Pirate: I have a Hollow living inside me!

Lox raised his hand.

A bright green orb of light appeared in his palm.

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

“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 considered a kind of "morphological change," right?

Fortunately, Rocks had seen Naruto and knew about "nature transformation".

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

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

"Um... transforming lightning is a bit difficult for me..."

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

She chuckled awkwardly, "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 indeed cultivating, but I'm cultivating elemental transformation to escape more... uh... I mean, to make myself 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 Cero!

"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 the battle...

How can I protect myself?

Of course, we should run away!

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

Locus: "..."

This fruit is such a waste!

"Alright, alright, I'll work hard to train with the Rumble-Rumble Fruit. I'm not just someone who runs 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, you should try to train your lightning to 'change its form' and develop the Railgun technique. Magnetism is the key..."

Rocks realized that it wouldn't be easy for Nami to develop the Railgun, so he decided not to continue guiding her.

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

"Change the shape of lightning to create a magnetic field and use magnetic force to control steel."

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

Rocks explained the directions to her.

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

"Ask me if you have any questions. Otherwise, you can develop it on your own."

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

"The unique properties 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 imposing?"

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

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

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

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

Dominance is an instinct.

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

This must be Observation Haki.

Nami simply couldn't control this instinct...

Upon hearing Rocks' answer, 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 Rumble-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 was practicing the sword techniques that Rocks had taught her, and she was also training in Armament Haki, so her strength was increasing day by day.

Inspired by Rocks, Robin is also developing her own Devil Fruit, attempting to "open" another version of herself, and is also training in Haki.

Nami has been less lazy lately and has been trying to develop a super railgun to enhance her use of the Rumble-Rumble Fruit. The progress is not 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.

Yixiao serves as the teacher of Haki, instructing his companions on how to cultivate Haki. At the same time, some Shandian warriors are also very interested in Haki, so he teaches them as well, showing the demeanor of a blind teacher.

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

Locus was mentally prepared to deal with the Blackwing Great Demon Void's "attack".

On the sixtieth day of settling on the Sky Island... the Black Winged Great Demon Void that had been "sleeping" within Lox awakened!

"Roar!!"

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

The Black-Winged Demon Lord, who had been calmed down by being "pacified," opened its emerald green eyes at this moment.

'Buzzing...'

Its previously folded demon wings now spread open.

It was merely the action of spreading its wings.

It was as if a powerful wind pressure surged in this special space, sweeping in all directions.

"Has he woken up?"

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

This is where the Golden Bell used to be.

Upon hearing the roar of the Blackwing Great Demon Void, Rocks, 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 Great Demon noticed Rocks's "gaze," turned its head, and met Rocks's gaze.

"Roar!"

The Blackwing Great Demon Hollow is a humanoid Hollow.

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

Then there was 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 perhaps a burst of spiritual pressure.

This special space of consciousness was even trembling slightly...

'Boom boom boom...'

As the Black Winged Demon Hollow unleashed its oppressive aura, Rocks outside the room suddenly erupted with Conqueror's Haki.

It swept outwards from the center of his body.

The Blackwing Great Demon Void and Rocks have an inseparable connection, and its power can affect Rocks's physical 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.
