"Bump!"

"It's your turn, George." Fred handed the tool to George, "My hand is about to break."

"This is the first combination?" George took the tool and asked,

Lawrence waved his wand to help the trio renew the protective charm, because the flammable material had to be ground into powder and then mixed, so it was very dangerous to make this thing - for Muggles, of course,

A few weeks ago, they began experimenting with recipes in various proportions, and thanks to the Room of Requirement, a room with complete tools and a test site appeared.

"The two hundred and eighteenth." Lawrence replied precisely, and George carefully grinded the material,

"It's getting more and more powerful." Lawrence scrutinized the toilet splinter at the test site and waved his wand to fix it, "We're in the right direction."

"There's no denying that Muggles do have their merits." Fred said that at first, the three of them were still giggling and playing with materials, but as a result, a small spark came out of the wand, which accidentally caused an explosion, and if Lawrence hadn't put on the protective charm beforehand, maybe the three of them would have been injured at that time.

"Wait, we'll go back to the dorm this time." George proposed, and he carefully checked the pile to see if there were any unground particles.

"Bump!" Another test explosion,

"Not bad." Lawrence waved his wand to block the flying shards,

"Let's go back." Fred took out a map of the living spots and carefully examined his surroundings,

"Harry, what are they doing in the Astronomy Tower?" George said suspiciously,

"Look at the stars, huh?" Fred replied casually,

"They've got an invisibility cloak, so they'll be fine." Lawrence replied.

────────

"So you forgot your invisibility cloak at the top of the tower?" Lawrence looked at poor Harry and Hermione amusedly,

"You're not going to come to us for something like this?" Fred said angrily,

"A dragon! If we have him, we might be a bit of a helper." George said resentfully,

"Oh! That's enough!" Hermione said angrily and sadly, "You're still thinking about this at this time?"

"When?" Lawrence asked, "It's not a big deal."

"Do you want us to scold you?" Fred raised an eyebrow and asked, "I'm so angry that you didn't ask us for such a fun thing."

"That's not fun." Hermione retorted, "According to the Ministry of Magic, it is illegal to raise dragons."

"It's also against school rules to wander around the school at night, Hermione." George said earnestly, "Whatever you mean."

"Oh." Hermione was speechless,

"I'm not going to get that many points back." Harry said dejectedly,

"You're just giving back the points you got from Quidditch." Lawrence said calmly, "But I think you need to explain to your teammates and apologize, you earned the points together."

"I see." Harry got up and left,

"Don't be too frustrated, miss." George said, "You're not earning more than 50 points."

Hermione ignored him and took out her textbook and buried her head in the book, and George shrugged and beckoned Fred to go to class with Lawrence.

────────

After a few weeks, the final exam was approaching, and they finally experimented with a finished product that satisfied all three of them, but they also found a small problem.

"There's a danger to 'that thing,' and we don't want anyone to get hurt when we play a prank." Fred took advantage of Professor McGonagall's turn and said that they were now referring to the explosives as "that thing" for fear of being heard.

"We can't expect students to cast a protective charm before going to the bathroom." George whispered,

"So we're going to wait until no one uses the toilet." Lawrence said,

"When is there a time other than at night when no students will use the toilet?" Fred asked, "During class?"

"Some people will skip class, Fred." George said,

"Actually, there was a time during the day, and people weren't in the toilet at that time." Lawrence said,

"When?" Fred asked eagerly, and Lawrence was about to speak, when Professor McGonagall turned around and swept over the three of them with a sharp eye, so frightened that they hurriedly sat down in their seats,

"Next week is the final exam," Professor McGonagall continued, ignoring the wails of the students below, "As your Gryffindor Dean, I must say that I will be disappointed if someone fails the final exam."

She stopped her gaze on Fred and George and said, "Class."

"She must be talking about me and George." Fred complained,

"She should just be a little sad, Fred." Lawrence reassured, "You and George could have done better."

"Well, you've managed to make me feel guilty, Lawrence." George said, "Anyway, there should be enough of that thing, so you can help us make up for it in the next few days."

"No problem."

So, for the next few days, they were quietly reviewing their homework, and as soon as the exam was over, Lawrence and the twins hid in the Room of Requirement, where they were experimenting with how long a special fuse could burn.

"Thanks to this rope, it makes it difficult for the flame to be extinguished." Lawrence said lightly,

"Hopefully the plan will go well," said George briskly, "and we'll have to get these things in place before midnight."

"I hope there's plenty of food." Fred glanced around the corner, baskets of small biscuits and creamy beer.

────────

At midnight, they finished packing, and one by one the finished products were neatly wrapped in waterproof paper.

Lawrence picked up the live spot map on the table to assign work,

"George, you're in charge of the toilets on the seventh and eighth floors." Lawrence said, "Fred, you are in charge of the fifth and sixth floors, and the third and fourth floors will be handed over to me, and when they are all put away, we will go back here and meet up and then go to the first and second floors."

He casually swept over a black dot on the second floor of the map, and then he couldn't take his eyes off it.

"What's wrong?" George packed his backpack and put the finished products into it.

"It's fine." Lawrence calmly put away the map and pretended to organize his backpack, and Fred and George left first.

Lawrence pulled out the map, and he watched as the little black dot moved to the third floor, with two lines of cursive writing underneath:

Quirinas. Quirrell

Voldemort

(Note 1, Note 2)

"Same point...... Is it possession?" Lawrence instantly understood, it was like someone lit a lamp to illuminate everything, and the various events that happened this semester also had answers,

He looked in the direction of the headmaster's office, and his eyes swept every corridor, staircase, and classroom, but he couldn't find a small dot representing Dumbledore, he looked back to the third floor, and found three small black dots representing Harry, Ron, and Hermione, and disappeared after stepping into the third floor.

"Damn, how could this be?" Lawrence frowned, "Normally, the Philosopher's Stone level should be able to stop Harry, right?"

He folded the map and put it in his pocket, put his backpack down, tightened his wand, pushed open the door and ran quickly towards the third floor, where he was going to stop the three Harry and Voldemort before they met.

────────

Note 1: When I wrote this, I had three versions in mind.

The first version of the map shows "Tom. Riddle',

The second version shows "Voldemort",

The third version shows both, (Author's note: Damn, it's too long!) Cheat?! Can you imagine three lines of words appearing below a dot? The hallways aren't that wide, man. ）

Uh-huh! The three versions have different plots, and I thought hard about what he should be called now, and then I thought about the second episode, Dobby, the house-elf's answer to Harry after he was free, "Before the Dark Lord changed his name, everyone was called that way." ，

Okay, so I guess the map would show Voldemort, and then I think I would imply that if the second episode of "If it were" on the map, it would be Tom. Riddle

Although he privately referred to himself as Voldemort during his time at school, Dumbledore also mentions in the second episode that "when he appears in front of everyone under the name of Voldemort, no one can associate him with the boy who was once smart and handsome." So I guess I should be fine with this setup...... Probably, right?

If you find any information about Voldemort on the map in the book, please use the book review area to tell me, me, me, me!!

Note 2: The timing of Quirrell's possession is yet to be studied, but it is certain that it was not at the bar, and that Harry had already been possessed the week before they went to the Forbidden Forest Labor Service (the first dead unicorn).

Thanks to the reward from the outer building of Tsing Yi Building, the author and I went to eat in tears.
