The Magical Principles of Natural Philosophy at Hogwarts

"Where do you have the guts to teach me a lesson?" Malfoy's eyes showed a hint of anger, and the other party's attitude had already angered him.

Gryffindor students are annoying enough, and Gryffindor Muggles... are like toilet molluscs.

"If I remember correctly, I really don't think I offended you." Erwin looked serious, "Why did you come here to trouble me?"

"I'm happy." Malfoy sneered.

"Now that you have let the prefect deduct our points, does that mean we can go now?" Melanie asked at this time.

"What joke are you talking about, little bastard?" Melanie's eyes flickered when she heard this insulting name, but Malfoy was still ignorant, "It's really stupid of you to come here on your own initiative. There won't be any professors to back you up in the woods... Crabbe, Goyle!"

The two stout followers stepped forward together. Although Erwin already had a figure close to that of an adult, the height of the two men of the same age was no less than his, and their width was twice his.

"Take off this guy's clothes and throw him into the Black Lake." Malfoy looked at Erwin with a nasty smile.

He has long been unhappy with this guy.

"Why do you have so much malice towards me?" Erwin frowned, "Just because of my Muggle origin?"

"Mudbloods should know their identities, you are not qualified to touch magic." A cold snort of contempt.

"I'm curious, if Harry Potter and Ron Weasley were here, wouldn't you do the same to them?" Melanie asked suddenly at this moment.

"Then... definitely." Looking at the other party's exquisite face, Malfoy's mind suddenly became confused, and he actually answered this question, but his tone was a little guilty.

He actually didn't dare, because Ron had the entire Weasley family behind him, and Harry had Dumbledore behind him. It could even be said that the entire British wizarding society would support the boy who lived.

Only little Muggle-born wizards are truly helpless, and there is almost no price for bullying them, because most people dare not speak out after being bullied.

Although Brother Yan has a bad personality, he is not stupid.

"Master Malfoy, what is she going to do?" Crabbe pointed to Melanie.

Malfoy hesitated, "Throw them into the lake too." He said grimly.

No matter how beautiful she is, she's just a lowly Mudblood.

Crabbe and Goyle looked at each other, and with a twisted pleasure in their hearts, they grinned at Melanie.

They geared up and walked towards Erwin and Melanie, obviously more used to solving problems with brute force than wands.

Erwin sighed, it seems that all the second generation ancestors seem to have the talent of self-taught.

He really didn't want to beat up the kid.

"Do it, Senior Eisner." Malfoy also shouted to the senior seniors beside him.

"This...isn't that good." Eisner hesitated, obviously he didn't have the consciousness to be a thug at this time.

"If you want an introduction from my dad, you'd better do what I tell you." Malfoy gave him a savage look.

Eisner froze.

He is already in the seventh grade, so he should think about things after graduation. He is not from a magical family. If he wants to make a fortune, it seems that he can only rely on the Malfoy family, so...

He pointed his wand at Erwin, "Sorry, don't resist, I don't want to hurt you."

Brother Yan had already made a move at this time, "Oolong comes out!" He yelled.

A black cobra appeared, which should be some kind of transfiguration application.

And Erwin, who was originally unarmed, suddenly had a wand in his hand. To be a wizard, you must draw your wand quickly. "All petrified!"

Spells with no real damage like Petrification and Stunning can be very useful in fights where hazard control is needed.Erwin could actually say the spell without having to say it aloud, but obviously there's no need to reveal the fact that he can cast it silently.

Goyle and Crabbe were hit by the petrification spell. Given their size, there is no possibility of dodging. Of course, petrification does not really turn people into stones. It should have an effect similar to blocking nerve signal transmission.

Then the two mountains of meat flew up and slammed into the rear. Master Malfoy, who was caught off guard, was immediately crushed underneath. The wand was released from his hand, and the summoned poisonous snake also turned into a cloud of black mist under the crushing pressure. dissipated.

Eisner was also hit. He never expected a second grader to be able to cast a spell so quickly. Mr. Crabbe's body seriously obstructed his sight. He didn't use spells indiscriminately, but made a very rational choice .

"Armor protection!"

He is already a seventh-grade student, and he is still a prefect. Naturally, he can use regular spells proficiently. The armor spell can withstand several stun spells or petrification spells, not to mention that the opponent is only a second-year student. Cursing him is tantamount to being invincible.

Then he got punched hard on the nose.The armor curse does not form armor in the actual sense, it can only counter other magic to a certain extent.

Using fists in a wizard duel is called... "Don't talk about Wude"?

Eisner wanted to complain, but his brain was buzzing, and he subconsciously covered his bleeding nose, and then he got another knee bump in the stomach.So he arched his back like a prawn again, bending down in pain.

Instead of continuing the attack, Erwin took his wand from Eisner's hand without much effort, and with a slight push, the Hogwarts seventh year fell to the ground convulsing, completely useless .

