From Azkaban to Hogwarts.

"Yes, Professor!"

All the conscious students shouted in unison.

-

"My head hurts so much..."

Percy woke up and then saw the ceiling.

He turned his head slightly and immediately saw his classmate—after a moment of panic, he finally realized what had happened.

I was just knocked unconscious by the professor.

'A spell… I barely withstood it.'

He was a little frustrated.

The Ironclad Charm, a protective spell, is inherently stronger than offensive spells, but he couldn't withstand a single spell.

'I'm still a long way off…'

He stood up and then saw the professor's face.

"It's earlier than I expected. Let's go in for class."

William nodded to him and then went into the classroom.

Where were we?

"Oh right, it is..."

Shortly after Percy regained consciousness, the other students woke up one after another and saw the large words left on the wall.

【You're awake? Come back to class!】

Then, they obediently returned to the classroom.

"The Silent Spell is best suited for surprise attacks, but it's not recommended for everyday use..."

"..."

"The Ironclad Spell seems simple, but..."

William nodded to each student as they entered, then continued his lecture.

"Alright, get out of class dismissed," William said, looking at the students after the bell rang. "Not bad, much better than I expected. They were all back before get out of class ended."

"Everyone, go back today and write a paper on the Ironclad Curse for me. Submit it next week."

He nodded, turned and left, but then suddenly looked at all the students.

"Oh right, go back and practice the Ironclad Spell!"

"Yes, Professor!"

Chapter 283 Lupin's Course

"Good afternoon, Adams. How's that biting cabbage?"

William sat comfortably at the table and chatted with Adams.

In the morning, Adams mentioned that there seemed to be a problem with his Bite Cabbage—this potion, which sounded like a suitable vegetable, was one of the essential ingredients for Bone Spirits, and the school greenhouse grew a batch of it every year.

There's no way around it, a fracture is considered a minor injury...

“It seems that last year’s batch of mandrakes had some kind of toxic residue left in the soil,” Adams shook his head. “It’s still being analyzed, after all, we don’t have much experience growing that kind of herb.”

In the plant kingdom, many plants secrete toxins to monopolize nutrients in their growing environment, and this phenomenon is even more prevalent among the herbs used daily in the magical world—William was quite aware of this common knowledge—potions and herbs were not originally separated very closely.

“That’s troublesome…” William shook his head. In severe cases, the soil under the greenhouse would have to be replaced.

However, he didn't intend to offer any suggestions—Adams and his colleagues were professionals, and if they couldn't think of this, his limited knowledge was even less likely to be helpful.

“That’s right. We’re still working on it. The soil in the greenhouse took a long time to get to its current level,” Adams said with a troubled look. “Let’s not talk about those unhappy things. By the way, William, I heard you left a bunch of students outside the classroom this morning?”

“It’s just telling them about the cruelty of the wizarding world in advance,” William shook his head. “They’re all eager for the internship, and they’ve almost lost all their vigilance. They really think there are no bad people in the wizarding world.”

"You're really something."

Adams chuckled. "It's a good thing you came to school late. If I had a professor like you when I was a student, I probably would have been sleeping in the hallway before graduation."

"You're overthinking it, Adams."

Singed, who was standing next to him, interrupted him, "Could you please push the apple pie for me?"

"Ok?"

Adams took the plate and looked at him curiously for a hundred years.

“Thank you,” Singed said very politely, “but I still have to say, your score is simply not high enough for the advanced class.”

The two looked at each other, then burst into laughter like madmen, which drew a glare from Professor McGonagall, finally quieting them down.

Seeing the two of them like that, William couldn't help but laugh, and then looked at Lupin next to him.

Lupin's complexion was much better than when William sat down.

This new professor, who hasn't even started teaching yet, has adjusted his schedule to the most demanding level for various reasons.

Today is Thursday, and this afternoon is for the four colleges of the third year. Tomorrow, it's another whole day for second-year and third-year students. Just thinking about it makes me feel like I'm going to collapse from this overtime schedule.

William could guess the reason to some extent—he was putting too much pressure on his new colleagues.

