The Magical Principles of Natural Philosophy at Hogwarts

Erwin stood outside the bathroom door, staring at the girl inside.

Ginny held a wand in one hand and a black-covered diary-like object in the other. It was obvious that she was not trying to solve a physical problem.

She was also unaware of the existence of the two people not far away.

She first pointed her wand at the water tank of a toilet behind her. As a faint light flashed, the water tank made a slight noise and shook.

"There is a ghost named Myrtle living there." Melanie whispered to Erwin: "She is binding the ghost inside and not letting her come out."

Ginny looked at the sink in the center of the bathroom, and suddenly she made a weird hissing sound.

This immediately activated some kind of mechanism, and the pool began to split and spread out, revealing a huge water pipe.

Erwin's expression moved slightly. Sure enough, this school hides many secrets.

However, Ginny just opened this strange passage. She suddenly looked very flustered, as if she had made a mistake. After a while of gasping, she made that hissing sound again, and the pool slowly returned to its original state.

Then the little girl ran away as fast as a thief.

After the silence was restored, Erwin and Melanie appeared, "How many times has this happened?" Erwin asked.

"The second time." Melanie said: "She looked like this very scared last time."

How could this little girl escape Melanie's eyes when she wanted to do something?

Erwin nodded slightly, walked forward, approached the pool, and imitated Ginny's hissing sound from memory. It felt like it was breathing, and animals in nature generally use this sound to express threats.

As expected, nothing happened.

"What on earth is this sound? It sounds like it is made by a snake-like animal." Erwin looked at Melanie, "Do you know what Ginny is talking about?"

"have no idea."

"You don't know?" Erwin looked surprised.

"Why should I know?" Melanie asked.

"I thought age and knowledge were directly proportional." Erwin shrugged.

"Are you trying to call me old in a different way?" Melanie's eyes narrowed slightly.

"You can understand it that way. I checked the information and it is said that powerful vampires can live for thousands of years." Erwin had a slightly evil-looking smile on his face.

Even female vampires seem to mind talking about their age.

Erwin suddenly felt a sense of fun unique to boys in teasing girls.

"The Vampires do have a longer lifespan than humans," Melanie said coldly: "But this does not mean that we have any special advantages in resisting aging. In the final analysis, the Vampires essentially just use blood magic and

They are just special humans who can obtain magic power directly from their blood.”

"Interesting." Erwin nodded and motioned for her to continue. It was a rare experience to listen to a vampire talk about vampires.

However, Melanie stopped at this time, and then suddenly laughed, "Are you very interested in vampires?"

"Kinda." Erwin admitted.

"Then you should know that knowledge also comes with a price."

"What do you want?" Erwin said simply.

"Lighten the shackles that restrict me...Okay, I know this is impossible, then I want a drop of your blood?"

Erwin was not surprised that this female vampire was trying to distract him, but...

"Only one drop?"

He only hesitated for a second, "Deal."

Using a wand with a basic cutting spell on it, she lightly scratched her fingertips, and a drop of blood seeped out. Melanie caught it with a white finger, and the blood droplets condensed between her and never dispersed.

With the moonlight coming from the window, Melanie carefully looked at the blood beads with a faint silver line, then stretched out her soft and flexible pink tongue and licked it gently.

Erwin stared at her, not seeing any clues from her expression.

Melanie, who tasted Erwin's blood, continued to tell:

"Compared to normal human wizards, our biggest advantage is that we can precisely control our bodies. By minimizing the activity of our body's organs, we will fall into a state similar to death. In this state, we can

Cheating time, this is the 'sleep' of our vampire family."

"In other words, most of your so-called long life span is spent sleeping?" Erwin found it very interesting.

"That's right."

"Since sleeping is almost equivalent to suspended animation, how do you ensure safety during this period?"

"This is the meaning of a clan. Blood clans with the same surname look after each other. Most members are in deep sleep. A few wake up to maintain normal affairs while protecting the safety of other members. This is usually done every ten to thirty years.

Rotation.”

Erwin remained calm on the surface, but secretly he understood that the vampire clan was an organization with much closer internal links than he imagined.

"Thank you for sharing this knowledge." Erwin clapped his hands, "Then you..."

