Lin Yue stayed at St. Mungo's Hospital for Magical Maladies and Injuries for a whole week. Although she expressed on the morning of the third day that she had mostly recovered and could return to Hogwarts for classes immediately, this suggestion was unanimously rejected by the doctors and nurses at St. Mungo's.

"You were hit by a Cruciatus Curse; at the very least, you need to rest for a week. Don't worry about your studies during this week; the coursework at Hogwarts isn't too heavy. Just stay here and relax," said the nurse, firmly pushing Lin Yue back onto the hospital bed. She also reported to Professor McGonagall, who came in the evening to explain about Animagi.

"This child is too eager to learn. Today she said she wanted to be discharged to return to Hogwarts for classes, and I had to force her back onto the bed. Professor McGonagall, you need to have a good talk with her; she really needs to rest after being hit by the Cruciatus Curse."

"Alright, thank you. I will talk to her properly. You can go back to your duties now."

Professor McGonagall smiled and thanked her before opening the door and entering the hospital room.

As she walked into the room, Professor McGonagall took off her wizard hat. "Good evening, Miss Lin Yue."

"Good evening, Professor McGonagall," Lin Yue said, looking directly at her and politely nodding in greeting.

"I heard from the nurse that you mentioned wanting to be discharged today?" Professor McGonagall sat down in the chair next to the bed, looking at her gently.

"Yes, I have recovered. My priority is myself, and studying comes second. I should return to school to continue my studies," Lin Yue said in a monotonous, mechanical voice.

Professor McGonagall lovingly reached out to smooth Lin Yue's hair. "You still don't care enough about yourself. The effects of the Cruciatus Curse don't just go away because the pain has subsided."

"You need to rest to eliminate the negative effects brought on by the Cruciatus Curse. It's not just physical; it's also mental."

Lin Yue blinked, her voice showing no emotion. "I haven't suffered any mental harm; I have no feelings about that."

"That doesn't mean there isn't any, good child. You just don't realize it yet."

Professor McGonagall shook her head. "You should stay here for a while. I don't want to wait until you've regained your emotions only to be entangled again by the negative effects of the Cruciatus Curse."

"As for your studies at Hogwarts," Professor McGonagall raised an eyebrow and looked at Lin Yue, "I think it should be fine even if you don't attend classes."

"Of course, I won't say that at school, lest some classmates decide they don't want to attend class because of it."

Lin Yue instinctively had a thought flash through her mind: not wanting to attend class? How could that be possible?

Studying and attending classes are the duties of a student; the idea of not wanting to go to class simply cannot exist among students, no matter the circumstances.

However, she should still listen to what the professor said, so she nodded without any hesitation.

"Alright, Professor McGonagall, I will cooperate with the recovery and stay at St. Mungo's until you and the doctors there think I can be discharged."

"Sigh..." Professor McGonagall rubbed Lin Yue's head; the child's rigid demeanor was truly uncomfortable to look at.

I hope Granger can recover soon; only she, along with everyone at Hogwarts, can truly change this child.

"Alright, Miss Lin Yue, do you have any questions about my Animagus notes?"

After hearing Professor McGonagall's "instructions," Lin Yue obediently stayed at St. Mungo's to recuperate.

It wasn't until a week later that the doctors at St. Mungo's and the professors from Hogwarts allowed her to be discharged and return to Hogwarts to continue her studies.

A week was enough time for many things to happen, including Harry's arm turning into "rubber" and then returning to normal.

Lin Yue patiently explained the homework questions to Harry and Ron, who had come to ask for help. Perhaps it was because they felt they couldn't waste Linyue's hard work, or maybe it was because three older Ravenclaw students were sitting nearby. This time, the two boys didn't resort to their usual shortcuts of not listening and just waiting for Linyue to give them the answers. Instead, they diligently learned the relevant knowledge bit by bit and then wrote it down on parchment to complete their homework.

