The Magical Principles of Natural Philosophy at Hogwarts

After hearing this discriminatory name, Hermione's eyes widened with anger.

Filch was roaring. He firmly believed that the three Harrys had murdered his cat. Faced with his incoherent accusations and loud cries, Harry's defense was as weak as withered grass in a storm.

Erwin looked at Malfoy, "Excuse me, what did you just call me?" He looked very confused.

Brother Lao was immediately amused, "Isn't this the first time you've heard someone call you this? It's really sad. I'd say you should go back and live a good life with your Muggle family..."

"What on earth did you say?" Erwin still looked incomprehensible.

"I called you a Mudblood, you idiot!" Malfoy became a little angry.

Erwin sighed, showing an extremely helpless look, "You also heard it, professors, this has caused great harm to my soul."

Malfoy was stunned. He slowly turned his head and saw Dumbledore, Professor McGonagall, Professor Snape... almost all the faculty and staff were here.

Right behind him.

His face immediately turned pale. Why was he unaware of their arrival?

"Five points from Slytherin." Professor McGonagall's face was cold, "Please apologize to them immediately, Mr. Malfoy."

Classmate La Ge looked at Snape with a grimace, but his dean didn't seem to be willing to stand by him when it didn't involve Harry Potter, so he could only treat Hermione like a fly.

Say sorry.

Miss Nutria raised her head proudly.

Erwin faced Malfoy with a bright smile. He had already seen that this little bastard was a purely lustful and stubborn guy. He was usually arrogant and domineering, but when he met someone with real power, he would give in faster than anyone else.

.

Maybe this is their family's usual style of doing things.

Dumbledore calmed the caretaker, and then checked the stiff cat. "It's not dead, Argus," he said to Filch.

"But why is it so stiff..."

"It's petrified."

There was a small noise around, and many students looked relieved. Death was really too heavy for these children, even if it was just a cat.

Erwin also observed from a distance, Mrs. Norris looked like a frozen corpse, which was not the result of an ordinary petrification spell.

Filch was still very excited, "It was Potter who did it. He is so lawless. You must punish him."

"I don't think Harry is capable enough to use such a powerful petrification spell... Let's talk about it somewhere else."

"My office is upstairs, you can go there." Gilderoy Lockhart was quite eager to express himself.

"Sorry, Gilderoy." Dumbledore nodded slightly, "Other students, you can go back to your dormitories." He said in a very calm and reliable tone.

The students automatically separated to let the professors pass. Before leaving, Snape stared sharply at Erwin's sleeve, as if he could see the wand hidden inside.

Erwin remained calm. He had just used a simple and clever silent spell to prevent Malfoy from noticing the arrival of the professors. The wand itself is a very small object, and some simple means can be used to create visual deception.

For example, holding the front half of the wand like he did just now can hide it in the sleeve. Although it has a considerable impact on casting spells, it is sufficiently concealed.

Of course, this cannot be hidden from experienced veterans.

On the way back to the dormitory, Erwin leaned next to Melanie and asked, "Where is Ginny?"

Melanie pointed out the disturbed red-haired girl to Erwin.

"Did she write those words?"

"Maybe." Melanie looked a little indifferent.

"Pay more attention to her and tell me if there is anything unusual," Erwin said.

This little girl is indeed a little strange, but at this time it is not clear what she is going to do, so you might as well wait and see what happens.

The next morning, Erwin found Colin Creevey in the Gryffindor common room and returned the camera that already had color photography capabilities to him.

However, Colin did not look happy, but looked worried, "The secret room has been opened, and we Muggle-born people will be in danger..."

"Where do you start talking about this?" Erwin felt a little strange.

"My roommates have been telling me this last night." Colin swallowed. "It is said that the founder of the school, Salazar Slytherin, left a secret room. Once it is opened by his heir, terrifying things will happen.

Things come out of it and eliminate the people in this school who are not worthy of learning magic."

"This sounds quite similar, but you don't need to take this rumor to heart." Erwin didn't care too much.

Not to mention that those words were written by Ginny, how could the professors at Hogwarts allow students to receive death threats in the school.

But one day later, Erwin found that the atmosphere of panic was spreading. "Hogwarts: A School History" in the library was borrowed out, just because it mentioned the Legend of the Chamber of Secrets; Hermione confronted Binns in the History of Magic class.

