Chapter 171 I solemnly swear that I am up to no good

After waiting in the Great Hall for a while, Andy and the others saw Fred strutting back in.

Seeing this, Andy whispered to Hermione, "See? When you have a secret on you, you have to be bold and relaxed like Fred so that you don't draw suspicion."

"Hmph!" Hermione grunted lightly in dissatisfaction.

Who would be as skilful as a few of them, if they didn't do bad things all the time?

Fred smiled smugly at Andy, "Dude, we've got the stuff, but we need to find a place where no one is around to show it to you."

George got up, "The castle is full of places like this, let's go."

The four of them found a secluded spot in the castle, and Fred pulled a folded parchment out of his coat pocket.

"What's this?" Hermione asked curiously.

Andy opened the parchment and spread it out on the ground, flipped it back and forth, shook his head and said, "I can't tell."

Fred grinned mischievously, "You can take out your wand and try."

George also looked at Andy with an expectant face.

Andy was instantly wary, "This isn't the product of a joke you guys made, is it?"

"I wish it was made by us."

"But we don't have the technology to do so."

"Andy, try it. You're a future master wizard, so you wouldn't be afraid of a small piece of parchment, would you?"

"Come on! Give it a try."

George and Fred said one sentence each, and then looked at Andy with an expectant face, as if they were waiting to see how Andy would make a fool of himself, with ill will written all over their bodies.

"..."

Andy took out his wand.

"Aparecium!"

Andy touched the parchment lightly with his wand.

After waiting for a moment, nothing happened as a result.

Andy glanced quizzically at George and Fred, and the twins gave a 'please continue' look back.

Andy raised an eyebrow.

"Show your secret, or I'll burn you in a fire."

Andy increased the force and tapped the parchment with his wand.

This approach seemed as if it was a joke, but in reality, it was an application of magic.

Through magic, one communicates one's emotions and thoughts to the other party.

The parchment appeared to change as if an invisible hand was writing on that parchment, and words appeared on the smooth surface of the parchment.

"Mr Moony sends his regards to Mr Andy Collins and asks him to use his brain and not just wave a stick around when things go wrong like a troll."

Andy's expression froze, and Hermione looked dumbfounded.

George and Fred, on the other hand, were all smiles, as if the prank had worked.

The piece of parchment seemed to refuse to stop, and new writing appeared below the first paragraph.

"Mr Prongs agrees with Mr Moony and is willing to add that Mr Andy Collins has a bit of a thin stick."

"Mr Prongs is willing to express surprise: what can such a thin stick do?"

"Mr Wormtail sends his regards to Mr Andy Collins, and hopes that he goes back to his studies and fills his empty brain."

Andy wasn't at all angry at being insulted, instead, he asked curiously, "How did that work?"

George said smugly, "Andy, do you think that's all this parchment is good for?"

"Watch this!"

Fred took out his wand and pointed it at the parchment, whispering under his breath, "I solemnly swear that I am up to no good."

As Fred recited the words, a new change appeared on the parchment.

A cloud of ink melted away in the centre of the parchment, and a criss-crossing line began to appear, and between the lines, a variety of names also appeared on a small dot.   

"This is a map of Hogwarts?"

Andy was surprised, "These names ... This map can show the location of everyone in the castle?"

Fred said, "Look, this is the Headmaster's office. Professor Dumbledore is ... walking through the office right now."

George said, "He does that all the time."

"This is Snape's office, he should be boiling a potion right now."

"This is Professor McGonagall ..."

"Filch is on the third floor of the castle."

"We're here."

"This is the castle's secret passage. The secret passage of the one-eyed witch that we told you about earlier was discovered on this map."

After listening to George and Fred's introduction, Andy's entire being is stunned.

Making a map of Hogwarts was nothing, what was difficult was, making the map display the real-time location of everyone in the castle.

This was not something that could be done with ordinary magic.

Especially, it also showed Dumbledore's name on it.

From this, it could be seen that Dumbledore might not be aware of the existence of this map.

"We call it the Marauder's Map."

"Andy, it belongs to you now, and we want you to use it properly."

Hearing the twins' words, Andy struggled for a moment and refused, "This map is too precious, I can't ..."

"Don't say that!"

Fred laughed, "This map was found in our first year in Filch's office, where there was a collection of confiscated items."

George said, "We didn't believe that the person who had this map would be caught by Filch."

"After graduation, this map won't be much use."

"So it's about time we passed it on to the next generation."

Andy was silent for a moment and said gratefully, "Thanks."

Hermione was also shocked by the functions of the Marauder's Map, and the young witch was a little disturbed and felt that the map should just be handed over to the professor.

The little witch had a look at Andy, the sentence 'we should hand it over to the professor' didn't come out in the end.

Because Hermione knew very well in her heart that Andy would never be able to hand this map over to the professor, and it was also impossible for her to secretly snitch Andy to the professor.

What's more, there was also a vague sense of unrest and excitement in Hermione's heart. It was as if there was a secret that only she knew and no one else did.

"With this map, I can keep track of Snape's whereabouts." In this way, Andy was more certain about stealing the potion ingredients.

George made a suggestion, "Snape is very cunning, you better clean up the smell on your body before you act."

Fred added, "And remember not to lose your hair."

"And don't fart."

"Better bring gloves."

"And put shoe covers on your shoes."

"And a mask."

The twins made many suggestions, and Andy nodded thoughtfully.

In the second term of his first year, on the night of Quirrell's action, Andy had been caught by Snape while using a Disillusionment Charm to conceal his form, all in the pitch-black corridor.

Andy didn't dare underestimate Snape.

"Once I understand Snape's movements and make preparations, I will act immediately," Andy said.
