The Magical Principles of Natural Philosophy at Hogwarts

Facing the administrator's reminder, Erwin didn't care. "How many carriages are there?"

"Twenty verses."

Erwin made a mental calculation silently. The space utilization rate of this old-fashioned carriage is not high. Based on the calculation of [-] people in each carriage, the number of students in Hogwarts will not exceed [-] at most.

"Thank you." He nodded to the administrator, pulled the suitcase and walked towards the back compartment. Hermione couldn't keep up with him. "Where are you going?" She asked out of breath.

"Find a good seat." Erwin looked around.

He was actually looking for a boy, the only clear name in that memory.

In the wand shop, Ollivander told Professor McGonagall that the boy who survived came to buy a wand, which meant that he was also enrolled this year, on this platform or on the train.

Harry Potter.

Erwin has already figured it out that even if he is really in the world depicted in a children's literature, getting closer to the protagonist should have a better chance of getting in touch with the truth.

Although the most likely consequence of uncovering the truth is to be swallowed by the truth, Erwin is fearless, and that is better than being drunk and dreaming of death.

But he quickly gave up temporarily, because he didn't know Potter at all, he only knew that the other party had a scar on his forehead, and it was too difficult to find someone based on this feature alone.

Saby the great horned owl attracted a lot of attention. This guy would quack and squawk when he saw other owls in the cage, as if he was going to fight in the air, until Erwin put his wand into the cage and knocked it on the head Just calm down.

With Hermione, Erwin was about to enter a carriage, but was suddenly stopped by a boy, "Should you not come from a wizard family?" He had a kind smile on his face.

"Yes, what's the matter?"

The boy looked relieved, "My name is Dean Thomas, and my parents don't know magic." He was a little nervous, "Don't go into this compartment, it's full of Slytherins People, only children from wizarding families are welcome, I was kicked out by them just now."

"Thanks for the reminder." Erwin nodded slightly, "Then let's find another seat together."

Young Muggleborn wizards should unite!

The three of them didn't go far, and met a red-haired senior student with a gold and red badge pinned to his chest, "Have you found a suitable place yet?" He said empathetically, "Come with me, There are special compartments reserved for freshmen."

He led them to an empty cubicle, where a round-faced boy was already sitting, and when he saw them, he hurriedly moved out of his seat.

"I'm Prefect Percy Weasley." The senior student finally said, "If you have any questions, you can come to me directly."

"Hey, Percy!" A pair of red-haired twins suddenly appeared and slapped Percy on the shoulder heavily, "Who do you think Ron met?" One of them screamed pretendingly, and the other immediately Call out the answer, "Harry Potter!"

"I've seen him!" said Percy, looking suppressed in anger.

Erwin looked at the three of them, judging from the hair color and facial contours that they were a family, and he remembered the surname Weasley very clearly. Considering the pitiful population of the British wizarding society, it should not be so How many Weasleys are there.

So he said, "Excuse me, is Mr. Arthur Weasley your elder?"

Percy was a little surprised, "You know our father?"

"During the summer vacation, I got into some trouble, and Mr. Weasley helped to deal with it."

"Dad's job is to be the director of the Office of the Prohibition of Misuse of Muggle Substances," Percy frowned slightly, "generally, he doesn't care about this kind of thing, unless the ministry is really short of manpower..."

"I remember," one of the twins said suddenly.

"I remember that too," the other chorused, "Papa said during the summer that a little wizard put a fat Muggle's ass in a metal frame ten feet above the ground." They moved up to Erwin , with excitement shining in his eyes, "Did you do it?"

Everyone else in the cubicle looked at Erwin with surprise on their faces, including Hermione, who didn't know Erwin had done such a thing before.

"That's what he asked for." Erwin said lightly.

"It's so cool," the twins looked admiringly, "It is said that the iron frame was stuck so tightly that it took twenty greasy spells to remove it for him."

Percy looked a little unhappy. "The Ministry of Magic forbids Hogwarts students to use magic during the holidays," he told Erwin. "You can't do this kind of thing anymore, or you'll be in trouble."

The corner of Erwin's mouth twitched, "Only after entering Hogwarts will you be banned from using magic outside the school? That means this ban is not valid for children under the age of 11?"

Percy froze for a moment, "It should be like this, but it's normal for little wizards to be unable to control their magic power..."

"That shows that this regulation actually has a lot of loopholes."

So the unscrupulous practice of magic at home a few days ago was actually taking advantage of the loopholes of the law?

But logically speaking, the Ministry of Magic should not be able to directly monitor every spell cast by every wizard, otherwise Dipper and Marduk would not be able to act recklessly in the UK...

The three Weasleys left, the twins, George and Fred, winking at Erwin as they went.

Dean Thomas was an acquaintance, and it was easy to strike up a conversation with the round-faced boy, Neville Longbottom, who was born in a wizarding family and was quite shy.

The train was moving, the engine was making a huge noise, and it wasn't magic at all to be honest.

When it was close to 12:30, a smiling woman pushed the door of the carriage, carrying a small trolley full of food, "Do you want to buy some food in the car?"

In the spirit of spontaneous research, "Please give me a copy of each, thank you," Erwin said.

The snacks provided by the train are basically sweets. Erwin feels that they can be roughly divided into three types according to their characteristics. The simplest one is to use magic means to improve the taste and taste of the food itself. The second type is to allow users to have Some harmless effects, such as spraying out a mouthful of low-temperature flames, and the last one is to imitate food into some kind of animal. Although he knew that the jumping frog in front of him was made of chocolate, Erwin still found it difficult to accept. .

