The Wind and the Eagle Wings at Hogwarts

"How can I make a 'message' without being destroyed by ordinary students?" Fred turned to ask George.

George shook his head, "I only know that directly carving words on the wall won't work. We can't destroy the castle."

"Yes, Hogwarts Castle is a whole." Scott said, "The magic contained in this castle is too huge, and our magic cannot leave traces of damage on any wall."

Fred asked curiously: "Like the message that appeared on the wall tonight? I noticed that the words were still flashing. What spell did the 'Heir of Slytherin' use?"

"I don't know either."

Scott really didn't know what magic Tom Riddle in the Diary Horcrux used to manipulate Ginny to leave the glowing words on the wall.

He began to talk about his method, "I am going to use a permanent sticking spell to stick the letters on the wall. I happened to have seen this spell in a book and asked Professor Flitwick for advice."

He said: "This approach does not count as destroying the wall, so it will not trigger the magic reaction of the castle."

"Is it that simple?" Fred was a little surprised.

"Simple, but effective." Scott said with a smile, "It's always difficult for people to separate things stuck with the permanent sticking spell."

George nodded in agreement, "It's indeed a good idea. This is how my father glued the magic clock in our house to the wall. It's a pity that we don't know this spell yet, otherwise I will glue Percy's mouth together permanently."

Fred said, "Oh! I doubt Percy knows this spell, he has already stuck the prefect badge firmly on his robe!"

"Okay, you can't do this, otherwise Mrs. Weasley will glue your hands and feet together." Scott said funny.

"Have you thought of anything you might write to offend the heir?" he asked.

Fred raised his hand in a pretentious manner and said, "Slytherin is an old monkey, a big fool?"

"I think you are the idiot." George patted Fred's raised hand, "This will anger all the Slytherins, including Old Bat! How will we determine the target then?"

Fred raised his hand tenaciously and said, "So, the heir of Slytherin is a fool?"

"No." George said with a smile, "It should be written like this - idiot! The descendants of Slytherin are almost extinct, and the last madman of the Gaunt family is in Azkaban!"

"How do you know?" Fred looked at him in surprise.

"Oh! Mom and Dad mentioned it when they were chatting. There is only one lunatic left in the Gaunt family who is imprisoned in Azkaban." George smiled proudly.

Scott said to George: "It's good, but it's not enough. We should attack the other side with what they care about most."

"What do you care about most?" George thought for a moment and his eyes lit up. "Bloodline. Guys who worship Slytherin must care about pure bloodline the most."

Scott showed a weird smile and said slowly: "I think it should be written like this - shocked! The last lunatic of the Gunter family gave birth to an heir with the dementors in Azkaban."

"Wow!"

Both George and Fred were shocked and looked at Scott with novel eyes, their expressions were very sour.

Scott nodded secretly, very satisfied with the essence he learned from the UC Shock Department in his previous life.

He took out another roll of wire and placed it on the table, picked up his wand and cast the simplest transfiguration spell on the wire.

The wire twisted automatically and quickly formed a line of conjoined characters.

[Shock! The last madman of the Gaunt family gave birth to an heir with a dementor in Azkaban. ]

Scott looked at his work, each letter was as big as a palm, and he nodded with satisfaction.

Fred looked at this line of text with bright eyes and sighed exaggeratedly, "Oh! Scott, you are so vicious!"

"Too bad! We actually lost this time!" George touched the non-existent tears on his face.

Scott stood up and said helplessly to the two guys who were busy playing tricks: "Hurry up, we have to take action. When we get out, I will be responsible for sticking this thing on the wall, and you will be responsible for keeping watch for me."

"no problem."

George and Fred also stood up immediately and saluted him nondescriptly.

George picked up the Marauder's Map on the table, but his expression changed, "No! When did that old guy Filch show up there?"

Fred leaned over, "He's motionless there. It seems he wants to stay there and catch the murderer for his cat?"

"Filch? It seems we can only wait."

Scott sat back again and took out a few small mirrors from the deformed lizard skin bag on his waist.

He told the twins: "Fortunately, we still have some preparations to make."

"What is this, a mirror?" Fred picked up a mirror and looked at it, then looked at Scott in confusion.

"This is for the cameras."

Scott reached for the photo camera.

"There's no way we're hiding around there and taking pictures. If we were discovered, the guy probably wouldn't come out."

"What I just wanted to say." Fred said in confusion, "Why use a camera? Can't we just arrest that person?"

Scott looked at George, the more stable of the twins, "I don't recommend doing this, because we might not be able to defeat each other. We just need to get the evidence and leave it to the professors to deal with."

George reached out and patted the somewhat unconvinced Fred, "I agree with Scott."

"Professor? Didn't you say that the 'Heir' appeared fifty years ago? Maybe the Professor can't be trusted either." Fred said this deliberately.

"Dumbledore can't be trusted either?" George patted him again.

"Alright alright."

Fred was still a little regretful that he couldn't catch the murderer himself, but since George agreed with Scott's statement, he could only accept it.

"You haven't said how to do this yet, Scott." He held up the mirror in his hand.

"It's simple."

Scott used transfiguration to make a shell, put the mirror inside and made a simple periscope and handed it to Fred so that he could experience it for himself.

Fred experienced it and immediately became happy, "Oh! Is this Muggle magic?"

Scott was a little surprised. The periscope was not a modern invention. The wizards didn't even know this.

He briefly explained the principle of the periscope, then picked up the Marauder's Map and started looking for the best location to install the camera.

Only after estimating the location and distance, he could start making this device that could take pictures while turning around.

Of course, he didn't plan to stay here from the next day on.

If Tom Riddle acted while they were in class, or waited until night, he might not be able to capture evidence.

So he also needed a device that could allow the camera to take pictures automatically.
