What did he see? A system that was independent of external energy supply but still generated electricity on its own!
Considering that Mystery Moon's ability was an enchantment type, the answer was obvious. She had given a brand-new feature to the metal frame, which was to use magic power as a source of energy. Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation
"How did you do it?" Roland asked in amazement.
You said that creating thunder and lightning requires a change in magnetic force, so I tried to attach the changing magnetic force to the copper wire, and the result is like this... "Mystery Moon answered carefully, her eyes full of expectation. "So that's how it is..." The prince thought. "Electricity and magnetism are interrelated, but they are inseparable. I can't help but think, since my ability can make objects magnetic, can I also make them generate thunder and lightning?
"So that's how it is..." The prince thought. "Electric current can indeed generate a magnetic field, but a magnetic field can't generate electric current unconditionally. The latter must act on a closed coil, and at the same time, there must be a change in the magnetic flux. Whether it is changing the magnetic area or the magnetic force, external energy is needed to achieve it."
Mystery Moon's new ability replaced this part, making the magnetic force change automatically without external interference. In the past, Roland would definitely think that this was a perpetual motion model, but now he understood that the witches' ability could not be measured by common sense, and the magnetic force of enchantment did not necessarily come from the magnetic poles, just like Blackfire was not fire.
These were all the effects of magic power.
The only thing he was curious about was, "Has Mystery Moon ever noticed the magnetic force change of enchanted objects before?"
When Roland asked this question, she nodded at first, but soon shook her head and said, "When I was in the Witch Cooperation Association, I also thought of changing the magnetic force of objects at will. When not in use, I can reduce the magnetic force to avoid causing trouble to other sisters. But it seems to be useless, the magnetic force of objects is always maintained at a fixed size. I thought it was impossible, so I didn't try it again."
"Sure enough," Roland turned to Nightingale and asked, "The form of her magic power..."
"It has condensed," Nightingale emerged from the mist and said with a smile, "like a surging blue wave."
Mystery Moon's voice suddenly became excited. "Is it true that I..."
"That's right, your ability has evolved," Roland affirmed. "Without a long period of unremitting practice, it's impossible to understand the key to advancement so quickly. You've performed very well. From today onwards, you will be the sixth witch in the Witch Union to gain an evolved ability. "
"Congratulations." Nightingale smiled as she walked over and patted her head.
"Then can I do more for Your Highness now?" Mystery Moon asked, her eyes sparkling.
"Yeah, too many to count," Roland said with a smirk. "As I said before, your potential is limitless. But … take a good rest first. Your dark eye circles are almost as big as a fist. Let me test your abilities in the afternoon. "
"En!" She nodded vigorously.
After Mystery Moon left the office, Nightingale immediately closed the door and came over. Instead of returning to the table or the floor-to-ceiling window as usual, she flashed close to Roland, pressed his shoulders excitedly, and bent down. Her pale blonde hair fell on his cheeks, making him feel slightly itchy. Looking at her watery eyes and soft red lips, Roland's heart suddenly beat several times faster.
Huh? What's going on! Does she want to do it here … But it's still daytime.
"Tell me the method." Nightingale's words stunned the prince. "Wait … the story seems to be developing differently from what I thought?"
"What method?"
"You didn't need to understand the Theoretical Basis of Natural Science to find a way to evolve," she said excitedly. "With Mystery Moon's exam results, it's impossible for her to understand the content of the book, but you still helped her evolve a new ability! What should I do? Do I also need to practice with a small toy? "
Ugh, so it's about evolution. This request is really regrettable, isn't it? It should be a relief. Roland cleared his throat and collected his thoughts. "I'm afraid that it'll be very difficult for you to achieve a breakthrough in your ability through epiphany."
"Why?"
"According to Agatha, it's possible to trigger evolution by witnessing phenomena related to the ability in reality. Your Mist is so incredible that I don't know its specific principles, let alone guide you to understand it," Roland explained. "If you want to condense magic power, I'm afraid there's only one way to go, which is to master all the knowledge of nature and physics, and advanced mathematics is also a skill that you must be familiar with."
Nightingale's expression immediately collapsed. She walked to the recliner and leaned softly against the back, as if her body had been hollowed out.
After lunch, Roland spent half a day to conduct a comprehensive test of Mystery Moon's new ability.
He named this ability Indefinite Magnetism. Like the previous magnetic bestowal ability, it could be attached to any object and produce periodic changes according to the magic power injected during the enchantment. But for insulators, there was almost no electric current effect.
In addition, her magic power was also the lowest among the evolved witches. She could only light up two Magic Stones on the Sigil of God's Will, which was half less than Maggie's. Moreover, the enchantment ability had a very high demand on magic power. The greater the upper limit of the change of the magnetic force, the longer the duration, and the more amazing the magic power required. After a series of tests, he found that Mystery Moon's new ability was stable as a battery, but it was far from enough to drive a large motor and reach the power of an existing steam engine. He used the DC motor, which was originally assembled for water electrolysis, to transform it into an electric motor for the test, and the result was quite bad. Mystery Moon consumed all her magic power to enchant the motor rotor, but it could only run for half a day, which almost negated its practical value as a source of power.
However, Roland did not disclose this to Mystery Moon. Instead, he encouraged her to continue to practice her new ability and not to fall behind in her studies. For her, evolution was not easy, and any bad news might make her depressed.
Fortunately, ability evolution was not a one-time deal. As long as Mystery Moon could make another breakthrough through systematic learning, there was still a chance to make up for the magic power she lacked.
In addition, Roland also thought of the method of making the Stone of Light with the help of many people, which Agatha had mentioned. If there was a witch who could control or transfer magic power, they could also circumvent the limitation of Mystery Moon's own power.
In the evening, he found Tilly Wimbledon.
"A magic control-type auxiliary witch?" After listening to the prince's description, she pondered for a moment. "No one on Sleeping Island has such an ability."
"Is... that so?" Roland could not help but sigh. It seemed that Mystery Moon could only rely on her own efforts to improve.
However, Tilly's next words made his expression change. "But I know where you can find such a witch."
