Listening to Professor Dumbledore's words, Lin Yue's mind began to rapidly integrate information and make inferences.

"Based on the information available, while the Basilisk is extremely dangerous and is a magical creature, it still belongs to the Serpentes family and has the body structure of a snake."

Professor Dumbledore nodded, looking at Lin Yue, waiting for her further analysis.

Hermione and the others stared at Lin Yue with wide eyes; the Basilisk is a dangerous magical creature, and just making eye contact with it could be fatal.

They were also curious about how the Basilisk moves.

"The Basilisk has the body structure of a snake, and the most suitable places for snakes to navigate through in a building, which also remains undetected by humans, are the pipes."

"Therefore, it is highly likely that the Basilisk moves through the pipes of Hogwarts."

Lin Yue quickly compared the body structure of snakes with various architectural floor plans. Since she did not have the floor plan of Hogwarts, she could only use the architectural plans she was familiar with as a substitute.

The conclusion she reached was that moving through the pipes is the most compatible with the Basilisk's body structure and the best way for it to hide.

"The pipes..." Professor Dumbledore murmured, nodding his head. "Thank you very much for your conclusion, Miss Lin Yue. We will conduct an investigation as soon as possible."

The basilisk is indeed too dangerous. After realizing that the monster in the chamber might be a basilisk, all the professors at Hogwarts were already prepared to enter the chamber to eliminate it. Lin Yue nodded with a calm expression, but her mind was instinctively continuing to deduce.

It is known that the last basilisk attack occurred fifty years ago, and during that incident, a student lost their life. According to one of the books in the library that roughly describes the ghosts of Hogwarts, Moaning Myrtle died fifty years ago in the second-floor girls' bathroom.

Therefore, Moaning Myrtle should be the victim of the basilisk attack fifty years ago, and the location of her death was indeed the second-floor girls' bathroom. Furthermore, considering that this current basilisk attack is happening outside the second-floor girls' bathroom, the place where the basilisk can enter and exit, which is the entrance to the Slytherin chamber, should be in the second-floor girls' bathroom.

Lin Yue easily deduced the entrance to the chamber of secret as her thoughts flowed. However, Principal Dumbledore did not press further; he smiled and stroked his beard at the five little witches.

"Thank you for coming all this way to listen to an old man's words."

"It's getting late, so you should all return to your common rooms. There's a Quidditch match tomorrow morning, and I imagine you wouldn't want to miss it."

As he spoke, he winked at Lin Yue. "Miss Lin Yue, remember to go watch the match tomorrow. It's the weekend, so take a good rest."

Although thoughts of not being able to relax still popped up in her mind, the world had changed, and she should follow the instructions of this time professor.

Lin Yue expressionlessly made her judgment, then instinctively nodded, her voice as calm as a still pond.

"Okay, I will go. Thank you, Principal Dumbledore."

"You're welcome. You all can go back now."

Principal Dumbledore waved his hand, signaling Lin Yue and the others that they could leave.

The five little witches turned and walked towards the door of the principal's office. Halfway there, Principal Dumbledore suddenly seemed to remember something and said, "Oh, by the way, I wonder if Miss Cho Chang and Miss Marietta would mind having an additional roommate in your dormitory?"

Dumbledore's unexpected question caught Cho Chang and Marietta off guard, and they turned to look at him in confusion. Following his gaze, they saw... Hermione, who was standing next to Lin Yue, holding her hand.

Their eyebrows jumped in surprise, and Cho Chang and Marietta smiled and shook their heads. "We don't mind, Principal Dumbledore."

"We have no objections, Principal Dumbledore. After all, the Ravenclaw dormitory was originally planned as a four-person room, wasn't it?"

The two spoke one after the other, and after expressing their stance, Cho Chang looked at Principal Dumbledore with a hint of uncertainty.

"However, Principal Dumbledore, you mean to add another bed in our dormitory, right?"

Cho Chang squinted slightly as she spoke, and it was clear that Hermione and Lin Yue still hadn't figured things out. Lin Yue was like an emotional center that was just born, and she was even being suppressed. Even Hermione, due to her young age, temporarily didn't have any thoughts in that regard.

Occasionally, they would sleep together in special circumstances, but if they were to sleep together all the time... they were still a bit too young for that.

