From Azkaban to Hogwarts.

Then, Filch's mouth gaped open, and he even put his hand to his forehead, his face full of disbelief and suspicion as if a student had secretly given him some kind of magic potion.

In mid-air, Albus Percival Woolfrirk Bryan Dumbledore, the renowned recipient of the Order of Merlin, First Class, Headmaster of Wizengamor, President of the International Confederation of Wizards, the greatest white wizard of our time, and Headmaster of Hogwarts, floated gracefully, skillfully using his wand to ensure a stable landing.

The mischievous seventh graders even peeked out and began cheering for their beloved principal…

'It's over, Hogwarts is doomed...'

Filch felt a heavy weight on his heart, an indescribable discomfort.

But because of his duty as an administrator, he looked up and discovered that a figure was floating in the sky near the castle, using a broom, and that figure was even using a wand to break the classroom windows.

“Professor McGonagall, it seems we need to use the highest level of protection.”

William shouted at the broken glass, then swooped down towards the ground, landing on the broom about two people off the ground, using a rope attached to the broom to slow his speed down.

Inside the classroom, the students stared in disbelief—Professor McGonagall, who had never allowed anyone to disrupt her lessons, had actually stopped teaching and even stood by the window, looking down at the students.

Harry and Ron quickly moved closer to the window.

'Professors, the principal, and Professor Lupin?'

Harry was stunned. He didn't know why Professor William had suddenly come over and tore down the window of Professor McGonagall's classroom, nor why Professor McGonagall wasn't angry, and he didn't know why Professor William's landing looked so awkward—well, in short, not very skillful.

However, the next second, in full view of everyone, a door key was activated, and the principal and professors downstairs disappeared instantly.

"get out of class dismissed, go back to the common room!"

Professor McGonagall glanced downstairs again, called out to the students below, and then walked down the corridor.

A few minutes later, the prefects were called to the classroom.

"Now, inform everyone to return to the common room. All classes are suspended. Hogwarts is on high alert!"

Chapter 605 is almost over

"Bart should have gone to Professor Flitwick with the note I gave him a long time ago. Hopefully, Professor Flitwick can keep a close eye on Snape—the Dark Lord's ability to turn people against him is even more terrifying than I thought..."

"What exactly caused the Dark Lord to fall into the trap? Did he finally discover Dumbledore's 'death'? Or was there a traitor among the Strikers?"

"Or perhaps my proposed population relocation plan has been exposed?"

"... "

"I'd made so many arrangements, I was even prepared to join this wizarding war, and yet the Dark Lord has been captured..."

As the key turned on, several thoughts raced through William's mind, but they were all interrupted by the strange squeezing sensation when the key was activated.

Dumbledore would never rashly inform anyone. The Dark Lord is now in dire straits, and what he needs to do is go and lend a hand, preventing the Dark Lord from finding a chance to escape.

Before the dizziness from the door key had subsided, William quickly cast the Iron Armor Charm on himself and his two colleagues.

Along with it came an extremely vivid, scorching green curse that made the air feel hot. It pierced the sky at a speed that was difficult to react to, and then crashed into a clay sculpture that had suddenly stood up, scattering mud everywhere.

William immediately rolled to the left and plunged his left hand into the lake. The next second, the dark lake water, illuminated by the few torches, flowed upstream and adhered to William's armor curse, making him appear several sizes larger.

“Professor Dumbledore,” William called out, his wand never stopping, “aren’t we here to kick a man when he’s down?”

"I'm sorry, Professor William, there seems to be a slight misunderstanding between us."

A ring of fire burst forth again, illuminating the lamps that had appeared on the cave ceiling at some unknown time.

Dumbledore stood at the entrance of the cave, behind him a large mass of dark clay sculptures, while in front of him, piles of clay made William frown – so Dumbledore was being blocked at the door and beaten up?

"Three more suicides have been brought in, and they're Hogwarts professors, aren't they?"

Voldemort's crimson eyes, with several silver shields floating before him, even dimmed the brightness of the lamps that Dumbledore had somehow replaced on the cave ceiling. "Is that all, Dumbledore?"

As he squinted and consulted, a violet spell flew directly towards William, clearly indicating that William's previous words had angered the Dark Lord.

The magical path struck the water shield, but instead of dissipating, it exploded with a bang, forming countless flames that directly enveloped William.

