I Don’t Want to Die as a Mob in My Second Life! ～A Story Where I Kept Training from Inside the Womb and Ended Up Being Mistaken for a Monster～ - Chapter 03: Time to Modify My Body!

Chapter 03: Time to Modify My Body!

“It’s been a while since I’ve been in the ‘Spiritual Domain.’”

Right now, I was in a white room.

This place is the Spiritual Domain—a world inside my own soul. Here, I can speak normally.

Well, my form is just a little floating soul orb, though.

I would have liked to return to my adult form while I’m here, but this avatar is the easiest for me to maintain. I shaped it when I was eight, and it’s kind of stuck that way ever since.

“Still… it’s as empty as ever.”

I looked around in my floaty state. It was an endless, white, mysterious space.

“I’ve heard that for some people, it’s filled with all kinds of stuff, or even covered in sludge…”

The Spiritual Domain reflects a person’s mental state.

Those filled with hope might see it overflowing with light or flames, while those consumed by anger or hatred might see a blood-soaked space.

As for people like me, who don’t have strong positive or negative emotions, it tends to be pretty plain and boring.

Haha. Even my soul is as unremarkable as a mob character.

“‘Entering the Spiritual Domain’—a training method where you dive into your own domain and strengthen your body from within. You can extend your energy channels, adjust how your muscles develop, or even speed up the cell division in injured areas.”

So, I figured I’d start strengthening myself while I’m still just a baby—but…

“Kanataaa~”

“Why are you guys here?”

Out of nowhere, a bunch of oddballs suddenly appeared in the space.

“[Doll], [Blank Shot], [Ittan-momen]. So, you guys followed me here?”

“Hi~!”

“‘Hi’ is not the right answer.”

Standing before me were three bizarre creatures.

“Hello.”

First, there’s the little gothic doll, [Doll]. The only female among them (probably).

“…”

Next is [Blank Shot], a fish with a metal tube for a head. Its mouth is always open, but it never says a word.

“Can I tie you up?”

And then there’s [Ittan-momen], which looks like a towel blown away by the wind. It’s obsessed with bondage, constantly asking if it can tie something up. And the answer is no.

These three were my partners, the Conceptual Spirit trio from my previous life.

“You guys are idiots, you know that? Did you miss your chance to escape?”

When a Conceptual Spirit’s wavelength matches a Reisoushi’s, it’s called a “Possessed Spirit,” and it can enter the Reisoushi’s Spiritual Domain.

But if the Reisoushi suffers a status ailment or dies, the Possessed Spirit takes the same damage.

“I told you to get out of here already…”

It’s lucky that we got hit by [Regression] instead. But what would you have done if I had actually died?

No way they want to die with me… They’re always underestimating me, after all.

“Sigh. Lower-rank Conceptual Spirits with barely any intelligence are really hopeless. Listen up, okay? Spirits like you—and a mob spirit like me—should just run away when things get dangerous…”

“Hello!” “…” “Can I tie you up?”

They hit me—[Doll] punched me, [Blank Shot] blasted me with a shockwave, and [Ittan-momen] smacked me.

What’s your problem, guys!?

“Damn it, I don’t get it. It’d be nice if you had enough intelligence for a proper conversation…”

These guys seriously make no sense. They nibble on my hair, try to crawl into my mouth—I’ve had a hard time dealing with them in my past life.

“Ugh, fine. Just stay put, alright? I’m about to start training to control my body. I’m doing this so I never die again. So go hang out in the corner.”

“No.”

“Yes, you will… Fine, I promise I’ll make you some cake once I can move my body again, so just behave, okay?”

With that, the spirits cheered in their usual emotionless way.

What a strange bunch. Conceptual Spirits are supposed to sustain themselves primarily on spirit energy; physical food shouldn’t even fill them up.

“Well, whatever. Time to start my training.”

I decided to ignore the trio of dummies.

I focused on visualizing my physical body within my soul.

The flow of blood that I grasped when entering the Spiritual Domain. The network of veins and arteries. The shape of the organs where the blood flows.

Humans are like wire dolls made of blood vessels. By picturing even the capillaries running through muscles and skin, I could see the shape of my body more clearly.

And then—

“Visualization complete. Projecting body diagram (Fatal Open).”

