School hospital.

"Mrs. Pomfrey, I'll see Miss Hermione Granger," said Felix.

"Oh, she." Mrs. Pomfrey complained to him, "The little wizards nowadays are too troublesome. They abuse magic potions without any awe... In her case, they will have to stay in the hospital for at least three weeks."

Felix asked with interest: "Can you determine what drug is causing the impact?"

"It should be a compound decoction with cat hair. It's ridiculous. I don't know where they found the potion." Mrs. Pomfrey said, while pouring out half a cup of potion from the big bottle. "On Christmas night, when the two little wizards brought her over, I scared me. I almost thought it was irreversible magic damage."

"Compound Decoction..." Felix chewed the word, and after a few seconds he said to Mrs. Pomfrey gently: "Madam, I'll take her the way to bring the potion."

Felix pushed open the door and walked into the ward.

There were seven or eight beds in the room, but only one was covered with a white curtain. When Felix approached, the curtain opened from inside.

"Mrs. Pomfrey? Are you here to deliver medicine?"

A furry head poked out, and the sound was his assistant.

Hermione and Felix's eyes met and she froze.

"ah!"

The little witch screamed, immediately shrank back, pulled the curtain up hard, and the entire hospital bed trembled violently.

But just after a quick glance, he had already seen his assistant look now.

Her face was covered with brown cat hair, which mixed with her own hair, with a few cat whiskers on both sides of her cheeks, her eyes turned ginger, and two pointed ears on her head.

"Miss Hermione Granger, I heard about your experience from Porter and Weasley, and I came to see you." Felix said with a laughing tone.

He waited quietly for a few seconds, and from the curtain, Hermione's trembling voice came, "Hello, professor."

"I brought your potion, and-" Felix said, "if I don't mind, I can see if I can try to help you a little."

"Professor, are you saying...you can solve my trouble?" Hermione said in an expectant tone while hiding in the curtain.

Felix was still repeating her appearance in his mind, and he tried his best to maintain peace and said, "I can only say, try it, this is quite rare for you."

Hermione opened the curtain bit by bit, she raised her head and glanced at him quickly, then buried her face in her hands.

Felix placed the potion on the table beside him and carefully looked at the little witch's appearance at this moment.

This situation is really rare. Compound decoctions are difficult to cook. Even the potion master does not have much inventory, and they will not use it easily - the chance of such a mistake is even lower.

Hermione felt his exploratory vision and asked in a low voice, "Professor, do you have any solution? Mrs. Pomfrey said that a situation like me is very troublesome and will take at least three weeks to heal."

"Well, it was the wrong use of compound decoction, right?" Felix thought seriously. This situation was indeed difficult to solve.

He stretched out his wand and gently tapped on Hermione's forehead, and the tip of the wand emitted a golden light.

There was no change in the little witch's face.

"Well, the human body deformation technique is not good, it may have a conflict with the effect of the potion... It's really interesting, uh, I mean, it's really troublesome. So, try the unpopular spell."

In Hermione's eyes, Professor Happ was excited to cast spells, and he also took out a piece of parchment paper to record the effects of various spells.

"This won't work!"

"This is a bit of a useful thing, but not obvious."

"How about trying this?"

Hermione looked at Felix with a dull look on her face. Are you doing this to help me? I've seen through you, professor!

Finally, a rather uncommon curse worked.

The brown hair on her face quickly fell off and disappeared, and her skin reappeared and became whiter and clean. Hermione felt the change. She first touched her face, and then picked up a small mirror from under the pillow to check it carefully.

"Oh, my goodness." Hermione covered her mouth.

At this moment, her appearance changed a lot. Her original face was thick and lush brown hair disappeared, but the cat whiskers and a pair of pointed ears on her head remained tenaciously.

But this effect alone can surprise Hermione, whose mentality collapses, very much.

"Professor, what kind of magic is this?"

"A lightweight deformation technique can modify some small flaws in the body, of course, it is temporary, and the magic effect can last about two hours," Felix explained.

"Is it a human body transformed?" Hermione said with insight. She originally planned to learn this magic, but she couldn't help but feel a little disappointed at this moment because the human body transformed is a very difficult magic.

It's so difficult that even most adult wizards can't do it.

"It can be said that, but its effect may not be as good as you think - it can be modified in a very limited way. You should know that this spell was invented by a vampire and its original function was simply to cover up their fangs."

"Vampire?" Hermione asked with interest. The trouble that troubled her was solved more than half, and her attitude became much more lively.

"Yes, in the Middle World, everyone is calling for vampires. In order to hide in the crowd, they have developed this magic. But I have to say that the effect is really average, and it is incomparable to human deformation or disguise Magus. There is basically no one to use it now."

"Professor, I heard that disguised Magus can change his appearance at will?"

"Yes," Felix glanced at her, "this way you don't have to take the compound decoction at the risk."

Hermione lowered her head, and her pointed ears drooped.

"Professor, I..."

"You have made a compound decoction in private, right? I mean you, Porter, and Weasley three."

Hermione looked up and looked at Professor Happ in surprise.

"Yes," Felix said casually, playing with his wand, "this is easy to guess, especially when I think of you who asked me about special potions, I introduced six powerful potions in total, but you are obviously more interested in compound decoctions."

"Compound decoction can change the appearance of a person, and it can indeed obtain information without realizing it-"

"So, what I want to know is, who are your suspicions?" Felix looked at Hermione.
