After hearing Lin Yue's explanation, Harry stood in place for a long time without speaking. Hermione and Lin Yue remained in an embrace until Harry closed his eyes and spoke again, prompting the two of them to let go.

"I'll go to the forbidden corridor on the third floor tonight and get the Philosopher's Stone before Professor Quirrell does."

"No! Harry, that's very dangerous!" Hermione exclaimed, her eyes wide as she looked at Harry, clearly disapproving of his plan.

"We can go tell the professors, tell Professor Dumbledore. They will handle this, instead of us first-year students taking risks."

Harry thought for a moment and realized that Hermione was right, so he nodded in agreement.

"Okay, I agree. Let's go tell the professors and see what they say."

The four of them immediately stopped hesitating and quickly ran across the grass towards Hogwarts Castle. Lin Yue, being pulled along by Hermione, was at the back, her mind rapidly organizing and analyzing the known information.

Her meticulous brain quickly connected to all the events that had happened this semester: the duel challenge with Malfoy, the frantic run into the forbidden corridor on the third floor, and the discovery of the three-headed dog and what it was guarding.

Harry had received an invisibility cloak from an unknown sender on Christmas, and shortly after, he coincidentally found the Mirror of Erised. Hagrid had revealed top-secret information to them, such as about Nicolas Flamel and the three-headed dog, Fluffy.

One by one, although there was too little information and evidence for Lin Yue to analyze and deduce the truth, she had a vague thought in her mind: these events were not coincidences; there must be someone behind them.

Someone was pushing Harry, or rather, pushing them to do something. Coincidences can happen once or twice, but if they happen every time, then someone is orchestrating these coincidences.

Even though she thought of this, no one asked her, so Lin Yue remained silent, expressionless, as Hermione pulled her into Hogwarts Castle, where they happened to run into Professor McGonagall.

Professor McGonagall saw the Gryffindor trio pulling Lin Yue into the castle and smiled gently, "Mr. Potter, Mr. Weasley, Miss Granger, Miss Lin Yue, why aren't you taking a break after your exams? The sunshine today is quite nice."

"Sorry, Professor McGonagall, we have an urgent matter. Where is Professor Dumbledore?" Harry asked anxiously.

Seeing Harry's expression, Professor McGonagall was clearly taken aback. "Professor Dumbledore has gone to a meeting at the Ministry of Magic."

"At a time like this?!" Harry found it hard to accept. The Philosopher's Stone was likely about to be taken by Voldemort, and Dumbledore, the only person Voldemort feared, was at a meeting?

"Professor Dumbledore is very busy; he has many matters to attend to," Professor McGonagall frowned. "Mr. Potter, what exactly is the matter?"

Harry blurted out without thinking, "It's a secret."

Hermione took a deep breath, and Ron couldn't help but cover his face with his hand; Harry had definitely said the wrong thing!

Only Lin Yue, who showed no emotion, thought that Harry had spoken the truth; the matter of the Philosopher's Stone was indeed a secret, wasn't it? A top-secret one at that.

Professor McGonagall's nostrils flared slightly as she listened to Harry. "Alright, Mr. Potter, since that's the case, you can wait until tomorrow when Professor Dumbledore returns and then go to his office."

Harry's heart raced, and he spoke urgently, "Tomorrow might be too late. Alright, it's about the Philosopher's Stone; someone is trying to steal it!"

With a clatter, all the books Professor McGonagall was holding fell to the ground. She quickly reacted, bent down to pick up her books, and then looked at the four children with a serious expression.

"I don't know how you found out about the Philosopher's Stone, but it is well protected, so you don't need to worry."

"Alright," seeing that Harry wanted to say something else, Professor McGonagall shook her head, "You all should go and relax."

With that, Professor McGonagall strode away, nodding at Hermione as if to signal her to take good care of Lin Yue and rest. Seeing Professor McGonagall nod at her, Hermione felt a bit guilty and averted her gaze. She knew very well that they couldn't seek the professor's help... they would probably have to handle it themselves. Sure enough, Harry turned to his three friends and said one sentence.

Stolen novel; please report.