"There's even candy in the shape of cockroaches," said Neville.

"Isn't someone who eats that kind of thing afraid of a real cockroach getting mixed into the sugar pile?" Erwin expressed his puzzlement.

After lunch time, Neville suddenly yelled, "My toad is gone."

Still a child with amnesia, "Did you remember to bring the car?" Erwin asked.

Neville nodded desperately.

Several people searched in this compartment, but found nothing.

"I'll help you find other places to ask." Hermione volunteered.

She returned a quarter of an hour later, gesticulating that nothing had been found.

"Don't forget that we are now in a society dominated by magic," Erwin reminded her.

"What do you mean?" Hermione was a little confused.

"What I mean is...you might as well ask someone who is really capable to help you."

Miss Nutria understood.

When Percy put the toad Rifle, which he had found with the Locking Charm, into Neville's hands, the boy was on the verge of tears.

It was getting dark, which meant that the destination was approaching, and Erwin estimated that they should be in the north of Scotland now.

The prefects began to tell the freshmen to change into robes. This standard school uniform was quite plain and pure black.

The car stopped and the crowd got out of the car.A figure much taller than ordinary people shouted not far away: "First-year freshman! First-year freshman, come to me."

"Is that a giant?" Neville looked a little scared.

"Probably not," said Hermione. "Fantastic Beasts and Where to Find Them says giants are at least five meters tall."

The unusually tall man introduced himself as Hagrid, the Hogwarts Gamekeeper.

Only then did Neville feel relieved.

They finally saw Hogwarts Castle, but there was a huge lake in front of the castle, and the way to cross the lake was...by boat.

There seems to be no problem, a very unpretentious mode of transportation, as unmagical as taking a train.

At the bottom of the castle, Hagrid knocked on the door, and the door opened in response, and a witch wearing a tall hat walked out, it was Professor McGonagall.

"Welcome, children." Professor McGonagall said softly, as if looking at Erwin on purpose.

They were first taken to a room, and Professor McGonagall explained to them the sorting ceremony they were facing.

"Gryffindor, Ravenclaw, Hufflepuff, Slytherin. Each house has its own glorious history and has produced outstanding wizards. In a few minutes, the sorting ceremony will be held in front of the whole school. , I suggest that you tidy up yourselves while you wait."

Many children fell into a tense mood and were worried about the sorting ceremony.At this time, several ghosts suddenly broke in, causing panic in a small area.Erwin is very interested in them, this is the first time he has seen this legendary existence with his own eyes.

He even reached out and touched it secretly, and then confirmed that the ghosts were not purely invisible, they were like a condensed fog.

interesting.

Professor McGonagall appeared again and led them into the brightly lit auditorium. Students from the four colleges sat around four long tables. In the center of the auditorium was a chair with a worn wizard hat on it.

After all the freshmen came in, the wizard hat on the chair suddenly made a sound and sang a strange song.

A self-aware magical item is not an uncommon phenomenon in the wizarding world.

"Whoever I call out, go and put the hat on," said Professor McGonagall. "Hannah Abbott!"

A rosy-cheeked blond girl stumbled out, put on her hat with the brim just over her eyes, and a moment later, "Hufflepuff!" the hat yelled.

The sorting process is quite simple, but the problem is that they have to come one by one. Erwin looked back, there are more than 80 freshmen in total, even if each of them takes 1 minute, the sorting ceremony will last for an hour and a half.

What's worse, as a temporary student, he is likely to be the last one.

Dean Thomas, Gryffindor.

Neville Longbottom, Gryffindor.

Hermione Granger, Gryffindor.

Harry Potter, when Professor McGonagall called out his name, this thin black-haired boy with glasses attracted everyone's attention. He put on his hat, and after ten seconds, "Gryffindor!" hat yelled.

Erwin sighed, it seemed he had no choice.

Sure enough, he was the last one. After waiting for two full hours, everyone felt a little tired.Erwin put on the sorting hat, and immediately a voice came from his ear, "Excellent way of thinking, you obviously belong to Lavin..."

"Stop!" Erwin almost shouted.

"Don't want to go to Ravenclaw?" The hat seemed puzzled.

"I choose Gryffindor."

"Well, you do have extraordinary courage, but believe me, Ravenclaw would be the best place for you."

"Sorting is a process that needs to be very cautious, and more elements must be considered. It is extremely inappropriate to make a hasty decision." Erwin calmed down.

"You see, this is the Ravenclaw way of thinking."

"Ravenclaw's screening condition is logical thinking? So what qualities does Gryffindor need?"

"courage."

Erwin thought for a while, and continued to convey his thoughts after a while, "I think I should be one of the few students who dare to debate with you."

"I don't deny your bravery, but the problem is that it is not this quality that drives you in the end. You will not explode your courage unconditionally, and you must be limited by rational judgment."

In short, it wasn't reckless enough, and Erwin had to admit the hat was right.

But of course he would not admit defeat, "What is the basis for you to make such a judgment? Can you spy on my memory?" He asked sharply.

"I'm just a broken hat, not that powerful."

"Then you just make decisions based on the students' thoughts at the moment they wear you? And then label the students with a life-changing label? Forcibly divide them into different groups? Isn't this system absurd?"

The hat was silent.

"I suddenly have doubts about your intelligence level. Magical creations should also be graded. How strong is your thinking ability? I just have a few questions, so I can roughly determine your intelligence level..."

"Gryffindor!" The hat suddenly called out, and the loud voice echoed in the auditorium.
