From Azkaban to Hogwarts.

After the twins left, Harry asked, somewhat confusedly—although the cauldron had been filled with other potions, he still had a feeling that if William continued to investigate, the previous pot of love potion would not be able to be kept secret.

“Of course not,” William stared at Harry—'This kid has revealed too much, even though he’s not Hermione…'

"If it were Miss Granger, those basic mistakes could have been avoided. They were trying to improve the potion, but there were too many things in it that violated the rules of potion making. I guess the two of them would have to suffer from stomach problems for a long time before they could fix those mistakes."

William held back from saying the second half of the sentence—given Hermione's personality, she wouldn't have thought of improving potions before encountering a bottleneck.

Although he only took the exam twice, he had a general idea of ​​this top student's personality.

She's far ahead in terms of knowledge, but her spirit of inquiry... well, it's not that strong.

She prefers to learn from what already exists and challenge herself with more unknowns, rather than creating something new.

If we're talking about cultivating immortality, she'd be the type who searches everywhere for secret manuals, quickly masters them, and advances to the next level. The twins, on the other hand, would try to create their own techniques—of course, the twins are the type with enough creativity but lacking in talent and fundamentals. If it weren't for the healing power of the magical world, they could easily end up prescribing their own medicine and dying from it…

'None of them are top-tier geniuses…'

However, there's no need to say such things—it's too discouraging. Wizards who have accumulated enough experience to improve and innovate spells aren't as common as cabbages; there aren't that many.

"So, Professor, what are we supposed to do here?"

Harry watched with curiosity as William continued walking down the hallway after closing the room door.

'I want the room that Tom Riddle and his friends opened!'

...

William ignored Harry and continued walking.

The matter was of great importance, and he didn't want to be distracted by anything else.

once,

twice,

three times.

The door appeared abruptly, just like when Harry had called the Weasley brothers out earlier.

"My guess was right..."

"The room is so small that you can't see any signs of it being renovated... but the cauldron that Harry and the others used is still there."

"The diary Lockhart found and the tiara Ginny found are both here; this room has a preservation function."

"Therefore, it is only natural that the house that was opened decades ago is also there."

"We've found you—the real gathering place for Death Eaters is right here!"

"There shouldn't be any particular danger here, but we should still be careful."

William pondered for a moment, then warned those behind him, "Don't follow me. Stand behind me and don't come in!"

Then he started taking out protective gear from his bag.

Dragon skin gloves—essential.

The suggestion is to wear a cloak of protection against curses: "There shouldn't be any particular danger here, but you should still be careful."

I recommend a spell-resistant cloak.

Chapter 224...tch, they couldn't even draw the ending for Hunter x Hunter...

Protected by double-layered dragon-skin gloves, William opened the door as slowly as possible.

The existence of this room was completely beyond his understanding of magic, just like when he first heard about wave-particle duality in high school—it was simply impossible to imagine or understand with common sense. Cthulhu might also work, but after reading the hotpot version of the introduction, he could never go back…

'Perceiving a person's thoughts, then transforming... and it's permanent magic... it's like connecting to another castle, opening a different room each time...'

But now is clearly not the time to consider these things. The team that occupied the room he opened had indeed killed innocent students before, so it wouldn't be surprising if they set up some vicious traps...

The instant the door opened, William jumped back, and a Barrier Charm slammed into the door—using the spell to push the door open while simultaneously blocking any potential attack.

Sure enough, just as the barrier spell slightly pushed the door open, a violet spell was immediately activated, crashing heavily into William's barrier spell, only to be neutralized by a spell William subsequently cast.

"What is that, Professor?"

Harry, who had obediently retreated a considerable distance, couldn't help but ask—he had never imagined that such a dangerous trap was hidden in this secluded hut.

“A greeting gift,” William replied in a muffled voice through his bubbly hair, “you guys better stay away!”

He stopped preparing the Water of Spring spell—the most common way to destroy traces is with fire traps, and apart from a few special fires, the rest can be easily dealt with with Water of Spring.

'I thought there would be a chain of traps…'

The original Death Eaters and the Dark Lord left the school with ease. William checked the employment records at the time—the school would conduct a simple survey and file the graduates' jobs. Tom Riddle found a job as a shop assistant.

'It's even more satisfying than I imagined, ruining the party venue. What a bunch of audacious bastards.' William commented on the Death Eaters from back then, and then critiqued the magic behind the door used to fend off intruders. 'Clumsy work, still kids who haven't left school...'

Although those original Death Eaters would certainly grow to a level of darkness that even William, who had witnessed Azkaban, could not have imagined, their methods were truly inadequate considering their age when they set the traps.

'If it were me, I wouldn't set up any magic here—' William thought, 'and then set up another one near the limit of the usual roll-in route…'

'But since there are traps on the door, according to them, there should be some here too,' William carefully recalled some of the common traps that Nine Fingers had introduced, and disarmed the traps on the nearby floor.

