Professor Dumbledore had been very busy for a month after Professor Slughorn's feast, and Ryan had met the Headmaster twice during the meal, and each time the Headmaster had left early after a hasty meal.

However, one day when he returned to his dormitory after class to rest, he received a letter from Dumbledore, stating that Ryan needed to be fully prepared recently, as he had found the possible whereabouts of an object that could be Voldemort's Horcrux, and that he might need Ryan's help when he went to get it.

"The headmaster is really cautious. Watching the letter burn to ash in front of his eyes, Ryan muttered quietly in his heart. He could understand Dumbledore's thoughts, a person who could return from the dead world would not be too weak in any way, and with Dumbledore's personality, he had to make sure that such a person who could produce unfavorable variables could not negatively affect his plans. And this time to call Ryan out and destroy the Horcruxes with him, on the one hand, it does require the help of Ryan's alchemy knowledge, and on the other hand, he must want to assess Ryan's camp and attitude towards Voldemort.

Anyway, Ryan doesn't have any plans to rule the entire wizarding world, just because he manages a lot of worlds, so he won't add a burden to himself. So he quickly replied with a note that said OK to the principal. In fact, the current situation of Dumbledore being in the forefront is Ryan's favorite, as for transforming the wizarding world, since he now has a long lifespan, it is the best way to subtly change this world in two or three hundred years, there is no need to be so impatient.

However, after writing back to the Headmaster, Ryan never heard from Dumbledore, and the only special thing during this time, apart from classes, was that he and Hermione attended two more small dinners with Slughorn. I have to say that Slughorn is a person who knows how to live, the food at the dinner is very good, and it can make people relax a little in the current oppressive atmosphere, according to Hermione's evaluation is "This dinner will not be as bad as Harry said, sometimes it is quite funny, I really don't know why Harry didn't come, he is the most in need of relaxation among the people I know." ”

Ryan could only shrug his shoulders, he and Hermione were just accompanying guests now, and it was enough to take care of themselves and relax during dinner. But Harry was Slughorn's key observer, and it was really better to practice Quidditch in the wind and rain than to rack his brains to avoid Slughorn's overtures after a meal.

It wasn't until mid-October that they were allowed to go to Hogsmeade for the first time this semester. Looking at the increasingly tight defenses around the school, many people thought that they would not be allowed to go to Hogsmeade Village. Now that they knew they were still going, everyone seemed happy. In the current oppressive atmosphere, it is pleasant to leave the castle and relax, even if it is only for a few hours.

On the morning of his trip to Hogsmeade Village, there was a strong wind outside, and Ryan got up early to pack his belongings, because he had informed Lupin two days earlier to bring two werewolves directly over today, taking advantage of this Hogsmeade day opportunity to complete their treatment in one go. Recently, Healer Ryan has figured out a lot about the rules of change from the transformation of these two werewolf forms, so he plans to challenge himself by increasing his workload in the next few days.

Ryan took a little more time to sort out the potion, so when he came to the table, he saw that it was already full. When he finally found Hermione, he found Hermione glaring at Harry.

"What's going on?" Ryan asked Ron, who was watching the excitement.

"Well, this morning I was sleeping when I felt a bright light, and then a magic hooked my feet and neck, and hung me upside down. Thankfully, there was another flash of light, and I fell back into bed!" Ron said with a grin to Ryan, who thought it was just a joke. "So you advise Hermione, she's making a fuss. ”

"Kidding?" Hermione turned her head sharply to stare at Ron, looking like an angry lion. "Percy told me before that the Death Eaters in the last war liked nothing more than to hang people in the air, leaving them groggy and powerless to float on them. You tell me this kind of magic is a joke?"

"Alright, Hermione, don't get excited. Ryan pressed his hand lightly on Hermione's shoulder. "Death Eaters are just abuse, and you have to know that even the simplest levitation spell can hang their victims in the air, and then lift the spell to tear them apart. This magic should be prank-pranking magic at best. ”

"Look, I'm right—" Ron said with a grin, "Hermione, you're overly sensitive sometimes. ”

"No, actually, Harry, your fault isn't small. Ryan looked at Harry, who had just shown a relaxed expression, "How can you rashly release a spell on a friend that you don't know anything about?

"Probably not?" Harry said, glancing cautiously at Hermione's angry face, "I used to think he wrote something very normal. ”

"No, no, no, you must know that this book is a textbook for sixth and seventh graders, and wizards who can improve on the textbook must be very good academically. Thinking of Harry's bullish temper, Ryan decided to try in a different direction.

"You have a point, but what does it have to do with the magic inside?" asked Harry, looking suspicious.

"It's normal for such an excellent student to choose the Defence Against the Dark Arts class, and the senior students can apply to watch the dark arts in the forbidden area while studying the Defence Against the Dark Arts class. What if this half-blood prince borrows a certain dark magic book and writes down a few dark arts in his textbook to make it easier for him to learn?"

"It's—" After listening to Ryan's words, Harry felt a cold sweat break out on his back. With a hint of luck, he asked, "Is anyone really in the habit of recording spells?"

"There are quite a few people who have this habit, at least I have. Hermione nodded, took out a small notebook from her small satchel, and then flipped through it and pointed to a few pages. "In order to learn Defence Against the Dark Arts, I recorded a lot of dark arts. You see, these two pages are about the use and principles of the Gut Extraction Charm, and this half is the technique of using the Bone Crusher Charm—"

"It's horrible. Ron swallowed a mouthful of spit and said, "What about you, Ryan?"

Ryan looked at the left and right and saw that there was no one else, and pulled out half of a book from his space bag. Harry's eyes widened at the sight of some of the peeling gold titles, as it was a copy of the Common Dark Arts.

"How could you—" Before Ron could finish speaking, Ryan pulled out a note with Professor McGonagall allowing Ryan to hold at the school and study the book.

"You know I've been supplying the Order of the Phoenix with alchemy products, how can I make something that can defend against them if I don't know the principles of the dark arts?" Ryan's reply made Harry and Ron suddenly realize. Backed up by this evidence, Harry promised that he would copy out all the spells in his textbook when he returned, and let Ryan and them help check them before using them.

Although this assurance was a bit different from Hermione's imagination of Harry handing in his textbooks, she felt that it was only a great victory. On the way, Hermione smiled and said to Ryan, "You can actually convince Harry, you must know that what I just said for a long time is useless." ”

"It's nothing, except that the hard-handed persuasion style you've been used to since your first year doesn't quite suit Harry. Ryan pulled his neckline as he spoke, and now that the castle was full of wind, rain and snow, if he hadn't promised Lupin today, Ryan would have chosen to rest in front of the burning fireplace in the common room.

Harry, Ron, and Ginny estimated that it would be a while before they could come to Hogsmeade, as they had been told that Harico Linklevy was looking for him while they were in line to get out, so the three of them went straight back to the castle.

Hogsmeade Village is much more depressed than it used to be, but fortunately, the Duke of Bee's Candy Store and the Weasley Joke Shop Hogsmeade branch on the left and right at the entrance to the village are still full of students.

"I'm going to treat those werewolves first, do you want to walk around town?" Ryan asked Hermione as she stood at the entrance of the village.

"I'd better go with you. Hermione pulled Ryan toward the Weasley Joke Shop, Hogsmeade.
