Voldemort also noticed Harry, but it was too late; Dumbledore should be returning soon. With an unwilling shriek, Voldemort dashed out of Hogwarts at the fastest speed.

Meanwhile, Principal Dumbledore hurriedly entered the Potions room through a large hole in the wall. Seeing Harry standing there unharmed, he let out a slight sigh of relief, but he didn't completely relax; after all, the hole in this wall and the one on the opposite side were not something Harry and the others could have done.

The only person he could think of who might have had close contact with Harry and could have done this was one person, and he still couldn't be sure if that child was safe.

"Principal Dumbledore!" Harry saw him relax completely and lean against the wall behind him. Now that Dumbledore was here, everything was over...

Before either of them could mention Lin Yue, she emerged first from the hole in the wall behind Harry. The little witch's robe was now in disarray, enough to show the dangers she had faced while dodging spells, and the dust covering it told the story of the fierce battle.

"Miss Lin Yue." Dumbledore felt a complete sense of relief when he saw Lin Yue come out safely. He waved his wand at her, helping to tidy her wizarding robe while carefully checking her physical condition.

"Good evening, Principal Dumbledore." Lin Yue looked at him expressionlessly, nodding politely to greet him.

"Principal Dumbledore, is Lin Yue okay?" Harry asked with concern from the side.

Putting away his wand, Dumbledore smiled kindly at Harry, "Don't worry, Miss Lin Yue is fine; she might just be a bit too tired. She should go to the hospital wing and ask Madam Pomfrey for some Dreamless Sleep Potion to rest."

"That's good to hear." Harry let out a breath.

Lin Yue stood quietly beside Harry, her expression calm and her face devoid of emotion, as if the conversation between Harry and Professor Dumbledore had nothing to do with her, but rather with someone completely unrelated.

As they walked out of the Forbidden Zone with the two children, Professor Dumbledore turned to Harry and said, "You are very brave, Harry, just like your parents. They would be proud of you."

"Yeah." Harry smiled, but inside he reminded himself not to be so reckless in the future.

Tonight, Ron had been knocked out on the chessboard, and Lin Yue, covered in dust, made him feel uneasy. He couldn't bear to think about what would happen if he caused harm to his friends because of his actions; he would never be able to forgive himself.

Looking at Lin Yue, who seemed to maintain her calm demeanor beside Harry, Professor Dumbledore paused for a moment before he reached out and gently patted her head, like a kind grandfather comforting his granddaughter.

"Miss Lin Yue, your loyalty to your friends and your bravery in the face of danger are commendable. Please allow me to apologize to you, even though you may not know why."

Listening to Professor Dumbledore's words, Lin Yue looked up at him calmly. She truly couldn't figure out why he was apologizing to her. Teachers and parents do not make mistakes; all she needed to do was obey them.

Under Professor Dumbledore's gentle gaze, Lin Yue slowly withdrew her gaze, running calculations in her mind.

Breaking school rules by going out at night, one punishment; knocking out the three-headed dog and injuring Hagrid's pet, one punishment; using the Fire-Making Spell to damage the Devil's Snare, which harmed Professor Sprout's personal property, one punishment; blowing up a door and damaging school property, one punishment; destroying pieces on the chessboard and damaging Professor McGonagall's personal property, one punishment; tearing down two walls, two punishments; damaging a floor, one punishment.

Quickly completing her calculations, Lin Yue concluded that she needed to punish herself eight times.

"Professor Dumbledore, how are Hermione and Ron?" As they ascended the moving staircase, Harry asked Dumbledore, who was ahead of him.

"Minerva has already taken them to the hospital wing; they are fine," Dumbledore replied, turning back to Harry with a reassuring smile.

Upon hearing Hermione's name, Lin Yue, who had just finished calculating her punishments and had memorized them, instinctively looked up at Dumbledore. After hearing him say that Hermione was fine, she lowered her head again and continued walking.

If you spot this tale on Amazon, know that it has been stolen. Report the violation.

They arrived at the hospital wing without any issues. Ron's injuries had been treated by Madam Pomfrey, but he was forced to drink a Dreamless Sleep Potion and had fallen asleep.

Hermione, worried about Lin Yue and Harry, refused to take the Dreamless Sleep Potion. She wanted to see Lin Yue and the others were safe as soon as possible. Since she wasn't injured, Madam Pomfrey and Professor McGonagall let her be.

Now, seeing Lin Yue and Harry follow Professor Dumbledore into the hospital wing, she jumped off the bed without hesitation and ran up to Lin Yue, hugging her tightly.

Lin Yue, suddenly embraced by Hermione, was taken aback for a moment, then, mimicking her earlier actions, raised her arms to return the hug.

"Merlin above... I'm so glad you're okay..." Hermione's voice was choked with emotion, and she felt a wave of fear in her heart.

Lin Yue opened her mouth; her brain told her she wanted to say something, so she mechanically uttered a sentence. "Um... I'm fine, Professor Dumbledore checked on me."

Hermione released Lin Yue and nodded at Professor Dumbledore, "Thank you, Professor Dumbledore."

Professor Dumbledore shook his head, looking at the two girls with deep guilt in his eyes. "No... I should be the one apologizing to you."

He spoke the last part almost in a whisper. The school should be a place that protects students, but for Harry's future and the future of the wizarding world... he had to harden his heart and let Harry and his friends gradually accept training.

Even if Harry and the others would hate him in the future, even if people would say he wasn't a qualified headmaster, it didn't matter; at least they could still stand safely in Hogwarts at that time.

But... could he really harden his heart? Looking at the two young witches standing in front of him and Harry, who was trying to cover his eyes nearby, Professor Dumbledore couldn't help but ask himself this question.

