One Piece: With Sign-in System

The Second Day…

Ron returned to Dorry's side, ready for another sparring session. The clash of their strength-filled blows echoed across the island as they engaged in an exhilarating and intense fight.

The Third Day…

Ron faced Brogy once again, their duel just as fierce and demanding as before.

The Fourth Day..

Another match with Dorry pushed Ron to his limits. Meanwhile, Enzo, Robin, and Conis immersed themselves in special training and physical conditioning, honing their abilities under Ron's guidance.

Ron, however, was entirely focused on battling the two Giants. These bouts of pure strength against evenly matched opponents caused his massive life energy to surge through his body, relentlessly refining and enhancing his physique. The results were astounding as his physical capabilities advanced at a breakneck pace.

Four Months Later…

Time flew by. Four months of relentless training transformed Ron's power significantly. His vitality value soared to an astonishing 1,800 points. His raw, one-arm strength alone now exceeded 30,000 kilograms, not to mention his speed, endurance, and defensive capabilities. His blood energy technique, Essence of Strength, progressed to Level 2, granting him a 20% strength boost upon activation.

The training also brought remarkable progress for Enzo, Robin, and Conis. Enzo achieved extraordinary physical improvement. His vitality surged, and under Ron's careful guidance, he successfully mastered two of the Six Powers—Shave and Tempest Kick. Though his Armament Haki showed promise, Observation Haki remained elusive. Nevertheless, his current strength allowed him to defeat a six-meter-tall Tyrant Dragon single-handedly.

Robin further developed her Flower-Flower Fruit abilities, now able to sprout up to eighty arms, greatly expanding her combat and support capabilities. Her skills became more versatile and dangerous than ever.

However, the most impressive progress came from Conis. Her mastery over the Metal-Metal Fruit had reached new heights. Her Blade Dance technique advanced from three steel blades to seven, her speed doubling in the process. Her control over the blades became more fluid and precise. Moreover, she expanded her range of metal manipulation from a radius of ten meters to a staggering sixty meters, although this extended range significantly drained her stamina.

After testing their progress one day, Ron nodded in satisfaction. "It's about time we left this place."

"We're finally leaving?" Conis and Robin both sighed with relief.

…

The next day, after bidding farewell to Dorry and Brogy, Ron and his crew boarded their ship and followed the river toward the open sea. As they reached the ocean, the waters ahead began to churn violently.

"What's going on?" Robin adjusted her cowboy hat, her sharp eyes narrowing at the disturbance.

Conis squinted at the sight, her expression turning to shock. "What… What is that?!"

From the ocean emerged an Island Eater Goldfish, its colossal body as large as an island. It loomed over their ship, opening its enormous mouth wide.

Conis, Robin, and Enzo froze in terror.

"What… what is that?!"

"What do we do, Captain?" Conis turned to Ron, desperation in her eyes.

Before Ron could answer, a loud voice boomed across the sea.

"That's an Island Eater Goldfish. It has devoured every ship that's tried to leave this island in the past."

The crew turned toward the source of the voice. Standing on either side of the sea exit were the towering figures of Dorry and Brogy, clad in enormous gray cloaks and holding their weapons.

Dorry smirked at Brogy. "For my friend Ron's sake, I'll join forces with you this time. Don't drag me down, you old fool."

Brogy snorted. "Hmph. Speak for yourself!"

"Wahaha! That's my line!" Brogy laughed heartily and turned toward Robin and the others. "Just keep sailing forward! We'll clear the way for you!"

Robin was about to express her gratitude when Ron's calm voice interrupted her.

"Thank you, but… there's no need."

With a sudden swish, Ron vanished from the ship's deck, reappearing midair above the ocean, directly facing the goldfish's massive gaping mouth. His body was enveloped in fiery red steam, waves of energy rippling outward.

In his right hand appeared a black blade emanating an intense crimson sword aura.

"Armament Haki: Hardening." Ron's voice was calm yet resolute.

The black blade, Shusui, gleamed with a deep violet-black glow, its edge flickering with sinister brilliance. The air around it seemed to split apart under its force. Under the astonished gazes of Dorry and Brogy, Ron raised Shusui high. A swordsman's overwhelming aura surged skyward, whipping up fierce winds. The sea below began to part even before the blade descended.

"Sun Breathing: Thirteenth Form: Raging Sun."

 A massive, pitch-black flying slash, wrapped in scorching crimson flames, tore through the ocean and the goldfish alike. The colossal creature was cleaved clean in two. Its massive halves crashed into the sea, sending towering waves surging in all directions.

The Traveler was propelled forward by the waves, quickly leaving the danger behind.

"Dorry, Brogy, farewell!"

Standing midair with Shusui in hand, Ron exhaled softly and turned back to the two giants, still frozen in shock. He waved with a grin before stepping onto the air with Moonwalk, shooting forward like an arrow to rejoin the ship.

In no time, the vessel disappeared into the horizon.

Only then did Dorry and Brogy snap out of their daze. The two exchanged glances.

"Looks like he didn't need our help at all," Dorry admitted.

Brogy nodded. "That Ron… I can't believe he was hiding such overwhelming power."

"Or maybe we just weren't strong enough to push him to go all out. That guy… he really is a monster."

They shook their heads as they began walking back.

"Oh, by the way, did that slash just now carry a trace of Conqueror's Haki?" Dorry asked.

"Did it? I didn't really feel it. But if it were Ron, it wouldn't be surprising if he awakened Conqueror's Haki."

"True enough. After all, he's a monster capable of matching the strength of a Giant warrior… what else wouldn't he be capable of?"
