One Piece: With Sign-in System

Conis and Robin were undergoing intense training to enhance their Devil Fruit abilities and combat skills.

Enzo, the Kung Fu Dugong, however, had a far more rigorous training regimen.

His special training included foundational strength, speed, stamina, endurance, perception, and vitality.

The so-called vitality training was perhaps the most brutal—he was thrown into a pack of ferocious Tyrannosaurs and forced to fight for survival. This method aimed to awaken his deepest potential, pushing the very limits of his vitality.

While training them, Ron also devoted time to familiarizing himself with and mastering the technique powered by vital energy—Essence of Strength.

This technique seemed to work by igniting the vitality within, transforming it into raw, unadulterated power.

The duration of its activation was tied to the amount of vitality available.

With Ron's current vitality reserves, he could sustain the technique for about ten minutes.

However, once the vitality was depleted, he would be unable to continue fighting.

But thanks to his mastery of the perfected Sun Breathing Technique, Ron could rapidly recover both stamina and vitality while fighting.

As a result, the duration of his Essence of Strength could easily surpass ten minutes.

Time flew by, and ten days passed in the blink of an eye.

On this day, several volcanoes scattered across the island began to erupt, though only on a small scale. This eruption served as the signal for Dorry and Brogy's next duel.

Brogy, who was drinking with Ron, heard the rumble and immediately stood up, grabbing the massive axe resting nearby.

"Ron, we'll drink again later. For now, I must go—my duel awaits."

With that, he hefted his enormous axe and strode away, each step shaking the ground beneath him.

The duel between Brogy, the Red Ogre, and Dorry, the Blue Ogre, had begun.

The entire island quaked under the impact of their colossal battle.

"It's starting…"

Robin and Conis, in the midst of training their Devil Fruit abilities, raised their heads to watch.

"The duel between those two giant warriors."

When the massive weapons in Dorry and Brogy's hands collided with all their might, the resulting sound and shockwaves rippled outward.

The sheer force of their clash spread in waves, shaking the island and rolling out to sea.

Beyond the shores of this ancient island, known as Little Garden, the ocean erupted into massive waves and fierce winds.

Standing atop the highest point of the island, Ron observed the epic battle between the two giants in the distance.

There was no finesse in their fight, no elaborate techniques—just raw strength clashing head-on.

Their movements were vast and unrestrained, their strikes pure and primal.

The fire in their eyes burned with an unyielding fighting spirit as they glared at each other. Each blow carried the weight of their honor and pride as warriors.

Every ounce of their strength was dedicated to securing victory in this clash of titans.

The sheer intensity of the duel was… utterly exhilarating!

Standing high above, his black hair whipping in the wind, Ron clenched his fists. A burning desire to fight surged within him, his battle intent roaring like a blaze.

He yearned to join the giants' battle, to pit his strength against theirs and experience the thrill of such pure combat.

But he didn't want to disrupt their duel.

Suppressing his urges, Ron sat down at the peak of the mountain. With a flick of his hand, he summoned the endless Wine Jug from the void and took several hearty swigs. It helped quell the raging heat within him.

Behind him, several active volcanoes roared, spewing smoke and molten rock.

Ahead of him, the two giant warriors clashed with unrelenting ferocity.

"This… this kind of scene must be incredibly rare, even in the vastness of the Grand Line."

Ron held the endless flask in one hand, taking deep gulps as he marveled at the magnificent spectacle before him.

Before long, the afternoon slipped away.

As dusk descended, the sun sank low on the horizon, painting the ancient island in hues of gold and amber.

Enzo, battered and bruised, dragged a freshly caught prey back to their base.

Robin and Conis finished their day's training and began preparing dinner, starting a fire to cook their meal.

Under the golden glow of twilight, Dorry and Brogy's duel continued.

Ron lay atop the mountain's summit, eyes closed, a faint smile playing on his lips as the mountain breeze swept over his face.

Peaceful. Relaxed.

The duel between Dorry and Brogy raged on for three days, with neither emerging as the victor.

When both giants finally returned to their camps, Ron used Moonwalk to appear mid-air before Brogy.

"Brogy, if you're willing, would you spar with me as well?"

"Ron?"

Brogy stared at Ron in disbelief when he heard the challenge.

"Fight you?"

A burst of laughter escaped him. "Wahaha! Don't joke around, kid! With your tiny frame, you couldn't even handle a single strike from me!"

"I wouldn't be so sure about that," Ron replied with a calm smile.

The next moment, an intense and fiery crimson steam erupted from Ron's body, and his jet-black hair stood on end as if ignited by the sheer energy within. His blood seemed to boil.

With the blood-colored aura swirling around him, Ron vanished in a flash, reappearing in front of Brogy. Gathering immense power into his fist, he delivered a punch aimed directly at Brogy's enormous shield.

