This is what Ravenclaw looks like.

Until Andrew became familiar with all the documents efficiently, he could not find any records about firecrackers.

However, this thing is different from a mirror. Since you can't find it, just ask - he is originally focused on learning at this stage.

"Professor, can you excuse me?"

Andrew put down what he was doing, stood up and stood in front of Professor McGonagall's desk, and asked in a low voice while Professor McGonagall signed an official document.

"What's wrong? Do you have any doubts?"

"I wanted to find the purchase records of those firecrackers - the colorful firecrackers used for Christmas, but I couldn't find them."

"Those firecrackers?"

Professor McGonagall raised her head from the documents and stared at Andrew, "Is there anything wrong with them?"

"It's perfect - I'm going to see where those firecrackers are made. They're amazing, almost like perfect crafts."

Andrew's tone was quite serious, "I don't know if I have an illusion, but I always feel that the higher-ups have used very advanced transformation techniques to hide several powerful spells.

"What about?"

"The first is the advanced transformation technique that can transform living things into dead objects..."

Andrew briefly stated his guess. He had been tortured by this little thing these days, and he really wanted to hear the opinions of professionals.

"wrong."

A smile appeared on Professor McGonagall's face, "Only transfiguration."

"Only transfiguration?"

Andrew exclaimed - not only him, but Percy also had an expression of disbelief on his face.

"Let living creatures deform, change their body shape, make magic spells deform, break spells deform, smoke deform, even the packaging deforms?"

Andrew muttered quickly that he could not imagine such a thing at all - his understanding of Transfiguration had only just established an outline, and this was completely inconsistent with the principles of Transfiguration!

"That's almost it," Professor McGonagall nodded. "You still lack their overall transformation and unspelling bonuses, but you can still get excellent ones."

Wait…

Andrew finally realized something was wrong - this transfiguration technique contained gold, could it be Professor McGonagall? But it's impossible. With the current workload, Professor McGonagall can't wait to hire a few more assistants. Where will he have the free time to make firecrackers?

"It's Dumbledore."

Professor McGonagall said matter-of-factly, "Professors are all decorating the auditorium, and the principal is no exception."

Oh, that’s it, I understand—that’s weird!

I can’t understand it at all!

It's too inconsistent to connect Dumbledore and making firecrackers! As a principal, shouldn't he be strategizing in the office, thinking about the future of the entire school, and working for the present of the school?

He should maintain good communication with people in other schools, communicate with the Ministry of Magic, provide employment guidance for students, urge professors to work hard, balance conflicts among students, and arrange manpower to handle the school's hardware measures and material supplies. !

But as soon as this idea emerged, Andrew couldn't help but start to cover the principal's tasks - No, why does the person I describe look more and more like the person in front of me?

After thinking about the official documents he had handled during this period, Andrew seemed to understand something at once.

Replies to letters from exchange students from outside magic schools, processing purchase orders for canteen food, campus greenhouses, tables and chairs, protective cushions, funding application documents from professors, official letters from the Ministry of Magic...

This information was added up, and Andrew now believed very much what Professor McGonagall said - she arranged for Dumbledore to make those firecrackers.

The hidden headmaster of Hogwarts, the actual controller of the castle...

For some reason, Andrew suddenly remembered a completely inappropriate classic scene.

"You will regret it..."

"I am xx!"

Shaking his head, Andrew threw this thing that should never be imitated out of his mind. He was still young and had no plans to report to Azkaban - writing this out was no longer a problem that the Astronomy Tower could solve.

"It's good to be interested, but your basic skills are still a bit weak, Mr. Taylor. But I think Dumbledore will be very happy that his works are noticed. Well, you can rest today, Weasley, and so are you. ——It’s time for you to go back and review. You have to pay attention to your studies this year.”

————

Even after leaving Professor McGonagall's office, Andrew did not dare to mention Dumbledore being caught making firecrackers. Percy obviously didn't have the courage either.

The conversation between the two quickly turned to the mirror.

"What will the mirror be used for?"

"I can't guess, it can't be used by fortune tellers, right?"

Andrew shook his head. He no longer had any desire for the mirror, but was just a little curious.

"It can't be in that secret passage - it has been completely destroyed by Professor McGonagall."

"What secret passage?"

"It's the place where students were not allowed to approach before," Percy looked at Andrew with a puzzled look. "Someone saw Hagrid pulling out a big dog from the castle. They thought that all the traps had been dismantled, so they were ready to take risks. The professor deducted a lot of points for catching him.”

Percy looked matter-of-fact.

Although you deliberately didn't mention the house, I guess it must be a Gryffindor student.

However, there is no need to point this out clearly. Andrew smiled and was about to change the topic, but he heard a small argument coming from somewhere.

"Shh..."

He gestured and motioned to Percy.

"Um…"

Percy lowered his voice.

"There is indeed movement."

He walked quickly in the direction of the noise, making Andrew's eyes widen.

"No, what are you doing?"

He lowered his voice and shouted - not for help, but to let you know what happened. Why are you so rough?

This is a school, not a wilderness in the wilderness. No one is killing anyone here. A dispute here means that the two of them could communicate. The most likely thing is that they are friends. If the student is in a lower grade, I will never talk to you again. This is the best thing in the world!

"I'm a prefect and I have to see what's going on."

Percy responded in a low voice, then walked quickly to the door, unscrewing the door without even taking his wand.

"ah?"

He made a sound of surprise.

Andrew walked up quickly - preparing for a fight and forcing Percy to run away.

They can't be a couple... This matter is really worth calling out, and then beating the prefects.

But what he found when he got closer was that there was no one.

There was no one in the room.

"I clearly heard the argument just now - but why is this the only one here?"

Percy pointed to the innermost part of the room, where a mirror they had just said goodbye to stood on the wall, and the room was empty.
