This is a very well-known black magic in today's magic world.
As Voldemort's right-hand man today, Snape invented and created several dark magic and magic potions, which have been widely spread among Death Eaters and Aurors.
Shenfeng Wuying is one of them.
Its status in the minds of those Death Eaters who have destruction almost engraved in their bones is enough to rank alongside the Explosive Curse as the most useful offensive spell among the three Unforgivable Curses.
The casting speed is fast enough, the hit rate is extremely high, and the damage can be strong or weak according to the wizard's mood. The damage caused is also accompanied by a curse, but it is not such that it cannot be cured.
This spell was not hidden by Snape, and it was impossible for Voldemort to let him keep such a useful dark magic secret. He wrote all the keys to learning this spell in a book, so as to teach the Death Eaters
Broad dissemination of learning in groups.
It is reasonable for this book to be included in the restricted book section of the Hogwarts Castle Library.
What appears in Jon's mind now is a book written by Snape.
Jon is very excited.
The source of his excitement was not only the discovery of the book "The Invisible Blade: The Shadowless Blade", but also the fact that the book cover that appeared after the absorption of Neville's magic power told him that the book that was originally stored in the Hogwarts library
The knowledge stored in the magic power absorbed by the gem did not disappear just like that!
Magic is a carrier, but not the knowledge itself. As long as the gem is "charged" and filled little by little, Jon will be able to obtain more than 80% of the information originally hidden in the restricted book section of the library.
Magical knowledge.
Hogwarts is the oldest magic school in Europe, and its collection of books is also the most comprehensive in the European wizarding world, and the forbidden books are undoubtedly the most profound and dangerous among the knowledge recorded on paper.
Now more than 80% of the content in this part is in this gem, which means that Jon has a library of magical forbidden books that he can carry with him.
The key to opening this library is the magic power of different people!
The stronger the magic absorbed, the more magical knowledge he can gain.
Just like now, Neville's magic power helped him present the cover of the forbidden book written by Snape. As long as he collects more magic power, he will obtain the entire content of the book!
Jon couldn't wait to put on a coat on himself. He looked at Neville who was still dazed and asked.
"Ron, are they still in the common room?"
Only then did Neville come to his senses.
"They should still be there. When I came back, they were helping to tutor Hermione and the other new students in transfiguration. Why did my petrification spell just fail to work on you?" He couldn't help but ask in the end.
"The universal breaking spell is a spell we should have learned in the third grade. It has a dispelling effect on most magics, and the petrification spell is no exception."
"But... I clearly saw that you didn't make any move to cast a spell?" Neville asked the biggest doubt.
Jon walked up to him and did not lie or hide anything.
"Do you still remember the floating spell I used in front of you at the beginning of last year? This spell is just like the floating spell I learned at that time, but it is slightly different."
When he said this, he seemed to suddenly think of something, looked at Neville and asked.
"Did you find the book I asked you to go home to find last year before the summer vacation? About universal gravitation and Newton's laws?"
Neville nodded and said.
"I asked my father to help me go to a Muggle bookstore to look for it in my free time. He bought a few books like this, but..." He scratched his head in embarrassment, "But I can't quite understand what's written in it.
What is it."
If you just simply understand what gravity is, this may not be difficult, but it is not so easy for wizards who have been exposed to magic since childhood to accept this kind of knowledge from their hearts.
Moreover, Neville's father did not necessarily buy him a superficial introduction to gravity-related popular science books. It might involve deeper electromagnetic forces and force fields.
Prestige must be like a heavenly book.
So it may not be an easy task for him to start from scratch.
Jon wanted to try to change the will and thoughts when casting spells to achieve different effects of the same spell. Can this be implemented on other students?
If it proves that this can be practiced by everyone, then Jon feels that this change in spellcasting must be very promising, and it is very suitable for these students in the carriage.
Most of them are of Muggle origin. Before being taken to magic school at the age of 11, they all had primary school education experience. This may not allow them to learn such detailed knowledge, but at least they have a theoretical basis in natural science.
, much better than Neville who has never been exposed to it since he was a child.
Moreover, in this year's Hogwarts, there is a girl who was rescued from the castle by him. In the original book, Dumbledore personally admitted that she had rational and logical thinking abilities that most wizards did not have.
It was difficult for Neville to get started with his knowledge of natural sciences, but that would not be a problem for the girl.
Leaving the dormitory, Jon went straight to the common room.
Only Lavender and Hermione are still here to study the history of magic, and everyone else has gone back.
After the students in the castle arrived at the carriage, Lavender was finally not just a girl among the second-year students.
She used to live in the same dormitory with third-year girls, but now she can naturally be assigned to live with second-year girls.
Hermione is her new roommate from this year until graduation.
It was almost 10 o'clock. They also packed up their books and parchments and stood up to leave the common room. They happened to meet Jon who opened the door and walked towards them.
"Good evening, can you do me a little favor?"
He greeted the two girls.
As long as it was a spell that could be erased by the breaking spell, it would be the same to Jon no matter what the spell was. Because the students' magic was still too weak, he could only use quantity to make up for quality, and try to find as many people as possible to absorb the magic.
Although the magic power of the professors is strong, his breaking spell cannot block the magic spell used by any professor, which means that the magic power of the spell cannot be stored in the gem.
Of course, if you directly consume the magic power in the gem to use the breaking spell on yourself, you can increase the power of the breaking spell, but this is putting the cart before the horse. If all the stored magic power is used up, what is the use of strengthening the breaking spell?
Using the excuse of conducting a spell experiment, he asked Lavender and Hermione to help cast spells, and of course the two girls did not refuse.
And just after they satisfied Jon's needs and the magic power was absorbed by the gem, Jon stopped Hermione alone.
"Are you free at noon tomorrow? I have something related to magic that I want to talk to you about."
