As Charle heard the whispers in his mind, Deep Blue directly deducted 150,000 deduction points and began the initial deduction of Professor Flitwick's Multiple Casting Technique.
Charle's heart was filled with shock.
Just the initial deduction required 150,000 points, which was among the highest of all the magical knowledge he had acquired.
And one had to remember, this was after he had received a detailed explanation from Professor Flitwick and even obtained a reduction in points for magical materials!
This showed how high the upper limit of this Multiple Casting Technique was!
According to the Deep Blue system's evaluation, its value might be comparable to the Ancient Dragon's Dragon Language Magic System!
But such precious knowledge was taught to him by Professor Flitwick without him having to pay anything.
Charle took a deep breath.
"This favor is truly a huge one."
"I need to find an opportunity to repay it..."
Then, waves of knowledge and experience regarding the Multiple Casting Technique began to flow into Charle's mind.
The familiar feeling reappeared, as if countless Charle in countless parallel worlds were simultaneously studying the Multiple Casting Technique day and night.
All the summarized experience was poured into the instincts of this world's Charle.
Along with the surge of knowledge and experience, Charle seemed to see the process of Deep Blue deducing the Multiple Casting Technique.
According to Professor Flitwick, the first step was to capture the magic's Spell Echo, which was the "echo" produced after casting a spell.
Professor Flitwick said that it took him at least five years from developing the theory to capturing the echo, and only then did he summarize a more feasible plan for capturing the echo.
This time, in Deep Blue's deduction, Charle started capturing the echo from the Lumos spell, which he was most familiar with.
In every second of deduction, the Lumos spell flashed countless times, and countless attempts were made to capture the echo.
Professor Flitwick took five years to successfully capture the echo, but Charle succeeded in an instant!
At this moment, he waved his wand and chanted the spell for Lumos.
When the light lit up, Charle also clearly felt a ripple of magic spreading in space, producing magical "diffraction," "interference," and so on, like water waves.
In the initial diffusion, Charle clearly felt the enhanced parts of those magical interferences, which were the *Spell Echoes* carrying complete spell information mentioned by Professor Flitwick.
The echo capture was complete!
However, from capturing the echo to using the echo to cast spells was an even greater hurdle.
Fifteen of the first twenty years of Professor Flitwick's research were spent on tackling this aspect.
With his talent, coupled with his goblin bloodline, he would be more sensitive to magic than ordinary wizards.
But it still took a full fifteen years, which showed how difficult it was.
And this only made Charle spend an extra instant.
The next moment, Deep Blue's prompt sounded in Charle's mind.
Multiple Casting Technique initial deduction completed. Host has gained a special casting technique - Spell Echo.
Capturing the echo and using it to cast spells again has become the host's instinct. The host can capture the echo and use it to cast spells at the fastest speed, and the power of the spell after the echo has almost no attenuation!
This prompt made Charle's eyes light up.
According to Professor Flitwick, there was a decay in spell power when using the echo to cast spells.
After all, although the echo theoretically also contained the information needed to form a spell, it was difficult to interpret it so clearly in that fleeting instant.
Then it would be like a silent spell, resulting in vague commands, causing the spell to be cast correctly but with reduced power compared to a normal cast, only the reduction in Multiple Casting was not so exaggerated.
And theoretically, the more proficient this technique was, the lower the power decay would be.
Charle had already had a psychological expectation for this.
Even if it was reduced to 70% of the original spell power, he felt that casting multiple spells instantly was a huge improvement.
But Charle did not expect that through Deep Blue's deduction, this technique would be directly accumulated into his instinct, making the power decay almost negligible.
Then this was truly an epic improvement!
Charle took a deep breath, waved his wand again, and cast the Lumos spell.
"Lumos - Spell Echo!"
Immediately after, two Lumos spells bloomed from Charle's wand at the same time.
This could not be called Lumos, but rather a bright, high-power light bulb!
Feeling the magic of the Spell Echo, Charle took a deep breath. This was a huge improvement in strength.
Moreover, with this technique, a spell that might not have been able to overcome the enemy's magical defense the previous moment might burst out with enough power to pierce it the next moment.
How could the enemy have thought that the same spell could instantly transform and double its power?
So Charle, in the next moment, without any hesitation, said to Deep Blue again.
"Deep Blue, continue the deduction."
Instantly, 1.5 million points were deducted, and Deep Blue deduced towards Triple Casting!
...
Meanwhile, in the gloomy Potions classroom, an atmosphere that could only be described as terrifying enveloped the young Hufflepuffs who had come for class.
Snape, clad in black robes, wore his usual expression of harshness and arrogance, a habitual sneer playing on his lips.
