There was a long list of "for example" behind it.

Felix estimated that any normal person would be tempted by one or two of the above-mentioned contents, provided that they could really be realized.

At the bottom of the flyer was a simple map.

Felix became even more curious. The person who handed him the flyer was obviously an ordinary person, but was it an accident or a coincidence that he went straight to him? He felt that it was more likely that someone was doing something secretive in the name of magic. As for what it was specifically, he decided to go and see.

Felix followed the instructions on the flyer and crossed the remote streets. This hand-painted map was very "featured", with hidden marks drawn at the corners of each street, which required some thought. Felix

stood in front of a wall, staring at the graffiti on it, and looked at it for a while with the help of the dim street lights, and then turned left according to the guidance of the big rat holding a vertical sign in the graffiti.

There were no lights here. The shops on both sides of the street were shabby, and there were a lot of abandoned garbage on the corners. The only light kept flickering, and with the whimpering cold wind, it felt like a horror movie set.

But if Felix wanted, he could create the most realistic horror, and vice versa.

'Three people were looking at me in the dark along the way. There was no trace of magic, and the bad feelings in their emotions were not strong... just for money?' Felix walked slowly. Since it had nothing to do with magic, and it was not a dark wizard fishing, his interest in the end of the road quickly decreased, and he stopped from time to time to admire the graffiti on the walls along the way.

If you have to describe it, this is the necrotic tissue of the city of London, forgotten by the city hall, and ignored by several plannings. In the end, it became a paradise for wild cats and dogs, and it was also the favorite place for those 'rebellious young people'.

A few minutes later.

Felix pushed open a shabby door and walked in. The simple map on the flyer had long since lost its function. He found this place because of the movement of people and the magic circle painted on the door.

Judging from the window and the mottled sign at the door, this should have been a clothing store before. However, the sign said "House of Magic" in graffiti-style font.

Felix had a bad feeling. No wizard group would do such a thing. This place was more like something imagined and tinkered with by some occult enthusiasts on the street.

I was not fooled...

At this time, two burly men came towards him. They were the type who were better at communicating with fists. Felix sighed, and silver light flashed in his eyes. "Bang! Bang!" They fell to the ground without a sound.

After a few minutes, the few people who came to help did not run away.

Felix searched the abandoned hut. The thick layer of dust in the house showed that the original owner had left for a long time. His expression was quite disappointed.

"A robbery gang... maybe kidnapping and extortion?"

This was the information Felix got from these people's minds, which disappointed him greatly, especially when he knew that these leaflets came from a nearby trash can. It was a double blow. The truth was outrageous.

This

was once a secret base of a mysticism enthusiasts' club. It might have been disbanded due to the coming of winter or other reasons. Those leaflets were thrown into a nearby trash can and happened to be used by these passing robbery gangs: they found familiar words on the leaflets (dizzy, floating, not knowing where they were when they woke up...), and they all agreed that this description was very consistent with the effect of taking some "painkillers", so they highlighted this sentence and used it as a tacit code on the street to attract people in need.

Including when Felix talked to the drug addict, they all got this hint. Unfortunately, Felix didn't notice it at all, but was attracted by the word "magic" on the leaflets, so this group of people was in trouble.

"I was actually excited when I saw the two occult symbols at the door." Felix said dissatisfiedly, feeling that he was completely wasting his time. He should be in the warm office of Hogwarts now.

"What is the emergency number...999?"

Felix suddenly heard footsteps coming from a distance and stopped outside the door.

"Is anyone there?" a young voice asked.

Felix blinked, opened the door a narrow gap, lowered his head, and just met a pair of gray eyes. The owner of the eyes was holding a flyer in one hand and a wooden stick in the other, looking at him timidly.

Simply judging by his clothes, Felix estimated that this person was not in the same group as the previous gangsters. In fact, he looked even more terrifying in the eyes of the other party, which could be seen from the shaking hand.

"Is there anything wrong?" Felix muttered from his throat.

He wanted to get rid of the man in front of him as soon as possible, and then make an anonymous call to the police... Well, maybe he could wait until tomorrow morning. I heard that sleeping on the floor is good for the waist.

"Hello, is this the House of Magic?" the visitor asked cautiously, and the trembling hand raised the flyer in his hand. When Felix shifted his sight from the flyer to the wooden stick, the hand holding the stick immediately disappeared in front of him. Unless Felix stuck his head out, he would definitely not be able to see it through the wall.

The visitor smiled awkwardly.

"What do you want?" Felix asked again with a dark face and raised his voice.

"I, uh... I saw the flyer, which said that it can fulfill a wish of the members..."

Felix was stunned, turned his head to look at the ruins of the house and the fugitive sleeping on the ground like a dead pig, and turned his head to say sincerely: "You are so lucky."

"So, is it true?" said the excited voice.

Felix saw a pair of hopeful eyes, he smacked his lips, and his attitude became a little more serious: "So? I suggest you finish your words at once..."

A trembling hand was handed to him. "I... I practice piano. My hand was injured in an accident. I hope to play the piano again."

Felix looked at the uninvited guest in front of him. This person was sentenced to death by science, so he turned to, or placed his hopes on, mysticism?

To be honest, he didn't think this was a smart move. Most wizards would consciously abide by the confidentiality law and rarely deal with ordinary people. Among the few exceptions who had no scruples, dark wizards accounted for the majority.

However, the sudden appearance of the visitor in front of him made things interesting. Maybe it would become a day worth remembering. Felix thought.

So he said, "Your idea is not impossible to realize... But magic, as you should be able to guess, is very costly..." He deliberately said in an obvious mercenary tone.

