"I'm sorry, I'm so sorry..."

A moment later, in the warm and comfortable bedroom, Aileen apologized cautiously.

"Amber was originally intended to defend against intruders, I forgot to turn off the warning identification..."

"It's okay, it's actually my fault for being a little careless - luckily I know a few household tips."

Not far from her on the large bed, the naked adult witch shook her head with a wry smile, waving her wand helplessly.

The seams of the witch's robes bought from Madam Malkin's Robes for All Occasions were unpicked one by one as if time was reversing, the plain fabric spread out on the bed, and then, with a tap of Madam Abbott's wand, they fluttered like butterflies, reassembling into the shape of clothing.

Of course, unlike the original student robes, the newly woven robes were in the style of an adult woman.

After the new witch's robes were modified, Madam Abbott continued to wave her wand, disassembling the underwear temporarily requisitioned from Hannah, and starting a new round of processing.

Although a certain little witch offered to compensate, considering the style, size, and privacy, it was more appropriate to use her own daughter's.

Of course, compared to the loss of clothing, the magical aftereffects were the real annoyance.

"But... Amber? This is the first time I've encountered this kind of... well, strange magic."

Madam Abbott shuddered uncomfortably, her fair legs curled up on the bed and gently crossed, a hint of red spreading across her skin.

"Well, it's a very powerful magic, I mean—"

Madam Abbott raised her right hand and casually tucked a stray strand of hair behind her ear.

"This isn't something Hogwarts would teach, is it? After all, it seems to me that this magic is a bit beyond the syllabus."

Since her husband's death, she had almost forgotten this feeling.

No, to be precise, she had never experienced such a terrible and shameful situation in her life.

"Uh, I participated in the construction of the theoretical model, but the magical presentation was completed jointly by three other spell masters."

Aileen scratched her cheek, tactfully looking away, pretending not to see Madam Abbott's little movements.

Sure enough, the iron-headed girl's heaven-defying development indicated that the genetic factor must be quite important.

She wondered when her own "developmental period" would arrive.

After a slight pause, Aileen cleared her throat and continued to explain seriously.

"The initial idea came from Amber, using magic to form something like resin fossils, thereby effectively isolating the internal and external space."

"Due to stability and safety considerations, the 'harmless decomposition' magic was added to the subsequent version optimization, which will dissolve foreign objects that do not contain protein components while soaking."

"Soaking?"

Madam Abbott frowned slightly, her body shuddering involuntarily again.

"So those... um, what the hell were those things?"

"Well, highly purified magic power - don't worry, there are no adverse reactions or harmful ingredients."

Aileen glared at a certain iron-headed girl next to her who wanted to say something but hesitated, spread her hands, and explained with utmost sincerity.

"This involves a more complex theory of spatial magic, but you can roughly understand it as a piece of white paper falling into ink, deeply immersed and suspended in it."

"However, since Hogwarts is in the castle magic area, in order to accelerate the immersion, the magic's activity has been slightly increased, which may cause some discomfort."

At this point, Aileen looked at Madam Abbott and said cautiously.

"If you feel a little uncomfortable, why not go to the bathroom to wash your face and 'relax'? I've temporarily released the Amber defense barrier."

Unlike the gentle Amber deployment on the Hyperion, the Amber defense mechanism Aileen set up in the bathroom was significantly more crude.

Whether it's the forced decomposition of personal belongings, or the ubiquitous high-speed soaking... these processes will undoubtedly cause a fairly clear feedback on the human body.

And the key point is that, in order to maintain and strengthen the sealing effect, the purified magic power activated by Amber is in a high-speed flowing state, the degree of stimulation is roughly a hundred times greater than what Hermione had previously experienced.

Even if she rushed into the bathroom to salvage the situation the moment "Amber 2.0" was activated, the aftereffects of those few seconds might take several hours to completely dissipate.

"Or... should I ask the kitchen to make some ginger tea or something... I heard Professor Dumbledore say that Amber might trigger 'spatial claustrophobia' or something..."

As an underage little witch who is not yet thirteen years old, Aileen found it difficult to find a suitable way to express her concern for the moment.

After all, Madam Abbott wasn't an iron-headed girl, and if she accidentally revealed some knowledge reserves, she might be permanently blacklisted.

Fortunately, there was a perfect figure in Hogwarts who could help bear most of the blame.

"No need, I just need to rest for a little bit."

Madam Abbott waved her hand weakly, glancing at Aileen, whose eyes were clear.

If she remembered correctly, this child seemed to be a little younger than Hannah, and even if she was full of shame and anger, she wouldn't lose her composure in front of two children.

However, in this embarrassing situation, she'd better find some other topics to temporarily divert the children's attention.

Oh, right - why not ask this child about her studies.

Madam Abbott thought for a moment and pointed to the stack of booklets she had just sorted out.

"...New spatial magic, Professor Dumbledore? So this is what Hannah was talking about... um, magic derived from mathematics?"

"Eh, new magic derived from mathematics? No, this is actually—"

Aileen blinked, about to deny it subconsciously, then suddenly paused.

Um, wait?!

Magic derived from... mathematics?!

Magic originates from the wizard's perception, an abstract force with vague cause and effect.

And in a sense, this also seems to describe mathematics, and if this is used for deductive reasoning.

Then, mathematics - oh no, theoretically all "invisible" natural sciences should have corresponding magical forms.

After a few seconds of silence, Aileen nodded thoughtfully and said softly.

"Um... you're right, Amber should indeed be derived from mathematics and other subjects."

Professor McGonagall's optimization of Transfiguration is based on the magical side, with magic as the main body and scientific thinking as a tool.

But conversely, if science is the main body and magic is the "manifestation" tool, it is not necessarily a very wonderful path.

Just like Benitez took the initiative to enter the magical world.

The non-magical world also has a way to gallop towards the realm of magic, and not just uniformly enchanted enhancements.

Perhaps, this is the deep-seated reason why Dumbledore took the initiative to leave Hogwarts—

To open up a new field of magic and science in the absence of traditional constraints.

"New type of magic derived from mathematics?"

Madam Abbott repeated softly, inexplicably asking an extra question.

"Then - Hannah, can you cast this spell too? I remember you also took this year's math class..."

"I..."

Hannah blinked a little uneasily.

As a reserve Great Arcana, she certainly knew what type of magic Amber was.

That was a super-difficult compound magic completed by several top wizards, not new content derived from mathematics.

"Hannah hasn't completely mastered this magic yet, but she has successfully released it before—"

Before Hannah could figure out how to muddle through, Aileen put her arms around Hannah's shoulders and said with a friendly smile.

"Aileen, you..."

Hannah glanced anxiously at Aileen, whose eyes were shining brightly.

They had known each other for so long, and whenever Aileen showed such an expression, it was usually not a reassuring sign.

"Don't worry, I believe you'll be able to learn this magic soon, and then you can teach it to your mother."

"Um, in short, let's go back to the common room first? Old Man Benitez is still waiting for me to take him on a tour of the dormitory."

"There's also a bonfire party after the bed check. There aren't many opportunities for outdoor barbecue parties like this, and being a few minutes late is a huge pity."

However, on the other hand—

Aileen's gaze swept over Madam Abbott, who was cleaning up the water stains after redressing.

Um...

Learning how to cast the Amber magic?

Madam Abbott's idea seems a little dangerous?

But...

Aileen glanced thoughtfully at the buxom landlady of the Leaky Cauldron not far away.

Speaking of which, she seemed to have discovered another completely blank area in the magical world, and perhaps a new industrial chain could be born.

The added effects of Amber 2.0 are much stronger than she imagined, and perhaps her subsequent ideas should also be opened up.
