Hogwarts: My Spell Infinite Derivation

Chapter 91 The Essence of Spellcasting! God-level Techniques, Multiple Spellcasting!

"The King of Fireflies?"

Professor Flitwick nodded, with a hint of regret.

"I originally thought that young people these days would be more unconventional, like calling it Hogwarts or something like the Golden Flash."

"That's fine then. I'll fill out the membership information for you, and the badge representing your status as the King of Light will be delivered within two weeks."

Professor Flitwick's conversation with Shire about joining the British Wizarding Duel Club made some of the older students green with envy.

They are worried about where to find employment, and the British Wizards' Duel Club is an extremely popular but also extremely difficult option to get into.

Every wizard who becomes a member of the Duel Club possesses unique skills.

Even if these senior students only work as staff after graduation, they will still have many opportunities to access advanced magical knowledge in preparation for further studies.

Even if one is not interested in further study in the field of magic, dueling, as an ancient tradition, has a considerable following among wizards.

This means that the Duel Club has more sponsorships than it can spend, and working here offers generous salaries and excellent benefits, making it an absolutely top-notch place to work.

Unfortunately, the Dueling Club at Hogwarts might not be able to recruit even one person each year, as many positions are already filled internally.

But now, Ciel has directly obtained membership in the Duel Club?

This is so much better than the club staff that countless Hogwarts upperclassmen dream of!

For a moment, the students who knew his status and importance looked at Xia Er with a mixture of envy and jealousy.

But thinking about Charles's performance just now, the slight jealousy in their hearts vanished.

If two people are not too different, jealousy is easy to arise.

However, if the difference is so great that it is drastic, it becomes much easier to accept.

At this moment, as Charles looked at Professor Flitwick, he recalled the special armor spell that Flitwick had just cast.

"I asked tentatively," Charles asked.

"Professor, the Ironclad Charm you used to block my Laser Spell, I think I saw it instantly release three of them?"

When this was mentioned, Professor Flitwick's face showed an expression that said, "I knew you were going to ask that."

He stood with his hands behind his back, his face full of pride.

"That? That's one of my specialties."

"Whether it's the Ironclad Curse, the Stunning Curse, or most low-burden spells, I can cast several in an instant. Otherwise, how do you think I've won several consecutive dueling championships and firmly defended my title as the King of Gale?"

"Heh heh, relying solely on casting speed? Some well-trained wizards may not be slower than me, but when I get serious, they won't be able to catch up with my spellcasting speed."

Charles looked even more astonished.

He had assumed that the Triple Armor Charm he had just used was an improvement on the Armor Charm by Professor Flitwick.

As a professor of Charms at Hogwarts, it wouldn't be surprising for Shire to think that he could improve a single Charm or even create several unique ones.

After all, Snape was able to create the Upside-Down Bell spell when he was still in school, and he also created his signature spell, The Unseen.

If a student can do it, how could Professor Flitwick not be able to?

But Charles didn't expect that, according to Professor Flitwick, this seemed to be applicable not only to the Ironclad Charm but also to other spells.

Is this a unique technique similar to silent or staffless spellcasting?

However, compared to the former two, this unique technique provides a terrifying boost to strength, which explains why Professor Flitwick was able to defend his dueling championship for so many years with overwhelming force.

If I could learn it myself, some of the already incredibly powerful spells would probably become even more terrifying.

Even after Deep Blue's deduction, it might be possible to apply it to the Ancient Dragon form.

At that time, the power of the Triple Eternal Sun and the Triple Storm will far exceed imagination!

Just as Charles was pondering how to learn this skill from Professor Flitwick, Professor Flitwick said with a smile.

"I call this technique multicast."

"Want to learn?"

Charles nodded calmly.

"think."

The next moment, Professor Flitwick waved, signaling Charles to follow him into the Charms classroom.

"Come in. Since you don't need to attend my large lectures, I'll give you a private lesson."

