The Magical Principles of Natural Philosophy at Hogwarts

The following Friday, Erwin showed Flitwick the cleansing spell he had become so adept at.

"Fantastic." Flitwick applauded.

"It's time to give me extra points, Professor." Erwin was not polite.

"Okay, the cleansing spell is also a fourth grade spell, it deserves encouragement, five points from Gryffindor."

"not enough."

"Then how much do you want?" Flitwick was surprised.

"Fifteen points."

"That won't work, you can't add more than [-] points for a single non-major event."

"What about this? The water glass is flying!" Erwin yelled, and the water glass on Flitwick's table was in his hand immediately.

In fact, he didn't need to say a spell at all, or even use a wand, but it was still necessary to pretend.

"Flying Curse, that's great." Flitwick smacked his lips, "Okay, okay, add fifteen points to Gryffindor."

Satisfied, Erwin returned to the common room, "because Neville's lost points have been made up." He said to Hermione, "Now you have no reason to condemn me. And if Neville continues to In Potions, Snape will keep finding excuses to deduct points from him, so overall we earn."

Miss Nutria gave him a supercilious look.

After rebuilding his self-confidence, Neville's performance was extremely unexpected. He originally performed mediocre in Transfiguration and Charms, but suddenly he became one of the best students, and his learning speed for new spells can be said to be only Second to Hermione.

This is not surprising, a key element in casting magic is will and conviction, and this is all the more pronounced at the lower levels of spells used.And Neville was by no means a child without talent.

But it seems unbelievable to others, even Professor McGonagall couldn't help but think that maybe it's really a good thing for Neville not to take Snape's class,

Erwin spends half a day every week helping Neville practice potion preparation. The simple camp on the outskirts of the camp is not limited to this role. Erwin can also practice some spells that are not very convenient to disclose, such as illusion. body curse.

Due to the high consumption of mana, Erwin had to drink a cup of tea mixed with the Fountain of Power every 15 minutes of practice, so his stomach was full of water almost every day, and he even had to vomit, which was very uncomfortable.

After overcoming many difficulties, Erwin finally successfully used the illusion spell for the first time after 217 attempts, and after 325 practices, he was able to achieve stable success in chanting the spell.The reason for such an accurate count is that every practice is equivalent to burning one Galleon.

Quite a feat indeed, Erwin must have broken the record for a 12-year-old to learn the Auror spell.

But it is not enough to master the illusion spell. It must be combined with the silent spell that can eliminate the sound, the concealment spell that can hide the smell, and the anti-detection spell that can block the general detection methods.The pure optical invisibility flaw is too obvious, and four spells must be used at the same time to achieve the real stealth effect.

Fortunately, the mana consumption of the latter three spells is not as outrageous as the Disillusionment Curse, but the difficulty is not low, and it takes a lot of time for the lover to practice, and he can't do other things recently.

So October is almost over, and Hogwarts is about to welcome Halloween.Erwin finds it strange, because Halloween is actually a festival with a strong religious atmosphere, and the history of magic has said that most Muggle religions are actually just toys for wizards.

Maybe wizards celebrate Halloween just because they want a reason to have fun and celebrate.

On the eve of Halloween, the layout of the auditorium is very atmospheric, with hundreds of jack-o-lanterns floating in mid-air, and densely packed bats.The dinner and subsequent Halloween celebrations would last until about nine o'clock, and Erwin wasn't interested, so he ate two steaks and went back to Gryffindor Tower.

Sitting in an armchair in the common room, grabbing a book, Erwin hadn't read a few pages when he heard a noise, the door of the common room opened, and almost all the Gryffindor students rushed in , Many lower grade students showed panic.

The lounge became very crowded all of a sudden, Erwin found Neville with great difficulty, "What happened?"

"Professor Quirrell says there's a troll in the dungeon," said Neville.

"Trolls?" Erwin recalled the description in "Fantastic Beasts and Where to Find Them". The danger of this creature is mainly reflected in its tyrannical physical strength and skin with high magic resistance, but its IQ is extremely low.Thanks to the dynamic pictures in the book, although Erwin has never seen it with his own eyes, he has a relatively complete understanding of the troll.

"A giant monster can't even cross the lake outside the castle, how could it enter the castle silently." Erwin pondered for a while, "Could it be that Professor Quirrell wanted to use this giant monster as a teaching material, but accidentally lost it?" control over it?"

That's pretty outrageous, but at least it makes sense.

Neville thought for a while, and then looked at Erwin with admiration, "I think it should be the situation you mentioned. By the way, when I came back, I saw Harry and Ron walking in the opposite direction, and they didn't come back .”

"Do these two people want to challenge the troll?" Elvin wondered.

As expected of the Boy Who Lived, he was brave enough, a born Gryffindor.

"Probably not." Neville seemed to have thought of something suddenly, "Parvati!" He asked like a brown-skinned girl who looked Indian, "Is Hermione back yet?"

