Hogwarts: Why do you call me the Demon King?

“Follow me.” Isaac walked ahead quickly along the “alley” past the rickety bookshelves and towering boxes.

"This is it."

Isaac recognized the skeleton of the five-legged creature, the corner crammed with flying brooms, and the large cabinet corroded by strong acid.

What they were looking for was on top of the cabinet; the ugly, chipped half-length stone statue of the old wizard was still standing there.

The dusty old wig and the faded ancient headdress it wore were none other than the Ravenclaw crown.

“Are you ready, Professor Venda? Just as we planned when we arrived.” Isaac’s eyes were fixed on the crown before him.

His hands were trembling slightly.

This wasn't out of fear, but rather out of excitement—Dumbledore hadn't taken Quirrell with him when he killed him.

Now it's Isaac's turn to face Voldemort's remnant soul.

If Isaac were facing the complete Voldemort, he wouldn't have shown himself before Voldemort without anyone persuading him.

But now it's just a remnant soul.

"Hoo..." Isaac sighed, and the next second he waved his wand: "The tiara, come here!"

Chapter 42 Why doesn't your fire snake have a nose?

As Isaac's Summoning Charm took effect, Ravenclaw's tiara flew toward Isaac with a "whoosh".

When the crown was halfway through its flight, Professor Venda, who was behind Isaac, stepped forward.

Her wand pointed directly at the crown in mid-air, and then flames erupted from it.

This is not an ordinary flame.

As the person standing next to Professor Venda, Isaac had the most obvious perception of the flames in her wand.

This flame is alive and conscious.

Fierce Fire.

Fiery Blaze is not an ordinary flame; it possesses a certain degree of self-awareness and perception, and will actively search for and pursue all living beings.

At the same time, the flames will constantly transform, turning into huge fire dragons, chimeras, fire snakes, birds of prey, and other ferocious beasts, using sharp teeth and claws to devour their prey.

Most importantly, once the Fiendfire spell is cast, the Fiendfire will continuously devour flammable materials and grow stronger, with its power increasing exponentially.

In the original timeline, Malfoy's henchman Crabbe used the Fiendfyre spell in the Room of Requirement.

However, this guy had absolutely no way to control his Fiendfire—generally speaking, ordinary dark wizards don't like to use the Fiendfire spell.

Because they themselves can't control this thing.

But Professor Venda is not an ordinary dark wizard.

She was Grindelwald's second-in-command, and Grindelwald was a master of dark magic who wielded Fiendfire with incredible skill.

When Professor Venda unleashed Fiendfire, the Fiendfire, detached from her wand, did not immediately begin to devour the surrounding flammable materials to grow stronger.

Instead, it directly solidified its "beast form" in mid-air.

The raging flames transformed into a raptor soaring in mid-air, then viciously clawed and pecked at the falling crown.

Just as the Fiendish bird was about to touch Ravenclaw's crown, Isaac and Professor Venda suddenly heard a vicious scream.

Immediately afterwards, a large amount of dark tar-like substance, like blood, gushed out from Ravenclaw's crown.

Immediately afterwards, a large amount of black mist will be emitted.

Isaac could see clearly that the black mist seemed to be trying to form a human shape. Unfortunately, it appeared a little too late.

The howl emanating from Voldemort's remnant soul did not affect Professor Wenda.

Just kidding, he used to be with Grindelwald. While Grindelwald was conquering Europe, little Tom was probably still in school.

Under Professor Venda's control, Fiend Raptor charged directly into the black mist, causing Voldemort's remnant soul to scream in agony before fiercely burning Ravenclaw's crown.

A few seconds later, the screams stopped abruptly, and the crown that had been automatically floating in mid-air fell to the ground.

After the crown was completely burned, Professor Venda didn't have time to examine the remains on the ground; she now had to deal with the Fiendfire she had created herself.

There's no way around it; that's just how the Fiendish Curse is. Its danger doesn't actually lie in the power of the curse itself.

The key is that this thing has its own consciousness, is uncontrollable, and most importantly, it can infinitely expand its power by igniting combustibles.

Grindelwald might be able to manipulate Fiendfire at will, but Professor Venda could only influence it to a limited extent.

Just like before, control the Fiendfire so that it doesn't devour flammable materials first, but instead devours the life force belonging to Voldemort within Ravenclaw's crown.

