Witcher at Hogwarts

"Okay! Stop arguing!" Ethan said impatiently, "Hurry up and complete the unbreakable oath!"

Dobby shrank his head and stopped talking, and Sirius also held Ethan's hand together.

Dobby held Ethan's wand and lit it on their clasped hands.

"I, Ethan of Toussaint, will bring Peter Pettigrew to Sirius Black to help him prove his innocence."

"I, Sirius Black, am willing to be loyal to Ethan in a personal name after he fulfills his promise to Toussaint, as long as he does not do anything to harm Harry Potter."

A thin, dazzling tongue of fire spurted out from the wand, like a red and hot metal wire, wrapped around their clasped hands.

The unbreakable oath was thus established.

"Now! Now! Go and catch that bastard Peter!" Sirius Black, who had completed the Unbreakable Vow, couldn't wait to ask Ethan.

"I promised to help you catch Peter Pettigrew and prove your innocence, but I didn't say when!" Ethan said casually.

He wasn't going to break his promise, but he didn't want to catch Peter Pettigrew so quickly.

Sirius Black's escape from prison ignited a fire in the peaceful Ministry of Magic, and Ethan planned to use this fire to burn it out.

Only when the fire burns big can you highlight your own value by putting out the fire. What's more, when the fire starts, some villains with ulterior motives can jump out.

Ethan plans to use these to write some articles.

"You bastard!" Sirius Black jumped up angrily, planning to fight Ethan.

"You are not allowed to hurt Mr. Ethan!" Dobby screamed from the side. He waved his hand suddenly, and Sirius Black flew out and landed heavily on the ground.

"Calm down! Blake! Look at what you look like now! You are no different from a corpse!" Ethan yelled.

"You should cultivate yourself here, take good care of yourself, and don't act recklessly. After all, you will still be Harry's guardian in the future." Ethan said softly.

"Harry's Guardian" seemed to have injected some energy into Sirius Black, and he finally settled down.

"Give me some food and drink, I haven't eaten anything normal for too long!" Sirius Black said to Ethan in a hoarse voice.

Ethan left a lot of wine, meat, food, and medicine for Sirius Black, and used magic to repair the cabin so that it no longer leaked.

Ethan used magic to create some furniture, a soft bed and a bathtub.

He also asked Dobby to take good care of Sirius Black. Although Dobby was very reluctant to take care of him, he still agreed to Ethan's request.

This cabin is in a deserted grassland, and no one usually comes here. Ethan has cast a lot of shielding magic around it, so the cabin is very safe.

"Black, take good care of yourself. You will be able to live with Harry soon!" Before leaving, Ethan comforted Sirius Black again.

Sirius Black huddled in the corner of the cabin, hugging his knees and nodded.

Ethan walked out of the cabin, Sirius Black's matter was resolved, and his plan was more than half successful.

Ethan stayed at the Weasley house for a few more days and used these days to train Harry and Ron.

On a gloomy day with stormy weather, Ethan planned to undergo his first Animagus transformation.

After some extremely tedious preparations, Ethan finally figured out all the steps for Animagus transformation.

The Weasleys were very surprised when they learned that Ethan was going to undergo an Animagus transformation. They asked to watch Ethan's transformation as if it was some kind of ceremony.

Ethan chose the transformation location in the backyard of the Weasley family. He held the finished blood-red potion in his hand and swallowed nervously.

Most Animagus transformations performed by wizards in this world are ordinary animals, but Ethan comes from other worlds, and he is also very curious about the animals he will transform into.

Ethan pointed the tip of the wand to his heart, chanted the incantation "Amado, Animo, Animado, Animagus", then raised his head and drank the blood-red potion in one gulp.

Ethan tried hard to calm his mind and feel the condition of his body. He tried hard to recall the key points of transformation and waited for the changes in his body.

Suddenly, a sharp pain exploded from his back, and another heavy heartbeat sounded in his chest.

Ethan, your mind suddenly recalled the first monster Vesemir took him to hunt.

A male griffon attacked a horse farm and killed many good horses.

The owner of the racecourse hired a witcher to destroy the gryphon.

That griffon was the first monster Ethan killed alone, and he left a deep impression on Ethan.

Its feathers are as smooth and shiny as a knight's shining armor, its cry pierces the sky, and its claws are as sharp as a razor. It is a perfect opponent.

Ethan fought with him fiercely for a whole afternoon before he defeated the gryphon. Ethan gave the respectable opponent a happy and neat death.

To prevent it from suffering, Ethan cut off the griffin's head and collected the bounty. From that moment on, Ethan officially became a demon hunter.

At this time, Ethan's mind was filled with images of that heroic gryphon.

Ethan felt that every muscle in his body was being torn apart, and every nerve was being violently twisted and pulled.

Two huge wings suddenly appeared on his back, and were quickly covered with black and gold feathers. The feathers were thick and the branches were dense.

"What is Professor Ethan going to become? An eagle?" Ron asked curiously.

"Shh!" Mrs. Weasley told Ron to be quiet. He knew that he could not tolerate any interruption during the transformation process.

Thick black and gold feathers quickly spread from Ethan's back to his whole body. His arms gradually merged with his wings, and sharp claws like long knives sprouted from the tips of his wings.

At the same time, Ethan's size also grew crazily, and his mouth turned into a long black beak that shone with cold light.

Ethan turned into a gryphon.

"Oh my god! What kind of animal is this!" Mrs. Weasley exclaimed softly, covering her mouth.

"Looks like a gryphon," muttered Mr. Weasley, "but I've never seen a gryphon like this."

The gryphon transformed by Ethan let out a majestic cry, flapped its wings, and rushed into the sky.

Ethan flew wantonly in the sky, and thick lightning exploded around him, but Ethan was not afraid at all, and he let out two clear screams.

At this moment, Ethan, who was flying freely between heaven and earth, was in an extremely happy and relaxed mood. He flapped his wings vigorously to speed up and traveled quickly through the clouds.

Ethan looked down and saw a strange-looking house below. Only then did Ethan realize that he had actually flown to Luna's house.

In order to show off, Ethan lowered his height, hovered over Luna's house, and let out a loud cry.