Clearly, at this point, the Death Eaters' research on traps was not as profound as that of Azkaban's thieves—after all, it was someone else's livelihood.

...

That's all.

William searched everywhere for possible traps, easily eliminating them all. "It seems it wasn't reinforced later... or rather, the Dark Lord himself wasn't that concerned about the first generation of Death Eaters..."

"That's true. After becoming a force to be reckoned with throughout the British magical world, how could they possibly suddenly have the idea to look for traces of what happened back then..."

William carefully examined the place, which resembled an empty classroom. Although a long time had passed, there was no dust in the room—'Is it an automated system that performs routine cleaning? Or did they magically transform it into a replica of the classroom from back then?'

These speculations about the Room of Requirement need to be gradually ruled out. Right now, William just wants to see if any traces of what happened back then have been left behind.

'There's even a blackboard—does the Dark Lord really like being a professor?'

He looked at the blackboard at the front and felt that the room smelled more like a classroom—naturally, the blackboard should be used by the Dark Lord himself, and at most, his deputy could occasionally fill in when he was too busy.

'That's true... As a student, the Dark Lord would definitely love to be standing on the podium, a manager rather than someone being managed...'

William, trying to decipher the Dark Lord's mindset, began counting the chairs—this should be the most accurate number of people.

'There are fewer core Death Eaters than I thought… Is it because there weren't many students who were deceived in the first generation? Or is it because there are fewer students whose bloodlines are recognized?'

'It must be bloodline. That was the Dark Lord's motto when he started out...' William sat in one of the chairs, looking at the blackboard, trying to analyze the Dark Lord's psychology at the time from that perspective—though it was probably useless.

'There's such magic?'

As William sat in his chair and looked up at the blackboard, he was immediately drawn to the enormous, glowing green writing on it—the Dark Lord must have used some kind of magic to make the writing so clear that it could only be seen by sitting down and looking up at him.

'That's right, it's the Dark Lord…'

'That's a true genius wizard, someone whose genius is beyond the comprehension of ordinary wizards…'

'Dumbledore's magic, level 3, still carries a sense of ephemeral vulnerability, as if it could shatter at any moment; the Dark Lord's dark magic, I suppose…'

William shook his head, dismissing the thought of the enemy's strength as pointless—'Over there is the Dark Mark, and on the other side is a blessing, like a student graduating…'

'Pureblood supremacy…'

What a terrible slogan! It immediately lowered William's perception of the Black Lord Group—at least come up with a more catchy slogan!

“He’s clearly a Dark Lord just like Grindelwald,” William couldn’t help but compare him to the previous Dark Lord described in the book he’d found in Diagon Alley, “Look at his slogan, ‘For the greater good…’”

"At least other wizards unite, but you've even split the wizards together. How can you expect to succeed?"

Despite the complaints, William had heard plenty about the Dark Lord's "great achievements" in Azkaban—because his base was small and there were no major conflicts among his supporters, Voldemort's men were actually more insane and ruthless than the previous Dark Lord.

"The blackboard is only good for that kind of magic, but it doesn't have any slogans... Wait a minute!"

William hurried to the blackboard and began studying the spells whose content only appeared at a specific distance—sure enough, to maintain this new spell, a bunch of traces from previous uses appeared on the blackboard, which, due to the magic of the room itself, could still be pulled out little by little like a tangled mess…

'If it were just ordinary chalk and cleaned thoroughly, even Dumbledore wouldn't be able to find a trace, right? The Dark Lord might be more vain than anyone else, even more so than Lockhart—it's just that his talent surpasses theirs, enough for him to fulfill his desire to be different.'

William had never seen such magic on the blackboard before, but as a professor, Hogwarts had some internal documents that explained how to control the writing on the blackboard with a wand—and probably no one else outside the school had specifically studied this.

'Referring to the contents of that book, mastering this magic shouldn't be a big problem—developing such magic is difficult, but breaking it isn't that hard…'

'It's going to be another long-term task...'

Abandoning the blackboard, William began to examine the podium—but found nothing.

'And chairs—the chances of leaving documents behind are slim, but leaving a scrap of paper behind while tidying up is perfectly normal…'

William began to feel around the chairs, carefully examining each one for places where draft paper might be hidden.

'chewing gum…'

'Uh, whose cake wouldn't eat this? It's dried out... Did the Dark Lord really allow it?'

'The chocolate is expired…'

"I've got it, this is it!"

William pulled a neatly folded note from between the chairs; it was written in two different handwritings.

[Graduating and then becoming a shop assistant... Ha, our class monitor?]

He's still a bit short of being a pureblood...

……

The handwriting was tiny, as if it had been produced by a magic wand, and the note was folded very small for easy delivery—but setting aside the pointless conversation, the core content almost made William burst out laughing.

Clearly, at least two core Death Eaters couldn't understand their leader's bizarre decision. After learning that he had decided to become a lowly shop assistant after graduation, they suddenly started looking down on him...
