The Magical Principles of Natural Philosophy at Hogwarts

Ordinary wizards believe in spells as truth, but skilled wizards feel that fixed spells often become limitations, and they let magic serve them in the most appropriate form.

Erwin's strategy was successful. His "generosity" made all the lower-grade Muggle-born students get to know him and have a good impression of him.

The few students who didn't come to the meeting came to Erwin secretly and embarrassedly a few days later, hoping to get an alarm ring.

Their needs were of course met immediately.

Ron has been a little busy these two days. He no longer thinks about the five hundred galleons. The most obvious advantage of this young man is his good attitude. Even if he has any negative emotions, they will not last long. What he is worried about now is His sister, Ginny Weasley, although she was obviously born into a pure-blood family, she was even more uneasy than those little Muggle-born wizards.

Ron thought it was because she liked cats, and she was frightened by the tragic situation of Filch's cat, Mrs. Norris.

Erwin heard him enlightening his sister, "Maybe you don't know Mrs. Norris very well. To be honest, we would be happier without it. Similar things usually don't happen in schools, and the perpetrator should be there soon." Get caught and kicked out of school.”

As the youngest boy in the family, Ron didn't have many opportunities to show his brotherly demeanor. While he tried his best to comfort his sister, he didn't feel there was anything unusual about Ginny's increasingly pale face.

Erwin was not far from them, and he naturally heard everything Ron said, and also noticed Ginny's appearance.

This seems to be the reaction a little girl should have after accidentally getting into a big trouble. But the problem is that Mrs. Norris can understand it if she just petrifies her, but leaving those words on the wall is hard to say that she did it impulsively. If she had a relatively clear belief about the matter, why would she be so panicked?

Could it be said that there is someone behind the scenes?

Erwin looked at Melanie, who shook her head slightly at him.

The two of them avoided the Weasley brothers and sisters. "The little girl hasn't done anything unusual in the past two days," Melanie whispered, "but there is something strange. She writes in her diary too frequently."

"How weird is that?"

"Based on time, she writes two thousand words in her diary almost every day. It's hard to imagine what she actually recorded."

Erwin thought thoughtfully. Children of this age rarely have the ability to write for a long time, let alone write so much every day. And if he remembered correctly, Ginny also took it when she went to the women's bathroom that night. Holding something like a diary.

It is self-evident where something is abnormal.

"You can test her," he said to Melanie.

It is not appropriate to report to professors just when you find an abnormality, and it is easy to alert others.

"Testing it? Then don't worry." Melanie smiled slightly, with light flashing in her eyes.

Putting the school affairs aside, Erwin continued his research on the magic text. The progress of the Ring of Rebuke and the magic text Uzi has almost reached one-third. It will take a long time to be completely completed. Optimistically, it will be completed in Completed before the end of the school year.

Although Erwin memorized a lot of magic codes under the pressure of Nico Flamel, it is not that simple to master them. This cannot be solved by blood talent. He has to go through many detours before he can understand. How to avoid it.

But having said that, it is also very enjoyable to build your own equipment with your own hands.

Taking the time to read through the two books about blood magic, Erwin discovered an interesting fact, that is, the similarity between real vampires and vampires in Muggle literature is quite high.

Is it possible that art really comes from reality? Even the author of the earliest vampire literature was himself a vampire?

Based on the content in the book, combined with the fragmentary information Melanie said before, Erwin generally has a relatively clear understanding of blood magic.

He knew what role Melanie could play.

He immediately finished what he was doing, got up and rushed back to Hogwarts Castle. In the corridor outside the main building auditorium, Erwin saw Filch roaring at the fifth-year Ravenclaw students.

"You! I said you are not allowed to use magic in the corridor, but you just don't listen!"

After Mrs. Norris's accident, Filch became even more neurotic and extremely malicious to all students.

Part of the reason may be that most of the underclassmen know that he is a squib.

"But we don't want to use magic." The two Ravenclaw students were helpless.

"Then why did you take out the wand?" Filch's tawny eyes flashed fiercely, "Don't try to fool me!"

No matter how hard the two students tried to explain that they were just discussing the connection between the wand's material and its owner's personality, Filch still stubbornly wrote down their names in the notebook.

Erwin calmly took two steps back and cast the Disillusionment Curse on himself at the same time. He did not want to be affected. Although Filch was an idiot, he did have some power in his hands.