Just his appearance seemed to lower the temperature in the classroom by several degrees.
The little badgers and the little eagles who had come for class with them shivered, sitting down one after another.
When the class bell rang, this icy atmosphere not only didn't diminish in the slightest but instantly intensified several times over.
Snape looked at an empty seat among the Hufflepuffs, like a venomous snake spotting its prey.
The young wizards in the classroom had the illusion that they could hear the snake hissing and flicking its tongue, revealing a sinister grin as if ready to devour someone.
"A Hufflepuff didn't show up?"
Snape's tone gradually rose.
"Ah, let me guess, it must be that famous genius—Charle Evans."
"Heh, that's quite an eye-opener."
"I thought it would be another famous young wizard who would show such arrogance, but I didn't expect such an arrogant person to come from the usually honest Hufflepuff."
Snape then let out a cold laugh.
"There are always some foolish wizards who think that because they have some talent in waving a wand, they can disregard Potions class."
"They think that their talent in Charms and Transfiguration can be directly applied to Potions."
"But I must say, this artistic subject is not like foolishly waving a wand."
"I don't expect you Hufflepuffs, known for your dullness, to truly appreciate the beauty of a cauldron simmering over a low flame, emitting white smoke and a fragrant aroma."
"You will never truly understand the wondrous magic of the liquid that flows into people's veins, captivating the heart and confusing the will..."
"You are always the same kind of stupid fools I often encounter. I only wish to get rid of you quickly, let you graduate early, and never appear in my class again."
"Ah, and as a result, Charle Evans, this genius, has taken the lead and isn't even coming to Potions class? I don't recall approving his request for exemption."
Then, Snape announced something that made the young Hufflepuffs' blood run cold.
"Hufflepuff loses one hundred points, for Charle Evans's absence, and for the arrogance and disrespect towards a professor revealed by his actions."
The next moment, the young Hufflepuffs couldn't help but stir.
They had already heard from their seniors about the punishments for being late or absent.
Being late was quite common at the beginning of the first term, as the young wizards were unfamiliar with the castle's layout, and the professors were tolerant of this.
Even if they were twenty minutes late, the professor would at most give a reminder, not deduct points.
Of course, if it reached the point of absence, some strict professors would definitely deduct points.
But the first absence usually only resulted in about ten points being deducted, and some more lenient professors would only give a verbal warning.
How could anyone like Snape deduct a hundred points right away?
Not only that, but Snape's mouth continued to spew venom.
"Charle Evans thinks he's something special?"
"I tell you, I've seen plenty of geniuses. What are geniuses? Many geniuses fade into obscurity halfway through, and many geniuses die because of their foolish, reckless, and arrogant actions, even taking others with them."
"In my opinion, Charle Evans is very likely to be that kind of so-called genius who dies from arrogance."
"I'll give you a piece of advice: stay away from such people if you don't want to die a miserable death with him!"
Hannah Abbott, the shy girl from the Sorting Ceremony, had helped Old Tom deliver meals to Charle several times at the Leaky Cauldron.
Hearing Snape assert that Charle would likely die a miserable death, she couldn't hold back any longer and stood up, saying.
"Professor, Charle won't die!"
"He's not arrogant either, he's a very good person..."
Before she could finish, Snape revealed a cold sneer.
"Is that so?"
"Hannah Abbott, before you defend Charle Evans, did you raise your hand? Did you stand up and get my permission?"
"Violating classroom discipline, Hufflepuff loses another ten points."
Another Hufflepuff girl couldn't help but raise her hand.
After Snape nodded with a cold smile, indicating for her to stand up, Susan Bones said.
"Professor, there's a reason Charle didn't come to class. He must be too tired after two exams, and besides, the class bell just rang, so it's only being late, not absent yet..."
Before she could finish, she was forced to sit down by Snape's stern gaze.
Snape's cold sneer intensified.
"Excuses."
"Making excuses."
"Quibbling!"
"Also, since when did Hufflepuff start playing smart and trying to exploit the rules?"
"Hufflepuff loses another twenty points!"
Snape's malice towards Hufflepuff was already clear for all to see.
After Susan Bones sat down with a pale face, the little badgers all lowered their heads, fearfully avoiding Snape's gaze.
Only then did Snape seem satisfied, and he said in a low voice.
"Alright, since you've finally learned your lesson, we can finally begin today's class."
"I'm really looking forward to your performance in the first class."
The little badgers and the little eagles beside them breathed a slight sigh of relief.
If it was class time, surely Snape would calm down, right?
But the next moment, Snape didn't start the formal content of the class. Instead, he called out names in Hufflepuff like a machine gun, asking them about content that was clearly in later lessons.
