She had once naively believed that the Admirals represented the pinnacle of combat power on these seas, entities beyond challenge.
But now, the brutal reality before her eyes jolted her awake, making her truly realize that a Yonko wielding three Devil Fruit abilities possessed power far beyond anything she had ever imagined.
And the mastermind behind all this was none other than the man standing before her!
Ron!
Robin's beautiful eyes trembled slightly, like a calm lake disturbed by a falling stone, ripples spreading across their surface.
In her heart, Ron's figure seemed to grow increasingly towering at this moment, resembling a distant, omnipotent deity radiating a brilliance too dazzling to behold!
Ron stood firmly behind Nami and Robin, his sword-like brows tightly knitted like two sharp blades crossing.
His gaze felt almost tangible as it sharply scanned the chaotic, flame-engulfed battlefield below.
Waves crashed violently against the ships, the roar of combat never ceasing.
Amidst this cacophony, he spoke with steady composure.
"Big Mom's strength is exactly as I predicted, but this battle is far from decided."
Hearing this, Nami quickly turned her head toward Ron, her lively eyes now filled with confusion.
"You mean... the Navy still has a chance to turn the tide?" she couldn't help asking, her voice somewhat faint against the howling sea wind.
Ron nodded slightly, his gaze remaining firmly locked on the battlefield without shifting for even a moment.
"Though Big Mom is terrifyingly powerful, her strength isn't flawless. While she possesses three Devil Fruit abilities and appears invincible, each use of her power drains her stamina multiple times over. Moreover, she must maintain high-intensity output of all three types of Haki, which places an even greater strain on her endurance."
As he spoke, Ron raised his hand to point toward Big Mom's massive black dragon form.
Though the Yonko still appeared majestic, closer observation revealed a slight sluggishness in her movements.
"Big Mom's stamina is depleting at an alarming rate. Furthermore, both Garp and Magellan are legendary figures renowned throughout the Navy—what they've shown so far isn't their full capability.
If they can grit their teeth and drag out the fight until Big Mom exhausts her stamina completely, the scales of this battle will gradually tip."
Ron paused briefly before continuing, "Additionally, though Akainu is currently being suppressed, he's no reckless fool who'd charge in blindly.
Ultimately, this battle boils down to a contest of stamina and endurance between all parties.
However, if Big Mom disregards her own depletion and focuses all her attacks on a single target, she might succeed in eliminating one particularly threatening opponent."
Robin stood quietly nearby, listening intently to Ron's analysis before nodding slightly, her eyes filled with agreement.
"Indeed, the outcome of this battle is far from certain. But when do we infiltrate the Impel down?" she asked softly, a trace of urgency in her tone.
"Now," Ron declared resolutely.
"Huh???"
Nami couldn't help but gasp, her face a mix of shock and confusion.
After all, the battle below was raging fiercely, and Big Mom's terrifying power was enough to make anyone's blood run cold.
Infiltrating at such a moment seemed far too reckless.
However, just as Garp, Magellan, and Akainu were locked in a fierce battle with Big Mom—with flames soaring into the sky, colossal waves churning, and the cacophony of explosions and battle cries echoing all around—Ron had already begun to move stealthily.
Standing tall amidst the clouds, his gaze was as calm and precise as a scanner, swiftly sweeping over the chaotic battlefield below.
In his mind, a detailed plan had already taken shape.
The current chaos of the battle was the perfect opportunity for their operation.
"Nami, Robin, are you ready?" Ron whispered urgently, his tone leaving no room for doubt.
Nami and Robin exchanged a glance before nodding firmly in unison.
Though their hearts still trembled at the sheer terror of Big Mom's power, their legs even feeling slightly weak, the thought of their comrades possibly in grave danger instantly hardened their resolve.
Ensuring their companions' safety was now their top priority.
Seeing that the two were prepared, Ron wasted no further words.
With a slight movement of his right hand, a faint glimmer flashed across the castle ring, like a shooting star streaking across the night sky—here and gone in an instant.
Simultaneously, Nami and Robin felt a flash of light before their eyes, and their bodies were uncontrollably drawn into the ring's space.
In the blink of an eye, their figures vanished without a trace.
Ron took a deep breath, steadying his nerves, then slowly raised his sword.
His eyes burned with intensity as he fixed his gaze on the direction of the Underwater Great Prison.
With a subtle exertion of his arm, an almost imperceptible sword aura shot from the tip of his blade.
The castle ring on Ron's hand seemed to come alive, clinging tightly to the sword aura.
After releasing the sword aura, Ron's figure also disappeared as he entered the castle.
The sword aura, like a venomous snake lurking in the shadows, shot silently and swiftly toward the entrance of the Underwater Great Prison.
Working in tandem, they raced toward the prison entrance at incredible speed, slipping through a narrow gap.
The entire process was utterly silent, as if seamlessly merging with the surrounding air.
Amid the already white-hot battlefield, it went completely unnoticed by anyone.
Impel Down, once an impregnable fortress that struck fear into the hearts of countless pirates, usually exuded an aura of chilling solemnity.
Now, however, it was enveloped in an unusually desolate atmosphere.
Due to Big Mom's sudden assault, the entire prison seemed to have been swept into the eye of a storm.
Nearly all the guards had been dispatched to the front lines like a tidal wave, leaving only the occasional glimpse of jailer beasts behind.
They dragged their heavy footsteps, patrolling back and forth through the empty corridor, each step seeming to tread upon the silent heartbeat.
The entire prison passage exuded a bone-chilling cold from its icy walls, as if recounting the cruelty that had once unfolded here.
The flickering dim lights swayed unsteadily like will-o'-the-wisps, barely illuminating this path full of unknowns, stretching and distorting the shadows of the three figures.
Ron's transformed sword energy passed effortlessly through the prison's heavy gates like an invisible specter.
Then, He emerged from the castle ring, quickly scanning his surroundings, not missing the slightest movement.
Only after confirming there was no danger did he gently wave his hand, releasing Nami and Robin from the ring.
"Is this... Impel Down?"
