This is what Ravenclaw looks like.

"Professor..."

When Andrew ran to the office breathlessly, Professor McGonagall was grading homework.

It can be seen that it was the fifth-year homework - because there were enough, and Professor McGonagall's expression was not very friendly when grading.

When Andrew stood still, the professor raised his head from the thick paper and pushed the homework aside.

"What happened, Taylor, why are you so anxious?"

Professor McGonagall glanced at Andrew and asked curiously - in her impression, Taylor has always been the kind of person who is not in a hurry.

"We seem to have found something extraordinary. I suspect it is... something left by Slytherin in the castle."

"Slytherin?"

Professor McGonagall laughed suddenly, as if she heard a joke, but soon her expression became serious, "Today is not April Fool's Day, Taylor, are you sure?"

"My Transfiguration can't deal with that magic. It stands to reason that I can forcibly remove the magic locks of ordinary wizards, and we found the Slytherin emblem."

Andrew said with some confidence - this evidence is enough.

"You can't handle it? Let's go... Let's go and see. It's surprising that Albus didn't turn the castle upside down..."

The professor stood up and left the pile of homework without any nostalgia. Andrew even felt that Professor McGonagall was relieved - isn't it true that this year's fifth grade is so weak?

——

"In other words, someone reported it first, and then you surrounded the women's toilet, and found something wrong after clearing it out and searching it?"

Professor McGonagall, who had heard about the discovery of that thing on the way here, began to look serious, "It sounds like someone deliberately led you in... No, it could also be that he originally intended to ruin your reputation, or found something but didn't dare to say it directly?"

The professor made several guesses in a row, but got no results - because Andrew only provided vague clues.

"But I know why Albus didn't find it... He can't find it here..."

The professor laughed, and then walked quickly into the crowd - people seemed to want to slip in, but Percy blocked them at the door. As for the unlucky Nazarov, he was nowhere to be seen at the moment. I think he regretted getting involved.

"Professor!"

Percy shouted in surprise, and the crowd suddenly became silent.

People couldn't help but look back, and then they all stood up straight.

Before Professor McGonagall came over, the students had already made way for the passage. The professor passed by with his lips pursed, but Percy nodded to him when he passed by. Andrew followed behind, communicating with Percy with his eyes and nods, and followed in.

Sure enough, Nazarov was pacing back and forth inside, muttering something in his mouth - if nothing unexpected happened, he should be scolding Andrew.

"Professor McGonagall."

When he looked up and saw Professor McGonagall, Nazarov immediately stepped forward to complain, but when he saw Andrew behind him, he had to roll his eyes fiercely.

"Thank you for your hard work, Lorenzo," the professor nodded, "Where is that thing, Taylor?"

"Here, Professor."

The bean sprouts squeaked under Andrew's step. He took out his wand to remove his Transfiguration and pointed out the problematic water pipe to Professor McGonagall.

"Water pipe?"

Professor McGonagall was stunned, "Taylor, the castle's pipes were far from being built when they were renovated..."

Although the name of Slytherin can indeed intimidate people, this kind of thing should not be put on the pipes - for example, let the experts not look at the microwave-specific bottom of the bowl, but look at the glaze and gloss.

‘But the goods below are genuine, but this can’t be said…’

Andrew could only make a surprised expression, and Professor McGonagall casually took out her wand, and then…

“Something is wrong, Taylor, something is wrong…Go call Albus over, he is at school today, tell Albus that there is indeed a possibility that Slytherin left here.”

Professor McGonagall’s face suddenly became serious, and she quickly gave an instruction.

‘Is it really something that the professor can’t handle? ’

Andrew thought while running towards the door. As for Nazarov next to him, he couldn’t help but cover his mouth at this moment—Slytherin’s things? Oh my God!

——

Dumbledore was quickly invited by Andrew—when Andrew informed him that he had found Slytherin’s things, Dumbledore still had the mind to joke with Andrew, but when Andrew repeated that this was something that Professor McGonagall had confirmed, the headmaster became energetic.

“Albus.”

“Here?”

Dumbledore walked over quickly, observed casually, and then pulled out his wand.

"Sure enough..."

Dumbledore sighed, "Part of the school's authority... the power of the protection system, if this badge is correct, it should be something left by Slytherin, at least related to Slytherin."

"How to open it, Albus?"

"It will take a while, Minerva... about, five days?"

Dumbledore got Professor McGonagall's gaze.

"Okay, three days will be enough... I'm also curious about what's inside."

Dumbledore didn't have the expression of being caught being lazy, which made Andrew admire him very much - I'll write it later... Forget it, don't mention things that are helpful to go to the astronomy tower.

"Student Taylor, come over..."

Dumbledore called Andrew over, "Please describe what happened again. I'm curious about the person at the beginning."

Just be curious...

Andrew has all the drafts and details done.

…

"Well, I can't see anything...what do you think, Taylor-san."

"I suspect it has something to do with what happened at the beginning of school...it's impossible to suddenly reveal the existence of a place like this..."

Andrew hesitated a little and started framing.

"It's true... If it was a backdoor that was installed later, someone must have been involved at the time to do it... And if you try to restart the secret now... do you think it's a prank, or someone framed you, or maybe it's revenge?"

Professor McGonagall's eyes were extremely serious at the moment. She looked at Andrew and nodded - he handled it well. If he broke in and was caught again, there would be no explanation.

"I'm going to ask if you see the person Andrew mentioned in the portrait... If not, then the trap is certain. Lorenzo, come with me."

Professor McGonagall called Nazarov away, firstly to tell him what secrets should not be leaked, and secondly, because the subsequent school opening incident was not suitable for him to listen to.

"Professor Dumbledore," Andrew walked over quickly while Dumbledore was looking at the entrance after Professor McGonagall left, "I think we may have only paid attention to Scabbers when school started. I want to ask the rest of the people who got off the bus. ...Especially the lower grades...I suspect they are bewitched or controlled..."

"…No Veritaserum, Tyler…just talk, just asking - you'll be using Transfiguration to detect those controlling spells, right?"

"Well, I read about it last year..."

Dumbledore hesitated for a moment and nodded, "Go ahead."