The story has been illicitly taken; should you find it on Amazon, report the infringement.

Dumbledore felt a bit of sweat on his back as he caught the gaze of Cho Chang and Marietta. Unable to help but chuckle and shake his head, he gently replied, "Of course, Miss Cho Chang, Miss Marietta."

These two kids truly regarded themselves as Lin Yue's older sisters; they were both good kids.

"Then we have no problem at all," Cho Chang said with a satisfied smile, and Marietta beside her nodded with a smile as well.

Hermione, who was holding Lin Yue's hand behind them, clearly didn't realize that Dumbledore's mention of the two older students not minding an extra person in the dormitory referred to her. She cautiously leaned closer to Lin Yue's ear and quietly asked if there was someone who would be staying in their dormitory, wondering if it was a new student.

Lin Yue mechanically turned her head to look at Hermione and shook her head, "The freshmen already have their own dormitories."

Penelope, who was listening to their conversation, couldn't help but twitch her mouth.

The two younger students still hadn't figured things out, and the professors were already paving the way for them... Sigh, Lin Yue is clearly still so young.

Reaching out to gently rub Lin Yue's little head, Penelope looked at Hermione with a warm expression.

"Principal Dumbledore was referring to you when he mentioned whether Cho Chang and Marietta would mind having an extra roommate."

"Referring to me?" Hermione pointed at herself in a daze, her face instantly turning red.

"Oh, um... what I mean is, why?"

Hermione was a bit incoherent; to be honest, she didn't even know why she felt so shy.

"Maybe it's because," Penelope looked at the bashful Hermione and the "naive and ignorant" Lin Yue, and struggled to explain, "you really care about Lin Yue; you're her best friend, right?"

Lin Yue is still young, so there's no rush. Let's make Hermione work a little harder for now, and also let her recognize her feelings for Lin Yue. Penelope thought to herself, and she had to admit that she was slightly biased towards Lin Yue over Hermione, just a little bit.

"Okay, fine." Hermione blushed and lowered her head.

Feeling Cho Chang and Marietta approaching, she quietly muttered a thank you.

The two senior sisters lovingly reached out to ruffle Hermione's little head, "You're welcome. It's a good thing that you can spend more time with Lin Yue."

"Yeah, and if there are two junior sisters in the dorm, it will definitely be very interesting and lively."

"Mm!" Hermione's shyness was somewhat chased away, and she lifted her head to reveal a big, bright smile.

Lin Yue stood by, watching the kind-faced Cho Chang, Marietta, and Penelope as they looked at Hermione. For some reason, her brain told her that, based on facial expression analysis, the way the three older students looked at Hermione didn't seem like the typical expression of seniors looking at a junior.

Reaching this conclusion, Lin Yue felt no sense of doubt. After confirming that Professor Dumbledore had no further words to say, she politely bid farewell to him and followed Hermione and the others out of the headmaster's office.

As they exited the office and came out from behind the stone beast, Penelope turned to Hermione beside Lin Yue and asked, "Hermione, are you going back to Gryffindor or are you coming with us to stay in Ravenclaw?"

Since Professor Dumbledore had just made it clear that Hermione could stay in their dormitory, she could go there openly.

The thought of staying in Ravenclaw together made Hermione's heart flutter. Staying in Ravenclaw together meant sharing a room with Lin Yue, and she was truly tempted. But then she thought of her two good friends, Harry and Ron, who were still waiting for her to help them with their homework...

Hermione ground her teeth; it seemed she wouldn't be able to live with Ravenclaw and Lin Yue after all.

"Not today," Hermione sighed and shook her head. "I still need to go back and supervise Harry and Ron's homework."

"Otherwise, who knows what their assignments will end up looking like."

Penelope couldn't help but laugh a little, and Cho Chang and Marietta also covered their mouths and snickered.

Well, it's understandable for the boys in Gryffindor.

They're a bit livelier; you can't say they're particularly bad at studying, but you also can't say they're exceptionally good or self-disciplined.

"Alright then, we'll head back to Ravenclaw first," Penelope waved at Hermione.

"Goodnight, Hermione."

Cho Chang and Marietta also waved goodbye to their juniors, while Lin Yue stepped forward without any change in expression.

