Hearing that, Rosvisserâs eyes lit up. She quickly asked,
âWhat is it?â
âSound.â
âSound...â
The sharp light in Rosvisserâs eyes shifted into a trace of doubt.
âCan sound even be used as an attack? And how would she do that?â
Leon spread his hands.
âBefore you actually learned elemental magic, did you think the fire used for cooking could be turned into a fire tornado or all sorts of strange attack forms? And hereâs an even more direct exampleâprimeval magic. Before you learned Soul Severance, Iâm sure you didnât think there could be magic that deals damage based on the other personâs emotional state, right?â
The examples Leon gave were easy enough to grasp, and Rosvisser understood immediately.
The queen nodded, thoughtful.
âIf the attack is carried out through âsound,â then itâs not hard to understand how it could âdamage the wall behind the targetâ or âshatter a stone into powder.ââ
With her two hundred years of experience as a mage, a small hint from Leon was enough for Rosvisser to piece together the strange phenomena from before.
She continued:
âSound makes the target vibrate, and that vibration triggers a much more destructive force, which is why the wall behind the target ended up more damaged than the target itself.
And resonance within sound, when applied to a hard material like stone, causes vibrations at a specific frequencyâthis resonance breaks the stone down from within until it crumbles completely into powder.
The so-called âsoundâ isnât just the physical concept of âsound waves,â meaning the waves produced by the vibration of an object. Itâs like thunder magic in elemental magicâon a stormy day, lightning strikes and splits an old tree...
Can you call that thunder magic? Of course not. Thatâs just a natural phenomenon. Real thunder magic is when you channel your mana outward, imbue it with elemental change, give it a unique form and method of attack, and then make it into thunder.
In simple terms, whether itâs thunder magic, fire magic, or some other elemental magic, the important part isnât the âelementâ at the frontâitâs the âmagicâ at the end.â
So the âsoundâ Leon and Rosvisser had just been talking about wasnât the everyday concept of sound.
More accurately, the proper term would be:
infusing oneâs magical attack with the property of âsound.â
âThatâs what I think too,â Leon said. âThe damage Muse caused twice before can be explained perfectly like this. Which means...â
âNow that we have a hypothesis, we can... test it.â
...
If it was an attack created through the property of âsound,â then Leon could test it in reverse.
The next morning, Leon brought Muse to the training field in the backyard, and even had the servants bring the gold-red gauntlet Rebecca had given her.
Leon didnât hide anything. He crouched down in front of Muse, resting his hands on her shoulders, and said patiently:
âMuse, Dad figured out your magic attribute yesterday.â
Hearing that, Museâwho had been troubled for months over having no attributeâlit up inside.
âReally, Daddy?â
Leon smiled and nodded. âOf course itâs true. You do have a magic attributeâitâs just not one of the five basic elements. Your Grandma Hera was the one who reminded me...â
Leon repeated what Hera had said, along with the reasoning he and Rosvisser had pieced together. The little girl was still too young to fully understand, but Heraâs words made her realize one thing: she did have an attribute, and it was strong and special.
âToday, I brought you here to completely verify your attribute. Work with me, okay?â
Muse nodded hard. âMm, okay! What do I need to do, Daddy?â
Leon took out a specially-made steel plate and set it on the ground. It was about five centimeters thick and looked very tough. Plates like this were stored in the training fieldâs warehouseâleft over from when Noa practiced Thousand-Fold Tempering.
âOh~ Iâve seen this kind of plate before. Big Sis can pierce through several of them in a row!â Muse said.
âMm. So, do you want to try?â
Muse blinked, scratching her head in confusion. âI... I can do that too?â
âYouâve got to try. Hereâuse the gold-red gauntlet Aunt Rebecca gave you.â
Muse took a deep breath and let it out slowly. Once she was ready, she nodded.
âOkay!â
Leon stepped aside, and Muse took a few steps back to put some distance between herself and the plate. She gathered her mana, and a transparent wave of magical energy immediately wrapped around the gauntlet.
Aiming carefully, she pressed the golden thread under the gauntlet. A mana needle shot out, striking the steel plate dead center.
A clear sound rang out, but the plate didnât budge, and the mark the mana needle left was very shallow.
Museâs little face drooped instantly. She bit her lip, standing there awkward and dejected.
âItâs fine, Museâtry it this way.â
In the midst of her disappointment, Muse heard her fatherâs voice. Looking up, she saw he had placed another identical steel plate about half a meter behind the first one.
âDaddy, whatâs this for?â
âJust attack the first one like normal, Muse.â
âOh... okay.â
Though she didnât understand, Muse followed instructions. She aimed again and fired a mana needleâit hit just as before.
Once again, the first plate was nearly untouched.
But just as Muse started doubting herself again, she heard a second metallic clang.
Looking over, she saw the plate half a meter behind had split apart. A very clear web of cracks spread outward from the center, and in the next moment, the plate shattered into several pieces and fell to the ground.
Muse gasped. âWha... what just happened?â
Leon walked over, patted her head, and smiled.
âYou did that, Muse.â
âMe...? How? I couldnât even pierce the first plate, so how could I smash the one behind it?â
âThatâs the special nature of your elementâit can bypass obstacles in front and strike the real target directly, shattering it to dust.â
Leonâs voice was low and even.
âBut even with the gauntletâs boost, it seems you canât control this power very well yet. An attack that can pulverize something behind a shield shouldnât just crack the plate into piecesâit should annihilate it completely.â
âOf course, being able to do this much already exceeds my expectations,â he thought to himself.
Never mind her ageâthis brand-new power was completely unresearched. Muse really was starting from zero.
Right now she could only manage the simplest form of attackâusing vibration to bypass or break down a targetâbut any elemental magic took years to reach full potential. After all, thunder magic started out as little more than tossing a few bolts of lightning from your handâlooked like fireworks °⢠N đ v đ l i g h t â˘Â° from far away. Who wouldâve thought it could be developed into a vessel capable of holding divine power?
So Leon wasnât in a hurry. Just confirming her element was enough for now.
âCome on, Muse, try again.â
As before, he set two steel plates half a meter apart. But this time, he used water magic to fill the air gap between them.
âOkay!â
Muse aimed and fired the mana needle.
The first plate made a thump, and immediately afterward, the cube of water splashed violently. In the next instant, the second plate fell to the ground. It had taken some damage, but far less than before.
âThe vibration was weakened by the water flow, so the damage to the plate was much lower... just as I expected.â
That was enough to confirm it: âItâs âsound.ââ
The father was relieved and quietly proud.
âFrom the start, youâve shown a rare talent and love for music, and now your awakened ability is connected to âsoundâ as well.â
Months after the question had first arisen, Leon finally smiled, satisfied at having solved his daughterâs elemental mystery.
âWell, in any caseâon this new path, keep working hard, Muse.â
