Following behind his senior sister, Mitsuki Umihara and her came to a large apartment building deep in the 19th school district.

The reason why it is said to be a large apartment is because in a sense, it was once a landmark building of the 19th school district.

It was a 45-story building that was once planned to be the largest number of residents in the 19th School District. For a while, it did serve a similar purpose. But with the rezoning of the 19th School District, the iconic condominium has completed its historic mission and will be abandoned from next month.

It was thought that the building should be uninhabited anymore, but now it seems that there are still people who have not moved - although there is only one.

"Was it a surprise?"

Yan Bi placed the teacup in front of Haiyuan.

In a room on the 41st floor, Mitsuki Umihara sits at a tea table in the middle of the living room. There is actually no furniture in the room anymore, and it seems that the owner of the room has largely finished moving, but he has not left for the time being.

However, Kaihara never thought that he would one day be invited by his senior sister to his residence, although it was a residence that was about to move out.

"Some, indeed. Generally speaking, it is normal for students from outside to live in the Seventh School District. ”

"Yes, but I'm not too fond of places that are too modern, at least they still have an old-fashioned feel. But that's the end of it......"

"yes."

Mitsuki Haihara also didn't know what to say. Could it be that the senior sister is a little unrelieved because she has to move? If that's the case, it seems that there is nothing more to do than listen to her.

"It's the same everywhere else. Because of the relocation, this small residential area is actually uninhabited anymore, and as far as I know, I am the last person left here. ”

"Oops, oops, ......"

Unexpectedly, although I have always felt that this senior sister is a very nostalgic person, and even likes to use old-fashioned mobile phones, but she is really nostalgic to such an extent......

"No, it's not." Ji Yanbi said in a light tone, "I don't deny that I am very nostalgic. But I value the memories that stay in the memories more than the things themselves. Because memory is part of the personality, and perhaps even the personality itself is shaped by memory. So the reason why I value memories is probably because I value my own personality. After all, perhaps 'one's own consciousness' plays a decisive role in this. ”

Actually, it's not a pessimistic thing. I just want to pay more attention to these memories that are about to become a thing of the past, and to experience myself more realistically. That's pretty much it.

Umihara generally understood her words. As a superpowered, since it is based on the "reality of the self", it is natural that there will always be some people who will cherish their own part extraordinarily. Whether it's a memory, a personality, anything.

Maybe the senior sister who is the "original stone" of self-awakening personal reality.,I think it's more concerned about this.。

In my own impression, the senior sister seems to be confused about what is a personal reality. Although, according to Eugene Wigner (note: Nobel laureate, one of the founders of quantum field theory, and the proposer of the paradox of "Schrödinger's cat", Wigner's friend), the reaction of consciousness to reality should be taken for granted. But even in the school city,It's hard for his point of view to be fully accepted.。

And I'm afraid the result of being entangled in this will not be too pretty. Otherwise, Stephen Hawking would not have shouted angrily, "I'll get a gun and kill that damn cat!" In fact, even today, when it is possible to keep a large number of particles in the state of "Schrödinger's cat", Schrödinger's poor cat is still unknown.

It is natural for a "rough stone" like a senior sister to be puzzled by it.

However, Yan Bi smiled. As if she had heard something helpless, she denied Haiyuan's speculation.

"I'm not thinking about it that deeply. Just ......"

She picked up the teacup that Haihara had drunk and stood up, turning to the living room window. On a small table there was an electric kettle, which seemed to have been used during the transition period of the move. She walked to the window as if she was about to refill the cup for Haiyuan, and put her hand on the electric kettle, but there was no next move for the time being.

"It would be nice if time and self could always stay in the past......"

Haiyuan heard her say this.

"That's impossible. The second law of thermodynamics is irreversible, and time cannot be stopped. No matter how much we change, we can't go back to the previous moment. There is no way to keep the ego the same, so our position is constantly changing. Even if you don't want to touch the future, the future will come unstoppably. Shut yourself up in memories and think it's stupid to change yourself. Therefore, if you want to become your true self, it is necessary to keep moving forward. Memories are for mourning, not for indulgence. Even if one day we all grow old, at least when we look back on the past, we will smile at what we have done, and that will be enough. ”

These words were said by Umihara's father to his siblings on the day Dome officially became his family. It is also what Mitsuki Kaihara always remembers in his philosophy of life.

"That's a good point...... Light. As if he was a little hesitant, he turned his back to Haiyuan and said softly.

But with her words, Mitsuki Haihara actually felt an inexplicable sense of tension in his heart.

"Time is irreversible, so even if you dwell on the past, what happens will not change. Right or wrong, good or evil. And also...... Whether it's a crime or a punishment......"

In a soft and listless voice like a murmur, Yanbi slowly turned her head.

Although she wore a seemingly gentle smile as always, her appearance really startled Kaihara.

Because, those red and swollen eyes are clearly like they have cried bitterly. Even though she was smiling gently, it was clear that she was crying. Having said that, however, not a single tear could be shed.

It wasn't as simple as wanting to cry but not being able to cry, but it was like blood and tears had been drained.

It wasn't like this at all, how could it suddenly become like this?

"Sister Bi ......"

Looking at her appearance, Haiyuan couldn't say anything for a while. He couldn't understand it at all, obviously just a moment ago, the senior sister was still the same as before.

He didn't have time to think about it, and an almost instinctive warning made him reflexively jump backwards.

In the next moment, he saw countless black "threads" sticking out from the place where he had been sitting.

As he landed, Haihara heard a click, and the chair he was sitting on was split into countless small pieces.

