"This book is really interesting!"

In the orange Gryffindor common room, Clark snuggled up on the couch.

He was surrounded by a group of Gryffindor students playing card games, and it was clear that the Weasley twins' business was still booming.

Even Ron and Harry didn't have the heart to do their homework, and gathered around the table, watching the rich classmates play cards, and pointing out from time to time.

Thanks to the fact that he won Professor McGonagall's magic chess game last year, and that he had participated in the first test of magic cards, his advice was still very authoritative.

And in this noisy environment, only Clark is still reading the book seriously.

On the cover of the book, the face of a beautiful witch is printed, and the eyes of this witch are cold and empty, like a dark tunnel, bottomless, as if they can swallow people's eyes...... And the name of the book is "Close Your Brain".

"Hey, Clark." At this time, a voice interrupted him, "Stop reading, let's come over and play together." ”

George shouted his name, and Clark woke up from his trance.

"This book is really interesting!" He repeated it again.

At this time, Hermione had just crawled into the hole and happened to hear the words, "What's interesting?" ”

Clark looked at the cover of the book, and then looked up at the clock hanging on the wall, the time had pointed to six o'clock in the afternoon, and he had been sitting on the sofa for two hours, but the book had not even been opened.

"Close Your Brain, what kind of book is this?" Hermione walked over to Clark and looked down at the book in his hand.

However, this glance made her stand there stunned.

Clarke quickly flipped the book over, and Hermione came to her senses.

"What just happened?" He looked at Clark quizzically.

Clark turned the book back again, only this time, neither of them dared to look at the cover of the book again.

"This book 'Close Your Brain' is to teach people how to learn Occlumency, and it is clear that the picture on the cover of this book has magic, and anyone who sees it will be addicted to it, no matter how time passes, they will not be aware of it."

"It's horrible." Hearing Clark's explanation, Hermione exclaimed, "If no one reminded her, she wouldn't have starved to death like this." ”

Clark smiled and opened the book to the first page, "Of course, why do you think it's in the forbidden section?" ”

"Where did you get this, there is only one way to borrow a book from the forbidden area: get a teacher's autographed slip."

After speaking, without waiting for Clark to answer, she suddenly realized again: "Professor Lockhart, it must be Professor Lockhart!" It turns out that you left to find him to get this. ”

Clarke nodded, much to Hermione's amusement.

"What is this talking about?" She asked Clark, who was reading a book.

"Occlumency, a magic that protects your brain from outside intrusions, without the use of wands and spells, is a very secret, but very useful magic." Clark explained.

"As you can see, the picture on the cover of this book should have a Dementor Charm attached to it, so when we see it, we are immersed in the good memories of the past, and we forget the passage of time."

Hermione seemed to be transformed into a curious baby at the moment, "Regent, what is that?" ”

"It's also a spell, the counterpart of Occlumency, which extracts sensations and memories from another person's mind—"

"Can it read people's hearts?" Hermione asked immediately.

"Nope." Clark shook his head and looked away from the book, "There are some subtle differences. ”

He paused for a moment, as if he were organizing the language, so that he could speak the knowledge in an easy-to-understand manner.

"Only Muggles have the saying 'read people's hearts', and people's hearts are not a book, and it is impossible to read them casually. Ideas are not engraved in the brain, and it is impossible for people to get into them and read them.

The human heart is a complex, multi-layered thing. Just as cowardly people sometimes suddenly become very brave, some people who seem to be brave can suddenly become very cowardly when faced with danger.

We can never really see through people's hearts. ”

Of course, this does not include Psychic Warlocks.

Clark added to himself that compared to the Psychmancer's advanced psychic abilities, the Dementor's mind was as simple as a bicycle in front of a tank.

He laughed, "However, a person who can take the mind can study the minds of others and make correct interpretations in certain situations.

It's as if Headmaster Dumbledore can almost always see that others are lying to him, and only someone who is good at Occlumency can seal the feelings and memories that contradict the lie and lie in front of him without being detected. ”

"It sounds a bit like micro-expressions in psychology." Hermione, who had a dentist father, quickly came up with her own understanding based on her knowledge of the past.

Clark was stunned for a moment, admiring her.

"You're right, it's a bit similar, they can both judge whether the other's words are true or false based on one person's reaction? It's just that one relies on body movements, while the other relies on soul feedback. ”

"This book is really interesting!" Hermione looked curiously at the book "Close Your Brain", "Show me too." ”

Clark smiled and nodded, "Okay, but you have to wait until I'm done before you can read it." ”

Hermione snorted and turned away, which made Clark a little confused, not knowing which sentence annoyed him, so he could only lower his head and continue to study the book in his hand.

It took Clark two full days to finish reading "Close Your Brain".

Then, he spent another day watching "Make You Forget Unhappy".

It was only after reading it that he sighed that the little salary paid to Lockhart for these two books was really worth it.

Even for his Psychic Warlock profession, these two books are of great help.

Unlike Muggles' understanding of memory, in wizards' perceptions, people have souls.

Therefore, memory is no longer the lap of neurons and the secretion of hormones, whether it is brain occlusion or amnesia spell, it is through magic, acting on the human soul.

In order to better understand Occlumency, we must first understand the principles of "Mind Retribution" and "Forgetting Spell", because these two are like spears and shields for Occlumency, which is an opposing relationship.

It is because of their existence that there is cerebral occlusion.

As Clark told Hermione, the Deception is not a mind reader, it's not that subtle, it's not powerful.

