The staircases and corridors of Hogwarts mostly held no distinction for Aileen.

However, in certain locations with clear signs, she could still discern her direction—she merely had a poor sense of direction, not amnesia or intellectual deficiencies. If the staircases at Hogwarts weren't constantly changing, she would have been able to independently roam at night long ago.

"We're supposed to be going to History of Magic now, right? Why do I need to jump one step forward here?"

Aileen stopped, looking warily at the little beaver beside her who was responsible for navigation.

After leaving the Great Hall, they had separated from Hannah and Luna, each heading to their respective classrooms on the AB class schedule to prepare for class.

"Professor Binns doesn't take attendance. As for why you need to jump forward—"

Hermione said, tapping her toe on the step, and the seemingly solid step instantly caved in.

"Someone has fallen here many times. If you don't jump forward one step, you'll repeat it again today."

"Wait, are you planning to skip class?! This is—"

"Compared to occasional absences, I think it's more important to communicate with Professor Dumbledore in a timely manner."

Hermione looked into Aileen's eyes and said calmly, "Anyway, we can study History of Magic from books ourselves, but regarding certain people secretly brewing alcohol in the castle and stealing drinks, I think it's best not to delay too long, lest you secretly destroy evidence or fabricate a chain of evidence."

"Uh. Granger, in your eyes, am I the kind of person who would distort the truth and evade mistakes?"

Aileen said with a pained expression, never having imagined that trust between people could be so fragile.

"Besides, you're skipping Professor Binns' class. Professor Binns is such a dedicated and tirelessly respectful professor. If we miss his History of Magic, wouldn't that be a great offense to the living and the dead? I don't think we should..."

"...Are you coming up or not?"

Hermione looked coldly at the drama queen performing there, raising an eyebrow.

"Oh." Aileen's cowlick drooped dispiritedly.

They arrived at the entrance to the Headmaster's office, hidden behind a huge stone beast.

The Headmaster's office at Hogwarts was located in a separate small tower, and like the common rooms of the four houses, you had to give the correct password to pass through the stone beast's barrier and reach the oak door of the Headmaster's office via the automatic rotating staircase behind it.

"Fizzing Whizbees," Hermione whispered as they walked in.

As the stone beast came to life and jumped aside, Aileen's last bit of hope vanished.

The password at Hogwarts changed periodically, which meant that Dumbledore had told Hermione at least a week's worth of passwords.

This was not surprising, since in addition to being the Headmaster of Hogwarts, Dumbledore, as 【o5-3-Pope】, was also the "Major Arcana Guardian" of the pre-justice Miss – and what made Aileen even more helpless was that the trio were her "supervisors".

Following the spiral staircase to the top of the tower, Hermione knocked on the shiny oak door.

The door opened silently, and they walked in.

The Headmaster's office at Hogwarts was probably one of the most familiar places for Aileen.

"Hmm? Miss Granger, Miss Kaslana?"

Dumbledore, sitting behind his desk, adjusted his glasses and asked softly, puzzled.

Not far away, Grindelwald sat comfortably in an armchair by the fireplace, his gaze still fixed on the pages of the book in his hand.

However, Aileen knew that at least half of the Dark Lord's attention was on them; he was just lazy.

Because of Grindelwald, Aileen could almost walk sideways in the office. If Dumbledore's and her opinions clashed, the retired old wizard would usually stand on her side to help smooth things over. In a two-on-one situation, she wasn't afraid of the old turnip at all.

However, this time was different from usual—this time she was turning herself in.

"I secretly drank again, this time it was homemade..."

Aileen touched her nose with some guilt, looked at the two old wizards, and tried to squeeze out a cute, adorable smile.

"The raw material is potatoes planted by Gryffindor, and it's 'Vodka' that's being brewed. Judging from the taste and quality of the product, it's quite successful. This way, we don't have to worry about potatoes being stockpiled and deteriorating, and Hogwarts has another derivative product... This should be... good news, right?"

Under the gaze of the two old wizards, Aileen's voice grew softer and softer.

Hogwarts students, when converted to the non-magical world, are mostly in middle and high school, which in Eastern culture is about the age when they can drink alcohol, not to mention that special distiller's yeast like *kuchi-kamizake* is made by girls of this age.

However, unlike the East, in Western societies, the ban on underage drinking is even stricter than the ban on sex.

At least judging from the expression of the first generation old Dark Lord, who closed the book and went from a lazy posture to sitting upright, she was obviously in big trouble.

"I'll leave it to you."

Dumbledore sighed and shrugged at the solemn-looking Grindelwald.

It was indeed the responsibility of the headmaster and professors to deal with problem students. In any school, when faced with a mischievous little devil who repeatedly refused to be taught or who made mistakes knowingly, notifying the parents was always the most effective and simple solution.

A few hours later, Jose Benitez would naturally receive a letter from Hogwarts.

