Hogwarts, School Infirmary.

As Elena answered, Dumbledore's fingers tapped lightly on the glass test tube.

A handful of shiny black dust swirled slowly, and a little bit of sparkle floated on the top layer—the diamond particles mixed with the graphite dust.

You know, the convenience of magic is that as long as the conclusion is clearly defined, it often takes only one idea to verify it.

There is no doubt that Elena's guess was not wrong.

Because of her previous "incomplete deformation", the original chemical bonds of the wood fibers that make up the main body of the match were completely broken, and the solid dust left behind were mainly graphite crystals and diamond particles with relatively high stability.

"Thank you for your candor, Miss Caslana...... It's a beautiful color. ”

Looking at the diamond particles that rose and fell in the test tube, as if confirming something, Dumbledore took a deep breath, and the folds on his face drew totemic shadows in the midday sun.

"Amazing, quite remarkable, there aren't many wizards in the wizarding world today who can do this level. ”

Dumbledore looked at Elena with his azure eyes and whispered, "But it's also the most terrible and dangerous way...... Miss Kaslana, I suppose you must have felt this yourself, right?"

"Yes, it sucks, Professor. ”

Elena rubbed her temples slowly, revealing a wry smile.

You must know that in her previous life, she was just an ordinary master of quantitative economics, neither a physics department nor a mathematics department, although quantitative economics will be slightly exposed to a certain degree of mathematics courses, but if it is strictly classified according to the economics major, it still belongs to the category of Master of Arts (Master of Arts).

Compared to the dreaded Master of Science, or even the Philosophic Doctor in the Department of Mathematics and Physics, who is almost on the verge of becoming another species, she is naturally not so sensitive to some basic concepts of physics and mathematical phenomena - this is like studying Nuwa's creation of man, who would consider what it is like to pinch two atomic nuclei together?

"Transfiguration, indeed, is a rather complex and dangerous magic. Obviously, I should be a little more cautious and start with the basics first, rather than jumping from the starting point to the finish line all at once. ”

Elena, who was gradually coming back to her senses, said with a look of fear that this was perhaps the weakest she had ever been in her life.

Although she had the self-protection of her body, she interrupted the subsequent magic process in time, but whether it was forcibly disintegrating the chemical bonds and starting to try to modify the substance from the microscopic level, it caused a very serious load on Elena's body.

Even after resting for a while, and drinking the strange potion Madam Pomfrey, she still felt a powerless emptiness all over her body, as if all the cells were left with empty shells, and even moving her fingers felt as if she were moving in the mud.

"Be cautious, but don't be too afraid. Actually, I'm not against you exploring magic and experimenting, but not now. ”

Dumbledore raised his eyebrows, crossed his slender fingers over his knees, and the expression on his face was rather complicated.

As an educator, there is always a subtle feeling that you should retire when facing students who are so outstanding that you can't help but admire them, and this is especially evident when facing Elena.

"I have to say, you're the most gifted wizard I've ever met. As far as I know, there has never been a witch in Hogwarts history who could do something like this in the first Transfiguration class - it's just a little too early for you. You're not ready to step into this field. ”

"Don't worry, I'm not a masochist, it's enough to have such an uncomfortable experience once......"

Elena moved her wrist, looked at the old man sitting on the bed next to her with a serious face, and pouted.

"Ahem, ahem...... Excuse me. ”

At this moment, Grindelwald, who was standing aside, cleared his throat and spread his hands with some displeasure.

"Excuse me, can you explain a little bit first, it's just a failed transfiguration. In my opinion, with Elena's abilities, there is nothing strange about blowing up the desk to dust...... I don't believe it, Albus, you didn't accidentally blow up the teaching props while you were studying—you almost ...... when you were baking bread What does that mean. ”

Grindelwald raised an eyebrow and looked at the black dust that Dumbledore had fallen into his hands.

"This is the remains that Elena left on the table after casting a spell on the match. ”

Dumbledore patiently poured the last bit of graphite dust into the middle of Grindelwald's palm, flicked his fingers on the outer wall of the glass test tube, shrugged his shoulders and whispered.

"So, do you think you can turn it back into a match with your power? ”

"Wrong Transfiguration can lead to irreversible, random magical effects. If you're trying for me to undo the spell, you should at least give me a Transfiguration product that still bears the mark of magic, not a bunch of magical embers that no one knows how to make. ”

Grindelwald glanced at Dumbledore, didn't even bother to draw his wand, and replied with a slight mockery.

While Transfiguration wasn't Grindelwald's forte, he was fairly aware of some basic magical concepts. What makes Transfiguration so dangerous is that, unlike other spells, it has the potential to produce some irreversible permanent transformation when it fails—normally, this kind of reverse spell is almost impossible to do, as every mistake is different.

"Who told you that Elena was transfiguring?"

Dumbledore shook his head, his wand pointing to the wooden decoration on the bedside table, his lips squirming slightly, as if he whispered a rare incantation.

The next moment, the carved bouquet of wood made a soft "poof" sound, quickly disintegrated into powder, and silently piled up on the cabinet—almost exactly the same as the small pinch of graphite dust in Grindelwald's hand, except for the difference in quantity.

"Mr. Otto, you are one of the most ancient alchemists in the world. You should know that once upon a time, alchemy and Transfiguration actually meant the same thing. ”

Dumbledore glanced meaningfully at Elena, whose pupils widened slightly, and his gaze fell back to Grindelwald, this time without selling anything else, directly revealing the final answer.

"In the ancient advanced alchemy, the most basic link turned objects into the most basic form of dust—the dissociation spell. Because it has no spell and is irreversible, it is uniformly defined as black magic by the Ministry of Magic of various countries and sealed. ”

Speaking of this, Dumbledore glanced at Elena helplessly, and there was some tiredness in his voice.

"Obviously, the Ministry of Magic can only prohibit people from using and learning, but it can't stop people from ...... Recreate it. ”