After watching them finish their assignments and confirming there were no issues, Linyue lowered her head to continue reading Professor McGonagall's notes on Animagi. However, it was clear that her friends, whom she hadn't seen for a week, had plenty of topics they wanted to discuss with her.

“Lin Yue…” Harry hesitated as he looked at her, “Do you think it's possible for someone to accidentally use the bone-repairing spell as a bone-extraction spell?”

In fact, he had wanted to ask this question for a long time. He knew that Lockhart was a complete fraud. So, when Lockhart wanted to perform the bone-repairing spell on him, he firmly refused. Unfortunately, he still ended up being “victimized” by Lockhart.

With one spell, all the bones in his arm were gone. The painless extraction of all the bones from his arm—honestly, Harry thought that this was probably harder than just repairing his bones. So, he had some doubts; was Lockhart really trying to harm him rather than just making a simple mistake? The bone-repairing spell, mistakenly used as a bone-extraction spell?

Lin Yue quickly recalled the magic for setting bones in her mind; indeed, there was such a healing magic. However, the magic for extracting bones... Lin Yue reviewed all the books she had read again, but found no trace of this magic.

Her gaze swept over Harry's entire body. "Your bones seem to be fine?"

Lin Yue spoke with absolute certainty; she was completely sure that all of Harry's bones were normal.

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

"Right now... that's indeed the case," Harry nodded with a complex expression.

He then began to recount to Lin Yue, along with Ron, the incident of how Lockhart had extracted his bones.

As Lin Yue listened, she thought and analyzed in her mind. After Harry finished his story, she looked up at him.

"What spell did Professor Lockhart use?"

"Uh..." Harry scratched his cheek, feeling a headache; at that time, he was too focused on the pain to pay attention to what spell Lockhart had recited.

"I remember... it seemed to be ' Brackium Emendo'?" Cho Chang, sitting next to Lin Yue, furrowed her brows, trying hard to recall that phrase Lockhart had said, which wasn't really a spell.

Lin Yue nodded, her brain began to simulate the application of this spell and the resulting scenarios.

She quickly reached a conclusion, "The wizard's magic is quite idealistic, so the 'Brackium Emendo' spell, although not an accurate or formal incantation, can indeed fix Harry's arm if there is sufficient magical power and professional knowledge."

"Very good," Marietta muttered softly, "Gilderoy Lockhart happens to have neither."

"But if there isn't enough magical power and no matching professional knowledge, the 'Brackium Emendo' spell can easily lead to the opposite result."

Lin Yue quickly stated her conclusion, "Since the problem lies with the bones in Harry's arm, without professional knowledge, using such an informal spell like 'Brackium Emendo' could very likely result in the problematic bones disappearing instead of fixing the arm."

"After all, if the problematic bones disappear, then the arm has no issues left, which could be considered as ' Brachio Emendum.'"

"Oh Merlin..." Ron exclaimed, turning to look at Harry, "Thank goodness you didn't break a rib."

Harry's mouth twitched violently twice, and he suppressed the urge to slap Ron.

Taking a deep breath, Harry waved his hand, "It was just a misunderstanding; at least Lockhart didn't intend to harm me..."

It wasn't that he was overly sensitive; it was just that so many things had happened over the past two years, just like this time when his arm was broken, which was caused by that house-elf he had seen before, Dobby.

Yes, this time Harry had heard its name; it was called Dobby.

Thinking of this, Harry decided to share this incident with his five friends as well.

After listening to Harry, Penelope squinted her eyes, "No wonder, house-elves can Apparate within Hogwarts and can remain undetected by wizards. If it was a house-elf, it could indeed tamper with the Bludgers without being discovered."

"But why would it go to such lengths just to get Harry to leave Hogwarts to protect him? Why?" Marietta spread her hands, expressing her confusion about Dobby's actions. This is Hogwarts, with Professor Dumbledore here; generally, it should be quite... safe, right?

Lin Yue's mind raced with thoughts: the early warning during the summer vacation, the identity of the house-elf, the diary that inexplicably appeared in Ginny's hands, Voldemort's relationship with the Malfoy family...