His attitude was like revenge. In this magic school, every little wizard was causing pain to him who had no magic talent every moment. This was the source of hatred.

People born in a magical society without magical abilities are like poultry in a flock of birds, much more miserable than ordinary people who know nothing about the magical world.

Even so, Filch is still difficult to sympathize with, and he is not essentially a good person.

Returning to the Gryffindor common room, Erwin was somewhat surprised to find that a small conflict was breaking out here, between the Weasley brothers and Melanie.

The crying Ginny was protected by Ron, who was holding his neck. She hugged her diary tightly, and the dark cover attracted part of Erwin's attention.

"You can't bully my sister." Ron's eyes were red with anger.

Harry on the side was a little at a loss. There was a girl opposite him. It seemed inappropriate to stand on his friend's side and help him?

Melanie looked very calm, "No one bullied her, it's just that we all shared our secrets, but when it was her turn, she regretted it. I think this is inappropriate, right?"

Erwin understood that Melanie should have organized a tea party for Gryffindor first-year girls. The girls shared their little secrets with each other to enhance their relationship. When it was Ginny's turn, it was natural for him to look at her.

diary, after all, she writes a lot of words in it mysteriously every day.

Then Ginny refused and had a strong emotional reaction.

It's really a good test method.

Melanie's calm attitude, coupled with the lethality of her appearance, caused Ron's momentum to weaken rapidly. He looked back at Ginny with some confusion. The little girl buried her head and cried even harder, still holding on.

Hold her diary.

Ron's momentum returned again, "No one can force my sister." He said every word.

"No one forced her." Melanie smiled faintly, "But Ginny Weasley, since you don't want to blend in with everyone, don't blame everyone for treating you as an outsider."

The Gryffindor girls beside her all looked at Ginny with a hint of indifference.

With just a few tricks, Melanie excluded Ginny from the Gryffindor girls' circle of friends.

"You are going too far." Hermione couldn't help but said, Miss Nutria has always had a sense of justice.

Facing Hermione, Melanie raised her chin slightly, "Who are you?"

Hermione almost lost her breath.

The younger girls in Gryffindor seemed to be following Melanie now. They introduced Hermione to Melanie chatteringly, as if they really met on the first day, and emphasized that Hermione was not popular.

, not good-looking but also troubled.

Hermione took a deep breath, then another.

"That's enough!" Ron couldn't bear it any longer. He roared so loudly that many girls were startled. He pulled Ginny and Hermione to the other side of the lounge.

"It's okay," he comforted Ginny, "Don't worry about what those girls think, we don't care about being their friends. Look at Hermione, she doesn't get along well with any girls, so she still has me and Harry as friends.

Her friend?"

Hermione's face was very stiff, and she already had the urge to throw the book in her hand at Ron's head. This guy really didn't like to pick up any of the pots.

Over there, Erwin coughed slightly to indicate his presence.

Melanie knew that he wanted her to go out with him, so she smiled a little apologetically and shyly at the other girls, and the girls gave them meaningful looks.

Melanie has almost made everyone understand their "couple" relationship.

Erwin took Melanie to the top of the tower. The cold wind of late autumn came out, which made people sober.

"How does that drop of my blood taste?" Erwin asked looking at the female vampire.

He has not forgotten this.

"It's a wonderful feeling..." Melanie's eyes were a little confused, "But you don't have to worry about what I will do with your blood. I have almost no ability to use blood magic now, not to mention that my life is in your hands.

In hand."

Erwin was noncommittal, "I have a few questions for you. Vampires have difficulty reproducing themselves, so the most important way to increase the population is...'first embrace'?"

This proper noun is quite difficult to pronounce.

"yes."

"So, are there any talent requirements for being possessed for the first time?" Erwin then asked.

"Theoretically there is no such thing,"

Erwin nodded slightly. Vampires are also a kind of blood, and this blood can be copied and transmitted with low loss. This is essentially a biotechnology, a technology that can be copied and improved.

He is now a genuine Origin Wizard, and where does the greatest value of the Origin Wizard lie? It lies in the word "Origin".

The original bloodline needs to be spread, and forming a family and passing it on through reproduction is actually very slow and inefficient.

According to the theory of modern economic breeding, generally speaking, male individuals should be matched with ten or dozens of times as many female individuals. Compared with being a seeder, Erwin felt that there should be a more efficient method.

This is the point of keeping this female vampire.