"You all go rest; I’ll go prepare. Tonight, I will go through the trapdoor and get the Philosopher's Stone."

Immediately, he saw Hermione looking at him as if he were crazy, and Ron staring at him as if he were joking. Even Lin Yue was staring at him blankly, "Based on personal analysis, the likelihood of them agreeing to let you go alone is almost zero."

Lin Yue spoke up in Harry's line of sight, and Hermione and Ron instinctively nodded along.

Hermione slightly raised her chin, "Actually, it's quite normal for the professor not to believe it. After all, it's really absurd for a student to suddenly say that the Philosopher's Stone is going to be stolen."

"So I was also prepared just now to go with you to get the Philosopher's Stone tonight."

"Exactly," Ron chimed in from the side, "You didn't think we would agree to let you go on this adventure alone, did you?"

"Wait, you guys don't have to..." Harry waved his hands anxiously. Didn't they understand? They might have to face Voldemort this time, and they could die!

"It doesn't matter," Ron stepped forward and put his arm around Harry's shoulder, "Anyway, if Voldemort really comes back, no one will have a good time."

"My family is closely related to Muggles, and Hermione is a Muggle-born. Rather than waiting for him to get the Philosopher's Stone and resurrect, we might as well take the initiative."

Hermione linked her arm with Lin Yue's and followed behind the two, "That's right, and if the three of us go together, our chances of success will definitely be greater."

She had subconsciously excluded Lin Yue from this plan. It was one thing not to take Lin Yue along for a relaxing outing, but this was a life-threatening activity... she absolutely did not want to involve Lin Yue. Clearly, Harry and Ron shared the same thought, so they didn't discuss the plan to get the Philosopher's Stone in front of Lin Yue any further.

If sacrifices were to be made, sacrificing the three of them would be enough; there was no need to involve another person. Lin Yue was brought to the entrance of the Ravenclaw common room by Hermione, without any emotional fluctuations. Hermione reached out to straighten Lin Yue's collar and then looked up into her eyes.

"Take a good rest; we'll be leaving now."

After Hermione finished speaking, she turned and left. She had a feeling that she couldn't stay any longer; if she did, she might not want to leave at all.

Lin Yue watched intently as Hermione and the others left, clearly knowing that they were going to prepare for their trip to the forbidden area on the Third floor to retrieve the Philosopher's Stone. At the same time, she understood that the reason Hermione and the others sent her back was that they didn't want her to be involved.

However, lacking emotions, she didn't understand—or rather, she couldn't grasp what it felt like to worry, so she couldn't figure out why Hermione and the others didn't want to take her along. Clearly, if they brought her, their safety and chances of survival would be higher.

Mechanically lowering her head, Lin Yue turned to answer the question posed by the bronze door knocker and walked into the Ravenclaw common room.

Back in the dormitory, sitting in her seat, Lin Yue instinctively wanted to take out a book and continue studying. However, the reality was that she couldn't recall any knowledge points in her mind. Her brain was in chaos, and her heart felt as if it had been tightly gripped by someone; she couldn't think at all and could only sit there in a daze.

What was wrong with her... what was this situation? Why was her heart tightening in waves? Why was her brain screaming and trembling?

She had never experienced this before... wait, she had. When was that?

It seemed like a long, long time ago, so far back that her memory was hazy. It seemed to be when she was just a few years old, seeing two fully armed men drag away a sister she knew from next door.

She felt just like she did now. But why was that? She felt... very, very what?

Lin Yue's brain kept stuttering, like a computer trying to start something but failing repeatedly. She sat there for several hours, remaining in her chair until Cho Chang and Marietta finished dinner and played with their friends for a while until curfew. Seeing Lin Yue sitting there in a daze, Cho Chang and Marietta were momentarily stunned.

Cho Chang furrowed her brows and walked slowly forward, bending down to take a look. To her surprise, she noticed that Lin Yue's eternally expressionless face had actually faintly wrinkled into a slight frown.

This discovery made Cho Chang's heart skip a beat. Lin Yue frowned?! What could have happened that was so serious!

"Lin Yue, Lin Yue, what's wrong with you?"

