In the Harry Potter Without Harry Potter

Chapter 134: Sectumsempra

Of the books included in the Restricted Section, except for the history books that were written with consciousness and unbiased views and facts that Voldemort wanted to seal, it is likely for other books to have some kind of forbidden knowledge on the subject of magic.

It is also possible for such a book to need magic as a carrier of knowledge, or it may be simply the bad taste of the author and creator of that book (Grimoire).

And this gem that Jon got from the library, has absorbed the majority of the magic in the restricted books.

And the knowledge that relies on the magical power to be held could not have disappeared for no reason, Jon had a feeling that it is still present in this gem.

He looked at the pale blue gem, thought for a moment, and then used it to recite the incantation of the general counter-spell, applying the general counter-spell to his own body.

Now there is no more magic on the gem for him to use, this general counter-spell's level is based on Jon's own magic power.

If the strength of the spell that hit his body did not exceed his own magic threshold, the spell would be cancelled, and the magic attached to it would be absorbed and stored by the gem for him to use for casting spells using the ring.

But if the spell exceeds Jon's magic threshold, then the general counter-spell he cast on himself would have no protective effect.

Now that the gem is empty without a trace of magic left in it, Jon wants to try to get it to absorb some magic again and see if he can see some kind of difference.

After using the counter-spell on himself, he held his wand and turned the tip to aim at himself.

Then he recited a minor hex that would do little to no physical damage.

The spell struck Jon without any surprise, but it did not produce a single reaction on him, which did not surprise him, because even if he cast the spell with his wand, he could still use the general counter-spell to cancel his own spell, and there was no reason for the ring to not work when he cast the spell.

But even though the effect of the spell was cancelled, he did not notice any signs of magic growth in the second gemstone embedded in the ring.

So, it's not possible to absorb and store the magic he cast on himself into the ring.

Jon stroked his chin and looked at the ring in his hand and fell into a moment of contemplation.

In fact, when he thought about it, this is normal.

The wizard's own magic power is constant, the level of magic you have, you will be able to cast magic of that level.

The ring can help Jon to enhance the power of a spell he casts, by utilizing the absorbed magic of others and Jon's own magic together with a superimposed effect, to gain a boost.

If the magic is derived from Jon himself, then it should not have any reaction to something that has the same root.

After thinking about this, Jon became much clearer.

He got up from his chair and was about to go out to the common room when Neville pushed the door to come back at this time.

"The little girl named Gabrielle is not as afraid as she was when she first arrived, she has gotten acquainted with Lavender and Hermione, and even asks if she can come to the boys' dormitory to play with you."

Neville said as he walked in from outside.

"I told her that Professor McGonagall has allocated her a room among the first-year girls' dormitory, where she can spend her time resting if she wants to, without disturbing others at night, and she doesn't have to attend classes at school, so she can play with you whenever she wants, but not in the boys' dormitory ... "

Neville said as he closed the door behind him, when he turned back, he suddenly found Jon looking at him with a glowing gaze that startled him.

"Why are you looking at me like that? Should I ask Gabrielle to come to find you in our dorm room?"

He thought Jon was upset that he had taken matters into his own hands without asking, but Jon shook his head decisively.

"No, you're right to discourage it; she's only seven, but she needs to be taught the difference between boys and girls at this point in her life."

"Then why are you looking at me with that look?"

"Use a hex on me, Neville." Jon said seriously.

Neville froze for a moment, then asked with a serious look on his face.

"What kind of curse are you under? Do you need my help to break it for you?"

"No, I want your help to cast a hex on me."

A brief silence descended on the dormitory room, and it was only four or five seconds later that Neville stared at Jon with a peculiar gaze.

"You're crazy!"

"I'm perfectly sane." Jon didn't explain too much to him, just continued, "It's just a little experiment, you're certainly not going to hurt me, and I'm not stupid enough to hurt myself. Use one of your best spells on me, hexes and jinxes are fine too."

Neville has a high trust in Jon, and with the previous experience of last year's levitation charm, he also knows that Jon will always work on some unusual and strange spells.

So, hearing Jon's urging, he hesitantly took out his wand and finally asked.

"Is full body-bind curse okay? I haven't come into contact with any hexes, but I did familiarize myself with practising full body-bind curse as you studied full body-bind curse last year."

"No problem." Jon naturally had no objection.

Neville did not hesitate any longer, he raised his wand at Jon, and Jon did not perform any protective measures.

"Petrificus Totalus."

Red beams of light shot out from the tip of Neville's wand, hitting Jon's body straight on.

But the spell was like a stone sinking into the sea, not causing half a splash, not only the full body-bind curse effect did not reflect the slightest, but even the impact force that should have been carried by the spell also disappeared.

Neville blinked his eyes hard, he guessed in advance that Jon might be working on some magic research again, but he never thought that he would take on the full body-bind curse on his own body without even swaying a bit!

Jon and Neville are roommates, so he naturally is aware of Neville's magic volume, a little stronger than Ron, Justin and Lavender and the rest of them, but a little less than him.

Therefore, the general counter-spell on his body can be effective against it is something that Jon expected, and the crux of the issue is the gemstone in the ring.

He did not immediately explain to Neville why his full body-bind curse had no effect at all, Jon took the ring back to his hand and carefully observed the colour of the second gemstone, which he faintly felt to be a little darker than the previous shade.

After that he quietly perceived it, and indeed detected a trace of wandering magic in the gemstone.

And this magic power obviously belongs to Neville!

But the magic is so weak that if Jon hadn't been more careful, he wouldn't even necessarily have been able to perceive it.

Compared to before when he first got this gem when it was still crimson, it was as big as the difference between a drop of water and a river.

But Jon's focus was also not on the magic absorbed by the gem, he looked at the gem with his mind and always felt that the magic obtained from Neville's full body-bind curse was connected with the title of a book on the gem on its own.

The content of that book could not be seen, nor did he know how thick it is as if Neville's magic could at best make it show the book cover.

It took a lot of effort for Jon to finally read the title of the book.

The Invisible Sword: Sectumsempra

And under the title of the book, he also saw a familiar author name - Severus Snape!
