"Albus, how can you show Ryan such a dangerous book of dark arts? Professor McGonagall's angry voice could be heard from the Headmaster's office. After deciding to make an unbreakable oath, Dumbledore chose Professor McGonagall as a witness, but Professor McGonagall immediately expressed her grievances when she learned of the contents of the oath.

"Minerva, a lot of innocent lives are at stake. Dumbledore looked at Professor McGonagall and explained earnestly, "I know this knowledge is very dangerous, but it's safest. ”

"The safest thing to do?, Albus, I don't know when we're going to need to put such a young kid at the front?" Professor McGonagall asked angrily after listening to Professor Dumbledore's explanation.

"I don't want to do that either, but I think Ryan is no longer an ordinary kid, he has the will and the strength to solve this problem, and now he is the only one who can solve the problem we face. ”

"Yes, Mr. Headmaster is right. Ryan also nodded beside him. "It's all voluntary, please help me!"

After being persuaded by Ryan and Dumbledore, Professor McGonagall finally became willing to be the Witness. After she nodded, Professor Dumbledore stood up from his chair, then walked around to the table and took Ryan's right hand with his right hand. Professor McGonagall took her wand from her body and placed it on both of their hands.

"Ryan, would you like to never use the dark magic of Horcruxes?" asked Dundedo.

"I do. Ryan said. As soon as he spoke, a thin, dazzling tongue of fire erupted from Professor McGonagall's wand, like a red, hot wire, wrapped around their two hands.

"Are you willing to do your best to keep these secrets and keep this evil knowledge from passing through you? ”

"I do. Ryan said. A second tongue of fire erupted from the wand, intertwining with the first, forming a thin, red-glowing chain. Like a rope, like a snake in flames.

"Then, the oath is made. Professor McGonagall announced that the chain of flames that had been wrapped around Ryan and Headmaster Dumbledore disappeared in an instant, indicating that the oath had been established.

"Okay, you can read the book now. As soon as Professor McGonagall left the Headmaster's office, Dumbledore pulled out a black book from a locked drawer that covered the corners and spine of the cover and handed it to Ryan, then continued, "But for security reasons, you can only read this book in my office, not take it out." ”

"Got it, I should be able to finish this book in no time. Ryan said as he took the book with both hands, only to find that the book was only a thin one, and it definitely didn't feel like parchment.

"Is this—a human skin book?" After touching the cover of the book, Ryan recognized the material of the book. Because he'd seen more than one human skin when the Fallout World was cleaning up those mutant marauders.

"Yes. Dumbledore nodded. "This is the human skin that the author made after digging up a dozen graves, because in the past it was thought that this kind of soul-related book was best recorded on human skin, and it was still in the forbidden section of Hogwarts a few decades ago, but I put it away after Voldemort made the Horcruxes. ”

"Doesn't sound too bad. Ryan shrugged, it was much better than skinning a mutant in the Fallout world, and Ryan understood Dumbledore's way of putting the book away. It's like for security reasons, there are no detailed process flow charts for certain weapons or some terrible medicine in the library of a university.

Therefore, Ryan felt that there was no need to be like the victim paranoia, and always felt that as long as the principal put away certain books, he would suppress the juniors. The ones who really want to suppress the students are the pure-blood families who read their own books at home and would rather keep the books rotten at home than take them out.

After thinking about all these miscellaneous things, Ryan began to take a closer look at the book. It was only then that he discovered that the original book had gilded letters on the cover, but now it had all been eroded by time.

"The Road to Eternal Life" Ryan spelled out the Latin title by the light in the headmaster's office, and although the title was boastful, he had to admit that Horcruxes were indeed a genius idea. It's just that this defect of eternal life is too great.

Upon opening the book, Ryan found that it was a manuscript. The scribe used magic ink mixed with dragon's blood and mandrake juice to confirm that the book would last for a long time. In addition to the main body and some illustrations, the experiences of the readers in the margins between the lines allow Ryan to see the history of Horcrux making.

Horcruxes originated from mummies in ancient Egypt, where ancient Egyptian wizards used magic to cut off parts of their bodies and raise them into another body of their own, so that when their bodies were irreparably damaged, the soul would abandon the damaged body and use this pre-prepared spare body to resurrect. The magic was later known to the Muggles, but they were unaware of the specifics. Therefore, there is a local custom of mummification, and it is said that mummies can be resurrected.

Later, as this magic spread, some wizards who wished to gain immortality improved the magic. Improved magic does not require a spare body to be raised into a human form beforehand, so it can be hidden in a small release box, which greatly increases the concealment. At the same time, the biggest difference from the previous one is that at the same time as a part of the body, a part of the soul is also cut out through complex magical means.

In this way, the effect of the passage of time on the part of the body and soul protected by the special magic container will be suppressed to a minimum, and the connection between the soul fragment and the soul body will feed back this situation to the subject, allowing the subject to gain a long life. At the same time, as long as the container is not found, then the wizard cannot be killed. It's just that their minds will be irreversibly damaged every time they are resurrected, so the number of resurrections is also limited.

And in modern times, this magic has been improved again. Complex soul-cutting magic is replaced by killing, and at the same time, it is no longer necessary to cut off a part of the body, only the soul. That's how the real Horcrux crafting method came about.

Although this greatly lowered the threshold for the production of Horcruxes and simplified the production process, it also caused serious consequences. On the one hand, it completely transforms the original neutral magic into an evil black magic, so that the user's body will take additional damage when facing magic such as thunder or holy light.

On the other hand, after the original body is destroyed, it cannot be resurrected directly like the previous two methods, but it is necessary to recreate a body through other means.

However, even this simplified version of Horcrux making is actually far beyond the knowledge of a normal wizard. Ryan had learned from his time in multiple worlds, and Voldemort was a true genius as an orphan who could understand them just by living at Hogwarts for six years in contact with the wizarding world.

If nothing else, this amount of time alone is very powerful in learning Latin to a high level. Ryan felt that he would never have been able to do this if he hadn't taken out the goldfinger.

It took Ryan a full five hours to put down the book "The Road to Eternal Life" in his hand, thanks to the previous upgrade of his strength, his memory and comprehension ability have taken a big step up, so that he can finish reading this book in a short time.

"I think I've got a bit of a clue. Looking at Headmaster Dumbledore, who was looking at him with concern, Ryan nodded and said. "I need time, though. ”

"It's already good. Headmaster Dumbledore put away the book, "Don't be impatient, we'll have plenty of time to wait." If the cost of saving an innocent life is another, then such a salvation is completely meaningless. ”