"I'll walk you back."

"Huh?" Hermione was taken aback, looking at Lin Yue in confusion.

"The Basilisk is in Hogwarts. According to legend, the things left behind by Slytherin will eliminate those he deems unworthy of learning magic, which means Muggle-born wizards."

"You are at a certain risk, so I'll walk you back."

Lin Yue's voice was devoid of emotion, and her speech was very formal. However, Hermione felt a warmth in her heart as she listened, but she still raised her hand to pinch Lin Yue's cheek. "No need, I can go back by myself. Otherwise, I’ll worry about you going back to Ravenclaw alone."

Lin Yue shook her head calmly. "I'll take you."

Hermione wanted to say something else, but Marietta directly interrupted her, cheerfully pushing Lin Yue into her arms. "Let Lin Yue take you; otherwise, it might not be very safe for you to go back alone."

"We can go back with you; we can drop you off at Gryffindor first, and then we’ll head back to Ravenclaw."

Lin Yue turned her head from Hermione's embrace and looked at the three senior sisters, who were all in agreement with the proposal, and flatly rejected it. "The route back for you is shorter and safer, and if we encounter a Basilisk, my chances of survival alone are higher."

The three senior sisters exchanged glances. Well, they had to admit that if they really encountered a Basilisk, they wouldn't be able to do much other than hold Lin Yue back. Of course, they could help Lin Yue "take the hit," but knowing Lin Yue's usual style, she wouldn’t let them do that. In the end, she might even have to help them "take the hit."

"Alright, then it's settled. We'll head back to the dormitory first, and then Lin Yue will take Hermione back."

Penelope clapped her hands to make a decision, looking at Hermione, "When Lin Yue returns to Ravenclaw, we can have her use the fireplace to let you know she's safe, how does that sound?"

Hermione bit her lip and glanced at Lin Yue, whose face still showed no change and gave no indication of wanting to change her mind.

"Alright," Hermione nodded, allowing Lin Yue to escort her back to Gryffindor.

Lin Yue was led by Hermione as they walked back to Gryffindor, while Penelope and the others went straight back to Ravenclaw.

Nothing happened along the way.

The Hogwarts castle was quiet, with only the sound of their footsteps echoing softly around them.

After escorting Hermione to the entrance of the Gryffindor common room, Lin Yue looked down at the hand Hermione was holding.

Releasing her hand, Hermione hugged Lin Yue tightly, "Be careful on your way back."

"Okay," Lin Yue replied emotionlessly, instinctively returning the hug.

"Good night, try to have sweet dreams," Hermione couldn't help but nuzzle Lin Yue's cheek.

She really loved that soft, smooth feeling.

"Good night."

Lin Yue responded with a sound, but as for the latter half of the sentence, she wouldn't dream of it.

Releasing the arm she had wrapped around Lin Yue, Hermione watched her turn and walk away.

It wasn't until Lin Yue had turned a corner and disappeared from sight that Hermione let out a breath and turned to the portrait of the Fat Lady to say the password.

The Fat Lady's portrait slowly opened, and Hermione used her hand to "cool down" her slightly warm face.

Then, with a cold expression, she strode into the Gryffindor common room; she needed to check on Harry and Ron's homework.

She hoped they had done it seriously; otherwise... Hermione flicked her hair, her eyes sparkling with a Gryffindor-like cunning.

Walking quickly back to the Ravenclaw common room, Lin Yue maintained an expressionless face as she passed one corridor after another.

Under the "cover" of her footsteps, there was a faint sound of footsteps behind her.

Although Hogwarts Castle was indeed large enough to create echoes, her footsteps were not loud enough to produce an echo, and the echo wouldn't come from just one direction so precisely.

Someone was following her, and Lin Yue's mind quickly assessed the situation.

This person was stalking her, lowering their footsteps, using her own footsteps as cover; they didn't want her to discover them.

This person had ill intentions towards her, and after piecing together all the information, Lin Yue reached a conclusion.

Previously, Hermione had said that if something happened to her, she would worry, and many others, like Senior Cho Chang and Senior Marietta, would worry too.

Worrying could be very distressing, and with a quick judgment in her mind, Lin Yue swiftly turned into a nearby corridor.
