From Azkaban to Hogwarts.

"Oh shit."

It sounds like Professor William's voice...

In a daze, Harry instinctively looked toward the source of the sound and saw a silver lightning bolt swirling around him.

'That was summoned by Professor William…'

In a daze, Harry saw the silver lightning bolt around him getting brighter and brighter, and getting closer and closer.

"Fuck"

He heard another swear word, and then a strange green light emanated, sending chills down Harry's spine—

"Avada!"

That familiar chill suddenly struck, and Harry immediately fainted.

-

"call…"

William gasped for breath, his body trembling slightly; his guardian spirit was almost unable to hold on.

The hummingbird, now almost transparent with its pale skin, continues to diligently fulfill its mission, but it is no longer necessary.

After the green lightning bolt was unleashed, the Dementors at the forefront calmed down and then scattered into sand in mid-air.

The gray robe that the Azkaban prisoners used to refer to the Dementors fell down with the sand, lying there tattered and torn, like a used and discarded rag.

The remaining Dementors that were charging forward came to a complete halt and stood frozen in place.

"Take the God's Protection!"

Lupin used the Patronus Charm again—this time he succeeded. A silver, canine-like Patronus flew from his wand and began to work with the hummingbird to drive away the Dementors.

With the arrival of this guardian deity, the Dementors finally scattered, fleeing in disarray, retreating, dispersing, and disappearing into the darkness…

"Huh...huh..."

William put down his wand and summoned his Patronus. The almost transparent hummingbird landed on his hand and looked at him.

“Still here,” William laughed, turning to look at Lupin, his whole body trembling except for his right hand holding the wand. “I’m not a dark wizard yet, I just used some dark magic.”

“Of course…” Lupin replied with a pale smile, “There are just too many of them. I thought I could confidently use the Guardian Angel, but it seems the happiness that supports it is weaker than I imagined…”

"Some chocolate, Professor Lupin."

William groped his way to a seat, holding his wand steadily in his right hand, then used his left hand to pull out a chocolate frog and toss it to Lupin. "Neither those grey robes nor that spell are anything to be happy about."

"Grey Robe?" Lupin chuckled, tearing open the packaging with one hand and his teeth, then biting off half of the chocolate frog. "A descriptive name... How many Dementors does that bastard Black control?"

Like William, he didn't put down his wand either—they both knew that the Dementors were just the appetizer, and the real danger was Black, whom they would face later.

They all knew Harry had fainted, but no one had time to care.

The air grew still, and the only sound was the clanging of the Hogwarts Express wheels against the rails.

The whistle suddenly sounded, and at the same time, the speeding train began to slow down.

The train has arrived at the station.

Without thinking, the tense William quickly and quietly said to Lupin, "I'll count to three, then we'll break the window and take Harry down through it."

“I observed this when I left last year. There’s a great hiding spot when the train stops. After we jump off, I’ll cast a spell in that direction, and then you follow my direction and cast a follow-up spell. If we’re sure no one’s there, take Harry and hide there!”

Lupin remained silent, but quietly cast the Iron Man Charm on himself, signaling William to pull Harry away.

"one,"

William cast the Iron Mantra on himself, then quickly followed up with another one on Harry.

"two,"

He gripped his wand tightly and then summoned the unconscious Harry directly with a Flying Charm.

"three!"

The two spells flew directly towards the window, and then, braving the Ironclad Curse, they charged straight through.

Although the Hogwarts Express was designed with numerous protective spells, it absolutely could not withstand an attack of this intensity at this distance.

The glass shattered instantly, and the sheet metal deformed violently. William and Lupin easily rolled out of the huge gap that had been created, followed by Harry, who was steadily controlled by the Levitation Charm.

William cast a powerful stun spell directly at the hidden location, followed by a violet spell from Lupin.

The two spells struck the ground with a resounding thud. William didn't even flinch; he simply rolled over with Harry, landing amidst the blasted and falling dirt and the unabsorbed rainwater.

Without thinking, he immediately cast a spell into the air.

A firework-shaped spell rose directly into the air—Hogwarts was right next to them, and it was the first day of school. As long as he could keep Sirius's attention focused, there was no need to worry about anything going wrong.

"William, is that you?"

Hagrid's voice came from afar, sounding calm.

"Hagrid, find cover, then check the surroundings for enemies!"

William shouted anxiously, then added in a loud voice, "Everyone stay in the car and wait for the professor to arrive!"

His orders were carried out, and the Hogwarts Express arrived quietly, unlike its usual noisy arrivals, until a trustworthy person Apparated into the station.

