This is what Ravenclaw looks like.

"This is, ah, this face, I have a slight impression of it, not as good-looking as Professor Black."

After making an evaluation of Professor Nina, Professor Binns looked at Andrew and made an evaluation.

'Thank you for looking up to me, Professor. '

Andrew didn't want to say anything - he was inferior to Professor Lockhart, not to mention Sirius, who is currently the most handsome in the school.

"This is classmate Taylor."

Sirius added carefully - in the past year, he was the person who communicated with Professor Binns the most.

"Taylor? Ah, yes, the guy who slept in the History of Magic class."

Let's not mention this now, professor?

The scene was even a little awkward for a while, but fortunately a flying head broke the deadlock - followed by a bunch of Hogwarts regular ghosts and ghosts who occasionally came to visit.

After all, Hogwarts is the cradle of wizards - most of the ghosts have come here to take classes, have been branded with traces of magical significance, and can visit after death.

"Professor Binns!"

The ghost who squeezed in didn't even see Professor McGonagall, "Are you being excluded?"

Andrew found that the professor's expression was a little stiff - but he wisely chose to ignore it.

"Just going out for a vacation, you are?"

"I am, by the way, I was a student about three hundred years ago."

The ghost who squeezed in thought for a while, and then saw Professor McGonagall - I don't know if it was an illusion, Andrew felt that its pearl-like luster weakened a little.

"I was a student five hundred years ago!"

"...Eight hundred..."

...

Andrew just felt a headache listening to a long list of numbers - he thought he was very wise twenty minutes ago, but the boomerang hit too fast.

"Just going out for a few years, if necessary, I will visit you, it's a mess."

"Sorry, professor, mainly because Hogwarts is open today, we came here to join in the fun..."

"If you have time, why not tell me what strange places have happened in recent years. Important things."

...

Another chattering, but this time it was more orderly, at least the ghosts came one by one.

‘Just hearing about these places makes me want to take risks…’

For ghosts, strange places are definitely worth taking risks, but after thinking for a while, Andrew knew that it was impossible for him to go there—he had to study!

“There are also Muggle places, Bermuda—yes, that’s it, wizards have gradually started to go there to deal with the messy magical relics!”

Professor Nina was obviously very happy to hear this, and during the ghosts’ brief break, she even provided a place that sounded like an adventure.

But what she got in return was silence.

The ghosts looked at each other, stopped, and stared at Nina.

She immediately realized her mistake—ghosts can only go to places they have been to before they died, because there are traces of magic in those places.

As an anti-dark magic professor, she should have realized this—but the last-minute study made her not so proficient.

"I'm sorry."

"It was just an accident. It's okay, ma'am. The living and the dead are never the same. There's no way to solve this problem. It's a problem without an answer - just like you and your friends can't attend each other's funerals."

But, if it's a ghost...

Andrew habitually thought of the answer, and then understood what the professor meant - when you understand, you are no longer alive.     "Well, enough secrets of death have been said, and enough people have come. If we don't go to Diagon Alley, I'm afraid it will be dawn."

Professor Binns shook his head, as if he didn't care. "I have to go. I'll write if there's anything. Professor McGonagall - by the way, thank you for your preparations, Mr. Taylor."

The old professor waved his hand, "I'll go out and pay attention. If there's anything worth adventuring, I'll invite you in the summer - don't you Gryffindors like this the most?"

"That's it, see you next time!"

Professor Binns nodded, and the figure carrying the bag flew out of the room directly, disappearing in the blink of an eye.

The messy ghosts followed and disappeared quickly, leaving only Nick, who was almost headless. He gave Andrew a thumbs up, then waved and said goodbye to Professor McGonagall, and chased after him.

‘You Gryffindors? ’

Andrew was stunned for a moment. He couldn’t help but feel a little ashamed of his lazy days in the History of Magic.

But not much. The professor even remembered the wrong college. How could he take all the blame on himself!

“Leave as soon as he said, Professor Binns’ temper.”

Professor McGonagall shook her head, “Andrew, seal Professor Binns’ room.”

“Yes, professor.”

Andrew agreed and began to cast a spell. After sealing, unless the professor came back himself, anyone who wanted to open it would have to go through complicated procedures.

The room guarded by the castle’s protective magic was so big that even Peeves couldn’t enter. Just for this reason, Andrew was sure that Peeves must have unsolved secrets.

“Let’s leave too,” Professor McGonagall nodded gently. “There are classes tomorrow, so we should rest early.”

After Andrew finished casting the spell inside and came out, Professor McGonagall gently tapped the door of the room - under the watchful eyes of two ordinary professors, a dean and a student cast a spell, and the conditions for sealing the magic were met. From today on, this room will be out of use until Professor Binns returns or is expelled.

"Let's go, it's getting late."

Professor McGonagall left first - young professors may not be so obedient, and her pressure is not only on students.

"Huh..."

Professor Nina breathed a sigh of relief, "I almost made a serious mistake."

"Professor Binns knows," Andrew shook his head, "It doesn't matter, the newcomers will be forgiven."

"I hope so, let's go back too."

...

The three people were going to different places, and they separated after walking a little distance.

When Andrew climbed the stairs and returned to the lounge, there was no one at the door of the lounge - there was no doubt that the freshmen had all gone back.

'Start answering the questions. '

He smiled and prepared to open the door, but a figure appeared on the other side.

"I've been looking at the stars for a long time. I'm afraid I'll be the first in astronomy this semester."

Hal's face was a little curious and tired.

"By the way, I've been hiding outside for at least two hours, Taylor. Just for this, I can get some information about some issues that don't involve your office!"

"I'm overthinking. No."

Andrew shook his head quickly, then took out a note from his pocket and read out the answer.

"Come on, I was the first one to open the door in the morning - even if I didn't solve it, I would use an owl to ask people."

He looked at Hal, without any mercy.
