On the bow of the Freedom.
Kong Tai had already dismounted the railing, leaning against it with a smile, looking at Kuina.
That's right, he had obtained Enel's Goro Goro no Mi.
His spatial domain was beyond the reach of other abilities.
To be within his domain was akin to being in another world.
So after killing Enel, the fruit he had prepared in advance came into play.
He had completely sealed his spatial domain, which meant that after the Goro Goro no Mi's ability's host, Enel, died, it had nowhere else to go but into the fruit he had prepared.
These fruits were something he had anticipated and prepared when he thought about going to Skypiea and facing Enel, back on Carter Island.
There were all sorts of fruits.
In truth, he hadn't been sure if it would succeed initially, as he had no understanding of the principles behind Devil Fruit transformations.
He had tried it out of curiosity. Since his spatial domain could completely isolate him from the world, he didn't believe the fruit's ability could escape even if it was completely cut off.
If it could still escape, it would prove that the fruit's ability, or perhaps the person who created it, was something he couldn't possibly imagine.
Perhaps it was truly a demon, a creature from myth.
Only such an existence could ignore the isolation of his spatial domain.
Fortunately, he had succeeded.
This proved that this thing wasn't created by some true god or demon, but rather something he couldn't yet comprehend.
He believed that as he explored the world and grew stronger, these secrets would eventually hold no mystery for him.
Perhaps, this thing was created by the people of this world with technology from an alien civilization!
After all, there were too many unexplainable things in this world.
Hmm...
There was another possibility, that a race with superpowers originally lived on this planet, but at some point, whether by other beings, alien civilizations, or natural disasters, they were wiped out.
And the superpower factors within their bodies, the Devil Factors, were passed down through some unknown method.
This resulted in the creation of Devil Fruits.
He shook his head, this was just one of his conjectures. He didn't care about the history of the World Government; he only cared about Kuina and his companions.
After all, they had all eaten Devil Fruits.
Kuina had originally been hesitant to eat a Devil Fruit, but when faced with this god-tier Devil Fruit, perhaps it was fate, she showed no resistance and felt a deep attraction.
Finally, considering that her growth had stagnated, she ate the fruit.
She feared that her strength would be permanently fixed at this level, as she could already feel her body reaching its limit.
Further improvement would likely be minimal.
Even with Kong Tai's spatial domain and Ah Hua's robot, a person's body has its limits. Not everyone possessed the top-tier physique of Monkey D. Luffy and Roronoa Zoro, nor the monstrous capabilities of Kong Tai.
Everyone who stood at the pinnacle of this world was an absolute genius and a monster, not someone who could reach such heights through effort alone; there was no doubt about this.
Because effort could only determine a person's lower limit, while talent truly defined the ceiling of what one could achieve.
Therefore, even though Kuina had cultivated Haki to the level of Ryuo, her body's limitations meant that her total Haki capacity could not match that of true monsters, much like the samurai of Wano Country who could use Ryuo.
Even if they could injure Kaido, due to their own power and limited Haki, they could at most inflict superficial wounds.
Of course, Kuina's achievements, no matter how modest, were still beyond those of the samurai of Wano Country.
She simply couldn't compare to peak powerhouses. She could still contend with ordinary great pirates, Marine Vice Admirals, even Admiral candidates, or the Sweet Commanders and Calamities.
But after eating the Goro Goro no Mi, things were different.
It couldn't be denied that Enel was a genius, but he was too lazy and too arrogant.
The power of lightning was immense; it wasn't merely a Logia-type fruit. It could be used for body refinement and to break through the shackles of talent.
So after Kuina ate the fruit, Kong Tai trained her in his spatial domain for two days.
One aspect was to develop the application of lightning.
The other was to find a way for Kuina to use the power of lightning for body refinement.
It was going well.
With Kong Tai's spatial domain, Kuina quickly familiarized herself with the power of lightning and could use electric currents to stimulate her cells for body refinement.
As for offensive techniques.
The moment he saw lightning, Kong Tai thought of someone.
That would be Mikoto Misaka from A Certain Magical Index, a master of electricity.
In truth, the damage inflicted by pure lightning wasn't as high as one might imagine in this world.
This could be seen from the fact that Enel's lightning couldn't kill people.
Due to their differing physiques, the people in this world had high body resistance. Despite the high voltage and temperature of lightning, much of it was canceled out when it struck trained individuals, especially the strong.
This resulted in pure lightning not being able to deliver satisfactory results.
Thus, another offensive method emerged: "electromagnetism."
In fact, Enel also used electromagnetic force, a type of electromagnetic ability called "electromagnetic waves."
His ability to increase the breadth and depth of his Observation Haki was through electromagnetic waves.
If he had thought a little more, he could have even developed electromagnetic attacks.
In fact, Kizaru was right, speed is power.
When an object reaches a certain speed limit, the energy produced is immense.
Lightning's extremely high voltage can break down air, forming plasma, which then creates a high-speed guide rail. On this rail, an object can accelerate infinitely, ignoring resistance.
The principle is similar to that of a railgun.
As for what a railgun is, he didn't know.
Such specialized knowledge was something he had only learned a little about in his previous life by watching A Certain Magical Index and hearing about countries researching railguns.
Even without knowing the specific details, a bit of superficial knowledge was enough, and he also knew that this method was more powerful than single lightning strikes.
Therefore, the offensive techniques developed by Kuina after obtaining the fruit were fundamentally different from Enel's.
Of course, if in the end, the fruit's discharge ability could exceed 1 billion, 2 billion, or even tens of billions of volts, that would be another matter.
Lightning of that voltage would truly be on par with natural disasters, and at that point, regardless of the body resistance of the people in this world, they would be reduced to ashes!
This was the power of nature, the power of the God of Nature.
It was something that insignificant humans could never resist.
