Bringing the little wizards back to the Gryffindor common room, the portraits that had been sent out by Professor Dumbledore to find the Fat Lady had also returned.

"Professor Dumbledore, the Fat Lady is right..."

"I've already found her, thank you all for your help."

Professor Dumbledore smiled in gratitude, then waved his wand to open the door to the Gryffindor common room and walked in with the wizards of Gryffindor.

"Alright, children, everyone has been a bit frightened tonight."

He looked gently at the little wizards in front of him and cast a protective spell with his wand.

"Now, just settle down and get a good night's sleep. No one will be able to come in and disturb you, at least not Black."

"Thank you, Professor Dumbledore."

The Gryffindors politely expressed their thanks. Professor Dumbledore put away his wand and nodded to Professor McGonagall, and the two of them prepared to leave with Lin Yue, Hermione, and Cho Chang.

Harry and Ron exchanged a glance and stepped forward together. "Professor Dumbledore, we want to listen in too."

Harry pressed his lips together and added, "After all, Black's target is me, isn't it? Maybe if I hear it, I can be a bit safer."

"At least I'll know how he might lurk around me."

"Albus..." Professor McGonagall frowned, looking uncertainly at Professor Dumbledore.

She knew Harry was right, but deep down, she really didn't want the kids to be involved in these matters.

"Let them listen in, Minerva. Harry and the others have the right to know."

"As he said, Black's target is him, isn't it?"

"Alright," Professor McGonagall nodded, turning to look at Harry and Ron. "Come on, Mr. Potter, Mr. Weasley, you can all join."

"Considering that even if only Mr. Potter listens, he will tell you afterward."

Harry's face turned red for a moment, and he coughed lightly, while Ron awkwardly smiled along. The group walked out of the Gryffindor common room and arrived at the headmaster's office.

Headmaster Dumbledore waved his hand, preparing a cup of hot milk for each of the seven children. "Please sit down, ladies and gentlemen. Since it's almost bedtime, I won't serve you tea."

"Thank you, Headmaster Dumbledore."

The seven of them exchanged glances, took a deep breath, and sipped their milk. Hermione's eyes widened in disbelief.

There was no lethal dose of sugar added!

Dumbledore shook his head at the children's expressions. "As one gets older, one tends to need more sweetness to dilute certain things, but clearly, you children do not need it. I’ve just come to realize that."

"Uh, thank you, Headmaster Dumbledore."

Hermione, realizing her expression was inappropriate, quickly adjusted and said thank you.

Lin Yue put down her milk and stared intently at Headmaster Dumbledore. "Sirius Black is an illegal Animagus."

"Cough cough cough..."

Coughs echoed in the headmaster's office, with Harry and Ron gasping for breath, while several girls, including Hermione, looked at Lin Yue in shock. Even Professor McGonagall exclaimed that it was impossible.

Since Lin Yue had mastered becoming an Animagus, everyone presents, including Harry and Ron, had a certain understanding of what it meant to be an Animagus. This understanding naturally included how to become one, and the conditions for becoming an Animagus were too complicated and too harsh.

It was almost impossible to do so without attracting attention, let alone at Hogwarts.

That's why everyone was so astonished, even Professor McGonagall couldn't believe it.

"Well, it's not entirely impossible," Headmaster Dumbledore stroked his beard. "Even as professors, we can't claim to know everything about our students."

Professor McGonagall frowned, "It's easy to say that, but an Animagus... Merlin, if that's the case, then they were really bold back then."

"Miss Lin Yue, may I ask how you came to this conclusion?"

This book was originally published on Royal Road. Check it out there for the real experience.

Headmaster Dumbledore slightly lowered his head, looking through his glasses at Lin Yue, who was sitting on the sofa with an expression that showed no change.

"Of course." Lin Yue nodded indifferently.

"According to Harry's account, he saw a large black dog by the roadside when he left his aunt and uncle's house."