The slightly furrowed brows of Lin Yue instantly relaxed, and she returned to her usual expressionless state. Turning to look at Cho Chang, she spoke in a flat tone, posing a question.

"I thought of a few people and what they are going to do. My mind is in chaos, and my heart is racing. Why is that?"

Cho Chang was momentarily at a loss for words due to Lin Yue's question, but Marietta, who was behind her, gently spoke up.

"If you are talking about one person, I might say you like her. But since you mentioned several people, it could mean... you know they are going to do something dangerous, and you are worried about them."

"Worried..." Lin Yue raised her hand to gently touch her chest, where her heart was racing uncontrollably. "So this feeling is what worry really is," rather than just a term defined in books.

"Lin Yue, is something wrong?" Cho Chang squatted down, gently holding Lin Yue's hand and looking at her with concern.

Lin Yue turned her head, her gaze calm as she looked at Cho Chang. In her mind, the image of her revealing the truth and Cho Chang and Marietta following her to the restricted area on the third floor suddenly flashed.

Her heart tightened again inexplicably. Worry, this is worry...

"This is a secret," Lin Yue spoke truthfully, while also avoiding the possibility of Cho Chang and Marietta accompanying her.

Yes, going to the restricted area on the third floor, just now, she understood what worry was, and her mind immediately made this decision.

Suddenly, standing up, Lin Yue strode towards the door. "Wait..." Cho Chang called out to stop Lin Yue.

Lin Yue turned around and looked at her with a blank expression. Cho Chang tried to suppress her worries and smiled gently.

"You haven't had dinner yet, have you?"

"No," Lin Yue shook her head.

"Let's go get it for you. By the time you come back... you can eat." So you must come back!

"Okay, thank you, senior." Lin Yue nodded, turned around, and walked out the door with big strides.

Marietta walked over to Cho Chang's side, looking at the dormitory door with concern. "Are we really just letting her go alone?"

"With the two of us... we would probably just complicate things if we went," Cho Chang shook her head. "Let's go out again; at least we can't let her come back hungry."

Marietta nodded, sighed, and followed Cho Chang out, heading straight for the Hogwarts kitchen, hoping Lin Yue could return quickly and safely so that she might still get to eat some warm food.

Arriving at the restricted area on the third floor, Lin Yue thought about her night adventure and the need to break into the restricted area, so she reached for her left thigh but then remembered what she had to do later.

Lin Yue withdrew her hand; she needed to be able to move quickly, she thought emotionlessly, so she would wait until everything was over before accepting her punishment.

Looking at the wooden door blocking her way, Lin Yue raised her wand and used a unlocking spell, causing the door to swing open instantly.

As she stepped through the door, the three heads of the three-headed dog immediately turned towards her.

Before the three-headed dog could start barking, Lin Yue tightened her grip on her wand and calmly shouted at it, "Sleep!"

Bang! The powerful spell sent the three-headed dog, Fluffy, flying, crashing heavily onto the ground behind it.

However, this did not cause much harm to the tough-skinned three-headed dog; it was merely forced into a deep sleep.

Pulling open the trapdoor on the ground, Lin Yue jumped down without hesitation.

After a while of falling, Lin Yue landed steadily on the bottom of the Devil's Snare, immediately recognizing it. With a blank expression, she waved her wand.

" Incendio!"

A fierce flame immediately began to burn beneath the Devil's Snare, causing it to retract its tendrils in a frenzy. Lin Yue fell down but her mind remained calm, adjusting her posture in mid-air and landing smoothly on the ground.

Waving her wand again, the flames ceased, and she looked up at the Devil's Snare. Even though she consciously weakened the spell's power, the Devil's Snare still suffered some damage.

The three-headed dog belonged to Hagrid, and the Devil's Snare belonged to Professor Sprout.

Both were personal property, and although she had no choice but to cause damage, it was still a violation of the rules and destruction of their personal belongings.

These were two points that would require punishment, which Lin Yue firmly remembered in her mind, and then she walked forward without any emotional fluctuations.

Opening the door to the next room, Lin Yue looked up and saw a swarm of keys flying around the ceiling. Looking at the door across the room and the keyhole on it, she immediately understood what this room wanted her to do.