"An old man who should have retired long ago—and three good-for-nothings? Oh no, now there are only two left?"

He snorted contemptuously through his nose, a sound that even stunned William, who was hiding in the water preparing his magic—the previous magic was ridiculously powerful, which was understandable, but how did the Dark Lord find and use that non-existent nose?

"Where are the Aurors from the Ministry of Magic, Dumbledore? You don't expect these people, plus you, to hold me back, do you...?" He casually cast another spell at Moody. "Or are you going to tell me that you're the imposter, and the real one is someone who arrived later?"

A clay sculpture appeared in front of Moody, but Moody clumsily dodged the attack, leaving the clay sculpture shattered into pieces. "I'm not quite used to this body yet, Dumbledore, your eyesight is terrible!"

"And there's this guy who can use shapeshifting..."

Voldemort lightly pointed his wand at the ground, thwarting Lupin's attempt to turn the ground into a swamp. "Another disgusting Gryffindor..."

'What's going on...'

William swung his wand directly out of the water, spinning the already formed ice ball towards Voldemort, and then he couldn't stay underwater any longer—even his own spells, with their overflowing chill and dark magic aura, had already made a mess of the area where he was, not to mention that the following magic was so powerful that he didn't even want to withstand his own attacks.

The rapidly spinning ice puck created a whooshing sound, and pale blue, water-drop-like objects were flung out at high speed, dripping onto the ground. A few drops occasionally touched the water's surface, quickly condensing into strange clumps of violet ice.

"Tom, let me tell you why the Auror didn't come. After discussing it, we still feel that you've infiltrated the American wizarding world too quickly. If we inform the Auror, it will only create unnecessary risks."

Dumbledore watched William make his move, raised his wand to Voldemort, his tone remarkably calm, and even prepared a spell—but this still didn't work.

The ice ball didn't slow down at all; instead, it moved even faster towards the Dark Lord, only to be blocked halfway by a silver-white shield that suddenly appeared. The next moment, the entire ice ball exploded, and countless blue water droplets wrapped around the shield, falling to the ground and condensing into countless ice spikes in Voldemort's direction.

But it was too far; even the longest ice spike was an insurmountable distance from Voldemort.

"Dark magic..."

Voldemort laughed. "Dumbledore, you've actually brought a powerful dark wizard to ambush me—are you willing to do anything to kill me?"

"What black wizard? How can I, a professor of self-defense, teach if I don't know black magic?!"

William shouted as he unleashed a spell—a ball of fire exploded directly at the silver-white shield. The shield, which was already barely holding on under the influence of dark magic, shattered into countless pieces after being struck by the flames and vanished into thin air.

William then began to manipulate the ice crystals underground using Transfiguration, attempting to trap Voldemort in place.

But this allowed Voldemort to casually swing his wand, shattering the ice crystals into countless fragments.

"Is that all you've got? Even Dumbledore couldn't use Transfiguration to completely control the environment around me—who gave you the courage?"

However, just as Voldemort was about to speak, Dumbledore had already summoned a fire rope with his wand, which went straight towards Voldemort and interrupted his attempt to mock him.

Almost simultaneously, Lupin cast a spell around the area that William didn't recognize, forcing Voldemort to summon his shield again to block the attack.

Moody, meanwhile, cast another spell close to the ground, forcing Dumbledore to focus on defense before he could launch his attack.

'That's really despicable, ganging up and hitting the ground.'

While cursing under his breath, William unleashed a mutated spell of raging flames in mid-air, greatly increasing the brightness of the flames and engulfing Voldemort.

But a shield of flame suddenly appeared and spread across Voldemort's entire body, instantly melting away the sorcery of Lupin, Moody, and William. Just as Dumbledore's fire rope was about to wrap around him, it suddenly transformed into a venomous snake, which instead lay at Voldemort's feet. After a brief pause, it began to attack Moody.

"fuck your mother!"

William heard Moody utter a heavily accented curse, and then saw Moody swing his wand violently, sending the snake flying into the air, tying a knot in it, and then tearing it off. Afterward, he ripped open his wizard's robes, took a sip of a potion, and his entire body began to shrink.

Dumbledore's clay figure appeared just in time to shield Moody from the impending fatal attack—although Moody had taken comprehensive precautions, Dumbledore was still somewhat uneasy.

"Surrender, Mr. Voldemort."

