As the intense battle unfolds, both fighters unleash their most powerful techniques. The Shiki utilizes his Royal Prestige Earth Coiling, summoning massive lions imbued with Haki that relentlessly strike Arthur.
In response, Arthur channels the fury of Angry Thor, unleashing 300 million volts that shrink his body to ten meters. His normally blue and purple form now appears entirely purple due to the compression, creating a scorching heat wave around him.
With each movement, Arthur launches devastating attacks that crush the Haki-infused lions sent his way. Meanwhile, the Shiki, realizing that sheer numbers won't suffice, employs his renowned swords, Twenty-One Workers, enveloping them in Haki to counter Arthur's assault.
In turn, Arthur coats his three-pointed, two-edged knife with Armament Haki. The clash of their weapons creates a symphony of impacts, accompanied by flashes of thunder and dark golden light, wreaking havoc on their surroundings.
While the Shiki takes to the skies, Arthur utilizes electromagnetic fields to teleport, leading to brief aerial skirmishes followed by explosive separations, each exchange generating powerful shockwaves.
On the island, there are numerous residents, including merchants and various animals. The intense clash between Arthur and the Shiki has thrown these inhabitants into a state of panic.
The battleground between them not only affects the people and creatures but also alters the very sky above. It flickers with alternating blue, purple, and golden lights, periodically obscured by dust kicked up by their tumultuous combat. The air resonates with the shockwaves and vibrations, creating a chaotic scene akin to a major earthquake.
The relentless fighting drains both Arthur and the Shiki considerably. The Shiki's Conqueror's Haki suffers due to damage to his rudder, diminishing in duration and potency with each use.
Aware of their dwindling reserves, both combatants know they can't sustain this level of battle indefinitely. Arthur's 300 million volts, while formidable, has a brief usage window that weakens his overall abilities afterward.
The Shiki recognizes this vulnerability, realizing that their struggle will end with one of them unable to continue. They exchange powerful attacks, each pushing their limits in a desperate bid to overcome the other and avoid being defeated and buried on the island.
During their close-quarters combat, both Arthur and the Shiki constantly disrupted each other's attack patterns, searching for vulnerabilities using clever tactics that didn't drain too much energy.
Arthur pushed his limits, sensing that he was growing stronger with each exchange. He believed that he was nearing a breakthrough in his Devil Fruit abilities, possibly surpassing the 300 million volts limit he had reached. He speculated that the Thunder Fruit's potential could extend to billions of volts, comparable to the most powerful natural thunderstorms.
On the other hand, the Shiki found it increasingly challenging to wield Haki effectively due to his aging body and the damage to his rudder, a consequence of his past encounters with Roger. These factors combined to weaken his abilities significantly over time, leaving him questioning whether this battle would mark the end of his journey.
As the Shiki ceased using Haki, Arthur sensed a shift in momentum, feeling that victory might be within reach. However, understanding the importance of practical experience, Arthur made a strategic decision to forego using Haki as well, opting for a different approach to secure his victory.
In addition, Arthur's mastery of Haki paled in comparison to the Shiki's profound expertise. At this point, Arthur felt nearly exhausted.
"Lion Sea Breaking!" The Shiki's swordsmanship was unparalleled, even with his leg techniques proving immensely powerful.
"One hundred million volts, electric cutting!" Arthur's blade, radiating intense heat and light, cleaved through the Shiki's formidable attack, splitting the sea into two sections over a vast distance that would take time to mend.
"Jiehahahaha~ Boy, you're quite skilled!" Despite the grueling battle, the Shiki's ferocity remained undiminished, his attacks still potent.
Though aging, the Shiki's regal aura persisted, his pride and royal demeanor unyielding.
"Hmph, you're no slouch yourself, old lion!" Arthur's determination matched the Shiki's pride.
As a reborn fighter, Arthur refused to be overshadowed by the Shiki's reputation.
"Let's fight to the end! Shiki! We've both reached our limits, let's settle this!" Arthur resolved to end the conflict with one final strike, believing it would also break through his own barriers.
"Limit? Jiehahahahaha, you're premature! But if you seek death, I'll grant it!" The Shiki's laughter belied a seriousness in his gaze, acknowledging the gravity of their showdown.
After nearly five hours of relentless combat, both combatants pushed themselves to their absolute limits.
The outcome of their ultimate clash remained shrouded in uncertainty...
