Hermione, let's start a revolution from Hogwarts!

"Dark magic defense...defense spells, do you know what they're usually used against?"

He forced a smile, wanting to make a good impression in the first class, but unfortunately, the Slytherins, encouraged and led by Malfoy and others, didn't give Quirrell any face.

Some of them mocked, "Why are you wearing that headscarf?"

"This was a gift from an African prince to thank me for defeating a resurrected zombie. Anyway... does nobody know anything about Defense Against the Dark Arts?"

Nietzsche's gaze shifted slightly downwards, revealing Quirrell's fingers repeatedly stroking the gauntlet of his wand.

In certain situations or emotional states, many people's bodies will involuntarily begin to repeat a certain action in order to seek pleasure, maintain balance, and prevent themselves from losing control of their emotions.

For example, Malfoy would shake his leg, Hermione would tap her fingers on the table, and Watson would twirl his cane...

"In order to resist dark creatures, black magic, and the practice of dueling."

“That’s right, but you weren’t quite right, so I can only give Slytherin two points.” Quirrell breathed a sigh of relief and stammered, “Not a duel, but… a battle.”

The answer wasn't perfect; you can see that by simply opening the book, he was happy because someone was willing to support him.

Because of his stutter, not many people wanted to listen to Quirrell's lectures. Not to mention, if Quirrell walked even a little to the back of the row, he could hear their gossip and ridicule of him.

So it is quite clear that Quirrell and Nietzsche both "isolated" the Slytherins.

"Professor, I have carefully reviewed the classification of spells. Apart from white magic, most of the spells that can serve a defensive purpose are classified as black magic curses, poison spells, and curses."

In "Black Magic: A Guide to Self-Defense", besides the Spark Charm which is like a flare and the Smoke Charm which has the effect of a smoke bomb, the most classic knockback charm is also a kind of black magic.

Not to mention the subsequent Shattering Curse, Stunning Curse...

Quirrell seemed to have a headache. He rubbed the sides of his head with both hands and then straightened his headscarf.

"In fact, due to its direct destructive power, some forms of dark magic are classified as 'teachable spells' by the Ministry of Magic, while others are..."

"Then it is the strongest curse—the three unforgivable curses."

“You…you really are clever.” Quirrell glanced around nervously, then said haltingly, “That’s right, the Unforgivable Curse requires the caster to maintain intense hatred, like the hatred you feel for those people to die…”

As he finished speaking, fear suddenly welled up in his eyes, and he immediately stopped.

"I'm sorry, this isn't even what you've encountered yet... I'm sorry, I'm sorry." He muttered several times in a low voice, his head down, as if he were talking to Nietzsche.

"So, the academic community's distinction between black magic and the classification of curses, poisons, and spells is based solely on the negative effects caused by magic?"

“That…that’s one way to understand it.” Quirrell’s forehead was covered in sweat, and his face was pale.

Nietzsche recalled his previous lessons on spells, pondered for a moment, and offered some of his own conjectures.

"What if I use a standard spell imbued with strong negative emotions to make it somewhat dangerous?"

Chapter Twenty: The Dark Side of Magic

Unbelievable?

No, it should be something unheard of.

No wizard... not even the renowned professors of Hogwarts in academia would think that way.

Because spells like the Summoning Spell, Levitation Spell, and Lockpicking Spell were created by wizards to 'take it easy', they seem to be born to help wizards and have no harmful properties.

Naturally, no one would associate such spells with black magic or white magic.

As long as you're not a Squib or a Muggle, even if you memorize the incantation and develop muscle memory for the gestures, it will work as long as you do it correctly.

This is the kind of spell that's considered a fool's curse.

“How could you… Haha, nobody would think that…” Quirrell chuckled, as if startled by Nietzsche’s idea. “I mean, why not just use black magic?”

"Just for personal reasons."

Wands with unicorn feather cores are the least likely to succumb to dark magic and are the most loyal among all wands, regardless of whether their first owner was a highly accomplished wizard.

As a naive and impetuous young man, Nietzsche had no idea what dangerous things he was saying.

He simply felt that this kind of discussion was as ordinary as discussing with his two fathers which weapon was most popular with the army during the war.

"It's like I used a spell to make the table float, but I feel... I could grip the table a little tighter..."

"Then it will shatter, why not just use a shattering spell?"

“But I can make it shatter or not, it’s all up to me.” Nietzsche gave a prime example: “Like an automatic rifle, I can choose the type of bullet it fires.”

Perhaps because he realized that the person in front of him was a wizard, he felt it was not a safe bet.

But strangely, Quirrell quickly understood Nietzsche's thoughts:

The Smash Spell is like a giant trap; it only causes damage when its prey steps into its range, just as a spell must hit to cause an object to shatter.

Admittedly, the Shattering Charm can be dodged, but the Levitation Charm acts directly on objects.

"So you want to just build a hunting rifle and equip it with regular hunting ammunition and armor-piercing rounds?"

"You know..."

“That’s right, I… I was originally a professor of Muggle Studies.” Quirinus Quirrell said somewhat embarrassedly, his hands tucked into his pockets like a squirrel. “Then you should have established the direct relationship between magic and spells first.”

