The Magical Principles of Natural Philosophy at Hogwarts

Erwin stood outside the bathroom door, watching the girl inside.

Ginny held a wand in one hand and a black journal-like thing in the other, obviously not trying to solve a physical problem.

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

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

"There lives a ghost named Myrtle." Melanie said softly to Erwin, "She's keeping that ghost inside so she won't come out."

Ginny was looking at the sink in the middle of the bathroom when suddenly she let out a weird hissing sound.

Immediately this activated some kind of mechanism, and the pool began to split and spread apart, revealing a huge water pipe.

Erwin's expression moved slightly. Sure enough, this school hides a lot of secrets.

However, Ginny just opened this strange passage, and she suddenly showed a very flustered expression, as if she had made a mistake. After a while of panting, she made that hissing sound again, and the pool slowly returned to its original state. Then the little girl ran away as quickly as a thief.

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

"The second time," Melanie said, "she looked very frightened the same way last time."

How could the little girl want to do something that could escape Melanie's eyes.

Erwin nodded slightly. He walked forward, approached the pool, and imitated Ginny's hissing sound according to his memory. It felt like breathing. Animals in nature usually use this sound to express threats.

Unsurprisingly, nothing happened.

"What the hell is that sound? It sounds like a snake." Erwin looked at Melanie. "Do you know what Ginny said?"

"do not know."

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

"Why should I know?" Melanie asked rhetorically.

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

"Are you trying to call me old?" Melanie narrowed her eyes slightly.

"You can understand it this way. I checked the information. It is said that powerful vampires can live for thousands of years." Erwin had a wicked smile on his face.

Even female vampires seem to mind talking about age.

Erwin suddenly felt a little boy's sense of fun playing tricks on girls.

"The vampires do have a longer lifespan than humans," Melanie said coldly, "but it doesn't mean that we have any special advantages in resisting aging. After all, the vampires are essentially just using blood magic and It's just a special human who can directly obtain magic power from blood."

"Interesting." Erwin nodded, beckoning her to continue, listening to a vampire talk about vampires is also a rare experience.

However, Melanie stopped at this moment, and then suddenly laughed, "Are you interested in blood race?"

"A little bit," Erwin admitted.

"Then you should know that knowledge also has a price."

"What do you want?" Erwin asked simply.

"Leave the shackles that restrict me a little... well, I know it's impossible, so I want a drop of your blood?"

Erwin wasn't surprised that the female vampire was distracting him, but...

"It only needs one drop?"

He only hesitated for a second, "Deal."

Gently swipe at the fingertip with the magic wand with the basic cutting spell, a drop of blood oozes out, Melanie oozes out a white finger to catch it, and the blood condenses between her and does not disperse.

With the help of the moonlight coming through the window, Melanie carefully looked at the blood drop with a faint silver line, then stretched out her soft and flexible pink tongue, and licked it lightly.

Erwin stared at her, not seeing anything from her expression.

Melanie, who tasted Erwin's blood, went on to tell:

"Compared to normal human wizards, our greatest advantage lies in our ability to precisely control our own bodies. By minimizing the activity of our body organs, we will fall into a state similar to death. In this state, we can Deceiving time, this is the 'slumber' of our blood race."

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

"Yes."

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

"This is the meaning of the clan. Blood clans with the same surname take care of each other. Most of the members are in a deep sleep. A small number of people wake up to maintain normal affairs while protecting the safety of other members. Generally, a round is carried out every ten to 30 years. for."

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

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

"I only woke up from a deep sleep two years ago." Melanie looked very calm, "The last time I woke up was about 100 years ago."

"So how many slumbers have you had in total?" Erwin asked casually.

"twice."

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

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

"Relying on continuous hibernation to prolong life, although it's not really immortal, seems pretty good." Erwin thought for a while, "I suddenly want to be a vampire too."

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

"Of course not." Erwin said without hesitation.

After being grafted with blood, his lifespan must have improved, and for him, if he really wanted to live forever, it would be a more reliable way to become a primitive dragon and find a ravine to drill.

Turning back to the hissing sound, "Sounds like a snake," Erwin said.

"That should be the cry of a snake, the language of a snake," Melanie said.

"In theory, snakes should not be intelligent enough to create language."

"But people can." After saying such a sentence, the female vampire smiled and said nothing.

Erwin was taken aback for a moment, and it suddenly occurred to him that Master Flamel once said that he had grafted blood for many ancient magic families.

It is obviously reasonable for a wizard to graft himself the blood of some kind of magical snake and start a family, and then imitate the snake's neighing to create a language.

And the symbolic animal of Slytherin is the snake.

Could it be that the ancestors of the Weasley family were grafted with the blood of snakes?This statement is a bit unreliable, after all, their whole family is a Gryffindor graduate, but the Sorting Hat should not make decisions purely by blood...

Erwin subjectively doesn't want to explore other people's secrets. The secrets of the Weasley family have nothing to do with him in essence, but the problem is that Hogwarts itself is now involved.

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

"Pay attention to Ginny and see what she will do next." Erwin said to Melanie.

Wait and see for the time being.

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

Parseltongue.

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

The Weasleys are direct descendants of Slytherins?If it is said that Hagrid has the blood of Rowena Ravenclaw, Erwin also believes it.

During lunch, he went to the auditorium and sat down directly next to Melanie. The others had already seen it and agreed that they were a couple.

Although the age seems to be relatively 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 a pie. She took out a piece of parchment and began to write and draw.

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

"Fourth curlicue signature for Gilderoy Lockhart."

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

"Always find something to do." Melanie said flatly.

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

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

"Organize those readers who are obsessed with him, and then help him to promote and increase his fame."

"Good idea." Melanie's eyes flashed.

After finishing the work, the relationship between the two seemed to be getting closer. After a few casual conversations, Erwin quickly settled his food and left the auditorium.

Bypassing the troublesome Whomping Willow, passing the Quidditch pitch, and entering the Forbidden Forest, Erwin walked into the depths with ease. Like the previous few days, he would walk to the open space on the other side, and then spread out LeMay Hut, to conduct his research.

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

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

The car was in the style of 40 to [-] years ago. It was undoubtedly a classic car, and it was in a very bad condition. All the glass products had been broken, and the original turquoise could barely be seen on the bumpy body.

With Elvin's wand in his hand, he approached slowly. 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 really is a car.

Erwin looked at the driver's seat, which was empty.

The suddenly launched car rushed towards Erwin, and the speed was not very fast. Just when he was about to respond, the classic car suddenly turned an amazing arc, rushed into the forest, and gradually went away.

Erwin shook his head slightly, and he wouldn't be surprised if he saw any strange things in the future.
