"Professor Snape, there doesn't seem to be any school rule at Hogwarts that forbids professors from appearing in the corridor at night!"

However, as soon as Professor Quirrell finished his words, he immediately felt that Snape's hand on his neck had become even tighter.

In an instant, Professor Quirrell, who was already having difficulty breathing, almost couldn't breathe, and his face turned red.

Snape spoke slowly, "Professor Quirrell, you seem to be more than just in the corridors of Hogwarts, right? What are you doing in the tower? Let me think, what's in the tower? Oh, yes, it's the Pen of Acceptance and the Book of Admission!"

At this point, Snape's expression became noticeably colder. He put his eyes close to Quirrell's, stared into his eyes quietly, and asked meaningfully: "Professor Quirrell, tell me, what are you looking for?"

But at this moment, Qi Luo could hardly breathe, let alone speak.

Seeing this, Snape loosened his hand slightly, and Quirrell immediately began to breathe heavily.

After a long while, Quirrell, who was gradually recovering, looked at Snape with resentment and said slowly: "Professor Snape, I don't know what you are talking about?! I just think the moonlight tonight is pretty good, and I want to go to a higher place to admire the moon!"

Seeing Quirrell's denial, Snape was not surprised. He looked Quirrell up and down and said sternly: "Professor Quirrell, I hope you don't forget who you are!"

After hearing Snape's words, for some reason, Quirrell was silent for a moment, and then suddenly laughed out loud.

At the same time, Harry and Ron, wearing invisibility cloaks, happened to walk to the corner of the corridor not far from Quirrell and Snape, and the sudden laughter in the corridor immediately scared the two of them.

The two of them walked curiously towards the direction where the laughter came from, but happened to see Snape pinching Quirrell's neck and pointing his wand at him.

At the same time, Quirrell sneered and said:

"Professor Snape, have you forgotten your own identity? Do you really think that you are a loyal Potions professor at Hogwarts? Former Death Eater, Mr. Severus Snape?"

Of course Harry now knew what Death Eaters were. When he suddenly heard this explosive news and discovered that a Death Eater was right next to him, he lost his mind in an instant and couldn't help but take a step back.

But Harry forgot that at this moment, he and Ron were wearing their own invisibility cloaks.

Harry suddenly took a step back, and Ron naturally did not keep up with Harry's pace, which made half of Harry's body exposed behind the invisibility cloak.

And at this moment, right under Harry's feet, a loud cat's cry suddenly came: "Meow!"

The sudden cry startled Harry and Ron. They looked down and saw that it was Filch's cat, Mrs. Norris!

At the same time, Harry and Ron discovered that half of Harry's body was exposed outside the invisibility cloak, and Harry quickly retracted his body.

But at this moment, in the originally silent Hogwarts Castle, the sudden cat's meow was too eye-catching.

Almost at the same time, Snape first let go of the hand that was pinching Quirrell's neck. Then, the two looked at each other and pretended nothing had happened, and walked towards Harry and Ron.

Seeing this, Ron and Harry subconsciously wanted to walk back.

But at this moment, Filch's voice was heard again on the way Harry and Ron came.

"Haha, I found you! Damn little mice!"

In a short period of time, Harry and Ron seemed to be stuck in a dilemma.

Seeing the people on both sides getting closer and closer to them, Harry and Ron looked at each other and had to slowly retreat towards the wall. The two of them pressed against the wall, not daring to breathe.

Soon, Filch, Quirrell and Snape met in front of Harry and Ron.

When the lantern in Filch's hand shone on Quirrell and Snape, Filch's face changed instantly.

The original intention was to arrest students who violated curfew, but ended up arresting two professors!

When Quirrell and Snape saw Filch, they both breathed a sigh of relief. After all, if their conversation was heard by a Hogwarts student, it would probably cause a lot of trouble.

Seeing Filch standing there with a lantern in hand, Snape had no choice but to ask, "What happened?"

Hearing Snape's question, Filch said in a panic: "Professors, this is what happened. Some students broke curfew and ran away secretly. I'm looking for them!"

Hearing Filch's words, Snape frowned and said:

"Oh, really? Who is it?"

Filch shook his head awkwardly, and replied, "Sorry, professors, I didn't see them."

After hearing Filch's answer, Quirrell asked curiously:

"If you didn't see them, how do you know that there were students running out?"

Then, Filch took out a paper crane from his pocket, put it in his palm, and held it in front of Quirrell and Snape, saying at the same time: "Because, I found this in the corridor. I didn't find it during my first patrol tonight, but when I came back, it fell in the corridor. So, it must have been dropped by a student who violated curfew and sneaked out!"

Seeing this, Quirrell nodded without comment.

But then, Quirrell and Filch were surprised to find that Snape was behaving strangely.

Snape was staring at the paper cranes in Filch's hand, motionless, as if he was standing there.

Filch, who was standing opposite Snape, felt as if he was dazzled, because he saw that Professor Snape's eyes seemed to turn red in an instant! After a long while, Quirrell and Filch heard Snape say in a hoarse voice: "Filch, where did you find this paper crane?"

Although he was a little curious, Filch still spoke, "It's in the corridor on the sixth floor of the castle, Professor Snape."

Hearing Filch's answer, Snape nodded, then he suddenly reached out and took the paper crane from Filch's hand, and walked away quickly, saying, "I'll go and take a look!"

After hearing what Snape said, Filch naturally could not say anything more, and Quirrell was even more eager for Snape to leave quickly, otherwise, Quirrell was really afraid that after Filch left, Snape would pinch his neck and question him again.

In a short period of time, the corridor that was once bustling with activity became deserted.
