Not to mention the annoyance in Albert's heart, Allen's side also dispersed.

Ms. Maxim put her arm around Fleur's shoulders and led her out of the room. Alan could hear the two of them discussing their candidates in French as they walked towards the auditorium.

Karkaroff greeted Krum, and they left without saying a word.

"Harry, Alan, I'm sure the Gryffindor and Ravenclaw classmates are waiting to celebrate with you. Go ahead!" Dumbledore said, smiling at the two of them.

Harry followed Alan and left the small room.

The Great Hall was now empty, and the flame of the candles was already low, which made the jack-o'-lantern's grinning grin seem flickering and eerie.

"Allen...... Although Alan made Harry very warm before, whether it was the estrangement of the last semester or the growing gap between Alan and himself after he grew up, it has made it impossible for him to communicate with Alan as naturally as he did a few years ago.

After saying goodbye to Harry, Alan quickly returned to his dormitory, changed into clothes that were easy to travel, turned into a phoenix, and apparitioned, and came to the periphery of Azkaban.

It's an eerie and lonely island with an air of despair.

The ground was foggy, and behind the gray fog that gradually diffused, a castle stood in a black hole.

Alan turned to look at the oppressive prison with anticipation in his eyes if his vision could come true......

Alan looked up at the sky, there was no moon, no twinkling stars, only a deep black.

Eren hid his form, covered his cheeks with a mask, and made his way quickly across the empty island.

The fog was low, clinging to the dull meadows, churning over the pavement, but there was no wind here, and the air was completely still.

Soon the fog began to rise, and it enveloped Allen, flooding the castle in the distance, engulfing everything with a thick, haunting gray.

Alan didn't intend to go deeper, he cautiously thought about the direction of the castle to get closer.

Gradually, two figures appeared in the mist. A dark gray shadow drifted towards Alan, and stopped where he could be seen through the mist.

Dancing black figures loom or disappear in the floating mist.

"Dementors. Not only did Eren not dodge, but immediately turned into a phoenix and quickly approached them.

The mist puffed up again, sinking towards the meadow and flowing elsewhere.

The two Dementors surrounded Allen.

Alan grabbed the two Dementors with lightning speed.

The moment he touched the Dementor, Alan's eyes went dark, as if the light around him had been absorbed by the Dementors, Eren seemed to have fallen into boundless darkness, courage and hope faded, and nothingness gradually took over his heart.

Perhaps they had never been approached so close by a living being, and for a moment the two Dementors were stunned.

By the time they came to their senses, they had found themselves in a room with a pentagram of stars drawn with silver threads.

Alan's wand slid into his hand and pointed at the Dementors, and a silver phoenix flew out from the tip of the wand, circling around the Dementors, driving them to the pentagram made of Mithril to activate the Imprisonment spell, and the walls gradually emitted a silver light, and the light became brighter and brighter, converging from all directions into the pentagram in the middle, and the pentagram was shining brightly, firmly binding the Dementors in the circle.

It was only at this time that Alan felt that those joys and happiness were gradually returning to him, and he couldn't help but breathe a sigh of relief.

According to Albert's memories, Dementors usually patrol alone, and this time Alan encountered two Dementors at once, which was really unexpected by him.

If you don't use the Patronus Charm, even with Allen's strength, it would be very dangerous to fight the Dementors alone.

Despite this, Alan was very satisfied with himself, and although the trip was not quite what he imagined, he managed to capture the two Dementors without making a big fuss.

They waved their arms to rush out, their blackened, withered hands sliding across the light curtain, stabbing and sparks flying, and they were bounced back by the edge of the light curtain and fell to the ground.

Eren upgraded the strength of the restraints, and the white pentagram of starlight gathered on the bodies of the two Dementors, who were immediately frozen in place, paralyzed and unable to move.

"It's funny. Alan put his hand on his chin, he was a complete Ravenclaw, he couldn't care about being tired, and Allen's attention was on the Dementor again, the Dementor knew very little, and there were many rumors, Alan couldn't wait to start researching it.

Alan cast a petrification spell that hit the Dementor on the left, but the spell went like mud and rock, and the Dementor didn't react at all.

It was also the first time that Eren had used the Bondage Formation. This formation is essentially a prison circle, it is different from ordinary magic, it only reduces the activity space of the creatures in the array, in essence, it is not to imprison the creatures but to change the space environment in the circle.

While Dementors cannot be paralyzed by the Petrification Charm, the Binding Formation is effective against Dementors. The Binding Formation reduced the space in which the Dementor could move to the extreme, as if it were locked in a small box, immobilizing him.

Eren started with a simple petrification charm and slowly leveled up, even the dark magic he knew, all on the pitiful-looking, helpless, but terrifying Dementor.

But as a result, without exception, these spells had no effect on it.

Loosening the formation slightly, giving the Dementors some room to move again, Alan paced back and forth in the room.

He glanced at the other Dementor and finally made up his mind: "Avada suo." A green light went straight at the Dementor, and to Alan's surprise, the Dementor did fall after being hit, but it didn't take long for it to return to normal again.

Could it be that the only thing in the world that can deal with the Dementors is the Patronus Charm? Alan did not give up, and a dementor thought went straight to the Dementors.

In an instant, a multitude of complicated thoughts came flooding his mind, and Alan stopped holding his head.

These thoughts are very chaotic, and they are full of malice, and they are extremely vicious, which is why Alan feels a headache.

Alan imprisoned the two Dementors once again and brought a set of dissection tools from the Black family's collection.

At the same time, Alan decided to look for information in the book, and then further study the Dementors and why they were so weird.

Anyway, he is now a warrior of the Three Witches Tournament and does not need to take the final exam. Alan decides not to go to class the next day and devote himself to studying Dementors.