As I said those words, the image of a baby’s body appeared like a window in the white room.

Along with it, a translucent mouse and keyboard appeared in front of me.

“Alright, I’m ready. Time to start the ‘Spiritual Body Modification’ training.”

This is the kind of training where you manipulate yourself from within the Spiritual Domain.

To put it simply, it’s like playing with clay or drawing. Or you could call it character editing.

From this space that is my soul, I adjust the visualized body diagram—adding details, using the mouse to drag and tweak parts, shaping the body into my ideal form.

“Back in the day, people said they’d see a brush and paper appear in front of them. But since I like online games, I get a PC setup instead.”

Though, it’s not like I can edit things as freely as in a game.

It’s more about giving commands to my body’s DNA to make small changes, like creating a bump or two.

Just small adjustments, but still…

“…If I use ‘Spiritual Body Modification’ on a fetal body, just how much will it actually accept…?”

This technique is meant to adjust my body. Normally, if I did this at an age when my organs and bones were fully formed, the changes would be minimal at best.

But right now, I’m a fetus, just three months away from being born. My weight is around 1,000 to 1,800 grams… still an unfinished human in many ways.

So, how much can I actually change?

“Small~”

[Doll] commented as she looked at my baby form.

“Yeah, it’s small, alright. That’s me before I’m born.”

“Small… down there. Make it bigger.”

“H-Hey!?”

[Doll] jumped onto the mouse, right-clicked the part of the baby diagram where, well, you know, and dragged it back with a big pull—

“Streeetch!”

“Whoa—!? Now it looks like a pillar!”

Stop, you idiot! If I end up like this, I’ll definitely get a stupid nickname like ‘Pillar Boy’ or something!

“Ugh, I’ll put it back… okay, there!”

I used my mind to move the mouse and adjusted it back.

Although, I decided to leave it just a little bit bigger… you know, just in case.

“Phew, that was close. What would’ve happened if I actually grew like that… wait a second.”

That’s when I realized something.

“Why was it even possible to stretch it that much…!?”

If I try to make an impossible change, my soul usually puts a stopper on it.

It’s like the “DNA on the ground” sends a complaint, saying, “Sorry, but this is as far as you can go,” so I can only make small adjustments.

For example, if I try to give myself a tail, the mouse stops pulling when just a little bump appears on my skin.

And yet—

“I see… it’s because my current self is still incomplete as a human. That’s why I can make some pretty extreme changes…!”

This… this is starting to get interesting.

Right now, I might even be able to change things like my facial features or hair color.

“My weight is still about half of what it will be right before birth. That means I’ve got around 2,000 grams to play with—enough to reinforce my skeleton and muscles…!?”

Ohhh, this means I might be able to come into my second life much stronger than before.

The strength of the body is crucial. Not only does it make me less likely to die in battle, but as the saying goes, “A healthy soul resides in a healthy body.” A stronger body means a stronger soul, which in turn boosts my spiritual power.

And if I start laying down spiritual pathways now, turning them into channels for generating extra spirit energy…

“I might even be able to fight that Meat Angel…!”

Suddenly, a sense of hope filled me.

And this discovery… I owe it to [Doll].

“Thanks, [Doll]. You might have just helped me change my fate!”

“Because, I made it bigger?”

“…”

And just like that, I was brought back to reality.

I really didn’t want to change my fate with that particular adjustment…

[Tips]

Spiritual Domain: A space within one’s soul. The appearance of this space changes based on the individual’s personality.

By focusing on the heartbeat—the pulse of life—and tracing it backward through blood flow, red blood cells, stem cells, and bone marrow, one can reach the essence of their soul and access this space.

It serves as a control room for one’s being, allowing commands to be sent to the body’s cells.

Reaching this space is known as ‘Entering the Spiritual Domain,’ marking the start of a Reisoushi’s journey.

Spiritual Body Modification: Training that begins upon entering the Spiritual Domain. It involves altering or adjusting a visualized diagram of the body, changing it from the inside out through the soul.

However, the effectiveness decreases as the body reaches maturity, and changes that are impossible due to DNA constraints cannot be made. Additionally, the soul may automatically prevent any alterations that could threaten the body’s survival.

But if it’s a fetus…?
