Assimilation of a Higher World

Before the naval soldiers rotated their ranks, Dom and Oboro took the opportunity to hide inside the building.

Then, Oboro summoned the system interface for the first time, and a card appeared in his hand.

Then it took effect on Dom.

The card transformed into a streak of light and shot into the One Piece's body.

Immediately, Dom's skin turned bright red, his eyes showed pain, and his limbs twitched.

He was in excruciating pain and tried to scream, but Oboro grabbed his throat and he couldn't make a sound.

Outside the window, naval soldiers were walking back and forth, but they did not notice the houses along the street.

They must have realized that someone was missing.

"Waaaaah..."

Dom looked so pained he was almost fainting.

Because his internal organs, including his skeletal system, were being forcibly altered... and his skin was constantly writhing.

The resource that Oboro gave him was one of the resources taken from the Demon Slayer world.

A Bloodline Card of an Upper Moon Demon.

As time passed, Dom's condition finally stabilized.

However, the situation is different from the demonization in the Demon Slayer world.

Although the skin color has changed somewhat, and two small horn-shaped bumps have appeared on the forehead, overall, it still maintains a human appearance, which is not obvious.

"Um."

Long released his grip on his throat, stroked his chin, and fell into deep thought.

He was intentionally using Dom as a guinea pig.

I want to see if the power of the Demon Slayer world can be applied to One Piece.

It's important to understand that these are two completely different worlds, and their power systems are naturally different as well... Just like his soul ability, as a high-level power source, he could use it at will in Demon Slayer, mainly because Demon Slayer has the concept of the soul. But after arriving in the One Piece world, he was 'rejected' by the power system of this world. Admittedly, the world's will is involved... but to use external power, a prerequisite is that this world has the setting of 'using this power'.

Because the limitations of the higher world are completely incomparable to those of the lower world.

Here, many methods... must be integrated into the system, which is called assimilation.

"Is it simply... that my physical abilities have improved?"

Long frowned slightly.

Before Dom could regain his senses, he grabbed the One Piece's arm and dragged him to the window, where the sunlight was shining through.

The light fell on the 'dying' Dom, but unlike in Demon Slayer, his flesh and blood were not scorched and melted or smoked.

"Interesting... The differences in background and setting mean that all external sources are instinctively suppressed by the world. The effect still exists, but it's weakened... It's similar to my soul ability. Or rather, it's restored to the true level of the ability... Demon Slayer is, after all, just a lower-level world. The 'value' it shows there can't match the world of One Piece... To put it simply, this level of 'power' is normal... If I went back to Hunter x Hunter, it would probably be the same."

"I thought I had elevated Demon Slayer to a higher level, but I didn't expect... the gap is still so big."

After he finished muttering, he saw Dom open his eyes, and his pupils returned to their clear state.

With his hands in his pockets and head down, he smiled and said, "Congratulations... you didn't die, you've successfully become stronger."

Dom propped himself up on his arms, realizing he was different from others, and stared blankly at his hands.

He was originally slender and weak, and his ability to maintain a foothold in the Flame Dragon Pirates relied on his agile fighting style. He never considered himself a power-type fighter, but now... he could feel explosive power within his flesh and blood. The most obvious transformation was in his senses... He could see clearly through the window to distant places, and his hearing could pick up the conversations of some Marine soldiers outside...

And the smell...

"My face..."

Dom touched his face, his throat bobbing.

In One Piece, all power and change must conform to this world.

There are many different races in One Piece, such as the Mink Tribe, the Longarm Tribe, the Snakeneck Tribe, the Fish-Men, the Giants, and so on.

This can be seen from the Totto Land created by Charlotte Linlin.

Now, with the help of the system's abilities and the resources he plundered in Demon Slayer, Oboro has personally created a new race in this world.

Demon Tribe.

A race that can be transformed from humans.

What did you do?

Dom realized what was happening and looked at Oboro.

The system, the cards... these things are invisible to outsiders.

"I only did a little something to you, don't worry about it... Just understand that you are stronger now, and you have more resources to survive." Long turned around and sat down in a chair, crossing his legs, and said.

"You are... a Devil Fruit user?"

Dom seemed to be deep in thought, as if he had made a connection to something.

"You could say that."

His words were vague and ambiguous.

Immediately afterwards, Dom opened one hand, and a weapon suddenly appeared out of nowhere in the air, shaped like a short dagger.

Judging from its casting technique and materials, it is clearly not an ordinary object.

Swoosh.

Long flung his hand and threw the weapon over.

Dom took it without hesitation.

"For you."

"Oboro said."

This is a Nichirin Sword.

But in the world of One Piece, it's probably not very useful; at most, it's just a bit more durable than a regular blade or weapon.

But it's still much better than the junk that Dom himself uses.

It can barely be considered a rare item.

Dom's eyes lit up with joy, but his mind was still reeling; he needed time to process everything.

He really wanted to ask what kind of Devil Fruit user Oboro was... but after thinking about it, he decided against it.

He and Long had only just met, and even if they were temporarily brought together by their circumstances, their relationship wasn't that good. How could he possibly reveal his secret?

For several days, they stayed inside the building, observing the naval movements on the street.

For Long, not eating or drinking for a long time is not a big problem... He can minimize the consumption of his bodily functions.

On the contrary, Dom couldn't bear it. Although he had become Demon Tribe and lost his natural enemy, 'sunlight,' in this world, he had also lost a lot of things... He no longer needed to devour flesh and blood, but the price was that, like other species, he needed to eat.

In addition, they cannot grow by devouring other animals.

These external forces were forced to make changes in order to integrate into the power system of the One Piece world.

"With your current strength, do you think you can take down the captain of the Flame Dragon Pirates?" Oboro asked.

"There is a certain chance..."

Dom replied.

He didn't know why Oboro asked that question.

"Um."

Long nodded slightly.

A judgment was made.

As expected of the world of One Piece, the natives of this world have truly extraordinary physical abilities and talents.

While Luffy and Ace are extremely rare, they are not uncommon.

Not to mention, there are even more perverted ones.

The captain of the Flame Dragon Pirates, with a bounty of 15 million.

Does the Upper Moon bloodline enhancement mean that Dom has grown to the level of One Piece with tens of millions of power?

Assimilation in the higher world is truly cruel.

Fortunately... he had enough cards in his system inventory.

"The navy has withdrawn."

Just then, Dom caught a glimpse of a large number of naval soldiers beginning to retreat outside the window, and his face lit up with joy.

We've finally made it through this ordeal safely.
