What did he see: a system that was detached from an external energy supply and was still generating its own electricity!

Thinking that Mystery Moon's abilities are enchanted types, the answer is simply out of reach, and she imparts a whole new trait to the metal frame, using magic to provide a source of energy. Pen, fun, and www.biquge.info

"How did you do that?" Roland exclaimed.

"You said that electricity and magnetism are interrelated and inseparable, and I can't help but wonder if if my ability to make an object magnetic, can it also make it produce lightning? You said that creating lightning requires a change in magnetic force, so I tried to attach the repetitive magnetic force to the copper wire, and it turned out like this......" Mizuki replied cautiously, her eyes full of anticipation.

I see...... The prince thought to himself that the current does produce a magnetic field, but the magnetic field does not produce an unconditional current, which must act on a closed coil, and at the same time there is a change in the magnetic flux - and whether it is to change the magnetic area or change the magnitude of the magnetic force, it requires external energy to achieve this.

Mystery Moon's new ability replaces this part, causing the magnetic force to change on its own without interference from external forces, and if it had been before, Roland would have thought it was a perpetual motion model, but now he understands that the witch's ability cannot be measured by common sense - the magnetic properties of the enchantment do not necessarily come from the magnetic poles, just as black fire is not fire.

It's all magical.

The only thing he was curious about was that Mystery Moon had never noticed the magnetic change of the enchanted object before?

When Roland asked this question, she nodded at first, but quickly shook her head and said, "When I was in the Mutual Aid Society, I also thought about making the magnetism of objects change at will, and when not in use, I could reduce the magnetic force so as not to cause trouble to the other sisters, but it didn't seem to work, the magnetism of objects was always maintained at a fixed size, I thought this idea was impossible to achieve, so I didn't try again." ”

Sure enough, Roland turned his head and asked Nightingale, "Her magical form ......"

"It's condensed," said the nightingale, smiling as she emerged from the mist, "like a surging blue wave." ”

Mi Yue's voice suddenly became excited, "Could it be that I'really—"

"That's right, your abilities have evolved," Roland affirmed, "and without a long period of tireless practice, it would have been impossible to comprehend the key to promotion so quickly, and you have performed very well." From today onwards, you are the sixth witch of the Witch League to evolve. ”

"Congratulations," Nightingale smiled and walked over and patted her on the head.

"Then can I do more for His Highness now?" said Mitsuki's eyes sparkling.

"Well, too many to count," Roland curled the corners of his mouth, "as I said before, your potential is limitless. But...... Rest for a while, your dark circles are almost as big as your fists. Wait until the afternoon, and then let me put your skills to the test. ”

"Hmm!" she nodded vigorously.

As soon as Mysa Moon left the office, Nightingale closed the door and came over. Instead of returning to the table or the floor-to-ceiling window, as she usually did, she approached Roland in a flash, pressed his shoulders excitedly, and bent over - the pale blonde hair fell down his cheeks, making him feel a slight itch. Looking at the other party's watery eyes and soft red lips, Roland's heartbeat suddenly increased several times.

Eh, what's going on! Does she want to be here and ...... herself? But it's still daylight.

"Tell me how. Nightingale's words made the prince stunned, wait...... The story doesn't seem to be the same as you thought?

"How?"

"You don't need to understand the Theoretical Foundations of Natural Science to evolve," she said excitedly, "With the results of the Mystery Moon's exam, it's impossible to understand the content of this book, but you still let her evolve new abilities!

Uh, is it for the sake of evolution, this request is really regrettable - no, it makes people breathe a sigh of relief, Roland cleared his throat and gathered his thoughts, "I'm afraid it's difficult for your ability to break through by the method of epiphany." ”

"Why?"

"According to Agatha, this requires witnessing phenomena related to abilities in reality to cause evolution, and your fog is so incredible that I don't know exactly how it works, let alone guide you to it," Roland explained, "If you want to condense your magic, I'm afraid that in the end, there is only one way to go, and that is to master all the knowledge of nature and physics, and advanced mathematics is also a skill that must be mastered." ”

Nightingale's expression immediately fell, and she walked feebly to the chaise longue and leaned limply against the back of the chair, as if she had been hollowed out.

After lunch, Roland spent half a day putting Mystery Moon's new abilities to a full test.

He named this ability the Indefinite Magnetism, which, like the previous Magnetism, can be attached to any object and periodically changes following the mana injected during the enchantment, but has little to no electric current effect on insulators.

In addition, her magic power is also the lowest among the Evolution Witches, and she can only light up the two magic stones on the Divine Will Rune, which is half less than Maisie. The enchantment ability has very high requirements for mana, and the greater the upper limit of the change in magnetic force, the longer the duration, and the more amazing the mana required. After a series of tests, he found that the new ability of the Mystery Moon was relatively stable as a battery, and it was not enough to drive a large motor and reach the power of the current steam engine - the DC motor assembled during the initial water electrolysis was converted into an electric motor, and the results were quite bad. The Mystery Moon's motor rotor consumes all of its mana enchantment, and can only last half a day's running time, which almost negates its practical value as a source of power.

However, Roland doesn't reveal this to Mystic Moon, but encourages her to continue practicing her new abilities and not to fall behind in her studies - evolution is not easy for her, and any bad news could bring her down.

Fortunately, the evolution of ability is not a one-shot deal, as long as the mystery moon can make another breakthrough through systematic learning, there is still a chance to make up for the lack of magic power.

Roland also thought of what Agatha had said about how multiple people could work together to create the Glowing Stone—if there was a witch who could manipulate or transfer magical power, it would be possible to bypass the limitation of Mystery Moon's own lack of strength.

In the evening, he found Tilly Wimbleton.

"Magic-controlled type of assistant witches?" she pondered for a moment after listening to the prince's narration, "There is no one on the Isle of Sleep who has such abilities. ”

"Yes...... Is that so?" Roland couldn't help but sigh, it seemed that Mystery Moon could only rely on her own efforts to improve.

But Tilly's next sentence made his expression change, "But I know where you can find a witch like this." ”
