The final exams at Hogwarts weren't difficult, at least not for Lin Yue. The professors tested knowledge that had been covered in class, unlike her previous exams that included some extracurricular or advanced material. Therefore, Lin Yue found all her exams went very smoothly; every knowledge point and every answer was in her mind.

With a blank stare fixed on the paper, Lin Yue would think through each question five times, repeatedly confirming every word before writing it down, ensuring she wouldn't need to make any corrections after finishing. Corrections would lead to point deductions, and Lin Yue constantly reminded herself of this. In a previous exam, she had lost five points because there were signs of changes on one question, which resulted in a ten-minute punishment of standing in the snow—her first experience of her feet itching and hurting.

After neatly finishing the exam, Lin Yue stared at her paper, mentally going through it again and again until the bell for submission rang. Expressionless, she stood up, slung her backpack over her shoulder, and walked out of the exam room. This was her last exam, and also the last exam for all the students at Hogwarts. After this exam, all the students at Hogwarts would have completed their final exams for the year.

Students cheered as they rushed out of the exam room, heading towards the outside of Hogwarts Castle. They wanted to run wildly on the grass, bask in the sun, and go by the Black Lake to see the giant squid; they just didn’t want to stay in the castle any longer. After being "tormented" by final exams for two weeks, they needed to relax.

Amidst the cheers and excitement, Lin Yue, who walked silently against the crowd, appeared quite odd. She walked purposefully onto the moving staircase, quickly heading towards the Hogwarts library. The end-of-year exams were just one set of tests; there would be more exams ahead, so her studies couldn't stop, nor should they. She needed to continue learning.

As she made her way, students coming out of various exam rooms noticed Lin Yue and consciously made way for her. This well-known study fanatic from Ravenclaw, an unflagging monster of diligence, was undoubtedly heading to the library.

Upon entering the library, Lin Yue, under the watchful gaze and sighs of Madam Pince, dropped her backpack, grabbed a stack of books from the shelves she had been reading, returned to her seat, and entered a state of study, beginning to read quickly. Page after page of content was continuously absorbed by Lin Yue's mind, while Harry and Ron, having finished their exams, were being led to the library by Hermione.

"Hermione..." Harry swallowed hard as he looked in the direction the three of them were walking. "I don't think you're planning to go to the library to check if your answers are correct, right?"

Let him be, he just finished his final exams and wanted to relax his brain for a bit.

"Of course not," Hermione turned back to Harry, her face showing a look of 'what are you talking about?' "I'll do that in a couple of days."

"Merlin..." Ron raised his hand to cover his face in agony. Well, at least she wasn't planning to do that today, right?

"So what are we going to do?" Harry looked at Hermione in confusion, then suddenly realized.

"Are we going to the library to find Lin Yue?"

"Exactly," Hermione nodded and turned back to continue walking upstairs. "Even though the final exams are over, knowing her, she must still be studying in the library. Let's go find her and take her out to relax a bit."

"True," Ron nodded as he followed Hermione. "She really worked hard during the finals."

Thinking about Lin Yue's determination to memorize the textbook and spells, and the thick stack of parchment always stuffed in her backpack, Harry silently nodded in agreement with Ron's words.

The three of them arrived at the library, and unsurprisingly, they saw Lin Yue sitting at her usual spot, engrossed in her book.

Completely absorbed in her studies, Lin Yue didn't notice Hermione and the others' arrival at all. However, Madam Pince couldn't help but show a pleased expression upon seeing the three of them.

Hermione smiled and greeted Madam Pince before walking up to stand beside Lin Yue.

As usual, Hermione waited until Lin Yue finished a page before speaking.

"Lin Yue, good afternoon."

Hearing her full name, Lin Yue instantly snapped out of her studying state, turned to look at Hermione, and replied mechanically, "Good afternoon, Hermione. Is there something you need?"

Hermione smiled gently at Lin Yue, her voice so soft that it left the two boys behind her in disbelief.

"We just finished our final exams today, why don't we go out and relax a bit?"

Harry and Ron chimed in, "Yeah, yeah, let's go out and unwind."

"Exactly, give yourself half a day off; you've worked hard enough."

Lin Yue stared blankly at Hermione, a thought resurfacing deep in her mind—she wanted to agree with Hermione.

Nodding without any emotion, Lin Yue closed the book in her hands, stood up, and said, "Okay, let's go."