“Alright, it’s safe now,” Dumbledore’s distinctive voice echoed through the crowd. “Everyone can get off the train now.”

Like water droplets falling into a pan of boiling oil, the Hogwarts Express was immediately erupted in cheers.

All the students began to cheer. For a moment, the Hogwarts Express was like a motorcycle in India, with no one able to guess how many students would be able to join it.

William breathed a sigh of relief and, together with the wary Lupin, emerged from the depression and then lifted the still-unconscious Harry.

The two of them were under the most pressure just now—after William revealed their location with his loud voice, Sirius's primary targets were definitely the two of them and Harry, who was being protected.

"Thank you, Professor Dumbledore."

William used his wand to lift Harry up, then looked at Dumbledore with a smile. "You're here even earlier than I expected... To be honest, I'm really not good at protecting people..."

“No, you are too modest, Professor William,” Dumbledore said with a smile. “He has been well protected, hasn’t he?”

That's true. Although Harry was covered in mud and water, he was perfectly fine.

As for the others—those that the school doctor can cure are not considered major problems.

“Sirius Black…” William glanced around. “To my surprise, he’s actually scared. Is it because we’re too close to Hogwarts?”

“It’s hard to confirm…” Dumbledore shook his head, a rare occurrence for him.

“Fudge sent me a notification that a group of Dementors have completely broken free from the Ministry of Magic’s control.”

“Out of control…” William shook his head. “It’s not just that, Headmaster, they’re completely under Blake’s command…”

"This is a problem. What's puzzling us now is how exactly Black controls those Dementors?"

“God knows,” William said with a rare wry smile, “What I fear most right now is those guys in Azkaban… If Black takes control of all the Dementors, then Azkaban is bound to have a mass breakout…”

This was not good news—as a prisoner who had come out of there, William knew very well what kind of people were imprisoned in the deepest parts of Azkaban.

Individually, they aren't as troublesome as Blake, but if they escape together, then Blake won't be a big problem...

Those were dark wizards who had been imprisoned for over ten years and had fallen into a state of near-madness... They were terrifying enough when they were normal, but when they went mad...

“Fudge has already urgently dispatched strikers to Azkaban,” Dumbledore smiled at William. “No need to worry too much, Professor William. The breakout hasn’t even started yet, and the Aurors are still here.”

"Are you sure, Minister?"

In Fudge's office, his assistant asked cautiously.

“If I’m not sure, I’m doomed…” Fudge scratched his head in anguish. “The Dementors attacked the students—and I was the one who sent them!”

"Either I admit I sent them, or I declare them out of control... I believe many people would prefer to hear the second answer; they wouldn't mind losing a bunch of Dementors."

“We can think of other ways… Minister…”

"What method?"

"We claim that those Dementors...want...no, they were originally normal, but were affected by something special, which is why they went mad!"

"What special effects?"

Those were half a squad of Dementors, obedient and useful henchmen, whom even the Minister of Magic wouldn't use as toilet paper.

"For example, Harry Potter!"

"They were just patrolling, but they sensed Harry Potter! So they became agitated—doesn't some book say that Harry Potter is the savior?"

The assistant quickly summarized the situation, "Harry Potter is the savior, he himself is a walking Patronus. The reason those Dementors are so crazy is to destroy that human Patronus who is even more powerful than the Patronus himself!"

"Didn't the Dementors say that Harry Potter reacted strongly to them too? Those two professors must have been protecting Harry Potter! As long as all the Dementors react strongly to Harry Potter, then no one can question it!"

The assistant editor's explanation became increasingly perfect: "That's it, otherwise how did Harry Potter defeat the Mystic?"

“Everyone will believe me… I will handle all of this, Minister.”

"Okay, we'll do it your way."

Fudge grasped at this like a lifeline. “Tell me when you’ve dealt with it, and I’ll write to Dumbledore again and announce it publicly.”

-

"Are you alright..."

"Um…"

Can I have your hand?

"..."

Various conversations took place among the students—Dumbledore's arrival dispelled their fear, but the chilling feeling of being surrounded by Dementors lingered.

When faced with a single Dementor, people can use their courage to defeat it and not be disturbed by its negative emotions—although this is difficult, some people can do it.

However, resistance is not very effective against hordes of Dementors.

Even the Ministry of Magic's top fighters were defeated by hordes of Dementors—they were among the best graduates of recent years, but unfortunately, Hogwarts' magical self-defense techniques...

The Patronus Charm is no ordinary spell; it's one of the most difficult spells available. Given the less-than-ideal teaching methods at Hogwarts, strikers had virtually no advantage when facing Dementors.
