Pirate: I have a Hollow living inside me

Nami innocently said, "Didn't you tell me to use lightning metallurgy?"

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

"Okay, okay, I'm trying to weaken the power of the lightning..."

'Snap~'

A small current 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 electric current! It's to remind you of the feeling of controlling gold when using remelting. What's the use of just discharging electricity?"

"But I don't know what to do. I've 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. Then use the magnetism to control the metal!"

"Why don't you just say it? Let the lightning flow... let it 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 didn't have that much control over the Thunder Fruit either.

After all, she was only fifteen years old, and had only eaten the Thunder Fruit a month or so ago...

"...I'm really not a user of the Rumble-Rumble Fruit. I don't know how to control the lightning of the Rumble-Rumble Fruit. This is 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 say it’s instinct, but instinct can be controlled through cultivation. Domineering aura is also a kind of instinct.”

'Om! '

Lox raised his hand.

A bright green orb of light appeared in his palm.

Rocks controlled the shape-changing Hollow Bullets, pointed at the transformed Hollow Bullets, and said to Nami, "Can you now control your lightning to undergo 'shape change'?"

“Enel’s Thunder Dragon is a ‘morphological change’ of lightning. Magnetism and magnetic fields can also be considered a kind of ‘morphological change’. I think you can study it in this direction.”

The conversion of electricity into magnetism should also be a kind of "change of form", right?

Fortunately, Rocks had read Naruto and knew about "nature change".

Perhaps this is a way to get Nami to try it out...

Yes, let's develop in the direction of "morphological changes"!

"Um... making lightning deform is a bit difficult for me..."

Nami looked at the emerald green orb in Rocks' hand that could change shape at will.

She chuckled and said, "It's not that I don't try, it's just that lightning is very violent and it doesn't listen to me!"

Rocks stared intently at Nami: "So what have you been doing these past few days? Weren't you practicing your abilities?"

"I am training, but I'm training how to escape in elemental form... uh... I mean, to make me faster..."

Nami felt embarrassed.

Then, patting his chest proudly, he said, "Right now, in terms of speed alone, you're no match for me."

"I can run from here to down here in an instant!"

"So, you mean to say..."

Rocks' face darkened: "You, a user of the Rumble-Rumble Fruit with immense destructive power, have spent all this time practicing how to escape at an even faster speed?"

Chapter 151 The Black-Winged Demon Awakens! The Black-Winged Demon's Phantom Flash!

"hey-hey……"

Nami gave a dry laugh.

She was just a minor and had little experience in combat.

Although he had eaten the Rumble-Rumble Fruit, his first thought was still to protect himself in battle...

How can I protect myself?

Of course, we should run away!

After the Rumble-Rumble Fruit was transformed into its elemental form, its speed was truly incredible; even Rocks couldn't catch up with it!

Locus: "..."

Giving you this fruit is such a waste!

"Alright, alright, I'll work hard to train with the Rumble-Rumble Fruit. I'm not just going to run away; I'm also trying to make the power of the Rumble-Rumble Fruit stronger!"

Seeing Rocks remain silent, Nami added, "Now I can unleash even stronger lightning!"

"In short, your attempt to train in 'morphological transformation' of lightning to develop the Supermagnetic Cannon technique relies heavily on magnetism..."

Rocks realized that Nami's development of the Super Magnetor was not going to be easy, so he decided not to continue guiding her.

Let Nami figure out how to convert lightning into magnetism on her own...

"Change the form of lightning to create a magnetic field and magnetically control steel."

Nami pondered for a moment and said, "Then you'll use magnetism to propel the steel launch, right? I'll work towards that!"

Rocks explained the directions to her.

If you don't work hard, you'll really be wasting this Thunder-Rain Fruit.

"Ask me if you have any questions. You can develop it on your own the rest of the time."

Rocks then thought of something else: "By the way, while developing the Rumble-Rumble Fruit, you can also try to train your Observation Haki."

"The unique nature of the Rumble-Rumble Fruit might allow you to master Observation Haki more quickly."

The Rumble-Rumble Fruit provides an "enhancement" to Observation Haki.

Having eaten the Rumble-Rumble Fruit, Nami might be able to master Observation Haki more easily than others.

This is something that needs to be reminded of to the other party.

"Is it domineering?"

