Usually there are not many people in the common room after dinner in the evening, and most of them have their own things to do. However, today, after Ryan finished studying Shen Feng, he noticed that the surroundings were a little noisy, and after looking up at the common room, he realized that the people who were chattering here were all sixth-year students.

What made everyone excited was a new notice posted on the bulletin board informing them of the date of the Phantom Apparition exam. Before the first exam (21 April), students who have reached the age of 17 can register for special training in Hogsmeade (strictly supervised).

This matter has nothing to do with Ryan, because his birthday is in May, and even if he is skilled in apparition now, he will have to wait until the second exam. He was joined by Harry, though Harry took the exam later, not until July.

The unluckiest of all was Ron, who was the oldest in this place. However, age did not give him an advantage in the illusion, as he had not succeeded once in class. He was not as good as Harry in that regard, at least in the last lesson, Harry had successfully appeared in the wooden circle for the first time.

After figuring out the dangers of Bladeless, Harry began to think hard about how to get Slughorn's memories. In yesterday's discussion, he had learned from Hermione that there was only one way to force someone to do what you wanted them to do, and that was the Imperius Curse.

However, Ryan told him that at his level, he couldn't control Professor Slughorn. So it is not advisable for him to use this stupid method.

Harry had to admit that Ryan's judgment was right, the person who could be the head of the Slytherin head in Hogwarts for a long time definitely belonged to the top wizards in the wizarding world, and it was definitely not something that an adult young wizard like himself could control with a Imperius Charm.

"Ryan, do you really have no magic or potions that can pry Slughorn's mouth open?" said Harry as he stood up and walked over to the table where Ryan and Hermione were sitting again.

"Not really, Harry. Ryan said helplessly. "Unless we can truly control Slughorn, there will be a glimmer of hope for some irreversible and dangerous means to be taken—" Ryan slapped Hermione's hand violently.

"Harry, don't listen to Ryan's nonsense. Hermione glared at Ryan and turned to Harry. "Dumbledore said that only you can get that memory, and that must be saying that you can convince Slughorn and no one else can't. It's not a matter of giving him potions or using spells, if that were the case, Professor Dumbledore would have done it himself, and he wouldn't need you at all. ”

As time went on, there were fewer and fewer people in the common room. It was only after Harry reluctantly closed the half-blood prince's potions book that he realized that he was the only ones left in the common room, Ryan, Ron, and Hermione. Ginny had finished her homework and gone upstairs to rest three minutes ago, because Ginny was going to participate this year. LS exams, so she is also very busy.

At this moment, there was a sudden crackling sound in the empty common room. Dobby appeared in front of the three of them, his hat crooked to the side. Harry Potter said that he would report Malfoy to him often, so Dobby came to Harry Potter to report on his observations. ”

"And did you find me now because you found something?" asked Harry eagerly.

"Draco Malfoy is a bad boy!" Dobby screamed angrily, "a bad boy, he-he-"

At this point, Dobby shuddered from the tassel of the teapot cover to the tip of his sock, and then he rushed to the fire, as if to jump in. Luckily, Ryan caught him quickly.

After a few seconds of dancing and struggling, Dobby relented and thanked Ryan. "Thank you, Dobby still has a hard time saying bad things about the old owner......"

"It's normal, and you may need to get used to it. Ryan said after placing Dobby on the ground. "Well, if you have any new discoveries, please speak up, that's the key. ”

"That's right. Dobby looked at Harry with wide eyes. Dobby didn't notice Malfoy breaking any rules, but he was still careful not to be caught doing what he did. He often took different students to the eighth floor, they put a sentry on him, and he went into the room of requirement. ”

"I should have thought of it. Harry slapped his forehead with the palm of his hand. "Most of Hogwarts is visible on the Vital Map, except for the Room of Requirement that I've never seen on a map. I should have thought of that, by the way, Dobby, did you see what Malfoy was doing in there?"

"No, Harry Potter, it can't be. Dobby said.

"Obviously last year Umbridge, they-" Harry asked curiously.

"That's because you had a whistleblower last year. Ryan said. "The Room of Requirement actually has the effect of a secret room, and you think that before the secret was told, neither Filch nor Umbridge spent so much energy and finally didn't find you. And now we don't know what the room was like when Malfoy entered, so naturally we can't go into the place he entered before to see what he was doing. ”

"There will be a way," Harry said with a look of confidence, before he bowed his head. "You're doing a great job, Dobby. ”

"Thank you, Harry Potter, sir!" Dobby squealed happily, then picked up a small leather bag and handed it to Ryan. "And Mr. Ryan Leung, thank you for giving me these magic items. Otherwise, I'd probably have to follow Malfoy for days and nights without sleep. ”

"Nothing, that's what I'm supposed to do. Ryan took the bag, and Dobby bowed to Ryan before leaving.

"I think I know what the situation is, maybe I'll be able to catch Malfoy right away. Harry said with some excitement. "Just wait for Malfoy to block Malfoy when he enters the Room of Requirement. ”

"Sounds good, but we're still too few of us. Ron pointed out keenly. "Don't forget that Dobby said that Malfoy always brings a different person with him, and if Malfoy is in a party with a group of people, not only will we not know what kind of conspiracy he is having, but it will also be easy to make him vigilant. ”

"You don't have to worry about that. Ryan thought for a moment and said, "According to Harry's previous statement, Malfoy is engaged in a huge conspiracy. Not even Snape told him. I don't think he's going to find a large group of people to do something in this situation, because the more people involved in a conspiracy, the more likely it is to have problems. ”

"And what do you think that's going on?" Ron asked, puzzled.

"I guess it's a polyjuice decoction. Ryan explained. That would explain what was going on, he should have actually been looking for Crabbe and Goyle, just letting them drink a polyjuice potion with different people's hair. ”

"That's true. Harry's eyes widened. "Malfoy is so cunning that he doesn't even want people to see Crabbe and Goyle always there, causing suspicion. And when we had our first potions class, there was a whole pot of polyjuice potion in the class, and he could easily get the medicine he needed from it. ”

"So the two little girls I saw with Malfoy were Crabbe and Goyle?" Ron said and laughed, "God...... No wonder they haven't been happy lately...... disguised as a girl......"

But his laughter soon diminished, as Ryan looked at him with an unhappy face.

"Alright, let's get down to business. Ron grimaced. "Why would the two of them listen to Malfoy? ”

"All it takes is Malfoy to show the Dark Mark on his arm. Harry said excitedly. "Officially, the Death Eaters will have some appeal from the Slytherin thugs. ”

"Harry, now you need to pay attention to the most crucial memory, which is the core of the victory over the mysterious man. Ryan said as he cleaned up the table. "And Malfoy, I'm sure he wouldn't have done much harm with the headmaster's control over the school. ”
