Hogwarts: My Spell Infinite Derivation

Chapter 92 Triple Spellcasting! Some words, some things, come at a price!

With a whisper in Sharl's mind, Deep Blue directly deducted 150,000 deduction points and began the first deduction of Professor Flitwick's multiple spellcasting technique.

Charles was horrified.

The initial simulation alone required 150,000 points, which was among the highest of all the magical knowledge he had acquired.

And you should know that this was after he received a detailed explanation from Professor Flitwick, and even received a reduction in magic material points!

This shows just how high the potential of this multicasting technique is!

According to Deep Blue's assessment, its value may be comparable to the ancient dragon's dragon language magic system!

But Professor Flitwick imparted this precious knowledge to him without him having to pay anything in return.

Charles took a deep breath.

"I really owe this favor a huge debt."

"I need to find a chance to pay it back..."

Then, a stream of knowledge and experience about multiple spellcasting techniques began to flow through Sharl's mind.

The familiar feeling returned, as if countless parallel worlds contained countless versions of Ciel, simultaneously studying multiple spellcasting techniques day and night.

All the experience he had gained was poured into the instincts of this world's Charles body.

With the surge of knowledge and experience, Sharl seemed to see Deep Blue deduce the process of multiple spellcasting techniques.

According to Professor Flitwick, the first step is to capture the "echo" of the magic, that is, the "reverberation" produced after the spell is cast.

Professor Flitwick said it took him at least five years from developing the theory to capturing the response before he came up with a more feasible solution for capturing the response.

This time, in Deep Blue's deduction, Ciel started by capturing the echoes from the glowing spell he was most familiar with.

Between each second of deduction, countless fluorescent spells flashed, and countless attempts were made to capture the echo.

Professor Flitwick took five years to successfully capture the echo, but Charles accomplished it in an instant!

At that moment, he waved his wand and chanted a spell that glowed with light.

When the glow appeared, Ciel clearly felt a ripple of magic spreading through the space, producing magical "diffraction" and "interference" like water ripples.

During the initial diffusion, Ciel clearly sensed the enhanced portions of the magical interference, which were the [echoes] that Professor Flitwick had mentioned, containing complete information about the spell.

Echo capture complete!

However, the greater challenge lies in going from capturing echoes to using them for spellcasting.

Professor Flitwick spent fifteen of his first twenty years of research tackling this challenge.

With his talent and fairy blood, he would be more sensitive to magic than ordinary wizards.

It took a full fifteen years, which shows just how difficult it was.

And this only made Charles spend a moment more.

The next moment, a deep blue notification sounded in Xia Er's mind.

"The initial simulation of the multiple spellcasting technique has been completed. The host has acquired a special spellcasting skill—Spellcasting Echo."

"Capturing echoes and using them to cast spells has become an instinct for the host. The host can capture echoes and use them to cast spells at the fastest speed, and the power of the spells cast after an echo is almost completely reduced!"

This prompt made Charles's eyes light up.

According to Professor Flitwick, using echoes to cast spells results in a decrease in the power of the spell.

After all, although the echo theoretically contains the information needed for the formation of a spell, it is difficult to interpret it clearly in that fleeting moment.

That would be like a silent spell, so the command would be ambiguous, causing the spell to be cast correctly, but with less power than a normal cast. It's just that the reduction in power is not as drastic with multiple casts.

Moreover, theoretically, the more proficient one is at this technique, the less the power diminishes.

Charles had already anticipated this.

Even if the power is reduced to 70% of the original spell's power, he feels that casting spells multiple times in an instant is still a huge improvement.

But Xia Er didn't expect that through Deep Blue's deduction, he would directly accumulate this skill into his instinct, making the power reduction almost negligible.

Then this truly is an epic upgrade!

Ciel took a deep breath, waved his wand again, and released the glowing spell.

"Glowing Charm - Spell Resonance!"

Immediately afterwards, two glowing spells bloomed on Ciel's wand at the same time.

This can hardly be called fluorescence; it's more like a bright, high-powered light bulb!

Feeling the magic of the spell's echo, Charles took a deep breath; this was a huge boost to his strength.

Moreover, with this technique, a spell that might not have been able to penetrate an enemy's magical defenses could suddenly unleash a power powerful enough to pierce through them.

How could the enemy have imagined that the same spell could transform in an instant, doubling its power?

Without hesitation, Charles addressed Deep Blue once more.

"Deep Blue, continue the simulation."

In an instant, 1.5 million points were deducted, and Deep Blue began to deduce the direction of triple casting!

……

Meanwhile, in the dimly lit Potions classroom, a terrifying atmosphere was enveloping the young Hufflepuffs who came to class.