Nami is no stranger to Haki now: "After I become an elemental, my senses seem to become very sharp."

"I can even vaguely sense the presence of people or creatures somewhere. Could this be the prototype of Observation Haki?"

"Probably so. Living creatures also have weak magnetic fields. Magnetism and electricity are inseparable. It's possible that you, a user of the Rumble-Rumble Fruit, can sense them."

Rocks nodded slightly: "Strengthen this sense, or rather, instinct of yours, that is Observation Haki."

Domineering aura is an instinct.

After Nami transforms into her elemental form, she can instinctively sense the magnetic field of a human body.

This must be the power of Observation Haki.

Nami simply couldn't control this instinct...

Upon hearing Rocks's reply, Nami exclaimed excitedly, "The Rumble-Rumble Fruit is truly powerful!"

Rocks was speechless: "Since you know you're powerful, don't just think about running away. Right now, even someone with a bounty of 100 million Berries wouldn't be a match for you."

Nami pointed at herself: "Am I that strong?"

"It's not that you're strong, it's that the Thunder-Rumble Fruit is strong."

Rocks cautioned, "However, don't rely solely on your abilities. You need to become stronger yourself to better unleash the power of the Rumble-Rumble Fruit."

Nami responded, "Oh."

"Well, it's almost lunchtime. Let's go eat first."

After checking the time, Rocks said to Nami, "After you finish eating, you can train on your own. As for Observation Haki, you can ask Izaki; he's better at it than I am."

Nami nodded: "Okay!"

……

Life on the Sky Island was not boring.

Everyone has their own things to do.

Kuina is practicing the sword techniques that Rocks taught her, and she is also training in Armament Haki, so her strength is increasing day by day.

Inspired by Rocks, Robin is also developing his own Devil Fruit, attempting to "open" another version of himself, and is also undergoing powerful training.

Nami has been less lazy lately and has been trying to develop the Super Electromagnetic Cannon to enhance her understanding of the Rumble-Rumble Fruit. Her progress isn't bad.

Although she is young, as the ship's doctor, she feels the need to study medicine and is learning from a doctor on Angel Island.

Issho acts as a teacher of Haki, instructing his companions on how to cultivate Haki. Some of the Sandia warriors are also interested in Haki, so he teaches them as well, displaying the demeanor of a blind teacher.

While Lox continued his daily training, he was also waiting for the day when the Blackwing Great Demon Void would awaken.

Lox was mentally prepared to face the Blackwing Great Void's "attack".

On the sixtieth day of settling on the Sky Island... the Blackwing Demon who had been "sleeping" inside Lox was awakened!

"Roar!!"

A roar that only Rocks could hear echoed in the mind's world and the space of consciousness.

The Blackwing Great Demon Void, which had been calmed down by being "pacified," opened its emerald green eyes at this moment.

'Buzzing...'

Its previously folded demonic wings were now spread open.

It's just the action of spreading its wings.

It's as if a powerful wind pressure is rising in this special space, sweeping in all directions.

"Is she awake?"

Having prepared himself mentally, Locke stayed alone in another area.

This is where the Golden Bell used to be.

Upon hearing the roar of the Blackwing Great Demon Void, Rox, who was sitting cross-legged, instantly sank into his mental world and consciousness space.

Locus saw the Black-Winged Great Demon Void roaring to the sky, his eyes narrowed slightly, but a smile appeared on his lips: "I've been waiting for you for a long time, Great Demon!"

"Roar!!"

The Blackwing Demon noticed Rocks's "gaze," turned its head, and met Rocks's gaze.

"Roar!"

The Blackwing Great Demon Void is a humanoid Void.

At that moment, a strange smile appeared on its face.

Then came a loud 'boom'.

A powerful force erupted from the Blackwing Great Demon Void, sweeping across the surrounding space.

It felt like a powerful pressure, or a burst of spiritual pressure.

This caused a slight tremor in this special space of consciousness...

'Boom boom boom...'

As the Blackwing Demon unleashed its illusory pressure, Rocks outside suddenly erupted with Conqueror's Haki.

It swept outwards from the center of his body.

The Blackwing Great Void and Rocks have an inseparable connection, and its power affects Rocks's main body.

At this moment, the Conqueror's Haki erupting from Rocks was even more eerie and sinister than usual.

At the same time, it is also more domineering and powerful.
