"I don't understand why we wake up so early." Fred grumbled, while spreading a thick layer of jam on the bread,

"If we don't practice fortune-telling, divination, or Muggle studies, we can sleep until we wake up today, Lawrence." George took the hot milk from Fred and yawned in agreement.

"Hey, figure it out, you said you wanted to learn how to make Muggle grenades." Lawrence added some sugar to his cereal,

The twins studied possible ways to blow up the toilet, but most of the methods they could think of required the use of a wand, and they learned from Lawrence that some methods were to know what spells the wand had cast.

The rest of the way was either too expensive or too powerful, so Lawrence suggested that there was a kind of bomb called a grenade in the Muggle world, which should meet their need to blow up the toilets.

"You said this kind of stuff is dangerous for Muggles, will Muggle schools teach it?" Fred asked suspiciously,

"Well, I don't know, I only went to Muggle elementary school." Lawrence said ominously,

"Well, we can all learn the Explosion Charm and the Fire Charm in school, I don't think Muggle schools are too much different?" George speculated, (Note 1)

"I'm sorry I overheard your conversation." A girl's voice said, and the three of them turned around to see Gryffindor's newborn, Hermione. Granger

"You can't do that, it's going to hurt Gryffindor." Hermione was not frightened by the sudden gaze of the three, but insisted on her opinion,

"Professor McGonagall's daughter?" Fred asked suspiciously, and Lawrence resisted the urge to laugh, because he felt that it was a bit rude,

"No, at least not the hair." George went on to say that Lawrence hurriedly picked up the Daily Prophet to cover the corners of his mouth that was about to be lost, Professor McGonagall always wore her hair up, and Hermione's fluffy brown hair had no resemblance to Professor McGonagall at all.

"Oh, haven't you read Hogwarts, A History?" Hermione's face flushed, but she continued to insist, "There's ...... in the air here."

"Filled with intense magic, electronic devices and equipment will fail here." Lawrence controlled his expression, put down the newspaper and said,

"It's rare to meet a Gryffindor who has also read Hogwarts, A History." Lawrence said appreciatively, "But I don't think Muggle grenades are instruments or equipment, Miss Granger?"

"Oh, that's enough." Hermione angrily grabbed her bag and hurried to keep up with the Gryffindor freshmen who were about to walk out of the cafeteria, because it had only been a week since they arrived at the school, and the freshmen who were not familiar with the road always acted collectively, so as not to be alone and unable to find their way to class.

"I'm, our young Miss McGonagall." Fred joked, "I have a hunch that we're going to have a hard time in the future? What do you say?"

"I have a hunch that Miss Granger will be even tougher, Fred." George said, "What if the little one calls the old one?"

"Well, I think it's time for us to go to class too." Lawrence carefully folded a page of the newspaper on the progress of the investigation into the July 31 Gringotts robbery, and he had a habit of collecting important stories.

Kerry Di. Professor Bubage was a Muggle fanatic like Mr. Weasley, at least that's what Lawrence thought,

"Look at this! Muggles call this thing a car," Professor Bubaji shouted excitedly, pointing to the picture of the car, "and there's something in the car called the engine."

"Muggles have engines for a lot of things, guys, like an airplane, and Muggles use engines to get airplanes flying." Professor Babuji waved his arms excitedly, "Can you imagine? Guys, Muggles even fly very high with powerful engines, and they claim that they have something called a spaceship, and they use that to land on the moon......

"I regret it, Lawrence." Fred struggled to open his eyelids,

"Is there still a chance to withdraw from the class?" George asked hopefully,

「…… Probably not." Lawrence gave them a heavy blow,

"Do you think he'll know about grenades?" George asked,

"Just ask......" Fred replied by raising his hand and shouting, "Professor Bubagi! Do you know how Muggle grenades are made?"

"Huh? Fred. Weasley, yes?" Professor Bubaji was visibly stunned for a moment, then asked, "Is the grenade made of an engine?"

"Ugh...... Is the engine powerful?" Fred asked uncertainly, looking at Lawrence with a pleading eye, Lawrence tried to put on a poker face, and he was already laughing crazy in his heart,

"Awesome, very powerful, I just said that Muggles can fly to the moon with engines, and it is said that they are planning to fly to Mars recently!"

