The Burrow, the Weasley's home.

Just a few minutes later, the owl squadron left as quickly as it had come, taking away the joy in the living room.

Ron Weasley turned his head blankly to look at the pile of parcels stacked next to the table. The only difference between them and ordinary parcels was the striking silver-white wing emblem on each one.

The silver-white wings stretched backward, with a deep blue background like the sky.

"Big Sister's will," Ron murmured.

An ominous premonition suddenly arose in his heart. Seeing this familiar symbol halfway through the summer vacation filled him with an unconscious sense of dread, an oppression similar to but also distinctly different from that he felt when facing his mother.

Whenever Big Sister's emblem lit up, it usually meant someone was going to be in trouble.

And as the packages in the pile were opened one after another, this ominous premonition turned into despair, descending upon the Burrow.

Books, all books.

If one were to classify them in slightly more detail, they could be accurately divided into magical textbooks, non-magical textbooks... and complete sets of workbooks and summer general knowledge quizzes, as well as some recommended reading and knowledge-expanding reference books.

Every Weasley child received such a gift, the whole family accounted for, without a single exception.

George Weasley and Fred Weasley had already turned to stone, frozen in their respective seats, their pupils unfocused, appearing bewildered and confused. They really didn't know where they had offended Miss Kaslana.

On the other side, Mrs. Weasley had taken the children's letters at some point and said in a joyful tone.

"Professor Dumbledore and Elena, how thoughtful of them!"

"These are all the children's textbooks, teaching aids, summer homework for the next semester, as well as the course adjustment direction after Hogwarts' new curriculum reform next year, Arthur. This is not only saving the family a huge expense, but also a kind of emphasis!"

"Oh, and there's Ron's, hmm... it's actually a study plan specially tailored according to his Quidditch training schedule."

Listening to his mother's voice, Ron's eyes gradually began to lose focus as well.

Percy Weasley glanced at his petrified brothers, shaking his head with a sneer in his heart.

"What a bunch of unambitious fellows. This is a shortcut to a higher place, and they still have the leisure to complain."

"But come to think of it, even if the courses will be adjusted a bit next year, they shouldn't be too difficult. It's just adding some general knowledge courses that Muggles also learn. This kind of help is probably more symbolic than substantially beneficial."

Percy looked at the new courses on his envelope, glanced at his two brothers beside him.

Just as he thought, whether it was Bill or Charlie, they were mostly just surprised about having to return to Hogwarts for further study. As for what courses they would actually have to learn, most of them didn't show much concern.

They could get all A's in magical courses. How difficult could some introduced Muggle knowledge be?

At the same time, the names of those new courses and reference book lists were also presented in his eyes. Percy muttered softly.

"New core subject, mathematics. As for the reference materials..."

…………

" *Calculus* by Fichtenholz, *Mathematical Analysis* by Zorich, *A Course of Higher Mathematics* by Smirnov... Oh, the school's after-school exercise book, *Problems in Mathematical Analysis* by G.N. Berman?"

London, England, the Granger's home.

Mr. Granger looked at the book list in his hand, checking the names of the books that appeared in the living room with his daughter.

Not long after the start of the vacation, Hermione begged Mr. Granger to hire a tutor to tutor her in mathematics.

Unfortunately, in less than one lesson, Mr. Granger discovered that this so-called outstanding graduate didn't seem to be able to meet his daughter's needs very well. According to Hermione, the tutor couldn't even explain the most basic calculus.

What made Mr. Granger even more incredulous was that this seemed to be the basic teaching arrangement for Hogwarts next semester.

And with his father's explanation, and several correspondences with Elena, Hermione finally understood.

It turned out that the "ordinary Muggle middle school" mathematics course that the little white-haired ball was talking about didn't refer to the standard in the UK, but rather the learning content of those non-magical students in the former Soviet Union on the other side of the continent.

Unfortunately, at this point in time, the Soviet Union had just disintegrated, and there weren't many experts flowing to the UK.

Fortunately, as an excellent Cambridge biology master's student and a well-known dentist in London, Mr. Granger's foundation in mathematics was quite good, and tutoring his first-year daughter wasn't too difficult.

However, due to his busy work schedule on weekdays, he could only let Hermione study on her own for most of the time.

After learning about the course adjustments for the next semester at Hogwarts, and the basic learning level of the magical world, the anxiety in Mr. Granger's heart dissipated a lot - the magical world was indeed different, starting with advanced mathematics in the first year.

