Hogwarts: My name is the Unforgivable Curse

"Eh? What's wrong?"

Myrtle and the fat monk were both stunned. Then when the fat monk saw Myrtle standing still, he took the initiative to float to her side and stood still. Then he closed his eyes with a curious look on his face and held the hand. Avatar of the Wand.

"Don't move, wait a moment, please..."

Avada's voice actually trembled a little, and she even took out her wand, ignoring the surprised looks of the people around her, and pointed it at the illusory bodies of Myrtle and the Fat Monk unceremoniously.

His previous research on mental power was mainly focused on human beings, and he did not have a deep understanding of other creatures such as ghosts, so when he took Harry to the abandoned bathroom, he didn't see any problems. And it wasn't until she saw Myrtle standing with other ghosts just now that Avada felt a little bit of a sense of dissonance in her spiritual power through comparison...

And in the current situation, this sense of dissonance may mean a huge problem!

"……found it!"

His face suddenly turned pale - in contrast with the fat monk, he finally discovered the source of the sense of disobedience in Myrtle.

Her memory structure has been changed a little bit.

An extremely tiny bit, maybe only a few milliseconds of memory, seems so insignificant in the huge memory of decades. It is simply smaller than a drop in the ocean, and even more inconspicuous than the plus or minus sign that has been hidden from Sophon. …

What can a memory of just a few milliseconds reveal?

In other words, who would deliberately change a ghost's memory for a few milliseconds? !

"Myrtle, can you come out with me?"

Avada suddenly opened her eyes again, and her face suddenly relaxed a lot. It was as if the tension and trembling just now had never happened: "I think I have something to talk to you about alone. It's about the cause of your death. No. It’s too suitable to say in public and private…”

"The cause of my death? Don't you already know?"

Myrtle followed Avada who had already started to walk out with a puzzled look on her face: "And what's not to say about the cause of my death? That was the only unique thing in my ordinary ten years - Dying inexplicably in the bathroom! Who else could do that besides me?"

"..."

While Myrtle was bluffing, the two of them had already left the bustling auditorium and stood in the corridor outside the auditorium. The noisy sound hummed through the cracks in the door and walls in the quiet corridor, as if from another world. Only then did Avada pull out her wand and point it at Myrtle, her voice slow and low: "Don't move."

"What...what happened?"

Myrtle was startled when she saw the wand. She breathed a sigh of relief after remembering that she was a ghost and that there were very few magics that could work on her, but she still shrank her head nervously.

"There seems to be something wrong with your memory... Yes, that's it, don't move..."

Avada carefully extended his mental power, touched the abnormality in Myrtle's mental power, and then began to slowly correct the abnormality. Although it was only a few milliseconds, It still took Avada a long time to smooth out her memory and restore it to its most natural state...

"Ok?"

Myrtle blinked in confusion: "You've been holding the wand here for a long time, but I don't feel any change in my memory?"

"That's because the amount that was changed was so small."

Avada slowly put away her wand, stared at Myrtle closely and asked, "Now recall it again, how did you die?"

"Um?"

Myrtle frowned and thought for a while before slowly replying: "At that time, I was hiding alone in the bathroom crying, and then suddenly died..."

"Wait, did I tell you last time that I felt dizzy? Sorry, I seem to have remembered it wrong."

"Then before you died...did you see anything special?"

Avada's palms were covered in cold sweat at some point, but this did not prevent him from holding the wand tightly again.

"Well, when you said that, I just remembered that there seems to be something quite special. It seems to be..."

"A pair of huge eyes?"

"..."

Avada was silent for a while, then let out a long sigh:

"Oh shit."

The next second, he ran away!

Go straight to that abandoned bathroom! !

"who is it?"

"Diary? Pure-blood family? Or something else? But how do they know someone will come to explore the secret room on the first day of school?!"

"Hiding the entrance to the secret room, modifying Myrtle's memory, and creating ridiculous attacks to confuse the public..."

"Who is it?!"

Avada felt that her mind was almost overwhelmed by an inexplicable sense of fear. He ran as hard as he could, as if there was a rushing flood behind him... But when he roughly pushed the door open and his body fell into the abandoned bathroom, he realized that he couldn't run -

The little snake symbol that originally looked normal to the magic senses finally showed an extremely complex and sophisticated structure from the perspective of the soul. And beneath those heavy structures, there seems to be a mysterious space hidden... but that's not the point.

The point is, those parts of the structure that are directly connected to the little snake symbol, that is, the magic that opens the secret room, surprisingly have a trace of human modification! !

"I should have thought of it earlier..."

Avada squatted down weakly and pressed her forehead with one hand: "Since Salazar Slytherin is suspected of inheriting the research results of the Peverell brothers, he also has the talent to write Parseltongue into his soul inheritance. The ability to go down, then if he wanted to construct an absolutely secret space, how could he not use this skill?!"

"The opening conditions for the entrance to the Chamber of Secrets have been modified, so Harry's Parselmouth was not responded to at that time...but it was just the first day of school at that time!"

"what is going on……"

He stood blankly by the sink for a long time, and finally shook his head vigorously: "No matter what, the most important thing right now is to crack the magic at the entrance to the secret room as soon as possible, and eliminate all hidden dangers as quickly as possible!"

"I wonder if the magic of this hidden space is similar to the Loyalty Curse. I have to contact Dumbledore. Hell, if only I could find out the problem before he leaves..."

"Do you want to tell Snape? Although Dumbledore said that he would try his best to protect the safety of students, he also said that Snape can only be trusted at critical times... Why is this?"

He rubbed his temples and walked out of the bathroom slowly.

It is foreseeable that in the future, intelligence-enhancing potions and uplifting potions will once again become his staple food - he must do his best to refer to the structure of the resurrection stone and the entrance to the secret chamber, analyze and learn soul-related magic. And this means that he has to spend a lot of time soaking in the women's bathroom, which is obviously not something suitable to do during the day...

"How come after sealing Voldemort, things didn't go away at all..."

Cursing, he turned out of the bathroom and prepared to return to the auditorium to relax for the last time. Then……

Then he saw Argus Filch. and Mrs. Norris next to him.

They are now standing motionless in the middle of the corridor, their bodies still maintaining the posture of taking a step, as stiff as two sculptures. And their eyes were still wide open, staring straight ahead...