"Alright, I think Miss Granger, you should take the Dreamless Sleep Potion and get some good rest."

Professor McGonagall walked over from Ron's bedside, looking at the three children, her lips trembling. She had just finished listening to Hermione explain everything. Voldemort... she had come so close, so close to never seeing these children again. If she had believed them back then... Professor McGonagall took a deep breath, suppressing the moisture in her eyes, and removed her wizard hat in front of the three students.

"I’m sorry, Mr. Potter, Miss Granger, Miss Lin. I didn’t believe you at the time, and it caused you to go alone... to face danger."

Hermione was the first to feel uneasy, raising her hand in a somewhat flustered manner, "No, it’s not your fault, Professor."

Harry also raised his hand, feeling a bit embarrassed as he scratched his cheek, "Hermione is right, it’s not your fault, Professor. I was too anxious at the time and spoke in a way that made you misunderstand."

Looking up with a blank expression at Professor McGonagall, Lin Yue stated her understanding, "The professor wouldn’t be wrong."

Everyone present thought she was comforting Professor McGonagall, so they didn’t notice the specific words she used: "wouldn’t be wrong."

Under Madam Pomfrey's arrangement, Lin Yue, Hermione, and Harry each lay down on a hospital bed and took the Dreamless Sleep Potion. Without any hesitation, Lin Yue drank it all in one go. Her face remained unchanged, but two seconds later, her eyelids began to feel heavy, and the next moment, she completely closed her eyes and fell into a deep sleep.

Seeing the children starting to rest, the two professors present showed relieved smiles. Such things shouldn’t happen.

"Then why is this child’s spirit so tense? She should have had a good sleep for a long time," Madam Pomfrey asked, leaving Headmaster Dumbledore momentarily speechless. Although he was the headmaster, he didn’t know everything.

It was Professor McGonagall, sitting next to him, who pursed her lips and answered her question. "At the beginning of the school year... I, Flitwick, and Sprout all left her advanced study books, but later we found that all subjects were assigning her work, and since she was already learning enough, we stopped."

Madam Pomfrey nodded, then shook her head, "No, she hasn’t been resting well lately; otherwise, her condition wouldn’t be this bad."

"Maybe she’s been studying on her own," Professor McGonagall speculated, "after all, she is a Ravenclaw."

"Alright..." Madam Pomfrey sighed, reluctantly accepting this explanation.

It just so happened that it was time for final exams, and Lin Yue hadn’t attended Potions class recently, nor had anything happened to make her punish herself, so the dark bruises on her left thigh had faded. Moreover, this time when she went to the restricted area on the fourth floor for convenience, Lin Yue didn’t punish herself in advance; otherwise, Madam Pomfrey would have noticed.

Even so, Madam Pomfrey had prepared enough Dreamless Sleep Potion for her to last several days, intending to let her sleep well in the hospital wing before going back. This way, the child wouldn’t just focus on studying and neglect resting after returning.

Lin Yue is ultimately a student of Ravenclaw, so Principal Dumbledore still notified Professor Flitwick. Before long, Professor Flitwick pushed open the door to the infirmary and rushed in, even his pajamas were not changed, which showed how urgent his arrival was.

"Dumbledore, how are the children?" Professor Flitwick asked in a low voice upon seeing the four children sleeping soundly in their beds.

"Nothing serious, they're all resting," Principal Dumbledore shook his head.

"Yes, but Miss Lin Yue's condition isn't too good," Madam Pomfrey said, using her wand to direct several bottles of potions to Lin Yue's bedside.

"What happened to Miss Lin Yue?" Hearing Madam Pomfrey's words, Professor Flitwick immediately became anxious.

"She needs rest, plenty of rest," Madam Pomfrey said firmly, "And her stomach—Merlin's dinner, I can hardly believe how she managed to get her stomach into this state. She already shows signs of a stomach ailment. By the way, was she the student who only took a few minutes to eat before?"

"Yes... Albus and Minerva advised her too, but they only managed to get her to eat a bit slower on Christmas Day," Professor Flitwick sighed, his voice low.

Madam Pomfrey took a deep breath, "Very well, it seems I need to keep some stomach-strengthening potions on hand from now on!"

Before they could say another word, as the hour passed, Lin Yue's eyelids struggled to open. Her subconscious was battling against the effects of the potion.

With her mind in a haze, she managed to crack her eyes open a slit, but ultimately, she was forced to shut down again before she could fully open her eyes, slipping back into a deep sleep.

The three professors and Madam Pomfrey naturally did not miss this scene. Madam Pomfrey furrowed her brows and stepped forward to take a look; she had never seen someone wake up from the Dreamless Sleep Potion before the time was up.

After a careful examination, she found that the potion still had its effects, so what was going on?

Madam Pomfrey looked at the most knowledgeable person present, Professor Dumbledore, but he shook his head, indicating that he was also unsure.

After thinking for a while, Madam Pomfrey simply moved a chair and sat down next to Lin Yue, keeping a close watch on her condition.

Professor Flitwick, as the head of Ravenclaw, also did not want to leave and took a chair to sit beside his student.

Seeing this, Professor McGonagall transformed into a cat and jumped onto the foot of Lin Yue's bed, while Professor Dumbledore left to deal with the situation regarding Quirrell.

So that night, the two professors along with Madam Pomfrey watched as Lin Yue forced herself to wake up every hour, only to fall back into a deep sleep. The Dreamless Sleep Potion was effective for eight hours, and she went through this cycle eight times.

The three of them felt uncomfortable just watching; the sight of her struggling and waking up with all her might...
