Here is the corrected version with grammar and Harry Potter universe elements fixed:
Exhausted and with his magic reserves depleted, Lynn finally heard Professor Green call "stop." They returned to Hogwarts Castle, where Lynn, despite his weariness, suppressed his drowsiness and devoured Professor McGonagall's Transfiguration Journal before finally collapsing into bed.
The next day, Lynn rose early and eagerly reviewed the journal again, focusing on the section about applying Transfiguration in combat. He even practiced in his dormitory. Satisfied only when he successfully transfigured his blanket into a venomous tentacula he could wield like a whip, he transformed it back and headed to the Great Hall for breakfast.
While the Christmas holidays were a joyous time for most students, for Lynn, they were grueling. Professor Green pushed him relentlessly, ensuring no day passed without depleting Lynn's magic reserves to the point where he couldn't even cast a simple Lumos.
These past days were a mix of pain and progress. Lynn's magic power constantly cycled through depletion, replenishment, and depletion again. However, his skills were subtly improving. Whether it was spellcasting or Transfiguration, under Professor Green's special training, Lynn was approaching the level of an ordinary Auror – remarkable considering he was only in his first year!
The holidays soon ended. In the first Transfiguration class after the break, Professor McGonagall taught the technique of transfiguring living creatures into inanimate objects. She provided each student with a cockroach and instructed them to transfigure it into a quill.
Lynn, with a silent Transfiguration spell, effortlessly transfigured his cockroach into an ornate quill adorned with intricate patterns. Professor McGonagall, genuinely impressed, awarded Slytherin ten points.
"Well done, Lynn," she praised. "If you have a moment after class, I'd like to have a word with you."
Lynn nodded in agreement. As this was the last Transfiguration class of the afternoon, he had no conflicting commitments.
After class, as the other students filed out, Lynn remained seated. Professor McGonagall approached him. "Lynn," she began, "what's the most advanced Transfiguration you can perform now?"
In response, Lynn silently cast a spell. Five or six nearby desks instantly transfigured into lions, while the chairs beside them became venomous tentaculas, all focused on Professor McGonagall. With a flick of his wand, these transfigured creatures surged towards her, only to revert to their original forms just before reaching her.
"Professor," Lynn explained, "I've studied and mastered all the Transfiguration knowledge from the journal you gave me."
Professor McGonagall, though seasoned, couldn't help but be amazed by a first-year showcasing such advanced Transfiguration skills. Her eyes softened as she looked at him. After all, any professor appreciates a talented and diligent student.
"Lynn," she offered, "would you be interested in joining my Transfiguration Club? It's typically for sixth and seventh years, but you're an exception. Your Transfiguration abilities are already on par with some of my senior club members!"
Transfiguring living creatures into inanimate objects was first-year material, but transfiguring a large beast like a lion and controlling it in combat was far beyond what ordinary first-years could achieve. Lynn's talent in Transfiguration had clearly impressed Professor McGonagall, inspiring her to recruit him into the club.
Delighted, Lynn quickly responded, "Absolutely, Professor! What are the club's activities like?"
Professor McGonagall smiled with relief. "The Transfiguration Club is less intensive than our regular classes," she explained. "We meet every Sunday morning to discuss topics related to Transfiguration. It's a casual setting where everyone feels comfortable sharing freely."
After outlining the meeting schedule, Professor McGonagall presented Lynn with an advanced Transfiguration textbook containing knowledge even beyond N.E.W.T. level. He even discovered some theoretical information about becoming an Animagus.
And so, Lynn successfully joined Professor McGonagall's Transfiguration Club. He couldn't help but wonder why Professor Flitwick hadn't extended an invitation like Professor McGonagall. Perhaps because talented witches and wizards weren't uncommon, but those with exceptional Transfiguration skills were.
Lynn wasn't disappointed. After all, the original Dumbledore's Army boasted several members who mastered non-verbal spellcasting, so Professor Flitwick likely wouldn't be overly surprised by Lynn's silent spells. Perhaps his silent and wandless Incendio could be his ticket into the Charms Club, but revealing such a trump card felt premature. He'd only demonstrated his non-verbal and wandless abilities to his family and teachers, even holding back in front of the Weasley twins. Additionally, Lynn believed a Charms Club invitation from Professor Flitwick was inevitable – there was no need to rush things.
As time marched on, the cold weather of winter eventually gave way to the warm summer sun. Under Professor Green's relentless weekly practical lessons, Lynn's skills continued to flourish.
The discussions on Transfiguration techniques within the Transfiguration Club also significantly benefited him.
June arrived, ushering in the Hogwarts end-of-year exams. An air of tense revision hung over the entire castle, even silencing the usually mischievous Weasley twins.
Finally, exam day dawned. The weather was oppressively hot, and the non-air-conditioned examination rooms felt even more stifling.
However, while the practical exam left most students wailing in despair, it was a breeze for Lynn. Compared to facing Professor Green's weekly challenges, animating a pineapple to tap dance across a desk seemed like child's play!
With a confident swish of his wand and a silent incantation, the pineapple on his desk began to jitter and tap its leafy crown rhythmically, earning him a surprised but approving nod from the examiner.
As he breezed through the remaining exams, Lynn couldn't help but feel a surge of satisfaction. The grueling training sessions, the countless hours spent poring over Transfiguration texts, and the relentless practice – it had all paid off. He had not only survived his first year at Hogwarts, but thrived.
Now, as he awaited the summer holidays and the chance to reconnect with his family, Lynn couldn't help but wonder what exciting challenges awaited him in his second year.
Perhaps Professor Green would raise the bar even higher, and maybe Professor McGonagall would introduce him to even more advanced Transfiguration concepts in the club. A thrill of anticipation coursed through him. The world of magic was vast and wondrous, and Lynn was eager to explore it further, one spell, one transfiguration, at a time.