Erwin shook his head, isn't Hogwarts' combat teaching too lacking?It's already seventh grade, but it still feels like a delicate greenhouse flower.

Master Malfoy over there finally pushed away Goyle who was lying on his body like a dead pig, stood up angrily, and then found that Eisner he was relying on had been dealt with, and was stunned.

Erwin pointed at him with his wand, and an invisible force was generated, and Malfoy's body floated up. He screamed in horror, waving his limbs, but touched anything that could borrow the force.

"Put me down, you bloody Mudblood! My dad..."

Erwin figured that just letting him float seemed less controlling and humiliating, so...

He drew a half circle with his wand.

Malfoy's body also immediately turned 180 degrees, and turned into a head-down state. The robe covered his head under gravity, but it didn't reduce the volume of his yelling.

"You're finished! You're finished!" The humiliated classmate Yan Ge was furious.

"I still don't know much about the upper-level system of Hogwarts. What kind of rights does a school manager like your father have?" Erwin asked.

"Most of the funds for this school are provided by my father and eleven other school managers! Hogwarts would not be able to run without them!" Although he was suspended, Malfoy still spoke arrogantly, "Even the headmaster has to show respect to my dad! You're screwed! My dad will get you expelled straight away! They'll break your wand and send you back to the Muggles! Put me down now!" !"

"It's scary." Erwin said, but there was no look of fear. "Does that mean that if I put you down, our grievances can be written off?"

"dream!"

"That is to say, I offended you, no matter what, there is no good fruit to eat?" Erwin spread his hands in a helpless tone.

"You beg me, humbly beg the Malfoy family's forgiveness!" Student Yange became more and more proud.

Erwin sighed, "Honorable Master Malfoy, haven't you realized that such rhetoric actually makes it easier for me to take some... extreme measures?" His tone instantly became cold.

Brother Yan was stunned for a moment, then immediately lifted the hem of the robe covering his head with his hands, and then saw the magic wand that was almost stuck on his forehead.

All the arrogance and anger disappeared without a trace, and the essence of cowardice was exposed, "What are you going to do?" He was so frightened that his voice changed.

Although this guy in front of him is a second-year student, he can easily subdue Eisner, so there is no guarantee that he will cast a terrible curse!

"You asked for it. Forget it."

Malfoy froze as the Forgetting Spell was cast, the hem of his robes falling back over his face, and a few seconds later he said in confusion, "Where am I..."

He lost his memory of this period.

But Erwin felt dissatisfied, "Forget everything."

"I am..."

"Everything is forgotten."

"I……"

"Everything is forgotten."

"..."

After the fourth Oblivion, Malfoy stopped talking.Erwin lifted the hem of the robe that covered his head, and saw the guy's eyes were blank, with a dull look.

"Did you use the Amnesiac so many times to turn his brain into a paste?" Melanie asked curiously.

"How is it possible." Erwin observed the state of Brother Xiayan, "I just learned some methods of the Oblivion Curse from Lockhart, and it just happened to be used. Now you just need to tell Malfoy a story. The memory of time will be rewritten, the more detailed the details of the story, the harder it is for him to find out, it should be like this..."

"Then what story are you going to tell?" Melanie became interested.

"I haven't thought about it yet."

"Then I'll come."

There was a smirk on the corner of the girl's mouth.

……

Three hours later.Mrs. Huo Qi, a flight teacher, took the freshmen of the first grade to practice riding over the Black Lake.

"Keep in formation! Control the speed!" She held the handle of the broom with one hand and rested her wand on her chin with the other, so that her voice could be heard by all the students, "Get into your brooms, be careful Fall into the lake!"

"Ms. Huo Qi, there seems to be someone over there!" A Ravenclaw boy suddenly shouted.

"Which side?" As a professional Quidditch referee, Mrs. Hooch's eyesight is naturally excellent, so she immediately saw the scene on a hillside on the other side of the Black Lake.

"Merlin's beard." She gasped.

"Everyone, hover!" gave the order to the students, and she flew over there.

The scene on the hillside is fantastic, four Caucasian boys in only their underwear sleeping very close together, their skin glistening in the afternoon sun.There are a pile of medicine bottles on the ground, and the liquid left in them exudes a sweet and psychedelic atmosphere.

And the green and silver snake badges are very conspicuous on the few school uniform robes scattered around.

, "Merlin's beard, young people nowadays are really..." Mrs. Hooch sighed again.

She straightened her face and looked at the students in the sky, "Everyone is forbidden to make noise!" She said solemnly, the whispering of the students stopped, and they all looked at the four people with extremely strange eyes.

"Cornelius." Madam Hooch named the boy who was the best at flying, "Hurry back to the castle and invite the Slytherin head, Professor Snape."
