When Harry and the others knocked on the door of Professor Happ's office, they heard a calm voice inside and said, "I get it, Felix."

The three of them looked at each other, "It's Principal Dumbledore!"

But when Professor Hayp opened the door, the room was empty and there was no one.

"Professor, President Dumbledore is here just now?" Harry couldn't help asking.

Felix smiled, "That's just a message from him, I'm not here." He stared at the knight doll in Hermione's hand and said hesitantly: "Why... is it there with you?"

He was not sure if the three of them knew something, and he complained in his heart, Sirius, you are too inferior.

Fortunately, the following conversation made him realize that they did not discover Sirius, but just sent him the magic puppet that he accidentally "lost". Hermione apologized for his naughty big cat, "Crook Hill may have used it as a toy. We cleaned it before we came..."

Felix stared at the Knight doll, its scarlet eyes flashing, sitting on a cup holder, and his back looked a little lonely.

“…Thank you.”

After the serious matter was said, Harry took out the nameless book from his pocket, "Professor Hayp, I have already chosen it, it's Phantom Transformation."

Felix was not busy refusing, but looked at him steadily: "Do you understand the risks of this magic?"

Harry nodded.

"Do you know how to solve the problem of splitting?"

Harinane was speechless. He looked at Hermione with help, and Hermione once again lived up to expectations: "If the separation is not serious, you can use white fresh treatment, preferably white fresh fragrance. If it is a more serious separation, such as the separation of the head and the body."

Harry looked at her in horror, but she continued to introduce seriously: "This situation requires professionals to deal with it. The information I found was the accidental event team of the Ministry of Magic."

Ron added: "There are fines. I mean if you find out that you don't have a certificate and get in trouble again, you'll be fined a lot of money."

Felix nodded slightly and said in praise: "That's almost all, so, Harry, do you still insist on choosing Phantom Movement?"

Harry said, "Yes, yes, professor."

Felix looked at him, "Don't worry, I have another question that you need to answer: When you know this information, what do you think is the most important preparation measure for practicing this magic?"

Harry opened his mouth, "Uh... ready for fresh white flavor?"

Felix laughed in silence, "This is the most basic. If not, I would doubt whether you have the blood of a troll. Think about it again!"

Harry frowned and scraped his stomach. Ron and Hermione were also thinking hard. Hermione's eyes lit up and she looked at Felix. Felix shook her head at her, and she put her hand down with some regret.

"I guess... I need someone to guide you?"

"It's very close, Harry."

Another minute later, "I understand! When practicing phantom shifting, you must be watching from the side to avoid no one to rescue you when there is serious separation!"

Felix smiled, "That's it. The most serious problem with phantom shifting is splitting. In the past century, there have been twenty recorded deaths. All of them are severe splitting when he tried phantom shifting in private. He was nailed to the spot and no one knew..."

"Their result is to watch themselves dry blood in regret."

Harry shivered violently. How did the professor say such terrifying words with a smile? The key is that it feels so picture-like. He is worried that the next time he faces Boggart, the object of fear will become a parted self.

"So," Felix turned his head to look at Ron and Hermione, "you will supervise Harry and not let him mess around, right?"

Ron and Hermione kept nodding, and they were also frightened by the serious consequences.

"Very good, let's talk about my arrangements." Felix said to Harry, "First of all, you have to master the theoretical knowledge of this magic first. I need you to write a paper about the shape of the phantom."

His fingers pointed at Wuming Book, and a bright silver light appeared on his fingertips. Various pictures began to appear on the Wuming Book page. They saw Professor Haypu's figures disappear suddenly and then suddenly appear.

"This book can help you, Harry. I set some restrictions that require you to crack them layer by layer. It's very simple, it's like playing a game. By the way, do you know what a game is?"

"Is it a TV controller game? It's included in Dudley's birthday gift a few years ago." Harry said that he saw it when his cousin Dudley opened his birthday gift and was envious of it.

