HP Parallel World

"A student in our school suffered a petrification attack. I only learned about this after the Quidditch match ended this morning." Because I did not go to the field outside the castle to watch the game on Sunday, so the fact

After having breakfast, he returned to his office. Principal Keller was using a shorthand quill to process documents in his office and repairing his star telescope.

"The person who came to tell me that a student was attacked in the castle quickly rushed to the school hospital with me. In the school hospital, I also carefully examined the body of the petrified boy who fell.

situation."

There was also no way to restore the boy lying on the hospital bed to normal just by waving a magic wand. Principal Keller was also not sure at the time who had cast what kind of magic to bring the student in front of him back to normal.

It became like this.

"It is confirmed that the student is not dead. This is definitely good enough news. My thought this morning was very simple, that is - no matter how much suspicion and curiosity we have about this attack, as long as the antidote can be prepared,

Then we just need to wait patiently and let the parties involved explain the matter clearly to us in the near future."

Facing the depressed and worried vice principal and others, he believed that how to stabilize the emotions of other students and ensure the normal order of the school was the most important thing. At that time, Principal Keller noticed

It's a small detail that no one else paid attention to.

"Although the victim was petrified, in the final analysis, he was not turned directly into stone, but was just made into a hard state like frozen food. Therefore, the clothes still worn on this boy's body,

It naturally maintains its original state."

Although the petrified boy entered the women's bathroom only after the draft blew open the door, and he was also wearing an invisibility cloak, but because he stayed in the bathroom long enough, everyone in the bathroom was

The aromatic plant smell of the air freshener used inevitably stained the boys' clothes.

"Judging from the smell that lingered on the boy's robe at that time, I can definitely conclude that he stayed in the bathroom for so long, and it was definitely not just to solve a physical problem." I have already lived to this age.

Of course, it is impossible not to experience diarrhea and constipation in your life. Ms. Keller knows very well that even because of these two conditions, you need to stay in the bathroom for a long time. People who stay in the bathroom for a long time

, the smell on his robe will definitely not be stronger than the smell on the petrified boy.

"After noticing the smell on the boy's robe, I immediately asked Krova and asked her if they had carefully searched the corridor where the fallen boy was, as well as several rooms near the corridor.

They had been inspected. And the answer I got at that time was that these rooms had indeed been inspected, but there was nothing noteworthy about them."

"..." At that time, she was facing a student who had an unexpected accident. She felt anxious and extremely shocked, so she didn't pay attention to the smell of the air freshener in the bathroom. Krova did not expect that Keller

The principal's entry point is actually this place.

"Obviously a very exciting game was being held on the field outside the castle, but the boy who was petrified not only did not go to the field to watch the game, but stayed in the bathroom of the castle for such a long time. Faced with such a situation, how could I

Maybe it doesn’t feel weird?”

"After the situation in the school hospital stabilized, Klova quickly investigated who could be confirmed to have not gone to the stadium to watch the game, and who had left the game halfway through the game.

. And facing all these students who were brought in for cross-examination by Krova, I noticed a problem with Winnie."

"I...I?" I just felt that after opening the secret room, I didn't do anything unnecessary in the pipes and the stone room below. Winnie had been riding on the broomstick all the time, and even

His feet had never touched the ground. Therefore, he really didn't understand for a while that there was anything about him that deserved Keller's attention.

"Is the robe you are wearing now the same robe you wore this morning?" Because the students are all wearing uniform black robes, there is no way to judge whether Wei Ni has changed clothes based on the style and color.

, Principal Keller, after getting a positive answer from Winnie, waved him to come to him.

"Look, this is what I care about." After Winnie came to him, he pushed his shoulder with his hand and asked him to turn half a circle. Principal Keller then raised his hand and grabbed the item.

The sleeves of the black robe. "Look, the elbow is obviously covered with algae, isn't it?"

This kind of green algae can be seen everywhere in the damp and sticky pipes. However, although it is a very common thing in the pipes, inside the castle, except for the secret rooms that others cannot enter at all, there is no

This kind of thing doesn't grow anywhere else.

"I have been at Hogwarts for so many years, and I have never seen this kind of thing in the corridor or in any room. And I am sure that even if you go to the greenhouse where you usually have Herbology class, you will

There is no way to find this kind of thing in a greenhouse."

