The Magical Principles of Natural Philosophy at Hogwarts

"So, this is what I want?"

Erwin looked at the translucent oily liquid in the test tube in his hand. It could not be seen from the appearance that it was made from a mixture of extracts of several highly toxic medicinal materials.

"You can call it - Tears of Abel. Many vampires will give each other a little drink when developing new ethnic groups, so that the transformation can be completed more conveniently. I have reduced the effect of the original version to make it more in line with your requirements.

I have asked your assistant Esmeralda to record the specific mixing process." Melanie said, keeping smiling.

She was forced to complete this job, and she didn't even have time to rest. This little brat had no sympathy for her, but considering the reality, Countess Melanie Dracula decided to endure it.

.

Erwin nodded slightly, expressing his affirmation.

For a newly made medicine, it is natural to determine its specific efficacy through experiments. Erwin clapped his hands, and an automatic magic cart drove in, with two cages on top, each cage containing

A grumpy little blue guy.

"Are these... Lockhart's elves?" Melanie asked curiously.

Gilderoy Lockhart tried to use a group of Cornwall elves as teaching aids in his second Defense Against the Dark Arts class this semester, but unfortunately it turned into a farce that he couldn't handle at all, and even had to

It was only with the help of the students that all these little guys, who were more than ten inches tall, were captured and returned to the cage.

"I'm going to use them to test medicine." Erwin said concisely.

Cornwall elves seem to be distant relatives of house elves. They have almost no value in themselves and can hardly cause harm beyond the level of mischief. After they were all captured, Hagrid was responsible for raising them, and the gamekeepers raised many animals.

, and don’t care about the extra batch of little guys.

But after all, they are annoying, not cute, and they are not beasts in nature. They cannot please Hagrid. Therefore, after Erwin said that he would deal with these troublesome creatures on his behalf, the gamekeeper did not ask any questions.

As for Lockhart himself, not to mention that he himself was completely controlled by Erwin, in fact he was eager to get rid of these Cornish elves who could not be returned.

In the process of drug development, it is essential to conduct animal experiments to determine its effect. Compared with the experimental rats, the effect of the Cornwall Elf should be better, after all, it can be regarded as a humanoid creature.

Two Cornwall elves were jumping up and down in the cage, baring their teeth and claws. Erwin casually cast two stun spells to calm them down temporarily.

The actual effect of Abel's Tears provided by Melanie is to weaken the drinker's immune system to a certain extent, making it more susceptible to the effects of other medicines. In order to make this effect easier to observe, Erwin prepared some in advance.

Purple quartz solvent, the most striking feature after taking this solvent is that the body will quickly turn purple.

Two Cornish elves served as a control group. One drank Abel's Tears first and then drank the amethyst solvent, while the other drank the amethyst solvent directly.

Five minutes later, it was obvious that the one who drank Abel's Tears turned dark purple, and then...burped directly.

It's not unexpected, after all, amethyst solution is somewhat toxic.

Abel's Tears is effective. Although the specific dosage requires many experiments to be determined, it is indeed effective.

This is only the first step. The next problem that needs to be solved is how to make a little bit of Erwin's blood improve his bloodline. This may require protracted attempts and research.

There is no need to rush.

"Hey, hey, hey, settle my reward first, as agreed." Melanie waved her hand in front of Erwin.

Yes, it was indeed said before that a simple death threat would not make her help wholeheartedly. If Erwin wanted her to do something, he would have to give a little of his own blood.

Erwin touched his fingertips with the tip of the wand, and under the action of the most basic cutting spell, a trace of blood seeped out. Erwin took three drops of blood, and then controlled them to float in front of Melanie.

Melanie opened her lips, rolled her pink tongue flexibly, and swallowed all three drops of blood.

Erwin was observing her, and he could feel that her physical condition had indeed improved through the magic shackles that he had become more and more able to control.

At present, it seems that she is only using his blood as a recovery medicine.

Melanie licked her lips, as if she was still a little unsatisfied. She suddenly came over and took Erwin's injured finger into her mouth before he could react.

The soft and moist feeling coming from his fingertips made Erwin's brain inevitably freeze for a moment. After all, his body was just that of an adolescent boy.

At this time, Melanie began to suck, and at the same time looked at Erwin with a full look.

Erwin reacted quickly, his face changed slightly, he took out his finger without hesitation, looked at the crystalline threads on it, and pointed the wand at his finger without the slightest thought.

"Clear water like a spring!"

Water gushes out from the tip of the staff. Erwin washes his fingers repeatedly, then presses them, and then summons Esmeralda, asking her to quickly send over the powerful antidote in stock, and then wash out all the bitter antidote in one breath.

