The Magical Principles of Natural Philosophy at Hogwarts

A stream of air suddenly appeared.

Erwin doesn't need to create a strong wind, but only needs a strong airflow to the Hufflepuff stands. With his current level of magic power, this is not a difficult task.

The Hufflepuff students in the stands were not affected too much, but on the top of the mast with the college flag hanging, a translucent short figure staggered, squatted down and hugged the mast, and almost didn't fall.

That seemed to be a... house-elf?

The wind subsided, the little creature stood up and became invisible again, Erwin turned his head to look at the field, Harry was still being chased by the Bludger, and Malfoy didn't take this opportunity to find the Snitch, but walked around Potter taunted him while flying.

A house-elf who takes the initiative to harm a human wizard?interesting.

Erwin looked around, and there seemed to be no one to count on, and it was too slow to go to the rostrum to report to Professor McGonagall.

It seems that I still have to do it myself.

There is still a long distance between the two stands. Even if the range is sufficient, it is difficult to guarantee the hit rate. What's more, firing a spell from such a distance is too eye-catching, and it may cause some misunderstandings.

Erwin thought for a moment, first took off the too iconic golden-red scarf, then put on the hood attached to the robe, and used a simple spell to cover his face with a faint layer of black that could obstruct his vision. Mist, wizards naturally do not need masks to cover their faces.

Then, there are the four curses of stealth.

He doesn't want to attract too many people's attention.

Neville's attention was all on the court, "It's over, we've lost forty points, Erwin, Erwin?"

He turned his head and looked suspiciously at the suddenly empty seat beside him.

Erwin had arrived on the platform behind the auditorium at this time. It was quite spacious and there were no people there, and his goal was naturally the platform on the Hufflepuff side.

If you go down the stairs, and then climb the stairs on the Hufflepuff side, it feels like you have learned magic for nothing, so Erwin plans to fly over.

In fact, flying does not necessarily require a broomstick. Not-so-advanced magics such as floating spells and inflatable spells can lift gravity restrictions, but floating and flying are naturally not a concept, and one or more additional spells are required to produce effects In order to have the ability to move freely in the floating state.

For the vast majority of wizards, being able to maintain the effects of two spells at the same time is already a very good level of magic. Many people are not unable to fly, but they have no way to do other things when flying with magic, so they will naturally fly. More inclined to use broomsticks or other flying tools.

Erwin also has this feeling now, that is, one of the main directions for improving magical power is to allow more magical effects to take effect at the same time, that is, multiple casting.This is also the value of rune items, they can directly provide wizards with the benefit of one or several spells.

Like Erwin's Armor Ring.

Using the floating spell to reduce his own gravity, after gaining enough height, Erwin used the hurricane spell to create a soft airflow behind him, and his robe played the role of a sail to a certain extent, with this force , without making the slightest movement, he glides to the Hufflepuff stand.

The landing was successful.

Without a moment's hesitation, Erwin aimed his wand diagonally upwards, and shot a stun spell.

Although the other party was also invisible, of course he still remembered the location of the house elf.

The Stunning Spell hit, and the little thing screamed, but it just burned and showed no signs of fainting.

Unexpected, very strong magic resistance.

Erwin was only stunned for half a second, then immediately changed his plan and quickly imprisoned him!

The imprisonment spell can create a substantial rope, which is essentially a copy and deformation of the material of the wand itself. Although the created rope is time-limited, it is still material, which means that it will not be affected by the target's magic resistance. Weaken the effect.

The house elf was trapped, and Erwin finally saw its face clearly. From a human perspective, he couldn't immediately tell the difference between the other elf and other elves.

The little guy screamed again, and fell from mid-air. The moment it landed, it suddenly disappeared with a slight crack.

Elvin was ready to deal with its counterattack. After all, this is a house elf who can actively attack human wizards, but it actually apparated and escaped?

The stadium was very noisy, most of the students were focused on the two teams, only the Hufflepuff students in the back row heard the abnormal noise and turned their heads.

But all they saw was an empty platform.

When Erwin returned to the Gryffindor stand, he found that the students here began to cheer. That's right, while Erwin dealt with the house elf, Harry actually directly caught the golden snitch, Gryffindor Won.

Many people flocked to the stadium to celebrate. Erwin was really not interested in participating in this occasion. He waited outside the stadium until he saw Professor McGonagall.

"The Bludger that hit Harry was artificially manipulated," Erwin said succinctly.

Professor McGonagall made a silent gesture, "Come to my office later, I'm going to take Harry to the infirmary now." She whispered.

Erwin looked behind her and saw that Harry was lying on a stretcher being carried by the Weasley brothers. "What's going on?" he asked subconsciously.

