"This thing is really easy to use." In the principal's office, Phineas Black sighed in a frame next to him.

At the same time, the floating silver mist on the desk was constantly changing, and they could see that William had taken Nick to the magical room, and after passing through the tapestry with the troll stick beating the stupid Panama three times in a row, there was an extra door on the empty wall opposite the tapestry.

William pushed open the door and entered, and that was the end of the picture, which then disintegrated into the swirling silver mist again.

Obviously, this is a very clever alchemy artifact, which can make people aware of everything that is happening inside the castle without leaving their homes.

"This magical device existed when I became the principal, and I used it to discover a lot of secret secrets for the students."

"That's one of the reasons why he's voted the least popular Headmaster at Hogwarts, Black." Hearing Principal Phineas's rather proud words, Principal Dippet couldn't help but complain.

"If you had used this thing more, maybe that kid wouldn't have died!" Hearing Headmaster Duppert's complaints, Phineas shot back viciously, his mouth carrying the usual viciousness of Slytherin.

"Are you as perverted as you are? Who would go to see the scene inside the girls' bathroom! I think you still want to fight, Blake! ”

"You guessed it, I'm just going to teach you a hard lesson."

"Don't talk big, didn't I suppress you last time?"

"Fart! That's because I'm preparing a powerful spell! ”

"Can you two be quiet?" Finally, Principal Duris Devonte, who couldn't bear it anymore, opened her mouth to interrupt the endless bickering between the two.

She is the only headmistress of Hogwarts to date, and not only that, but she was also the director of St. Mungo's Hospital for Magical Injuries and Injuries, and is quite a good witch.

"When did William and Gryffindor's residency become so good?" After a brief silence in the principal's office, Principal Devonte asked, somewhat confused.

"I don't know, Devonte, that's what I'm curious about." Dumbledore's eyes flickered, and he didn't know what he was thinking.

"Can't you observe what's going on inside the Room of Requirement, Dumbledore?" Principal Duper asked.

"Of course not, Armando. Don't you know that it's the room that Ravenclaw left behind? Even the headmaster could not spy on the private space that the founders of the college had kept. Before Dumbledore could reply, Headmaster Black replied with disdain.

"As you know, Armando, the founders of Hogwarts have always wanted to put their educational philosophy into practice, and in fact they have left many of their mark on this castle.

One such place is the Room of Requirement, designed by Rowena Ravenclaw herself, and like the Slytherin Chamber, it is the private home of the Big Four.

As far as I know, every inch of the walls of these rooms is enchanted with the magic of shielding monitoring, and there is no way to use this alchemical artifact to monitor it. Dumbledore patiently explained to Headmaster Dupert.

"Is there really a secret room? I thought it was just an absurd legend. Headmaster Duppet asked Dumbledore, who was the previous Headmaster of Hogwarts before Dumbledore and knew very little about these secrets.

"Of course, the great Slytherin of course left such a room, and only those students who fully matched the qualities required by Slytherin would be selected to enter the magical chamber, which probably contained the legacy of Slytherin."

Phineas Black's portrait explains to the Headmasters about the Chamber of Secrets, as he was the Head of Slytherin House and knows more about the secrets of Slytherin than any other portrait.

"It's not hard to understand that an idiot like you who doesn't meet the Slytherin admissions criteria at all doesn't know that the Chamber of Secrets exists."

"If you're so Slytherin-ready, why didn't you find the location of that chamber, Blake?" Principal Dippert shot back sharply.

"You say it again?!"

"Well, it's normal that the Chamber of Secrets is hard to find as a Slytherin setup before leaving Hogwarts.

As you know, for thousands of years, countless headmasters and historians have tried to find this hidden room in the castle, but none of them have succeeded. Dumbledore's words interrupted the argument.

"And, I suspect now, that this attack is very similar to what happened to you at the time, Dippet."

"You mean?" Headmaster Dippet immediately understood what Dumbledore meant.

"Yes, don't you think it's like that accident forty-nine years ago? In a place we don't know yet, the Chamber of Secrets has probably been opened by someone. With that, Dumbledore's gaze turned to the portrait of Headmaster Phineas.

"Phineas, I need you to do me a favor, if I'm not mistaken, you still have this idle portrait in the ancestral home of the Black family at Twelve Grimmauld Place.

If I could, I would like to transfer this portrait of yours to the Room of Request, so that I can also get a general idea of what is going on inside that room. ”

"You don't have to spy on William like that, Dumbledore. Does he have no influence on your plans, or are you suspecting that William opened the secret room? ”

Hearing Dumbledore's plan, Headmaster Devant said to Dumbledore with some dissatisfaction, she was born in the wise Ravenclaw like William, and it is inevitable that she will have this kind of closeness to a very Ravenclaw junior like William.

"But now the Chamber of Secrets has been opened, Devant. As Headmaster of Hogwarts, I need to ensure the safety of my students as much as possible, and the tragedy of forty-nine years ago is enough. Dumbledore's words made Headmaster Davint shut his mouth.

"The Portrait of the Headmaster is in the service of the current Headmaster, Dumbledore. I can't and can't argue with that. Hearing that Dumbledore wanted to use himself, Phineas replied calmly.

"But I'm curious about how you know where William will get in, with so many rooms in the Room of Requirement?"

"It's not hard to judge, after all, he's a Ravenclaw who likes to do research, isn't he?"
