand, “Although not everyone goes to the city walls to fight evil beasts, getting injured is a very normal thing for the town's residents – miners get their toes hit by ore, kiln workers get burned, and apprentices in steam engine factories and chemical laboratories are even more so.” She paused, “His Highness once told me that Nana Wa and I are the cornerstones of Border Town's medical care, one internal and one external, which allows everyone to maintain high-intensity operations healthily, even in the absence of a safety system. But in fact, I haven't done anything other than preventing epidemics for new refugees.”
“So you're envious of her too, just like me!” Miyue approached relentlessly.
“I'm not!” she said loudly, “Also, stay away from me, you're hindering my reading.”
“Ugh...” Miyue shrunk her head, “But I'm really envious of her.”
“Then you should learn from Nana Wa, actively help every town resident until they know you, are familiar with you, and naturally everyone will greet you wherever you go,” Lily shrugged.
“But I don't have her kind of ability,” Miyue said dejectedly.
“If you don't have ability, then rely on physical strength,” Lily teased, “Anyway, that's how you got by in the Mutual Aid Society camp.”
“You... despicable!”
Back in bed, Miyue was still brooding. Although she knew the other party was right, it made her feel inferior in the Witch Union. And she didn't want to continue like this. She had finally found a reassuring place, but being idle all day made her feel uneasy.
After almost a sleepless night, the next day, Miyue, with dark circles under her eyes, knocked on Roland's office door.
“What's wrong?” the prince asked in surprise, “Did someone bully you?”
“Lily... no, it's nothing,” she leaned over Roland's desk, “Your Highness, didn't you say I have great potential? Why hasn't my ability changed much even now... Is it really impossible to evolve without understanding *Natural Science Theory Foundation*?”
“So that's what it is,” he couldn't help but laugh, “Actually... I've been considering this issue too.”
“What issue?”
“Didn't Agatha say that more than four hundred years ago, even if the witches of the Union lacked a systematic understanding of the world, they could still achieve high-level awakenings? Besides relying on constant practice as a foundation, the rest was enlightenment – which could be triggered by observing real phenomena, or it could come from an occasional flash of inspiration.” Roland said, “However, the awakening produced by this is obviously not as good as the evolved understanding after systematic learning. Agatha's magic power is proof of this, not only is she the lowest among the evolved witches, but she is even inferior to some ordinary witches, such as Sylvie and Andrea.”
“It doesn't matter, as long as I evolve!” Miyue's eyes lit up, “Have you thought of a way?”
“It's not necessarily going to be successful,” the prince spread his hands, “Just treat it as a try.
What's your opinion on magnetism?”
“Uh... a force exerted by a magnetic field on magnets and electric currents placed in it. The directional movement of electrons produces magnetism.”
“That's the original words in the book,” he laughed, “You memorized it quite well, but I guess you don't understand the content at all.”
After hesitating for a moment, Miyue nodded.
“You've seen iron filings simulate magnetic field lines, you know the direction of magnetism, and you've also seen a DC generator. So I think... you may not be able to make a closed circuit cut magnetic field lines quickly, but you can change the magnetic field you form, and then personally experience the change from magnetism to electricity.”
“I... don't quite understand.”
“The essence of electromagnetism is the change in magnetic flux in a closed circuit. 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, by cutting magnetic field lines,” the prince drew a schematic diagram on the paper, “What if the area is constant? That would be a changing magnetic field... If the magnetic field changes, it is equivalent to a change in magnetic flux.”
“...” Miyue opened her mouth, but found that she couldn't understand a single word.
The prince laughed, “It doesn't matter if you don't understand, you just need to do the following – quickly release and collect your own magnetic force, instead of continuously using your ability.”
“Then what?” Miyue waited for a while, but found that he didn't continue.
“That's it,” he shook his head, “Just this one step.”
“Eh? Just keep releasing magnetic force?”
“That's right, if possible, it would be best to change the direction of the magnetic field lines at the same time... for example, from your left hand to your right hand.” the prince laughed, “You should practice this method first, and I will prepare a 'small toy' for you. When you master this method, you will naturally understand its meaning.”
...
Two days later, Miyue received the so-called small toy from His Highness. It was a square frame made of copper wire, with a transparent spherical glass connected to the top, less than half a fist in size. If you look closely, you can see that the copper wire is broken in the sphere and connected by a much thinner metal wire.
In addition, there was a note: "Hold the ends of the square frame with both hands and practice your ability. Note: Remember to close the curtains and hide the glowing stones."
What kind of game is this!
She scratched her head, but finally obediently did as the instructions said – anyway, it's all practice, just pretend it doesn't exist.
Quickly releasing and collecting her ability was not difficult, but changing the direction of the magnetic force gave Miyue a headache. After all, magnetism was like a part of her that was born with her, and at first it was like asking her to breathe through two nostrils alternately. Although she had said goodbye to poker in the past two days and practiced this skill all day, she could only maintain it for a few seconds.
She took a deep breath and mobilized the magic power in her body.
At first, she didn't feel any different, but soon, Miyue saw a red light.
The metal wire in the glass ball turned into an orange-red thin line, and then the light became stronger and stronger, and in the blink of an eye, it became dazzlingly bright – Miyue could hardly believe her eyes. The dark room was illuminated by a soft light that she had never seen before. This light was much purer than a candle.
Until with a soft "pop" sound, the red light dissipated and everything returned to darkness again, she had not recovered.