"No, I haven't seen her since the afternoon,"

Neville gasped, "Harry and Ron should have gone to find Hermione," he said firmly.

"What's the specific situation?" Erwin frowned.

"There was a lot of conflict between Hermione and Ron in Charms class today." Neville kept the story as short as possible, "Hermione cried and then disappeared all afternoon, she may not know about the troll .”

"Is that so..." Erwin thought for a while, and then said decisively, "Then I have to go out too."

He had promised Professor Stewart that he would take care of Hermione.

If the goal is not to kill, the danger of creatures like trolls is actually very limited.And Erwin has basically mastered the four stealth curses now, so if he is careful, he should be able to avoid being discovered by anyone.

Taking everything into consideration, Erwin felt that it was okay to take risks.

After hearing that Erwin wanted to go out, Neville's first thought was not violating school rules or anything, "I'll go with you." He said without hesitation.

Erwin smiled, "It's too easy for two people to be discovered. I can go by myself. You should tell the prefect Percy about the situation and let him find a way to notify the professors."

Neville didn't insist anymore, and nodded vigorously.

Walking out of the common room, Erwin avoided the sight of the fat lady, took out his wand and chanted four spells in a row, entering the true sense of stealth.

On the way from Gryffindor Tower to the main castle building, there were almost no people, even ghosts could not be seen. Erwin walked down the stairs and suddenly met Professor McGonagall with a serious face.

He stopped immediately, and Professor McGonagall hurried past him without any intention of stopping.

Well, even the professors wouldn't be able to spot Erwin in stealth if they didn't use the advanced detection spell.

Continuing to go down, when he turned the corridor, he suddenly smelled a foul stench faintly, and then he could hear the girl screaming.

It must be Hermione!

Erwin quickened his pace. He saw broken walls and doors. This was originally a women's toilet, and he could see the huge body of the troll inside, but there was a tall old man standing outside the door, holding a magic wand.

It's Dumbledore!

Erwin's footsteps stopped abruptly. Since the principal of Hogwarts is here, there is no need to worry about Hermione's safety. Dumbledore is recognized as the most powerful wizard in Britain.

But what is he doing?

Erwin approached slowly and found that the troll was fighting with two boys, it was Ron and Harry.A normal Hogwarts first year student wouldn't learn any spells that could hurt a troll, and it's a joke to fight a troll with the physical strength of two human children, that monster is a head taller than Hagrid, The arm like a giant log can crush two boys into a pulp with just a sweep.

If it wasn't for Dumbledore being here.

The old headmaster pointed his wand at the giant monster, and the huge monster seemed to have suddenly suffered from severe arthritis, and its movements became extremely slow. He roared angrily, but he couldn't help the two boys.

The young and naive Harry and Ron didn't feel anything unusual at all. They worked hard and focused on fighting the troll, including knocking on the water pipe to attract its attention and poking their noses with their wands.They didn't even notice Dumbledore's presence.At this moment, Ron finally realized that his wand could perform more than a stick. He waved his wand and said the spell he tried for the first time this morning, "Wingadim Leviosa!"

The thick wooden stick in the troll's hand suddenly flew up, and then hit its head precisely. This monster with rough skin and thick flesh was knocked out like this. It is hard to imagine that the height difference of less than two meters could make the wooden stick Has such amazing strength.

The troll shook twice and fell heavily to the ground.

Harry and Ron gasped wildly, "Okay, Ron," Harry said, "What a powerful Levitating Charm."

Ron smiled stupidly. He didn't let the feathers fly this morning, but now he can defeat a giant monster with the levitation spell-he doesn't think there is any problem with it.

Several professors finally appeared, and it was impossible for them not to notice the movement.Erwin felt that it was a bit outrageous, the movements of the professors were too slow, trolls are not invisible or fast creatures, and there is not much space inside Hogwarts castle, shouldn't it be the first Did you find out right away?

Unless... Erwin looked at Dumbledore subconsciously.

The headmaster still had a kind smile on his face, "These children will be handed over to you. Take care of their precious courage, let alone my help." He winked at Professor McGonagall, obviously not Going to show up in person.When he left, he glanced at Erwin intentionally or unintentionally, which made the latter's heart skip a beat.

was found.Erwin isn't taking any chances.

It is of course reasonable that Britain's strongest wizard can see through his stealth, but Erwin is not sure whether his identity has been known by the headmaster, after all, the disguise has not been revealed.

Perhaps Dumbledore would have thought it was a curious senior?

With some apprehension, Erwin backed away quietly and left here, and Professor McGonagall's angry voice could be faintly heard behind him.

In the end, none of the three children were substantially punished.

On the second day of Charms class, Ron, who had become friends with Hermione, waved his wand vigorously at the feather in front of him, "Wingardim Leviosa! Wingardim Leviosa!" He repeated over and over again. Shouting everywhere, and finally even got angry.

However, the feather didn't move at all, and it was as heavy as a thousand weights.

"How could this be?" Ron was puzzled, and he groaned and put his head on the table, "I obviously used it yesterday..."
