The girl with white hair and red eyes is serious about revenge

"Could those two seats be the key?"

"It's possible. You can go and have a look."

Carly said, and walked with Perlis to the two tables in the second to last row by the window. They first looked in the drawer and found a piece of paper in it as well.

They took out the paper, and this time it was a children's painting of three stick figures holding hands in the sun. On the left side of the painting was a very tall strange building, and on the right side was a distorted drawing of a school.

There were dots of black ink on the screen, leaving two tear marks on the face of the taller stick figure in the middle, making her look like she was crying.

The three people in the painting all have long hair expressed by messy lines, which means they are all women. The crying one in the middle is the mother, and the ones on both sides are her two daughters.

Perlis felt a chill in her heart when she saw it. She turned the painting over and found a line of words written in black ink on the back:

“I want to go back to yesterday.”

What does this mean? Who wrote it? Who were the previous owners of these two seats?

According to Perlis's speculation, the two shorter stick figures in the painting should represent the former owners of the two seats.

Who left the words on the back? Judging from the crying people in the painting, was it their mother?

What happened in this school back then?

This painting is obviously normal matter. When Perlis opens the factor vision, it has factor entanglement, which is different from any other matter in the [Netherworld].

It should be able to be lit up... just like I lit up Miss Ayane's little note at Umigiri Island...

But how to do it?

Just when Perlis was at a loss, Carly had already come to a conclusion:

"I really want to go back to yesterday. Does it mean restoring a certain state in the past?"

"what do you mean?"

"If we sit in their seats, will we see their mother?"

As soon as Carly said this, Perlis looked at the painting again. The smiling stickman with black tears seemed to be staring at her.

"If I can help it, I don't want to see..."

"But this might be a way to break the impasse," Carly pinched Perlis, "Be obedient, let's give it a try."

"Um..."

Pearlis sat in the window seat, and Carly sat next to her, and the two of them filled the seats for the students whose names had been crossed out.

When they were seated, something strange happened -

"Zizzizi..."

The surrounding space was suddenly infected by electromagnetic interference, broken snowflakes emerged, making the scene somewhat distorted.

The interference became stronger and stronger, and finally penetrated into Perlis's brain like some kind of pheromone. Black figures gradually appeared in her vision.

Those figures filled all the empty seats in the classroom, and they all looked at the blackboard like a flock of sheep crying for food.

A tall figure appeared in front of the blackboard and behind the podium. Perlis couldn't see her face clearly, but she could tell from her hairstyle that she was the mother in the painting:

"...read with me, Twinkle, Twinkle Little Star, the sky is full of little stars..."

"Twinkle, twinkle, little star..."

"The sky is full of little stars..."

As the ethereal nursery rhymes were recited, the teacher's face at the podium became clearer and clearer - she was a woman, a beautiful and kind female teacher.

While reciting, she looked gently at the positions of Pearlis and Carly and nodded encouragingly.

Perlis was a little flustered by her gaze, but the next second, everything around her suddenly returned to normal.

The teacher disappeared, and the noise like electromagnetic interference in the surrounding space disappeared, and it became frighteningly quiet.

However, those students did not disappear.

They all turned their heads and stared at Pearlis and Carly with no expression on their faces.

They just stared, and stared.

......

7) Paradise Lost (Part 4)

When those eyes were focused on her face, Perlis felt her heart tremble slightly, and the sense of foreboding continued to deepen.

She reacted as quickly as possible - wrapping the paper around her butterfly knife and then setting it on fire with her factor energy.

"call--"

The flames started burning, and the distorted light suddenly illuminated the entire classroom, and all the students stood still.

"Huh? What's going on?" Carly was a little surprised to see how skilled Perlis was.

"Candlelight can anchor shadows. It seems that the situation here is the same as in Ankamouth."

Perlis once again recalled the note that would never burn in the small room on Sea Mist Island. It was obvious that the matter from the upper world would remain in a superposition state in the lower world and would not be destroyed.

This also means that the marks of these students before him will remain in the underworld.

So, the two students who were crossed out on the list...the teacher's two children, were not left here?

"What should I do next..." Perlis began to think.

"Why not try looking out the window?" Carly suggested.

So Perlis did as she was told. She held the candle close to the dark window, but saw nothing.

"Nothing," Perlis muttered, "If there was a note in the desk drawer, then there should be other information here."

"Look at other drawers?" Carly glanced at the motionless students and gave up the idea. "If I didn't say anything, they probably wouldn't be happy."

"The carrier of information..." Perlis frowned, "Let me think..."

While thinking, Perlis raised her head and saw the blackboard behind the podium. Her eyes lit up:

"Blackboard!" "It's a blackboard!"

