As soon as Snape saw Maca coming, he knew that it must be for the "mission" that McGonagall had mentioned a few days ago. However, he wasn't interested in anything other than lectures, and never intended to get involved.

"No, you can't."

As far as Snape's unpleasant personality is concerned, Maca's face in the surrounding crowd is already very large. But no matter how big his face is, when it comes to certain issues of principle, he will never buy it.

At this moment, the class bell suddenly passed the ears of the two of them, echoing in the corridor.

"I'm going to start class."

Snape, who had just paused, casually dropped a sentence and continued walking, quickly disappearing into the door of the Defence Against the Dark Arts classroom.

"Bang!"

Maca turned her head and looked at the teachers who were tightly closed, and couldn't help but smile wryly.

"When the time comes, there will still be people from outside the school to participate, and Defence Against the Dark Arts is a popular subject...... Forget it, I'll do it myself! ”

In desperation, Maca shook her head and walked back to Professor Bubaji's office.

Speaking of Ms. Carreddy Bubbaghy, it may have something to do with the fact that she was born in Hufflepuff House, and she is a very gentle and low-key professor on weekdays.

As far as Maca knows, while teaching Muggle Studies, she has also devoted much of her free time to various activities to defend Muggle-related interests, and has kept more than a dozen papers of considerable value in the "Muggle Studies Society".

Of course, none of this is what impresses Maca the most. If you want to say that the most difficult thing about this professor is her tragic sacrifice.

If Maca hadn't appeared in this world, she would have been captured by Voldemort and subjected to brutal torture before being deprived of her life by the Death Eaters in front of the main Death Eaters.

Now, because of Maca, it is clear that all that sad thing will not happen again.

"Tuk-tuk."

At this point in time, Professor Bubaji should be in his office.

"Please come in! The door is not locked—"

To be honest, this is the first time Maca has come to this office, after all, when he was in the third grade, he did not take this subject, which was of no use to him at all.

The office door opened silently, and Maca glanced inside before heading inside.

"Oh, Mr. McLean? You've finally remembered to come and sit with me...... Quick, come here, I just made a pot of milk tea, you must try it! ”

Ms. Bubaji is also in her 40s, but perhaps because of her unprovoked optimism, she looks significantly younger than she actually is.

If you want to talk about the more approachable Hogwarts staff, except for Professor Sprout, who "treats everyone as his own family", she is probably the most approachable.

"Thanks, I'll trouble you."

Maca followed her kindness and sat down at the small table next to her, and slowly looked around while the other party went to the fireplace to pour milk tea.

It has also been said before that almost every professor's office has a unique personal touch. And Professor Bubbaghy, who was keen on Muggle studies, had a lot of Muggle-related objects in her office.

For example, on that neat desk are two small and delicate models of airplanes, and next to the models are several popular science books about airplane construction.

For example, Maca found a lot of promotional material about pigeon racing in a corner of the wall. Although the sport has cooled down in recent years, it is a classic in terms of how popular it once was in the Muggle world.

And another example......

"I'll ...... No way? ”

As he slowly moved his gaze to the bookshelf to the side, a white machine that looked like a brick suddenly attracted all his attention.

“Ga、Game Boy①？ Handheld? ”

Maka's mouth was already crooked.

He never imagined that he would actually see a handheld game console at Hogwarts...... Although he had been mentally prepared before coming to this office, he thought that he would find some "old things" that were closely related to the Muggle world here.

However, the brand-new handheld told him that the preparations he had made were pointless.

"'Game boy'? Oh, you mean that little Muggle machine? Bubaji came to Maca's side with two cups of milk tea left and right, and followed his gaze, "It was sent to me by a pen pal from a Japanese magic institute, and he said it was a good thing......

"It's a pity that she never wrote back to me since, and I never figured out how to start it."

