The Magical Principles of Natural Philosophy at Hogwarts

A stream of air suddenly appeared.

Erwin does not need to create strong winds, but only needs a strong airflow to hit the Hufflepuff stands. With his current level of magic, this is not a difficult task.

The Hufflepuff students in the stands were not affected too much, but on the top of the mast where the college flag was hung, a translucent short figure staggered, squatted down and hugged the mast, almost falling.

That seemed to be a... house elf?

The wind calmed down, and the little creature stood up and became invisible again. Erwin looked back at the field. Harry was still being chased by the Bludger. Malfoy did not take this opportunity to find the Golden Snitch, but circled around.

Porter flew while taunting him profusely.

A house elf who actively harms human wizards? Interesting.

Erwin looked around, and there seemed to be no one around who he could count on. It would be too long to run to the rostrum to report to Professor McGonagall.

It seems that I still have to take action myself.

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

Erwin thought for a moment, first took off the iconic golden-red scarf, then put on the hood attached to the robe, and used a simple spell to cover his face with a light layer of black that could obstruct his vision.

Fog, wizards naturally don't need masks to cover their faces.

Then, there are the four stealth spells.

He didn't want to attract too much attention.

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

He turned his head and looked at the suddenly empty seat next to him in confusion.

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

If you go down the stairs and then climb the stairs on the Hufflepuff side, it will feel like you have learned all the magic in vain after running so long, so Erwin planned to fly over.

In fact, flying does not necessarily require a broomstick. Less advanced magic such as the levitating spell and the inflatable spell can relieve gravity restrictions. However, floating and flying are naturally not the same concept, and one or more additional spells are needed to produce the effect.

Only in this way can you have the ability to move freely in the floating state.

For the vast majority of wizards, being able to maintain the effect 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 naturally

Prefer to use broomsticks or other flying tools.

Erwin also feels this way now, that is, one of the main directions for improving magic strength is to allow more magic effects to take effect at the same time, that is, multi-casting. This is also the value of magic items, they can directly provide wizards with

A buff to one or more enchantments.

For example, Erwin's armor ring.

He used the Floating Charm to reduce his own gravity. After reaching enough height, Erwin used the Hurricane Charm to create a soft airflow behind him. His robe acted as a sail to a certain extent. With this force

, he glided to the Hufflepuff Stand without making any movement.

Landing successful.

Erwin didn't hesitate for a moment, pointed his wand diagonally upward, and fired a stun spell.

Although the other party is also invisible, of course he still remembers the location of the house elf.

The stun spell hit, and the little thing screamed, but it was only burned and showed no signs of fainting.

Unexpectedly, very strong magic resistance.

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

The confinement spell can create a substantial rope, which is essentially a copy and deformation of the material of the wand itself. Although the rope created 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 could not immediately tell the difference between it and other elves.

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

Erwin was prepared to deal with its counterattack. After all, this was a house elf that could actively attack human wizards, but it actually disapparated and escaped?

The stadium was very noisy, and most of the students' attention was on the two teams. Only the Hufflepuff students in the back row heard the unusual noise and turned around.

But all they saw was an empty platform.

When Erwin returned to the Gryffindor stand, he found that the students here began to cheer and cheer. Yes, while Erwin dealt with the house elf, Harry actually caught the Golden Snitch directly. Gryffindor

won.

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

"The Bludger that attacked Harry was man-made," Erwin said concisely.

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

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

"Professor Lockhart made a very serious mistake and used the Vanishing Curse to treat Harry's fracture."

Erwin couldn't help but marvel, this arrogant fool could really do anything.

Two hours later, in the Gryffindor Dean's office, Minerva McGonagall had learned the specific situation from Erwin.

"I don't allow you to investigate the elves at Hogwarts. They have always fulfilled their duties and served the school conscientiously. Their emotions are actually very fragile. For them, your investigation is questioning their character and work ability.

They may even punish themselves for it." Professor McGonagall's attitude was firm.

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

Work within the school.”

"Although the restrictions at Hogwarts mainly prohibit the use of apparation by wizards, only house elves with strong magic powers can not be restricted by this restriction." Professor McGonagall shook her head slightly, "The castle

None of the elves here have this level of magic."

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

"Generally speaking, house elves who come from a magical family and have been passed down from generation to generation will have more powerful magic power."

"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 the Hogwarts school board is composed of?

What is their family background?"

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

Her attitude is a bit tough.

"I think Draco Malfoy is highly suspicious." Erwin said bluntly: "He instructed his elves to attack Harry during the Quidditch match. It is a very reasonable speculation."

"That's enough, Erwin. Don't speculate on your classmates with such malice." Professor McGonagall said with a little helplessness in her tone, "I can't punish another student based on your words."

Does this mean that only capturing the house elf can be considered as tangible evidence? Erwin did not insist, "I just hope you can understand, Professor, that the attack on Harry is not as simple as it seems on the surface. It is likely to be related to the recent

The secret room rumors are related, I feel the atmosphere of conspiracy..."

Professor McGonagall was angry and funny for a moment. This child actually looked like she wanted to guide her as a professor in doing things, "Okay, Erwin, it's time for you to go back and rest. The other professors and I will handle this matter properly."

Erwin sighed, "Okay, bye, 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 influence of the school board on this school.

Running Hogwarts requires continuous funding, and the only sources of funding are the Ministry of Magic and the school directors. Even the principal is constrained by the school board. Although he is the most powerful wizard in Britain, he stands on the side of order.

We must follow order, even if this order is not just and reasonable enough.

Erwin did not follow Professor McGonagall's order to go back to rest. He turned at the top of the stairs, went down to the second floor, and then walked to the Defense Against the Dark Arts office.

He opened the door directly and walked in.

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

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

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

Erwin did not expose him and left him a pair of underwear, "This won't work, Professor Lockhart. If you come here a few more times, the whole school will know your true level. The reputation you have accumulated so hard before

But it’s all going to be lost.”

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

He no longer had any intention of resisting, knowing that he could not defeat the opponent.

However, Erwin's next words were completely beyond his expectation, "Since you have an urgent desire for fame, then I can help you. Have you noticed that there is almost no safety protection for falling players on the Quidditch pitch?"

Facilities? You can propose to Professor McGonagall that you be responsible for improvements, such as permanently deforming the ground into an elastic material and applying a slow-fall force field above the ground."

Lockhart's eyes shone with light. This plan is feasible. As long as it is completed, from now on, everyone who comes to the Hogwarts Quidditch Stadium will know his name Lockhart, and no one will remember him anymore.

It's such an embarrassing thing to turn a student's bones into pieces.

But he still had some self-awareness after all, "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 heard wrongly.

"I've always had a clear distinction between grudges and grudges." Erwin said slowly: "Although you have offended me a lot, you still satisfied my request after all. Then I will repay you and give you what you want most.

Fame.”

He tilted his head slightly, and his half-smiling expression made Lockhart shudder uncontrollably, "What's more, if you maintain your reputation, it's good for us all, isn't it?"