"And later, in Diagon Alley, I noticed a large black dog following us. It would hide itself in a nearby alley when it noticed the crowd, which is something a normal dog cannot do."

"Therefore, I can basically deduce that the large black dog is an Animagus, an illegal Animagus."

"Sirius Black escaped from Azkaban. It is known that those who go to Azkaban have their wands taken away, and with the presence of Dementors, their magic is suppressed."

"The only possible explanation is that he has practiced becoming an Animagus, allowing him to transform without a wand and escape under the watch of the Dementors."

At this moment, the office was silent; apart from Lin Yue's voice, everyone else had quieted their breathing, and one could hear a pin drop in the headmaster's office.

"Furthermore, today, Sirius Black successfully entered the school past the Dementors guarding Hogwarts. Combining this with the analysis above, we can conclude that Sirius Black is indeed an illegal Animagus."

"And there is a seventy-five percent chance that he is the large black dog that has appeared beside Harry twice, with the clear target being Harry."

"Merlin's large black dog..."

Ron whispered with a trembling voice, turning to look at Harry, "So that means you had already met with Black alone when you left your aunt and uncle's house."

"That's too dangerous..."

"But that doesn't make sense," Harry frowned and shook his head, "If that were the case, then the later encounter is easy to explain; in Diagon Alley, there are too many people, and he wouldn't be able to act against me."

"But what about the first time? I was alone, and it was on a Muggle Street at night; no one would be able to stop him. Why didn't he act against me?"

"That is indeed a point of suspicion," Lin Yue turned to look at Harry with a blank yet steady gaze, "Therefore, I believe the claim that Sirius Black wants to kill Harry is questionable, but there is no doubt that his attention is on you."

"I really am, welcomed by trouble," Harry said with a slight twitch of his mouth, self-deprecatingly.

"An excellent and reasonable analysis, Miss Lin Yue."

Principal Dumbledore took off his glasses and wiped them, slightly lowering his head as if he were deep in thought. Knowing the "truth" of the past, he seemed to have picked up on something else from Lin Yue's analysis, combining it with those so-called truths.

"Albus, but isn't Black supposed to...?" Professor McGonagall didn't finish her sentence, mindful that Harry was still there. However, Principal Dumbledore understood her meaning. He raised his hand and waved it dismissively.

"Perhaps there were still some issues with what happened back then. I will try to investigate."

"Minerva, you should take Harry and Ron back. The kids should be getting to bed soon."

"Goodbye, Principal Dumbledore."

As Lin Yue finished her analysis, Dumbledore and Professor McGonagall showed no intention of saying more. Harry and Ron stood up, said goodbyes to Principal Dumbledore, and left the office.

"Come on, I'll take you back."

Principal Dumbledore smiled, stood up, and led Lin Yue and the five others out of the principal's office.

As they walked towards the Ravenclaw common room, Lin Yue felt a gaze on her from above, and when she looked up, it was Dumbledore's soft, loving blue eyes.

It seemed as if he was looking through her, as if gazing into the past or the future.

"Principal Dumbledore?"

Lin Yue tilted her head and called out to him softly.

"Oh," Dumbledore came back to his senses, shaking his head with a smile, "I'm getting old; it's easy to lose focus."

He looked at Lin Yue thoughtfully and said, "Miss Lin Yue, you've been quite active lately, and not just a little. Those pure-blood families are writing to me almost every day."

"Have I caused you trouble? I'm sorry, Principal Dumbledore."

Lin Yue said mechanically, lowering her head deeply.

"No, no, no, don't think like that, my child," Dumbledore shook his head, signaling Lin Yue to lift her head. "Young people shouldn't always keep their heads down and hunch over; you should walk forward with your chest out and head held high."

"As for those pure-blood families," a glint of mischief flashed in Dumbledore's eyes, "just ignore them. I'm getting old, my energy isn't what it used to be, and I can't read every letter."

"Pfft, haha..."