To put it bluntly, once the Fiery Blaze appears, it will inevitably devour the surrounding life force—this is the Fiery Blaze's instinct.

Professor Venda can have Fiendfyre bypass A and B and devour life force C, which is Voldemort, among life forces A, B, and C.

But once life force C is devoured, the Fiendfire will eventually devour A and B, namely Professor Venda and Isaac.

At this point, Fiendfire will become increasingly difficult to control, and its own will will constantly struggle with Professor Venda for control of the flames.

Fortunately, after destroying Voldemort's Horcruxes, Professor Venda no longer needed to forcibly control Fiendfire.

She immediately stopped casting the Fiery Spell, and the Fiery Spell, which had broken free of its restraints, instantly transformed from a raptor into a giant fire serpent.

Isaac felt there was something wrong with the fire serpent's head. Why did it look so round and bumpy with no nose?

Isaac thought quickly, but Professor Venda acted even faster.

Professor Venda, having ended the Fiendfyre spell, immediately pointed her wand downwards and uttered the standard incantation for the first time.

"Finite Incantatem (All Curses End)!"

Professor Venda's wand landed easily on the floor of the Room of Requirement, and a bright golden light immediately emanated from it.

Then the golden light quickly extended upwards, forming a straight golden pillar that stretched from the ground to the ceiling.

The noseless fire serpent was blasted into the sky by the golden light and slammed hard into the ceiling.

The scattered sparks were blocked by the golden light.

Finally, the golden light spread outwards along the ground, forming a huge circular golden halo at Professor Venda's feet, and the barrier rose up.

The edge of the halo began to curve upwards, gradually forming a hemispherical, transparent golden barrier that protected Professor Venda and Isaac within it.

The surface of the rising barrier was covered with intricate alchemical symbols and ancient magical runes, which shimmered continuously as energy flowed.

Under Professor Venda's constant manipulation, the protective barrier between them continued to expand, eventually annihilating the fire serpent in mid-air.

Only at this moment did Isaac truly witness the terrifying scene of a powerful wizard actually using magic in combat.

The time Dumbledore fought Voldemort's ghost doesn't count.

At that time, Dumbledore beating Quirrell was no different from beating his son... no, it was no different from beating his grandson.

So from a visual effects perspective, it's nowhere near as spectacular as it is now.

Professor Venda's self-production and self-sales made Isaac understand the extent to which powerful wizards could achieve.

At the same time, his fear of the Fiery Curse deepened.

Isaac was originally very interested in Fiendfyre; Grindelwald's gas stove was the best advertisement for Fiendfyre that year.

Anyone who can learn magic and has seen this scene would want to use the Grindelwald Fiery Flame Gas Stove in a frenzy.

But this thing is really hard to control; if you're not careful, it can backfire on the caster.

Before Professor Wenda could even unleash the Fiery Blaze to devour the surrounding flammable materials, the once elegant Professor Wenda was already panting heavily.

If Isaac were to secretly practice this thing at Hogwarts, and accidentally give it to the castle or the Forbidden Forest, who else would go to Azkaban if not him?

Most importantly, Isaac has always held the view that only spells that can be completely controlled by a wizard are truly his own.

Perhaps in the future, when he becomes powerful, he can freely use the Fiery Blaze to show off.

However, for now, let's put the research on the Fiery Curse on hold for a while.

"Professor Venda, are you alright?" Isaac asked softly, by which time Professor Venda had caught her breath.

The two then went to the spot where Ravenclaw's crown had just fallen.

Chapter 43 Tom the Prodigal Son

Isaac and Professor Venda arrived at the spot where the crown had just fallen, only to find that the once intact crown had been reduced to fragments.

The fragments were pitch black, yet the inscriptions that were originally engraved on the crown were still clearly visible.

"Exceptional wisdom is the greatest wealth of mankind."

Isaac waved his wand and pieced together the fragments on the ground, eventually restoring the inscription on the crown.

"Exceptional wisdom is humanity's greatest wealth..." Professor Wenda repeated the words on the crown.

Even though Isaac had already told her what they were dealing with on the way.

But when Professor Venda personally "burned" this "holy relic" in the hearts of all Ravenclaw wizards, she couldn't help but feel a little sad.

She had heard of Ravenclaw's tiara even when she was in France.

As a result, the sacred artifacts that should have been passed down within Ravenclaw were instead turned into evil Horcruxes.
