Witcher at Hogwarts

"Where's my wand!" Ron shouted loudly from the side, "Who can use the wand to cast a flashing spell! It's really dark here and I can't see anything!"

"Hey!" Hermione's voice suddenly came from the darkness! "Someone stepped on my foot! Take your foot off!"

"Sorry! Hermione!" Neville's voice came out from the darkness again.

"What? Neville?" Ron asked confused, "When did you come?"

"I'm just here to see you." Before Neville could finish his words, a sharp scream suddenly came from the carriage, startling everyone.

"What's going on? What happened?" Harry asked in a panic.

Harry's nerves were so tense at this moment that he even thought that Sirius Black had sneaked into the train.

"It's my fault! It's my fault! I accidentally sat on a cat!" Neville said.

"Mountain Brook!" Hermione screamed in the darkness and went looking for her cat.

"I'm sorry! Hermione! No matter what happens, I will compensate you with a new cat!" Neville said apologetically.

Ron's snickering voice seemed to be heard in the darkness.

Suddenly, a big ball of light appeared in the corridor, and Ethan appeared in front of everyone holding a wand.

Behind Professor Ethan stood his strange assistant teacher, Mr. Sirius White.

"Is Harry okay?" Mr. White asked urgently as soon as he arrived at the carriage.

Harry really couldn't figure out why this strange professor cared so much about him, so he had no choice but to raise his hand.

"I'm okay, Mr. White," Harry shouted.

Sirius Black finally breathed a sigh of relief when he saw Harry safe and sound.

"You all go in! Lock the carriage door!" Ethan said sternly to the students standing in the corridor.

"Harry! White! You too! Get in the carriage quickly!" Ethan urged Harry and Sirius Black.

Harry and Black obediently ran into the carriage and locked the latch on the door.

"Professor Ethan, what happened?" Hermione asked nervously while lying on the glass of the carriage.

"Dementors are searching the carriage!" Ethan briefly told Hermione the situation.

"Professor Lupin, please take good care of them!" Ethan warned the man in the box.

At this time, the little lions in the carriage remembered that there was a professor in their carriage.

At this time, the sleeping professor also stood up at some point. He also held up the wand, and the tip of the wand flashed bright light, illuminating his tired and gray face.

But his eyes were particularly alert, and he was looking around alertly.

"Okay, Professor Ethan, I will protect them." Lupine assured Ethan in a hoarse voice.

Sirius Black looked at Lupine with a somewhat complicated expression.

As soon as Lu Ping finished speaking, the surrounding environment changed.

First of all, the surrounding temperature dropped rapidly, and several people in the carriage found that even their breath began to appear white mist.

An unprecedented chill permeated everything around them. The biting cold penetrated their thin clothes and seemed to have frozen their whole bodies.

The windows of the carriage were gradually covered with frost flowers.

"What happened?" Neville's voice was trembling.

As if in response to Neville's words.

A monster wearing a black gauze-like cloak, as tall as the ceiling, slowly appeared in the corridor.

Everyone couldn't see his face clearly, but they could all feel that this terrifying chill was emanating from this monster.

Harry found that Professor White, who was standing in front of him, was shaking violently, as if he was very afraid of this monster.

But even so, he still stood firmly in front of Harry, showing no signs of escaping behind.

This made Harry even more confused.

Everyone also discovered that Professor Ethan was standing in the corridor at this time, blocking the path of the terrifying monster.

Ethan stared closely at the Dementor in front of him, stretched out a hand from the Dementor's cloak,

The hand looked like a corpse, gray, thin and scabbed, a bit like the hand of the water ghost in Ethan's world.

"I am the leader of the Magical Crisis Response Team of the Ministry of Magic. The safety of this train is now under my protection. I can ensure that there is no Sirius Black on this train. You can retreat."

The dementor didn't seem to hear what Ethan said, and kept walking forward.

"I'm warning you one last time, stop moving forward! Otherwise I will take necessary measures!" Ethan lifted up his coat, revealing the Ministry of Magic badge on his chest, and showed it to the Dementors.

The Dementor still went his own way, drifting towards the last carriage, as if there was something in that carriage that was attracting him.

An imperceptible smile appeared at the corner of Ethan's mouth. He had not expected these dementors to be obedient. His so-called two warnings were just to make his next actions more "legal".

At this time, the Dementor had already passed Ethan and began to try to open the door of the carriage where Harry was.

Sirius, who was standing in front of Harry, had a look of despair on his face.

"Aden" Ethan's hand quickly drew a rune on the ground.

In an instant, a circle of purple-red runes appeared on the ground with Ethan's rune as the center point, including both Ethan and the Dementor.

Despite her horror, Hermione watched the corridor carefully.

She was very worried about Professor Ethan. This terrifying monster seemed very difficult to get along with.

The dementor's body, which was still ethereal just now, became much "thicker" the moment it was covered with runes.

Then a shocking scene occurred. Ethan directly grabbed the dementor's neck, which was supported by dry bones, from behind.

He lifted the dementor up high and then dropped it heavily to the ground.

The dementor's materialized body fell heavily to the hard floor of the corridor, letting out a short and rapid scream.

At this time, the dementor was also a little confused. It had never been treated so roughly before. In the past, it always walked sideways in Azkaban.

No matter how cruel and evil the criminal is, after entering Azkaban, he always looks fierce at first.

But after being tortured for a long time, they will turn into a puddle of mud, collapse on the ground and beg for mercy.

This was the first time it had experienced being thrown to the ground so hard today.

After a brief period of confusion, the dementor became angry and let out a dry and unpleasant roar.

He wanted to get up and suck the guy who had thrown him to the ground, just like he usually tortured the prisoners.

But what awaited him was a more brutal blow.

Ethan's hard boots ruthlessly stepped the Dementor that was about to fly back to the ground.

The dementors tried to fly many times, but they always got the same ending.

Although the Dementor couldn't feel pain, this huge feeling of humiliation still made him howl angrily.

The sharp and piercing scream made Ethan frown, and at the same time, the scream also attracted the attention of other dementors.