As she spoke, she handed one of the cups of milk tea to Maca, adding:

“…… I've tried it a few times outside and nothing has happened except for a red dot and a line of letters. ”

"Really?" Maca nodded subtly, "This...... It's a pity. ”

While squeezing out a look of regret, Maca suppressed all the complaints that were almost up to her throat. But he actually wanted to tell the other party - if there is no cassette, of course, there is only one line of words!

It seems that at least for the concept of batteries, Bubaji still has some understanding.

He didn't say anything more, just picked up the teacup and took a sip of the milk tea in the cup, the smooth taste spreading out in his mouth, slightly diluting a lot of exclamation marks in his head.

"When the things in front of me are solved, maybe we can go to Asia to have a look, it will be much more interesting than staying here all the time."

Thinking of this, Maca couldn't help but sigh slightly.

"By the way, Professor Bubbaghi, about the mission that Professor McGonagall gave us...... Is there anything you can help with? ”

Putting some of the mess aside for a moment, Maca brought the topic out of here.

"Help...... Miss Bubbaji thought for a moment, "Mr. McLean, I remember you were a Muggle-born wizard, right?" ”

"Yes, that's right!" Maca replied with a bow.

"That's good!" She immediately explained, "I think you should know, I'm a half-blood, and I've been raised in the wizarding world since I was a child. Even though I've done a lot of research into the Muggle world, it's hard to make myself more subjective about the reality of it. ”

Speaking of this, Bubaji spread his hands and asked:

"So, can you help me see if some of my preparations are in trouble? I wonder if they would seem a little strange in the Muggle world. ”

"Of course," said Maca, cheerfully, "please speak!" That's what I'm here for! ”

Seeing that Maca had so readily agreed, Ms. Bubaji immediately thanked her happily, and then walked briskly to a cupboard against the wall not far away.

It didn't take long for her to pull out a rather large roll of parchment from it, and with a brisk stride she came to Maca again.

"You take a look at this first, I'm going to use it as the theme to create a surprise for everyone!" "Actually, it's a research project of my own, and I've been working on it for years...... It's just, seriously, this big guy is so complicated, and there's a lot of stuff I haven't been able to figure out yet. ”

Hearing this, Maca placed the teacup on the small table first, and then reached out to take the three-foot-long roll of parchment.

But when he untied the ribbon tied to the paper scroll and unfolded it, the emotions that had just calmed down once again stirred up a thousand waves.

Today, I'm afraid it's the first time he's had mood swings so often since he regained his emotions!

"This ......," Marka said in a strange tone that could no longer be suppressed, "Professor Bubagi, I think that as long as you continue to persist in your research, you will definitely be at the vanguard of reform in the contemporary wizarding world!" ”

Only now did he realize that he had unconsciously ignored a potential "legend" over the years.

……

Professor Binns was now troubled by the fact that his idea had been politely rejected by Maca, who came in at noon to inquire about it, on the grounds that it was "completely uninspiring."

However, no matter what kind of activities are carried out, what "new ideas" can be tossed out of the discipline of the history of magic?

He floated up and down his office, his translucent body moving back and forth in his desk, and yet he didn't notice it.

The only ghost professor at Hogwarts didn't need an office for a long time, after all, he couldn't touch anything. But because of the elves' diligent cleaning, the place remained the same as it was on the day of his death, and almost nothing had changed.

"Well, the history of magic ...... 'new' ......"

For so many years, the elder Binns had not thought about anything other than to read out the large number of memories contained in his head during class time. It was Professor McGonagall, the Headmaster, who spoke, that he would not have been happy to think about such a thing at all.

Compared to Snape, the ghost professor had less desire for power, but he had no worse temper.

I think he was actually a violent temper when he was alive, and he was a well-known argument at the time of the four founders, and he was a typical high-combat scholar who "drowned you with saliva".

If it weren't for the fact that he had passed so many years by now, he would not have thought of being so conscientious and yet obscure.

"Otherwise, let's take out those old things and make them count......"

Old Binns nodded as if he had suddenly thought of something, turned his head and floated towards the wall on his right, and then plunged into the wall and left.