Dressed in a black robe, Snape's face was full of his usual harshness and arrogance, with a habitual smirk playing on his lips.

Just looking at it made the temperature in the classroom seem to drop a few degrees.

The little badger and the eaglets who came to class with him trembled and sat down one by one.

When the school bell rang, the cold atmosphere did not lessen at all; on the contrary, it intensified several times over.

Snape stared at an empty seat in Hufflepuff like a viper spotting its prey.

The young wizards in the classroom all had a strange feeling, as if they could hear a venomous snake hissing and flicking its tongue, revealing a sinister grin that seemed to be devouring its prey.

"Is one Hufflepuff missing?"

Snape's tone gradually rose.

"Ah, let me guess, it must be that famous genius—Charles Evans."

"Hehe, this has certainly broadened my horizons."

"I thought it would be another famous little wizard who would show such arrogance, but I didn't expect that the usually honest Hufflepuff would produce such an arrogant one."

Snape then let out a cold laugh.

"There are always some foolish wizards who think that because they are so talented at wielding wands, they can neglect potions lessons."

"They thought their talents in spells and transfiguration could be applied directly to potions."

"But I must say, this artful course is not like waving a magic wand haphazardly."

"I don't expect you Hufflepuffs, who are known for your dullness, to truly appreciate the beauty of a slow-cooking pot simmering over a low flame, emitting white smoke and fragrant aromas."

"You will never truly understand the wondrous power of the fluid that flows into people's veins, the power that captivates the mind and confuses the will..."

"You've always been the same idiots and fools I encounter. I just want to get rid of you quickly, graduate as soon as possible, and never show your faces in my classroom again."

"Ah, so this genius Charles Evans beat me to it and didn't even come to Potions class? I don't remember approving his exemption application."

Then, Snape announced something that chilled the Hufflepuffs to the bone.

"Hufflepuff loses 100 points for Charles Evans's absence, and for the arrogance and disrespect for the professor that his behavior reveals."

The next moment, the little Hufflepuffs couldn't help but stir.

They had already heard from their seniors about the punishments for being late or skipping class.

Being late was quite common at the beginning of the first semester, since the young wizards were not familiar with the castle's layout, and the professors were tolerant of it.

Even if you are twenty minutes late, the professor will at most give you a reminder; it won't result in a deduction of points.

Of course, if it comes to skipping class, some strict professors will definitely deduct points.

However, the first absence is usually only for about ten minutes, and some professors are even more lenient and just give a verbal warning.

Who else would deduct a hundred points right from the start like Snape?

That wasn't all; Snape continued to spew venom from his mouth.

"Does Charles Evans think he's something special?"

"Let me tell you, I've seen plenty of geniuses. What are geniuses anyway? Many geniuses fade into obscurity, and many geniuses die because of their foolish, reckless, and arrogant actions, sometimes even taking others with them."

"In my opinion, Charles Evans is very likely one of those so-called geniuses who died from arrogance."

"I have a suggestion for you: stay away from this kind of person, unless you want to die a miserable death alongside him!"

Hannah Abbott, the shy girl at the Sorting Ceremony, had helped old Tom deliver meals to the Shire a few times at the Leaky Cauldron.

When she heard Snape assert that Shire would most likely die a horrible death, she could no longer hold back and stood up.

"Professor, Charles won't die!"

"He's not an arrogant person at all; he's a really nice guy..."

Before he could finish speaking, Snape revealed a cold smile.

"Yeah?"

"Hannah Abbott, before you defend Charles Evans, did you raise your hand? Did you get my permission to stand up?"

"Hufflepuff deducts another 10 points for violating classroom discipline."

Another Hufflepuff girl couldn't resist raising her hand.

After Snape nodded with a cold smile, signaling her to stand up, Susan Bornes said something.

"Professor, there's a reason why Charles didn't come to class. He must have been exhausted from two exams. Besides, the bell just rang, so it's only late, not an absence..."

Before she could finish speaking, she was forced to sit down again by Snape's stern gaze.

Snape's sneer deepened.

"shirk."

"Making an excuse."

"quibble!"

"And when did Hufflepuff start trying to be clever and exploit the rules?"

"Hufflepuff deducts another twenty points!"

Snape's malice towards Hufflepuff is now quite obvious.

After Susan Bornes sat down, pale-faced, the badgers all lowered their heads, fearfully avoiding Snape's gaze.

Snape seemed satisfied then, and said quietly.

"Alright, now that you've finally learned your lesson, we can finally begin today's lesson."

"I'm really looking forward to seeing how you do in your first class."

The little badger and the eaglets beside him breathed a slight sigh of relief.

Snape will surely be quieter if he attends class, right?