Charles looked surprised; he hadn't expected Professor Flitwick to agree so easily.

Professor Flitwick, however, spoke with a smug look on his face.

"I am a professor at Hogwarts, and as a professor, it is only natural that I should impart all my knowledge to my students."

"Besides, Charles, you are the strongest genius I have ever seen. Your future achievements will far exceed my imagination."

"Multi-casting techniques, in my hands, have only resulted in a few duel championships, but in your hands, they might be refined to a higher level, accompanying you to greater achievements. Then wouldn't I also be remembered in history alongside you?"

A look of respect appeared on Charles's face as he bowed again to Professor Flitwick.

The phrase "giving one's all one's knowledge" sounds easy, but it's difficult to put into practice.

Throughout history, countless people have been unwilling to pass on skills developed with painstaking effort, and many unique spells have been lost to history in this way.

If it were Charles, how could he possibly teach the spells he painstakingly deduced to others?

Professor Flitwick's magnanimity is truly extraordinary.

At this moment, the other Hogwarts students standing nearby were also filled with envy.

They can't learn Char's talent, but if they could learn Professor Flitwick's multicasting technique, wouldn't that be awesome too?

Unfortunately, Professor Flitwick simply closed the door to the Charms classroom and gave them a warning.

"Don't try to eavesdrop. It's not that I'm biased and don't want to teach you; it's just that your foundation in spellcasting is too weak."

"Rashly learning overly advanced spellcasting techniques will not only be of no benefit to you, but will also cause you problems even in casting spells. Before thinking about flying, you should think about how to walk steadily."

"Of course, if any of you can create any new spell, I will give him the opportunity to learn multicasting from me."

Immediately, the classroom door closed, and Professor Flitwick cast a spell to prevent eavesdropping and peeping, much to the dismay of the Hogwarts students watching outside.

The curse of self-innovation?

Are you kidding me? How many Hogwarts students could create their own spells? They still have the self-awareness to admit it.

Seeing no hope of learning multiple spellcasting techniques, the students gathered there gradually dispersed.

Even after leaving the scene, everyone was still discussing the events that had just occurred with great interest, including Ciel's creation of his own spell and Professor Flitwick's admission that he was more talented than Dumbledore.

When they returned to the Academy Cup and saw that Hufflepuff had once again surpassed them by a large margin, reaching a total score of 400 points, they all looked on with awe.

"With Ciel like that, the Hufflepuffs should have already secured the Academy Cup this year."

But it wasn't just the Hufflepuff students who were happy about this; the Gryffindor and Ravenclaw students were also quite pleased.

After all, Slytherin had won the House Cup for the previous six years in a row.

If you say that Slytherin won in a very honorable way, everyone will accept it, at most admitting that they are not as skilled as others, and there will be no resentment.

The problem is that the biggest reason Slytherin won the House Cup was not because they were better, but because they had a protective and harsh head of the household.

Every time Potions class was held, Snape would drastically deduct points from other houses, giving Slytherin an opportunity to gain points.

Furthermore, if Snape catches you doing anything wrong, while other professors might just give you a warning or a lecture, Snape will immediately deduct points.

Other professors simply couldn't be so shameless, and the House Cup was naturally won by Slytherin House in the end.

But with the emergence of Ciel Evans this year, Hufflepuff is now leading by 400 points. How can Slytherin possibly turn the tide?

Not only did they not believe it, even the Slytherin students present were unsure.

Draco Malfoy, looking grim, rushed to Snape's office and reported the situation to him.

Upon hearing Malfoy's report, Snape's face showed surprise.

On the day of the commencement banquet, he did hear Professor McGonagall mention Charles Evans's talent for Transfiguration, and Dumbledore nodded in agreement.

But at the time, Snape didn't pay much attention to it.

But I never expected to hear this news today.

That little Hufflepuff wizard's talent in Transfiguration is more than just excellent; it's downright freakish!