The other four girls present couldn't help but laugh out loud, aside from Lin Yue.

"To be honest, I should thank you, Miss Lin Yue." Dumbledore looked down at Lin Yue walking beside him with a kind expression, as if he were looking at his own granddaughter.

"Thank me?" Lin Yue raised her head, a hint of confusion flashing in her dazed eyes.

"Yes, thank you for using such gentle means to bring about a change."

Lin Yue fell silent for a moment and slowly said, "Directly resorting to killing as a means of intimidation is indeed the fastest and most efficient way, but Hermione... and everyone else, wouldn't like this method."

The kind smile on Professor Dumbledore's face widened a bit more as he shifted his gaze to Hermione and the other three girls.

"I think I really should take off my hat to salute you," he said, and surprisingly, he actually removed his wizard hat.

The four girls were startled and immediately stopped in their tracks, looking flustered at Professor Dumbledore.

"Professor Dumbledore, you don't have to do that..."

"Yeah, we didn't do anything, why are you...?"

Hearing the four girls' hurried inquiries, Professor Dumbledore shook his head while holding his wizard hat.

"You still don't understand what a great thing you have done."

"But you will understand in the future, when you grow up a bit more."

When they grow up a bit more, they will realize how precious it is that Lin Yue, who has not instigated violent change in the magical world, has them as her bonds.

And how great it is that they unknowingly accomplished this feat.

But for now, the four girls just exchanged glances, and even the oldest, Penelope, did not understand what Professor Dumbledore meant.

Great? They were just caring for and protecting their friend; how could that be called greatness?

As they resumed walking down the path, Professor Dumbledore put his wizard hat back on and looked down at Lin Yue with a friendly inquiry.

"Lin Yue, after you graduate, I wonder if you would be interested in staying at Hogwarts to teach?"

"After all, according to your plan, Hogwarts, the only magical school in Britain, should be very important to you."

Dumbledore's words were almost equivalent to a clear indication, and Lin Yue naturally understood his meaning.

Hermione and the others also understood, turning back with bright eyes to look at Lin Yue.

This was quite exciting, wasn't it? Dumbledore's implication was that Lin Yue could teach at Hogwarts after graduation and then become the headmaster of Hogwarts, right?

This way, she could grasp both the business and education aspects of the magical world, and with Hermione entering the Ministry of Magic after graduation, she would essentially have a firm hold on all aspects of the British magical community.

"I understand your meaning, Headmaster Dumbledore. I do not rule out the possibility of staying on to teach."

"However, I will rule out the possibility of being the headmaster of Hogwarts, at least until I have completely redistributed the business of the magical world. I will exclude that possibility for myself."

"Oh? Why?"

Principal Dumbledore looked at Lin Yue with great interest, curious about why she would refuse this point. Wouldn't it be easier to completely carry out the transformation and have everything in hand?

"The transformation I want to achieve is to prevent resources from being absolutely controlled by a few people, to avoid the emergence of a situation where a single lie can obscure everything."

"If I were to gain control over the British wizarding world's business and then take over Hogwarts, I would be equivalent to becoming the very kind of person I want to avoid, becoming the kind of person, I am trying to resolve now."

"I won't do such a thing." Lin Yue shook her head without a hint of change in her expression.

Hermione looked at her with admiration, her affection clearly deepening.

Hmm, this is the person she likes, the Lin Yue she admires, who can remain steadfast even in the face of temptation. She is solely focused on her goals, dedicated to becoming the person she wants to be.

The three senior sisters couldn't help but smile after hearing this; indeed, this is the Lin Yue they cherish, their best friend. This is the Lin Yue, the treasure of all Ravenclaw, the one everyone in Ravenclaw follows.

Principal Dumbledore nodded, said nothing more, and turned his gaze back to the entrance of the Ravenclaw common room, which was now in sight. His heart was filled with mixed emotions; this was a temptation that many could not resist. So how many people... could not compare to this still young child, Lin Yue?
