The four of them stood at the door of the library, surrounded by people.

George rubbed his ears and guessed maliciously, "She didn't crumple her book because I crumpled it, but because I spoke ill of Filch!" ”

All four of them gave a lewd smirk.

Rumor has it that Mrs. Pince and Filch are not on an ordinary relationship.

Fred proposed, "We can't stay in the library, let's go to the Gryffindor common room and study the map of the living spots, shall we?" ”

The four of them are still working on Hogwarts maps to be sold.

A few people wanted to copy the map of the living spots, but this thing was much more difficult than they imagined, at least not at their age.

As for the construction plan of Hogwarts Castle that Dumbledore had suggested, William also went to the library to look at it.

The book was divided into seven volumes, each of which had several thousand pages.

William suspected that Dumbledore was simply asking him to find a pastime, and then there would be no time to break the school rules.

But is that a human pastime?

It's a lifetime series.

William was not prepared to study architecture and civil engineering...... In his previous life, he majored in civil engineering.

Persuade people to build and civilize, and the sky will thunder and split.

Cedric glanced around and whispered, "We can go to the Room of Requirement, and by the way, take a look at the Lowe, there is no one there." ”

William nodded.

"Wait...... "The twin brothers looked confused, "There's a room for requirement, what is that?" ”

Standing on the eighth floor of the castle opposite the tapestry of the troll battering Silly Barnabas, William walked around three times when a very smooth door appeared on the wall.

When they walked in, the inside had completely changed.

To be exact, this place was literally demolished into a garbage dump by Luwei, and many items were torn to shreds.

Fred looked at the house and wondered, "It's weird, we escaped Filch here, George, do you remember?" ”

"Yes, it was just a broom cabinet ...... that time"

The two soon became excited, and discovering the secrets of Hogwarts was their greatest pleasure.

George and Fred's eyes were drawn to Louwe.

George walked around excitedly a few times, and said dissatisfiedly: "You actually raised a three-headed dog here, and you still didn't tell us?" ”

"No, it was raised by Hagrid."

William recounted the events of last night.

"Charlie knows about this kind of place, and he doesn't tell us, we are his own brother!" Fred complained loudly.

"So, when you were in Tibet last night, you didn't see who attacked Snape's medicine pantry?" George sat on a cabinet with a thoughtful expression on his face.

"Could it be Professor Tywin? When you went upstairs, you saw him sneaking downstairs......"

Fred continued, "Indeed, don't forget, William has seen Professor Tywin and Snape clash in the hospital!" ”

"But we don't have proof, and it's ......," Cedric shrugged.

"There's no need for Professor Tywin to attack Professor Snape's medicine pantry, if it's just pure revenge, it's less like a professor's approach than a ......"

His gaze was on George and Fred.

Fred casually threw the doll that Hagrid had given to Lou Wei at Cedric, but the latter laughed and grabbed him.

Cedric's tentacles felt wet, and he looked down to see that the doll, which had been almost torn and broken, had a large puddle of unidentified liquid on its chest.

Cedric hurriedly threw it away, and wiped it towards William's robe, which was quickly dodged by William.

Several people burst into laughter.

Cedric had a bitter face, so he had to pinch his wand and use "a clear spring like water" to wash his arm.

Cedric said as he cleaned up, "I think that since the man attacked once, he might attack a second time, as long as it ......"

"As long as we crack the secret of the map of the living spot and keep an eye on that hut, we can catch him!" George pulled out the tattered piece of parchment from his robe.

At this moment, an exclamation came.

Fred was teasing Lu Wei with a small dried fish, but was bitten on his right hand by Lu Wei's head in the middle.

Fred fell to the ground, and Lowe lay on top of him and tore at him.

He begged for help: "Quick, who will come and save me, how to make this guy loose." ”

William said loudly: "Music, Lou Wei likes music, and he will fall asleep when he hears music." ”

Fred immediately whistled.

The three dogheads loosened their mouths at the same time, tilted their heads, and stared at Fred's lips suspiciously, as if they were looking at two shiny sausages.

Lowe is an unusual three-headed dog who loves music, almost like Dumbledore.

Its weakness is music, and every time it hears beautiful music, it falls asleep.

But among the many pieces of music, whistles are an exception, and Lowe is particularly sensitive to whistles, not only does he not sleep, but he is also very excited.

Lu Wei rushed forward, and the three dogs' hair licked like crazy.

Fred is forcibly kissed by a three-headed dog.

It took a long time for everyone to separate the two sides. Fred snorted a few times, covered his mouth, and did not speak, his lips had turned into a sausage mouth.

"Alright," George said with a smile on his face, "let's continue working on our map." ”

The four of them stared at the map, their expressions elusive.

This map is simply love-hate at the same time.

It displays a map of Hogwarts and gives you real-time status of each staircase. On top of that, it pinpoints everyone's location, even Dumbledore.

It's simply the strongest weapon for night tours.

William is going to copy a set of lite copies of this magical map and sell it to other little wizards.

But the problem is that this map is not completely cracked by four people, it needs a secret order in order to work properly.

To put it simply, this map has a secret order, and until you know the secret and unlock it completely, you're just a normal player.

Want to use a map? Simple, in addition to praising the four people who made the map, you have to complete a large number of orders issued by the map!

Even if the prank is completed, the map can be used for a limited time, in the beginning, there were twenty-four hours, and as the number of uses increases, it is now only one hour at a time.

This is also a big reason why the twin brothers have not been on a night tour lately.

To put it bluntly, without cracking the secret order, you are just playing the experience server, and you can't fully grasp the map. If you want to use the map, you have to keep playing pranks!

It's not completely impossible to get the secret order, and the dumbest and easiest way is to complete thousands of pranks according to the requirements of the map, and the map will show the secret order to make you a real player.

So it's a system of pranks, a system that lures you into breaking the school rules, and it's also a bad taste for the people who make the map.

"I know a new way to do it, and it might work." William said.

"The secret order is revealed!" He took his wand and touched the map lightly.

It was a mantra I had heard from Professor Flitwick, and the Dean swore it would work!

But nothing happened.

A moment later, as if an invisible hand was writing on the parchment, handwriting appeared on the smooth surface of the map.

Mr. Moonface greeted Professor Flitwick and told Mr. Stark, "Don't bother thinking about it any more, we've thought of all the spells you can think of.

William smiled awkwardly.

But the map didn't stop there, and new text appeared below the first paragraph.

Mr. Pointed Fork agrees with Mr. Moonface, and would like to add that I admire Mr. Stark, but because he failed the challenge, the next time he uses the map, it will be reduced by five minutes.

“……”

But there's still ...... down there. Mr. Bigfoot expressed surprise: Mr. Weasley has been playing fewer pranks lately, is there any difficulty that I can call the shots and make up those five minutes?

Mr. Wormtail greets Mr. Diggory, good boy, don't mess with this bad boy, good.

Soon the handwriting was gone.