But after a few days, Harry found a button on the handle in the trash can.

"Well, it's somewhat similar to the game level."

Felix continued: "The papers and cracking limitations are the first step you need to complete. The second step is practice. I will take you to train a few times until you have a preliminary grasp of this magic."

"You have to work hard on your own afterwards. Don't act recklessly. Make sure that someone is around you every time you practice. Do you understand?" He looked at Harry seriously.

Harry nodded in agreement quickly, and felt relieved. After hearing from the professor, he became very clear about what he wanted to do next.

"Professor, will we go to the Forbidden Forest to practice then?" he asked. "I heard that phantom shifts cannot be performed in Hogwarts. I have been imposed, uh, anti-phantom shifts spell."

Hermione nodded in agreement with Harry's words.

"No," Felix denied the claim: "There is a place to avoid this restriction."

Seeing that they wanted to ask again, he clapped his palms, "Okay, little guys, you will know then."

Finally, Harry tentatively asked about Professor Lupin's situation and was told that everything was normal.

When they came out of the office, Ron muttered, "We are not young anymore. In another half a month, I will be fourteen."

Harry said regretfully: "I have nearly half a year left," he said teasingly: "Ron, are you reminding us not to forget to prepare a birthday present?"

Ron blushed and chased Harry, trying to clamp Harry's head with his armpits. Harry ran away with laughter.

...

In the office, Sirius, who had changed back, sat on the sofa and said in a muffled manner: "Harry is too young. You shouldn't teach him this magic, you should be more cautious."

Felix looked at him with interest, "It really surprised me, you know the word "caution."

Sirius looked at him furiously and heard Felix continue, "Do you know Harry is learning the patron curse with Lupin?"

"What?" he asked in astonishment, "that spell to resist the dementor?"

Felix let a bottle of butter beer float in front of him, and Sirius poured her mouth into her mouth, "I miss it so much... I can't help but want to cry, life is still pretty good."

"You don't object?"

Sirius leaned against the back of the sofa and said lazily: "Actually, you have thought it pretty thoroughly, at least more than me. I just thought about it. If it were me, either refuse or take him to practice immediately."

"Knock!"

There was a knock outside the door, and Sirius choked by the beer in his mouth. He looked at Felix nervously, lip-syncing: "Come on the table, he just ate a piece, not sure if it was his helmet or his upper body armor, anyway, the knight sword had already entered his stomach.

"Professor Haip, it's me, Lupin." The voice outside the door said.

Felix looked at Sirius teasingly. Sirius walked to the door with a dark face, "Hey?" He pulled Lupin into the house.

"Bigfoot..." Lu Ping was stunned for a moment, hugged Sirius and said softly: "Forgive me, I have been misunderstanding you."

"Oh, Moon Face, please forgive me too..."

"Bear~!"

The two looked up and saw Felix fiddling with his wand, causing a fire to set fire in the fireplace. "The Floor Network line that was temporarily connected, if there is anything to talk about, if Harry kills a shot, the news of Professor Happ hiding the retaliatory crime will not be hidden."

Sirius grabbed a handful of Flourish fans and muttered: "You are jealous..." The next second, he was thrown into the fireplace, "You!#￥@%...No. 12, Grimo Square!"

Half an hour later, Felix and Lupin returned from the fireplace, and Lupin said thankfully: "Thank you for everything you do, Professor Happ."

"You're welcome, I'm also entrusted."

Before saying goodbye, Lupin couldn't help asking him: "When did you know I was a werewolf?"

"Why do you ask that?"

"You were not surprised when I said I was a werewolf before. If I couldn't guess, then I would be too stupid." Lupin said mockingly.

"It doesn't matter, so far, you're a good colleague."

When Lupin left, Felix sat on the sofa and said with emotion: "The long weekend...well," he pulled out his wand, and a swift guardian came out of the tip of the wand, "Go."

Half a minute

He whispered, "Severus, are your patron saints deer?"