"I just woke up from my deep sleep two years ago." Melanie looked very calm, "The last time I woke up was about a hundred years ago."

"So how many times have you been in deep sleep in total?" Erwin asked casually.

"twice."

Erwin smiled evilly again, "That means you are almost three hundred years old."

"Yes." Melanie kept smiling, her slender hands secretly clenched into fists.

"Extension of life by constant dormancy is not a true immortality, but it seems pretty good." Erwin thought for a moment, "I suddenly want to be a vampire."

"Are you sure?" Melanie's expression moved slightly, "I can help you, but after becoming a vampire, you can basically only use the magic of the vampire..."

"Of course not." Erwin said without hesitation.

After grafting the bloodline, his lifespan will definitely be improved, and if he really wants to live forever, turning into a primitive dragon and finding a ravine will be a more reliable way.

The conversation turned back to the hissing sound he had just heard. "It sounded like a snake," Erwin said.

"That should be the sound of snakes, snake language." Melanie said.

"Theoretically, snakes' intelligence should not be enough for them to create language."

"But people can." After saying this, the female vampire smiled and said nothing.

Erwin was stunned. He suddenly thought that Master Flamel once said that he had performed blood grafting for many ancient magic families.

It is obviously very reasonable for a wizard to graft himself with the blood of some kind of magical giant snake, establish a family, and then create a language that imitates the snake's hissing.

And Slytherin's symbol animal is the snake.

Is it possible that the ancestors of the Weasley family were grafted with snake blood? This statement is a bit unreliable. After all, their whole family graduated from Gryffindor, but the Sorting Hat should not make decisions purely based on blood...

Erwin subjectively does not want to explore other people's secrets. The secrets of the Weasley family essentially have nothing to do with him, but the problem is that now it involves Hogwarts itself.

Where does that giant water pipe lead to? What's in it?

"Pay more attention to Ginny and see what she does next," Erwin said to Melanie.

Let’s wait and see what happens for now.

The next morning, Erwin went to the library, searched based on keywords, and quickly found the corresponding entry.

Parseltongue.

The ability to talk directly to snakes is possessed by Salazar Slytherin and his descendants.

Are the Weasleys direct descendants of Slytherin? Then Erwin would believe that Hagrid has the blood of Rowena Ravenclaw.

During lunch, he went to the auditorium and sat down directly next to Melanie. Others were already accustomed to it and assumed that they were a couple.

Although he seems a bit young, it is not uncommon for boys and girls of this age to fall in love.

Melanie looked full after eating only one-eighth of the pie, so she took out a piece of parchment and started writing and drawing.

"What are you doing?" Erwin asked while chewing a slice of ham.

"Designing a fourth squiggle for Gilderoy Lockhart."

"You haven't lost interest in him yet?" Erwin shook his head, feeling a little pity for the parallel import professor.

"There's always something to do." Melanie said calmly.

"You might as well form a support club for him." Erwin said casually.

Melanie stopped what she was doing, raised her head and looked at him, "Support club?"

"Organize readers who are obsessed with him, and then help him publicize and increase his reputation."

"That's a good idea." Melanie's eyes lit up.

After what they had done, the relationship between the two seemed to get closer. After a few casual conversations, Erwin quickly finished his food and left the auditorium.

Bypassing the troublesome Whomping Willow, passing the Quidditch pitch, and entering the Forbidden Forest, Erwin walked deeper into the area with ease. Just like the previous few days, he would walk to the open space on the other side, and then unfold Flamel

hut to conduct his research.

But he couldn't do that today, because suddenly there was... a car in the open space?

Erwin thought he was dazzled, but a car actually appeared in the forest next to a magic school?

The car was from the style of thirty or forty years ago. It was undoubtedly a classic car. It was in a very bad condition. All the glass products were broken, and the original green color of the bumpy car body could barely be seen.

With Erwin's wand in hand, he slowly approached. When he was still more than ten meters away, the dilapidated old car suddenly started, and there was a real roar of the engine.

This is really a car.

Erwin looked at the driver's seat, but there was no one there.

The suddenly started car rushed towards Erwin, not very fast. Just when he was about to react, the classic car suddenly turned an astonishing curve and rushed into the forest, gradually disappearing.

Erwin shook his head slightly. He would not be surprised at all if he saw any strange things in the future.