The professor asked about the Chamber of Secrets. Although the ghost professor kept emphasizing that this was just a rumor without any factual basis, it did not calm the students' emotions; Justin Finch-Fletchley, who originally played well with Harry Potter, now sees him

He just hid because he was from a Muggle family and Potter was suspected of opening the Chamber of Secrets.

It is normal for children to be immature and suspicious. Erwin began to think about what he could do in this atmosphere.

"Do you know any other Muggle classmates in the same grade as you?" he asked after finding Colin.

"Some of them are familiar to me, but not all of them are known to me," Colin replied.

"Help me convey the news to them. I hope they will come to the second backup classroom of the Charms class on Friday afternoon, and I will provide them with some help." Erwin patted his shoulder.

It was not a difficult task, so Colin agreed.

Erwin personally informed the second grade students. On Friday afternoon, a total of twenty first and second grade Muggle students came to the spare classroom No. 2 of the Charms class.

"All Gryffindors are here, eight Hufflepuffs are here, and one Ravenclaw is here... It seems I still have some appeal." Erwin was quite satisfied with this.

According to Hogwarts teaching regulations, there are no classes on Friday afternoons, so Erwin can use this classroom as he wishes.

Erwin stood in the lecturer's position and looked at these young students, "I believe everyone has already felt it. In this magical world, we are a faintly isolated group. We do not have a huge magical family, nor do we have a large magic family."

As for our relatives who know magic, the only one we can rely on is ourselves. In this case, we Muggle-born wizards should unite and help each other."

His speech did not receive much response. Colin was the only one who applauded.

What should we do next? Announce the formation of a Muggle student club? That would be too direct, and Erwin would naturally not be so impatient.

He clapped his hands, and Melanie came up with a box. The background Dumbledore arranged for her was naturally impossible to come from a magical family, so she was "regarded" as a Muggle student.

"I know everyone is worried about the secret room, so I have prepared some gadgets for you." He took out a very simple metal ring from the box, "This is a simple magic item, it can provide certain

The defensive effect helps you resist a curse, and if you break it directly, a very harsh alarm will sound, like this."

As Erwin demonstrated, harsh noises echoed in the classroom, and the students had to cover their ears, but their eyes shone with excitement.

"I think when you are really attacked, this ring should be able to help. The alarm will let the professors know that you are in danger and come to help." Erwin opened the bag, "Each of you can

Take one, that's why I came to you."

"Can we...really take it?" an apple-faced Hufflepuff girl asked cautiously.

In the minds of these little wizards, even the simplest magic items are quite valuable.

"Of course." Erwin nodded and put a ring directly into her hand.

A blush rose on the Hufflepuff girl's apple face, "Thank you, my name is Ashley Loreamon." She introduced herself in a low voice.

Erwin smiled kindly in return.

"Everyone can take one." Erwin called to the others.

A few young wizards were still hesitant, but under the pressure of the secret chamber rumors, they finally chose to accept it and took the ring from Erwin.

Hermione was the last one, "How much did you spend to buy these rings?" she asked worriedly.

The two were nominally related, and she was worried about Erwin spending money arbitrarily.

"These are all made by me." Erwin didn't hide it either.

The cost and technical content of these rings are very low. The so-called magic defense is to offset an ordinary stun spell. It is a one-time use. It is basically a thing to fool children. It only took Erwin half an hour to create all these rings.

.

But from another perspective, these simple gadgets can play a big role in making Muggle-born wizards feel at ease.

In Hermione's eyes, these rings are not "simple gadgets", and her expression is a little complicated, "So this is what you learned in the special training some time ago?"

"That's right." Erwin nodded, indeed he studied magic literature.

Hermione took a deep breath. Last school year, she got excellent scores in all subjects and was the undisputed number one in the grade. She thought she should be no worse than Erwin, but she didn't expect that she was still left behind by him.

Professor Dumbledore only asked Erwin to undergo "special training", obviously because he only thought he had talent in this area.

This shocked Hermione to a certain extent.

She turned her eyes to Melanie again, looking at her exquisite and delicate facial features, Miss Nutria received a second blow.

She suddenly remembered an old book she had dug out in the library, "How to Use Magic to Shape Beauty."

Maybe...she should read the contents?