But the next moment, instead of starting the formal lesson, Snape launched into a barrage of questions from Hufflepuff, asking them about things that were clearly going to be covered in later lessons.

This isn't even in front of the textbook. Even for Ravenclaws who normally have the habit of previewing, at least 70-80% wouldn't have seen this part, let alone Hufflepuff, who isn't known for their intelligence.

Under Snape's questioning, they were naturally wiped out.

Snape's expression was icy.

"So you guys aren't focusing on your studies?"

"Didn't you do any preparation?"

"You think you're here for sightseeing and entertainment at Hogwarts?"

"Points deducted, points deducted, points deducted!"

In the blink of an eye, just from this Q&A session alone, Snape had deducted another thirty points from Hufflepuff.

During this time, the venom he spat out caused the badger cubs to lower their heads, some with blood-red faces and others with pale expressions.

The badgers who were called upon to answer the questions all fell into a daze.

Even so, Snape seemed to have been turned on by some switch, and the venom he spewed from his mouth never stopped throughout the entire class.

He spent the entire class hovering around the badger cubs.

The moment a mistake is discovered, a torrent of ridicule, sarcasm, and even insults ensues.

"Pig!"

"What's wrong with your head?"

"Is it because the apple pie you ate last night hasn't digested yet?"

"I meant cutting porcupine quills into three-centimeter segments, what did you cut? Are you trying to mince porcupine?"

"And you, did you even get the stirring order right? Which is left, which is right, which is clockwise, and which is clockwise?"

Answer my question!

"You think you can hide this pot of garbage by keeping your head down? Can't you see clearly? Can't you smell it? Why don't you dump this whole pot of garbage you produced?!"

The little Hufflepuffs lowered their heads one by one; this Potions class had become a nightmare for them.

The girls all had red eyes and were crying, and even the little boy who had been taught to be strong was half-crying.

Many young wizards have fallen into a daze and dare not touch potion ingredients at all.

Not to mention the Ravenclaws trembling on the sidelines, even Snape himself felt that he might have gone a bit too far by the end.

But should we make him bow his head?

Absolutely impossible!

Just then, the bell rang, signaling the end of get out of class, and Snape gave a cold snort.

"get out of class dismissed."

……

In the empty classroom, Deep Blue's voice echoed in Charles's mind.

"The second derivation of the multiple spellcasting technique is complete. The host has acquired a special spellcasting technique—triple spellcasting."

At that moment, a look of joy appeared in Charles's eyes.

This is comparable to Professor Flitwick's level; he can instantly unleash three identical spells!

Unfortunately, further deduction would require too many points, which Charles could afford, but he still didn't want to use them rashly.

The triple casting technique, which can be described as a divine skill, is more than enough for him at the moment.

An eager look appeared on his face, as he wanted to test the power of triple casting.

This time, Ciel wasn't content with just experimenting with the Glowing Charm.

He raised his hand.

"Flash of Light - Triple Cast!"

The next moment, a light far more dazzling than when they fought Professor Flitwick erupted.

The light was so intense that even wearing sunglasses wouldn't help.

Even if you create a dark area with magic, it might be forcibly pierced by the dazzling light! Then, Charles tried the laser spell.

The triple-cast laser spell can instantly unleash three laser beams, one horizontal and one vertical, greatly restricting the enemy's escape space.

To create the laser net that Char used before, triple casting would be much faster.

However, these spells have almost been phased out by Xia's current combat system. They were only used previously to avoid revealing too much of his strength.

The only combat methods that Sharl can actually use most often, besides those high-powered spells, are Night's Edge and the Night Blade spell, which he can try out here.

"Night's Edge - Triple Cast!"

As the incantation was uttered, an invisible sharpness suddenly shot out from the tip of Ciel's mithril wand.

Originally, after his spiritual transformation, the invisible light blade of the Night's Edge Spell that Sharl activated could be about two meters long.

Now, after being cast three times, the length of this light blade has reached an absurd six meters.

And because of its extremely fast activation speed, it almost instantly crossed the length of the classroom and pierced into the wall at the other end!

Charles's eyes widened.

Whether it's the speed of attack or the range, it's an instantaneous surge, a qualitative leap.

Enemies that Charle used to have to get close to can now be pierced through by invisible light blades at mid-range!

If a sufficiently strong magical defense isn't set up beforehand, probably few wizards would be able to react to this attack.

Charles took a deep breath, his heart pounding.

"Awesome!"

With the Night's Edge Spell undergoing such a qualitative change, he couldn't wait to find a place to test whether he could handle the powerful spells like Eternal Blazing Sun, Sun Without Light, Holy Kingdom, and Sovereign God under multiple spellcasting.

He even wanted to try it out and see if he could use this technique in his Ancient Dragon form!

