Hogwarts: My name is the Unforgivable Curse

“First, let’s understand the definitions of these three classifications.”

Professor Kettleburn conjured up a blackboard and wrote on it: "Bloodline type means that the magical structure of this magical creature is directly engraved in the tissues of the body and can be stabilized through the bloodline." Genetics. Usually such creatures are also the main producers of potions and medicines on the market. The most typical example is unicorns..."

"Spiritual type means that this kind of biological organization does not have any magical structure and is no different from ordinary creatures. But their spiritual power can help them mobilize the magic of nature to cast spells like wizards, but generally speaking, they can only release fixed Several magics, the most typical examples being centaurs and merfolk... and house elves being a special case."

"Speaking of this, someone once tried to include goblins in this category, which resulted in quite a dispute..."

"The mutated category is the most special. It means that most of the body of this creature is an ordinary animal, but there is a special organ in their body that can be used to release magic. In the last century, this category has been considered unacceptable. Belonging to an independent classification, but a branch under the bloodline category, until Newt Scamander's theory was put forward..."

"This type of creature is the most common in nature, and is often mistaken for ordinary animals by inexperienced people, such as most species of owls, swallow-tailed dogs, and squirrels."

"Now let me show you the characteristics of these three magical animals... Let's start with the thorns first."

As he said that, Professor Kettleburn created another table, grabbed two thorns with his wooden prosthetic hand and put them on it, letting them lie down quietly: "Here is a thorn and a thorn. An ordinary hedgehog. Generally speaking, the only way to distinguish them apart from being pricked directly is to observe the reaction through feeding, but you see..."

He grabbed a hedgehog with one hand and took out his wand with the other hand. The tip of his wand suddenly glowed with a lavender light. Under the ray of light, the thorns on the hedgehog immediately reflected wonderful and complex colors, making the students dizzy.

"Do you see those colors? They represent the magical structure of this thorn."

"Through professional analysis, we can roughly judge the magic of this magical creature directly through these colors. Of course, this is only a rough judgment. If you want to know more about it, you still need to take samples and analyze it."

Professor Kettleburn looked at the ordinary hedgehog again, and sure enough it did not reflect the colorful light like the hedgehog.

"So Professor, when are we going to learn this spell?"

One student asked happily.

"This spell is quite difficult, sir. It is usually taught in the advanced classes of seventh grade. However, in fourth grade, you will start to learn to interpret the meaning of those spectra to determine the magic on a magical animal. ability……"

"Professor, I have another question."

This time it was Avada who raised her hand and asked: "What would happen if this magic was used to illuminate those incorporeal or invisible creatures, such as invisible beasts, Thestrals and Boggarts?"

"Invisible beasts cannot be illuminated when they are invisible. This is one of the reasons why their invisibility principle has always been a mystery."

Professor Kettleburn thought for a while and then explained: "Incorporeal creatures such as Boggarts need another magic to assist in research, and the spectrum they present will be much more complicated. This will be the time when you are in your fourth grade. Difficulties to face. As for Yeqi..."

"What's wrong with Yeqi?" Everyone looked at him curiously, not understanding why he suddenly paused.

"The situation of Yeqi is the most special."

He sighed: "Those who have not witnessed death and cannot see the Thestral are also unable to see the spectrum emitted. And those who can see the Thestral can see the spectrum, but it is a mess that cannot be analyzed. ... There is no explanation for this situation so far, not even a reliable guess."

"Okay, these are still too far for you now, let us focus on the current courses first..."

Soon, the third grade students’ first lesson on the Care of Magical Creatures came to an end. Kettleburn is indeed an old professor who has been teaching for more than 60 years. He has rich teaching experience and knows how to spread knowledge in the most vivid way - after all, who would refuse a cute and safe magical animal? ?

After Kettleburn left with a bang, the students returned to the castle with admiration and prepared to go to the next class. Avada, on the other hand, did not follow the flow of people back, but went in another direction alone - Hagrid's hut.

"Hagrid? Hagrid? Are you there?"

He knocked on the door and squatted down to scratch Yaya's itch. After a while, the door was opened, revealing Hagrid's tall figure: "Yo, Ken?"

"Did you just take Professor Kettleburn's class? How was it? Was his class great?"

"really."

Avada nodded and said: "But Hagrid, I am looking for you this time to inquire about something - have you heard of Slytherin's Chamber of Secrets?"

"How do you know this?"

Hagrid's eyes widened in surprise, and then a trace of sadness flashed in his eyes: "Of course I know about the Chamber of Secrets... Not only that, I was even expelled from Hogwarts because of the so-called Chamber of Secrets."

"What?!"

Avada's surprise was not fake - the Chamber of Secrets had obviously disappeared, and Myrtle didn't die from the basilisk. Why was Hagrid expelled for the Chamber of Secrets?

"Can you tell me more about it?"

Avada asked anxiously: "Oh, I'm sorry, it reminds you of bad things... but it's very important to me, so please tell me the relevant things!"

"Is it important? Why do you want to know the secret room so much?"

Hagrid scratched his head in confusion, but still did not ask this student who could even plot against Voldemort: "Originally this was just a legend, saying that Salazar Slytherin was very opposed to Hogwarts recruiting Muggles. The wizard eventually parted ways with the other three people who founded Hogwarts due to different ideas. When he left, he left a secret room in Hogwarts and a monster in it, which he would expel for him. , eliminate all Muggle-born students..."

"Originally, this was just a legend, but it wasn't until the years when I was in school..."

There was a trace of fear in his eyes, and he swallowed before continuing: "I heard that the secret room was opened at that time, and a student died because of it. Then, everyone said that I was the one who released the secret room. Monster…you’re just kidding, how could Aragog possibly hurt someone!”

"I was expelled from Hogwarts for this. Fortunately, Professor Dumbledore was willing to trust me and saved me from being imprisoned in Azkaban. I heard that people turned the school upside down later, but they didn't find it at all. The so-called secret room...that legend has become nonsense again."

"That's it." He sighed heavily.

"I see, thank you, Hagrid...Would you like some cookies? I made them myself."

…

After returning to the castle, Avada couldn't help but go to the abandoned bathroom and took another look - there was still nothing unusual.

'what happened? Why? ? ’

'If the Chamber of Secrets doesn't exist, why hasn't Hagrid's history changed at all? What exactly killed Myrtle? ’

'And if the Chamber of Secrets exists, where is it now? ’

‘What are you doing in the Horcrux Diary again? ? ’