There's also the study of spells. A first-grader, who hasn't even had a single class, can create two new spells on his own.

It's important to know that Ciel wasn't born a pure-blood nobleman, but rather a Muggle, so it was impossible for him to have the magic removed prematurely.

In other words, he really did accomplish this feat during the period between receiving the acceptance letter and the start of the semester.

Snape could only describe this little wizard as a prodigy.

However, upon hearing Malfoy express his concern about whether Slytherin could still win the House Cup this year, Snape's shock turned into indifference.

He said calmly.

"No one can take the House Cup from Slytherin."

Then, amidst Malfoy's surprised gaze, Snape said something in a calm tone.

"Draco Malfoy, with the honor of the House on his mind, Slytherin, ten points."

He glanced at the timetable and a mocking expression appeared on his face.

"Isn't Hufflepuff's Potions class coming up soon?"

"The Hufflepuffs are a bunch of idiots, even dumber than Gryffindors. The countless mistakes they've made are enough for me to give the Hufflepuffs a long time to settle."

"Don't worry, it won't be long before this gap is closed."

Hearing Snape's blatant protectiveness, even Malfoy felt sorry for Hufflepuff.

However, instead of feeling it was unfair, he was quite excited.

The only thing that still worries him a little is Ciel.

Shire's previous performance had truly shocked Malfoy.

"Godfather, what if Charles Evans isn't happy about this?"

Snape almost laughed in anger upon hearing this, looking at his godson with a mixture of disappointment and exasperation.

"If you asked Headmaster Sprout of Hufflepuff if Professor Sprout would be unhappy, I'd think you still had a brain. But Malfoy, what on earth are you thinking?"

"Charles Evans is unhappy? What can he do even if he's unhappy?"

"He's just a first-year student, and he thinks he can stand up to me, a professor and the head of Slytherin?"

Snape gave a dismissive sneer.

"Even graduating students wouldn't dare, let alone a novice wizard?"

"What if he really dares to have any objections..."

Snape's eyes revealed undisguised malice.

"I wouldn't mind teaching him what it means to respect a professor!"

……

Meanwhile, in the Conjuration classroom, Professor Flitwick was explaining the principles of multiple casting to Sharl.

"Echo, this unique technique utilizes a phenomenon I call echo."

"To understand the echo, one must understand the true nature of a wizard's spellcasting."

"Shahr, every wizard or magical creature has magic within them, but in most cases, the loss of magic power when we cast spells is negligible. The main loss is in our mental energy, and even the physical energy loss is greater than the loss of magic power."

"The power of a spell seems to be related to the magical power within us, but in reality it is determined by the intensity of the magical power and the strength of our spirit."

"The reason why some people say that the greater the magical power, the greater the spell power is is simply because the strength and total amount of a wizard's magical power are generally proportional, which creates this illusion."

"In fact, let alone wizards of Dumbledore's caliber, even newly enrolled wizards rarely run out of magic power, even after casting numerous spells. Why do you think that is?"

This question also prompted Charles to think deeply.

He had similar questions when he was reading the original Harry Potter books in his previous life.

The wizard's mana bar here is ridiculously long, it almost feels like it doesn't exist at all.

To become a wizard, one must possess magic.

However, after becoming a wizard, there is no sign that casting spells consumes magic power, which is quite strange.

Charles was surprised that Professor Flitwick would mention this phenomenon here, and he couldn't help but turn to look at Professor Flitwick.

The professor didn't intend to keep them in suspense and continued.

"Based on my personal understanding and after reading a lot of books on the principles of spellcasting, I believe that a wizard's spellcasting does not consume his own magic power, or rather, consumes very little of his own magic power. The source of spell power is almost entirely from the outside world."

"You can understand this external world as... the world, ether, the void, in short, it is everywhere."

"The reason why wizards must possess magic power to cast spells is that accessing external magic power requires certain qualifications, recognition, or status, and possessing magic power is necessary to possess this status."