Although more than ten hours have passed since this morning, after all, they live in a very barren secret chamber with no nutrients. Therefore, algae that can take root and grow in such a place must be very tenacious.

Therefore, even if Principal Keller pointed it out at this moment, the algae on Weini's sleeves has not completely lost its freshness.

"According to your answer when the vice-principal asked you whether you saw anything unusual in the castle during the game this morning, I don't understand it at all. Logically speaking, you didn't go there at all.

How on earth did you get this fresh algae on your sleeve when you went to some secret place in the school that was not known to others?"

Compared to now, more than ten hours later, when I first saw the algae stained on the clothes more than ten hours ago, I could tell at a glance how fresh they were. Principal Keller can be sure,

Winnie got away from his friends during the game and went to an unknown place, so he allowed these things to be stained on his clothes.

"You encountered a kidnapping case yesterday. I know about this. After all, petty quarrels between students can be classified as things that young people do when their blood surges and their minds are hot for a while.

However, this kind of thing that is obviously going to ruin someone's future is obviously completely different in nature from the previous violent and impulsive behavior."

Therefore, as the top administrator of the school, he will definitely be concerned about this matter. As long as Keller learns from the vice principal what clues the investigation team found about the kidnappers in the woods, then she will naturally be able to find out everything.

They discovered that the petrified boy lying in the school hospital was completely consistent with the clues that Krova and the others had investigated.

"One person ditched everyone and didn't go to the game, and instead stayed in the bathroom for a long time; while the other guy ditched his friends, also didn't go to the game, and was contaminated with these inexplicable algae. Faced with this

What do you think I would think about the situation?"

As long as you mention the bathroom, you will naturally think of water, and when you think of water, you will naturally think of the drainage system. Principal Keller faced the algae on Wei Ni's clothes. If you still can't think of the gutters and everything in the sewers,

There are all kinds of strange little beings growing up, but they really are not qualified to be a principal.

"So, Madam Principal, you've already checked that bathroom, right?" He didn't even notice that there was such a stain on his clothes. Only then did Wei Ni truly realize that the normally unremarkable person in front of him was

The little old lady actually has very good eyesight.

"Yes, I checked." Faced with Wei Ni's question, she nodded decisively and patted him on the shoulder, indicating that he could go back to his partner. Ms. Keller continued: "

Krova told me that she had checked the corridor where the student fell and the surrounding rooms, and found nothing in it at all, so I thought that if I used the same method as her to search, then it should be

There will be nothing gained either.”

Since he felt that the bathroom was a target that needed to be investigated, he would naturally have been more careful and careful even if the vice-principal didn't find anything. Ms. Keller actually ran into the bathroom in a completely invisible way.

"The bathroom is the place where the incident occurred, and according to Muggles, the murderer will always return to the scene of the crime uncontrollably, secretly spying on the police's progress in handling the case, and taking the opportunity to check to see if there is anything else that he did not clean up at the time.

Clean clues remained at the scene, so I entered the bathroom in an invisible state. In fact, I mainly wanted to wait and see."

After the incident occurred, the corridor where the incident occurred and several surrounding rooms were temporarily blocked, and this blockade has actually lasted until this moment more than ten hours later.

"I didn't plan to stay in the women's bathroom for too long. After all, the law of criminals returning to the crime scene is not 100% accurate in the process of detecting Muggle criminal cases. So, I

Although I thought at the time that the person who had done this would probably go back to the bathroom, the main purpose was actually to go into that bathroom and explore it carefully.”

While waiting for the murderer who might not return to the scene, she started groping and searching in the bathroom. Ms. Keller actually found the magic surveillance method left by the murderer in the bathroom.

And this monitoring method is none other than what Violet and the others had guessed at the beginning, a convenient and easy-to-use double-sided mirror.

"It's actually a double-sided mirror that has been casted with transparency magic and sound-shielding magic!" At first, I speculated that this mirror might be hung on the wall directly opposite the faucet in question, but I never tried it.

As they started to search with their hands, Violet and the others knew very well that even if they were wearing an invisibility cloak to do this, if someone accidentally touched the mirror and caused the mirror to vibrate, then there might be a spy who was using the mirror at that time.

There is a possibility of being alerted.

Until now, they had never looked for the magic monitoring equipment in the women's bathroom, but the principal revealed this mystery. Violet and the others were quite happy. After all, this fully proved that their ideas were not correct.

wrong.