Last year's incredible OWL results not only dispelled all doubts about him, but also put immense pressure on subsequent professors.

Because of last year's results, he was able to try changing some of his teaching methods according to his own ideas, while the new professor had to work hard to prepare for his first class.

Others can comfort him, but William absolutely cannot be comforted; that would only increase his stress.

I hope he'll be alright.

William silently offered his blessings, then watched Lupin finish his meal and leave.

"William, what do you think of Professor Lupin's class?"

After Lupin left, Adams leaned over and asked, since he started school later than Lupin, who had become a prefect in Gryffindor not long after entering the school.

"It should be very good. Professor Lu Ping's education is definitely more systematic and professional than mine, and his abilities are worthy of that professional education."

William nodded, giving himself the best possible assessment.

-

'Calm down, calm down.'

Lupin reminded himself of this, and he did.

Although before coming to the school he thought his primary goal was to protect James's child and then catch that guy Black, now he really wanted to do well in his first class and prove himself.

As a werewolf, even if he was a Hogwarts prefect and had excellent grades, it was still of little use.

After receiving a large sum of money from the school, he donated most of it to others who had also unfortunately become werewolves.

'Although I'll most likely lose them after being exposed, I still want to impart something to those students...'

He meticulously prepared for his first lesson, even moving his schedule to the back, just so he could better familiarize himself with the environment after a long absence from Hogwarts and make his first lesson as perfect as possible.

'call…'

He took a deep breath, then exhaled before pushing open the classroom door and stepping inside.

There are quite a few students…

However, he did not feel nervous. On the contrary, he became more adept at it. His memories of being a prefect unconsciously surfaced. In his eyes, those students were not much different from the troublemakers of more than ten years ago.

“Good afternoon,” his voice was unusually steady, even a little too calm. “Please put your books back in your bags. Today is a practical lesson, so you only need your wands.”

"Wow!!!"

The children below gasped in surprise, which made him feel even more familiar with the place—it was still a Hogwarts classroom, still Hogwarts Castle, still a group of young children, and even—he was still the one in charge of these children.

“Great! Now that everyone is ready, would you like to follow me?”

The students stood up like the troublemakers from before, and followed him closely as he left the classroom.

'I caught two guys in this corridor who used dung balls…'

The corridor also became familiar, which made Lupin even more familiar with it.

'Just missing…'

Just as he remembered, the ghost, or rather the spirit, appeared, exactly the same as it had been more than a decade ago.

Peeves was over there, floating around as always, playing the same pranks that hadn't changed much in over a decade—he was floating upside down in mid-air, stuffing chewing gum into the keyhole closest to him.

"Ha, Lupin!"

Peeves shouted with delight and began singing that old, worn-out tune—it seemed to have been composed by the Slytherin kids back then? Because he had severely punished those students who broke the rules many times?

"Stupid and muddle-headed Lupin," sang Pippi the Ghost, "Stupid and muddle-headed Lupin, stupid and muddle-headed Lupin—"

'Still the same tune…'

He couldn't help but smile, and immediately recognized what the room was used for.

“If I were you, Peeves, I would take the gum out of the keyhole,” he said cheerfully. “Mr. Filch won’t be able to go in and get the broom.”

However, Peeves completely ignored him, humming the tune to itself as if it weren't some old, worn-out thing composed by a Slytherin student more than a decade ago. As it was nearing the end, it added a new twist—blowing a loud "wet raspberry."

“Alright,” Lupin shook his head, sighed, and then looked at the children behind him.

“This is a useful little spell,” he told the class. “Watch closely.”

"Vadishu!" Lupin shouted the spell, then pointed his wand at Peeves.

The small piece of chewing gum shot out of the keyhole like a bullet and went straight into Pippi's left nostril.

The little devil immediately turned away and rose sharply, cursing all the way.

'The usual.'

"Great job, sir!"

A child behind shouted, just like before, "Great job, prefect!"

“Thank you, Dean.” He looked at the boy’s face and instantly remembered his name—because he had been a prefect, he was quite confident in his ability to remember names and associate them with faces.
