A certain Hogwarts professor of runes

The light from the spell, like a rosy sunset, illuminated the faces of every young wizard.

The spell, as if it were a tangible incantation, crackled and popped, reflecting off the castle walls a dozen or so fine, twisting snakes that looked like arcs of deep red electricity.

These 'little snakes' extended onto several nearby suits of armor, and the spears and blades in their hands flew out of their grasp.

"Hiss hiss hiss!"

The spears and blades drew arcs in the air before crashing into the open ground in front of Felix, piercing several deep holes in the makeshift gilded stage.

The wizard: "..." His face showed a bewildered expression, as if he were in a dream.

Who am I? Where am I? What have I done?

Why do I have to see this?

Felix put away his wand and, addressing the silent students below, said in a relaxed tone, "The same spell, cast by different wizards, can have completely different effects—I intend to tell you this when you have a better understanding of duels."

"However, it doesn't seem too early now," he added.

The young wizards felt a chill run through them, as if they had swallowed a dozen ice-cold candies.

Professor, are you sure you're not trying to discourage your students? Look at that wizard's stunned expression...

"Professor, how did you do that?" Abbot Balk asked, his mentality a little broken. Influenced by his family, he aspired to become an Auror and had worked hard in that direction since childhood, mastering a lot of dueling spells.

Even his uncle, who was an Auror, praised his talent, but now he is deeply mired in self-doubt.

Was his decision too hasty? The outside world might be more dangerous than he imagined. At least, he and Professor Hyp were only three or four years apart, but he didn't think he could use the Disarming Charm to that extent in three or four years.

Never in my lifetime!

What makes him so confident in becoming an Auror and fighting against dark wizards? Won't he just get hammered by the dark wizards?

Various thoughts raced through his mind, but Professor Heap comforted him at the right moment, saying, "Mr. Balk, you need to change your perspective—"

"For ordinary spells, such as life magic, simply knowing how to use them is perfectly sufficient; but for spells that can protect you, you need to invest a lot of time and effort, and you can never take them too seriously."

“As far as I know, new Aurors undergo rigorous training. For example, they might practice the Ironclad Charm thousands of times,” Felix said, looking at him. “But that’s something for after you become an Auror. At your age, your spells are already quite good.”

Balk fell into deep thought. He thought about how he always fell just a little short when he sparred with his uncle, and how he seemed to be able to defeat his uncle with just a little effort.

But for the past two years, he had always fallen "just a little bit" short. He suddenly realized that becoming an Auror was not as easy as he had imagined.

"Thank you, Professor Hyp," Balk said to Felix.

On the other side, Cedric Diggory raised his arm and asked, "Professor, can we also achieve what you're like through repeated practice?"

Many young wizards had hope in their eyes. "Professor, if you say so, we'll definitely boost its power!"

Snape scoffed at the question, but he was equally curious about Felix's answer.

"Hmm... This is not an easy question to answer. The power of a spell involves many factors. Once you go back and carefully read the study materials you have, you will have a better understanding of what I'm saying."

"I've found that most people don't actually have high expectations of themselves; they're fine as long as it's usable."

"But beyond 'barely usable,' there's the skill of mastering it, casting spells silently and without a staff, and adjusting it to suit personal habits..." Felix shook his head. "There are too many techniques to figure out."

Felix clapped his hands. "Alright, I'll go into detail about this in the next lesson. That concludes today's lesson."

The young wizards left the Great Hall as if they had lost their souls. Professor Hyp's magic tonight had shocked them too much. They never imagined that the same spell could be used so differently by different people.

Professor Snape approached, and said with a mixture of surprise and reserve, "Felix, I didn't expect you to be so selfless."

Felix did not speak.

Was he truly selfless? No, the contents of the parchment were merely the minimum requirements to ensure they learned the spell, and that had absolutely no effect on him.

Even if he selects some elites in the future to impart more advanced knowledge, how many of them will actually be able to learn it?

He was not afraid of the emergence of geniuses; on the contrary, Felix looked forward to the appearance of more dazzling young wizards.

His strength has never been limited to a single spell.

So Felix joked, "Professor, perhaps I'm trying to gain their favor and cultivate my own power base!"

Snape's expression suddenly froze. He silently scrutinized Felix, trying to determine the truthfulness of his words.

"Ahem, don't be nervous, I was just joking."

……

Harry, Ron, and Hermione were walking back when Ron, holding the information about the 'Disarming Charm,' said, 'Does this thing really work?'

"Of course, that's how I learned Transfiguration," Hermione said, wearing a knitted hat.

Harry asked her, "Do we have to fill out all sorts of forms like you did?"

Hermione had to explain, "That's so we can better understand our weaknesses and practice accordingly. Harry, I think you're almost there."

"Just a few sparks," Harry said, somewhat frustrated.

"Oh, Harry, this is a sign that the Disarming Charm is about to succeed. It's mentioned in the information. Maybe you'll succeed next time," Hermione said to him.

The little witch's words cheered Harry up. Maybe he should try harder when he got back?

On Friday morning, the effects of the second dueling lesson were still building.

However, rumors had already spread among the young wizards that "Professor Hyp used a disarming charm to blow up a section of the Great Hall wall," which led Felix to notice at lunchtime that some of the young wizards who hadn't attended class were giving him strange looks.

Fortunately, the weekend arrived quickly.

Felix accepted Professors Flitwick and McGonagall's invitation to a gathering at the Three Brooms.

When he walked into the bar, he was surprised to find Snape there as well.

"Felix, come here." Flitwick stood on the chair and greeted him warmly. "We were just talking about Damocles Bellby."

Felix sat down and asked curiously, "The news has been released? I mean, about the wolfsbane medicine."

"You know too?" Professor Flitwick said with some emotion after receiving an affirmative reply.

"Belby was outstanding when he was in school. I actually suggested that he pursue the direction of spells, although he eventually chose potions - at the time he was very much liked by Professor Slughorn."
