What exactly is the essence of Transfiguration, this is a very important question.

This is not only about the foundation of the universe, but also about whether Transfiguration can meet the growing material and cultural needs of human society, especially the yearning for delicious food.

Regarding this issue, before that, Elena actually had some quite a bit of speculation.

For example, some kind of advanced illusion magic, similar to the legendary pseudo-Niang who is proficient in makeup and falsetto, can deceive the five senses, or the goddess Ilshan, who has insight into the essence of things, dances wildly, dissociates and reorganizes matter, and changes creation in the true sense, or it is a temporary replacement of matter, as if it were a stand-in in Naruto......

Either way, a definite answer will cause divergent speculation to begin to collapse towards a definite outcome.

What's more, once some of her guesses have been confirmed, Elena can do much more than most wizards - this has been tentatively proven in terms of the power of the Explosive Charm, and Grindelwald herself admits that her Explosive Charm has risen to the level of an art rather than a mere enchantment.

If she allowed, Elena could even try to explore and complete some of the puzzles of the century that had long plagued most of the top physicists in the non-magical world.

"Not bad question, my answer is, both – of course, not quite as you guessed. ”

Professor McGonagall nodded in surprise, and replied after a moment's thought.

"Strictly speaking, transfiguration can be divided into three categories, ordinary deformation, semi-permanent deformation, and permanent deformation. But we usually don't mention the latter two, because only a very small number of people are able to hold on to this power - especially permanent transfiguration, which completely changes the nature of things, and the vast majority of them have failed in the case of failure. ”

"If you're still able to choose Transfiguration after you enter sixth grade, you'll be able to easily find that in the Advanced Transfiguration Guide, because that's when we're going to talk a little bit more about the essence......"

Many of the spells cast by the young wizard don't last long.

Even the simplest spell lasts for a few days at most, and in most cases, it disappears after a few hours. Not to mention the complexity of magic like Transfiguration, the duration of their spells may not be enough to cook a bowl of instant noodles.

However, it was clear that Elena was not too happy with Professor McGonagall's answer.

"Professor, I mean...... What happens when we cast the spell?"

According to Elena, at the micro level, the magical world's perception of the world is still a relatively blank field.

As a result, it was difficult for them to imagine how many puzzling and curious questions Transfiguration would produce when it involved the composition of the core of matter—such as what would happen if uranium-238 was turned into uranium-235, and then uranium-235 into krypton and barium—questions that Professor McGonagall was of course unable to answer.

However, it should be easier to answer if you switch to a slightly simpler question.

As she spoke, Elena pointed to the slightly distorted desk in front of her and added an additional sentence.

"For example, if I turn this table into air, or water vapor, mist, it will work......"

"That's the Vanishing Charm, one of the spin-offs of Transfiguration, and we'll learn it in our fifth grade class. ”

"And what if at this time, I lit a candle in the air?"

Elena blinked and whispered thoughtfully, "I mean, I consumed some of the air and replaced it with another gas. ”

"I'm sorry, Miss Caslana, but I don't quite understand what you mean by that latter sentence. ”

Professor McGonagall shook her head with a look of confusion on her face, "But I can tell you that you just need to remember one thing, at least for a long time, that we don't change the nature of things—it's like that poor lectern, and everything you do can end up being reflected on the original object." ”

Doesn't it change the metamorphosis of the essence?

In other words, even if it looks like a lion, it is essentially an inedible piece of wood.

Hearing this explanation from Professor McGonagall for the second time today, Elena frowned and tapped her fingers lightly on the table.

"So, can I understand that it is...... The product obtained through the transformation has an invisible [upper limit of ability], and in addition to the despellation, the power beyond the range of its [essence] can be withheld, which may cause the magic to fail directly? It is as if I accidentally beat the wooden lectern back to its original form. ”

In a sense, you can understand it that way. ”

Glancing at the lectern still in the corner, Professor McGonagall stiffened and nodded reluctantly.

"In this way, part of the reason for the five exceptions mentioned in Gamp's basic transfiguration law is that wizards can't conjure up delicacies out of thin air - crushing and chewing are of course quite serious damage. ”

Elena sighed regretfully and pursed her lips.

That is, just as Newton's laws apply only to the realm of classical mechanics, it would be most accurate to say that Gamp's fundamental deformation law is limited to the realm of classical deformation, that is, the scope of non-permanent deformation.

There is no doubt that the big white pig that looked quite cute just now, that is, a thing that can be seen but not eaten, if you really bite into it, it may become a mouth full of wood slag - although if you think about it carefully, whether it is in her past life or this life, when she was in elementary school, she secretly gnawed on a few bites of the desk for various reasons.

At that time, she thought about how nice it would be if she could turn her desk and pen cap into a mango flavor. Even if you can't eat it, it's a pleasure to lick it.

As for permanent deformation......

Judging by Professor McGonagall's ominous appearance, if nothing else, she should not have mastered it very well.

If Elena wants to change matter in a real way, she may have to turn to the previous Transfiguration professor, Albus Dumbledore, who is tired and wants to retire.

The question is, what kind of justification should be used?

You know, due to some small campus interactions before, Professor Dumbledore's misunderstanding of her is too deep now. Even a relatively normal academic requirement may cause all kinds of suspicious speculations among the elderly.