The narrative has been stolen; if detected on Amazon, report the infringement.

Hermione cheered happily, reaching out to help Lin Yue pack her book into her backpack. Before Lin Yue could even put it on her back, Ron had already taken it and slung it over his shoulder.

Ron shrugged under Hermione's gaze, "Hey, Harry and I are here too. Lin Yue's backpack is pretty heavy; we'll take turns carrying it."

Hermione raised an eyebrow at him, "Wow, Ron, when did you learn to be so gentlemanly?"

Ron blushed, looking down and mumbling softly, "Well... you guys helped us review, so we should at least thank you."

"Alright then." Hermione nodded, linking her arm with Lin Yue's and leading her out of the library.

Harry, following behind, patted Ron on the shoulder with satisfaction, "Well done, buddy, keep it up."

Ron nodded, his face still red, and caught up with the two girls walking ahead.

He had just mentioned that he and Harry would take turns carrying the backpack, but the reality indeed required it.

Lin Yue's backpack was too heavy; she had borrowed as many books as possible from the library, many of which were hefty tomes that looked like they could crush someone.

With a fully packed backpack, as they walked down the stairs to the first floor of Hogwarts and hadn't even exited the castle yet, Ron was already a bit out of breath and felt his shoulders aching.

"Merlin's backpack... I feel like this bag contains the entire Hogwarts library."

Seeing this, Harry smiled and shook his head, reaching out to grab Lin Yue's backpack from Ron. "Let me take it, Ron."

Ron didn't insist and nodded, letting the backpack slide off his back.

As soon as Ron set down the backpack, Harry's expression changed instantly; his eyes widened as he looked at the bag. This backpack... is so heavy! Swallowing hard, Harry hoisted the backpack onto his shoulder. Just as he was about to call out to Ron to keep walking, he noticed Ron staring blankly at his own shoulder.

"Ron, what are you staring at?"

Harry asked in confusion as he walked over, only to see a large area under Ron's collar that was red from the backpack's strap, with some spots looking slightly swollen, which looked quite alarming.

"No way..." Ron murmured, looking down at his shoulder with a sense of existential doubt. He then raised his head to look at Lin Yue, who had already walked a distance away.

If his shoulder looked like this after just a short time carrying her backpack, what must Lin Yue's shoulders look like? Harry followed Ron's gaze and clearly thought of the same thing. He patted Ron on the back, saying nothing, and just pulled Ron along to catch up with Hermione and Lin Yue. He would mention this to Hermione later; he believed she would have a way to solve it.

Unfortunately, when they sat down on the grass, before he could even bring up the small issue of Lin Yue's backpack weight, he was hit with a wave of headache.

"Harry, are you okay?" Seeing Harry clutching his head with a pained expression, Hermione asked with concern.

"I'm fine," Harry quickly waved his hand, "it's just my scar... it hurts a bit."

"Your scar hurts?" Hermione frowned.

"Yeah." Harry replied while holding his forehead.

"Has it hurt before?"

"It has, at the beginning of the school year, Professor Snape looked at me, and at that moment, my scar hurt. It also hurt that night in the Forbidden Forest."

"What does that mean? Does the pain from a magical scar possibly have different meanings?" Hermione speculated, then looked at Lin Yue as if seeking confirmation.

Lin Yue felt Hermione's gaze and turned her head to look at her with a calm expression, speaking in a flat tone, "What's wrong?"

"Um," Hermione pressed her lips together, "Lin Yue, do you know if the pain from a magical scar has any special significance?"

Lin Yue quickly searched her mind for various books she had read, "The pain from a magical scar could be due to the curse associated with the magic that caused the injury, or it could be that the magic cannot be completely healed."

As she spoke, her gaze shifted to Harry, her tone mechanical, "The only case of a magical scar caused by the Killing Curse is Harry's; I can't make any assumptions."

"But personally, I think his situation shouldn't fall into either of those categories."

"Alright..." Harry nodded, covering his forehead, indicating that he understood, "Thank you, Lin Yue."

"I actually think... this scar pain might be warning me that something bad is about to happen."

Harry shrugged, "Think about it, Professor Snape looked at me, and my scar hurt; he really did deduct points from me almost every class afterward."

"When I saw that hooded figure in the Forbidden Forest, my scar hurt; he really did want to harm us."