"So what? What did you do after you found the mirror?" Originally, they thought they would not get any reliable evidence or clues today, but at this moment they discovered that they could really find the spy who appeared tonight.

After being arrested and brought to justice, the Aurors headed by Charles were obviously very happy and excited.

"I did not remove the invisible magic of the mirror. After all, the wall where the double-sided mirror is hung is facing the faucet in question, and the special mirror in the bathroom is hung above the faucet. Therefore, once I choose to

Unlock the invisible magic of the double-sided mirror inside, and the mirror above the faucet will accurately display the scene on the wall."

"And if the person using the mirror happens to be looking at the mirror at that time, then as soon as he sees the mirror above the faucet and the double-sided mirror on the wall reflects its original shape, then he

He will definitely destroy the other mirror he is holding in his hand immediately, so as to prevent his situation from being exposed through the mirror to those who want to find him."

Because of basically similar considerations, the sound-blocking magic of this mirror was not released. Ms. Keller knew very well what would happen if she did this in a seemingly empty bathroom.

The sound emitted outside the mirror will obviously be transmitted to the other mirror again. Even though the sound emitted is not loud, it can be covered up because there are no other users talking in the bathroom.

Therefore, once the sound shielding magic of the mirror is lifted, the spy who hears the sound from his side through the mirror will definitely destroy the mirror directly, just like hearing an echo.

"I didn't know at the time that the entrance and exit of the secret room was in that bathroom. Of course, I didn't know that the monster in the secret room was actually a basilisk. Therefore, although I found the enchanted double-sided mirror in the bathroom,

But there is still no way to connect this mirror with the boys in the hospital and Winnie."

Even though he knew that they must be inextricably linked, there was just no way to use a set of reasonable logic to connect these different things together. In fact, Principal Keller was in Violet and the others.

After I spoke clearly, I finally figured out what was going on.

"After I found the mirror, I stayed in the bathroom for a while, and then a person who used magic to hide his figure actually came. Although I couldn't see directly who walked in with my naked eyes at that time,

However, when the mirror hanging on the wall was recycled, I was still sure that the person visiting the bathroom was our school doctor, Mr. Pompidou."

If the mirror is hung in a small cubicle separated by wooden boards, then Principal Keller, facing the male school nurse who comes to recycle the small mirror, will definitely immediately conclude that this is a person who likes to spy on female students going to the bathroom.

The pervert then fought with him on the spot and captured him.

However, the place where the small mirror was aimed was the inexplicable faucet. Therefore, Principal Keller, who did not know what was going on at the time, decided to dig out the truth of the matter.

Therefore, we chose to stand still for the time being, doing nothing and saying nothing.

"Now, combined with the words of Violet and you, I have completely figured out what is going on. And how does our Pompidou school doctor use the small mirror in his hand?

, I am equally clear about it now.”

Since he only needs to confirm whether Winnie has returned to the bathroom and opened the secret room, Pompidou does not need to care about what kind of conversation is going on in the bathroom. As long as he can see that person in the screen

It is enough to turn on the faucet and find out whether the entrance and exit of the secret room has been opened again.

Therefore, Pompidou actually also cast sound-blocking magic on the mirror he was holding.

"It's not just about blocking the sound. As a person who needs to take out a small mirror from time to time, our school nurse doesn't want to expose the fact that he is using a double-sided mirror to spy on the situation in the women's restroom. So naturally,

You need to ensure as much as possible that no one will notice you looking at the small mirror on a daily basis. So, how do you think he looks in the mirror on a daily basis?"

"This..." She didn't know Pompidou very well, and she didn't spend a long time with Vincent and Amir dealing with the school doctor. Violet was really confused for a moment.

I don’t know how Pompidou looked in the mirror.

He had his own independent office in the school hospital, and he didn't have to move around to teach students. Pompidou had plenty of time to stay in his office and look at the small mirror with confidence.

Someone in the school was injured or sick. There was no way to predict in advance and prepare according to the timetable. Therefore, Pompidou had no idea who would appear in the school hospital at what time.

There is no guarantee that when Winnie has time to look at the small mirror, Wei Ni will open the secret room, and there is no guarantee that when Winnie opens the secret room, he will just have the conditions to take out the small mirror and examine it.

How did Pompidou ensure that he could look in the mirror without arousing suspicion from others? No one could answer this question for a while.