In fact, the chair had been completely shredded at the same time as the black thread stretched out. It's just that in the absence of external forces, a certain unstable equilibrium is still maintained. Until his feet hit the ground and this equilibrium is broken.

What is this?

Before he had time to think about it, Kaihara temporarily handed over the dominance of his body to instinct. He relied on the reflexes he had developed in martial arts training to quickly take another sideways leap. Sure enough, the black thread stretched out frantically from where he was again.

Taking advantage of this interlude, he looked up at the only suspect who had caused all this, his former senior sister. He didn't understand what the hell was going on, he couldn't figure it out anyway.

With her arms folded, she gently sucked her right index finger in such a lazy posture, looking like a girl in love who was pretending not to care and listening to her boyfriend's soft words and secretly rejoicing in her heart. However, she still had a distressing smile as if she was crying. She just looked at Haiyuan and didn't say anything.

There was no choice but to subdue her first and then try to figure out what was going on.

Confirming this, Kaihara didn't want to jump forward with his fighting footwork, and this time the black line that covered the sky and the sun stretched out directly from the direction facing him at high speed, covering almost the entire field of vision like a waterfall. Haiyuan changed his steps slightly, and suddenly reached out and grabbed the black threads and ripped them to the other side. The threads were enough to cut through furniture, but they didn't hurt him in the slightest under the curing effect he had prepared to do with the telekinesis of LV.4. He quickly followed the momentum and threw a left high kick towards where Yanbi was.

The kick flew five meters away, and it didn't stop until it hit the wall.

But, no, not at all.

The kick just now, the feeling that came back was not a kick to the human body at all, but like a kick to a piece of hard metal.

Glancing down at the black threads still in his hand, they ...... Is it hair?

That's right, it's hair. It's the beautiful long hair of the salt bi.

"Hehe, scared, right? Light ......"

It sounded like a laugh, but it sounded like it was about to cry.

The cry that was completely distorted by the smile was spreading along with the long hair of the Yan Bi.

That's what Mitsuki Umihara saw. It's like lying on the ground, lazily leaning against the wall, and ......

The one that spread out in a radial shape, deep into the walls, floors, and ceilings, tens of thousands, hundreds of thousands, hundreds of thousands of black and translucent strands.

Pulled by these hairs, Ji Yanbi's body was gradually pulled up. It was as if he was lying in a huge hammock, hanging in the room, like a giant spider lying in the middle of a spider's web.

"Look, I look like this...... Weird, right? ”

I didn't really want to understand her words, but this scene, along with the touch he felt when he kicked her before, made Haiyuan think of a possibility.

"Sister Bi...... Are you a physical enhancer? ”

She has never revealed her abilities to anyone, even Haehara is completely unaware of it. But a series of phenomena just now made Haiyuan think of this possibility.

But Yan Bi shook her head.

"This is just the beginning......"

Although the meaning is unknown, it is so declared.

Strong as fiberglass, sharp as a metal wire saw, the black hair pierced from top to bottom, left and right, as if it wanted to spread all over the room.

"I don't understand...... Senpai. ”

Haiyuan, who lowered his head, asked so softly. Since there were only two people, Ji Yanbi could hear very clearly.

He swept his arm back, and all the black filaments seemed to be trapped in a strong adhesive, and began to move slowly until they stopped completely. The most incredible thing is that this phenomenon is actually covered by himself.

It is the use of the ability to release the kinetic energy layer by layer, and reduce the kinetic energy of the object layer by layer. Since telekinesis is the ability to move objects over long distances, it is natural that this application is not necessarily so wonderful in principle. But that being said, it's not easy to do.

"Senior sister, what exactly did you encounter?"

He didn't ask what was wrong, but what had happened. The subtle difference between the two comes from what he perceives and what he trusts.

"Like you said, time cannot stand, and what has already happened cannot be changed......"

Repeating Umihara's words mechanically, Shiobi had completely, completely, and inextricably fallen into an extremely distorted self-loathing.

Cha!

A strand of black hair was straightened vertically in front of her.

No, that's definitely not a physical enhancement ability!

Mitsuki Umihara suddenly realized an important problem.

The ability to strengthen the flesh can indeed strengthen the hair and body, but it cannot change the "total amount" of the body. But just now, Yan Yanbi's hair has definitely increased! That's something that only those who have the ability to regenerate the flesh can do.

Is there a person who has the ability to strengthen and regenerate the flesh at the same time?

Yes!

Although extremely rare, isn't there another one?

Just like in addition to the spiritual abilities such as mental induction, mind reading, consciousness amplification, and emotional transplantation, there is also the peak of the spiritual ability that can do these single-handedly, and is called the queen of Tokiwadai who is called the psychological mastery. Exploring along the ability of the meat system, it is natural to find that it is at the apex of the ability of the meat system, that kind of ability.

Even in the world, there are only three instances of extremely rare abilities.

Yan Bi stretched out her white wrist and pulled it on her jet-black hair. The scattered blood foam immediately evaporated into the air like dry ice at room temperature.

That ability can not only strengthen the body, but also include the regeneration of the body, and even change the appearance of the body.

Even...... Theoretically, it is even theoretically possible to completely change the substance that belongs to the physical body into something else!

On the ceiling, inexplicably flames ignited in an instant. It's like a dance, twisting the flames of shape.

That ability is called "physical change." The ultimate meat system ability that reigns on top of all meat system abilities.

Mitsuki Kaihara quickly slammed open the door, he was fully aware of what was going to happen next. Haiyuan, who is very good at physics, naturally knows that the dancing flame is a sign before the flash starts, a precursor to the explosion.

As he ran out of the room, a deafening roar rang out behind him.