"Professor Lockhart made a very serious mistake, using the Vanishing Charm to heal Harry's broken bones."

Erwin couldn't help but marvel, this arrogant idiot really can do anything.

Two hours later, in the Gryffindor dean's office, Minerva McGonagall had learned the details from Erwin.

"I don't allow you to investigate the elves at Hogwarts. They have always been dedicated and dedicated to serving the school. Their emotions are actually very fragile. For them, your investigation is to question their character and ability to work. They will even punish themselves for it." Professor McGonagall's attitude was firm.

"But the house-elf who attacked Harry was able to apparate in Hogwarts." Erwin said slowly: "This shows that it is very familiar with this castle, and it is very likely that it itself work in school."

"Although the Hogwarts prohibition mainly prohibits the apparition used by wizards, only house elves with strong magic power can not be restricted by this restriction," Professor McGonagall shook his head slightly, "Castle None of the elves in the book have this level of magic."

Erwin recalled his ineffective stun spell, "So which breed of house-elf is the most powerful?"

"Generally speaking, house-elves who come from a magical family and have been passed down through generations will have stronger magical powers."

"An elf from a magical family, and at the same time very familiar with Hogwarts..." Erwin pondered for a while, "Professor McGonagall, can you tell me who is the Hogwarts board of directors, who are they?" What is their family background?"

Professor McGonagall was silent for a while, "You are just a child, Erwin, so you don't need to worry about it. Thank you very much for your help to Harry. Please believe that your professors will handle this matter well."

Her attitude is a little tough.

"I think Draco Malfoy is very suspicious." Erwin said bluntly: "He instructed his family's elves to attack Harry during the Quidditch match, which is a very reasonable speculation."

"Enough, Erwin. Don't speculate on your classmates with such malice." Professor McGonagall said with a little helplessness in his tone, "I can't punish another student based on your one-sided words."

Meaning the capture of the house-elf is only valid proof?Erwin didn't insist either, "I just hope you can understand, professor, the attack on Harry is not as simple as it seems on the surface, it is likely to be related to the recent rumors of the secret room, I feel the breath of conspiracy... "

Professor McGonagall was angry and funny for a while, and the child actually looked like she wanted to instruct her professor to do things, "Okay, Erwin, you should go back to rest, and I and other professors will handle this matter properly."

Erwin sighed, "Okay, goodbye, Professor."

He walked out of the office and closed the door.

From Professor McGonagall's reaction and the information he knew, Erwin roughly understood the school board's influence on the school.

Hogwarts needs continuous funds to run a school, and the sources of funds are only the Ministry of Magic and the school board. Even the headmaster is constrained by the school board. Although he is the most powerful wizard in Britain, he is on the side of order. Order must be followed, even if this order is not sufficiently just and reasonable.

Erwin didn't follow Professor McGonagall's order to go back to rest, turned around at the stairs, went down to the second floor, and then walked to the office of the Defense Against the Dark Arts class.

He pushed the door directly and walked in.

Lockhart was obviously frightened when he saw him, "You... what are you doing here again?" His face was frighteningly pale.

"I heard that Professor, you just made a fool of yourself again?" Erwin asked back.

"It's just a small mistake, a small mistake." Lockhart still insisted.

Erwin didn't expose him, and left him a pair of underpants, "This is not acceptable, Professor Lockhart, if you come here a few more times, the whole school will know your true level. But it’s all about to be lost.”

Lockhart's face grew even paler, and his lips began to tremble slightly.He didn't know what this scary young man was going to do again, was he going to blackmail him again?

He no longer has any thoughts of resistance, knowing that the opponent is impossible for him to defeat.

However, Erwin's next words were completely beyond his expectations, "Since you have an urgent desire for fame, then I can help you, have you found that there is almost no protection for falling players on the Quidditch pitch?" Facilities? You can suggest to Professor McGonagall that you are responsible for improvements, such as permanently deforming the ground into an elastic material, and applying a slow-fall force field above the ground."

There was a light in Lockhart's eyes, this plan is feasible, as long as it is completed, everyone who comes to the Hogwarts Quidditch pitch will know his name Lockhart, and no one will remember him The embarrassment of losing a student's bones.

But after all, he still has some self-knowledge, "But this kind of improvement... I can't do it."

"Of course you can't do it." Erwin didn't give him any face, but then changed the subject, "But I can help you."

"What?" Lockhart thought he had heard wrong.

"I've always been a person with clear grievances." Erwin said slowly: "Although you said how much you offended me, you still satisfied my request after all, then I will reward you and give you what you want the most. Fame."

He tilted his head slightly, and the half-smile expression made Lockhart shiver uncontrollably, "What's more, you maintain your reputation, which is good for us, isn't it?"
