Felix noticed Hermione's sight clearly.

"Oh, those are indeed black magic books, but what do you mean? If you want to defend against black magic, you must have a certain understanding of it. As far as I know, the Aurors in the Ministry of Magic will teach some black magic specialize in."

"But I rarely see..."

"Some wizards don't use black magic, but that doesn't mean they don't know how to use black magic."

Felix smiled gently at her, "I have been traveling around the world for a year, and I have to mention that when solving certain problems, black magic is indeed more effective."

Hearing Professor Haypu's explanation, she quickly thought about it and felt that this reason was barely acceptable, but she still said with a stern face: "Professor, I still recommend that you use less black magic in the future. I have read in a book: black magic always quietly invades your heart, causing you to be corroded unconsciously-"

"——Many young wizards are on the wrong path, especially for underage wizards, black magic is an inconsistent psychotrope." Felix said in the words of Hermione.

He blinked, "I have read this book, too."

"But, thank you for your advice."

Hermione pursed her lips, looking very much like Professor McGonagall.

Seeing his assistant being a little angry, Felix changed the subject without a trace, and praised: "I didn't expect that you had read so many books. At your age, it was a very amazing achievement."

Following the professor's gaze, Hermione discovered that the other half of the room - with the small table as the dividing line, and the side close to her - turned out to be a completely different decorative style.

The warm sunshine shines large areas of light, the light brown carpet and goose yellow curtains give people a very comfortable feeling. There is a small round table in the center, and two pots of green plants are placed on the table.

On the wall opposite is a floor-to-ceiling bookshelves. There are hundreds of neat books placed inside, from the top to the bottom, seven or eight photo frames stand, including photos of the family and photos of Hermione since she was young.

Close to the bookshelf is an ivory door.

Hermione covered her mouth in surprise. This half of the space was actually similar to the room at her house.

She turned her head and looked at Professor Haip, feeling full of doubt. Now only this professor can solve his doubts.

Professor Haypu indeed gave the answer, "This is the world of thinking and the residence of fantasy. You can call it anything. Of course, all this is not true, we just have consciousness here."

Hermione was amazed. She stood at the junction of the two spaces, staring at the left and right, and she waved her hand hesitantly, "So, is this place built by us together? Half represents your inner world, and half represents my inner world..."

Felix pointed to his head, "It is just a part of the external mapping and projection of our inner world."

"And the deepest secrets in our hearts are all behind the door." He first glanced at the ivory door, then waved his wand, and the dark green curtain behind him rolled up high, revealing a tall door.

Hermione obviously relaxed, but she had many secrets and was unwilling to reveal them easily.

For example, Harry's snake accent.

"Professor, why do we come to this... world of thinking?"

Felix did not answer directly, but introduced some of his experiences first. "After graduation, I spent a year traveling around the world, and then settled in London, specializing in Muggle research."

"Muggles' wisdom is no worse than wizards. They are better in many aspects, such as logic, reasoning, and methodology for solving problems. And the more important point is inheritance."

"They will pass on their knowledge and accumulate from generation to generation, causing qualitative change from quantitative change."

"Witches also have inheritance, such as Hogwarts, but they are far behind in inheritance and development."

"It was realizing this that I started reading Muggle books. To be honest, I got used to moving photos, and I was really not used to reading Muggle books."

"Their research on thinking and brain caught my attention, and I found that they have come to the forefront of us in this regard - and this should be the realm of wizards better - after all, we have a series of memory magic, like forgetfulness, mindfulness, and brain closure."

"But unfortunately, we have inherited only the mantra, not the idea."

"So, I combined the knowledge of Muggle and created a magic that, although it is still quite far from what I expected, is perfect for our teaching today."

"What's the use of this magic?" Hermione asked curiously.

"Thinking speeds up," Felix explained, "here—I call it the Thinking Hut—your thinking speed will speed up, and with this place we will have the illusion that time is being stretched out. I can only increase it three or four times, and it will be dangerous if it is higher."

"Similar to this magic is Bafe's brain-waking potion, but the performance of the two is not exactly the same, and the latter can enhance the mind power of the users."

Hermione's eyes widened, "Professor, this magic is really amazing."

Felix shook his head, "It's not perfect yet."

Seeing that the professor was reluctant to say more, Hermione began to practice portraying ancient magical texts. She used the chestnut chips provided by Felix to her - this is also one of the disadvantages of this magic. If you cannot understand it, you cannot appear here.

Most of the time, Hermione practiced herself, and Felix gave him some guidance every once in a while.

After seven thoughts.

Felix noticed that Hermione's face was covered in sweat, her figure became increasingly light, looking a little like a transparent ghost.

"Professor, I can't concentrate, I can't keep my attention..."

"Well, it's almost time, so let's be here today." Felix snapped his fingers, and the next moment, the sky was dizzy, and the two of them returned to the lounge again.

Felix's wand was still on Hermione's head. He was originally still and suddenly staggered and almost fell to the ground.

He pressed his forehead with one hand and waved his wand with the other, and a bottle of potions flew out of his suitcase.

Under the command of the magic wand, the potion bottle was quite conscious. Not only did it open the lid itself, but it also called two cups and poured out some of the potion.

On the other side, Hermione was in a bad mood. She fell directly on the sofa, her face full of pain, as if she was about to faint in the next second.

"Drink it and it will relieve your symptoms."

Hermione forced herself to drink the potion.

"Eat a piece of chocolate." Felix gave her another piece of chocolate.