"Then I think it's made with an engine, right?" Fred replied stiffly, and Lawrence clenched his fists in an effort to keep himself on the poker face,

"It's amazing!" Professor Bubaji shouted happily, "Mr. Fred, then please hand in a report on Engines and Grenades in the next class and share it with everyone."

Fred banged his head on the table several times with a blank face, George patted him sympathetically on the shoulder, and Lawrence, the initiator, was lying on the table, and if he listened carefully, it was not difficult to hear his suppressed laughter,

From their first lesson, they learned that it was impossible to learn how to make grenades with Muggle Studies.

"Lawrence, you're cheating me." No matter how much Fred didn't know about the Muggle world, he reflected that he had been cheated.

"No, why do you think that?" Lawrence said earnestly, taking some beef and baked potatoes from the long table, and laughed all morning, he was hungry, "I really thought Muggle schools would teach these things."

"We can write a report together tonight, and oh my God, it's only the first week of school." George said as he took some chicken sandwiches from the long table.

"Writing a report?" Fred frantically, "Lawrence just needs to check the rules, you have Lawrence to help, who is going to teach me that damn engine and grenade?"

"No, isn't this man here?" Georg Nunu gestured for the entrance to the restaurant, and Hermione followed Professor McGonagall into the dining room, "Oh! No, the little ones really call the old ones."

"Miss Granger, you want to blow up the school toilets?" Professor McGonagall asked, in a dangerous tone,

"Uh, why do you think that?" George asked cautiously, "We haven't done anything bad since school started, Professor."

"I just heard Professor Bubhaji," said Professor McGonagall, "Fred asked a strange question in class, Mr. Rovande, what do you mean?"

"Well, some minor issues with engines and grenades." Lawrence replied awkwardly, he glanced at Hermione, he sweared, he saw the corners of Hermione's mouth twitch as if he wanted to laugh,

"Guess what answer I got when I asked Miss Granger what they were?" Professor McGonagall's dangerous gaze swept over the three,

"We're just curious, Professor." George said,

"Just curious, we haven't done anything yet." Fred added,

"Curiosity is not a sin, Professor." Lawrence argues,

"Oh, of course, but this year, if I find out what's going on in the school toilets." Professor McGonagall sternly said, "I'm going to show you how Muggles make a toilet."

Professor McGonagall left, leaving the dejected trio behind, and Lawrence put down the half-eaten baked potatoes.

"Actually, why do you do that?" Hermione asked seriously, "The professors and prefects are saying that if you don't play pranks, it won't be difficult for Gryffindor to win the House Cup in the past two years."

"A boring pursuit, miss." George replied,

"Oh, we'll all be mindful that the deduction and the bonus are just tied." "It means it's not just our responsibility to not get the Cup," Fred said.

"What we mean by this is that if you really want to win the House Cup, everyone in the House has to work hard for it, not just one person working alone." Lawrence laughs, "Like we do pranks together, sometimes we ask others to help."

"There's something I'd like to ask you for help with right now." Fred said, "About grenades..."

"I'm not going to blow up the toilet for you." Hermione said solemnly with her hands on her chest, her expression exactly the same as that of Professor McGonagall,

「… with the engine's report." Fred said indignantly, "Who knows what the hell this thing is?"

Hermione couldn't help but laugh, and in exchange, the three of them offered to come to them for help if they had any problems in the future, and that next week they would let Gryffindor have a prank-free week in peace.

Note 1: When we were children, we always imagined that in the middle of class, alien monsters invaded the earth, and then the school playground would open up and a robot would appear, and then each teacher would rush into the teacher's office, which had become an operational command post...... Hey? Why look at me with that idiotic look, no one has thought about it?

Well, Fred didn't realize that although he had learned the Explosion Charm and the Fire Charm, he had also learned that the water was like a spring and the restoration was the same, and I think the wizards also had enough spells to prevent fire, water, and earthquakes.

It can be said that the definition of danger is fundamentally different between Muggle root wizards (from the beginning of the third episode it can even be found that the existing wizards are happy to be "caught by Muggles and burned at the stake"), and then, you can't ask a kid who has been studying magic since elementary school and is friends with two super tricksters to have any idea of being close to ordinary people, and Fred was indeed cheated by Lawrence, and George, who misled Fred earlier, was definitely an accomplice.