"This morning's game, the school doctor went to the stadium with us to watch it! Moreover, according to the facts provided by Wei Ni, the time when he opened the secret room entrance and exit in the castle actually corresponded to our seats in the stands around the stadium.

During the whole game, Pompidou has been sitting next to me, and I never saw him take out any mirror from any part of his body, so he really looked in the mirror.

?"

Although it is impossible to pay attention to her colleagues all the time during the competition, it is not just during the competition. It can be said that Crova has never seen Pompidou use any self-prepared mirror. Therefore, at this moment, she cannot think

After understanding the problem before her, she became confused.

"Klova, don't limit your thinking!" Facing the vice-principal who had no idea where Pompidou had hidden the double-sided mirror he used, Principal Keller smiled slightly:

"In the final analysis, a mirror is just a piece of glass and a piece of coating. And hasn't our school nurse been carrying around two pieces of uncoated glass very openly?"

"Ah, I know, it's glasses!" Because of the hint given by the principal, they suddenly realized that when the vice-principal said this, Violet and Vincent also guessed the answer.

"As long as you use magic to process the mirror and remove the reflective coating on the back of the mirror, you can then transform the piece of glass into your own spectacle lenses. Pompidou only needs to use a little more magic to make the double-sided mirror appear

It is enough that the image cannot be seen by the person on the other side of the spectacle lens."

On weekdays, when you face the school doctor who wears a pair of glasses and looks gentle, even if you look at him carefully, you will only notice that the reflection on the glasses reflects the current situation of the school doctor's environment.

No one who is looking at the school nurse would know that there is actually a completely different picture on the other side of the spectacle lens.

"Because the coating on the back of the mirror was removed and the glass piece was placed directly on the bridge of the nose, it was impossible for Pompidou to see clearly anything so close to his pupils. When he looked around through the lenses of his glasses,

In the environment, the visual effects received will not be interfered by the real-time scene in the bathroom. When Pompidou wants to see the situation inside the bathroom, he only needs to take off his glasses, which is enough.

"

"Yes, that's what you guessed." Facing the few people who guessed the answers, Keller smiled and nodded, and continued: "In fact, before today, I noticed that our

The school nurse often takes off the glasses to clean them, or complains that the bridge of his nose is sore from being pressed by the glasses, so he takes them off as a matter of course."

"No matter which one of the above banners is used, if you take off your glasses, you only need to use the glasses handkerchief you carry with you as a reflective coating on the glass to ensure that the glasses become completely colorless and transparent, and restore one side of the glasses.

The mirror should have the function, so in this way, the school nurse can naturally peek into the situation in the women's restroom anytime, anywhere without being noticed by others. "

"He's quite smart!" Because of the explanation given by the principal, she immediately recalled the scene she saw this morning. Krova clearly remembered when Winnie opened the secret room entrance and exit in the bathroom this morning.

, Pompidou, who was already seated in the stands, took off his glasses and wiped them very naturally.

"..." She, Vincent, and Amir were all not close to Pompidou. Therefore, Violet had not actually noticed that Pompidou liked to take off his glasses to clean them.

, or occasionally pinch the bridge of my nose, which is said to be sore from being pressed by the glasses frame.

In the past days of direct dealings with Pompidou, either Winnie acted with them, or it was obvious that it was impossible for Winnie to run to open the secret room. It was precisely because of this that Violet

, that’s why he didn’t notice Pompidou’s move.

After all, in these two situations, it makes no sense to take off your glasses to monitor the situation inside the women's restroom.

"Didn't I repair the telescope while processing documents in my office this morning? Since it has been repaired, it must be taken out for actual use and minor adjustments made. The reason why I am now proposing Peng

Pompidou's idea of ​​transforming his double-sided mirror into lenses was actually due to the fact that during this morning's competition, I accidentally observed with a telescope that Pompidou took off or wiped his glasses several times.

Or he raised his hand and pinched the bridge of his nose."

The players on the court fly so fast and make sharp turns. Faced with this kind of game where if you are not careful, you will miss many wonderful shots. The school doctor with poor eyesight frequently takes off his glasses.

The way it is done really makes people think and feel something is wrong.

And if Pompidou doesn't care about the situation on the court at all, but just needs to take off his glasses and pinch the bridge of his nose to peek at the situation in the bathroom every ten minutes, then what he did will be understood.

A completely reasonable explanation.
