"A wise choice, you will feel much better." Felix swung his wand, and a golden track spread between them, like snowflakes blown by the wind, and golden powder fell down one after another.

"Let's do a test first." He leaned back in his chair and looked at the golden rain curtain.

Harry also raised his head and fell into a hazy dream involuntarily. His mind was greatly relaxed, light and floating, as if surrounded by warm light. He felt like the golden powder flying in the air, becoming a part of them, forgetting any troubles... Harry subconsciously chased this feeling, but a voice in his heart told him that this scene seemed familiar.

What on earth was it? If he had had this wonderful feeling before, he must have been impressed, Harry thought intoxicatedly, his brain was like a rusty alarm clock, and every time the thoughts in his mind jumped, he had to stop and rest for a while, until Professor Moody's ugly face flashed before his eyes. It was too disgusting... This made Harry, who was immersed in the ocean of joy, sober up for a moment.

Why did he think of him? Was it because he was tortured by his class and fell in love with him? Wait, Moody's class? Imperius Curse?

Harry's heart was immediately poured with cold water, no, it was directly immersed in the black lake at the end of December. He shuddered and came out of this state. The gold powder in front of him was scattered and piled up on the ground into a cone-shaped handful, golden and beautiful.

But Harry didn't think it was a good thing now. In addition to everything he had just experienced, another direct evidence was that Professor Hep was holding Valen tightly, and the little guy stretched out a small hand from the gap in the professor's arm and reached out to the direction of the gold powder.

Harry leaned back in fear, and when he felt his back touching the back of the sofa, he felt a little safe.

"Three minutes."

Felix picked up a pocket watch and looked at it. He said, "It's faster than I expected. It's amazing."

Harry stammered, "I, I thought of Professor Moody..."

"I understand," Felix said, "He does look scary."

"No, no, professor," Harry said, "It's not because of Professor Moody's appearance that I..." He blinked and explained in a low voice, "He recited the Imperius Curse to us in class."

"That makes sense," Felix nodded slightly, "So you should have performed well in that class?"

Harry nodded hesitantly.

"Professor, what is that?" He watched Professor Hep wave his wand, and the scattered gold powder and the handful of powder on the ground disappeared at the same time.

"Some of the beautiful memories I collected." Felix smiled and said, "Many of them are from creatures in the Forbidden Forest. These little animals can easily get happiness. Maybe they don't fit your definition of beauty?"

"No, I think it's very good, pure happiness." Harry said reluctantly. He felt that some of his ideas were shaken. He had to remind himself that he was in front of an excellent memory master.

Felix said slowly: "This is the inspiration I got from the Dementors. Since the Dementors can absorb those happy memories, then I naturally thought, why can't I extract other memories and emotions?"

"If you suck out all the happiness, only negative and pessimistic feelings will remain. If you suck out all the arrogance and conceit, naturally only humility and respect will be left... You will find that emotions can easily go from one extreme to another. It is worth studying, but I have to say-it is not very useful to me, and it is easy to be criticized."

Harry felt that this evaluation was too light, and it should be described as evil or weird. He secretly glanced at Felix. Most of the time, Professor Hep was gentle and friendly enough, and his words made people feel like spring breeze. Not to mention that after the Christmas ball, many girls had a higher evaluation of him. But in terms of attitude towards some magic, the professor's standard was frighteningly low.

For example, if he hadn't had a nightmare that night, he might never have known that Professor Happ used the killing curse so skillfully...

"Will this help me learn the brain block technique?" Harry asked tentatively.

"Of course it will help. In the introductory stage of your learning, you will find that the strength of will is particularly important."

He handed Harry a book.

"Every page of it has been enchanted by me. In addition to what you have just seen, there are other ways to mobilize emotions and memory. You need to read it and ignore the influence of the magic attached to it. This book is dangerous, so I can't let you take it away. My arrangement for this special training is that during the Christmas vacation, you will come every two days, and after school starts, you will come once a week. When you can read from the first page to the last page without any effort, it means that you have completely mastered the subject. We will move on to the next stage."

Harry nodded to show that he understood. He took the book. It didn't look thick, with an ordinary cover and no title, but he didn't think that this book was more harmless than the "Monster Book of Monsters" carefully selected by Hagrid.

He turned the first page anxiously. At first glance, it looked ordinary. There was an unfamiliar spell on it, and the outer frame of the spell was a circle of purple arc-shaped patterns. But when he tried to identify it, the spell produced a strong attraction.

He looked at the pattern on it with an infatuated expression, as if the ultimate answer to all unknown puzzles was hidden in that small spell.

Felix let go of his hand, and Valen jumped out of his arms and ran to Harry's sofa. He stood aside and looked at Harry curiously, and glanced at the pattern on the book again. At the first glance, he found nothing. At the second glance, huh? It's pretty good, so I'll take another look...

Its sight became more and more focused. At this time, Felix came over and took it away. Valen blinked, and remembered what had just happened. It yelled twice with lingering fear.

"That book is not suitable for you. I will make you a 'Valen's Bizarre Adventure' some other day." Felix said jokingly. Valen patted his heart, avoided Harry and the book on his lap, ran to the workbench, took out gold coins from his pocket, and piled them on the table to build a castle.

Valen felt that it was too dangerous to build a castle with explosive cards, so it was better to use gold galleons - it was both beautiful and safe, and there was a sense of accomplishment after completion.

Felix and Sniff stopped from time to time to glance in Harry's direction. Harry's forehead was unconsciously soaked with sweat, which was a sign of rapid consumption of mental energy. Felix's brows were getting deeper and deeper.

Still unable to detect any abnormality...

Was it hidden too deep? The realm of the soul is indeed full of unknowns.

Time passed little by little, and the sweat on Harry's forehead evaporated, but he still didn't turn to the second page. He was completely lost. Felix looked at the time and it was almost time to turn off the lights. He stood up and wanted to interrupt Harry.

At this moment, he stopped. From the perspective of magic, a deep darkness stretched out its tentacles and appeared abruptly, hovering on Harry's forehead, as if it had always been there, but was covered by layers of fog.

Felix could not hide his shock. His and Dumbledore's guess had come true. Although he did not know the specific process, there was no doubt that Harry had a piece of Voldemort's soul hidden in him.

...

"Harry, this is a tranquilizer. Drink it and go back to have a good sleep." Felix said gently.

"Yes, professor." Harry yawned loudly. He was so sleepy now that he just wanted to go back to bed and have a good sleep.

When he returned to the common room, there were not many people inside. Hermione and Ron were waiting for him. Hermione asked in a chattering voice, "What does Professor Hep want to talk to you about?"

"Principal Dumbledore asked the professor to teach me the art of brain occlusion." Harry said tiredly.

"Occlumency?"

"What's that?"

Hermione and Ron said at the same time, but seeing that Harry was too sleepy to open his eyes, she quickly closed the book and said decisively: "Okay, we'll talk about it tomorrow. I completed a plan while you were away. Although some details are not clear yet, we roughly understand what the second project is going to do. Preparations must be put on the agenda."

"You decide, Hermione." Harry yawned again. Professor Happ's potion was very effective. He didn't feel a headache, but he was very sleepy. He went into the dormitory, changed into pajamas, and fell asleep.
