After Lynn exhausted himself and his magical reserves were depleted, Professor Green finally shouted "enough" and took Lynn back to Hogwarts Castle.
Back in the Slytherin dormitory, Lynn suppressed his sleepiness and read through the Transfiguration Notes that Professor McGonagall had given him before he eventually fell asleep.
The next day, Lynn woke up early and reviewed the Transfiguration Notes from Professor McGonagall again, especially the section that taught how to apply Transfiguration in real combat situations.
Lynn even practiced in the dormitory. It wasn't until he successfully transformed the blanket into a venomous snake and could control it as if it were an arm that he was satisfied enough to return it to its original state and head to the auditorium for breakfast.
Christmas vacation was the happiest time of the year for the young wizards, but it was extremely grueling for Lynn, who refused to give up even when he couldn't produce a simple luminescent flash in his practical lessons every day.
In the past few days, Lynn had been struggling yet happy. The magical power in his body went through the cycle of draining and refilling repeatedly. Lynn's strength was subtly improving. Under Professor Green's special training, he had reached the level of a typical Auror.
And remember, Lynn was still only in his first year!
Soon, Christmas vacation was over.
In the first Transfiguration class after the holidays, Professor McGonagall taught techniques for turning living creatures into inanimate ones and then gave all the students a cockroach, instructing them to transform it into a quill.
Lynn's silent Transfiguration spell easily turned the cockroach into a quill with intricate patterns on its surface. This surprised Professor McGonagall, who generously awarded Slytherin ten points.
"Well done, Lynn. If you don't have anything else to do after class, could you stay for a while?" Professor McGonagall complimented Lynn happily.
Lynn nodded slightly and agreed, "No problem, Professor."
This Transfiguration class was the last one of the afternoon, and there was still some time before dinner, so Lynn, naturally, had no other plans.
After class, a group of young wizards left the Transfiguration classroom, but Lynn stayed in his seat.
Professor McGonagall approached and asked, "Lynn, what is the maximum level of Transfiguration you can achieve now?"
Lynn waved his wand and cast a silent Transfiguration spell. Five or six tables around him instantly turned into lions, while the chairs beside the tables became venomous snakes.
Lynn waved his wand again, and these lions and snakes quickly rushed toward Professor McGonagall. Just before they were about to reach her, the transformation was undone, and they returned to their original forms.
"Professor, I've read all the Transfiguration notes you gave me and I can use them," Lynn explained to Professor McGonagall.
Professor McGonagall, who had witnessed strong winds and waves, was not frightened by the previous lions and venomous snakes. However, Lynn, a first-year student, achieving such a level of Transfiguration truly amazed her.
Her eyes softened as she looked at Lynn. Everyone would appreciate having a talented and diligent student like him.
Professor McGonagall said, "Lynn, would you be interested in joining my Transfiguration Club? My Transfiguration Club is normally only open to sixth and seventh-year students, but you are an exception. Your Transfiguration ability is already not weaker than your older peers in the club!"
Turning living creatures into inanimate ones was a first-year course, but transforming a large animal like a lion and being able to control its movements in combat was not something an average wizard could do.
Lynn's talent in Transfiguration made Professor McGonagall eager to recruit him into her club.
Upon hearing this, Lynn was thrilled.
Many professors at Hogwarts had their own clubs, such as Professor Flitwick's Charms Club and Professor Slughorn's Slug Club, as mentioned in the original books.
Joining these clubs not only meant that Lynn could further improve his magical level but also gave him the opportunity to make more connections.
Yes, connections!
The reason Professor Slughorn founded the Slug Club was to connect students who could become extraordinary in the future.
"Of course, Professor! I'm curious, what kind of activities does the Transfiguration Club hold on a weekly basis?" Lynn quickly asked.
Professor McGonagall looked at him with relief and said, "The Transfiguration Club is not as demanding as our classes. We meet every Sunday morning to discuss topics related to Transfiguration. Our meetings are very informal, and everyone can speak freely without restrictions."
After explaining the meeting schedule of the Transfiguration Club, Professor McGonagall handed Lynn a new Transfiguration Notebook, which recorded some new Transfiguration knowledge.
Lynn even discovered some theoretical knowledge about Animagi in it.
This way, Lynn successfully joined Professor McGonagall's Transfiguration Club.
It was a pity that Professor Flitwick hadn't invited him to join his club earlier, as Professor McGonagall had. Perhaps it was because geniuses in magic were more common, but geniuses in Transfiguration were rare.
Lynn was not disappointed by this. After all, there were many members of Dumbledore's original Army who had mastered the skill of silent spell-casting, so Professor Flitwick would not be particularly surprised that Lynn could cast a few spells silently.
Perhaps Lynn's silent fire spell and non-wand magic would be the key to getting an invitation to the Charms Club in the future, but Lynn didn't want to reveal his trump card to anyone other than his family and teachers, not even to the Weasley twins. He only showed off his silent spell-casting skills in front of them.
Moreover, Lynn believed he would eventually receive an invitation from Professor Flitwick in a few years, so there was no need to act too hastily.
As time went on, Merlin's woolen socks were replaced with lace stockings.
Under the weekly practical lessons from Professor Green, Lynn's strength continued to improve by leaps and bounds, and discussions about Transfiguration techniques in the Transfiguration Club were also very beneficial to him.
June arrived, and the final exams at Hogwarts were fast approaching.
During this time, even the Weasley twins were less mischievous, as if the entire Hogwarts Castle had been caught in a tense atmosphere of revision.
Finally, the final exam arrived.
The weather was oppressively hot, and the exam room in Hogwarts Castle, with no air conditioning, was even worse.
After the written portion of the test, the practical exam began.
However, the practical exam, which made most candidates cry repeatedly, was as easy as sprinkling water on Lynn.
After all, compared to facing Professor Green every week, controlling a pineapple to tap dance on a desk was simply not that difficult!
