The Magical Principles of Natural Philosophy at Hogwarts

Never expect a group of children to maintain discipline without a teacher present, especially when these children are naturally divided into two completely opposite groups.

Erwin has a mature mind, so he thinks it is ridiculous for children to fight like houses. The so-called Academy Cup is essentially the same as a small red flower awarded to children, without any practicality.

It is also difficult for him to feel a sense of belonging to Gryffindor House, because he does not agree with the concept of courage first and joining this house does not give him any additional benefits.

So he just watched the Gryffindor kids and the Slytherin kids arguing.

Classmate Malfoy found the memory ball left by Neville on the grass, and planned to hide it in a hard-to-find place to play a trick on poor Longbottom. This greatly angered classmate Potter's righteous heart, and the two completely

Forgetting what Mrs. Huo Qi said before leaving, she flew into the sky on a broomstick to confront him.

After talking a few rubbish, Malfoy threw the memory ball directly. Potter accelerated his dive, straightened his broom less than two feet from the ground, caught the memory ball, and then fell gently on the ground.

On the grass, unscathed.

Erwin shook his head. It was indeed very Gryffindor behavior to make such a dangerous attempt when he was not sure of his abilities.

Except for Hermione, all the children in the Lions Academy looked at Potter with a kind of heroic look. Professor McGonagall, who came after hearing the sound, was frightened. She severely reprimanded everyone and then took Harry away.

The next time I saw Potter was at lunch, he was telling Ron in a low voice that he had been chosen as Gryffindor's Seeker by Professor McGonagall.

"Seeker?" Erwin, who was not far away, naturally joined their conversation and raised his apple juice cup to Potter. "A position in a team is destined to be called a hero. Congratulations,

Harry."

As the only sport accepted by wizards all over the world, Quidditch has a set of rules that are completely inconsistent with competitive standards. A single goal is only ten points, but once the seeker catches the Golden Snitch, he can get one hundred and fifty.

Ten points and the game ends immediately, which results in the Seeker being even more important than the other players combined.

It's like a certain king's stupid son wanted to play Quidditch. No one dared to let him lose, so he told him that he didn't need to worry about anything in the game, just grab the little golden thing and you would win. So from then on

There is an additional Seeker position.

Harry and Ron seemed startled by Erwin, "Did you...hear us?"

"It's not intentional, but you guys are talking too loudly." Erwin shrugged.

Hermione almost choked on her pumpkin juice. "When school started, didn't it say that first-year students were not allowed to participate in Quidditch?" She opened her eyes wide.

"Last year Gryffindor lost many times to Slytherin, and Professor McGonagall said we must have a Seeker." Potter said with a little vanity, "And the Headmaster also agreed."

He suddenly thought of something and lowered his voice, "Don't talk about it everywhere. It needs to be kept secret before the first competition."

Hermione looked a little unhappy. She was an admirer of order and rules, but classmate Potter actually received a reward for breaking the rules, and the reward itself was also against the rules.

Erwin sneered in his heart, fair and square, haha.

It's time for classmate Malfoy to appear. It seems that his main function at Hogwarts is to promote the internal unity of Gryffindor. This kid didn't look directly at Erwin and Hermione, which fully demonstrated his innocence.

Pride of Blood. First he mocked Ron, and then challenged Harry Potter to a duel in the prize room at midnight.

Porter, who was full of enthusiasm, agreed without hesitation, without even thinking about the possibility of being let go.

"Are you crazy?" Hermione couldn't help it. She asked immediately after Malfoy left: "Walking around without sleeping at night is not allowed. Once caught, you will make Gryffindor

How many points will be deducted? This is too selfish..."

"Okay, Miss Nosy. This matter has nothing to do with you." Ron couldn't help but said, he and Harry stuffed the food on the plate into their mouths, and hurried to class.

Erwin glanced sideways at Hermione and found that she had a very bad look on her face.

After all, Miss Nutria's appearance is a bit ugly. If she were cuter, the two boys might not have this attitude.

That night, while the Gryffindors were going upstairs to go to bed, Erwin stayed in the common room reading his tomes. As he read these books, he would randomly experiment with the things mentioned in them.

A simple and interesting spell that will disturb other people's rest if it is in the dormitory.

Someone stayed here with him, "Aren't you going to sleep yet?" Erwin asked.

"I want to finish my thesis on the History of Magic." Hermione said without looking up.

At eleven o'clock, Harry and Ron sneaked down from the dormitory at the top of the tower. Hermione stopped them immediately. She had been waiting for a long time.

It was another quarrel between chicken and duck. Hermione didn't have any capital to convince the two boys. "I'll go with you." Finally, she was heartbroken. "If you are caught, I will tell the professors that I am

How to persuade you, this may cause Griffin to deduct some points."

She looked at Erwin for help, but the latter was completely focused on the book and just waved to them, "I wish you good luck."

Hermione could only helplessly follow the two boys out of the lounge.

