Star Rail World: As a Researcher, I Joined the Chat Group

He would rather believe Chen Mu was the reincarnation of an Aeon than believe in science.

The technology of this world.

Chen Mu had found it incredibly strange for a long time.

Sometimes, he truly did not know what to say.

After bidding Himeko and the others farewell,

Chen Mu's reason was not merely an excuse.

At this moment, he truly had something in his hands that he desperately wanted to understand and study.

After arriving at his personal laboratory,

Chen Mu took out the item.

It was—

from the Demon Slayer World,

the blood of Upper Rank Two—Douma.

In the Demon Slayer World,

Breathing Techniques, Nichirin Blades—

to be honest, Chen Mu did not care much about any of them.

Compared to those things, he cared more about the existence of demons.

Of course,

he did not care about demons because of their strength.

In Chen Mu's eyes, the so-called strength of demons was nothing worth mentioning.

What he cared about was...

"Immortality."

Chen Mu murmured as he looked at the demon blood.

That was right.

What he cared about was not anything else, but the immortality of demons.

In the Star Rail World,

even the so-called Long-lived Species on the Xianzhou

could live for only a thousand years at most.

After a thousand years,

they would be plagued by the so-called Mara-struck condition, losing their sanity one after another, turning into monsters, and falling into endless suffering.

Yet Muzan Kibutsuji of the Demon Slayer World

was still lively and kicking after living for a thousand years, without a single problem.

If he had not been killed by the protagonist Tanjiro Kamado in the original story, no one knew how much longer he could have lived.

The two worlds differed vastly in strength, technology, and level.

Yet this was the result.

How absurd was that?

To be honest,

in Chen Mu's eyes,

the Star Rail World's

technology related to immortality had gone wildly astray.

Among the worlds he knew,

any world whose technology had developed to the level of the Star Rail World would not have beings constrained by lifespan.

Now that he had obtained demon blood from the Demon Slayer World, Chen Mu naturally had to study it thoroughly.

That had also been why he had researched Douma in the Demon Slayer World.

Chen Mu quickly got to work.

This was only a small study, so he did not need anyone else's help.

Although it was only Douma's blood rather than Muzan Kibutsuji's own blood,

that was nothing to Chen Mu.

Douma's blood was enough for him to deduce everything—to uncover the secret behind Muzan Kibutsuji's immortality.

It was like Kochou Kanae's Breathing Techniques back then.

As long as Chen Mu saw one type of Breathing Technique, he could roughly understand the form in which they existed.

He did not need to examine other Breathing Techniques for reference. He could infer the rest from one example and produce the most perfect answer.

In Chen Mu's view,

if someone needed to look through every Breathing Technique to reach that point, it meant they were mediocre to begin with.

At best, they were merely clever mediocrities.

As the research continued,

a look of astonishment gradually appeared on Chen Mu's face.

It was not because the research was too difficult.

It was because...

the research was far too easy.

There was none of the difficulty Chen Mu had anticipated. Instead, it was incredibly easy and smooth.

Before long,

using Douma's blood, Chen Mu thoroughly uncovered the secret of demon immortality

and improved and perfected it.

A Longevity Medicine

appeared in Chen Mu's hand.

Although this was inherently related to medicine,

and although Muzan Kibutsuji's immortality in the Demon Slayer World had also been the work of a single physician,

still—

out of reverence for immortality,

Chen Mu had never imagined it would be this simple!

A Longevity Medicine.

Had he truly refined one just like that?

However,

at that moment,

Chen Mu's expression suddenly changed as a sense of palpitations gripped his heart.

When he closed and opened his eyes,

Chen Mu seemed to have appeared in the middle of space.

This feeling...

was rather similar to when Stelle had encountered the Destruction Aeon.

Amid the boundless darkness,

a pleasant female voice rang out beside Chen Mu's ears.

"Once, twice, tiny shoots shall grow into towering trees. Sweet dew shall fall from their branches, dispelling illness and poison from you. Alas, alas—Xianzhou suffers the plague of longevity, allies turn against one another through slander, foreign foes ignite the flames of war, and the bones of soldiers scatter apart."

"There are many fools in this world who seek immortality. Will you be one of them?"

As the words fell,

golden light erupted before Chen Mu's eyes!

When Chen Mu opened his eyes,

what appeared before him was a deity of incomparable beauty!

A gentle glow radiated from her body.

Her beautiful appearance and exceptional bearing seemed capable of drawing anyone in.

"The Abundance Aeon—Yaoshi?!"

At the sight of that figure, Chen Mu's pupils constricted slightly. Naturally, he recognized the deity's identity.

The Abundance Aeon seemed to have heard Chen Mu's words.

She glanced at him, a faint smile appearing on her face.

Then she vanished.

Soon after,

at the Space Station,

Chen Mu abruptly woke up, his eyes filled with shock.

He could naturally guess

that creating the Longevity Medicine had drawn the Abundance Aeon Yaoshi's attention.

That was why the Abundance Aeon Yaoshi had specifically come to see him.

Looking at the Longevity Medicine in his hand, Chen Mu wore an expression somewhere between laughter and tears.

What... was this supposed to be?

How long had it even been?

The Aeons, the most powerful beings standing in the universe—

he had already met two of them in succession...

In a Law-Abiding Society, Why Would You Need a Blade?

But compared to the Destruction Aeon Nanook,

the Abundance Aeon Yaoshi was truly extremely beautiful.

Her beauty alone made her worthy of the title of deity.

Looking at the Longevity Medicine in his hand, Chen Mu thought with a laugh that was not quite a laugh.

Now he understood.

This time, he had caught Yaoshi's attention.

Just as Chen Mu was preparing to speak with Herta about it,

a notification came from the Chat Group

within his mind.

With a thought, Chen Mu entered the Chat Group, intending to first see what had happened.
