In the center of the hall, hundreds of candles were burning. The sky on the ceiling was like black velvet, and not a single star could be seen.

Harry, Ron, and Hermione stood in the crowd of Gryffindors, whispering to each other.

"Harry, have you finished your form?" Hermione asked him.

"Almost." Harry said vaguely. To be honest, he had only filled out one-third of his form.

Half a month ago, after the last dueling class, Hermione told him that sparks from the tip of the wand were a sign that the Disarming Charm was about to succeed, so after returning to the common room, he couldn't help but drag Ron to practice with him for half an hour.

Ron, who had been unsuccessful and was extremely sleepy, asked him to pretend that he was Malfoy, or Snape.

As a result, he successfully used the Disarming Charm.

Hermione was very envious when she learned the news the next day, "Harry, you are a genius! I dare say no one of my peers can do this."

Harry said embarrassedly, "I have a special feeling about this spell."

The little witch took a piece of paper from her schoolbag, "Let's go over the evaluation criteria given by Professor Happ."

Harry was stunned: "Hermione, I haven't had time to look at it..."

...

Ron couldn't help but interrupted, "Harry's Disarming Charm is already very proficient. He can succeed eight or nine times out of ten. Unlike me..." He suddenly made a bitter face: "Only one or two times out of ten."

Hermione took out a parchment from her robe, and the table on it was filled with data. She said anxiously, "Although I can use it, this, this, and this standard are just barely up to standard. What if I wake up one day and suddenly can't do it?"

Neville, who had been listening for a long time, humbly asked Hermione: "Hermione, what should I do if the form is filled out but I haven't mastered the spell yet?" Hermione

: "Uh..." After a long pause, she said uncertainly: "Have you tried to break down the exercises?"

"Of course I tried, but two-thirds of my items did not meet the standards..." Neville's round little face wrinkled into a ball, and he said pitifully: "I'm too stupid, maybe Professor Snape is right."

"Don't lose heart, Neville. I can help you sort out the parts you are not good at." Hermione said .

"Thank you, thank you, Hermione."

Harry also comforted him and said: "Neville, we can practice together."

"That's right, don't care about what Snape said, your Herbology class is great." Ron said. "Neville, believe in yourself. You are an unpolished gem that will shine brightly one day."

Frankly speaking, after going through the test of Lockhart, he could say nice things easily now.

Neville's face quickly turned red, and he was even a little flattered.

He was a little embarrassed and stammered, "I just like to play with flowers and plants. My grandma has a lot of flowers, and I take care of them during the holidays."

"You see, this is your advantage." Harry encouraged him.

On the other side, Felix stood at the door of the auditorium, waiting for several professors to arrive.

Professor Flitwick arrived first. He changed out of his usual wizard robes and wore a close-fitting men's suit. His hair was very neatly ironed.

"Filius, you look great today." Felix praised.

Flitwick was in a good mood, "Thank you, Felix. This is what I wore when I won the duel championship."

The two chatted casually.

"Felix, have you made any progress in your research on that magic?"

"It can barely be used, but to be honest, it's too incomplete. I can even say that it's a simplified spell mixed with ancient magic ideas..."

"Ahem! Felix, there's nothing we can do. There are too few ancient magics that can be passed down intact."

The two discussed the feasibility of replicating ancient magic, but a good cook can't cook without rice. They have too little information at hand, and the magic world has no common research ideas at all.

Felix thought that if he mastered enough magic runes, one day, it would be very easy to restore this magic.

I just don't know how many years it will take.

He has quietly lowered the priority of this matter and is ready to let nature take its course.

Soon, Professor McGonagall and Snape came together. Perhaps Felix's eyes were too obvious, and Snape couldn't help but stab him. "What are you thinking about, Felix?"

"Nothing, I just thought you would count the time to come here." Felix said a little embarrassedly.

When the four professors arrived, Felix got down to business: "My idea is that this duel class is mainly about demonstration. The four of us will each introduce the most essential parts of our views on duels."

"In subsequent courses, I will invite different professors in stages so that you can fully explain your ideas."

Flitwick was the first to express his opinion, "Of course, no problem."

No one else objected.

So when the four professors appeared in the hall at the same time and walked onto the gilded stage, the young wizards were shocked.

Ron groaned: "What day is today?"

The audience was excited and hundreds of students were buzzing. The young wizards of Ravenclaw and Gryffindor burst into applause to welcome the dean of their college.

"Why don't I see Professor Sprout?" A second-year Hufflepuff wizard asked.

"Ernie, Ms. Sprout doesn't care about this..." said a senior.

The other three professors tacitly did not speak and looked at Felix at the same time.

Felix stood up, and he blessed himself with a loud voice: "We are honored to invite Professor McGonagall and Professor Flitwick today. They are willing to show you more possibilities of duels. Cheer up, little wizards!"

The audience applauded like a festival, and Harry's palms were red from clapping.

"Do you think Snape doesn't want to do it anymore?"

"Although I think you are overthinking it, this is a good idea!"

Then, after some refusal, Professor McGonagall stayed on the stage, and the other three retreated to the stage.

Flitwick pulled out a handkerchief, turned it into a high platform, and stood on it himself.

Professor McGonagall clasped her hands tightly together, and she looked at everyone with a serious expression, and the crowd gradually quieted down.

Everyone was curious about what she would say. After all, in their minds, Transfiguration had little to do with dueling.

Professor McGonagall cleared her throat, looked at all the students calmly and said, "Transfiguration is a profound magical subject. It can do many incredible things. In this regard, the best one is your Headmaster Dumbledore."

"That's new." Ron muttered in the audience. "Don't tell me that he defeated the Dark Lord with Transfiguration."

"Of course, that requires advanced magical support. It's difficult for you to do that." McGonagall said, "The significance of Transfiguration to you is not the strength of its power, but the enrichment of your means."

"The core of Transfiguration is change, change at will."

Professor McGonagall drew out her wand, raised her arm straight, and a chair piled in the corner flew over.

The chair turned into a big black cat in mid-air. It landed on the ground swiftly and lightly. Following the command of Professor McGonagall's wand, the big cat circled around her quickly.

The next second, it suddenly jumped up, and its body expanded rapidly, transforming into a majestic lion, with golden mane reflecting fine light.
