Hogwarts: I am the White Demon King

Apparition, a unique magical way of travel, allows wizards to easily reach the places they want to go. This extremely practical advanced spell is usually taught starting in the sixth grade.

The reason is actually very simple: in addition to a higher requirement for magic intensity, Apparition also has strict standards for the stability of a young wizard's magic.

During puberty, young wizards' magic is in a stage of rapid growth, changing almost daily. This instability makes it difficult for them to master the precise control required for Apparition.

Only after young wizards reach adulthood at 17, when their magic has relatively stabilized, is it the best time to learn Apparition.

In addition, learning Apparition places considerable demands on a young wizard's psychological resilience. If they cannot remain calm and focused, the Apparition process can easily lead to 'Splinching,' where a part of the body fails to move to the target location with the spell.

Worse still, the experience of Apparition itself is quite challenging. The feeling of being squeezed to the limit often causes beginners intense discomfort, even leading to a fear of the skill.

Splinching, coupled with the nauseating experience of being squeezed flat, can easily make young wizards reject Apparition, even causing psychological trauma.

Moreover, the existence of Floo Powder ensures that wizards can travel conveniently, so these young wizards are even less interested in Apparition.

As a result, every year a certain number of graduates fail the Ministry of Magic's Apparition test and do not receive the corresponding certification.

Sebastian had once tried to add Apparition to the students' graduation exam spells, but ultimately gave up, retaining only the Shield Charm, Petrification Curse, Stupefy, Disarming Charm, and other basic spells.

However, for the few young ones in front of him, Apparition was an essential skill. They would eventually go to the battlefield, and more mobility meant a greater chance of survival.

Fortunately, these young ones were all top students at Hogwarts, so even though they were still in puberty, they had reached the required level of magic control to learn Apparition.

Sebastian instantly switched to teaching mode: "We've been studying for over ten days now, let's first review the key points of Apparition. Neville, can you explain the three D's of Apparition?"

Hearing Sebastian call his name, Neville was momentarily stunned, quickly organizing his scattered thoughts, forcing himself to calm down and stop thinking about being a prefect.

After a moment of thought, he accurately replied: "The three D's are Destination, Determination, and Deliberation."

"Very good." Sebastian nodded slightly, then shifted his gaze to Ron beside Neville.

Seeing this, Ron straightened his expression and immediately seamlessly continued.

"First, we need to focus our attention on the place we want to go, which is the Destination. It could be a place within our sight, or a place we've been to before. In any case, we must know it well enough, preferably familiar enough to recall all the details of the target with our eyes closed."

Sebastian looked at Ginny again, and the little girl immediately continued: "Next is Determination. When Apparating, you must have an extremely strong desire and, while mobilizing your magic, firmly believe that you can succeed."

After Ginny finished speaking, Hermione immediately added: "Finally, there's Deliberation. During the spellcasting process, you must not be nervous or afraid. These two emotions will affect the concentration on the target and the firmness of the Determination. You must always maintain a calm state of mind, otherwise it is easy to fail the movement or even Splinch."

"In addition, there is a distance limit to Apparition. As the distance increases, the difficulty becomes greater and greater, so you must act according to your ability to avoid Splinching, serious injury, or even death."

"There's one last point," Hermione added in detail, "Professor, you said that for beginners, when Apparating, you must remain calm, rotate in place, and allow yourself to enter a state of emptiness. Or, imagine your body becoming nothing."

After speaking, Hermione looked at Sebastian, expecting his praise.

"Great!" Sebastian glanced approvingly at everyone, "You are all great, your theoretical knowledge is solid."

"But it is easier said than done. To this day, none of you can fully meet the above standards. Same as usual, let's start with accelerated teaching."

Hearing this, Ron couldn't help but grit his teeth.

There was no way around it. Sebastian's accelerated teaching was actually high-intensity desensitization therapy, using the convenience of Side-Along Apparition to quickly get the young ones used to the discomfort that Apparition brought to the body. After the body adapted to this feeling, he would let the young ones practice on their own.

However, Sebastian's requirements were very high. He would take the young ones to Apparate continuously, raising their threshold of tolerance.

In this way, the young ones were both pained and happy. They were happy that their learning progress was gratifying. In the short ten days since arriving at Swan Manor, they were able to successfully cast Apparition, but the success rate and accuracy still needed to be improved.

The pain was that the process of raising the tolerance threshold was really uncomfortable.

Sebastian certainly knew the pain of the young ones, so he prepared to give everyone a little bit of motivation to work hard.

"Apparition can be used in combat when practiced to an extremely skilled level, and then bring a huge boost to combat power."

"Many well-known wizards have mastered this skill, such as the Headmaster Dumbledore you are familiar with. Here, I can give you a demonstration."

A demonstration?!

Such a good thing?

The young ones' eyes lit up, and they all widened their eyes. Ginny hesitated for a moment and opened her mouth to ask.

"Professor, shouldn't we wait for Harry? Wouldn't it be a pity if he couldn't see the demonstration?"

"No need," Sebastian waved his hand, "He has seen it many times."

Saying that, he shouted in the direction of the villa: "Garfield!"

Soon, a dark little cat came running over, which was the Kneazle adopted from Newt Scamander's Romanian Dragon Sanctuary.

After a year of careful cultivation, the Kneazle had now passed its juvenile stage and possessed considerable combat power, making it suitable to play the role of a teaching aid.

Sebastian approached Garfield's ear and whispered a few words, promising that there would be dragon meat for dinner as a reward. Garfield narrowed his eyes, meowed, and gladly accepted the task of teaching aid.

Under the astonished gaze of Ron and the other three, Garfield suddenly began to change. His body swelled instantly, becoming half a person tall, and then, with Sebastian's help, split into four.

Their fur shone with a glossy luster, like fine velvet, and looked particularly soft and smooth in the sunlight.

Slightly moving their bodies, they surrounded Sebastian from four different directions, then crouched down, like four black panthers, posing in a stance of accumulating power before attacking.

"Young ones, don't blink, you will witness the most profound skills of Apparition."