According to Clark's opinion, it is more similar to the [Feeling Emotions] in the psychic ability, which can only perceive changes in people's emotions, and is not even comparable to the [Detection Thoughts] that can read the surface mind.

Not to mention the Level 5 [Mind Probe], which can fully detect all the secrets in the target's mind.

Of course, this does not mean that there is no merit in the Mind of the Deception.

First of all, this is one of the few remaining psychic detection spells in the wizarding world today, and apart from it, the only way to obtain the secret of the target may be to breathe the truth potion.

In contrast to Feeling Emotions and Detecting Thoughts, Soul Capture can also actively detect the thoughts in the target's mind.

As the so-called heart ape is like a horse, the thoughts and thoughts in people's hearts are often complex and changeable, and sometimes we don't even know what we are thinking.

Therefore, what the target thinks, [feeling emotions] and [detecting thoughts] can only receive something, which is a passive way, at most through language to guide the target to think in the direction they want to perceive.

However, this is not the case, it uses magic to stimulate the soul of the target, so as to judge what the other person thinks through the stress response of the other party.

This is very similar to the way Muggles study the function of brain blocks, which is to stimulate first, and then judge the corresponding role of this block based on feedback, which is a kind of exhaustive method.

Therefore, a masterful master of the Divine Receptive Mind often relies more on rich experience, so they will always subconsciously use this ability.

As for the Oblivion Charm, it also uses magic to stimulate the target's soul, but it is different from Soul Capture.

It does not need the reaction of the other party, but takes advantage of the opportunity of the disorder of the target's soul to use its own magic power to distort and forge a false memory, and take advantage of the chaos to insert into the target's soul, thus forming a memory overlay.

Yes, the Oblivion Charm is not actually to erase the memories in the soul, it can only overwrite the original memory.

Among them, novices with rough means can often only forge a blank memory, insert it into the soul of the other party, form a memory loss, and thus be discovered.

And a master like Lockhart, who is skillful in his means, can naturally weave a false memory that is logically self-consistent, reasonable, and echoes back and forth.

In this way, the original memory of the target is covered, to the extent that the truth is confusing, and the world is hidden.

Now that we know the principles of dementoring and forgetting spells, doing the opposite has become the core concept of Occlumency.

The first step of both spells is to stimulate the target's soul with magic, so the first step of Occlumency's work is to resist this stimulus.

No, perhaps the word "resistance" is a bit inaccurate, and the more figurative term would be "inclusive".

After all, the human brain and soul are extremely delicate things, and if they resist and conflict with external stimuli, who knows what kind of damage will be done to the soul?

Therefore, the first sentence on the title page of "Shut Your Brain" is "Empty your brain", which is quite a bit of Taoism's pure and natural, avoiding reality and emptiness.

Eliminate distracting thoughts, throw away all feelings, and the heart is like a quiet lake, without starting from the waves.

The brain that he emptied first made his soul blank, and the enemy had no way to find what they wanted, and the so-called covering memory of the forgetting spell was naturally impossible to talk about.

Of course, this is only the most rudimentary use of the Brain Defense Technique, which simply means emptying one's house so that the thief has nothing to gain.

A more advanced use would be, like Lockhart and Snape, who could even construct a false memory on their own, deceiving the enemy they were probing, and leaving them unaware.

Seeing this, Clarke, combined with his [Psychic Warlock] professional perception, has gained more.

It's no wonder that the Brain Defense Technique can do without the use of magic wands and spells, because it is not magic per se, and according to his understanding, it should be a form of spiritual cultivation similar to Buddhist meditation.

No, it is even possible that some of the Buddhist practices they have acquired from their colony of India are different from the complete set of Buddhist practices and detailed rituals.

The whole book "Close Your Brain" describes only a few babbling and specious perceptions, which make wizards who want to learn this spell in detail only understand it by their own roots and talents.

It's no wonder that the book makes it clear that Occlumency is a very gifted spell that people with talent can learn it quickly, while those who don't have it can't learn it even if they practice it for a lifetime.

Just like Harry in the original book, as an impulsive Gryffindor, recklessness was almost engraved into his bones, and it was okay for him to be a fighting barbarian monk, and it was almost impossible for him to sit down and recite the scriptures.

Perhaps the only good thing about this book is the enchanted picture on the cover.

After all, we practice Occlumency in order to hide the secrets in our brains, and it is naturally impossible to ask a powerful wizard to perform a regent on us to verify this.

And looking at the teaching content in this book, which is full of emotional babbling and has no hierarchical logic, no matter how hard you try, it is impossible to know how far you have trained.

It is only through the cover of the book, based on the time I have been obsessed with magic pictures, that I can roughly judge how effective my Occlumency training is.

After a preliminary understanding of this, Clark began to try to do it.

In contrast to the Dementor Mind and Oblivion Charms, which also require the use of magic, the Occlumency Technique, which uses purely mental power, can be used even by Clarke.

He didn't pick a place, he sat cross-legged on the soft bed, learned the meditation he had seen on TV before, relaxed all over, closed his eyes directly, as if he had fallen into a deep sleep.

The brain is empty, and there is no thought......

Maybe it's because he's a Psychic Sorcerer, or maybe he's really talented.

In short, when Clark began to train in the Brain Defense Technique, his breathing became lighter and his presence became weaker.

In the end, his breathing was even imperceptible, his chest did not rise and fall, and the whole person seemed to be a lifeless stone statue.

An unprecedented tranquility began to fill Clark's mind and body.

This kind of tranquility is not a physical tranquility in the ordinary sense, but a spiritual tranquility.

It was a very strange state, and in this state, Clark only felt as if he had discovered a new world.
