Life has to go on, and when the little turmoil subsides, it will go back to the past, and people have become accustomed to Saul's elusiveness, to the fact that Saul does not see anyone after his daily class, and to the absence of him in the Ravenclaw common room.

And if you want to find Thor, go to the library! However, this is also a matter of probability, and Thor comes to the library less often than in the past.

Every time I appeared, I would return a pile of books with me, and then, borrow a large stack of books. Lately Thor has focused on herbs, magical creatures, and potions, which are similarly unattended tomes, monotonous and drowsy.

But Saul's face never revealed tiredness, he was always so calm.

The clever Hermione looked at the long potion formulas and the awkward explanations, and really admired Thor for reading this kind of book, and seemed to understand and read it happily.

Time flies quickly, half a month is about to pass.

After concocting a lot of potions to enhance his physique and increase his magic power in the Room of Requirement, Thor began to prepare the expensive invisibility potion.

It took seven nights for Thor to make the potion colorless and transparent, the kind that could be eaten.

It was a pot of invisibility potion, and that night, Thor drank the potion, and then he went straight to the forbidden book area.

Since that day, he has been hearing the books as soon as he approaches the forbidden area. They whispered to Thor to come to the forbidden section, where they would teach him the knowledge he had always dreamed of.

Thor, who has learned three unforgivable spells, will of course go to the appointment of the forbidden books.

The moment he stepped into the forbidden section, the books began to whisper again, telling Thor not to be afraid, not to worry, to believe in yourself.

However, Saul looked at the spine of these books one by one, and he pulled out a copy of "The Secret of the Soul", a book that had not been very quiet, and in Saul's hands, it was unusually quiet. It could feel the magic in Thor's body, how compatible it was.

"The weight of the soul is only 0.74oz, but what it can carry is a person's life." This sentence on the title page made Saul agree.

This would have been a good fit for Thor, it didn't have a single spell, it was all theoretical research. This was exactly what Sol was missing, so Sol forced the table of contents of the book to be written down.

Then, he flipped through some more books, and there was one book written entirely in psychic language about necromancy, which made Thor excited!

He had been looking for books about necromancy, to determine if it ever existed and if it had ever been brilliant. But now, the book in front of him gave him a definite answer.

The Golden Age, it was the time when books in the forbidden area were glorious. They used to be in bookstores, in libraries, and were read, studied, and added to by generations of wizards.

However, due to the constraints of the spell casting, the fact that they require strong emotions, and the high probability of harming innocent people, it has declined.

He took out his wand and looked at his wand, it was also excited! This is supposed to be its field of expertise, and it is also calling for Thor, use it quickly, and cast the magic here!

Thor's no, Thor kept walking in, walked to a book bound in chains, raised his wand, and read in psychic language, "If there's anything you want to say to me, please show up!" ”

A face appears on the cover of the book, and it speaks, also in the psychic language: "I do have something to say to you, I'm sorry, I made a mistake more than fifty years ago." I've taught some dangerous things to a boy about your age and talent. That young man, who violated the agreement between us, wreaked havoc and used cruel means to try to rule the wizarding world. ”

Later, the boy also changed his name, and he also added a curse to his current name, and all the people who pronounced his current name could feel it within a certain range of his surroundings. People were afraid of him and called him the 'mystery man'. ”

"So I was chained and sealed here. If you want to look at me, you need to make a vow to get rid of that 'mystery man' and not to do evil with everything you have learned. Your eyes are beautiful, and you want them to be clear and clear forever. ”

Thor took a deep breath, "Okay. I take the name of Thor, the Child of Shadows. In Sreit's name, I swear never to do evil with the magic I have learned. My magic is not aimed at my friends or relatives, but only at my enemies. I will use the magic I have learned to get rid of Voldemort and his minions, and bring the glory of the Golden Age back to life! If I break my oath, my soul and my life will no longer belong to me. ”

Thor's wand emitted a burst of gray light, and there was a gray skull mark on his arm. On the other side of the light, there was the book, the book, which was opened in a hurry to the light.

This book, which deals with the spells of soul magic, complements the previous theory.

And the last few pages of this book record the method of making a soul box that has been lost for thousands of years! Thor hurriedly copied down the pages.

Split the soul, and then put the soul fragment into the soul box, and after the soul box is successfully crafted, it will disappear and be stored in the maker's body. If the maker dies, the crate will not appear. If you want to resurrect the maker, you can find a place where you can hold a séance ceremony, start the ritual, and resurrect the maker.

It's just that from the moment the production is successful, the maker is no longer a human being, but an existence called a "lich". However, the success rate of the production is only 5%.

When Thor had finished copying it, he put it back in its place, thanked him, and continued on his way. Blood magic, well, is not for him.

Demons and summoning? He wasn't going to make any pact with the demon, so he didn't think much of it.

Thor finally stopped in front of a book about curses. Curses, mysterious rituals, this is something that Thor lacks, don't look at Thor learned three unforgivable spells, he can't even send a "broken bone" now! It's too watery, too unworthy of its name!

Thor, who was very happy to read the book in his hand, didn't notice at all that the person he didn't want to see was right next to him, and he was also intimate, providing him with lighting.

It wasn't until he finished reading it that he realized that the smiling Headmaster, Professor Dumbledore. "Ahh Good invisibility potion, I used to linger here when I was younger. Dumbledore looked at Thor, who was panicking.