The two kids said this in unison, and then smiled at each other. They seemed very happy that they thought of going to the same place at the same time.

So, in this terrifying and gloomy classroom filled with faceless men, the two of them carefully crossed the aisle and came to the blackboard.

Perlis shone the candlelight on the blackboard, and sure enough, lines of handwritten words soon appeared on the dark board:

"...I have been teaching here for eight years. My children and I have been through five hard years together, but my research has been difficult to progress... There will probably be no progress..."

"...Will that voice be lying to me? Will the students forgive me? Will He forgive me?..."

"■■■, ■■■, you have to escape. Mom has done something wrong. It's too late now..."

"...I'm sorry, Principal, I didn't listen to your advice..."

"A flash, a glitter, a sparkle..."

The handwriting on the blackboard changed from neat to hideous, which obviously meant some kind of transformation process.

When she saw the last poem, Carly trembled noticeably.

"Just like my mother's last words..."

"What did she see?" Perlis's voice was very low. "No, the question should be, what did she do?"

Pearlis and Carly turned around at the same time, and suddenly, they found a photo frame on the podium.

The photo frame obviously appeared only after being illuminated by candlelight, projecting a moment in the past.

"what is this?"

Pearlis carefully picked up the photo frame, placed it in front of her, and looked at it with Carly.

There was an office on display there. The space was neither too big nor too small, very tidy, and surrounded by bookshelves.

“Was this there just now?”

"Probably not," Perlis felt her eyes blurry, "Strange..."

In Perlis's vision, the image in the photo frame became increasingly blurred, and a strange radiation that did not resemble light emanated from it and hit her retina.

When Pearlis came to her senses, she found herself standing in the office.

"Huh?" Carly was beside Perlis, also very surprised, "Why..."

“It seems that the spaces of this school are connected in this way.”

Pearlis looked at the table in the middle of the office. On the table was a photo frame, which showed the classroom in it.

This obviously cannot be the mechanism of the [Netherworld] itself, it must have been done deliberately by someone.

The "people" here can only be the [Black Tide Cult].

But how could those cultists have the power to control the [Netherworld]? They were just a bunch of lunatics, at most lunatics with a strange fetish for the Black Tide.

unless...

"【Black Emblem】."

As Perlis said this, she looked at Carly, who nodded.

"Yes, you said before that they used that thing to control the Kraken in the Pure Water Lake," Carly agreed. "In that case, it seems that we are on the right track. They are somewhere under this school."

"Ah."

Perlis nodded, then walked to the bookshelf in the room and turned on her factor vision.

She soon discovered the only book with factor entanglement - like the painting, it was a source of information from the upper world.

Perlis pulled out the book and read the title:

"...Records of textual research from the previous era...written by Sakura Sugimori..."

Wait... Shansen? That can't be a coincidence, right?

Both Perlis and Carly thought of a pair of sisters named Shansen - Lian and Aoi.

This book...is related to those two sisters?

If this book was written by that teacher, does that mean...the two empty seats in the class are...

Perlis looked at Carly, who shook her head and said:

"I don't know Aoi and Rei's backgrounds. In fact, it seems that even they themselves don't know."

"Didn't you try asking?"

"I asked this question at a party before, but when I asked it, they all seemed to be in a trance and couldn't speak..."

Carly said, frowning slightly:

"I thought it was because they had some past that they didn't want to talk about, so they quickly apologized... Aoi said at the time, 'No, no, I was just distracted', and I thought she was just trying to smooth things over..."

Carly's voice became quieter and quieter, her eyes widening slightly as if she remembered something.

"Carly?"

"I should have thought of it earlier..." Carly murmured, "When she was on the 'Blue Reef'..."

At that time, Aoi and Carly were chatting, and when they talked about Lian, Aoi said something relaxed and comfortable:

"It's okay, it's okay. When we were kids, she was angry because I forgot to bring food when I went out to play. I remember that we lived in... Strange, where did we live?"

I should have thought of this a long time ago... Aoi obviously doesn't remember her childhood experiences. Who can't even remember where they lived when they were a child?

At that time, the "Blue Reef" was about to sink into the netherworld rift and was about to dock at Black Island, so Carly did not ask any further questions and forgot about it afterwards.

Judging from the current situation, Aoi and Lian were most likely deprived of their memories before a certain stage, which is why they lost their memories of the past.

"The state of their dull thinking... It's almost like..."

"【Deep Diving Cradle】." Perlis murmured.

The two looked at each other, and at the same time, they both thought of Laplace's face.

"If Sakura Shanmori is the mother of the two sisters, perhaps this operation can also uncover the mystery of their past."

Perlis whispered as she walked over to the desk and placed the book on the table, lighting it with candlelight.

Then, two shadowy figures appeared on either side of the desk and began a conversation.