Erwin continued to read, but not long after, he heard the rustling noise again. When he looked up, he saw two more guys sneaking out of the dormitory, with the iconic red hair and the same face.

"Hey, Erwin." The Weasley twins came to him and said, "We are going to the kitchen to find something to eat. Do you need to bring you a midnight snack?"

Erwin knew what they meant, "No need to bribe me, I haven't seen you two tonight." He said,

Fred and George gave him understanding looks.

This was certainly not the first time for these two people to sneak out at night. "Aren't you afraid of being discovered?" Erwin asked casually.

"Usually only Filch patrols around at night, and even if other professors suddenly patrol the castle on a whim, we have ways to avoid them."

Erwin didn't ask what the method was. One rule of maintaining a friendly relationship with others is to mind their own business. If the other party doesn't take the initiative to tell you, don't ask further.

"But those portraits should be able to see you." Erwin suddenly thought of something.

"The portraits are all mentally retarded." Fred said nonchalantly: "They can't remember the students' faces. It would be great if they could remember the passwords like the Fat Lady."

After the twins left, Erwin closed the book. He suddenly felt that the Hogwarts system seemed to encourage violation of school rules.

The portrait that acts as a gate guard will not prevent students from going out at night. The "Instruction Office" only has a man who does not seem to have magic and a cat. Only these two creatures patrol the huge castle at night, and even if they are caught, they will only be detained.

points, the cost of violation is pitifully low.

I feel sorry for Principal Dumbledore if I don't do anything.

But of course not tonight.

More than an hour later, classmate Porter and his group came back, and they all looked shocked.

As expected, these two little idiots were tricked by Malfoy, and were almost discovered by Filch. They ran into the corridor on the fourth floor in a panic, and then found a huge three-headed dog inside. They were so frightened that they ran away in a panic.

return.

Hermione was very angry and cursed them. Ron and Harry were naturally unhappy, but they didn't care about her. They started discussing what the three-headed dog was guarding.

Erwin did not participate in the conversation. It would be outrageous if first-year students had to worry about the care of Hogwarts treasures.

On Friday morning, Sabi came back and brought Erwin a product flyer from the Diagon Alley drugstore. This guy stood on the dining table with his mouth wide open, like a baby bird begging for food, until Erwin fed him three sticks.

The sausage then flew back to the owl loft with satisfaction.

"Meerkat potion, enhanced endurance and water resistance, giant power oil... a total of fourteen potions are used comprehensively, personally prepared by a senior potion master. If used continuously for more than two years, one can obtain a physique close to that of a centaur. The total cost is...

…one thousand and forty-two galleons.”

Erwin felt a bit toothache. If he hadn't smelted all the two thousand galleons, he might have considered it.

Although he has long wanted to find a way to make money, it is too unrealistic for a first-year Hogwarts freshman to want to make money from the wizarding world. The Frost family's wealth cannot provide him with support, and conventional society

The items inside are of too little value to wizards.

The only official newspaper in British society, the Daily Prophet, sells for only five bronze nats per copy. Even if wizards across the country subscribe to the newspaper, the daily sales are only over one hundred galleons.

However, there is no rush for the time being. There are not many people in the wizarding society who can directly spend a thousand galleons, so these potions can most likely be prepared with confidence, and the material cost will definitely be much cheaper than the finished product.

Erwin returned the tomes on magic research to the library, and then stayed there for a whole morning. He did find several pharmaceutical formulas on drugstore leaflets, but they were all marked as requiring extremely advanced skills.

Potion brewing techniques.

The reason why potions are called magic potions is because the wizard needs to use his own magic power in the process of material processing and brewing. This is why the little wizards must learn prescription by prescription, which is even more difficult than learning spells.

Much more difficult.

In this magical world, only wizards are the absolute main body of production.

In addition to these potion formulas, Erwin also wanted to know if there were spells such as invisibility. If he wanted to be able to move freely in the school at night, he must at least have some corresponding abilities.

As expected, I found nothing. This is normal. No normal school would put agent training materials in the library.

Erwin didn't take it seriously. He returned to the dormitory, took out a stack of letter paper from his suitcase and started writing (he really couldn't use rough parchment.)

Professor Stewart:

Tell Mr. Dipper to write down all the spells he used to escape capture from the Death Eaters and the Ministry of Magic in the past few years and send them to me.

After putting the letter into the envelope, Erwin thought for a moment, took out the can of Fountain of Power from the suitcase, and carefully poured a little into a small test tube.

Since Galleons can be converted into Fountain of Power, let's try to see if we can convert the Fountain of Power into Galleons.

With these in hand, he rushed to the owl shed on a hillside outside the castle and found Sabi. No owl dared to approach within two meters of this eagle owl. It seemed that it had become the dominant figure in Hogwarts due to its size.

Erwin tied the package containing the test tubes to its leg, then put the letter into its mouth and let it hold it, "Take the one on your left leg to the Diagon Alley drugstore and write the letter to Professor Stewart."

Sabi stared at it with wide eyes and accused him of using the owl as a livestock.
