Bang, bang, bang…"
Amidst the heavy thuds and the sound of shattering stone, the mutated Elvis Heller proved to be incredibly valiant.
He even managed to break through such a terrifying heavy cavalry charge, rushing into the Stonehenge and heading straight for the altar.
Under Karl's gaze, Dumbledore used a super Protego to block Elvis Heller's advance.
"Crack!"
Like the sound of shattering glass, the long spear pierced through the invisible magic barrier.
Although it was only for a brief moment, it was enough; Dumbledore swept his sleeve, and the plaza below the altar transformed into a surging mudslide.
After crashing into Elvis Heller and carrying him dozens of meters away, it then turned into shackles, heavily surrounding him.
"Principal, this won't hold him."
"Don't worry, Karl."
Dumbledore elegantly drew circles with his wand, and a flock of small birds quickly flew towards Elvis Heller.
"Avifors?"
Karl was full of questions; even his Fiendfyre couldn't burn through that strange blood-red light, so what good would this do?
The Bird-Conjuring Charm was actually a Transfiguration spell invented based on the Multi-Blast Charm, similar to the Bat-Bogey Hex and others.
However, compared to the power of Multi-Blast, Avifors was only suitable for Young Wizards to use in fights.
"Get lost!"
Just as Karl was wondering, Elvis Heller once again unleashed the power of his long spear, and the blood-red light broke through the shackles, then collided head-on with the flapping birds.
The birds struck the blood-red light on his body, quickly turning into white flames, which soon transformed Elvis Heller into a human torch.
"What kind of flame is this?"
Karl clearly felt that this white flame wasn't powerful, yet it miraculously wasn't dispersed by the blood-red light.
"Gubraithian Fire. It doesn't compare to the power or sentience of Fiendfyre, nor is it dangerous, but it has an advantage that other flames lack: it can burn forever, earning it the name 'Eternal Flame'."
While Dumbledore was explaining to Karl, he pointed his wand at the human torch, shooting out a thick red beam of light.
As Elvis Heller panicked from the Gubraithian Fire, Dumbledore knocked him to the ground.
The blood-red long spear was also knocked away, landing in the distance, and was then swallowed underground by shifting stone bricks.
"Karl, don't just focus on the power of the spell; strategy in combat is equally important."
"The powerful one is that long spear, not Elvis Heller. If you can't defeat the opponent head-on with a spell, then find a way to disarm him first."
"In fact, you could have completely defeated him; you just relied too much on Fiendfyre, which was the wrong choice."
Dumbledore gently beckoned, and the stone slab where Elvis Heller lay moved like a small boat, carrying him towards them.
"To become a master duelist, you must learn a great many spells and use them flexibly in battle."
"Even if your Fiendfyre Curse is already masterful and allows you to defeat most Wizards, relying solely on Fiendfyre won't suffice."
At this point, Dumbledore seemed lost in thought for a moment, perhaps recalling Grindelwald.
That person's Fiendfyre Curse was unprecedented, and he was equally outstanding in other areas.
"If you encountered a spell master like Filius, he would certainly have a way to deal with Fiendfyre."
"Or a Transfiguration master like Minerva could even turn your Fiendfyre into another substance and use it for herself."
"And if it were a Dark Wizard like Lord Voldemort, who also knows the Fiendfyre Curse, even if he couldn't compare to you in manipulating Fiendfyre, he would know how to avoid its harm."
Karl nodded, quickly committing the Principal's teachings to heart.
Excluding the newly acquired Ice Phoenix form, he would indeed find it difficult to win against top-tier Wizardmasters.
Seeing Karl's serious expression, Dumbledore smiled with satisfaction, "But don't worry, because the few people I mentioned are extremely rare in the entire Wizarding world."
"In fact, the strength you possess at your age can already defeat the vast majority of Wizards."
Karl chuckled, then asked shyly, "Principal, can you teach me Gubraithian Fire?"
Dumbledore opened his palm, and a ball of white flame appeared out of thin air.
"Of course, but you need to be prepared, because this is a rather profound magic, and learning it… Eh?"
Under Dumbledore's surprised gaze, Fire Treasure and Fawkes poked their heads out from Karl's embrace.
"Chirp?"
Fire Treasure curiously flew in front of Dumbledore, circled the Gubraithian Fire twice, and then swallowed it in one gulp.
"Yay!"
The warm sensation made Fire Treasure comfortably narrow its eyes, then it raised a hand and summoned a ball of Gubraithian Fire, wearing it on its head like a hat.
Then it flew back in front of Karl to show off, asking for his evaluation, "Chirp?"
"Beautiful! Absolutely beautiful!"
If Dumbledore hadn't been there, Karl would have definitely hugged Fire Treasure and given it a big kiss.
So it could do that? This little guy really was his precious darling!
It was a shame there was no Fiendfyre at school, otherwise he wouldn't have had such a hard time learning the Fiendfyre Curse back then.
"Well, it seems I don't need to teach you anymore," Dumbledore said with a smile, shaking his head. "When you have time, go to my office and get a copy of my notes on studying Gubraithian Fire; you can practice it yourself."
"Thank you very much then!"
Karl happily placed Fire Treasure on his head, and then put its little companion, Fawkes, up there too.
In just this short time, Fawkes had already grown downy feathers, which felt very nice, making him Can't help it rua it a few times.
Fawkes rubbed Karl with its beak, then looked a bit puzzled. Why had this boy become so affectionate?
Especially after its own rebirth, this feeling had grown stronger and stronger, as if the other party was of the same kind as itself.
Hmm… It must be because of Fire Treasure.
After all, the other party was a Fire Treasure, not a Phoenix but more like one; it must be so.
Having sorted out the Gubraithian Fire, Karl turned his head to look at Elvis Heller, whose breath had ceased.
"Heller is finished just like that?"
"Of course not. Don't forget he is a follower of Herpo the Foul."
"You mean Horcrux? But Heller didn't say that thing couldn't grant immortality… Oh! I understand!"
Karl realized that although a Horcrux couldn't grant eternal life, making one for self-preservation was excellent.
And Heller, who was aware of the Horcrux's drawbacks, would surely protect his Horcrux well, unlike Lord Voldemort who hid them everywhere.
As long as he solved this problem, he wouldn't have to worry about being trapped in a delusional realm after death.
Not to mention this guy also firmly believed that his so-called Lord Herpo the Foul could grant him immortality.
"Lord Elvis Heller, how much longer will you pretend?"
Facing Dumbledore's question, Elvis Heller's soul emerged from the corpse in a faint black mist.
"Do you think it's over just because you defeated me? Don't get complacent! Our game has just begun!"
"You win this time! But next time, it won't be this outcome!"
After saying his harsh words, Elvis Heller was about to leave, but unexpectedly, the Stonehenge suddenly lit up with a golden light, like a dome that isolated everything.
"This is…"
Dumbledore winked at Karl with a smile, "I just learned a sealing spell here, and I didn't expect it to come in handy."
Karl: (⊙ ˍ ⊙)
Huh? You've been standing here with me all this time; when did you learn a spell?
Is this what a great Wizard is like?
