Chapter 170 Professor Change Crisis and Excuse
The fun and the trouble were greater than Andrew had imagined.

The History of Magic class was over, so he had no choice but to take his schoolbag to the laboratory to study his new ideas and optimize the most feasible ones at the same time.

But when he was in full swing of the experiment, recording the fifth failed method on the parchment and preparing to turn the page, he noticed that the pendulum clock on the other table began to swing - in order to prevent interference, the visitor could only notify in this way and hope that the experimenter would have time to see it.

"Who is it..."

Andrew took out his wand, cast a spell to open the door from the inside, and then he became serious.

"Good morning, Professor. My hourglass didn't remind me--"

He glanced out of the corner of his eye and saw that the timer was still working.

"It's not time yet, Taylor, but there's something I need to know right now."

???

What happened? Why is the professor so anxious?
"Professor Binns, Professor Binns has asked for leave..."

Professor McGonagall pursed her lips, looking serious as if she had seen the twins blow up the toilet and appear in front of everyone with a toilet seat.

"Professor Binns? Asking for leave?"

Andrew was also dumbfounded, and was in a state of confusion - didn't he add 20 points to their college? Why did he suddenly ask for leave?
"How long will it take, Professor?"

Andrew tried to calm himself - it was just a request for leave, a small matter, it was just a daily chat.

"One year."

"One year?"

Andrew opened his mouth wide, “Year?”

"Yes, Nian."

"You're kidding, Professor."

How can you take leave based on the year? Others say that annual leave is a year's vacation, but this is a year-based vacation, a whole year!
"I'd rather Professor Binns was joking. What happened in your class? Why did Professor Binns suddenly ask for leave?"

She could endure a week, even a month, but a year? What a joke!
"It's just that Hal Eden, my roommate, asked about Sirius, and then we found out that the professor didn't know the latest information, and then the professor announced the end of the get out of class..."

Andrew tried to recall - to find the details he had missed.

Damn it, he had thought of many troubles, but he had never thought of this problem. It was just a problem. Professor Binns, the most senior professor in Hogwarts who had no relationship with retirement, would have to suspend teaching for a year!
"Just a question?"

Professor McGonagall was also stunned - it was just an ordinary question, and Professor Binns was going to strike for a year?
"You come with me, Taylor, we need to know more."

"Yes, Professor."

-

Andrew had never been to Professor Binns' office - or rather, few people in the entire Hogwarts had been to Professor Binns' office.

There was no way. No normal wizard could fall in love with Professor Binns's courses. His courses had almost no charm at all, and there was nothing difficult to understand about the History of Magic itself - if you could memorize the entire textbook, you would undoubtedly get an O.

"It's no different from a normal office - just no snacks and lots of books..."

Andrew glanced at the layout of Professor Binns' office - bookshelves, parchment, classic sets of quill pens, and then the recliner and fireplace...

The latter is a little weird, but no big deal.

As for Professor Binns himself, he was struggling to pack his luggage before they came in - there is really a limit to what a ghost can carry, and if he packs a little more, he may not be able to carry it.

"Hello, Minerva, has my leave been approved?"

Professor Binns, who controlled the door to open with his mind, asked casually, as if he had only taken two or three days off.

"I'm afraid there are still some problems. For a year, I need to find a substitute professor, but it's not easy to find one. And why does the vacation take so long?" "It's not long, right?"

Professor Binns' eyes were dull for a moment. "I haven't had a vacation in a long, long time. This little time is just enough for me to look around..."

a long time…

Well, if the school legend is true, then it is really very long - compared to the long service period, a year's vacation is a piece of cake.

"But it's still too long. Why did you suddenly think of looking around? Were you offended by that Ravenclaw student?"

"Offended? Are you talking about the boy named Eden? No, not really. It's just that I suddenly discovered that there are too many things buried in history. The treasures guarded by Peeves and Dumbledore's secret treasures in the library are trivial matters. But this incident with Sirius made me want to find those hidden histories."

Ruined…

Andrew looked at Professor McGonagall, and Professor McGonagall looked at Andrew, and they both immediately realized how difficult this task was.

There is a clear division in the existence of ghosts in advanced transfiguration.

A ghost is formed when a wizard refuses to accept the fact of his own death after his death. Most of the reasons for refusing death are obsession, that is, refusing to die because of something.

Professor Binns' original obsession was probably the history of magic, and it is normal that he has now shifted to historical truths related to the history of magic - there is no way to enlighten him. Once a ghost chooses to accept his own death and moves on, he truly welcomes the end and starts a new life.

"Hal, you are such an idiot, you have done so much harm to others!"

Andrew cursed inwardly. He felt that the one who had the greatest impact on Professor Binns was Peeves - after all, he was an existence hated by the entire ghost community, and Peeves hadn't appeared yet...

But there is no doubt that Hal's comments about the change in history were the straw that broke the camel's back.

'We'll try our best to save the situation...'

Andrew took a step forward. "Professor, um, have you finished exploring the secrets of the castle?"

"The secret of the castle?"

"Yes, there are many ghosts in Hogwarts. Do you know their stories, backgrounds, and histories that have been ignored due to time constraints?"

"Interesting existence, indeed... the history of Hogwarts being covered up, those guys even come to hold meetings... In that case, there is really no need to visit various places..."

Professor Binns seemed very interested and he began to compare them on the spot.

"And that won't stop you from teaching the History of Magic and passing on the history, right?"

The most important thing is to make time - even if you have other ideas, delaying it for more than a week will make it easier to recruit new professors.

Anyway, Andrew learned the History of Magic course entirely on his own, so changing professors shouldn't have much of an impact.

"That makes sense, so let's postpone our vacation for now..."

Professor Binns finally gave up his horrible idea of ​​leaving without a second thought, and Andrew was relieved - it would be a good idea to ask all the ghosts in the school. If he delayed for a while, he would even have an excuse to find the entrance to the secret room.

Of course, the most important thing is not to worry about new job postings and the pile of resumes that come with them, as well as creating files for new professors.

"Very good, Taylor, go back to the experiment. I checked and the trend is correct."

Professor McGonagall looked much more relaxed after she came out.

"I have to go on duty, Professor."

"It's okay, take the day off and let Percy come."

"Yes, Professor."

Andrew answered very seriously.
