The Magical Principles of Natural Philosophy at Hogwarts

Facing the administrator's reminder, Erwin didn't take it seriously. "How many carriages are there in total?"

"Twenty Festival."

Erwin silently made a mental calculation, and found that the space utilization rate of this old-fashioned carriage was not high. Assuming that each carriage seats forty people, the number of students in Hogwarts would not exceed 800 at most.

"Thank you." He nodded to the administrator, pulled the suitcase and walked towards the car behind him. Hermione couldn't keep up with him, "Where are you going?" she asked breathlessly.

"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 Lived came to buy a wand, which meant that he also enrolled this year and was on this platform or on the train.

Harry Potter.

Erwin has already thought clearly that even if he is really in the world depicted in a children's literature, getting close to the protagonist should have a better chance of coming into contact with the truth.

Although the most likely consequence of uncovering the truth is to be swallowed by the truth, Erwin is fearless. That is better than dying in a dream.

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

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

Then it became quiet.

Taking Hermione with him, Erwin was about to enter a carriage when he was suddenly stopped by a boy, "You don't come from a wizarding family, right?" 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, "You must not enter this compartment, it is full of Slytherins.

People only welcome children from wizarding families, and I was just kicked out by them."

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

Young wizards from Muggle families should unite!

The three of them didn't go far when they met another red-haired senior student with a red-gold badge on his chest. "You haven't found a suitable position yet?" he said understandingly, "Follow me.

There is a carriage specially reserved for freshmen.”

He took them to an empty cubicle, where a boy with a round face was already sitting. When he saw them, he hurriedly moved out of the way.

"I am Percy Weasley, the prefect." The senior student finally said, "If you have any questions, you can come to me directly."

, "Hey, Percy!" A pair of twins, both with red hair, suddenly appeared and patted Percy's shoulders heavily. "Guess who Ron met?" One of them screamed in a pretentious manner, and the other immediately screamed.

Shout out the answer, "Harry Potter!"

"I've seen him!" Percy said, looking like he was suppressing his anger.

Erwin looked at these three people. From their hair color and facial contours, he could tell that they were a family. He remembered the surname Weasley very clearly. Considering the pitiful population of British wizarding society, it should not be a problem.

How many Weasleys are there?

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

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

"I had some dealings with him during the summer vacation. I got into some trouble, and Mr. Weasley helped me deal with it."

"Dad's position is the director of the Office for the Prohibition of Misuse of Muggle Items," Percy frowned slightly, "Generally speaking, he doesn't care about this kind of thing, unless the department is really short of manpower..."

"I remembered." One of the twins said suddenly.

"I remembered it too." Another one sang along, "Dad said during the summer vacation that a little wizard stuffed a fat Muggle's butt into an iron frame ten feet above the ground." They approached Erwin.

, eyes flashing with excitement, "Did you do it?"

Everyone else in the cubicle looked at Erwin with expressions of surprise, including Hermione, who didn't know that Erwin had ever done such a thing.

"He asked for it." Erwin said calmly.

"It's so cool," the twins said in admiration. "It is said that the iron frame was stuck so tightly that it took twenty Grease Curses to help him remove it."

Percy looked a little unhappy. "The Ministry of Magic has banned Hogwarts students from using magic during the holidays," he told Erwin. "You can't do this kind of thing anymore, otherwise you will be in trouble."

The corner of Erwin's mouth twitched, "Only after entering Hogwarts will you be prohibited from using magic outside the school? Does this mean that this ban is not valid for children under the age of eleven?"

Percy was stunned for a moment, "That should be the case, but it's normal for a little wizard to be unable to control his magic power..."

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

So he was actually taking advantage of a loophole in the law by practicing magic unscrupulously at home a few days ago?

But logically speaking, the Ministry of Magic should not have the ability to directly monitor every spell released by every wizard, otherwise Dipu and Marduk would not be able to act wantonly in the UK...

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

Dean Thomas was an acquaintance and easily struck up a conversation with the round-faced boy. The boy's name was Neville Longbottom. He was born in a wizarding family and was quite shy.

The train moves and the front of the train makes a huge noise. To be honest, this is not magic at all.

Near half past twelve, a smiling woman opened the carriage door and brought a trolley filled with food. “Would you like to buy some food for the car?”

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

The snacks provided on 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 the user to have

Some harmless effects, such as spitting out a flame with no temperature, 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 a bit difficult to accept it.

.

"There are even candies made to look like cockroaches," Neville said.

"Aren't people who eat that kind of food afraid of a real cockroach getting mixed into the candy?" Erwin expressed his confusion.

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

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

Neville nodded desperately.

Several people searched this compartment but found nothing.

"I'll ask you somewhere else," Hermione volunteered.

She came back a quarter of an hour later, gesturing that she had found nothing.

"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 find someone who is truly capable for help."

Miss Nutria understands.

When Percy put Lyford, the toad found with the locking spell, into Neville's hands, the boy was so excited that he almost cried.

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

The prefects began to notify the new students to change into robes. This standard school uniform is quite simple and is pure black.

The car stopped, and people crowded to get out of the car. A figure much taller than the average person shouted not far away: "Freshmen! Freshmen, come to me."

"That's a giant?" Neville looked a little scared.

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

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

Neville felt 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 nothing wrong with it, a very unpretentious mode of transportation, as unmagical as taking a train.

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

"Welcome, children." Professor McGonagall said softly, seemingly looking specifically in Erwin's direction.

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 entire school's teachers and students.

, I suggest you tidy up while waiting."

Many children were nervous and worried about the sorting ceremony. At this time, several ghosts suddenly broke in, causing a small panic. Erwin was very interested in them. This was the first time he had seen them with his own eyes.

to this legendary existence.

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

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 an old wizard's hat placed 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 magic item is not an uncommon phenomenon in the wizarding world.

"Whoever my name is, go over and put the hat on your head." Professor McGonagall said, "Hannah Abbott!"

A rosy-faced blonde girl stumbled out and put on a hat, the brim of which just covered her eyes. After a moment, "Hufflepuff!" the hat shouted loudly.

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

What's worse is that, 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 wearing glasses attracted everyone's attention. He put on his hat and after more than ten seconds, he said, "Gryffindor!"

Hat yelled.

Erwin sighed, it seemed he had no choice.

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

…”

"Stop!" Erwin almost shouted.

"Don't want to go to Ravenclaw?" Hat seemed confused.

"I choose Gryffindor."

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

"Classification is a process that requires great caution. More factors must be considered. It is extremely inappropriate to make a hasty decision." Erwin calmed down.

"You see, this is the way Ravenclaw thinks."

"The screening criteria for Ravenclaw is logical thinking? So what qualities do Gryffindors need?"

"courage."

Erwin thought for a moment and continued to express his thoughts after a moment, "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 ultimately drives you. You will not burst out your courage unconditionally, and it must be limited by your rational judgment."

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

But of course he would not give in. "On what basis did you make such a judgment? Can you pry into my memory?" he asked sharply.

"I'm just a broken hat, I don't have that powerful ability."

"Then you just make decisions based on the students' thoughts at the moment they wear you? Then you label the students with a label that will affect their lives? Forcibly divide them into different groups? Isn't this system ridiculous?"

The hat was silent.

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

"Gryffindor!" Hat suddenly shouted, and the loud voice echoed in the auditorium.
