Louis' perspective changed again, and his eyes went completely white.
This is not the first time I have experienced this, and it is probably the next memory that needs to be replaced.
Sure enough, it took him a while before he could see the scene in front of him clearly again.
Arctus Black has returned to Hogwarts, but this time, his identity has changed significantly.
"The Transfiguration Spell is a fascinating and dangerous spell that can turn inanimate objects into living things, and vice versa, just like this."
He pointed gently at the little white mouse on the table. The white mouse was placed on the candle holder, its hind legs stood up, and it looked curiously at the students in the audience.
Arctus muttered a spell in his mouth, and the wand shook slightly. The next second, a beam of light shot out from the front of the wand and hit the mouse's body.
In the shocked eyes of the group of first-year students, the mouse's body changed. Almost instantly, a silver goblet replaced the mouse that once existed.
"This is the Transformation Spell. Of course, it is a very basic spell. The Transformation Spell has a wide range of uses. It can even conjure things out of thin air. If used properly, it can be used in battles. Of course, this requires you to be very strong in magic. control."
"Then, here comes the question. Although the transformation spell is very powerful, it is not omnipotent. So what can't it change?"
Arctus put this question on the blackboard and looked at the students below with some expectancy. He knew in his heart that this question was somewhat difficult for first-year students who were new to magic education.
There was silence in the classroom for a minute. When Arctus was about to announce the answer, he raised a hand timidly.
"Yes...it's food, Professor. Because this is one of the five exceptions to Gamp's basic law of transformation..."
"What's your name, kid?"
There was a hint of relief in Arctus's voice, and the boy was a little embarrassed.
"Kinnekel, Ginnekel Shacklebolt, I mean Gryffindor, Professor Black."
Louis, who was watching, recognized it at a glance. This was probably Kingsley's ancestor. However, at that time, the genes of white people were still very pure, and the Shacklebolt family did not know from which generation it began to develop in a multi-ethnic direction.
"Five points to Gryffindor Shacklebolt!"
"Very good. Gamp's basic deformation law is something that has just emerged in recent years. No one has mentioned it at that time. Although it is relatively new, the point it conveys is the most direct. I can conclude that, This law will become the basic law of transformation spells in the magical world."
"Professor, I have a question." A girl's voice raised her hand and asked, "Since Shakur just mentioned the five exceptions, and food is one type, what are the other four?"
"Transfiguration cannot be made out of nothing." Arctus continued, "This sentence is very contradictory, right? But you have to think about it carefully. What I just said about conjuring something out of thin air must be logical. It is the original environment. It should be something that can exist, not just anything.”
"Okay, third, the living and dead objects in the transfiguration cannot be permanently transformed. We turned this white rat into a goblet through magic attachment, but it is still alive to a certain extent. As time goes by, When the magic power dissipates, it will return to its original form. Please remember that death is an existence that can never be conquered."
When Arctus said this, some students began to whisper below. The word death seemed particularly distant to wizards of their age.
Among a group of chattering students, a student wearing a Gryffindor robe seemed unusually calm.
"The fourth point is also the most critical. Transfiguration cannot create magic items, including all the items and materials used in your alchemy. So don't think that you can sneak away alchemy after learning transfiguration. There is no way."
At this time, laughter could be heard from time to time. Arctus's teaching method was quite strange in the eyes of the older generation of teachers.
"Last one, the Transformation Spell cannot conjure something that doesn't exist."
This was also the first time for Louis to hear a complete explanation of Gamp's Law of Transformation. He had always heard Hermione mention that food was one of the five exceptions, and it was the first one, which seemed particularly important.
But from his perspective, he observed the Gryffindor student. When Arctus began to explain Gamp's basic transformation rules, he listened particularly carefully. He seemed to have a level of concentration that was inconsistent with his age.
After explaining the basic principles, Arctus' class entered the practical part. However, just like the young wizards a thousand years later, the students at this stage were new to the art of transformation and their performance was not very good.
The bell rang soon after class. In ancient Hogwarts, a class was relatively short, and students spent most of their time participating in outdoor activities. At that time, the Black Lake was not closed to water, and most of them As soon as the students heard the bell, they rushed out to play.
The student who was extremely focused at that time was the only one left in the classroom, and Arctus also noticed her presence at this time.
"Do you have any questions? This classmate?"
It's rare to see such a studious first-year student in the classroom, and Arctus is quite serious.
But she didn't answer, just looked at him quietly.
Instead, Louis felt a little weird about this scene, but also felt familiar. He seemed to have seen this kind of aura in others before.
"Classmate?" Arctus called again, and this time the student finally spoke.
"Is death really unconquerable? Professor Black."
"What did you say?"
Arctus couldn't help but tremble when he heard this sentence. Death is a topic that all wizards avoid talking about. They will consider it taboo, but this sentence is a bit unbelievable when it comes from a first-year freshman.
But he didn't have time to think about it, because the next second, the classroom door was knocked open by a fifth-year Slytherin student.
"Professor Black, um, the Headmaster of Hufflepuff wants you to come over. It seems to be about Professor Ravenclaw."
"Okay, Buffent, I'll be there right away."
Arctus quickly packed up his things and rushed towards the classroom door. When he turned around to see the student's expression, he had already disappeared.
He shook his head helplessly. Hogwarts had been founded for almost fifty years, and it had brought out dozens of students with all kinds of personalities, which was not uncommon.
Louis followed Arctus Black's perspective and left the Transfiguration classroom. However, no one noticed that at the outer corner of the Transfiguration classroom, the girl was leaning on the stone railing.
"Hogwarts? I'm sorry, Barrow, the thing you love is my painful memory, then I will destroy it with my own hands."