"I brought money," the man said hastily, and in order to avoid looking like a sucker, he added cautiously, "I only brought one-third. If you can really fulfill my... wish, I will pay you the rest."

"Money is useless to me. For wizards, many things are more important than money. You have..." Felix said in a low voice.

"You want my eyes!?"

Felix rolled his eyes, "I hate this kind of horror story, it's full of groundless imagination... I have one myself, and I have one more than you." He suddenly grinned and pointed at his forehead. A blue light bloomed from the middle of his forehead, and in the layers of blue halo, an eye slowly opened.

"Ah!"

To Felix's surprise, after the scream, the uninvited guest's eyes widened even more. He had no intention of running away. Instead, he kept asking excitedly: "What price do I need to pay, soul? Health? Appearance? Lifespan?"

"I'm not familiar with the devil." Felix muttered. He hesitated and said, "Come in."

He turned around, and a layer of bright silver light quietly covered the whole room. The ruins in the room and the piles of fugitives disappeared in front of him. The dusty floor turned into a red carpet. The broken stones and glass fragments flew to the ceiling and turned into small orange lights. The fugitives turned into green potted plants and were piled in the corner.

The tattered chair seemed to have been repainted. The back of the chair kept stretching and raising. Two pieces of clothing were quickly wrapped around the chair and turned into two armrests. Several clothing racks supported semicircular dark arches...

When the strange visitor came in, he saw a small concert hall with a piano standing in the center. Opposite the piano was an auditorium with only one seat, occupying the best position.

"This is, uh, wizards also like to listen to music?"

"Ha!" Felix laughed, and he suddenly had a black cloak on his body when he sat on the chair. The room was brightly lit but his face could not be seen clearly. Two silver lights shone from the hood. Felix said in a low and hoarse voice: "Are you ready to make a deal with the wizard?" "

What do you need, Mr. Wizard?"

"A memory, your best memory."

The man was stunned and said hesitantly: "I don't even know what the best memory is. There is only pain in the past six months..."

"It doesn't matter, your heart will tell me the answer. So... the deal is done?" Felix said, and he felt that he should have prepared a pair of bat wings and an arrow-shaped tail in advance.

But thinking of wings...

Felix suddenly wandered in the sky, and he thought of a good idea, maybe he could create a new flying magic creation, a set of flying wings. He always felt that the posture of sitting on the broom was a bit stupid, well, don't worry, go back and think about it and tell Remus.

"...Mr. Wizard? Do I need to sign anything?"

"What did you say?"

"It's a contract or something, a demon... I mean, the kind that wizards sign with ordinary people."

"No, am I afraid you'll default on your debt?" Felix leaned back in his chair and said nonchalantly.

...

The crisp sound of the piano rang out. The first few notes were a little jerky, which was the influence of the injured hand, but soon, the melody became coherent and melodious. Felix half-closed his eyes and tapped the beat gently. It didn't take long for him to frown. The style of the melody in front of him was completely different. This feeling was like the cold and sad moonlight suddenly turned into a high-pitched and passionate charge war song. Just after listening to two sentences, it turned into a gurgling stream and a low and solemn forest horn in the next second...

This was no longer music, but noise.

But the 'Contractor' played very happily, especially after realizing what the happiest memory was, he had already put all his heart and soul into the music, because after tonight he would lose this happiness forever...

Felix felt pure and radiant happiness, and the ability he gained from the Dementors allowed him to easily discover and distinguish these emotions. A golden vortex seemed to form in the yard, constantly expanding outward. Felix drew out his wand, gently rotated it, and collected some of the overflowing emotions. When the

magic power mixed with this precious emotion, a drop of golden liquid was formed.

His fingertips danced to the beat of the piano keys until the moon was covered by clouds and the sound of the piano was interrupted by the sobbing wind.

"Have a cup of tea, your hands are shaking from the cold." Felix said, and a cup staggered to the piano, and the liquid in the cup jumped with golden ripples.

"It's not frozen, it's just like this... What kind of tea is this? It tastes weird?"

Felix stood up and straightened his back. "Your music is unforgettable. I hope I can have a chance to see your official performance. So... the Magic House has to say goodbye to you. I wish you a good day." He waved his hand, and the person opposite him flew out of the house lightly as if he had no weight.

With a "bang", the door closed tightly.

"Oh, Mr. Wizard, you know that's impossible... Mr. Wizard? You haven't received your reward yet, where can I find you... Oh my God, why is the house gone! Did you do it, Mr. Wizard..."

The next morning.

This small house that was once full of miracles at night was surrounded by people. Two policemen led a group of fugitives out of it. They lay on the cold ground all night, with sick faces.

In the crowd, a head kept jumping and looking inside.

"What happened? Have you been caught, wizard? Who are they?"

Someone who arrived early said, "It is said that they are a very cunning group of fugitives. They were roaming around Surrey and committing crimes. I heard that they were discovered by a young man who came here to graffiti early in the morning and secretly called the police."

"Is that so..." The man was silent for a while, and suddenly raised his hand, showing off, "Uncle, look at my hand, are they still shaking?"

"Are you making fun of me?"

"Oh, sorry, I'm just too happy!"

...

In Hogwarts, in the Ancient Magic Office, Felix was talking to Lupin through the sound transmission mirror.

"There are only two things. One is the flying wings. The flying wings, you can name it whatever you want. I will make a sample in the near future. You can see how to improve and simplify it;"

"The second thing is to study the secularization of potions. There is no rush. Just compile a list of available ones for the time being."

"Secularization?"

"It means potions that can be used on ordinary people."
