Chapter 139 Dark Magic

Jon directly copied the knowledge related to Invisible Sword: Sectumsempra on a notebook and placed it on Dumbledore's desk and said straightforwardly.

"Professor, I got something from that castle."

Dumbledore wiped the frame of half-moon glass, and then put it back on, his eyes fixed on the notebook that Jon put on the table, and then he said with a slight surprise.

"It is indeed a wonderful work." He looked back up at Jon, "Where did you get the knowledge on this notebook?"

Regarding the ring, Dumbledore was obviously unaware of it.

Slughorn also specifically instructed Jon when he gave him the ring, asking him not to talk about the existence of this ring with anyone, so Jon has also kept this promise.

As for why Dumbledore did not ask him about this matter, it should be Slughorn who had helped Jon to patch up before leaving the wagon, after all, on the night the fat walrus stole the philosopher's stone, Jon used the strange levitation charm once in front of Dumbledore, but Dumbledore did not ask him about this matter.

"It's something to do with a thing that Professor Slughorn has taught me before." Jon carefully worded, "when I was in the castle, many books in the restricted section of the castle library suddenly lost their magic one night, then I got to take the magic that was drawn out of these books, after which I only had to slowly charge magic into it now, and it would allow me to see the restricted books originally collected in the restricted section little by little."

Dumbledore nodded thoughtfully as he took the Invisible Sword: Sectumsempra manual into his hand.

"So, this is what you obtained after collecting enough magic?"

"Yes, Professor."

"Do you want to, uh, learn it?"

Jon didn't even need to initiate the conversation, Dumbledore had already seen the purpose of his visit this time.

This is indeed the main reason why Jon took the initiative to inform Dumbledore about the existence of the restricted rook, he wanted to learn some useful and powerful dark magic including the Invisible Sword spell, which he certainly could not hide from this old man.

There is no place to learn these kinds of magic inside the wagon, and as long as he uses it in the future, it will definitely lead to a series of problems.

So instead of waiting until after the doubt and suspicion placed on him, it is better to say things clearly at the very beginning, and Jon does not think there is anything wrong with saying that he wants to learn dark magic.

The men of Hogwarts and the Order of the Phoenix led by Dumbledore have already been crushed in many aspects, such as numbers and strength when fighting with Death Eaters and Aurors, yet can they still only use the stunning spell, full body-bind curse and disarming charm? Which has no lethal effect in the fight against their enemies.

After watching their friends and relatives die one by one under the enemy's magic spell, no one can suppress their inner hatred, just like Lily now.

Dumbledore can pledge that he would refrain from using dark magic, but he has no ability and no reason to restrain others.

Perhaps these rebellious wizards still have enough insistence not to misuse the three unforgivable curses, but for dark magic like the Blasting Curse, the Fiendfyre, they will never restrain themselves.

Given such circumstances, Dumbledore also has no reason to prevent Jon from learning, at most, he will add some restrictions for learning.

"I must first congratulate you on acquiring a great fortune, Jon." Dumbledore said seriously, "The collection of books in Hogwarts castle is the richest in the entire European wizarding community, and those that are classified as restricted books are invariably extremely dangerous and contain powerful magic as well as knowledge. If you can master all those books, I can guarantee that you can become more powerful than anyone else, but."

His azure eyes gazed at Jon.

"But the more powerful it is, the easier it is to get lost, and while the knowledge is tempting, not everyone can afford it. These words may not be persuasive, but I have to tell you."

"I will not restrict you from learning the magic in those restricted books, but you have to learn to grasp your own level better, don't lose your eyes for those false, seemingly powerful power."

For such a response from Dumbledore, Jon actually felt a little surprised, he obviously remained relatively at ease towards him, using a verbal reminder rather than actual restraint.

This probably stemmed from Jon's performance during the second-year infiltration, causing Dumbledore not to worry too much about the tilting of his mentality.

"I'll keep an eye out Professor." He promised with a nod, then asked hesitantly, "Is it true that dark magic would affect wizards?"

"As long as it is magic it will affect wizards." Dumbledore said calmly, "We will have to think all kinds of emotions and intent in our mind when we cast a spell, these emotions are the source of our power of magic, and most of the time, when casting transfiguration and some ordinary spells such as levitation charm, cleaning spell, full body-bind curse and so on, wizards have to believe that they could achieve that effect."

"The reason, why dark magic is called dark magic is that when using this kind of magic, the wizard's emotions inevitably become dark, with the desire to attack and hurt others. Once the use of dark magic becomes a habit, that weak-willed will unconsciously change by the emotions of the spell casted, become irritable and easy to anger, believing that they can control the lives of others at will, the three unforgivable curses are one of the most potent curses that can affect our minds, that's why, in the era of peace, it is illegal to use the unforgivable curse on people."

"Now many people in the Order of the Phoenix use dark magic as their main offensive means, but I have specifically restricted the right to use dark magic for some people," Dumbledore said it quite frankly.

"Most of them are more impulsive and can easily be affected by dark magic. Your performance throughout this school year has shown your sanity and calmness, Jon, I believe you can completely control yourself, Horace also made a promise to me on this matter before he left, he said you are different from everyone else, even if one day your body turns hostile, you will never betray yourself. I trust him, and I trust you, so I won't stop you."

What Jon needed was this statement of assurance from Dumbledore.

What he lacked most at present is the offensive means, and dark magic is known for its extremely destructive power, and he is confident enough that he can control his own 'will' and not be easily swayed by his emotions.

Just when this conversation was about to come to an end, Jon suddenly noticed the name on the envelope of the letter that Dumbledore had placed on his desk, and Dumbledore noticed his gaze and did not put the letter away anymore.

"Adele Roland, you've heard the name before in France; I recently got in touch with her and learned something about the French magical community."
