Chapter 20: The Disillusionment Charm

After Halloween, November arrived, and the weather at Hogwarts suddenly turned bitterly cold. For the students of Hogwarts, the most important thing at the moment was the start of the Quidditch season. But for Eisen, the snowy season was more captivating.

Every morning, the ground was covered with a thick layer of frost, and the surrounding fields were blanketed in a thick blanket of snow. Since being recommended by Professor McGonagall as the Gryffindor Seeker, Harry had been training for several weeks. Saturday was the day of Harry's first official match. The opposing teams were Gryffindor and Slytherin.

If Gryffindor won, they would move up to second place in the House Cup standings. But as for Eisen, he didn't care about any of that. Because he was learning the Disillusionment Charm from Professor Flitwick.

"Oh, Professor Eisen, the Disillusionment Charm is a very difficult spell, but I believe you must know the technique for casting it, don't you!" After Eisen made his intentions clear, Professor Flitwick specially took him outside the school's grounds. There was no choice, as the entire Hogwarts was protected by an anti-Disapparition jinx.

"Yes, Apparition follows the three D's: Destination, Determination, and Deliberation. But even so, it's very dangerous, and you need someone by your side to learn it!" Eisen had already begun researching the Disillusionment Charm.

Afterwards, Eisen began practicing the Disillusionment Charm in front of Professor Flitwick. Since Eisen understood the Disillusionment Charm deeply enough and could grasp the technique of casting it, it didn't take long for Eisen to master Apparition completely.

Indeed, initially due to unfamiliarity, Eisen's attempts at Apparition resulted in his fingers becoming detached. Fortunately, Professor Flitwick was nearby and could help him promptly.

But after a few practice sessions, Eisen could skillfully master Apparition.

"Excellent, Professor Eisen, you've mastered this spell perfectly." Seeing Eisen master this highly difficult spell in just half an hour, Professor Flitwick couldn't help but praise him.

"No, I feel like I still have a long way to go, but I must thank you, Professor Flitwick!" Eisen shook his head. In fact, although Eisen joked with the young wizards in class about using Apparition to go to the moon, now that he had learned it, he really did want to make a moon landing his goal.

Therefore, Eisen felt he still had a long way to go. However, he still expressed his gratitude to Professor Flitwick.

What bothered Eisen, though, was that even though he had learned Apparition, he couldn't teleport within Hogwarts. Thinking about how house-elves had the innate ability to bypass Hogwarts' magical restrictions, he was extremely envious.

Of course, regarding Apparition, Eisen suddenly had a doubt: if a wizard first used the Disillusionment Charm, then Apparated, wouldn't that make them even more concealed? Thinking of this question, he asked it directly.

"Hmm, that's a good question, but during Apparition, the spatial compression wave might cause the Disillusionment Charm to fail." The professor was surprised by Eisen's idea but gave his guess.

"However, if you deeply study these two spells and understand their essence, combining them or even inventing a new spell wouldn't be a problem." The professor then mentioned another possibility.

In fact, this possibility did exist. Just like in the original story, although Dumbledore had never done it, no one could deny that he was capable of it.

However, thinking about his own cheat ability, Eisen felt there was no need to dwell on it too much. For now, Eisen could say he had completed his initial small goals.

The Disarming Charm, Transfiguration, and Apparition – Eisen had already mastered these three. Not to mention the Disarming Charm for attack and Apparition for escape and travel, his in-depth study of Transfiguration alone was enough for offensive and defensive battles against enemies.

Therefore, with these abilities, Eisen only needed to continue studying and practicing. Some might say the Disarming Charm's offensive power was insufficient, and ordinary injuries could easily be healed by healing spells. They might suggest learning some extremely powerful Dark Magic, like the Killing Curse.

But in reality, for Eisen, this was not a problem. As time passed, Eisen's magic power would grow stronger, and his overall physical condition would slowly improve.

