From Azkaban to Hogwarts.

'But... I can go too, right?'

William was a little confused. Logically, it would have been better for him, the person involved, to participate in the simulation, so why was he left in the principal's office?

In other places, one might say it's due to distrust, but who would leave someone they don't trust alone in their office?

However, William soon understood why.

"Professor William."

The mural on the wall suddenly spoke—it was one of the past principals.

"Interested in making a deal that doesn't violate school rules?"

“Regarding our family’s sole heir—” the painting said, “if you’d like, I think we can sign a contract.”

Chapters 345: Returning to School and the Approaching Semester

Europe has three major magic schools: Hogwarts, Durmstrang, and Beauxbatons.

But this does not mean that there are only these three magic schools—each magic school has gradually developed from scratch. For example, the Ilvermorny School of Witchcraft and Wizardry in the United States was established and developed in the United States in the 17th century by the mixed-race descendants of the Gaunt family, descendants of Slytherin.

In the beginning, Ilvermorny School of Witchcraft and Wizardry consisted of only a dilapidated stone house, two professors, and two students—and wands so rudimentary they were an insult to Slytherin himself, which have since transformed into snakewood that still grows luxuriantly.

This information was provided by the school—not every magic school likes to expose its secrets, and the general public simply cannot obtain this kind of information.

Take Durmstrang, the school William and his group visited this time, for example. They were so stingy that they didn't even disclose their address, so students didn't even know which country they were studying in after they finished their studies.

Don't be fooled by the school's recommendation that William and his classmates learn German; it's purely Durmstrang's linguistic bias stemming from historical issues—although Grindelwald was expelled by Durmstrang back then, as the first Dark Lord's career flourished, speaking German became fashionable inside.

Although Dumbledore defeated Grindelwald in the duel, the school has no intention of changing it this time—Dumbledore is a pure Hogwarts student.

"Okay, I understand the general situation, but the final question is—how can we teach a class if the students don't know anything about it?"

William listened to the other professors' supplementary remarks and asked out of curiosity.

"Wait for the ship to pick them up; they have a large ship that they've been using until now—"

Professor Corey patiently explained, "It's a wooden boat, what era are we living in? Boats made of wood, tsk tsk..."

'The Hogwarts Express isn't much better...'

William couldn't help but want to complain, but he managed to hold it in with sheer willpower—now was the time to unite against a common enemy, and it wasn't the time to complain about the Hogwarts Express not living up to its name.

Although he was more inclined to criticize the Hogwarts Express, which looked like a train but was actually powered by magic, and said that the steam chimney of the locomotive was just for decoration and looked like a hot pot restaurant on a train, it was indeed inappropriate at the moment.

"If the time is correct, there are five minutes left."

The Ministry of Magic staff member glanced at the time and then confirmed—as for Professor Corey's earlier complaint, he gave a look as if he hadn't heard a thing.

"Wait, Professor, it won't be long." Adams chuckled, trying to smooth things over. "Hopefully we can get some good seeds this time. There are a few herbs that can only be openly grown here because of their uses."

It didn't take long, only a few minutes, before William's hand reached for the wand, and then the calm lake in front of them began to ripple.

'Strange...why is the water like this?'

William instinctively took a step back and then observed the surface of the water—it looked like something was about to emerge from the water, but the water flowed as if something was being sucked in.

'Spatial movement similar to Apparition?'

'Was it draining a section of water and replacing the hull, or...'

Such an idea was tempting, but William's knowledge was insufficient for him to understand the problem—although he had been working hard on Apparition, an escape spell, it was not his main focus.

Chapter 346 Learning and Progress

"yawn…"

"... "

On the first day of the new semester, the corridors were filled with sleepy students, and yawns seemed to be contagious, spreading among the crowd.

April's bright spring sunshine, combined with the lingering laziness of students after the holidays, meant that even in Professor McGonagall's class, some students would doze off.

Hermione was one of them. She walked at the front with a blank expression, looking as if she was angry with someone. As she passed by, the surrounding students even lowered their voices and their drowsiness was swept away.

Harry and Ron even had to jog a few steps occasionally to catch up with their friend, but even so, they still managed to find time to whisper to each other.

"She can't be that bad... She just accidentally fell asleep in class..."

Ron jogged along, whispering to himself. The sun was shining so brightly today that many students were unconsciously leaning on their desks. He himself had even killed the beetle that needed to transform with a single wand, without thinking it was a big deal.

“Her schedule,” Harry didn’t think it was a big deal, but he figured it was best to keep his voice down for now, “Don’t forget, Ron, her schedule is horribly incomprehensible…”

“That makes sense,” Ron nodded. “Her schedule is as terrifying as Percy’s back then… To be honest, Percy was pretty neurotic back then too. Is this some kind of contagious curse?”