"The strength of one's magic and mental strength determine the level of one's status and the amount of magic one can draw from the outside world. Spells and casting gestures are like commands, instructing the outside world to provide magic for the spell we are about to cast."

"The higher one's own magical power and mental strength, the more magical power one can draw upon when casting spells, making the same spell more powerful or releasing a stronger spell."

"Spellcasting without a staff or in silence will weaken the power of the spell because it reduces the accuracy of commands to the outside world and decreases the efficiency of the commands."

"As for the tiny amount of magic power we consume when casting spells, that's easy to understand. It's the cost of issuing the command, so it's naturally very small."

Upon hearing Professor Flitwick's explanation, a look of shock appeared on Charles's face.

He had most of his questions about wizards in the Harry Potter world answered through Professor Flitwick's explanation.

Even the dragon language magic of ancient dragons can be explained using this theory!

At the same time, Deep Blue also issued a series of notification sounds.

"Host has obtained high-grade magical materials..."

"The points required for the host to deduce all spells have decreased!"

This hint filled Charles with an uncontrollable surge of joy.

Unlike all the materials we've obtained before, this one is simply called High-Grade Magic Material, and its effect is that it works on all magic!

Instantly, the admiration in Charles's eyes for Professor Flitwick grew even stronger.

After giving me so much material on individual spells before, this is another big surprise. As expected of a professor of spells for so many years, his knowledge in this area is truly profound!

However, upon hearing this, Charles still had a question.

"Why is the outside world, or rather, the world, ether, and void you mentioned, filled with omnipresent magic?"

"Where does this magic come from?"

Professor Flitwick shook his head at this, revealing a look of longing.

"This is the ultimate question for scholars of Charms, and countless Charms masters have been exploring it tirelessly."

"Perhaps I will never find the answer to this question in my lifetime, but maybe you, Ciel, have the potential to do so."

Professor Flitwick then steered the conversation back to the technique of multiple spellcasting.

"I mentioned the feedback to you before, and now I can explain it clearly."

"When a wizard casts a spell, he uses incantations and hand gestures to send commands to the outside world. Just like shouting in a valley creates an echo or throwing a stone into water creates ripples, there is a similar magical resonance."

"Our command information is also preserved in the magical echo."

"Then, through magical resonance, it's naturally possible to command the outside world again to create the same spell once more..."

A look of understanding appeared in Charles's eyes.

Professor Flitwick chuckled.

"The principle is just that simple, it's actually quite straightforward."

"However, it is quite difficult to practice. It took me nearly ten years after I came up with this theory to successfully use the echo to repeat the first spell."

"Then it took almost twenty years to be able to repeat it once more and achieve triple casting."

"Charles, although you have high talent, I estimate that you'll be doing very well if you can complete dual casting by fifth grade, triple casting around twenty-five, and perhaps even quadruple or quintuple casting by forty!"

While excited about this, he also gave Charles a piece of advice.

"Remember, just as you need to concentrate more to discern the information in an echo, using magical echoes will also increase the mental strain, and the more times you repeat it, the greater the strain."

Ciel nodded seriously to show that he understood.

Professor Flitwick then waved for Charles to leave, telling him to come to him with any questions he might have.

Charles bowed respectfully to the universally acknowledged kind professor before leaving the classroom.

Charles kept in mind everything Professor Flitwick had just said.

However, a slight smile appeared on Charles's lips when he heard Professor Flitwick's estimate of how long it would take for him to master the multicasting technique.

"Maybe this is how normal geniuses are, but I'm a cheat code."

He found an empty classroom, locked the door, took a deep breath, and whispered in his mind.

"Deep Blue, demonstrate the multiple casting techniques for me!"

Sorry, I wasn't feeling well after recovering from COVID-19. I stayed up late updating a few chapters before and couldn't keep up, hence the late update. I'm almost fully recovered today, so I'll continue with the minimum 10,000-word update and some extra chapters.

Thank you for your support!