Drink dry.

It was as if he had been bitten by some poisonous creature.

Melanie was stunned, her chest heaving, "You...you...what do you think of me?"

Even with the restraint of the vampire countess, she couldn't help it! "What do you think?" Erwin said expressionlessly.

After basically reading through those two books, in his opinion, the so-called blood magic can essentially be understood as controlling one's own cells, because blood is liquid and is the main carrier of magic. It is the easiest to control and the easiest to display power.

Although becoming a vampire can master blood magic, the price is to lose the opportunity to master other types of high-end magic. Therefore, their fighting methods are relatively simple. Even if they can live for hundreds or thousands of years in indirect dormancy, they will be difficult to be defeated by the top ones.

The wizard looked at him squarely.

So Erwin wasn't really worried about what Melanie would use his blood for. She was in her prime, and at most she could only use this blood to locate and track him.

But being licked is much more serious than giving someone a few drops of blood.

Saliva, like blood, is a body fluid, and it contains at least oral epidermal cells. If these cells can also be precisely controlled by Melanie, they may form parasites if they enter the blood from Erwin's wound.

Erwin now controls Melanie's life and death. If this woman finds an opportunity to control each other, it will not be a wonderful thing.

It must be guarded against.

Melanie calmed down. She was actually quite aggrieved. She could only tell herself that the guy in front of her was not a normal boy, or even a normal human being. He could not be taken down with a little trickery. She wanted to get him.

Trust requires enough patience...

And pay enough.

As for now, keep smiling, keep smiling.

"You are not allowed to have physical contact with me without my permission, and I will punish you next time." Erwin said.

There was a fire burning inside Melanie, and he used the word punishment as if she were a kitten or puppy.

It was getting late, Erwin took Melanie out of the Flamel cabin, and then put away the self-folding cube.

"Don't you think it's inappropriate to come to the Forbidden Forest all the time?" Melanie said casually: "It feels very inconvenient."

"Indeed," Erwin nodded,

Frequently entering and leaving the Forbidden Forest, no matter how careful you are, you will be noticed. Last time it was Malfoy who came to cause trouble, what if it is Snape next time?

He is not arrogant enough to think that he can defeat a professor and modify his memory.

He had no choice before, but now he knew that there was a wide, open and absolutely secret space underground under Hogwarts.

Secret room.

It is very suitable to be used as a secret base or stronghold. Many of Erwin's research can be conducted there instead of frequently opening and closing the Flamel House. This is also one of the benefits after defeating the Basilisk.

Parseltongue is required to enter and exit the Chamber of Secrets, but since Riddle's diary is in his hand, this is naturally not a problem. After realizing that the person he was talking to was "Harry Potter", Tom seemed to be enthusiastic

Just like grandpa.

In the past two days, Erwin described in Harry's tone how he was bullied and hated by Malfoy's classmates, and then he learned several curses from Riddle that were completely in the category of dark magic.

Tom very much wanted "Harry Potter" to trust him wholeheartedly.

Returning to Gryffindor Tower, Erwin handed Hermione a bottle of prepared lacewing decoction, which was the main ingredient for preparing Polyjuice Potion.

"It's only been three days, how did you do it?" Hermione was a little unbelievable.

"I bought a very powerful crucible." Erwin said lightly.

Normally it takes three weeks to brew, but the device in the potion room of Flamel's hut can shorten this time ten times.

Although the threat from the Chamber of Secrets has actually been resolved, Erwin does not object to Harry and Hermione's efforts to refine the Polyjuice Potion, and is even willing to provide some help.

Because these three children actually gathered the materials directly.

Polyjuice Potion can make the drinker change into the appearance of another person, and it is completely indistinguishable by conventional means, so its finished product and main raw material African tree snake skin are strictly controlled and not for sale. But Harry was able to get African tree snake skin,

The source is still Professor Snape's potion collection, and it certainly did not have his consent.

He actually had the guts to steal Snape's collection, and the Potions professor had no intention of pursuing it. Erwin estimated that Professor Snape might have been instructed by Dumbledore to do something about Harry.

Turn a blind eye and close an eye.

This may be the privilege of the Boy-Who-Lived, a privilege that even Erwin does not have. Anyway, he would definitely not dare to collect it from Professor Snape.

This made Erwin feel that it was necessary to get closer to Harry. After all, he had to fight with Riddle in the name of this young man. If he had more contact with him, he could learn to be more like him, and Erwin felt that it was necessary to get closer to Harry.

It is possible that I may need to "borrow" Harry's privilege in the future.