"The Forbidden Forest has enough space, but the House of Requirement is still more convenient."

Charles stepped out of the classroom, intending to go to the Room of Requirement to test the performance of these powerful spells under multiple casting.

Before entering the corridor, he cast an illusion spell on himself.

After all, he had become famous at Hogwarts today, and he didn't want people to pay attention to his actions.

As Ciel walked down the corridor, trying to figure out where the Room of Requirement was, suddenly, the crying Hufflepuffs came from the front, as if a dark cloud was hanging over them.

A hint of surprise flashed in Charles's eyes. He wondered what had happened to them and why they were crying so bitterly.

He didn't intend to get involved in these matters, since he really disliked being a nanny and even more so, he disliked children.

It's too noisy.

Besides, whatever setbacks the badger cubs encounter, it's all part of their growth.

Some setbacks are inevitable. Only children from privileged backgrounds are pampered and spoiled. Ordinary people will inevitably face the harsh realities of society sooner or later.

The setbacks you face at school may seem insurmountable while you're in school, but after graduation, you realize they're nothing.

But it is perhaps through experiencing setbacks at school that one can gradually adapt to failures and frustrations after graduation.

Ciel didn't want to interfere with the children's normal development and was already planning to leave, until he heard the sullen little Ravenclaws complaining to the badger cubs.

"Professor Snape is deliberately targeting us."

"When Ciel missed class, he was already furious and deducted a hundred points. You shouldn't have defended Ciel in that anger. You could have just gone along with Professor Snape, or at least kept your heads down and said nothing."

"Look what he said about you afterwards! It was downright insulting, a personal attack!"

"Hufflepuff lost more than half their marks in this lesson. Was it worth it?"

Hannah Abbott retorted, her face flushed.

"No, Ciel gave Hufflepuff so many points, he's a hero to us."

"Besides, the points belong to Sharga, so even if half are deducted, it's still a lot of points."

"We Hufflepuffs are loyal to our friends and classmates, and we won't just say whatever comes to mind for fear of being scolded or losing points."

The Ravenclaw hawks shook their heads, clearly disapproving of this approach.

Just then, Hannah and the little badgers heard Charles's voice.

Charles looked at Hannah and asked a question.

"Hannah, did Professor Snape scold you?"

"Tell me what Snape said about you."

Hannah and the others blushed and shook their heads, tears welling up in their eyes.

Charles gazed at Hannah.

"Tell me, it's okay, I can handle it."

Hannah's eyes suddenly reddened even more, tears streaming down her face as she sobbed and repeated Snape's words.

Charles listened quietly, his expression growing increasingly somber and cold.

To be honest, Ciel wasn't annoyed when Snape first mentioned himself.

I did skip class and break the rules, so Snape can say whatever he wants.

He really couldn't be bothered to argue with Snape over this. At most, when he was calculating Snape's potion ingredients, he would choose not to leave him a single penny, or when he robbed Snape in the dead of night, he would break a few of his bones as well.

As for the points deducted, Charles didn't care at all.

We're adults now. We can add points or deduct points as we please. Who cares about these "little red flowers from kindergarten"?

He added 400 points to Hufflepuff, and no one can argue with him about losing those 400 points.

Ciel wasn't angry about these things.

What angered Ciel was that Snape had implicated those who spoke up for him and defended him.

What he found even more intolerable was that Snape, not content with what he had done, continued to attack the badgers with vicious words, destroying their dignity.

What kind of person would do something like this?

Charles stopped in his tracks, his eyes now as cold as ice.

He doesn't care about many things. After all, he's an adult who's struggled in his previous life. He hasn't made much money, but his moral bottom line and sense of responsibility have plummeted.

But after what happened today, Xia Er felt that if he didn't do something, he might as well use the tens of millions of points he spent on the deduction to feed the turtles.

He stopped in his tracks, heading towards the Room of Requirement, and looked at Hannah and the badgers.

"Send a few of you to Professor Sprout and report to her exactly what Snape said to you today."

"Others went to Professor Flitwick, the dean of Ravenclaw, who was also present."

"Then go find Professor McGonagall, the Vice-Headmaster, and Professor Dumbledore, the Headmaster of Hogwarts, and tell them exactly how Snape insulted you."

Charles's voice softened a little.

"If anything happens, trust our own professors and deans. Don't just swallow your anger and suffer in silence, understand?"

Then, Charles turned around.

Hannah asked him from behind.

"And what about you, Ciel?"

Charles turned around and forced a sinister smile.

"Since some people lack manners and don't know how to learn from their mistakes, I'll teach them a lesson and help them remember something—"

"Some words spoken and some deeds done come at a price."
