Star Rail, I, a Researcher, Joined the Chat Group

Hoshino Ai: "Eh, eh, eh? Going to Lord Chen Mu's world? I'm so jealous. I'm really curious about Lord Chen Mu's world too, but unfortunately, I don't have any Points."

Gotoh Hitori: "Me too, me too. I really want to see the starry sky in Mr. Chen Mu's world, see the universe, see the Star Destroyers, see the Space Station... Unfortunately, I don't have any Points either."

Kochou Kanae: "..."

Demon Slayer World.

Kochou Kanae blinked.

Seeing this, her heart stirred as well.

Hoshino Ai and Gotoh Hitori did not have any Points.

But because of Chen Mu, she had received an unexpected windfall.

She had them.

Chen Mu's world...?

How could Kochou Kanae not be curious about it?

It was only a thousand Points... It should be fine to visit Chen Mu's world, right?

Kochou Kanae hesitated.

After thinking it over, she decided to see how things went first.

Tokisaki Kurumi: "@Chen Mu, I wonder if that would be alright, Mr. Chen Mu?"

When Tokisaki Kurumi asked this, she was actually somewhat nervous inside.

Because, by a certain definition, Chen Mu understood her.

She did not know.

What kind of opinion Chen Mu had of her actions.

Chen Mu: "...I don't have any objections. If you want to come, you're welcome anytime."

Chen Mu: "But honestly, Miss Tokisaki..."

Tokisaki Kurumi: "Just call me Kurumi."

Tokisaki Kurumi relaxed inside, and a smile appeared on her face.

Though she did not know what Chen Mu wanted to say.

He had not refused her.

Tokisaki Kurumi then understood what Chen Mu thought of her.

Chen Mu: "Alright, Kurumi. To be honest, if you come to my world, aside from broadening your horizons and taking a look around, it might not serve much of a purpose."

Chen Mu: "Time, by a certain definition, is more taboo than space—especially when you want to change the past and alter the future."

Gotoh Hitori: "Eh? Isn't traveling between worlds just about broadening your horizons and sightseeing? Isn't Miss Kurumi an ordinary person? Why are we suddenly talking about something as lofty as time...?"

Gotoh Hitori was immediately rather confused.

Chen Mu was taken aback again upon hearing that.

Tokisaki Kurumi had not revealed her identity as a Spirit yet and was still pretending to be an ordinary person?

However, just as he was thinking that.

Hoshino Ai and Kochou Kanae spoke up.

Hoshino Ai: "No, no, no, Ichiri. No matter how you look at it, Kurumi isn't an ordinary person, right? Hasn't she exposed herself plenty of times in the group already?"

Kochou Kanae: "That's right. But rather than calling it exposure, it would be more accurate to say that she never deliberately hid it in the first place."

Gotoh Hitori: "Eh, eh, eh! Is that so?!"

Gotoh Hitori was stunned.

She had no idea. Could it be that she was the only one who had failed to notice?

Tokisaki Kurumi: "Ara~ Ichiri really is adorable."

Tokisaki Kurumi chuckled softly and could not help speaking up.

Ever since learning that Chen Mu knew everything about them, Tokisaki Kurumi had not intended to hide her identity any longer.

She had not concealed anything at all while chatting with everyone.

Hoshino Ai and Kochou Kanae had clearly noticed that Tokisaki Kurumi was no ordinary person.

They had not expected someone to remain completely unaware.

Gotoh Hitori: "Ugh..."

Once Gotoh Hitori realized this, her face flushed with embarrassment.

She now understood just how huge a blunder she had made.

Hoshino Ai: "But although I guessed long ago that you were extraordinary, Kurumi, I never expected Lord Chen Mu to start talking about time, changing the past, and changing the future right away. Holy crap, Kurumi, aren't you secretly some big shot too?"

Tokisaki Kurumi: "Not at all. Compared to Mr. Chen Mu, I'm far inferior."

Tokisaki Kurumi: "@Chen Mu, Mr. Chen Mu, since you know about me, may I ask you to help me? I'll definitely repay you. I'll agree to any condition, no matter what it is. Pitiful and adorable.jpg."

Chen Mu: "...How do you want me to help?"

Tokisaki Kurumi: "For example, creating a Time Machine or something..."

