Pirate: I have a Hollow living inside me!

There's no rush...

……

For some time afterward.

The Blackwing Demon Adventurer Group stopped their adventures and settled down peacefully on the sky island...

However, the Grand Line below will not become peaceful because of the "disappearance" of the Blackwing Demon Adventurer's crew.

Although it wasn't as eventful as when the Blackwing Daimo Pirates were around.

However, quite a few incidents also occurred—

For example, "Fire Fist" Ace rejected the invitation to become a Shichibukai, his bounty increased, and he became a Supernova Pirate.

Furthermore, they caused quite a stir in the Sabaody Archipelago and have now entered the New World...

For example, Bucky Barnes, the Joker, became more widely known because of another incident.

The opponent recruited many subordinates, and the bounty increased again, making him a Supernova Pirate.

Even its title has been changed to "Qianliang Daohua", and it is currently one of the Navy's key targets.

Rumors are circulating on the high seas that the World Government and the Navy intend to invite Buggy, the "Thousand-Ryoo Transformation," to become one of the Seven Warlords of the Sea.

However, the news has not been confirmed, and the newspapers have not yet reported it.

The most noteworthy.

Of course, it's because another member joined the Seven Warlords of the Sea.

This man is the "tyrant" Bartholomew the Bear...

This sea is always full of incidents!

However, the lack of news about the Blackwing Demon Pirates for more than a month has puzzled many people.

Some people speculate whether the Blackwing Daima Pirates have been captured by the World Government and the Navy.

However, this conjecture was quickly rejected.

If the Blackwing Daima Pirates are captured by the World Government and the Navy, the Navy will definitely report it.

It's impossible that there wasn't a single word of it.

After all, the Blackwing Daimo Pirates are newcomers among newcomers, and they can't even be considered newcomers.

The title of supernova could be bestowed upon "Fire Fist" Ace and "Thousand Ryo Transformation" Buggy.

But no one would think that the term "supernova" could be applied to the "black-haired swordsman" Rocks...

Because the strength and threat posed by "Black-haired Swordsman" Rocks have exceeded the evaluation of a supernova.

But no matter what.

The disappearance of the Blackwing Demon Pirates is indeed something many people are discussing...

Even world governments and navies are paying close attention to this.

According to the intelligence they have gathered.

The Blackwing Daima Pirates finally appeared on a lawless island called Jaya Island in the first half of the Grand Line.

After that, the other party disappeared without a trace, and all clues about them were lost.

This is very unusual!

They suspected that the Blackwing Demon Pirates were plotting some grand conspiracy...

……

Sky Island.

Apayado.

The training area is located above the clouds on the island in the middle of a giant vine.

"The principle of the railgun is to convert lightning into magnetic force and use the magnetic force to propel the metal projectile out."

"What? You're asking how to convert it into magnetism? How would I know that? I'm not a user of the Rumble-Rumble Fruit!"

"And don't you know the basic scientific fact that electromagnetism and magnetism are inseparable?"

Rocks figured that after a month or two, Nami's understanding and control of the Rumble-Rumble Fruit should be pretty good...

So at this moment, he is instructing her on how to develop the Rumble-Rumble Fruit.

The first thing that came to Rocks' mind was naturally Misaka Mikoto's "Railgun"...

Enel was able to use the "radio waves" of the Rumble-Rumble Fruit to enhance the effects of his Observation Haki.

"Radio waves" are also known as "electromagnetic waves and electromagnetic forces".

The ability to use electromagnetic waves and electromagnetic force means that lightning can be converted into magnetic force.

After all, electromagnetism and magnetism are inseparable.

Therefore, the "Railgun" technique could not possibly be impossible to execute.

Perhaps... the Rumble-Rumble Fruit is a superior version of the Magnet-Magnet Fruit?

However, to Rocks's dismay, Nami claimed she didn't know how to convert lightning into magnetism...

"What do you mean by electromagnetism being inseparable? How would I know that!"

Nami was completely bewildered.

She really didn't understand: "Lightning is lightning, how can it be converted into magnetic force?"

"Doesn't the movement of lightning current generate a magnetic field?"

Lockes explained the principle of electromagnetism simply: "As long as the magnetic force is precisely controlled, it can be used to propel a projectile..."

Nami was still confused: "Make lightning flow to create a magnetic field? A magnetic... magnetic field?"

"I know about magnetism; the recording pointer needs to use magnetism, but how do you control this force?"

Locus: "..."

"You can do metallurgy, right?"

"Yes, didn't you see it all?"

"When you were doing metallurgy, weren't you able to change the form of gold? You could even control gold in certain ways. That's the application of magnetism, right?"

"Huh? Is...is that so?"

"Isn't that so?"

"is it?"

Locus's lips twitched: "..."

After thinking for a moment, Lockes offered a suggestion: "How about this, remember the feeling you get when you use lightning in metallurgy, and then try to see if you can control iron..."

Nami muttered to herself, "I can only give it a try. Actually, ability is a kind of instinct."

"You're also a Devil Fruit user, don't tell me you didn't know that..."

She genuinely didn't know the underlying principle.

Everything comes down to instinct.

Lightning metallurgy is the process of melting gold using lightning, which is done naturally.

This is the "basic application" of the Rumble-Rumble Fruit.

Just like the animal-type transformation or half-beast transformation, it's a natural instinct...

She couldn't explain it clearly.

'Crackling crackling...'

Nami picked up an iron sword and started trying it out.

However, the high-voltage lightning instantly melted the iron sword, turning it into molten iron that dripped to the ground...

Looking at the molten iron on the ground, Locus's face darkened: "Can't you reduce the intensity of the lightning?"

Nami looked innocent: "Didn't you tell me to use the lightning that's used in lightning metallurgy?"

"I'm telling you to control iron, not to melt it!"

"Okay, okay, I'll try to reduce the power of the lightning..."

'Snap~'

A small wisp of electricity pulsed from Nami's fingertips as she pointed to another iron sword: "Fly!"

Why doesn't it fly?

"Please, it's magnetism, it's magnetism! Not electricity! It's to help you remember the feeling of controlling gold when using lightning metallurgy, what's the use of just discharging electricity?"

"But I don't know what to do. I've already said it's an instinct, and I can't control it!"

"Let the lightning flow through your arm. When lightning flows through a conductor, it creates magnetism, and then you can use that magnetism to control metal!"

"Why don't you just say it directly? Let the lightning current move... flow..."

Nami still looked innocent: "So... how do I do it?"

It's not that she's stupid.

She is very smart.

I just can't quite understand what Lox said.

She doesn't have that precise control over the Rumble-Rumble Fruit either.

After all, she's only fifteen years old, and it's only been a month or so since she ate the Rumble-Rumble Fruit...

"...I'm really not a user of the Rumble-Rumble Fruit, and I don't know how to control the lightning of the Rumble-Rumble Fruit. That's something only you can do!"

Rocks felt powerless and melancholy: "The lightning of the Rumble-Rumble Fruit should also be a kind of 'energy,' and 'energy' can be controlled."

“You call it instinct, but instinct can be controlled through training. Domineering aura is also a kind of instinct.”

'Om! '
