Hogwarts from another world

In the History of Magic classroom, there seemed to be a brief silence between the three people.

Neville Longbottom looked down at the ground, as if there was something on the ground that attracted him; Hermione Granger sat there quietly, folding her hands on her lap; as for Matthew Wakefield, he seemed I can't really keep myself up.

"We have to do something," Neville finally said.

"I don't understand." Matthew shrugged: "What do you mean?"

"This is the fourth attack. It is actually the third time, but Neville mistakenly thought that Malfoy's attack was also an attack." Neville said solemnly: "Various circumstances have shown that Hogwarts is not safe now. It can even be said to be very dangerous.”

"Professor Grindelwald's threat has become ineffective against the murderer lurking inside Hogwarts; at least judging from Justin's disappearance, his behavior can be said to be almost unscrupulous. We all Their lives are under threat.”

"But the teachers at Hogwarts don't care about this at all. They will only cover up the truth in vain until they can no longer suppress it."

Neville said a series of impassioned words:

"So we must save ourselves. We must use our own power to find the culprit of this series of attacks and bring him out."

"Please allow me to interrupt, Neville." Matthew said softly: "Don't forget that the culprit once knocked down Miss Maria Adams, a seventh-year Slytherin, around Halloween. The three are just three first-year students, even if we find him out, they will not be his opponents."

Matthew's words were earnest and his voice sounded convincing.

Neville frowned, obviously he hadn't thought of this yet.

"At least we can go find the teacher." Hermione on the side suddenly took over: "If we find the real murderer, we will go to the teacher as soon as possible. At least I don't think Professor Flitwick will just sit idly by."

"Yes." Neville nodded quickly: "Neither does Professor Sinistra."

Matthew suddenly looked embarrassed: "Well, I think Professor Slughorn probably, maybe, probably won't just sit back and watch."

"That's okay," Neville waved his fist in victory.

Matthew felt that he had to pour some cold water on these two friends.

"Even so," he said softly, "We don't have any clue, do we?"

"Of course I have no clue." Neville immediately lowered his head, with a slightly ashamed expression on his face: "To be honest, I'm not stupid, but my brain is not smart."

Then, he looked at Hermione and Matthew expectantly: "But I know that Hermione and Matthew are much smarter than me. You must have a clue and a way. Please help me, right?"

"" Matthew didn't know how to respond.

But Hermione on the other side had already spoken: "Yes, I have already had suspicions."

"Who is it?" Neville asked excitedly.

"I told Matthew once before, but he didn't believe me at that time." Hermione glanced at Matthew sideways, and then continued:

"When Weasley was attacked, almost all the blood on his body was sucked by something; and Professor Flitwick told me that there was a unicorn in the Forbidden Forest on the second Saturday of school and on Halloween Eve. Their blood was drained so much that the school finally decided to temporarily move all unicorns from Hogwarts to Austria."

"I have checked the literature related to vampires. Many vampires have the habit of sucking the blood of powerful magical animals, and the blood of unicorns itself has magical uses. Weasley's appearance after being attacked is also similar to that of encountering vampires. Those Muggles are almost identical."

"You mean, there is a vampire in the Hogwarts castle now." Neville looked very frightened, and he couldn't help but shudder.

"That's right." Hermione nodded with certainty: "And, it is our Transfiguration teacher, Professor Trocca."

"Professor Troca" Neville's expression looked slightly dull: "How could that be?"

"Do you still remember the common sense about vampires that Professor Rosier introduced in the first Defense Against the Dark Arts class? They look like Muggles and wizards, but they are pale and cannot be exposed to sunlight." Hermione spoke at a fast pace Extremely fast:

"Then think about Professor Trocca's usual behavior."

"That's it." Neville Longbottom suddenly realized: "No wonder I always think Professor Troca is weird."

"Wait a minute, wait a minute," Matthew said helplessly: "Have you forgotten one thing? There are more than just vampires that can suck blood. What's more, there is no evidence that Professor Trocca must be a retired vampire. Ten Thousand Steps said, even if he is really a vampire, there is no evidence that he must have done these things."

Matthew paused and continued to explain: "Professor Trocca is a teacher at Hogwarts, teacher."

"Matthew, you are too naive." Hermione looked at Matthew seriously and said rudely: "You always think that all teachers are saints, but all the evidence now shows that Professor Trocca has The most serious suspicion”

Suddenly being judged as "naive", Matthew was speechless for a while.

"When Weasley was attacked, he was the first to appear on the scene. This is what Neville told me." Hermione continued:

"That time in the Potions classroom, it was said that he was one of the first teachers to appear on the scene; and at the dinner party before Halloween, when Professor Kettleburn burst into the auditorium, I paid special attention to the guest of honor seat. He was not in the auditorium at the time."

"There is no doubt that Professor Trocca is too suspicious"

"Very well." Neville Longbottom seemed to have made up his mind: "Then from today onwards, we will quietly track Professor Trocca until he reveals his flaws."

Matthew felt that if he didn't say something, things would develop in a slightly worse direction.

"Actually," Matthew cleared his throat and said with a serious face, "I think there is another person who is more suspicious than Professor Trocca."

"Who is it?" Hermione and Neville asked in unison.

"Our Vice-Chancellor, Professor Rozier"
