The Magical Principles of Natural Philosophy at Hogwarts

"Can a bedroom be free?" Hermione was taken aback. "Did all the girls there happen to go home?"

"Of course not, but there are not many people staying in school. I can let them go to another dormitory to squeeze together."

"Really?" Ron was a little unbelievable, "Those girls are willing to listen to you? Is what you say more effective than the prefect?"

"They are all my friends, so they are naturally willing to help me." Melanie smiled charmingly.

Erwin was also a little surprised. Melanie did a better job than him in terms of uniting classmates.But it's not surprising if you think about it carefully, he spends most of his time tinkering with his own research and doesn't deal with other people.But this female vampire has a lot of free time. She doesn't have much to do in Hogwarts. She basically can't learn much about wizards and magic. Apart from reading some idle books, she also deals with other little girls.

Although vampires have been dormant for most of their lives, Melanie has at least several decades of experience and social experience. According to her, she is one of the spokesmen of vampires in conventional society in Romania. It can be said that it is easy for the little girl to fall in love with her.

Give her a little more time, and she might become the de facto president of the female student council.

Hermione wanted to ask Melanie why she wanted to help her, but swallowed the words as soon as they came to her lips.

I almost forgot that she and Erwin are in a relationship, and Erwin and himself... can be regarded as relatives.

Hermione had an inexplicable emotion in her heart.

"Since the dormitory problem has been solved, we'd better return to the Gryffindor Tower now." Erwin said: "Staying here is very risky, and it is easy to be seen by others."

Everyone agreed.

"Put on the hat of the robe, Hermione, well, you have to bend down again, otherwise you will still be able to see the abnormality of your face." Harry suggested.

"And a tail," said Ron, with an uncontrollable smile on his face.

Hermione gave him an annoyed look, and curled up her cat's tail, which hung outside her robes.

Suddenly there is an extra part that has never been there before. This feeling... is really strange...

Erwin frowned for a moment, then took off his robe and handed it over. "Wear mine," he said curtly.

This wasn't some bloody romance plot, the fact was that he was now an adult, and only his robe could completely cover Hermione.

Hermione didn't say much, took Erwin's robe and put it on herself.

She didn't have to worry about whether Erwin was cold or not, because she saw the dragon leather vest on his body, which was made by him himself last year.

Harry, Ron, and Hermione all have one, which was a Christmas present from Erwin last year.

Hermione was tightly wrapped in a large robe, "Then let's go," Erwin said.

He was the first to come out of the bathroom, followed by Harry and Ron, followed by Hermione, who had just reached the door when Melanie came up.

"Can you feel Erwin's residual heat?" she asked quietly, then smirked past Hermione, not giving her time to react.

Hermione's body froze, she secretly clenched her fists and took several deep breaths.

It wasn't a long way from the women's bathroom on the second floor of the castle to the Gryffindor tower, but Hermione was very nervous, she was afraid of meeting someone.So she has been hiding behind the three boys intentionally or unintentionally.

Fortunately, it was the Christmas holiday and it was night, so I didn't meet anyone.

But for fear of something, a bright lantern shone unceremoniously on their faces. Behind the lantern was an ugly hooked nose, and behind the nose was a gloomy face.

Administrator Filch, who hasn't been nice to any of the students since what happened to his cat.

谷屎

"What are you doing here, Harry Potter?" Filch seemed to dislike Harry all the time, and often pointed at him, "And that faceless student, what's the matter with you?"

Harry muttered inwardly, thinking about how to deal with Filch, but Melanie spoke first, "Merry Christmas, Mr. Filch."

This sudden greeting made Filch a little stunned, and his expression couldn't help but soften a little.

Erwin gestured to Harry and Ron to keep silent.

"My friends and I are on our way back to the dormitory." Melanie continued in a brisk tone: "It's very late, we won't come out to trouble you after we get back to the dormitory. Wrapped clothes It's Miss Hermione Granger, she accidentally got herself wet in the bathroom, and we're all juniors, you know, and we don't know the Drying Charms yet."

Harry and Ron nodded.

Filch looked at them suspiciously for a while, then looked at Melanie, and his tone was surprisingly kind, "Then go back quickly, you are a good boy, girl, don't talk to these shameless bad boys from now on. Play together."

He said, glaring at Harry and Ron sternly, then turned and paced away.

After seeing Filch's back, Ron couldn't help but ask, "How did you do it? Why is Filch so friendly to you?"

"Because I look cuter." Melanie said with a smile.

All the way back to the Gryffindor tower without any danger, others waited in the common room first, Melanie entered the girls' dormitory, and with the excuse of holding a Christmas party to enhance their relationship, she effortlessly made the first-year girls spontaneously Concentrate in another bedroom.

This creates a separate room.

Hermione was placed there temporarily, and there were no classes during the Christmas holidays. For her, it was just a few days without going out.

In principle, boys should not enter the girls' dormitory, but Erwin can also openly say that he has no dirty thoughts.

What's more, for him who has mastered the four stealth curses, he can easily prevent any students from noticing his whereabouts.

Now it was time to make a compound potion containing Hermione's own substance. She had become like this, and it was obviously inappropriate to use her hair. Erwin pricked her finger and took a little blood.

The blood of a wizard can basically be said to be the safest form of identification.

Adding that drop of Hermione's blood to the bottle of Polyjuice Potion Erwin had received that morning turned golden brown in no time.

"It looks pretty good, even a little bit of mango aroma." Ron commented fairly. "In comparison, the bottle of Crabbe essence solution I drank before... It's like the vomit of a troll."

Enter Hermione's dormitory room, let her drink her own Polyjuice Potion, and after a few minutes, it is obvious that the hair on Hermione's face has shortened a lot.

The next step is to use the Transformation Blocking Spell, the effect of this spell can be known just by looking at the name, preventing the transformation effect that is happening or is about to happen.The effect of the compound decoction is divided into two stages, transformation and return to the original form. Now the use of the transformation blocking spell is to cancel the return to the original form, because only the transformation effect is needed to make Hermione gradually change back to herself.

The solution provided by Riddle is effective. As for whether the Transformation Blocking Curse can be used in the battle between wizards, this problem can be understood in this way. The scalpel used for medical treatment also has the ability to hurt people, but it will be more powerful than normal weapons on the battlefield. Is it more efficient?

Of course not, but it does not rule out the possibility of occasionally winning by surprise under certain circumstances.

The first stage of recovery treatment was over, and the effect was not bad, and Hermione's mood calmed down a bit.

"Go to sleep first, don't think too much." Erwin said.

He returned to the common room and broke the good news to Ron and Hermione.

The two boys were relieved.

They were also tired, chatted with Erwin, and went upstairs to their dormitory together. Today's experience was really unusual for them.