This is the Ravenclaw way of thinking.

Although they are eccentric compared to ordinary people, they have very agile thinking, and intelligence, vision, and a love of exploring their favorite things are the most obvious characteristics of Ravenclaw.

Quirinas Quirrell, as a mature Ravenclaw, certainly was.

"The essence of the Levitation Charm is gravity or control, the interaction of magic with objects, and the comparative experiment of emotions and standard spells... There's too much to cover; you need to try them one by one."

"Professor Flitwick said you can help me complete it."

Kechiro did not immediately respond. Even after hearing the former dean's name, he merely swayed slightly, his hands constantly pressing behind his ears.

Perhaps he had a headache... Nietzsche could only guess.

"Let me think about it." Quirrell's headscarf, the part touching his forehead, was already soaked with sweat.

He resumed his lecturing haltingly, but his mind was elsewhere. As if possessed by Professor Binns, he stood listlessly at the podium, reading from the textbook verbatim.

Until the bell rang to signal the end of get out of class.

Without receiving approval, Nietzsche could only pack up his books and put them in his backpack. When he was the only one left in the classroom, the professor called him back.

"I see why Professor Sprout and Professor Flitwick often mention you. Look... it seems you're very curious about magic. That's alright, I... I used to be like that too..."

"I've been thinking about it, and this seems like a good research direction. Anyway, first-year students only have one Defense Against the Dark Arts class a week. How about this, you come sit here with me before curfew every night?"

This timing sounds perfect.

It won't conflict with professors' courses or courses in other colleges and for senior students, and after sufficient thinking before bed, sleep quality will be greatly improved.

What a pity...

“But I have Snape’s detention at night, Professor,” Nietzsche said, sounding somewhat aggrieved.

“It’s alright, I’ll talk to him about it.” Quirrell waved his hand and walked up the spiral stone staircase at the front of the classroom. “This is a very important academic matter. Time is money, my friend.”

The classroom staircase leads directly to the office on the third floor. Quirrell leans against the handrail and slowly makes his way up the empty classroom.

The action of pushing open the door seemed to be the last bit of strength he had left, because the moment Quirrell stepped into the Defense Against the Dark Arts professor's office, he collapsed limply onto the carpet.

The muscles begin to ache and feel sore due to spasms.

"A Mudblood... It's a pity he's a genius, just like me back then. I can smell his ambition. No wonder he's Slytherin..."

The hoarse, low voice wasn't Quirrell talking to himself, because his lips were pale and he was lying on the ground convulsing.

In fact, it came from inside Quirrell's headscarf.

"Master, I was wrong... I was wrong, please forgive me."

"Hmph, I told you to agree to him, and you still resisted." Some black smoke wafted out from the gap in the headscarf. "Quirok, only power and strength are real. You have no choice."

"No, no... I'm just worried about attracting unnecessary attention; he's not part of the master's plans."

Perhaps Quirrell was right. The pain, like being bitten by insects in an Egyptian torture, gradually subsided, and he finally caught his breath, turned over, and stared blankly at the chandelier on the ceiling.

Yes, he has no other choice now.

“It’s alright. Give a smart person like that a little benefit and he’ll naturally discover the secrets of black magic…” Her voice began to weaken again. “Fool, don’t mess things up.”

"Master...Master?"

Quirrell called out several times, but after receiving no response, he changed into new clothes.

After resting for half a day, I decided to leave the office.

Hermione, on the other hand, did not fare so well compared to Nietzsche; she even somewhat regretted joining Gryffindor.

Aside from Nietzsche, whom she had met before the start of the semester, Harry and Ron met on the train. Just when she thought everything was going smoothly and she was about to begin her wonderful school life, a problem arose:

The long-standing relationship between Gryffindor and Slytherin has been passed down smoothly.

"No, no, no, no, Nietzsche added almost all of Slytherin's points!" Ron wailed, staring at the house hourglass. "Hermione, couldn't you have made him add less...?"

"Do you want him to be someone who commits all sorts of evil deeds, someone that every professor would shake their head at?"

Ron Weasley was about to nod, but when he saw Hermione standing with her hands on her hips, glaring at him, just like his own headmaster, he was stunned.

So... he's starting to follow his heart.

“I added ten points yesterday and five this morning, but your two brothers lost twenty in one night!” Hermione turned to Harry and said, “I know you’d love to go for a night out, but you’d better not get caught…”

Harry couldn't understand how Nietzsche could tolerate her.

"By Merlin, I did not come to Hogwarts to change locations and enjoy the same treatment as I did at the Dursleys'!"

"Can't you have a little patience? If it's Nietzsche, he..."

"This is the third time you've said that in just two days since school started." Harry counted on his fingers, thinking carefully. "Yes, we already know that if it were him, he certainly wouldn't be impatient."

Hermione's cheeks flushed slightly after being shoved in the mouth.

The doors to the foyer were wide open, and a cold September wind swept in from the valley. Hermione put her hands in her pockets.

“Maybe he’s out at night too, you just don’t know it,” Ron retorted as he walked into the auditorium. “Don’t forget, he’s not in the same college as you now.”

"Impossible, he wouldn't be that bored!"
