"Maybe Professor Lupin...hiss~"

The sudden cold wind blew into Ron's collar, making him swallow the rest of his words. He looked at the window of the lounge and carefully picked up a piece of broken glass: "There's a hole here, no one fixed it?"

Hermione said impatiently: "It's just a spell, please do it."

When they returned to the dormitory, Ron said to Harry: "Maybe it was her cat who did it. I think it's a little strange, especially the way it looked at me..."

Harry didn't continue this topic, nor did he tell Ron that he had thrown Crookshanks out of his bed two or three times. In his mind, the cat seemed to be particularly nostalgic for the taste of Scabbers. Even after he disappeared, it often came to visit. Maybe it just regretted not having a snack?

However, Harry couldn't guarantee that if Scabbers was still there, he would be stimulated to suddenly become a dark wizard. Maybe he just left because he couldn't stand Crookshanks' harassment. He thought that to some extent, the cat saved his and Ron's lives.

Harry was taking off his clothes while looking for a new topic. "By the way, what were you going to say?"

Ron put down his hand that was taking off his shoes, frowned and thought carefully. "I was thinking that maybe Professor Lupin was going to use your Dementor doll to replace the Boggart."

After a few seconds, Harry suddenly realized it. He said excitedly, "You are right. Professor Happ wrote on the card that the doll can help me. I originally thought that I could use it to overcome my fear of Dementors and avoid accidents in Quidditch matches. Now it seems that Professor Happ has long anticipated such a day."

Ron smiled and changed into pajamas. "But it doesn't make much difference. You used it to convince Wood to let you continue to participate in the competition. Remember, he almost fainted when he saw this thing for the first time..."

Even though Ron's words were a bit exaggerated, Harry couldn't help laughing, especially when he thought of the sturdy Wood curled up in the back of the chair like a kitten.

A bed was separated, and Neville said sleepily, "Harry? What happened?"

"Nothing, go to bed quickly." He said hurriedly.

Lying in bed, Harry thought hopefully that he would not miss the next Quidditch practice, just like Hermione never missed any elective class - it was magical, but he only wanted the result.

...

In the following days, in addition to attending classes every day, going to the library, and studying the Pensieve borrowed from Dumbledore, Felix spent a long time sorting out the teaching steps of the ancient magic - Illumination.

This was the final reward he prepared for the club. Although this magic can only be regarded as an infinitely enhanced version of fluorescent flashes, it is satisfactory in terms of effect and safety. The

only consequence of this magic getting out of control is to drain the magic power of reckless learners, which is much friendlier than those who were backfired by the spell, burned into a pile of ashes, or drained of water and turned into mummies.

Felix plans to split this ancient magic, integrate the knowledge into the next gathering, and teach it after the exams of this semester are over.

In addition, his communication with Nick Flamel resumed again. Although the two only communicated through photos, he keenly sensed that Nick Flamel's words were full of decadence. He couldn't help but feel depressed. Dumbledore's words emerged again: Nick's wife might not survive this winter...

But Nick Flamel avoided talking about it, and he could only pretend not to know to avoid opening the old man's scars.

Maybe he could discuss with Nick Flamel and live with him for a while during the summer vacation.

During this period, Mundungus contacted him several times and sent him several ancient alchemical products. He also took out an exquisite silverware. Felix judged from the workmanship that the silverware was made by goblins. This kind of thing has always been valuable. It can be seen that the owner often plays with it. Felix guessed that it might be from a pure-blood family.

Mundungus tentatively asked if he wanted more. He had a stable supply of goods, which made Felix more certain. He couldn't help but sigh that some pure-blood families also had some superficially glamorous ones, but they secretly started selling their property.

In the first duel class in January, Felix explained the rules of the small duel competition and arranged for some senior students to demonstrate. There were not many restrictions except that the use of dark magic, semi-permanent transformation, high-risk curses and potions were not allowed.

"This competition will be as close to reality as possible. The venue is not a ring. After research by several professors, we decided to make full use of classroom 7. Yes, it was changed from the practical classroom of the ancient magic class."

"There is still a month before the duel competition officially begins. You can make adequate preparations."

In this duel class, in addition to the news revealed by Felix, the most eye-catching one was Neville. His silent stun spell successfully knocked down several opponents, which shocked those who knew him.

Neville's heart was pounding. This was the first time he won so cleanly. Seeing Harry giving him a thumbs up, he grinned. After being awakened, Seamus Finnigan hit Neville's chest exaggeratedly, "Hey man, did you take some strong medicine?"

Although everyone was happy for Neville's progress, his change also made many people feel a sense of crisis. The most intuitive thing was that the duel study group formed by Harry, Ron and Hermione became popular in a small area.

In an abandoned classroom, Ron said with determination: "Come on, Harry." A small group of people surrounded him, making his expression look even more tragic.

Harry hesitated, but still obeyed. He pointed his wand at Ron and shouted: "Quickly imprison!" A magic rope wrapped around him, tying him up from head to toe, and Ron fell on the mat with a "bang".

He ran over, lifted the spell, helped Ron up, and asked in a low voice: "Are you coming again?"

"Again, I want to feel your magic a few more times - hiss~" Ron said with a grin, "Has your magic mutated? I feel like my butt has been pierced by a spike."

The students surrounding them all took a step back, and several girls - Lavender Brown and Parvati Patil looked at them with disgust.

Harry explained in a panic: "No, his skin should be swollen, so there is a tingling sensation. I have experienced it -" He stopped, feeling that he was making things worse.

This time, even Ginny looked at him strangely.

Harry gave up explaining dejectedly, glared at Ron, and said unhappily: "Are you ready?"

"Wait -"

"Bang!"

Ron fell to the ground again, and Harry said sincerely to others: "You can check, there are definitely no spikes..."
