Hogwarts: My Spell Infinite Derivation

Chapter 114 The Death-Taking Curse: Lightning Chain, One Curse Clears the Screen!

However, while looking forward to it, Ciel also thought about the weaknesses of the Killing Curse.

Although the Killing Curse in the original work is very powerful, in the hands of a wizard who can unleash its power, it is almost certain to kill, and almost no protective magic can be effective against it.

However, its drawbacks are also obvious: it lacks locking and area-of-effect damage, offering only extreme single-point lethality.

This resulted in the fact that, in many of the major battles in the original work, the number of people killed by the Killing Curse was actually not that many, despite the constant movement.

It was only in the hands of Voldemort, the wizard who knew the Killing Curse best in the magical world, that the Killing Curse became truly a "finger of death," killing wherever it touched.

But that only applies to wizards of a much lower rank than him. In the original story, when Voldemort fought Dumbledore at the Ministry of Magic, the Killing Curse, which was said to be a sure-kill spell, was completely useless. Instead, he made extensive use of Transfiguration to fight against Dumbledore.

This is actually a manifestation of the Killing Curse's weakness.

At this level, the pace of combat is incredibly fast, and they make extensive use of apparition. Their reaction speed is also astonishingly fast due to their powerful mental strength.

Avoiding the green light of the Killing Curse is not difficult at all unless one is restricted by other spells.

As for the shortcomings of the Killing Curse, everyone understands them, and it's not like no one wants to improve it.

But the Killing Curse is an extremely sophisticated curse, and it's not easy to improve it.

Even Voldemort himself, after so many years, has not been able to create a more advanced Killing Curse; at most, he has made some minor improvements that only he could implement.

But for Ciel, with the existence of Deep Blue, even the Killing Curse can be deduced and improved, making up for all these shortcomings!

However, Ciel did not rush to deduce the Killing Curse, but instead planned to deduce the other dark magic first.

After all, in the process of deducing other black magic, new knowledge will be acquired, which may be used in the deduction of the Killing Curse later.

Anyway, after obtaining the Cerberus transformation, the first three deductions of all dark magic did not consume any points, which was more than enough for him to become a top master in the field of dark magic!

A light shone in Charles's eyes.

"Deep Blue".

"Soul-Stealing Curse, Heart-Piercing Curse, Divine Sharpness Curse, Fiery Curse..."

"All the dark magic I acquired has been deduced three times!"

As Charles whispered, in the next moment, his mind was flooded with seemingly endless knowledge of dark magic.

Torture, manipulation, dismemberment, incineration...

Various strong malices arose, but they had no effect whatsoever before Charles's brain closure surgery.

A look of understanding appeared on Charles's face.

After coming into contact with dark magic, he understood why it was called "dark magic".

Unlike white magic, which requires positive emotions, black magic requires strong malice in people's hearts.

It requires the caster to have a strong desire to torture, kill, burn, or manipulate others like puppets.

Compared to positive emotions such as protection, beauty, and kindness, such evil thoughts are clearer and stronger.

This leads to a situation where, among wizards of equal magical and mental strength, one uses white magic and the other uses black magic, the spells cast by the wizard using black magic are often far more powerful.

However, casting dark magic comes at a price: one's mind will gradually become distorted.

Just like murder, as friends who frequently commit murder know, the first time is the hardest; it's very difficult to take that first step.

But once you take that first step, the second and third times will become easier and easier.

Using the Killing Curse, even without killing anyone, is equivalent to releasing an extremely strong killing intent in one's mind, which is far more impactful than killing three or five people.

Using it once or twice might not be a problem, but long-term use of such dark magic will inevitably lead to mental corruption.

Indiscriminate killing and a penchant for torture are the inevitable consequences of using the Killing Curse and the Heart-Rending Curse.

Other forms of black magic can also lead to mental distortion, so most wizards who are immersed in black magic are extremely vicious.

Charles also felt a strong mental shock at this moment. Although his Occlumency spell could shield him from these effects, no one could guarantee that Occlumency spell could completely isolate all effects under the long-term impact of dark magic.

Just look at Voldemort. When Voldemort first appeared, the Death Eaters were just a political party, not particularly extreme.

However, as time went on, the behavior of the core members, including Voldemort himself, became increasingly extreme, to the point that the Death Eaters' reputation is now completely ruined.

Therefore, Ciel immediately specified the direction of the first two deductions of these dark magic spells.

"First, enhance the stability of the spell. Just like deriving the Guardian Charm, I don't need the kind of spell that can't be used without a specific emotion."

"Secondly, to remove the mental impact of black magic, I don't need such spells that affect me."

"A spell is just a tool; how can anyone be changed by a tool? So, does the person control the spell, or does the spell control the person?"

After a moment of contemplation, Charles specified the direction for the third deduction.

"Finally, let me push this to an even more extreme direction."

