My Hogwarts has a serious problem.

608 Queen Street, Lisbon, Northern Ireland.

Lynn stood in front of a very dilapidated two-story building and double-checked the address to make sure he hadn't gone to the wrong place.

This location is in the most secluded corner of this street.

The house had clearly been uninhabited for a long time. The iron fence around the yard was covered in rust, the front yard was overgrown with weeds, and the chain on one side of the swing in the yard was broken, with half of the iron plate buried in the weeds. It looked as desolate as a haunted house.

Lynn did not come here alone; he brought Kira with him.

Before learning Apparition, house-poms are undoubtedly the best tool. Although Kira had never been here before, it could take Lynn to a nearby city first, and then he could come by train or bus, which would save a lot of time.

Moreover, there was another purpose in bringing Kira along—to use magic in his place.

Lynn hadn't forgotten that before leaving school, he had signed his name on a Ministry of Magic pledge prohibiting underage wizards from using magic outside of Hogwarts.

According to Snape's explanation when they signed, this pledge was a magical contract. By signing it, they agreed to the contract, and the threads used to detect magic would naturally form on the young wizards.

If the contract is violated, you can refer to Harry Potter being brought to trial in the original work.

Lynn had used magic before in Abros, but at that time it was because the situation was urgent and there was more than one wizard with him. It was impossible to accurately detect who cast the magic, so it didn't cause any problems.

But when he was all alone, he dared not test the Ministry of Magic's ability to enforce the law.

Having Kira use the magic in his place is undoubtedly the safest option.

Even if the Ministry of Magic gets confused and mistakenly believes that he cast the spell, Kira won't run away like Dobby; it will testify for Lynn.

With a swift unlocking spell, Kira helped Lynn open the courtyard gate.

House-elves' magic is quite interesting. They are born with the ability to use magic without a wand, although the power and effects are somewhat weaker. However, because it differs from wizard magic, many restrictions are ineffective against them.

For example, Hogwarts' forbidden Apparition magic.

The rusty axle emitted a long, deep creaking sound.

Lynn walked through the weeds in the front yard, and Kira opened the living room door for him. Then he found a corner to enjoy his own little world.

Professor Fox estimates that he hasn't returned here since his release from Azkaban two years ago.

The furniture in the living room was covered in dust. Lynn ignored all the other odds and ends, but something on the living room cabinet immediately caught his eye.

It was a black-and-white magical photograph: a little girl was happily swinging on a swing, with her parents standing behind her, their faces beaming with gentle smiles.

They seemed to be a happy family.

Lynn gently brushed the dust off the photo, looked at it silently for a long time, and finally put it in her pocket.

Without wasting time in other rooms, he went straight to the study on the second floor.

Unlike the other rooms, it was locked, but there was no keyhole.

Following the method Professor Fox had taught him, Lynn gently knocked on the door and then spoke.

"It's hungry."

The door opened by itself with a "click".

Inside was a small study with only two simple rows of bookshelves, and the bookshelves weren't even fully booked yet.

Unlike the outside world, this place is not dirty and messy. There is special magic protecting this room, allowing it to withstand the erosion of time for a short period of time.

"Is there anything you need, sir?"

Suddenly a sound came from above; it was from an old-fashioned chandelier.

"I need to pack up and take the study with me." These were the exact words the professor had taught him.

"As you wish."

The bookshelves on both sides of the wall suddenly began to tremble, causing Lynn to instinctively take two steps back.

The bookshelf shrank until it became the same size as a primary school student's schoolbag.

They hopped and skipped from both sides to the desk in the middle, and finally joined together to become a black briefcase.

The chandelier on the ceiling then fell down by itself, landing lightly on the suitcase and turning into a metal clasp.

Lynn found everything before her extremely interesting.

He picked up his suitcase, closed and locked all the doors again, and then called out to Kira, asking it to Apparate and take him back to London.

After returning home, carrying his suitcase, Lynn went to the empty room he had prepared beforehand. He placed the suitcase on the floor and said softly.

"I need a study."

The metal buckle jumped up first, soaring high into the air until it reached the ceiling and transformed into an English chandelier.

The two halves of the suitcase also began to separate, finding their way to the wall and expanding against it until they were the same as before.

And just like that, Professor Fox's study was perfectly moved to Lynn's house.

Besides the rare dark magic materials, the two rows of bookshelves and the chandelier were also very valuable magical items, and all of these items, including them, were given to Lynn by the professor.

Their functions certainly don't stop there.

Lynn sat down at his desk, and a cup of black tea appeared out of thin air in front of him; Kira had brewed it for him.

"I need data on the spread of dark magic."

He spoke to the empty study.

As if he had heard the call, five or six books flew out of the bookshelves with a "whoosh" and landed lightly in front of Lynn.

None of the books had covers; they were called books but looked more like notebooks.

Lynn casually flipped through the notes; the contents were somewhat complicated and couldn't be understood in a short time.

He had anticipated this; if it were really that easy to learn, Professor Fox wouldn't have called himself an expert in dark magic.

He wasn't in a hurry. He put the notes aside on his desk, took a sip of tea, thought for a moment, and then spoke to the study.

"I want an interesting book."

The bookshelf swayed for a long time before finally selecting a book and floating down to Lynn's side.

It was a book with a green cover and a lifelike white ghost printed in the center of the cover.

Unlike those notebooks, this book has its own title—"Exorcism: Soul Capture".

Lynn was immediately captivated by it. He opened the book and began reading from the first page.

An afternoon passed quickly. Lynn closed the book, his brow furrowed. He wasn't troubled by the curse recorded in the book, but rather by the inspiration it had given him; he suddenly had a plan.

A somewhat daring plan, but with the potential to succeed!

To provide evidence of the possibility of his plan being implemented, Lynn immediately wrote a letter to Professor Fox.

After he finished writing the letter, he realized that he was no longer at Hogwarts and there were no public owls for him to borrow.

Lynn poked his head out expressionlessly and glanced at Umaru, who was sitting happily on the sofa, munching on a meat pie made by Kira while watching TV.

So what's the point of keeping a lazy, gluttonous hamster?

Looks like it's time to get a new pet.
