“What happened? Are you all right?”

Professor McGonagall hurried to Elainna, looking somewhat anxious.

“Elainna’s Transfiguration spell exploded!”

Hermione said sulkily, shaking her head slightly.

As a victim at the center of the "explosion," she was still experiencing some slight tinnitus.

The loud roar and blast of air made her feel as if she had returned to the Hyperion flying base. Elainna controlling the "Valkyrie" armor to break the sound barrier seemed to have caused a similar phenomenon, but the "explosion" at that time was much farther away.

"Well, to be precise, it should be the air making a popping sound—this doesn't count as an explosion."

Elainna corrected earnestly, "Such a phenomenon can occur when gas is rapidly compressed inward or expelled outward."

"So—"

Professor McGonagall raised her eyebrows, a stern expression that reminded Harry, who was sitting in the second row of the classroom, of Aunt Petunia.

Although such a comparison might be offensive to Professor McGonagall, at this moment, the Transfiguration professor was clearly in the brewing stage of some emotional outburst. Apart from Elainna, perhaps no other young wizard could withstand the professor's hawklike scrutiny.

"Could you explain further why the process of turning a pebble into a music box involves... uh, a popping sound?"

"Oh, this is a very wonderful selection range attempt. I selected the blurred space around the pebble."

Elainna said excitedly. She originally wanted to pick up her wand to gesture roughly, but before she could raise her hand, Hermione put down her own wand and instead used both hands to restrain the dangerous element next to her—she still felt a buzzing in her ears.

"We have always speculated... that Transfiguration spells depend on subjectivity when selecting a 'whole' target... for example, when we cast a spell on a sickle, the wizard can flexibly control whether the range of change covers the metal part or the entire sickle... In other words, if the wizard can establish a corresponding overall 'set' concept in their mind, they can extend outward as much as possible."

"Theoretically, that's about it. This content should have originally been covered in your fifth year."

Professor McGonagall said impassively, her gaze still fixed on Elainna. "Our spellcasting target today is a pebble. It's neither a complex combination tool, nor a living creature that can run and jump. I really don't understand what confusion you have about the perception of a pebble?"

"The target of a pebble is certainly very clear, but that doesn't mean it can't be incorporated into other sets."

Elainna said seriously, "For example, I can clearly identify other pebbles, desks, books besides the target object... and then put the remaining pebble and the 'blank space' around it together in one set—this is like when taking a photo, there will always be some background appearing behind the person, and I used the blurred concept of inverse selection, which should include the pebble and the air around it..."

"Get to the point, Miss Kaslana—" Professor McGonagall's tone began to grow impatient.

"Uh, I've finished speaking. Transfiguration will affect the laws of physics, that's the conclusion."

Elainna spread out her hands, saying rather innocently, "Perhaps when we turn 25 cubic centimeters of stone into 40 cubic centimeters of a box, it won't bring too much change to the surroundings, but when we turn 5-6 cubic meters of air plus a small stone into a small music box..."

She raised her hand and waved it a few times in the empty space in the middle of the classroom, clenching and releasing her small fist.

"Due to the appearance of a vacuum zone, the surrounding air will rush in instantly—that's the first popping sound. And when I cancel the magic..."

"The air that you made disappear just now will come back, pushing away the air that filled in, besides making a popping sound, that wave of hurricane that suddenly swept through the classroom must have come from that, right?" Hermione said thoughtfully, she had made up for a lot of lessons recently.

After thinking for half a second, Professor McGonagall also showed a complicated expression.

As a Transfiguration professor, she certainly knew the importance of Elainna's successful "lock-on selection" just now.

Magic has always been a wonderful world that focuses on results, especially with Elainna. If she can achieve it once, then theoretically she has a way to replicate it countless times—which also means that Transfiguration may take a big step forward in terms of range casting.

However, Elainna's "wonderful ideas" are often accompanied by worrying potential dangers.

"Fortunately, at least this time is much better than before. It's nice to have a breeze on a hot summer day."

More than an hour later, as the professors exchanged ideas at the table during lunchtime, Dumbledore smoothed things over gently.

"That's because she controlled it this time," McGonagall glared fiercely at the old wizard who was trying to mediate, refuting in an annoyed voice, "As her magic continues to grow in the future, I wouldn't be surprised even if one day she suddenly turned the water of the Black Lake into air!"

"But, if this spellcasting process is within a controllable range, I believe Miss Kaslana knows the importance of things, right?"

Professor Dumbledore coughed lightly and continued to cut the boiled mutton in front of him.

"You know very well what Miss Kaslana's understanding of 'importance' is."

McGonagall raised her eyebrows and snorted coldly, "In fact, I think you can't ignore certain dangerous signs. Compared to so many terrible dark wizards who have been born in history, the most worrying thing about that young lady is that she can demonstrate lethality within the scope of legality and compliance."

Before speaking, the Hogwarts Deputy Headmistress subconsciously raised her head and glanced at the auditorium door not far away.

On that hard magic wooden door, there was still a terrible knife mark—that was the "Silence" magic released by Elainna last year.

"Alright then, Minerva, what do you think should be done? I believe that child is different."

Dumbledore shrugged rather helplessly, glancing at the bland boiled mutton and potatoes in front of him, and sighed softly.

Otherwise, what else could he do.

He was now just an old wizard who could only obediently eat a low-oil, low-smoke, low-sugar elderly meal.

"Just as we discussed before, in this special period, we cannot, or at least should not, suppress those new voices, especially when they can be foreseen to open a new chapter for the magical world—do you want to limit Miss Kaslana's progress in learning magic?"

"Not—"

Professor McGonagall shook her head, quickly finished the food in front of her, and put a piece of bread into her pocket.

