Harry Potter’s Book of Sin

After more than twenty minutes, Maca finally had his breakfast today.

"Well, this jam tastes good today." As he smeared the bread slices, he smiled at Hermione, "Excuse me, please run this time."

I don't know if it was due to the light beam of the rule that Maca had that night. To be honest, the weather today was surprisingly good.

He opened the curtains in the office, and sunlight poured in from outside, soaking the whole room in a clean and warm pale gold.

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

Suddenly, Maca asked with bulging cheeks:

"By the way, just now did you say you wanted to ask me what questions? Is it related to Muggle science?"

"Oh, it's like this..."

The two girls didn't really come to him to ask questions, they were mostly just excuses-at least that's what Hermione felt.

So when Maca mentioned it, she suddenly recalled the incident.

"Professor Bubaji encountered a difficulty," Hermione explained. "She originally wanted to use the'steam engine' as the subject of Muggle studies for this Christmas event, but it was more difficult to understand than she thought. Many, so I haven’t gotten it right until the last day..."

"So you went to help her?" Maca looked at Luna a few times, with a subtle expression on her face, "Isn't it messing up the professor?"

When the latter heard the words, he immediately raised his hands above her head, and her arms twisted strangely on top of her head like soft spaghetti.

"The professor said it could give off heat!" Luna imitated, "Look, I guess that's the way it is-but I remember that those Muggle'machines' are not available within the school. I think the professor has been Didn't succeed, could that be the reason for this?"

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

Maca shook her head dumbfounded, and then said to Hermione, "What do you think?"

When Hermione heard it, she couldn't help shrugging.

"I don't know..." she said, thinking for a while, and then changed her words, "Well, I mean-I don't understand the principle that Muggle products cannot be used in schools, nor the structure of steam engines. It's not very clear, so I can't express my views and opinions casually."

"Oh," Maca couldn't help laughing. "Your answer is very scientific."

After that, he threw the remaining bread into his mouth, then patted the crumbs on his hands and stood up.

"Go, let's go and see together."

If you continue to stay here, sooner or later, the topic will be affected by what happened last night.In order to prevent everyone from getting into the embarrassment of whether they should be said or not, Maca simply followed the incident to relax, so he said vaguely and walked to the door.

When he walked to the door, he just glanced back at the desk-there are still a lot of materials on the desk right now!But soon, he closed his gaze back and stopped looking.

"come on!"

Greeting Hermione and Luna to leave together, the three of them talked casually, and soon arrived at the office of the Muggle Studies professor where Keridi Bubbaji was.

In fact, Maca had already known what the two girls said.After all, when Professor Bubaji took out the design drawings, he was the first person he saw.

However, when Maca saw the brass-colored metal monster in the other's office, he only felt that he had remembered something wrong.

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

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

The huge drum was placed crookedly in the middle, surrounded by copper pipes surrounded by twists and turns. A dozen or so pull ropes, which did not know what they were doing, stretched out from the copper pillars and slumped weakly.

And behind these messy things, a wheel larger than the barrel in the middle is placed there, and the overall feeling is like a big fat beetle carrying a wheel larger than itself.

"Yes, this is the steam engine!"

Professor Bubbaji put down the tools at hand, she first rubbed her forehead with the back of her hand, and then greeted her with a happily face, no matter if her face was already covered with all kinds of oil.

"Look at it, isn't it great?" She said happily, and then said a little regretfully, "Unfortunately, I haven't gotten it working yet."

Maca looked at this big "steampunk" guy, and felt a little weird inexplicably-I am afraid that Merlin didn't know how the professor made a thing with a specific design drawing into this look!

"Yes, it's really great."

"Thank you, thank you..." Bubbaji nodded his head repeatedly, then turned to say, "Oh, you guys... well, did Little Luna invite you to help?"

"Yeah! I looked for Hermione, and then Hermione and I looked for Maca... I would love to be able to see it as it steams before the holiday!"

While Luna answered like this, she began to raise her hand and shake her arm again.And it wasn't until then that Maca knew that this kind of stupid action was not originally Luna!

Because Ms. Bubbaji actually imitated the scene when steam was rising happily than Luna.

"I don't think I can take it anymore..." Hermione stood beside Maca, lowered her voice and said softly, "Maca, can you think of a way to stop them from doing this?"

But Maca actually spread his hand:

"Do you know? If it weren't for everyone to go back to enjoy the Christmas holiday tonight, I'm actually more worried that it will become popular in Hogwarts!"

When Hermione heard him say this, she suddenly shuddered.

No way, this action is really magical.

"Ahem... Anyway, let's see what's going on first!"

Without going to the "steam imitation show" between Luna and Bubaji, Maca quickly walked past the pair of live treasures and came to this big guy called "steam engine" by Bubaji.

Speaking of it, Maca's height is indeed not high, but it is not short.But now standing next to this machine, it was like a Gringotts goblin approaching an adult.

"Tom Tom——"

He flexed his fingers on the big barrel in the middle-fortunately, at least the inside was indeed empty.

Then Maca turned around the big guy again and confirmed that at least the copper pipe was firmly connected at both ends.

According to the original design drawings just spread out on the side, apart from the strange arrangement of the pipelines, there seems to be nothing wrong with the others.

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

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

Seeing him ask, Bubbaji immediately became interested again.

Seeing that she stopped shaking her arms with Luna, she hurriedly came to Maca's side, pointed to the blueprint and said:

"The function of that boiler is just to heat the barrel, but you know that Muggles used to burn coal so that the whole of London has turned black-so I thought, since we are wizards, why not just use more Instead of environmentally friendly magic flames?"

Speaking of this, she seemed to feel that explanations by her mouth were not enough, and suddenly she stretched out her hand to pull a rope.

And as she tugged like that, a lid was automatically unscrewed, revealing a small copper tube connected to the giant barrel.

"Look, according to the design drawing, the first step is to put some water here—" Bubbaji pointed to Maca, then took out his wand and pointed it at the nozzle, "Clear water is like a spring. "

After pouring some water into it, Bubbaji pulled the drawstring again and twisted the lid back.

"Then it's burning..."

Maca saw that she wanted to demonstrate to herself on the spot, and quickly blocked her from letting her continue.

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

"Professor Bubbaji, this'steam engine' will explode, I think we are still gradual..."

Before Maca finished speaking, she stopped soon.Because he inadvertently discovered that when Bubbaji was about to ignite, Luna quickly hid behind the desk with eyesight.

He was stunned, then hesitated and said: "Could it be that... you have already exploded once?"

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

"It's been bombed five times--"

"Professor Bubbaji," Maca immediately turned his head and said seriously, "I sincerely suggest that the manufacture of steam engines should stop for a while! I am worried that people will be carried to Pangfo before you can make things. Mrs. Lei is there..."

Luna then said again:

"The professor has been there three times -"

"Luna, come here!" Macka immediately yelled to her, "You are not allowed to come here in the future, unless Professor Bubbaji can make something exactly like the drawing."

After she came back here, Maca said to Hermione again:

"I can do nothing about this'steam engine', I think we should go back!"

Before he could finish his words, he took the two girls and ran out in a hurry, but Bubbaji's slightly excited voice came from behind——

"Hey! Don't go! I don't think it will explode this time, you believe me! Don't go..."

Maca still remembers that Ms. Bubbaji was originally a very gentle witch, but unexpectedly she would become so excited and fanatical when she was doing her favorite research.

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

After leaving Bubbaji's office, Maca and the two women went shopping for activities they hadn't been to, and time passed quickly.
