Clash

"I thought Armando and the others had already dealt with Fiendfyre." Dumbledore frowned deeply, his expression grave as he spoke to Grindelwald. "So the reason Fiendfyre hasn't spread throughout Hogwarts yet isn't because it's been dealt with, but because you've kept it under control?"

"Of course, do you think those cowardly and incompetent so-called professors could handle the Fiendfyre that I personally sealed?" Grindelwald grinned.

Seeing this scene, Xiwen suddenly realized what was happening, and his face immediately turned very ugly.

"So, you're the only one who can quell Grindelwald's Fiendfyre, Dumbledore?" he asked, looking at Dumbledore.

"I'm afraid so." Dumbledore nodded slowly.

"I understand now. Grindelwald had Pinkstone destroy the Magic Node at this time to force you back to Hogwarts, thus breaking our encirclement plan against him." Xiwen glanced at Grindelwald, who was watching the two of them with a half-smile in the distance, and couldn't help but sigh. "He knows you can't abandon the students of Hogwarts."

"We may have made a fatal mistake this time."

"I'm sorry, Xiwen, it seems I have no choice but to leave this place to you," Dumbledore difficulty. "In the most urgent situation, I hope you can leave here directly through the portal. Your own safety is the most important thing."

"If I just run away like this, all our efforts over the past six months will have been in vain," Xiwen shook his head and said to Dumbledore. "From now on, those proud Pure-blood will never recognize a leader who has fled in such a sorry state!"

"But you must know that as long as he's alive, there's hope. You absolutely cannot afford any mishaps," Dumbledore said in a deep voice, looking into Xiwen's eyes.

At this moment, Grindelwald, whether out of boredom from standing there alone or because he didn't want Dumbledore and Xiwen to get too close, interrupted their conversation.

"Albus, I'm not sure how long Fiendfyre will remain stable at Hogwarts. Don't you care about your students at Hogwarts?" he said casually, toying with his wand.

Dumbledore cold look, then turned his gaze back to Xiwen.

"Take care of yourself, Xiwen!" he said.

"Don't worry, leave this to me," Xiwen replied solemnly. "I also want to see how long two of me can hold off Grindelwald."

Accompanied by a Phoenix -like golden-red flame, Dumbledore disappeared into Lestrange Mausoleum, returning to Hogwarts Castle to resolve the issue of the Magic Node.

Now, only Xiwen and Grindelwald stand face to face on the stone platform, confronting each other.

"Now it's just the two of us, Mr. Rozier," Grindelwald said with a smile. "Without Dumbledore backing you up, are you still determined to detain my friends?"

Xiwen looked at him and sighed softly.

"Why not offer appropriate compensation beforehand?" he said softly.

The next moment, the two of them simultaneously raised their wands.

"There's no need for anyone else to get involved in our duel. Let them stay away," Xiwen said loudly. "They'll only serve as sacrifices in our duel."

"Of course," Grindelwald laughed.

Both men waved to their subordinates, signaling them to move away from where they were dueling.

Then, Grindelwald unleashed a powerful spell the thickness of a fist, which shot towards Xiwen in the blink of an eye.

The two Xiwen, standing side by side, were of one mind. One of them spread his wings and flew into the sky, while the other drew a golden circle in front of him, changing the direction of Grindelwald's powerful spell so that it crashed straight into his own position.

Unexpectedly, the spell that shot out from the other golden halo was still under Grindelwald's control. With the wave of his wand, the spell circled around Grindelwald's body like a dragon, flying up and down.

The spell, originally only as thick as a fist, continuously absorbed magic from the air as it flew, and with Grindelwald constantly adding power, it grew stronger and stronger. In the end, it formed an overwhelming aura, rushing towards Xiwen like a tidal wave.

As Grindelwald's spell grew stronger, the sky above the mausoleum gradually became overcast, with thunderclouds flashing with continuous bolts of lightning.

At the critical moment, a thick bolt of lightning, carrying immense force, struck Grindelwald's overwhelming spells. This lightning bolt contained both the blue lightning generated by the Weather Charm and the yellow lightning coiled with the Borsat's Lightning. The intertwining of blue and yellow created a terrifying and awe-inspiring power!

As Xiwen remained close to the ground, he simultaneously formed hand seals, pushing forward with both hands to create a violent gust of wind that redirected Grindelwald's spell, allowing it to collide with the descending lightning and shatter the spell onto the stone platform.

"Boom!"

The deafening roar seemed to shatter the eardrums of everyone present. The stone platform, which had withstood the raging flames thirteen years ago, was destroyed once again, sending up clouds of rubble and dust.

Under Grindelwald's control, the spell that filled the mausoleum, soaring like a dragon, was slammed into the ground by the first bolt of lightning. Under such thunder and lightning, even a soaring dragon had to temporarily bow its head!

And the thunderbolts were not just one.

The lightning strikes came one after another, relentlessly bombarding the spell, gradually eroding and dissipating its magical power until it finally dissipated into the air.

The curse was gradually crushed, and the crimson clouds could no longer gather the power for the next wave of lightning. The dazzling lightning slowly faded away in the mausoleum.

As the light faded, Grindelwald's figure appeared on the shattered stone platform. The square foot of the platform beneath his feet was the only intact spot on the field.

"Using the power of Weather Charm to break my spell, quite a brilliant idea," Grindelwald said with a smirk of interest. "But if you can no longer fly, can you still accumulate such a massive amount of thunderclouds?"

With that, he waved his wand with a flourish, and a ripple that enveloped the entire mausoleum swept over Xiwen's floating figure.

He instinctively flapped his wings, but felt a gravity far exceeding the Earth's gravitational pull, and was forced to crash heavily into the ruins on the ground.

"This is... Landing Charm." Xiwen frowned.

Charlus Potter had used this move on him before on the sixth-grade dueling stage, which resulted in a draw in that duel.

However, when Grindelwald used the same spell this time, it turned into a wide-range curse, with nowhere to dodge it!

"That's enough, Mr. Rozier," Grindelwald chuckled.