As a result, his Disarming Charm could essentially become an all-powerful offensive spell, just like Harry's in the original story. While disarming the opponent's wand, Eisen could also use Transfiguration to bind the enemy, then use the Blasting Curse or simply Transfigure a knife to kill them.

Eisen felt that a bound, immobilized wizard would definitely be unable to heal themselves. In that case, there was no need to specifically learn Dark Magic.

As for why Eisen resisted learning Dark Magic, it was because the Dark Arts in this world were truly sinister. Originally, Eisen's understanding of Dark Magic was very superficial, but he generally knew that Dark Magic was evil and required malice and extreme negative emotions as fuel for its casting.

But recently, after a slightly deeper understanding from the library, Eisen discovered that delving into the study of Dark Magic would inevitably lead to the corruption of one's soul.

Logically, if extreme negative emotions were frequently brewing within, then soul corruption was only natural. But soul corruption was clearly something Eisen did not want to see. So, he was very resistant to learning Dark Magic.

As for why Professor Snape was obsessed with studying Dark Magic but had not been corrupted by it and turned into an evil person, Eisen thought it was related to his heart being filled with love for Lily Evans.

In other words, positive emotions could counteract the soul corruption caused by Dark Magic.

As for Dark Magic being powerful and having great destructive force, Eisen thought it wasn't important. Because wizards were still human, and they would die if killed. So, in Eisen's view, ordinary spells could also kill, so there was no need to use Dark Magic to kill.

Besides, Dark Magic was considered dark not because it could cause death, but because it was sufficiently evil. Just like the Killing Curse, it was so evil that it had no counter-curse, which was why it was classified as Dark Magic.

Although Eisen considered himself filled with sunshine and happiness, he still didn't want to experience using positive emotions to resist soul corruption from Dark Magic. After all, Eisen had a cheat ability, so becoming powerful was still very easy for him.

After bidding farewell to Professor Flitwick, Eisen returned to the staff quarters.

In the time that followed, in addition to using various spells in daily life, Eisen would also find time to practice the combined use of Transfiguration, the Disarming Charm, and Apparition outside the school grounds. Of course, in between practice sessions, he would also devote some effort to researching Occlumency and the Patronus Charm.

There was no choice – although he wasn't worried about Dumbledore using Legilimency on him, he couldn't let his guard down against Voldemort. As for the Patronus Charm, it was mainly to defend against Dementors.

Dementors in this world were simply a bug – no spell, not even the Unforgivable Curses, could affect them in any way. One could say they were immune to all spells except the Patronus Charm. So, Eisen had to find time to learn these two spells.

Apart from that, most of his time was now spent on researching magical artifacts and alchemy. As Eisen immersed himself in his own world, the Quidditch match was about to begin.

...

With Harry busy preparing for the Quidditch match, after Halloween, Hermione not only helped him complete his assignments but also lent him a copy of Quidditch Through the Ages.

Unfortunately, perhaps due to their behavior at the Halloween feast, Professor Snape grew even more resentful, so he confiscated Harry's copy of Quidditch Through the Ages on some pretext.

On Friday evening, Harry planned to go see Professor Snape and get his book back. But he unexpectedly saw Professor Snape's leg bleeding profusely.

For this, Harry not only didn't get his book back, but was also berated by Snape. Afraid of losing House points, Harry quickly ran back to the Gryffindor common room. 

At this time, Harry remembered the three-headed dog standing guard over some secret on the forbidden third floor corridor, the troll that appeared on Halloween, and Snape sneaking toward the third floor. 

Recalling Snape's injured leg, Harry felt he had grasped the truth of the matter. Harry told Ron and Hermione all of his suspicions.

"No, I know he's not nice, but he wouldn't try to steal whatever Dumbledore is guarding," Hermione voiced her opinion, clearly not agreeing with Harry's view.

But Ron thought Hermione was being too optimistic, thinking all the professors were good people. He agreed with Harry's perspective. They just didn't know what exactly Snape was trying to steal.
