Hogwarts: I am the White Demon King

Accompanying Sebastian's low chant, blue Fiendfyre soared into the sky, steadily blocking the incoming orange Fiendfyre serpent. The serpent emitted a deafening roar, fiercely crashing against the blue Fiendfyre shield time and time again, each impact bringing with it rolling waves of heat.

Blue Fiendfyre?!

How is that possible?

The Death Eaters were dumbfounded, completely unprepared for this outcome.

Using a Fiendfyre shield for protection, a powerful spell learned from Grindelwald, was Sebastian's first time using it in battle, and it shocked everyone present.

"Lord Voldemort," Sebastian called out loudly, "blindly dodging isn't my style. Next, it's my turn to counterattack. Fiendfyre against Fiendfyre, let's see whose Fiendfyre is superior."

"This is the first time I'm formally requesting a one-on-one match with you. Don't let your subordinates ruin our fun, after all, my spells aren't very discerning."

Sebastian's threatening words angered Voldemort, but his opponent's strength forced him to take it seriously.

The Death Eaters present were all his strongest subordinates, and he didn't want to become a lone commander just after being resurrected.

Besides, who does this guy think he's looking down on?

Does he think that Lord Voldemort needs his subordinates' help to deal with him?!

How ridiculous!

So, he looked at the Death Eaters and said with authority, "I'll say it again, no one is allowed to interfere without my command."

Hearing this, the Death Eaters looked at each other in dismay.

My Lord, you think too highly of us. What are we worth? How could we possibly have the qualifications to interfere?

That's a battle between Fiendfyre, a slight carelessness and we'll be burned to ashes. How foolish would we have to be to think of playing with fire?

Voldemort ignored the Death Eaters' thoughts. He looked at Sebastian, his eyes becoming dangerous.

"Sebastian, you certainly have the qualifications to challenge me. However, your Fiendfyre is too tame. Let me teach you how truly violent Fiendfyre is."

As he spoke, he lightly waved his wand, and the orange Fiendfyre serpent instantly swelled tenfold, becoming so large that it blotted out the sky.

The violent serpent emitted an astonishing heat. The Death Eaters watching from afar felt the heatwave wash over them, making it difficult to breathe, and even their hair showed signs of singeing.

Without waiting for Voldemort's instructions, they retreated again and again, until they reached a safe distance, then turned to look at the two big shots fighting.

"My Lord is still so powerful," Barty Crouch Jr. said with a fanatical expression. "Sebastian is doomed this time. There's no way his Fiendfyre can block My Lord's attack."

Looking at the sky-covering Fiendfyre serpent, Sebastian exclaimed in admiration.

As expected of Voldemort, his Dark Arts are so slick. Just this Fiendfyre alone, almost no one in the entire magical world can match it.

However, since you're willing to teach, then I'm willing to learn.

Hehe!

From today on, this advanced Fiendfyre technique will be surnamed Swan.

The serpent roared to the sky, charging down with an aura of destroying everything. Sebastian didn't panic at all, elegantly waving his wand, like a conductor leading an orchestra, conducting his own Fiendfyre.

The blue Fiendfyre began to rotate, expanding outwards in circles, layer upon layer, blocking the diving orange serpent.

At the same time, the blue Fiendfyre continued to expand, becoming larger and larger like a giant vortex.

Watching the rapidly expanding blue fire wave, Barty Crouch Jr.'s fanatical smile froze on his face. The other Death Eaters were even more terrified, scrambling to escape to a greater distance.

Sebastian didn't intentionally target the Death Eaters. He was just controlling the Fiendfyre Shield Charm to enter the next stage.

The Fiendfyre Shield Charm is essentially an extremely powerful defensive spell, but due to the special nature of Fiendfyre, it also has considerable offensive effects.

"That's about enough!" Sebastian abruptly flicked his wand upwards. Instantly, a massive blue Fiendfyre dragon flew out of the vortex, flapping its wings and roaring, soaring straight into the sky.

He learned and applied it immediately, integrating the Fiendfyre techniques he had just learned from Voldemort into his own dragon, making it as violent and huge as the serpent.

Fire waves rolled, heatwaves swept across, and the two Fiendfyre behemoths collided fiercely in the air. The serpent tried to subdue the dragon with entanglement and tearing, while the dragon fought back with sharp claws and fangs.

The two rolled and fought in the air, devouring each other, and the resulting firestorm directly engulfed the entire deserted island.

The Death Eaters retreated again and again, finally using Transfiguration to conjure small boats, drifting far away on the sea.

"This... these two Fiendfyre behemoths are too amazing!"

"The entire island has been directly divided into two halves, one orange and one blue. To be honest, I've never witnessed such power!"

"The seawater that washed ashore directly turned into water vapor. I really can't imagine what the temperature on the island has reached now."

"Lord Voldemort, he..."

"Shut up!" Barty Crouch Jr. shouted sharply, stopping a Death Eater from saying what he was about to say. "Lord Voldemort is omnipotent. There's no way Sebastian can be My Lord's opponent. If you dare to talk nonsense, I'll kill you right now."

However, Barty Crouch Jr. didn't realize that his voice contained a trace of imperceptible trembling. Obviously, he wasn't very sure about the final outcome.

Just as he was anxiously waiting, the Fiendfyre on the island quickly retracted towards the center of the battlefield. A blinding light soared into the sky, and after a violent explosion, the whole world darkened again.

Is it over?

Who won?

The Death Eaters looked at each other, somewhat hesitant for a moment, not knowing what to do.

In the center of the battlefield, Voldemort moved away the silver shield in front of him: "Sebastian, you always give me surprises again and again. I'll invite you one last time, join my ranks, and I'll give you equal rights."

"Thank you for your kindness," Sebastian removed the layers of ice walls in front of him, smiled slightly at Voldemort, "I'm sorry to disappoint you, my answer is still no."

"What a pity," Voldemort's eyes revealed a bloodthirsty look, waving his wand and using the Anti-Apparition Jinx, "A genius like you is destined to fall here. You should feel it, although you are very strong, you are still a bit weaker than me, and that bit is the difference between heaven and earth, life and death!"

"I've noticed it too," Sebastian nodded, "Compared to you, my magic power is a little bit weaker, but it's understandable. You are one of the top wizards of this era, and I'm 34 years younger than you. Being only a little bit weaker than you is already very satisfying for me."

"However... Lord Voldemort, if you want to keep me here, you have to try a little harder."

As he spoke, his body began to tremble violently, his muscles and bones seemed to be pulled by some invisible force, becoming taller.

In Voldemort's shocked gaze, Sebastian transformed into a three-meter-tall Dragonkin giant, his right hand holding an exaggerated mace, and his left hand holding a pure white dragon bone wand.

The corners of his mouth spread open, revealing sharp teeth in a ferocious smile.

"Lord Voldemort, next is the second round!"
