After more than twenty minutes, Maca finally ate his breakfast for the day.

"Well, this jam tastes good today." He smeared the slices of bread and smiled at Hermione, "I'm sorry for you." ”

I don't know if it's the relationship between the power of the rule light pillar that Maca had that night, to be honest, the weather today is surprisingly good.

He pulled back the curtains in his office, and the sunlight poured in from outside, drenching the room in a clean, warm pale gold.

Compared to the dry heat of the fireplace, the warmth of the sun always brings a strange beauty.

Suddenly, Maca puffed out her cheeks and asked:

"By the way, what did you say you wanted me to ask you just now? Or does it have to do with Muggle science? ”

"Oh, that's ......"

The girls weren't really coming to him to ask questions, it was mostly just an excuse - at least that's what Hermione thought.

So as soon as she heard Maca mention it, she suddenly remembered this incident.

"It was Professor Bubaji who had a problem," Hermione explained, "she had intended to use the 'steam engine' as the subject of Muggle Studies for this Christmas event, but it was much more difficult than she had imagined, so she didn't get it right until the last day......"

"So you're going to help her?" Maca glanced at Luna a few times, and said with a subtle expression, "You didn't mess up the professor, did you?" ”

When the latter heard this, he immediately raised his hands above her head, and her arms writhed strangely above her head like soaked spaghetti.

"The professor says it can get hot!" Luna mimicked, "Look, I guess that's probably the case - but I remember that Muggle 'machines' weren't available at the school, and I don't think the professor had been able to do that because of his unsuccessful success." ”

"Oh, I see...... You put your hands down first! ”

Maca shook her head with a smile before she said to Hermione, "What do you think?" ”

When Hermione heard this, she couldn't help but shrug her shoulders.

"I don't know......," she said, thinking for a moment, before changing her words, "Well, I mean - I don't understand how Muggle products can't be used in school, and I don't know much about the construction of steam engines, so I can't just give my opinions." ”

"Oh," Maka couldn't help laughing, "your answer is very scientific. ”

With that, he tossed the rest of the bread into his mouth, then patted the crumbs on his hand and stood up.

"Let's go, let's go and have a look."

If you continue to stay here, sooner or later the conversation will be affected by what happened last night. In order to avoid everyone being in a dilemma of whether to say or not, Maca simply followed the incident to relax, so he said vaguely and walked to the door.

As he walked to the door, he just glanced back at his desk, where there were still a lot of materials on it! But soon, he took his eyes back and stopped looking.

"Come on!"

Beckoning Hermione and Luna to leave together, the three of them spoke casually, and soon arrived at the Muggle Studies professor's office where Kerry Dee Bubbaji was.

In fact, as far as the two girls were concerned, Maca naturally knew about it for a long time. After all, when Professor Bubaji took out the blueprints, he was the first person to see them.

However, when Maca saw the brass-colored metal monster in the other party's office, he only wondered if he had misremembered something.

"This is ...... 'steam engine'?"

To be honest, it was a real "monster".

The huge barrel was placed crookedly in the middle, surrounded by copper pipes that zigzagged and swirled, and a dozen ropes that did not know what to do with them extended from the side of the many copper pillars, hanging limply one by one.

Behind the mess, a wheel larger than the barrel in the middle sits there, giving the impression of a big fat beetle carrying a wheel larger than itself.

"Yes, this is the steam engine!"

Professor Bubaji put down the tools at hand, first rubbing the back of her hand against her forehead, and then greeted her with a happy face, despite the fact that her face was already covered with all kinds of oil.

"Look at it, isn't it great?" She said happily, and then said with some regret, "Unfortunately, I haven't been able to get it up and running." ”

Maca looked at this very "steampunk" big guy, and felt a little weird inexplicably - even Merlin didn't know how this professor made something with a specific design to make it look like this!

"yes, it's great."

"Thank you, thank you......" Bubaji nodded repeatedly, then turned to say, "Oh, you guys are ...... Well, did little Luna invite you to help? ”

"Yes! I looked for Hermione, and then Hermione went with me for Maca...... I'd love to be able to see it steam before the holidays! ”

Luna replied as she raised her hand and shook her arm. And it wasn't until then that Maca knew that this somewhat stupid action was not original to Luna!

