Elsewhere, Luffy's fist was still extended from his punch.
After the enormous golden ball slammed into Enel, it sent the self-proclaimed god flying backward.
Enel crashed into the Golden Bell, then fell to the ground from the recoil, his chest heaving, his face deathly pale, and blood covering the corners of his mouth.
He had not turned into lightning, disappeared, or effortlessly evaded the attack as he had before.
After landing, Luffy tilted his head and looked at his fist, then at Enel lying on the ground.
"Huh?"
His face was full of confusion.
"Why didn't he turn into lightning just now?"
Zoro frowned.
Usopp's eyes were practically popping out of his head.
"Hey, hey, hey! Doesn't that guy turn into lightning? Couldn't we not hit him before? What just happened?"
Nami was stunned, too.
She had seen Enel's terrifying power firsthand. The power to call down lightning with a casual gesture hardly seemed like something humans could fight.
Yet now, Luffy had knocked this monster flat with a single punch.
It was not because of a counter or luck. Rather, Enel's ability seemed to have suddenly been drained away by something.
Nami was just about to speak when a faint tap suddenly sounded beside her.
She looked down.
At some point, a scroll had appeared on the ground.
Beside it lay a pale blue crystal.
The crystal was only the size of a thumb, with faint blue light flowing inside, as though a mass of energy had been sealed within it.
"What's this?"
Nami instinctively stepped back half a pace.
Usopp immediately jumped in fright.
"Don't touch it! Something that drops out of nowhere like this looks dangerous no matter how you look at it!"
"But it seems..."
Nami stared at the crystal, her heartbeat suddenly quickening.
It was not fear, but a very strange attraction.
As though that thing was meant for her to pick up.
Nami gritted her teeth and reached out to pick up the scroll anyway.
The instant the scroll touched her hand, the writing on its surface actually began to writhe.
The unfamiliar symbols changed little by little, finally becoming something she could understand.
"Chakra... Refinement Technique?"
Nami read the words softly, her face full of confusion.
But before she could open it for a closer look, the pale blue crystal suddenly flew up and pressed itself against her palm.
"Ah!"
Nami startled, but it was already too late to shake it off.
The crystal turned into a wisp of blue light and slipped into her body through her palm.
Usopp's face went pale.
"Nami! Are you okay? Don't scare me!"
Nami stood in place, her body stiff for several seconds.
Then a flood of unfamiliar information poured into her mind.
Physical energy and mental energy combined to refine a power called chakra.
The contents of the scroll were no longer merely words, but had become a complete training method.
She could even clearly feel a faint seed of energy that had appeared within her body.
The sensation was faint, but unmistakably real.
Nami's breathing suddenly quickened.
She raised her hand and looked at her palm, the panic on her face slowly turning into delighted surprise.
"This thing... can make me stronger?"
Usopp froze.
"Stronger?"
Nami gripped the scroll tightly.
She knew perfectly well how dangerous the sea was.
Arlong, Crocodile, Enel-each was more outrageous than the last.
Her navigation skills could lead everyone in the right direction, but when they encountered monsters like these, she often could only hide and wait for others to risk their lives.
If she could train, too.
If she could possess power that truly belonged to her.
Then the next time danger struck, she would not have to pin her hopes on someone else every single time.
Nami looked at the scroll, unable to stop the corners of her mouth from rising.
"This is a real treasure."
At the same time.
Inside the little house in Konoha, Fang Xu saw everything that happened on Skypiea.
It was as though he stood outside the image.
The Golden Bell, Luffy, Enel, Nami, and the scroll of the Chakra Refinement Technique that had dropped out of thin air were all perfectly clear.
What concerned him most was not Luffy's punch, but the items he had exchanged.
"What I gave away was a mass of chakra."
Fang Xu stared at the blue light disappearing into Nami's palm, his brows furrowing.
"How did it turn into a crystal?"
There was also that handwritten copy.
He had clearly used Konoha's writing, and the contents were a method for refining chakra from the Naruto World.
Yet once it reached Nami's hands, the writing on the scroll had actually transformed on its own into something she could understand.
This was definitely no ordinary exchange.
"Could the exchange talent give the traded items special treatment?"
Fang Xu's heart pounded.
If that was true, its value was immense.
What he had sent over was not merely chakra and a scroll, but a key to supernatural power that his talent had transformed into something the other world could absorb, understand, and practice.
He had initially worried that, with different worlds operating under different rules, the chakra system might not adapt well after being sent over.
Now it seemed his talent was even more powerful than he had imagined.
"I won't lose out on this first exchange."
Just as the thought occurred to Fang Xu, the image of the myriad worlds before him began to fade.
The bell on Skypiea was still ringing, but the image dispersed bit by bit.
The next second, a weight settled into his palm.
A blue fruit appeared out of thin air.
Its surface was covered in spiral patterns, with fine traces of lightning between them, like miniature bolts of lightning clinging to the peel.
Fang Xu's breath caught for half a beat.
"The Rumble-Rumble Fruit..."
He recognized it at a glance.
This was no ordinary Devil Fruit.
This was the Rumble-Rumble Fruit, which ranked among the very best even within the Logia category.
Speed, destructive power, elementalization, ranged attacks-all maxed out.
If he had previously been nothing more than a civilian Ninja Academy student with relatively little chakra, then this fruit was something that could take him straight to the top in a single bound.
At the same time, notifications appeared in his mind.
[Exchange complete.] [Obtained: Rumble-Rumble Fruit.] [Notice: The talent has automatically removed this fruit's original weaknesses.] [Notice: Enel's lifetime of insights into developing the fruit's abilities has been included.]
Fang Xu's fingers abruptly tightened.
Its original weaknesses had been removed!
In other words, the Devil Fruit's vulnerability to seawater, seastone, and similar problems were all gone.
This was no longer simply the Rumble-Rumble Fruit.
This was the Perfected Rumble-Rumble Fruit!
Even more outrageous, it came with Enel's lifetime of insights into developing its abilities.
Although Enel was arrogant beyond measure, his development of the Rumble-Rumble Fruit was certainly impressive.
Thunder Bird, Thunder Beast, Thunder Dragon, El Thor, Raigo, elementalization, lightning movement, electrical heating, metal smelting...
These were not things someone would automatically master just by obtaining the fruit.
An ordinary person who ate the Rumble-Rumble Fruit would, at most, only know how to discharge electricity.
Developing the fruit to Enel's level required a great deal of time and combat experience.
Yet now, all that experience had been delivered to Fang Xu as well.
"What a huge win."
Fang Xu's throat went dry, and only those words remained in his mind.
Without hesitation, he opened his mouth and bit into it.
He had long since prepared himself for the Devil Fruit's awful taste.
But with his first bite, Fang Xu froze.