"I just think that as teachers at Hogwarts, we can't always be passively catching up—whether it's 'magical terminals', 'cutting-edge magical theories', 'Quidditch flying skills', 'Muggle natural science'... After clearly seeing the gaps, we should take the initiative to fill in the absence of these contents. I am considering calling on all the professors to spend some energy on advanced studies, so that they can at least understand and surpass the ideas of a twelve-year-old girl."

"Uh—hmm? Call on... all the professors to take advanced studies?"

Dumbledore's eyes twitched, and a ominous premonition rose in his heart.

"Minerva—this is not a pleasant suggestion, and it hasn't reached the point where the professors' knowledge can't keep up. You should consider this idea carefully for a while. The professors are already very tired just completing their daily teaching tasks!"

"Well, but haven't we formed a 'teaching group' now? From the current point of view, the time is actually more flexible..."

Professor McGonagall shrugged, her gaze sweeping across the increasingly large and lively Hogwarts faculty table.

Unlike the past when each course had only one teaching professor, Hogwarts now has too many teachers in the faculty:

There are two professors each for Defense Against the Dark Arts and Transfiguration, and even three official professors for Potions, and there are now one plus two and a half professors for Magical Zoology (formerly Care of Magical Creatures)—and this is without considering student teaching assistants and Mr. Apocalis filling in.

As far as she knew, Professor Flitwick and Professor Sprout had also protested to Dumbledore and the Board of Governors.

Since witnessing the easy course arrangements for the Potions class, they hoped that Charms and Herbology could also add one or two associate professors.

"You said before that the purpose of expanding the faculty was mainly to give the professors time to improve themselves."

The Deputy Headmistress of Hogwarts paused, glanced at the old wizard who was always slacking off next to her, and continued with a serious expression.

"If it's just a disguised vacation, it will only make everyone slack off—I don't want a situation where Hogwarts professors can't even keep up with the students in the classroom one day in the future, that would be too shameful. I plan to try it myself first to see the difficulty and feasibility of the actual operation."

"You should support me, right? Not to mention, Hogwarts will also provide academic standards certification afterwards."

Professor McGonagall glanced at Dumbledore, who was nodding with a stiff smile, stood up and said, "Let's talk in detail tonight!" and left the table directly.

It has to be said that the pressure hidden by the changes caused by Elainna Kaslana was too great.

As a senior professor who has been teaching at Hogwarts for decades, Minerva McGonagall almost immediately realized the terrible learning wave that the "student terminal" could cause—it was not just a "magic book" after course integration, it represented an epoch-making change in students' learning motivation, learning time, and information acquisition. If they didn't change with it, they would soon be "surpassed" by the students.

Perhaps not in terms of pure magical strength or depth of knowledge, but in terms of knowledge "breadth" and the iteration of new knowledge, professors might fall behind.

For example, in the Transfiguration class just now, almost the entire class understood Elainna's "range spellcasting".

Aiming at blurry targets may make the spellcasting result difficult to control, but it will ensure the integrity and wholeness of the spellcasting.

At least there won't be half-spellcasting, such as a rat still retaining its tail when it turns into a cup.

After Neville Longbottom's "strange music box" caused a slight airflow, even Professor McGonagall had to admit that compared to the young wizards with more flexible minds and no old-fashioned thinking constraints, if their older generation of wizards didn't work hard, they might face an embarrassing situation later.

Naturally, after the entire A class of the second year completed the "music box transformation" task, they also received today's second "Excellent" rating.

However, they might find it difficult to achieve the special achievement of "All Excellent All Day" today.

After resting for a while, before the first class bell rang in the afternoon, Elainna and Hermione walked towards the fourth floor of the castle, passing through the corridor of armor displays. The outermost one was the Defense Against the Dark Arts classroom, but everyone's interest was not very high.

Because before the official start of class today, the lower-year students heard a "nightmare" from their respective deans.

Professor Umbridge's course audit passed, and she returned to the lower-year classroom again.

What was even more saddening was that Professor Lupin was no longer there for the second half of the class this time—Dolores Umbridge promised to add some spell content to the course. Given the past performance of this Ministry of Magic official, most young wizards were largely pessimistic about this.

"Don't be so pessimistic, Harry—"

It just so happened that Hermione met Harry, who was complaining in a low voice, in the corridor, and Hermione comforted him with a relaxed face.

"At least we are now using two textbooks, *Magical Defense Theory* and *Dark Forces: A Guide to Self-Defense*. This shows that the content of the two books will be involved in the class later. If she still asks us to copy books, Professor Dumbledore and Professor Lupin won't agree. Apart from those cumbersome and rigid rules, I'm actually quite curious about what perspective and method the Ministry of Magic official uses to view Defense Against the Dark Arts..."

"Curious?" Dean Thomas curled his lips, "Didn't she say it before? Don't cast any spells, that's the best."

"But in the class later, her teaching content must have 'spell' and 'magic' elements—"

Hermione said, winking playfully, and said expectantly, "Then Professor Umbridge will have to come up with some 'real stuff', such as the Ministry of Magic's commonly used spell counters, those should be what will actually be used in the outside world, to deal with dark magic and dark wizards, right?"

Hermione turned her head to Elainna for that last sentence, after all, this little dumpling knew a lot of "inside information".

"Maybe, but even if there really is spell and magic learning, it's not necessarily all good things."

Elainna shrugged indifferently, she didn't spend energy paying attention to the "pink toad's" lesson plan preparation content.

However, she firmly believed in one point—

A dog cannot change its habit of eating shit, and a toad cannot spit out ivory.

Even if Umbridge really prepared some "spell" and "magic" related Defense Against the Dark Arts content, with her understanding of the Ministry of Magic and Umbridge, it probably wouldn't be very pleasant, and it's always right to be vigilant.