Looking up, Lin Yue blurted out all her deductions. "It is known that the one warning Harry is a house-elf named Dobby. Generally, non-pureblood families do not have house-elves, so the target is narrowed down to pureblood families."

"At the same time, Dobby's purpose is to warn Harry of the danger at Hogwarts, which suggests that he knows in advance that danger will occur at Hogwarts, combined with the fact that house-elves can access their master's secrets."

"It is reasonable to conclude that this danger is brought to Hogwarts by the house-elf's master."

"The danger that has already appeared at Hogwarts this year is the Basilisk, which was released by Ginny Weasley after being possessed by Voldemort's diary."

"However, the possessed diary is likely to be a rare item among dark magical objects, and Voldemort would only give it to a trusted family."

"The scope of pureblood families is further narrowed. Considering that the victim is Ginny Weasley, the range of pureblood families that are also Voldemort's confidants is further reduced, with a ninety percent probability that it is the Malfoy family, meaning the house-elf's master should be the Malfoy family."

"From this comprehensive analysis, I conclude," Lin Yue's gaze turned cold as she looked at Harry, "Lucius Malfoy is plotting to secretly give Voldemort's diary to Ginny, intending to strike at the Weasley family and Hogwarts, and his plan was discovered by the house-elf Dobby."

"Given Harry's adversarial relationship with Voldemort, Dobby believes Harry will be in danger, so he is doing everything possible to prevent Harry from coming to Hogwarts and staying at Hogwarts, in order to protect Harry's safety."

With the entire situation analyzed, Lin Yue closed her mouth again. The other five people present exchanged glances, wondering... did they really find out the mastermind so easily?

How did they come to these deductions and associations?

Shaking her head, Cho Chang was the first to come back to her senses, "If that's the case, Dobby is in great danger now. Lucius Malfoy's plan has failed, and if he finds out that Dobby has betrayed him..."

Before she could finish, Harry suddenly stood up, "I’m going to find Professor Dumbledore for help."

With that, he rushed out of the library. No matter what, Dobby was trying to save him, and he couldn't just stand by and watch Dobby be in danger.

Ron quickly got up and followed, while Cho Chang, and Marietta exchanged glances, thinking that it was just a matter of informing Professor Dumbledore, and that they didn't need so many people, so they remained seated like Lin Yue, calm and steady.

Lin Yue was seriously looking at Professor McGonagall's Animagus notes, while Cho Chang, and Marietta were quietly chatting on the other side.

"Speaking of which, wasn't the Basilisk already dead in the last match? Why did Dobby still want to force Harry to leave Hogwarts?" Cho Chang turned to her momentarily confused friend and lowered her voice to explain, "Don't forget, the last match started the day after the Basilisk died."

"Oh! The news is wrong!" Marietta suddenly realized.

Penelope, sitting next to Lin Yue, noticed that the book she was reading seemed to be handwritten and couldn't help but lean over to look.

She then saw the entire content about Animagus and thought about Lin Yue's pronunciation just now...

Her pronunciation used to be standard, but today it seemed a bit unclear, so was she chewing on Mandrake leaves?

"Lin Yue, are you practicing Animagus?" Penelope asked, and Cho Chang and Marietta immediately shifted their gaze to Lin Yue.

Animagus?! Is Lin Yue practicing such a difficult and dangerous transformation?

"Yeah," Lin Yue honestly nodded, "Professor McGonagall is teaching me."

"Oh." The three older girls simultaneously felt relieved; with Professor McGonagall watching, it would be fine.

In the following month, Harry and Ron occasionally ran to the headmaster's office, listening to Professor Dumbledore say that he was ready to rescue Dobby.

None of them wanted anything bad to happen to such a kind and brave house-elf.

In this month, Lin Yue completed the first step of becoming an Animagus. On the full moon, exactly one month later, she mixed the leaves of mandrake in her mouth with a mouthful of saliva and spat it all into a crystal vial. That night, she let it fully absorb the moonlight and added a series of ingredients before burying the crystal vial underground, ensuring it wouldn’t be exposed to any sunlight.

