In This Hogwarts Without a Savior

Books that can be classified as banned, except for some historical books about consciousness and thought that Voldemort wanted to deliberately seal, the books themselves may have problems of one kind or another.

It may be that the knowledge recorded in the book requires this magical carrier, or it may just be the creator's bad taste.

And the gem that Jon got from the library absorbed the magic power of most of the forbidden books.

And the knowledge that relies on magic power cannot disappear for no reason. Jon always feels that it is still in this gem.

He looked at the light blue gem, and after thinking for a moment, he used it to recite the incantation to break the spell, and attached a universal breaking spell to his body.

Now there is no extra magic power on the gem for him to use, so the threshold for breaking the spell is Jon's own magic power.

If the strength of the spell that hits his body does not exceed his own magic threshold, the magic will be erased, and the magic attached to it will be absorbed and stored by the gem for use when he uses the ring to cast spells.

But if the spell exceeds Jon's magic threshold, then he will have no protective effect against the universal breaking spell he releases.

Now that the gem is empty, and there is no trace of magic left in it, Jon wants to try to let it absorb some magic again to see if some changes can occur.

After he used the breaking spell on himself, he took hold of the wand and turned the tip of the wand to aim at himself.

Then he recited a small curse that did little harm to the body.

The spell hit Jon without any surprise, but there was no reaction on his body. This was not beyond his expectation, because even if he cast a spell with a wand, he could use the breaking spell to break his own spell. It made no sense. It won't work if you change the ring.

But even though the effect of the spell was erased, he didn't find any sign of magic growth in the second gem set on the ring.

If you cast a spell on yourself, there is no way for the magic power to be retained in the ring.

Jon touched his chin and looked at the ring in his hand, lost in thought for a while.

In fact, if you think about it carefully, this is normal.

The wizard's own magic power is constant, and the magic power can be cast according to the level of magic power.

The ring can help Jon enhance his spellcasting power by absorbing other people's magic power and creating a superimposed effect with Jon's own magic power to gain improvement.

If the magic power comes from Jon himself, then logically there shouldn't be any reaction between things that have the same origin.

After figuring this out, Jon suddenly became enlightened.

He stood up from the chair and was about to go out to the common room when Neville opened the door and came back.

"The little girl named Gabrielle is no longer as shy as when she first came here. She has become familiar with Lavender and Hermione, but sometimes she still talks about whether 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 arranged her into a first-year girls' dormitory. She can rest there as long as she doesn't disturb others, and she doesn't have to attend classes at school. If she wants to play with you, she can always Yes, but not in the boys’ dormitory…”

Just as Neville was closing the door, he turned around and suddenly found Jon looking at him with a bright look, which startled him.

"Why do you think so of me? Should I let Gabrielle come to our dormitory to find trouble?"

He thought Jon was dissatisfied with him for taking matters into his own hands, but Jon shook his head decisively.

"No, you are right to dissuade her. Although she is only seven years old, she should be taught the difference between men and women at this time."

"Then why are you looking at me like that?"

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

Neville was stunned for a moment, then asked with a solemn expression.

"What evil spell has been cast on you? Do you need my help to solve it for you?"

"No, I want you to help cast a curse on me."

There was a brief silence in the dormitory. After four or five seconds, Neville stared at Jon with a strange look.

"You're crazy!"

"I'm very rational." Jon didn't explain too much to him, but just continued, "This is just a small experiment. You will definitely not harm me, and I'm not stupid enough to harm myself. Use your best skill on me." Spells, curses and curses are all fine."

Neville has a high level of trust in Jon, and with the lessons learned from last year's levitating spell, he also knows that Jon will always come up with some weird and unconventional spells.

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

"Is the petrification spell okay? I haven't come across any evil spells, but I got familiar with it when you were studying the petrification spell last year."

"No problem." Jon naturally had no objection.

Neville didn't hesitate anymore, he raised his wand at Jon, and Jon didn't take any protective measures.

"Everything is petrified."

The red beam shot out from the tip of Neville's staff and hit Jon's body straight.

But this spell was like a stone sinking into the sea, without causing any splash. Not only was the petrification effect not reflected at all, but even the impact that should have been attached to the spell disappeared.

Neville blinked his eyes hard. He guessed in advance that Jon might be conducting some magic research, but he didn't expect that Jon had taken a petrification spell from him, and his body didn't even sway!

Jon and Neville are roommates, so he naturally knows that Neville's magical power is stronger than Ron, Justin and Lavender, but slightly inferior to him.

Therefore, Jon expected that the breaking spell on him would be effective, and the key to the problem was the gem in the ring.

Without immediately going to explain to Neville why his petrification spell had no effect at all, Jon took the ring in his hand again and carefully observed the color of the second gemstone. He vaguely felt that this gemstone was darker than the previous one. It's a little deeper than can be detected.

After that, he calmed down to feel it, and indeed he detected a trace of free magic power in the gem.

And this magic power obviously belongs to Neville!

It's just that the magic power is so weak that if Jon isn't careful, he may not even be able to sense it.

Compared with when he first got this gem when it was still deep red, the difference between a drop of water and a river was as big as that.

However, Jon's focus was not on the magic absorbed by the gem. He carefully observed the gem and always felt that the magic obtained from Neville's petrification spell had a book attached to it. Book title.

The content of the book could not be seen, and it was unknown how thick it was. It seemed that Neville's magic could only make it show through the cover.

It took a lot of effort for Jon to finally read the title of this book clearly:

"The Invisible Blade: The Shadowless Blade"

Under the title of the book, he also saw a familiar author's name - Severus Snape!

Thank you to the leader who has forgotten the password for the reward. According to the statement when it was put on the shelves, the leader will add five updates. However, I am currently on a business trip and have no time to write more. I will add more updates when I get home this weekend!