For Lady Bubaji was even more cheerful than Luna in mimicking the steam as it rose up.

"I don't think I can stand it anymore......" Hermione said softly as she stood beside Maca, lowering her voice, "Maca, can you find a way to get them to stop doing this?" ”

But Maca spread her hands and said:

"You know what? If it weren't for the fact that everyone should go back to enjoy the Christmas holidays tonight, I'm actually more worried that it will catch on at Hogwarts! ”

Hermione shuddered when she heard him say this.

It can't be helped, this action is a little too magical.

"Ahem...... Anyway, let's take a look at what's going on! ”

Ignoring Luna and Bubji's "steam parody show", Maca walked briskly past the pair of living treasures and came to the big guy that Bubaji called a "steam engine".

Speaking of which, Maca's height is indeed not tall, but it is actually not short. But now standing next to the machine, it was like a Gringotts goblin walking up to some adult.

"Tom-tom—"

He tapped his fingers at the big barrel in the middle—fortunately, at least it was empty.

Then Maca circled around the big guy again, making sure that at least the brass pipes were firmly attached at both ends.

According to the original design drawings spread out on the side, except for the layout of the pipes, which is very curious, there seems to be nothing wrong with the others.

But when he turned around again, he found a key problem.

"Professor Bubagi, where's its boiler?" Maca pointed back at the thing and asked, "Where did you heat it up?" ”

When Bubaji saw him ask, he was interested again.

Seeing that she no longer went to shake her arms with Luna, she hurriedly came to Maca's side, pointed to the design drawing, and said:

"That boiler is just to heat the barrels, but you know, the Muggles used to burn coal to the point that all of London was blackened – so I thought, since we're wizards, why not just replace it with a more environmentally friendly magical flame?"

At this point, she seemed to think that explaining by mouth was not enough, and suddenly reached out and pulled a drawstring.

And with her tugging, a lid suddenly unscrewed automatically, revealing a small copper pipe connected to a huge barrel.

"Look, according to the blueprints, the first step is to put some water in here first—" Bubaji pointed to Maca, then pulled out his wand and pointed at the nozzle, "Clear water like a spring." ”

After pouring some water into it, Bubaji tugged on the drawstring again, causing the lid to be screwed back on.

"Then it's time to burn the fire......"

Maca saw that she wanted to show herself on the spot, and hurriedly blocked her from continuing to do it.

Although he didn't know the specific design requirements of this thing, he still remembered that it could explode, and the explosion was not small.

"Professor Bubhaji, this 'steam engine' will explode, I think we should ...... it gradually"

Before Maca could finish her sentence, she quickly stopped. Because he inadvertently noticed that when Bubaji was about to light the fire, Luna quickly hid behind her desk.

He was stunned for a moment, and then said hesitantly: "Could it be ...... You've already blown it up once? ”

Bubaji looked at Maca and smiled a particularly bright smile. But before she could speak, Luna, who was hiding behind the desk, poked her head out and whispered:

"I've blown it up five times—"

"Professor Bubagi," Maca said earnestly, immediately turning, "I sincerely suggest that the manufacture of the steam engine be halted for a moment!" I'm afraid you're going to be taken to Madam Pomfrey before you can make your things......"

Luna then added:

"The professor has been there three times—"

"Luna, come here!" Maca immediately shouted at her, "Don't come here until Professor Bubaji can make something exactly like the one on this drawing." ”

When she got back here, Maca said to Hermione:

"I can't do anything about this 'steam engine', I think we should go back!"

Before the words fell, he pulled the two girls and hurriedly ran out, but there was Bubaji's slightly excited voice behind him-

"Hey! Don't go! I don't think it's going to blow up this time, trust me! Don't go......"

Maca still remembered that this Lady Bubaji was a very gentle witch, but she did not expect that she would become so excited and fanatical when she was doing her favorite research.

It seems that when Muggles talk about the word "wizard", they always think of the image of "an old witch with a poison stirring and a sinister face", which is really not unreasonable.

After leaving Bubaji's office, Maca and her two daughters went on a stroll around the activities they hadn't been to, and time flew by.