This wasn't in the front of the textbook at all. Even the Ravenclaws who normally had the habit of previewing hadn't seen this far, at least seventy to eighty percent of them, let alone the Hufflepuffs who weren't known for their intelligence?
Under Snape's questioning, they were naturally completely defeated.
Snape's expression was cold.
"So your brains aren't focused on studying, are they?"
"No previewing?"
"Do you think you're here at Hogwarts for sightseeing and entertainment?"
"Points off, points off, points off!"
In the blink of an eye, just from this questioning session, Snape deducted another thirty points from Hufflepuff.
The venom he spewed during this time made the little badgers lower their heads even further. Some had bright red faces, while others were deathly pale.
The little badgers who were called up to answer questions all fell into a daze without exception.
Even so, Snape seemed to have flipped a switch, and the venom he spewed didn't stop for the entire class.
He patrolled around the little badgers for the entire class.
As soon as he found a small mistake, it was immediately a storm of ridicule, sarcasm, and even outright insults.
"Pigs!"
"What's in your brain?"
"Did you not digest the apple pie you ate last night?"
"I said cut the porcupine quills into three-centimeter sections. What did you cut? Are you trying to cut porcupine dust?"
"And you, did you figure out the stirring order? Which is left and which is right, which is clockwise and which is clockwise?"
"Answer my question!"
"You, do you think lowering your head can hide this pot of garbage? Can't your eyes see clearly? Can't your nose smell the scent? Why aren't you pouring out this pot of garbage you produced?!"
The little Hufflepuffs lowered their heads one after another. This Potions class had become their nightmare.
The girls all had red eyes and were crying, and even the little boys who had been taught to be strong were half crying.
Many little wizards had fallen into a daze and didn't dare to touch the potion ingredients at all.
Not to mention the trembling Ravenclaws beside them, even Snape himself felt like he had gone a bit too far by the end of his rant.
But for him to back down?
Absolutely impossible!
Just then, the class bell rang, and Snape snorted coldly.
"Class dismissed."
...
In the empty classroom, Charle heard Deep Blue's voice in his mind.
"Multiple Casting Technique secondary deduction complete. Host has obtained special casting technique - Triple Casting."
At this moment, Charle's eyes showed joy.
This was already comparable to Professor Flitwick's level, capable of instantly casting three identical spells!
It was a pity that further deduction required too many points. Although Charle could afford it, he still didn't want to use them so rashly.
A technique like Triple Casting, which could be called a divine skill, was already enough for him at the moment.
An eager expression appeared on his face, wanting to test the power of Triple Casting.
This time, Charle was not satisfied with testing it on the Lumos spell.
He raised a hand.
"Flash Spell - Triple Casting!"
The next moment, a light far more dazzling than when he fought Professor Flitwick erupted.
The light was so intense that even wearing sunglasses would likely be useless.
Even creating a dark area with magic might be forcibly pierced by the blinding light! Then, Charle tried the Laser Spell again.
Under Triple Casting, the Laser Spell could instantly unleash three lasers crisscrossing horizontally and vertically, greatly restricting the enemy's dodging space.
To form the laser net Charle had used before, it would also be much faster through Triple Casting.
However, these few spells were almost eliminated from Charle's current combat system; he only used them before to avoid exposing overly exaggerated strength.
The combat methods Charle currently used frequently, besides those high-power spells, were only the Night's Edge spell, which he could try here.
"Night's Edge—Triple Casting!"
As the incantation was spoken, an invisible sharp edge suddenly shot out from the tip of Charle's mithril wand.
Originally, after his mental transformation, the invisible light blade of the Night's Edge spell Charle unleashed could reach a length of about two meters.
Now, after Triple Casting, the length of this light blade reached an outrageous six meters.
And because the activation speed was extremely fast, it almost instantly crossed the length of the classroom and pierced into the wall on the other side!
Charle's eyes widened.
Both the killing speed and distance instantly surged, a qualitative leap in improvement.
Originally, Charle needed to be close to the enemy, but now at medium range, they would be directly pierced by the invisible light blade!
If sufficient magical protection wasn't set up in advance, probably few wizards could react to this attack.
Charle took a deep breath, his heart pounding.
"Awesome!"
Since the Night's Edge spell had such a qualitative change, he couldn't wait to find a place to try whether he could handle high-power spells like Eternal Blazing Sun, Sun of No Light, Sacred Land, and Only I Am The Honored God under Multiple Casting.
He even wanted to try if he could use this technique in his Ancient Dragon form!
"The Forbidden Forest has enough space, but the Room of Requirement is more convenient."