"I feel that the effects of dark magic in the magical world are still too mild, especially the Unforgivable Curse. Is that really unforgivable?"

"The Imperishable Curse can be resisted, and the control time is not long, with no aftereffects. It's a bit of a stretch to call it the Unforgivable Curse."

"Give me the Mirror of Reincarnation, which I've derived from Legilimency, to enhance the effects of the Imperius Curse, and simultaneously permanently alter my memories, consciousness, and even my personality!"

"And the excruciating pain of having one's bones ripped out is not an option, really not an option."

"It might work against those with weak wills, but against those with strong wills and deep-seated hatred, even the most ruthless methods won't make them afraid."

"For example, Neville's parents, when tortured by the Death Eaters with the Cruciatus Curse, never yielded, and eventually even went so far as to be driven insane by the curse."

"This kind of torture is really not good; it's too brutal."

"The Crucible Curse I want will not only torment the enemy's body, but also their mind. It seems to be able to combine with the Mirror of Reincarnation, so that the pain of the body and mind are intertwined. I don't need to cast the spell so many times. Just one time will be enough to make the enemy feel what it means to be in unbearable pain."

"And the same goes for other dark magic. Deep Blue is already dark magic, let's go to the extreme!"

As Charles spoke, Deep Blue began to operate wildly.

Every single second, the knowledge of dark magic that flashed through Charles's mind was enough to make those self-proclaimed masters of dark magic pale in comparison.

Even if all the dark wizards in the entire magical world were gathered together, it's unknown how long it would take to complete so many improvements to dark magic.

And the things that flashed through Charles's mind were too evil, too extreme.

Compared to these things, even the most ruthless dark wizards are as docile as sheep!

After all the dark magic spells Ciel knew had been deduced three times, Ciel opened his eyes and felt as if he had been in another world.

This simulation was the longest in history.

Although there were only three simulations, there were so many curses involved in the simulations, and the knowledge and materials involved in the process were vast!

However, the findings following this deduction were terrifying.

The deep blue notification sound rang out like a screen being flooded with notifications.

"The Soul-Stealing Curse has been deduced three times. The host has obtained the mental spell - Soul Reconstruction."

"Based on the Soul-Stealing Curse, combined with the Soul-Stealing Curse's derivative spell, the Mirror of Reincarnation, continuously manipulates the cursed person's life and spirit in each reincarnation, permanently altering the other person's memories and consciousness with each reincarnation."

"The greater the difference in mental strength, the more significant the modification effect. For cursed individuals whose mental strength is inferior to the host's by more than an era, the host can even modify them into a completely unfamiliar personality!"

"..."

"The Heart-Piercing Curse has been deduced three times. The host has obtained the mental curse - Pain Piercing the Heavens."

"Unlike the Cruciatus Curse, which purely creates extreme physical pain to destroy the spirit, this curse also incorporates other materials from the host's mental spells, which will amplify the mental pain of the cursed person many times over."

"The cursed person will experience the extreme pain that destroys their spirit. The pain of a lifetime will appear before their eyes, and even the strongest spirit will suffer a heavy blow."

"..."

After the side effects were removed, the black magic was pushed to even more extreme directions.

At this moment, Ciel can be considered one of the only three masters of dark magic in the near-ancient era.

While he may not be as proficient as Grindelwald and Voldemort in terms of absolute depth of dark magic, the breadth of his knowledge in the realm of dark magic is unmatched by either of them.

After all, human energy is limited, and Grindelwald and Voldemort are no exception; they could not possibly master everything in the realm of dark magic.

But Ciel is different; he is proficient in almost all of the current dark magic!

Fiery flames, malicious transformations, evil curses, curses...

Charles is omniscient!

Especially in the niche field of black magic, curse magic, Sharl's mastery is unparalleled in this era.

After all, this thing doesn't cause direct damage, and compared to the Killing Curse that can kill enemies directly, it's still too ineffective.

Therefore, among the already limited number of dark wizards, very few have ever studied curses.

In the wizarding world today, the most famous curse still comes from Voldemort's curse on the Defense Against the Dark Arts class at Hogwarts.

He traveled through Europe and underwent several transformations using dark magic, which greatly enhanced his abilities. However, he failed to obtain the position of Defence Against the Dark Arts professor at Hogwarts, and thus cursed that no one could stay in that position for another year.

To be honest, this curse is rather ridiculous, and it's been around for quite a few years.

But the effects of the curse are still ongoing.

Even Dumbledore couldn't do anything about this curse, and could only change the Defense Against the Dark Arts professor every year.

Even Hogwarts' protective magic could not withstand this curse.

This is enough to prove that the field of curse magic is too niche, and even the most top wizards have no solution to it.

Now, Ciel's mastery of curse magic far surpasses that of Voldemort back then.

In this field, he claims to be the strongest in the world, without any doubt!