And before that, "Otto Apocalypse" was qualified and had reason to discipline "Theresa Apocalypse".

"I remember we talked about it before, about the issue of drinking..."

Grindelwald crossed his fingers and said unhurriedly as the firelight flickered in the fireplace.

"If you really want to taste the taste of alcohol, you can directly ask, and as long as I, Jose, or Dumbledore accompany you, we won't completely forbid it like those rigid Muggle, so can you come up with a suitable explanation now?"

"Didn't I just say that the stockpiled potatoes can..."

"Are you short of money? Change the reason—there's no need to say this kind of thing to fool Albus."

It would have been better if Grindelwald had been a little more fierce. Aileen was most afraid of encountering this slightly disappointed tone of accusation.

For some reason, even though there was no blood relationship between the two, and they had only known each other for a little over a year, sometimes Aileen would really have the illusion that this old wizard was her grandfather—Dumbledore's treatment was obviously much worse, as long as he wasn't angered to death by her.

As for the reason, perhaps it started with that half-cooked, dark roasted potato?

"Okay, the reason is that I wanted to taste the taste of vodka brewed from Hogwarts potatoes."

Aileen said with a shrug, "Besides, drinking is about the atmosphere. Drinking under your gaze is like taking medicine."

"Is it tasty?"

"Huh?"

"I mean, how do you feel after tasting it?"

Grindelwald grinned and repeated it again on purpose, asking curiously.

"Vodka brewed from Hogwarts potatoes, which is better, the alcohol of the magical world or the non-magical world?"

"Not tasty—"

Aileen glanced at the old wizard and pouted unhappily.

"I heard that there is a high-concentration vodka in Poland called 'Spiritus', which uses multiple distillations to reach an alcohol concentration of 96%-97%. From the information I have on hand, it uses some basic operations of alchemy, but the distillation processes I came up with are not enough."

"Ninety-six percent? So you plan to drink that?"

Grindelwald couldn't help but twitch the corner of his mouth. In his impression, the strongest alcohol he had ever drunk was only about 30-40 degrees.

"Of course not, that's not for drinking directly—"

Aileen spread her hands and explained, earnestly popularizing science for the old man.

"In the non-magical world, 'Spiritus' is mainly used for the base liquor of cocktails, or for medical disinfection, industry, and even as an alcohol fuel in some special cases... If I were to make that, then I should carry some with me as—"

"...As what?" Grindelwald frowned, looking at the white-haired dumpling that suddenly stopped.

Whose bad habit is this of saying half a sentence and selling off?

Okay, Dumbledore occasionally has this hobby of being a riddle person, but that guy at least won't break off so abruptly.

But Aileen wasn't really deliberately selling off this time.

In her original idea, she wanted to say that it was used as a seasoning and survival tool for wild cooking.

But just as the words were about to come out, Aileen suddenly flashed back to the question Grindelwald had asked her earlier.

"I know what the right explanation is. The answer is: wizard's alcohol."

Aileen changed her tone and turned to look at Dumbledore, explaining proactively before Grindelwald could ask.

"The alcohol of the magical world and the alcohol of the non-magical world have no essential difference in terms of their own quality."

"It's like a wand is just a small wooden stick in the hands of ordinary people, but it's completely different in the hands of a wizard. By the same token, wizards have a way to make 'Vodka' work, or use various items to enhance magical effects. I call it 'spellcasting materials'."

Even with magical, unreasonable magical powers, the magical world still follows some basic natural laws.

Perhaps wizards can create powerful explosions with just the power of spells, but explosives detonated by spells are definitely stronger than simple Explosion Charms.

Since accidentally blowing up half of the History of Magic classroom last year, Aileen has kept her promise and behaved herself in the castle, temporarily shelving her research on spellcasting materials and enhancing spellcasting, but that doesn't mean she has forgotten what she had verified.

High-purity "Spiritus" can simultaneously enhance "Fire magic" and "Water magic".

"Compared to explosives, Vodka is undoubtedly very reasonable in both the non-magical world and the magical world."

Aileen's thinking became clearer and clearer. This was not comparable to those dangerous explosives or other chemical substances.

"Gryffindor House and the Destiny Group have stockpiled a large number of potatoes, we can really start from this aspect first—as for the problem of underage students drinking that you are worried about, we can find ways to avoid it through the threshold of magical courses and the supervision of the prefects..."

She looked at the two old wizards with some excitement, and a brilliant world instantly unfolded in her mind.

"Spellcasting materials? Oh, this explanation... I think it's very reasonable."

Grindelwald raised his eyebrows slightly, nodded noncommittally, picked up the book and sat back in the armchair.

"Since it's academic research, and Vodka is not tasty, then this matter is naturally another matter—as for the curriculum content, school and academy planning, and student discipline, these should be matters for the Headmaster of Hogwarts... Albus, why don't you listen to her, I think it seems a bit interesting... Of course, just a personal suggestion..."