Chen Mu coughed violently. "Cough, cough, cough. You really think highly of me. But if I study it, it's not entirely impossible."

What?!!

Date A Live World.

Tokisaki Kurumi froze, then her eyes immediately lit up.

He could actually do it?

Though she had thought from the very beginning that Chen Mu could probably do it.

Still.

Receiving confirmation for real filled her with surprise.

As for the others in the Chat Group, hearing their conversation left them clicking their tongues in amazement.

They felt that.

Ever since Chen Mu joined the group, all they talked about were high-end subjects.

Tokisaki Kurumi: "Then..."

Before Tokisaki Kurumi could speak, Chen Mu interrupted her.

Chen Mu: "Although something like a Time Machine can be built, changing the past isn't something you can accomplish simply by building one and returning to the past. There are many factors involved."

Chen Mu: "The past is not so easily changed. Changing the past means that you must bear the entire altered future. If you do not possess sufficient strength to bear that future, then even if you return to the past, you will be unable to change it."

Chen Mu: "That is also why the more distant the past, the harder it is to change. The more distant the past, the more future you must bear."

Tokisaki Kurumi: "..."

Tokisaki Kurumi fell silent upon hearing this.

Chen Mu: "And even if you truly manage to change the past by sheer luck, in a sense, the things you changed do not mean they never happened.

Or perhaps the past you altered merely evolves into a completely new branch on the River of Time, while your original timeline remains there, unchanged."

Chen Mu: "Changing the past sounds simple, but how difficult it is to actually do."

Chen Mu spoke with feeling.

Tokisaki Kurumi remained silent for a long while before finally speaking.

Tokisaki Kurumi: "I know, but I still want to try."

Why Not Devour Demons?

Naturally, Tokisaki Kurumi could not give up.

As the Spirit of Time, how could she not know the difficulty of changing the past?

Chen Mu: "Alright. In that case, I suggest that you don't come to our world this time. Going to Kanae's world would be better."

Tokisaki Kurumi: "???"

Kochou Kanae: "Eh, eh, eh?!!"

Demon Slayer World.

Upon hearing this, Kochou Kanae's eyes widened, and she cried out directly.

She had originally been thinking.

If Tokisaki Kurumi went to Chen Mu's world this time.

Whether she should go along as well.

Yet how had the conversation somehow turned into Tokisaki Kurumi coming to her world?

Kochou Kanae's heart was filled with confusion.

And in the Date A Live World.

Tokisaki Kurumi was equally baffled upon hearing this.

Chen Mu: "Judging by your expressions, Kurumi, you still don't know that the demons in Kanae's world have very long lifespans, do you? With your abilities, Kanae's world is currently far more suitable for you than mine."

Tokisaki Kurumi: "What? The lifespans in Miss Butterfly's world are very long?!! @Kochou Kanae."

Hearing this, Tokisaki Kurumi's face filled with shock, and she could not help asking.

This was truly the first time she had learned of it.

She had originally thought.

That the so-called demons of the Demon Slayer World.

Were merely man-eating beings like humans, only with some special abilities.

As the Spirit of Time.

Every time Tokisaki Kurumi used her powers, she had to consume her own lifespan.

And to replenish that lifespan.

She needed to devour and absorb other people's time.

If she had known that the demons in the Demon Slayer World all had such long lifespans, Tokisaki Kurumi would never have let the Demon Slayer World slip away.

Kochou Kanae: "Y-yes. Muzan Kibutsuji has already lived for a thousand years."

Tokisaki Kurumi: "!!!"

A thousand years?!!

Tokisaki Kurumi found it unbelievable. That had to be equivalent to several hundred ordinary people, right?

And from the looks of it.

Muzan Kibutsuji's lifespan extended far beyond a mere thousand years.

Chen Mu: "Sigh, I really don't know what you all chat about in the group every day. You somehow still don't know something like this."

The moment he said that.

Not only Kochou Kanae and Tokisaki Kurumi, but even Hoshino Ai and Gotoh Hitori could not help blushing.

What else could they chat about?

They basically just talked about how great Chen Mu was...

Tokisaki Kurumi had not asked because she did not know about the lifespans of the demons in the Demon Slayer World.