While Moody was slapping his eyeball into his eye, William waved his wand to summon a large pool of lake water as a reserve for his next spell, and shouted loudly.

“You’re destined to stay here. Your men don’t know about this place, you can’t get any backup, and Headmaster Dumbledore has been setting things up here for a month—do you really think you can break out the door and Apparate away?”

"If you surrender," William began to say, but before he could finish, Voldemort launched a fierce attack, hurling several spells at him relentlessly. William was forced to stop speaking and dive into the nearby water to hide.

“If you surrender, we will break your wand and send you to Azkaban to join your Death Eaters—”

As William poked his head out and shouted again, another Avada Kedavra was fired.

"Dumbledore, are you going to humiliate yourself like this? Don't you want to kill me?"

Voldemort roared, waving his wand, and another powerful spell was cast, aimed directly at Dumbledore, but it was still blocked by the dark mass of clay figures.

"Except your weapons!"

William suddenly shouted the incantation, and the enhanced Disarm Charm struck Voldemort's wand at lightning speed, only to be blocked solidly by a silver shield. To everyone's surprise, it pierced the shield and struck Voldemort, only causing Voldemort to stagger slightly, which stunned everyone present.

Even William himself had a look of ecstasy on his face—the Disarming Charm was almost the most directional spell of all, and it had excellent penetrability against defenses. He had only used the Disarming Charm to test its effect, but he hadn't expected it to work on the first try.

"impossible!"

For the first time, Voldemort's face showed a look of fear. Even Dumbledore had to use other spells to bypass his defenses, so how could they be broken through by a mere disarming charm?

“Nothing is impossible,” William said, attempting to condense an ice shield from water. He quickly stepped back and even gestured for the other two to do the same—as for Dumbledore, there was no need for that.

"You should read more of those weird stories, Dark Lord."

William's face showed regret. "In that case, you should know that there must be a conspiracy behind so much nonsense during the battle. And although the shield is powerful, there are always places it can't protect—you should get a Bubble Head Charm."

He shook his head, looking at the Dark Lord in the firelight. "I poisoned him. The water used in that compressed dark magic at the beginning was mixed with potions, and the ice it created kept piling up at your feet, then being melted and evaporated by fire spells. Plus, you kept spouting nonsense to me..."

"I was actually always afraid that you would use Fiendfire, so I only used my best ice magic once—but luckily, the potions I've been working on have been quite effective."

"Although you would have fought to the death even without using poison, using potions is an instinct for an apothecary—besides, you cursed me, and I used a potion, so we're even."

“I was lying to you before, but I think you can talk to Dumbledore now—you know, you don’t have time.”

The potion's effects became increasingly apparent. Apart from Dumbledore remaining in place to guard the exit, William and the other two gradually retreated into the darkness to prevent the trapped beast from harming them.

"Poisoning... Dumbledore, first Dark Magic, then poisoning, do you have anything more ruthless?"

Voldemort raised his wand, looked at Dumbledore, and several shields appeared around him. Clearly, he had no intention of surrendering.

William shook his head, and then, taking advantage of the Dark Lord's distraction as he turned to look at Dumbledore, he quickly transformed into Animagus and Apparated to Voldemort's side at a speed that left no time for anyone to react, directly knocking the already trembling wand off along with its arm.

"Feel sorry…"

William slammed the Dark Lord to the ground, then roughly stomped on Voldemort's broken arm, wand and all, under his foot. "I lied to you again..."

"I don't want your retaliation to cause me to lose friends or seniors..."

A series of bear roars rang out, causing the others present to show strange expressions—what were they saying?

William awkwardly shrugged, stomping hard on his wand and the severed arm until Dumbledore intervened to stop Voldemort before he began to undo the Animagus transformation.

"Feel sorry…"

He shook his head, knowing he couldn't repeat himself. "Theoretically, Apparition isn't possible here, but Dumbledore's spellcasting style is quite Hogwarts-like."

"Ha ha," Voldemort, lying on the ground and firmly restrained, laughed maniacally, "First dark magic, then poison, and finally the so-called illegal Animagus, Dumbledore, you really want to kill me that badly?"

"Shouldn't your professor be imprisoned in Azkaban? You've always been so hypocritical. Well then, kill me, Dumbledore! As you wish, tear off your veil of hypocrisy and kill me!"

"Ah, Mr. Voldemort."