“Contagious curses are all malignant curses; it’s normal for people to die from them, as the professor said,” Harry said instinctively.

“Well, it’s the professor again…” Ron shrugged. “Percy too, Fred and George too—Mom was saying all Easter that it was a miracle they were at the top of the class in fifth grade!”

“Oh, right,” Ron said, as if remembering something, “Mom asked me to bring you some bacon and a sweater, but I forgot yesterday!”

He and Harry did meet on the train back to school yesterday, but because many people were playing cards together (after all, except for the fifth graders, there was very little homework, and the Easter break didn't require making up for summer homework like the start of the school year), everyone forgot about it.

"Sirius and I bought a lot of things, and they're still in the trunk," Harry said, remembering the pile of gifts in the trunk—they were so tired from playing yesterday that they lay down as soon as they got back and completely forgot about the gifts.

"Speaking of which, how was your holiday?"

“That was cool!” Harry said without hesitation. “We also went to Sirius’s old house, but…”

"How long are you two going to dawdle? The next class is about to start!"

Hermione's voice came through, and she glared angrily at Harry and Ron.

'There are still more than twenty minutes left...'

The two of them thought the same thing at the same time, but neither dared to object.

"Excuse me... could you move aside?"

As I passed through the corridor, a professor's voice rang out from around the corner, and the next second, a large bundle of fresh, neatly tied herbs floated overhead—the roots of the herbs were cleaned thoroughly, with hardly any soil.

Then, a burly professor followed, wand in hand. He glanced at the three with a smile, and after realizing they weren't his students, he used his wand to manipulate the herbs and continued onward.

"It's only April, isn't it?"

"Except for a few particularly rare ones, greenhouse-grown herbs don't really have to worry about time."

Hermione seemed to be in a better mood and began to explain.

"How did so many herbs get transported here?"

Ron looked on in surprise. "What new potion has Snape prepared? That can't be right, Potions class isn't today."

“Judging from the design, it should be for making healing potions—” Hermione thought for a moment, “Besides, it’s not just us who need to take potions class, not to mention that the potions classroom is in the basement, this is on the second floor.”

……

William's office door was open, and the windows were open, but even so, the grassy smell emanating from the three huge crucibles still filled the entire room.

While simultaneously brewing three large cauldrons of potions isn't a huge challenge, it's not something an ordinary wizard could attempt.

'To be honest, the office is really not a good place to brew potions.'

William looked at his owl, which was huddled in the corner and occasionally let out a low, protesting hoot, and shook his head.

Before I got this potion, I used to brew it in the office. As long as the ventilation was good, there weren't any major problems. With proper mixing, the residual smell of the potion wouldn't be too strange, and it would even have a pleasant herbal aroma.

'Next time, I'll just set up the cauldron in the classroom. Today's potion actually smells a bit like fresh grass... I just brewed a bit too much.'

“William!”

Adams' voice rang out from a great distance.

"The herbs are very stable, just come in directly."

William responded remotely: No matter how skilled he is at brewing potions, he always takes precautions when brewing them.

A large bundle of fresh herbs barely brushed past the door as it entered, followed by Adams.

"The smell of green grass—a healing remedy?"

Adams sniffed and looked at the three enormous crucibles.

"If Professor Snape saw this, he'd kill you! You're cooking up dragon dung like this..."

???

Did I provoke you?

This is three pots of magic potion meant for students, how did you turn it into boiling dragon dung? Is that even possible?

Furthermore, why would you cook dragon dung for no reason?

Perhaps William's gaze was too aggressive, Adams immediately began to explain.

"Some special herbs are not very effective when simply mixed with dragon dung fertilizer. Higher-end fertilizers require further processing—what's with that look you're giving me? We're not boiling them in a pot. When they're piled up there fermenting, the internal temperature gets very high, just like boiling. Of course, we'll use magic to provide some temperature assistance..."

So how is my potion-making the same as yours?

William rolled his eyes in annoyance—this was supposed to be a high-level potion-making technique, how did it end up like this in Adams' mouth?

"Fresh herbs, can you handle that?"

"The efficacy of the medicine is somewhat unstable, but theoretically it should be more effective. However, because it is difficult to use, most people prefer the processed version."

William inspected the herbs. "This should provide more than enough supplies."

"With so many healing medicines, are you planning to send them into battle?"

"How could that be? It's just about learning how to heal. Hagrid brought over a few trolls, and I'm going to let the students practice and see what they've learned this year."

"A troll, huh? That's certainly interesting."

The troll cannot deal magical damage. With the professor watching over it, it can only cause superficial wounds, making it very controllable.

"With so many potions, how many grades are you planning to have participate?"

“Whoever loses drinks—” William shrugged. “I had to go through a lot of trouble to get those trolls approved. Professor Lupin’s method really works.”
