Witcher at Hogwarts

Ethan took out his wand and tapped it lightly on the parchment. "I solemnly swear that I have done nothing good." Ethan said softly.

Thin lines of ink, as thin as a spider web, immediately spread from the place where the wand touched. These lines merged with each other, crossed, criss-crossed, and extended to every corner of the parchment.

The ink on the top of the parchment came together to form several large, curved characters.

Messrs. Moony, Wormtail, Padfoot and Prongs, purveyors of magical mischief makers, proudly present the Marauder's Map.

At this time, criss-crossing ink stains had covered the entire parchment, and a detailed and complete map of Hogwarts was presented in front of Ethan.

The most eye-catching thing is the small ink dots that are constantly moving on the map. Under each ink dot, there is a name written in very small characters.

Ethan saw many familiar names on the map, Harry and Ron were wandering in the courtyard, and Dumbledore was in his office.

George and Fred were sitting in the auditorium, and a group of students gathered around them, probably the Weasley brothers selling Gwent cards.

Hermione was motionless in her dormitory, probably resting.

Luna, on the other hand, was in the Forbidden Forest, probably going to see the little unicorn again.

Ethan focused on observing the traces of Peter Pettigrew on the map, but couldn't find it. He started looking for Lupin's name again, but still couldn't find it.

Even the name of Sirius Black was not discovered by Ethan.

After a brief period of doubt, Ethan figured out that the makers of this map were Lupine, Black, Peter and James.

These four makers used some special methods to hide their names on this map, so that only when they themselves hold the map can the names of several other people be displayed.

So when Lupine got the map back, he discovered the anomaly that there was Peter Pettigrew on the map.

Ethan took out his wand and tapped it lightly on the map. He chanted a spell and a purple light disappeared into the map.

As the purple light entered, the ink on the entire map suddenly became messy.

The moving ink dots and the lines that make up the walls of Hogwarts have also become chaotic.

The next moment, the entire map became quiet again. It has returned to its previous appearance, and the entire map has even become more detailed.

Peter Pettigrew's name appeared in Ron's dormitory, and Remus Lupin's name appeared in his office.

Sirius Black's name also appeared on the edge of the Black Lake. I don't know what he was doing there.

Ethan cracked the Marauder's Map's highest authority. After all, it was a thing created by the Marauder Four when they were students. It was not difficult to destroy it.

Ethan even discovered that under the highest authority, even the Room of Requirement appeared on the map. At this time, there was even a student named Gunter Odim in the Room of Requirement.

Ethan's attention to this name was quickly drawn to Lupin's movements, and the map showed him walking towards his office.

Ethan covered the Marauder's Map with a book and waited for Lupine to knock on his door.

Not long after, there was a knock on the door of Ethan's office, and then Lupine opened the door and walked in.

Lupine was still wearing the same tattered suit he had worn on the train, but he looked much better.

It was probably because the food at Hogwarts was good and allowed him to eat several solid meals.

Because werewolves are contagious, people bitten by werewolves will also turn into werewolves, so it is very difficult for werewolves to find a job in society.

This has resulted in Lu Ping having to rely on doing odd jobs to make ends meet.

"Please sit down! Professor Lupin, you have been here at Hogwarts for so many days and we haven't even had a good talk!" Ethan said with a smile.

Lupine sat on the chair opposite Ethan with some embarrassment, and he spoke hesitantly.

"Professor Ethan, the reason I came here is to meet your teaching assistant," Lupine said hesitantly to Ethan.

He heard from others about the recent weird behavior of the assistant coach brought by Ethan, which gave him a terrible idea.

Now he came to Ethan's office to confirm his idea.

He now couldn't figure out which side Ethan belonged to, and even suspected that Ethan was an undercover agent sent by Voldemort.

"My teaching assistant is on campus, I'll call him back right away," Ethan said.

While waiting for Sirius Black, the two looked at each other, and the atmosphere was a bit awkward.

"By the way, Professor Lupine, I want to ask you some questions." Ethan said to Lupine.

"Just ask," Lupine replied quickly.

"Through investigation, I learned that you were once good friends with Peter Pettigrew, Sirius Black, and Harry's father, James Potter. You also created an organization called the Marauders?"

"Yes." At this point, Lupine's eyes flashed with pain, and Ethan's words reminded him of the time when the four of them were in school.

Now that the Marauders have fallen apart, James and Peter are dead, and it was Sirius Black who caused their deaths.

"Oh? This is strange." A strange smile appeared on Ethan's face.

"I haven't received a strange map brought by a student. That map can show all the secret passages in Hogwarts and the names of everyone in Hogwarts."

Lupine raised his head in surprise when he heard Ethan's words. He knew that Ethan was talking about the Marauder's Map. He didn't expect that the map he made during his student days would actually fall into Ethan's hands.

Lupine said nothing, waiting for Ethan to say the next thing.

"That map is very useful. It can help me catch those naughty students running around, but there seems to be something wrong with that map. It shows the name of a person who has died long ago, Peter Pettigrew."

Lupine's body trembled suddenly, and he stared at Ethan's face in disbelief, "That map is never wrong -" Lupine's voice was trembling.

"Professor Ethan, can you show me that map?" Lupine requested, his forehead full of sweat.

"Of course, no problem." With that, Ethan handed the Marauder's Map under the book to Lupin.

Lupine grabbed the map, and after confirming that it was indeed the Marauder's Map he had made, he eagerly took out his wand.

"I solemnly swear that I have done nothing wrong." Lu Ping said hastily.

The map changed quickly, and then Lupine hurriedly searched the map and quickly found the name of Peter Pettigrew.

"Oh my God!" Lupine sighed and collapsed on the chair.

Many ideas kept popping up in his mind. These ideas had actually appeared in his mind before, but because there was no evidence, even he found them absurd.

Now that I have the support of this Marauder's Map, those previously absurd ideas have become increasingly clear.

An idea that had only occurred in his mind for a moment now filled his mind again.