Immediately after, she pointed her wand at her heart at every sunrise and sunset, reciting the incantation. As the days passed, she gradually felt a second heartbeat. This heartbeat was powerful and vigorous; Lin Yue could sense the strength contained within it, which made her mind feel incredibly at ease.

Finally, two days before Christmas, Lin Yue was met with a storm. Professor McGonagall stood at the spot where Lin Yue had buried the crystal vial, feeling the surrounding storm and couldn’t help but reflect on it. In a short period, Lin Yue had almost mastered the Animagus transformation, and she encountered a full moon with ample moonlight when she first completed the first step.

Just as she was nearly ready and had comprehended the Animagus transformation, the storm arrived immediately. With such talent and luck… Professor McGonagall felt a bit envious of her student. Perhaps the hardships she had endured in the past had turned into the sweetness of the present.

Accompanied by Cho Chang, Marietta, and Penelope, Lin Yue walked out of the castle and politely greeted Professor McGonagall. As the first lightning bolt streaked across the sky, Lin Yue dug up the crystal vial, which contained just the right amount of red potion.

Lin Yue drew her wand and pointed it at her chest, reciting the spell.

" Amato Animo Animato Animagus."

After finishing the incantation, she unhesitatingly opened the crystal vial and swallowed its contents in one gulp.

A strong sensation of pain and a distinctly different heartbeat surged within her.

The pain did not seem to affect her much; her expression remained unchanged.

"Don't resist it, accept it," Professor McGonagall instructed as she and the others stepped back, cautioning them as they retreated, "but at the same time, maintain your own consciousness, don't let the animal instincts consume you."

Listening to Professor McGonagall's words, Lin Yue felt a surge of various instincts in her mind, such as brutality and bloodlust.

The animal form she was about to transform into became increasingly clear in her mind.

What I need is an Animagus that is dangerous enough, powerful enough, and capable of protecting Hermione and everyone else, rather than being consumed by animal instincts.

Lin Yue's consciousness was firm and clear, her eyes shining brightly in the stormy night.

In the next moment, her gaze suddenly shot up, and the four people watching not far away simultaneously gasped in shock. If they didn't know it was Lin Yue, Professor McGonagall might have acted on the spot.

Cho Chang and the others were about to turn and run immediately.

A massive claw stomped on the ground, with the second toe claw raised high, its sharp, thirteen-centimeter-long talon glinting coldly.

There was no doubt it could pierce directly into a person's chest and heart in one strike.

A powerful tail swung violently, sending countless raindrops flying, while the agile front claws clenched and relaxed in front of its chest, the sharpness of which was chilling.

Huff... Two streams of hot air burst from its nostrils, and within its gaping maw were around sixty sharp teeth.

Lin Yue slowly walked towards Professor McGonagall and the three senior students. Professor McGonagall raised her wand cautiously, looking at the prehistoric creature in front of her, which stood two meters tall and was over three meters long.

"Miss Lin Yue... do you still have consciousness?"

Stopping in her tracks, Lin Yue slowly nodded her head, indicating that she was still herself.

Professor McGonagall breathed a sigh of relief and lowered her wand.

Lin Yue tilted her head, following the thoughts in her mind, and let out a roar amidst the storm.

"Roar!"

It was powerful enough, dangerous enough.

This was the best choice her subconscious could make in conjunction with her magic. Her own meticulous brain, combined with the claws, speed, and strength of a Velociraptor, posed a significant threat to the wizards who primarily threatened Hermione and everyone at Hogwarts.

There was a high chance that the wizards would miss Lin Yue, transformed into a Velociraptor, but if they gave Lin Yue an opportunity to attack, even a swipe from her front claws would be enough to kill a wizard.

After all, they were not prehistoric creatures, and did not have thick enough skin to withstand such claws.

Incredibly fast speed and extreme threats was the choice Lin Yue made for Hermione and for her friends.
