My avatar is the heroine

Kuroko leaned back, feigning composure, but what troubled her was that her main quest completion rate was not at its highest.

Currently, it seems that only about 50% has been completed.

"As expected, simply stopping the plan and ensuring the safety of the surviving sister is not enough to completely complete the mission. It seems that X's re-emergence mission is quite difficult."

However, bringing back the sisters who died long ago seems to be no easy task.

Based on the information provided by the system beforehand, it was simply impossible.

Black Eyes frowned, wondering what the problem was.

She tried opening the system panel and started looking at each item one by one.

Within minutes, she noticed a piece of information.

[Due to increased participation in major events, access privileges have been upgraded.]

[Currently, it is permissible to rewind to a time before the time travel, bringing the surviving sisters back to the present.]

[Note: History cannot be changed.]

This is Python again:

Then, the moon fell.

Chapter 257 Preparing to Save Ten Thousand Times

"Bring the sisters back without altering history?"

Emmm...

Black Eyes fell into deep thought.

Well, how should I put it? If we take the sisters away, it's impossible for history not to change, right?

After all, so many people were watching. Accelerator killed the sisters one by one, and the deaths of nearly 10,000 Misaka sisters were almost inevitable. Accelerator himself had to conduct experiments several times a day.

Although I don't know why this guy has such patience, I couldn't stand doing this kind of thing every day, it would never end.

"If we don't want to change history, it seems we can think of two methods for now."

The first method would be for her to use a clone to impersonate her sister and be killed in place of the original. However, she doesn't have a Misaka clone, and even if she did, being killed over ten thousand times in various ways would be too cruel. After all, she's not Yukino.

The second method is to have Rikka use illusion magic to simulate Misaka Sisters.

However, the biggest problem with ability simulation is how to ensure that it can deceive everyone at the same time. Moreover, when Su Lin arrived at the corresponding time, he was also seen by the Sky Retrace, which is equivalent to changing history.

A change in history is equivalent to a change in the timeline, and also to a change in the future.

The most direct result was that the development of events in the time Su Lin traveled to was highly uncertain, which in turn led to changes in her own future.

This could very well lead to completely unpredictable paradoxes in this spacetime, and what will happen then will be entirely beyond our control.

"Speaking of which, I'm a little curious. If I went there and changed the timeline before I got involved, wouldn't that change things after I arrived? And what impact would that altered version of me have on the present me?"

It's important to understand that the A Certain Scientific Railgun universe isn't the kind of extended world where making a choice creates a parallel universe. The answer is like the question of whether you can exist if you travel back in time and kill your grandmother. You'll never know unless you actually try.

In Su Lin's original world, time progresses linearly, and no physical theory can find the possibility of time reversal. In other words, spacetime itself does not allow for contradictions.

The fact that one can only move towards the future and not return to the past means that there is a fundamental difference between one's past physical world and the present world where magic and science coexist.

Misaka Mikoto didn't realize at the moment that Kurohime's attention had shifted elsewhere.

The two of them chatted idly, and before they knew it, the water had gone cold.

"So we've been chatting for so long? After talking to you for so long, I really can't tell you're a guy. Your personality is very similar to a girl's, and we get along very well."

"Ha...really? Hahaha."

I gave an awkward laugh. It's not like I can control my clones properly all the time, but it's really easy for problems to arise over time.

"Big sister, waaaaah, please don't say things that hurt me like that." Kuroko's sobs came from the other side of the wall.

She was leaning against the wall when she heard Misaka say that they got along well, and she immediately collapsed to the ground in despair.

"Heizi seems to be dying. Go and keep her company."

Kurohime couldn't help but laugh, and then got up from the bathtub.

The wet liquid dripped down her body. She turned her head and glanced at the mirror next to her. The cute girl in the mirror had short, wet hair and a slightly wicked smile on her face. She looked like a minor, but she was always very alluring.

"Well, I'll be going now. Speaking of which, you're really beautiful, with such fair skin. As a girl myself, I'm a little envious."

Misaka was smiling and about to continue speaking when Kuroko suddenly appeared and dragged her away from where she was.

A loud thud came from next door immediately afterward.

"Kuroko, what are you doing? Why did you suddenly teleport me here? I'm not even dressed yet!"

"It's the same whether you wear it in your room, Onee-sama." Kuroko's voice was serious, but after a few seconds of pause, her tone suddenly changed, becoming full of wickedness. "So Onee-sama is naked, huh? In that case, let Kuroko give your perfect skin a good scrub, hehehe..."

Crackling sound~~

A sudden electric shock was followed by a scream, and then the next room fell silent.

Why do I have this ominous feeling?

Black Eyes shook his head and stepped out of the bathtub.

Looking at her wet feet and the slightly bulging part of her chest, she suddenly couldn't help but swallow hard.

To be honest, Misaka Mikoto's body isn't usually the type to easily arouse male desire, but this time, seeing herself like this, she suddenly felt a strange urge.

"Thinking about it carefully, wouldn't it be great to use a clone to do something whenever I have an idea?"

Although it might inexplicably become yuri (lesbian) in some way, it seems that due to my mindset, using a woman's body would be more stimulating.

After drying herself with a bath towel, she looked at her body, which didn't look like that of an adult at all, and reached out to rub...her chest.

