Hogwarts: Is this junior good or evil?

Professor McGonagall didn't care about her disciples' thoughts, but unfolded a magazine called "Transfiguration Today". Yang Tian peeked at the date of the magazine and found that it was published half a year ago.

Professor McGonagall said gently, "At this gathering, we will first discuss an exploratory article. The idea in this article is very novel, but due to the lack of supporting evidence and practical parameters, I prefer to call it a fantastic idea."

"This article is called 'The Beginning and End of the Vanishing Spell'. It discusses where the objects that have been cast go after the Vanishing Spell is cast, or how they exist. This article should be the imagination of a fan who is obsessed with Transfiguration. The reason why I bring it up for discussion with everyone is that I hope everyone can broaden their horizons and liberate their minds."

Professor McGonagall's words immediately attracted the attention of the students, including Yang Tian. Although it seems that the Vanishing Spell is beyond the scope of Yang Tian's study, and he has not yet learned it, it does not affect his strong interest in this spell.

"The Vanishing Charm is a fifth-year Transfiguration course. This Transfiguration Charm, which can make living or inanimate objects disappear, is one of the most difficult spells that appear in the Ordinary Wizarding Level Examination. The difficulty of this spell is not too difficult to learn, but when it comes to the number of people who have truly mastered the essence, there are really only a handful of people who can count on one hand." Percy spoke first, and then he raised his head proudly and continued:

"For example, snails, an invertebrate, are not very challenging, but mammals like mice are much more difficult. I have now completed the disappearance spell for mice, and am now pursuing the more challenging cats. To be honest, this requires talent and hard work, and I think I need to work harder." The words seemed humble, but in fact they were showing off.

Elena from Slytherin glanced at Percy with dissatisfaction, and calmly brought the topic back on track: "I remember Professor McGonagall said when she was teaching this lesson that things that disappear become nothingness, or in other words, everything. Later, I also guessed that nothingness and everything seem to represent zero and infinity, which are two completely opposite meanings. I was confused about this for a long time at the time."

Violet took the Transfiguration of the Day from Professor McGonagall and read it carefully before continuing with a hint of doubt: "According to the idea of ​​this article, after the Vanishing Spell is cast, the object is vaporized and becomes part of the air. This statement is far-fetched."

Then, Violet drew her wand and shouted at her chair, "Evanesco." The chair disappeared instantly. Then, a restoring spell was cast, and a piece of parchment fell down.

Violet said wisely: "Look, after the restoration spell, it is still the most essential parchment, not the chair. So the theory of vaporization is somewhat untenable. I think the word essence is very important. I prefer to believe that this is a constraint of the material structure. The appearance changes but the essence remains unchanged. This also conforms to the definition of Transfiguration."

"This is the mainstream view now. But professor, can you tell me your understanding of what Elena just said? I feel that your opinion seems to be inconsistent with the mainstream view." Angelina asked outspokenly.

Everyone also looked at Professor McGonagall hopefully, waiting for her answer.

"It's hard to describe." Professor McGonagall seemed to be immersed in her own perception. She thought slowly and answered, "It's the wonderful feeling brought by casting the Vanishing and Summoning Charms over the years. It's as if it has completely dissipated without a trace."

"But it seems to have a lot of material charm. And the restoration spell is more like... well, how to put it? Reverse time? Return to the state when it was just made. It's a feeling that is hard to describe."

Everyone listened very attentively, and seemed to be experiencing that mysterious and wonderful feeling.

But only Yang Tian's brain seemed to be struck by a thunderbolt. In this month, his Transfiguration made rapid progress under the guidance of Professor McGonagall, and coupled with a month of reading books, the theoretical knowledge in his mind was extremely rich.

However, no matter how rich the theoretical knowledge is, it is useless without practice, so his study of transfiguration still only remains on the surface and he is unable to master it.

But today, the discussion about the Vanishing Spell was like a magic needle, threading together the previously scattered pieces of Transfiguration knowledge into a perfect line.

At this moment, in his mind, scenes from the beginning of the transformation of non-living things flashed like a movie. Yang Tian was stunned on the spot, his eyes were empty.

After Angelina discovered something was wrong, she wanted to slap Yang Tian to wake him up, but was stopped by Professor McGonagall's stern look.

As time passed, Yang Tian's empty eyes gradually focused and became brighter. Finally, an incredible glow appeared on his face.

He seemed to draw out his wand unconsciously, and under the influence of the magic power in his body, the ancient wand emitted an ancient glow.

The magic wand just waved lightly in the air, and a dragon bamboo appeared out of thin air, exuding vitality.

With another wave, Longzhu instantly lowered its body, coiled and transformed into a short-nosed sea snake.

With another wave, the short-beaked sea snake disappeared instantly; but it reappeared with another wave.

Yang Tian waved his magic wand a little further away, and a tree-guarding bowtruckle appeared out of thin air.

With the tap of the magic wand, the Bowtruckle and the Short-nosed Sea Snake kept changing and eventually turned into each other's appearance.

With another tap, the Bowtruckle and the Short-nosed Sea Snake kept changing their previous appearances in reverse, and finally disappeared. Yang Tian looked at the magic wand in his hand with great enthusiasm, feeling inexplicably happy.

The seniors around them opened their mouths wide, their eyes bulged, and they looked like they had seen a ghost. The two girls suddenly realized that their expressions were indecent, and they quickly controlled their expressions, but they still looked at Yang Tian like he was a monster.

When Yang Tian began to cast the spell, Professor McGonagall exclaimed in a low voice as the scene changed: "Summoning Spell... Transfiguration Spell... Vanishing Spell... Restoration Spell, but why is it a snake and not a bamboo?... Summoning Spell... Transformation Spell... What kind of spell is this? Why is it like this?"

"Actually...actually the spell was cast silently the whole time?" Cedric exclaimed in disbelief.

Although his voice was not loud, it was like a small stone thrown into a lake, and the classroom suddenly went wild. There were only seven people, but he shouted with the momentum of an entire class.

"Merlin, what do I see?"

"You must be kidding. What kind of spell is that at the end? I've never heard of it before."

"You've already learned the fifth-grade curriculum? This is incredible."