Ron furrowed his brow and thought for a moment, "That makes sense... but what does it mean that your scar hurts now?"

Harry lowered his gaze, "I'm not sure, but something bad is definitely going to happen, definitely..."

The previous pain from the scar was because of the hooded figure in the Forbidden Forest, and going into the Forbidden Forest was because he went to send off the baby dragon Norbert...

As Harry pondered aimlessly, a sudden realization struck him. Wait, the baby dragon! The dragon egg! Carrying a dragon egg illegally is against the law; who would carry a dragon egg around and even use it as a bet? Understanding the key point, Harry immediately became excited and shared his thoughts with the other three present.

After hearing Harry's idea, Hermione and Ron both gasped sharply. If that's the case, then the other party... Suddenly jumping up, Harry grabbed Lin Yue's backpack and ran towards Hagrid's hut, with Ron following closely behind. Hermione took Lin Yue's hand and brought her along as they all sprinted after Harry.

Lin Yue's face remained unchanged, but her mind had already begun to speculate.

Betting with Hagrid using a dragon egg couldn't be for money; it must be for... information?

But what information could Hagrid have that the other party might need? Lin Yue concluded that the other party wanted information, and then her analysis stopped there.

It wasn't until Harry knocked on Hagrid's hut door and asked him about the person he had bet with regarding how to get past the three-headed dog that Lin Yue's analysis in her mind suddenly connected.

Various trivial details flashed quickly in her mind and were automatically sorted out. At that moment, Harry also mentioned what the centaur Firenze had said when he carried him out of the Forbidden Forest and speculated that the figure in the black cloak in the Forbidden Forest might be Voldemort.

Ron’s face turned pale, and Hermione next to him shuddered.

"But... the Dark Lord is dead, right?" Ron's face was ashen as he looked at Harry in fear.

"Hagrid said... Professor Dumbledore believes the Dark Lord might not be dead," Harry said with difficulty.

"The most likely scenario is that Voldemort is not dead," Lin Yue said in a flat tone while her mind continued to sort and analyze.

"According to the records in the Hogwarts library, no one has ever found Voldemort's body, and his cause of death is speculated to be the rebounding Killing Curse from Harry."

"The Killing Curse does not turn a person to dust; it acts on the soul. Therefore, I believe the most likely scenario is that Voldemort escaped for unknown reasons and entered a weakened state, disappearing without a trace."

Hearing Voldemort's name mentioned several times, Ron and Hermione's faces grew even worse, while Harry remained relatively calm.

"So, it really could be him."

"Additionally," Lin Yue said, her gaze calmly sweeping over the other three present, "the known item in the restricted area on the fourth floor is the Philosopher's Stone. The three-headed dog guards the Philosopher's Stone, and the figure in the black cloak who was trying to extract information from Hagrid about how to get past the three-headed dog must want the Philosopher's Stone."

"The Philosopher's Stone can produce the Elixir of Life, which has effects similar to unicorn blood. Therefore, it can be inferred that the figure in the black cloak in the Forbidden Forest and the one who was questioning Hagrid are the same person."

As Lin Yue continued to output her analysis, which was meticulous and expressionless, Ron and Harry felt a chill run down their spines, while Hermione bit her lip tightly, feeling a pang in her heart.

"They need unicorn blood, the Philosopher's Stone for life extension, and they have great hostility towards Harry, suggesting that the weakened Voldemort or someone related to Voldemort is the opponent."

As Lin Yue spoke, her mind continued to rapidly select related items. "During the first Quidditch match, the likelihood of Professor Quirrell harming Harry is the highest; the figure in the black cloak can be inferred to be Professor Quirrell."

"His relationship with Voldemort is unknown, and his method of contacting Voldemort is also unknown. I can only analyse it up to this point."

After Lin Yue finished speaking, she closed her mouth. Harry and Ron stood there in a daze, while Hermione took a deep breath, rushed forward, and hugged Lin Yue, her right hand continuously stroking her back.

"Thank you, your analysis is already very good."

However, she really didn't like hearing Lin Yue's analysis; she really didn't like it, just like when she had previously listened to Lin Yue explain those emotions. It was really uncomfortable, a painful tugging in her heart... Being held in Hermione's embrace, Lin Yue expressionlessly raised her hand to return the hug. She didn't understand what was wrong with Hermione and had no doubts in her heart; she just couldn't analyse it.