Charle stepped out of the classroom, planning to go to the Room of Requirement to test the performance of these high-power spells under Multiple Casting.
Before entering the corridor, he cast a Disillusionment Charm on himself.
After all, he had become famous at Hogwarts today, and he didn't want people to pay attention to his actions.
Walking along the corridor, as Charle was thinking about the location of the Room of Requirement, suddenly, crying little Hufflepuffs came from the front, as if a dark cloud was hanging over them.
A hint of surprise appeared in Charle's eyes. He didn't know what they had encountered to be crying so miserably.
He didn't plan to get involved in these matters. After all, he really didn't like being a babysitter, and he disliked children even more.
They were too noisy.
Besides, no matter what setback the little badgers encountered, it was a part of growth.
Some setbacks were just meant to be endured. Only children from high-status families would be pampered everywhere; ordinary people would be battered by society sooner or later.
Setbacks in school, which seemed like the end of the world while studying, turned out to be nothing after graduation.
But perhaps it was by enduring some setbacks in school that one could gradually adapt to failure and frustration after graduation.
Charle didn't want to interfere with the normal growth of children. He had already decided to leave until he heard the disgruntled little Ravenclaws next to them complaining to the little badgers.
"Professor Snape is simply deliberately targeting us."
"When Charle didn't come to class, he was already furious and directly deducted a hundred points. You shouldn't have defended Charle when he was angry. Just go along with what Professor Snape says, or at worst, just lower your head and don't say anything."
"Look at what he said about you later, that was simply humiliation, it was a personal attack!"
"In this class, Hufflepuff's points were deducted by more than half. Was it worth it?"
Hannah Abbott's face turned red as she retorted.
"No, Charle added so many points to Hufflepuff, he is our hero."
"Besides, the points were added by Charle, even if half were deducted, that's still a lot of points."
"We Hufflepuffs are loyal to our friends and classmates, we won't just go along with what's said because we're afraid of being scolded or losing points."
The little eagles of Ravenclaw shook their heads, clearly disagreeing with this approach.
Just then, Charle's voice suddenly reached the ears of Hannah and the little badgers.
Charle looked at Hannah and asked.
"Little Hannah, were you scolded by Professor Snape?"
"Tell me, what did Snape say about you?"
Hannah and the others' faces turned red and they shook their heads, but tears were already welling up in their eyes.
Charle looked at Hannah.
"Tell me, it's okay, I can handle it."
Hannah's eyes instantly turned even redder, tears streamed down, and she sobbed as she repeated what Snape had said.
Charle listened quietly, his expression growing increasingly somber and cold.
To be honest, Charle wasn't annoyed when Snape first started talking about him.
He hadn't attended class, which was a violation of the rules, so Snape could say what he wanted.
He was too lazy to argue with Snape over this. At most, when he was calculating Snape's potion ingredients, he would make sure not to leave a single scrap for him, or perhaps break a few of his bones when he robbed Snape on a dark and stormy night.
As for losing points, Charle cared even less.
He was an adult; if they wanted to add points, they could add them, and if they wanted to deduct them, they could deduct them. Who cared about these "kindergarten gold stars"?
He had earned Hufflepuff four hundred points; even if all four hundred were deducted, no one could complain to him.
Charle wasn't angry about any of this.
But what made Charle angry was that Snape had implicated the people who had spoken up for him and defended him.
What he found even more intolerable was that Snape still wasn't satisfied and continued to attack the little badgers with vicious words afterward, crushing their dignity.
What kind of person would do such a thing?
Charle stopped walking, his eyes as cold as ice.
He didn't care about many things; after all, he was an adult who had struggled in his previous life. He hadn't made much money, but his moral bottom line and sense of responsibility had long since plummeted.
But today, Charle felt that if he didn't do something, the tens of millions of points he had spent on deductions might as well be fed to turtles.
He stopped his plan to go to the Room of Requirement and looked at Hannah and the little badgers.
"A few of you go find Professor Sprout and report everything Snape said to you today, word for word."
"The others go find Professor Flitwick, the head of Ravenclaw, who was also present."
"Then go find Deputy Headmistress Professor McGonagall, and go find the Headmaster of Hogwarts, Dumbledore, and tell them exactly how Snape insulted you."
Charle's voice softened slightly.
"If something happens, you must trust our own professors and heads of house. Don't just endure it silently, understand?"
Then, Charle turned his body.
Hannah asked behind him.
"What about you, Charle?"
Charle turned back and forced a chilling smile.
"Since some people have no manners and don't know how to learn from their mistakes, I'll go teach him a lesson and make him remember one thing clearly—"
"Some words spoken, some things done, come with a price."