"Hiss, I'm getting into it. It seems that even assassins are no different from normal people in terms of their senses."

So even if Kurome didn't die in Kill la Kill, she would eventually have romantic feelings like any other girl, right?

Will Akame remain single forever?

Many thoughts flashed through her mind, and she shook her head violently again.

I feel like some kind of hybrid mind monster. Although they are all interconnected, the personalities brought by different bodies affect each controlling part. This feeling is very strange. It is a single brain, but it selectively adopts different methods when dealing with different events, and I can clearly feel the differences.

"So the saying that personality determines destiny is really true. When Kurohime is dealing with things, she can't help but want to kill."

……

In the time that followed, Su Lin began to consider returning to the past to completely save the Misaka Sisters.

For safety, he would first collect all the records from each previous experiment, then have Rikka return to the past while in a genjutsu state, using genjutsu to simulate the murdered Misaka Sisters, while simultaneously rescuing the real one.

If nothing unexpected had happened by then, Toshinobu Fubuki should have already implanted the emotional program into the Misakas, and this program had been intercepted by Last Order... that cute little loli Misaka.

As an important terminal, if she develops complex emotions, then the other Misakas are really no different.

"At that time, we just need to get the rescued Misaka Sisters connected to the current network. However, we can't hide it now, and this matter will probably raise the danger level."

I wonder what Aleister will think this time; he might just do something he can't help but do.

Chapter 258 Rescue

[This 125-cubic-meter space has been isolated from that worldview; please prepare for time travel.]

Standing before a device similar to the time machine in Steins;Gate, Kurome and Rikka took a deep breath and stepped inside.

The journey begins.

The location has been determined.

The first test of the Absolute Ability Evolution Project took place in a huge indoor testing ground.

With a burst of powerful energy, the barrier of time was shattered, the laws of time were completely reshaped, and the clone in front of the main body, along with the huge external equipment, also disappeared.

"It's a wonderful feeling that even though my body is in different times, we can still connect in sync."

When traveling through time, looking out through the transparent glass of the instrument reveals bizarre and fantastical scenes, with images flashing by occasionally, representing events that occurred at different times.

After waiting on the main body for about ten minutes...

[You have reached your destination. When you step out of the time machine, you will return to this world.]

The system will disguise you accordingly.

With this prompt, Kurohime and Rikka took a deep breath and stepped forward.

Indoors, at night.

In the hall, Accelerator had just entered the door when he saw Misaka Mikoto holding a gun.

"Oh, so you're the experimental opponent, aren't you?"

He casually asked a question, but his attention was not drawn to Kurohime and Rikka, who were standing a few meters away from Misaka Mikoto.

"Although having the system shouldn't be a big problem, my own illusion magic should also be useful."

Taking advantage of this moment, with a thought, the illusion changed, and the position where Misaka Sisters were standing was replaced by a virtual entity.

Of course, neither Accelerator nor the staff present were aware of any of this.

"Excuse me... what's going on?"

Misaka suddenly looked over in a daze, but Rikka's fantasy did not interfere with her.

"I'll take you to a place, and once we get there, you'll understand everything."

He stepped forward and took the other person's hand, but she pulled away.

“I need to conduct relevant experiments,” Misaka said in a serious tone.

Her expression was extremely serious as she raised her weapon, looking as if she was about to give it her all.

"Someone will take your place in the experiments. Come with me."

Before she could even resist, Kuro-tomi scooped her up and ran back into the time machine.

As planned, Rikka was allowed to maintain her illusion, and was tragically killed by Accelerator.

Clearly, the old man was very disappointed with this first experiment.

He had hoped for a fair and exciting duel with LV5, but his opponent turned out to be a weakling who relied solely on guns.

……

After returning to reality via the time machine.

"OK, how does it feel?"

Clearly, when Kurohime asked that question, Misaka Sisters were completely stunned.

She connected to the current Misaka Network and witnessed the deaths of herself and over nine thousand others, as well as the various events that followed.

Although I was the first test subject, the feeling after receiving so much information all at once was...

“I’ve taken you to the future. Also, given the inherent dangers of Academy City, you must not tell anyone about this normally.”

It's likely that Aleister already knows, because the danger level in front of Kurohime suddenly soared to five percent. This exaggerated increase is probably because the other party saw some possibility in him that even he hadn't considered.

Indeed, the arbitrary control over the rules of time is completely contrary to the laws of the technological side; this is probably something only the magical side can achieve.

However, now, this monster has actually appeared among the ability users.

“I need to hurry, Aleister is probably still observing.”

With this thought flashing through her mind, Kurohime began to get busy.

Over nine thousand times, that's probably how boring Accelerator gets.

Although Kurome saved many people at once, the total time Accelerator spent killing them is still incredibly astonishing.

Even if each Misaka Sister dies every 10 minutes on average, it would still take close to 10 minutes.

Fortunately, most of the Misaka Sisters were defeated in one or two moves. Including the dialogue and chase during the process, each experiment lasted about 4 minutes on average.

That is to say, the total duration is approximately 666 hours.

"I'm afraid this is going to drive me insane."

The thought of having to simulate being killed for 600 hours straight, witnessing firsthand how Uncle One killed Misaka Mikoto in various ways, made Su Lin rub his eyes helplessly.
