Chapter 171 I solemnly swear that I have done no good deeds

After waiting in the auditorium for a while, Andy and others saw Fred walking back in a swaggering manner.

When Andy saw this, he whispered to Hermione: "Did you see it? If you have a secret, you have to be as generous as Fred to avoid arousing suspicion."

"Hmph!" Hermione snorted dissatisfiedly.

If they didn't often do bad things, who would be as skilled as them?

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

George stood up and said, "The castle is full of places like this. Let's go."

The four of them found a hidden location in the castle, and Fred took out a folded piece of parchment from his pocket.

"What is this?" Hermione asked curiously.

Andy opened the parchment and spread it on the ground, looked over it, shook his head and said, "I can't see it."

Fred smiled evilly and said, "You can take out your wand and try it."

George also looked at Andy expectantly.

Andy immediately became alert, "Isn't this a joke product you made?"

"I wish this was what we did."

"But we don't have such technology."

"Andy, give it a try. You are a future magic master. You are not afraid of a small piece of parchment, right?"

"Come on! Let's see."

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

"..."

Andy took out his wand.

"Show your secret!"

Andy touched the parchment lightly with his wand.

After waiting for a while, nothing happened.

Andy glanced at George and Fred in confusion, and the twins responded with a 'please continue' expression.

Andy raised an eyebrow.

"Show your secret or I'll burn you on fire."

Andy pressed harder and tapped the parchment with his wand.

This method may seem like a joke, but in fact it is also an application of magic.

Convey your emotions and thoughts to the other party through magic.

The parchment changed, as if there was an invisible hand writing on the parchment, and writing appeared on the smooth surface of the parchment.

"Mr. Moony greeted Mr. Andy Collins and asked him to use his brain and stop being like a troll who just waved his stick when things happened."

Andy's face froze, and Hermione was also stunned.

George and Fred were all smiles, as if the prank had succeeded.

The parchment seemed unwilling to give up, and new writing appeared under the first paragraph.

"Mr. Prongs agrees with Mr. Moony, and would like to add that Mr. Andy Collins's stick is a bit thin."

"Mr. Padfoot is willing to express surprise: What can such a thin stick be used for?"

"Mr. Wormtail says hello to Mr. Andy Collins. I hope he can study hard when he goes back and fill his empty mind."

Andy was not angry at being insulted, but asked curiously: "How did you do this?"

George said proudly: "Andy, do you think this parchment is only useful?"

"Watch it!"

Fred took out his wand and pointed it at the parchment, and whispered: "I solemnly swear that I have done no good."

As Fred chanted the spell, new changes appeared on the parchment.

A ball of ink spread out in the center of the parchment, and criss-crossing lines began to appear. Between the interlacing lines, various names appeared on small dots.

"Is this a map of Hogwarts?"

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

Fred introduced: "Look, this is the principal's office. Professor Dumbledore is... walking in the office right now."

George responded: "He does it all the time."

"This is Snape's office. He should be brewing the potion right now."

"This is Professor McGonagall..."

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

"We are here."

"This is the secret passage of the castle. The one-eyed witch's secret passage we told you before was discovered from this map."

After listening to George and Fred's introduction, Andy was stunned.

Making a map of Hogwarts is nothing. What is difficult is making the map display the locations of everyone in the castle in real time.

This is not something ordinary magic can do.

In particular, Dumbledore's name is displayed on it.

This shows that Dumbledore may not be aware of the existence of this map.

"We call it the Marauder's Map."

"Andy, it's yours now, and we want you to put it to good use."

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

"Don't say that!"

Fred smiled: "This map was found in Filch's office when we were in first grade. There are many confiscated items there."

George said: "We don't believe that the person who owns this map will be caught by Filch."

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

"So it's time for us to pass it on to the next generation."

Andy was silent for a moment and said gratefully: "Thank you."

Hermione was also shocked by the function of the Marauder's Map. The little witch was a little uneasy. She felt that this map should be handed over to the professor.

The little witch looked at Andy, but she still didn't say the words 'We should give it to the professor'.

Because Hermione knew very well that Andy would never give this map to the professor, and it was impossible for her to secretly report Andy to the professor.

What's more, Hermione also had a vague sense of restless excitement in her heart. It's like there is a secret that only you know and no one else knows.

"With this map, I can keep track of Snape's whereabouts at any time." In this way, Andy would be more confident about stealing potion materials.

George made a suggestion, "Snape is very cunning. You'd better clean up the smell before acting."

Fred added: "Also, don't lose your hair."

"Don't fart either."

"Better wear gloves."

"Wear shoe covers on your shoes, too."

"And masks."

The twins made a lot of suggestions, and Andy nodded thoughtfully.

In the second semester of the first grade, on the night of Quirrell's operation, Andy used the Disguise Charm to hide his figure, and was caught by Snape in the dark corridor.

Andy didn't dare to underestimate Snape.

"When I understand Snape's movements and am ready, I will act immediately." Andy said.