In this way, when Hermione graduated from that magic school, whether she wanted to work in the magical world or continue her studies in non-magical universities, it would be extremely flexible, and she wouldn't have to go all the way down just one path.

The only strange thing was...

Mr. Granger put down the letter in his hand, frowned slightly, and muttered to himself.

"Why are these books all works by former Soviet mathematicians?"

"Could it be that the professors who will be teaching Hermione next year have all studied in the former Soviet Union? Although it seems that they are slightly ahead in the field of mathematics at present, the problem of language barriers is also solved by magic..."

…………

Scotland, on the shores of Loch Lomond.

Just after eight o'clock in the morning, Dumbledore's figure appeared in the orphanage on time.

And in front of him were Elena, who had packed her luggage and was saying goodbye to Father Benítez, and the first-generation Dark Lord, who had changed into a sophisticated dark trench coat and was quietly watching Elena and Benítez.

Dumbledore nodded to Benítez, turned his head to look at Elena, and said in a gentle tone.

"It's about time, Elena, we should set off. Have you packed all your things?"

"Don't worry, José and I packed everything for this girl last night."

Grindelwald grinned and patted Benítez's broad shoulders with emotion.

"Don't be too sad, I will take good care of Elena. If you miss her later, I still have the right to open the back door for you as the castle administrator and part-time substitute professor at Hogwarts - as for now, I should accompany her to..."

"Ahem, Gellert, what we mean is - me and Elena."

Before Grindelwald could finish speaking, Dumbledore politely cleared his throat, pointed to himself and Elena, and slowly added in a calm but polite tone.

"Newt is hiding in a safe house in Dorset, so you can't go."

"Albus, you're not kidding, are you? This joke isn't funny at all..."

The smile on Grindelwald's face gradually disappeared, and his eyebrows slowly raised. One second to remember the mobile terminal 『→m.\』 to provide you with wonderful \ novel reading.

Dumbledore blinked his eyes, glanced meaningfully at the stiff-faced first-generation Dark Lord, and said calmly.

"Mr. Scamander has quite a few strange creatures there. I have to admit, sometimes the intuition of some magical creatures is indeed something we can't understand. And the most important thing is, do you remember the first time you... um... anyway, today is Elena's first time at Newt's house, I think it's best not to complicate things."

"...Alright."

Grindelwald looked at Benítez, who was beside him looking dazed, and the heartless little dumpling who had a look of schadenfreude on her face, sighed deeply, and finally didn't insist on continuing. Although he wasn't afraid of Newt, that guy's intuition was too sharp, and besides, Newt Scamander's animals were really difficult to deal with.

And on the other hand, Grindelwald naturally knew what Dumbledore was worried about in his heart.

After all, he had suffered more than one or two secret losses from Newt Scamander back then. If he had any intention of revenge, not to mention him doing it himself, or mobilizing some Hyperion, even if Grindelwald only relied on the newly gathered followers under his command, it would be enough to completely flood that area with spells.

The current first-generation Dark Lord had lowered his bottom line a lot under Elena's influence.

Not to mention, Grindelwald had left Dumbledore with too deep an impression in terms of holding grudges and being willful.

"Albus, it was so many years ago, I wouldn't be so petty. Then I'll say goodbye to this girl."

Grindelwald shrugged helplessly, thought for a while, walked up to Elena and squatted down, and patted the girl's head.

"Remember not to starve yourself while staying at Mr. Newt Scamander's house. If you see something you like to eat, eat more, you're still growing - if you encounter a more powerful magical creature, don't be afraid, just secretly write it down first, and after school starts, I'll help you find a way."

"The wasabi, minced garlic, millet pepper, soy sauce, balsamic vinegar, oyster sauce, pickled peppers, bean paste, pepper, peppercorns, and all kinds of strange spices you wanted, I've all put them in your suitcase for you, I originally wanted to give you a surprise... but looking at the current situation, I can only tell you in advance, the password to open the kitchen seasoning space is -"

Grindelwald glanced at Dumbledore not far away, took out his wand and waved it gently.

Immediately afterwards, a layer of invisible ripples instantly enveloped the two of them, isolating all sounds within it.

The first-generation Dark Lord leaned close to Elena's ear and said softly.

"Stew that Niffler."
