Hogwarts: I am the White Demon King

Occlumency!

This is a very difficult and obscure advanced magic that can seal one's mind and prevent foreign intrusion into the brain.

Why learn it now? Is there someone I need to guard against?

Malfoy was a little puzzled, unable to understand Sebastian's intention for a while.

Forget it, why think so much.

The professor is willing to personally teach this advanced magic, what's there for me to be picky about.

Just learn it.

"Harry," Sebastian looked at Harry, "You've previewed the relevant knowledge before, what have you gained?"

"Um..." Harry scratched his head embarrassedly, "The things in the book are a bit profound, and I didn't quite understand them."

"According to my understanding, after we learn Occlumency, it's like installing a door in our brain, so if others want to see my memory, they must open this door."

"I don't know if my understanding is correct."

"Haha," Sebastian laughed heartily twice, "Your understanding is good, but it's not enough."

"Or rather, that's just the first small goal achieved in the process of learning Occlumency."

Many people misunderstand Occlumency. They think that the human brain is like an open room, and anyone who comes in can see whatever they want.

After learning Occlumency, it's like adding a sturdy door to the room, and others need to use all means to open it.

If that's the case, then Snape would not have been able to go undercover in front of Voldemort at all.

After all, having a door standing there is not a blatant way of telling Voldemort that this person has a problem.

Of course, if you have to understand the brain as a room, then the real advanced usage of Occlumency is to secretly build a memory palace behind this room.

Then, put the memories you want others to see as decorations in the first room, without even installing a door, just let people visit directly.

If you are a memory master, you can even directly fabricate some fake memories and put them in that room to confuse others.

In the original book, Voldemort fabricated a memory of capturing Sirius and torturing him, making Harry believe it was true and directly falling into a trap.

Under Sebastian's detailed explanation, Harry and Malfoy gradually understood the wonderful use of Occlumency.

They desperately took notes, for fear of missing a word.

After Sebastian finished explaining the function of Occlumency, Malfoy raised his head and asked eagerly: "Professor Swann, how do we construct a memory palace in our minds?"

"That's too far away from you," Sebastian smiled, "Take it step by step, first establish a door in your mind to block others' prying."

"It's not that simple to do this. You need to learn to clear your mind, not to recall or think."

"In other words, you need to learn to close your heart, control your emotions, and maintain a calm and composed state."

"Remember, if you can't learn to control your emotions, then you will never take the first step in learning Occlumency."

In fact, this sentence is also very easy to understand. After all, even Muggles can use observation to guess other people's thoughts.

If you can't control your emotions, the other party can see you through and through just by looking at your expression.

For masters of Occlumency, everyone has unique emotional management skills.

Like Snape, he always has a cold expression, as if he doesn't show any emotions other than indifference.

Like Dumbledore, he always looks quiet and easy-going in people's eyes, and you never see him angry.

"I have two methods for learning Occlumency here. One is the traditional learning method. Although it takes effect relatively slowly, it is better in stability."

"There is also a crash course learning method, which has certain risks, but it can allow you to learn it within half a year to a year, and even if the efficiency is higher, it is not impossible to shorten the time to two or three months."

"Which method do you two want to choose?"

Needless to say, there is no hesitation at all.

You must choose the fastest one!

Harry chose the crash course method without hesitation.

Malfoy originally wanted to ask what the risks of the crash course method were, but seeing Harry's decisive appearance, he instantly swallowed the question he wanted to ask.

Crash course is crash course.

If I keep asking, Potter will think that I am less courageous than him.

"Professor Swann, I also choose the crash course method."

"Good!" Sebastian nodded approvingly, "In that case, then you two will compete to see who can graduate from me first."

"I can fulfill a small request for the winner."

Hearing this, Harry and Malfoy instantly became full of fighting spirit. They looked at each other and could see the competitive spirit in each other's eyes.

Humph!

I will definitely be the winner!

Seeing the two people's unconvinced appearance, Sebastian said.

"Practical combat is always the fastest way to learn spells. Normally, I would use spells to pry into your minds, so that you can quickly learn to control your emotions and then close your hearts."

Ah?

So this is the crash course method.

In this way, wouldn't the professor be able to see all his privacy.

Harry and Malfoy's faces instantly collapsed.

Professor, you are so strong, what can we use to defend our minds!

Can we still raise our hands and say that we regret it?

"However! My strength is a bit too high for the two of you. In order to help you quickly build self-confidence, I am going to find you each an opponent of comparable strength."

Sebastian grinned: "I will first teach you Legilimency, and then you two will be each other's opponents to see who can protect their memories first."

Good家伙!

Let Malfoy (Potter) see his own memory......

It's better to let the professor come in person, at least it's not so embarrassing.

Harry and Malfoy looked at each other and could see the strong disgust in each other's eyes.

Sebastian ignored the two people's thoughts and directly began the Legilimency teaching.

Attack spells are always easier to learn than defense spells. With Harry and Malfoy's level, they quickly mastered Legilimency initially.

Everything is ready, all that's missing is the east wind. Sebastian waved his hand and directly let the two begin spell practice.

Since things have come to this, both of them are going all out.

Anyway, you can see my memory, and I can see yours, everyone is embarrassed together, no one suffers.

However, the problem came again. Harry and Malfoy both wanted to be the attacker first.

Seeing that the dispute could not be settled, the two had to discuss using rock-paper-scissors to determine the winner. The winner attacks and the loser defends, and then they take turns.

"Rock, paper, scissors!"

Harry stared at his fingers hatefully. The scissors he made were particularly weak at this moment.

He raised his head unwillingly and happened to meet Malfoy's smug face. He shook his fist and said triumphantly: "Potter, you have to accept your loss!"

"Okay," Harry clenched his fist weakly, "You won, come and attack me."