Even at Hogwarts, right under Dumbledore's nose, Shire's curses could leave Dumbledore helpless!

A slight smile appeared on Charles's lips.

"Furthermore, I remember my spacetime marking magic, which allows me to curse those marked from thousands of miles away."

"I just never had the chance to deduce the curse before, but now I can finally make use of this feature."

"You know what, they're really good at being disgusting."

"If that old bee Dumbledore ever bothers me again, I'll teach him a lesson with my curse magic!"

In addition, Ciel's mental strength also soared after these dark magic deductions.

So many spells being deduced three times simultaneously also implies a vast amount of knowledge.

At this moment, Xia Er filled all the knowledge generated in this process into his memory palace. The area of ​​the memory palace has expanded by nearly half compared to before, which naturally provides a significant boost to Xia Er's mental strength!

Even without deducing the Killing Curse, these dark magic deductions alone have raised Ciel's strength to a whole new level!

After digesting these gains, a burning light ignited in Charles's eyes.

"Well then, it's finally time for the Killing Curse."

"Deep Blue, perform the deduction!"

"The first two simulations followed the same direction as before: removing unstable casting conditions and side effects. As for the third one..."

Charles pondered for a moment.

The Killing Curse is an instant death curse, and its power is already extreme enough. Even if the power is increased, a person can't die twice, right?

Therefore, we don't need to continue to speculate on its power for the time being; instead, we need to focus on its accuracy.

Therefore, Charles gave the order to Deep Blue.

"For the third simulation, I want to significantly increase the hit rate of the Killing Curse, ideally giving it an automatic target-hunting function!"

Even Voldemort would have cursed the Shire for being insatiable if he heard such a request.

Does the Killing Curse automatically lock onto enemies?

What kind of good thoughts are you having!

But Deep Blue remained silent and took on everything in solitude.

A moment later, a deep blue notification sounded in Xia Er's mind.

"The Killing Curse has been deduced three times."

"The host will no longer need to harbor murderous intent when casting the Killing Curse."

"The host will no longer suffer from side effects such as mental distortion when releasing the Killing Curse."

"The Killing Curse cast by the host will interact with the Time-Space Imprinting Curse. The Killing Curse will constantly track the location of the Time-Space Imprint and adjust its trajectory until it hits its target or its magic power is exhausted!"

Charles took a deep breath, a look of surprise on his face.

He hadn't expected that, although Deep Blue couldn't make the Killing Curse itself have the ability to target enemies, it could indirectly achieve this through the Spacetime Imprint Curse that he had previously deduced.

The Time-Space Imprint Spell was already considered the most irresistible spell in Ciel's hands. Even that ancient being in the Dragonblood Sea of ​​Romania could only watch helplessly as Ciel imprinted the character "拆" (demolish) on his coffin.

Even Dumbledore probably couldn't do anything about the Imprint of Time Charm.

In other words, it is very easy to imprint a time-space mark on an enemy.

By using the spacetime imprint, the Killing Curse can continuously target enemies, greatly increasing its hit rate!

The next moment, Charles looked up at the sky and his gaze fell on a bird.

With a wave of the wand, a time-space imprint was instantly imprinted on the bird.

Then, Ciel recited the unforgivable curse.

"Avada Kedavra".

A dazzling green light shot out instantly and then flew into the sky on its own.

This magic, imbued with the aura of death, terrified even birds, who frantically flapped their wings, trying to escape.

But the green light of the Killing Curse seemed to have a life of its own, chasing the birds and tracing arcs before hitting them precisely.

In an instant, the bird lost its life and plummeted straight down from the sky.

Seeing this, Charles nodded in satisfaction.

In this way, even if the enemy is riding a flying broom or some other flying device, his killing spell can hit accurately!

Unless the enemy flies too far in this short period of time, causing too much of the killing curse's power to dissipate, they will be killed.

If Voldemort had developed the Killing Curse to this extent in the original books, Harry Potter would have ended long ago!

However, Ciel then licked his lips.

He still has plenty of points; he hasn't even used up any points to deduce so many dark magic spells.

The Killing Curse is definitely worth exploring further.

"The hit rate of the Killing Curse has been solved, but it still has a problem: it can only target a single enemy and cannot attack multiple enemies at once."

The classic spell from some fantasy games in his previous life—Chain Lightning—came to mind.

Once it hits one enemy, the spell will chain and jump to hit even more enemies.

If the Killing Curse could do the same, wouldn't it truly become a powerful crowd-clearing technique in large-scale battles?

One fatal curse and a whole battlefield is wiped out!

Once the idea popped into his head, Ciel couldn't stop himself.

"Deep Blue, the Killing Curse, fourth deduction..."

"Push it in the direction of enhancing area-of-effect attacks, the idea is Lightning Chain."

"Bring me a Killing Curse lightning bolt!"