Bang!

A deep, resounding boom echoed through the air as an overwhelming force surged through Brogy's shield, traveling up his arm and causing his massive body to stagger backward two steps.

"This...!?"

Brogy's eyes widened in astonishment.

"Well? Does this qualify me to spar with you?"

Hovering in midair, Ron stood with his black hair flowing in the wind, his body radiating blood-red steam. He looked at Brogy with a confident grin.

For a moment, Brogy stared at him before breaking into a grin of his own, a booming laugh escaping his lips.

"Interesting! Alright then, let's see what you've got! Don't blame me if you end up dead, though!"

Lifting his massive axe, Brogy swung it down with incredible force. The air itself seemed to shatter, the sheer power of the swing creating visible shockwaves that rippled outward.

"Armament Haki: Hardening!"

Ron's fists turned a pitch-black hue, gleaming like steel, as he raised one to meet the descending axe.

Boom!

The clash sent shockwaves in all directions. The ground quaked, and the air roared from the impact.

Outside a wooden hut nestled in the forest, Conis paused her Devil Fruit training as the sounds of the battle reached her ears. She sighed with a hint of exasperation.

"They're fighting again?"

Robin chuckled softly. "Giant warriors truly live up to their reputation. They're as battle-hungry as the stories say."

The island echoed with the continuous sound of roaring air and clashing forces.

On the other side of the island, Dorry, surrounded by towering trees, furrowed his brow in curiosity.

"What's going on?"

"I thought the fight was on pause?"

"What's Brogy up to now, causing such a ruckus again?"

Intrigued, Dorry began making his way toward the source of the commotion.

As he approached, he caught sight of Brogy, wielding his massive shield and axe, locked in combat with a young outsider who fought barehanded.

"This is…?"

Dorry's expression was filled with confusion.

He then noticed the outsider—a black-haired youth enveloped in searing, blood-red steam—using pitch-black fists to clash head-on with Brogy's colossal axe.

Bang!

The black-haired youth was sent crashing to the ground with immense force, creating a massive crater as the earth cracked and caved beneath him.

Yet, even Brogy's massive frame staggered backward a step or two from the force of the collision.

Seeing this, Dorry's eyes narrowed sharply.

He knew all too well the extent of Brogy's strength.

And yet, this outsider—this small, young figure—had managed to force Brogy back?

The ground trembled once more.

A streak of blood-red light shot out of the shattered ground, hurtling skyward with incredible speed.

The black-haired boy emerged unscathed, his body a blur as he surged forward, landing another devastating punch on Brogy's shield.

The immense force sent Brogy stumbling backward several more steps.

From Dorry's perspective, the sight of the two vastly different figures—one towering and massive, the other small yet ferocious—engaging in a relentless exchange of blows was nothing short of astonishing.

Each strike landed solidly, their attacks clashing in pure displays of strength.

Dorry's eyes glimmered with a deep sense of awe.

This young outsider… could hold his own against Brogy in a contest of raw power? How incredible!

What incredible physical prowess!

Who exactly was this outsider?

Did he possess the bloodline of the Giants?

Ron and Brogy clashed with full force for over ten minutes.

Ron's clothes were in tatters, and his body bore several wounds and minor fractures. Despite this, his fighting spirit remained undiminished. Brogy, on the other hand, was panting heavily, his hands gripping his axe and shield feeling numb and stiff. His eyes, which initially held shock, now carried both the battle spirit of a warrior and a newfound respect for Ron's strength.

Throughout their duel, Brogy had clearly felt Ron's overwhelming power.

"Let's call it a day, Brogy," Ron said with a smile as he stood on the ground, looking up at the towering giant. "Next time, I'll treat you to some drinks."

Brogy grinned broadly. "Wahaha! That sounds perfect to me."

"Brogy."

A loud voice echoed nearby.

Brogy turned his head and saw Dorry standing not far away. His expression hardened as he asked, "Dorry, what are you doing here?"

"With such a commotion, how could I not come and see what's going on?"

"It's none of your business."

"I wasn't planning to bother you," Dorry replied casually. Ignoring Brogy's irritation, his gaze shifted to Ron, who stood amidst the fractured ground below. "That was quite the impressive duel, outsider," Dorry said. "I am Dorry, a warrior of Elbaf and the Blue Ogre. May I know your name?"

Ron raised his head and smiled back. "Ron. I'm a traveler from beyond this island."

"Ron, is it? I'll remember that name," Dorry said with a nod. His eyes gleamed with a spark of battle spirit as he continued, "Ron, do you have time tomorrow? Would you spar with me as well?"

"Of course," Ron replied without hesitation, nodding firmly.

"Dorry, you…" Brogy growled, glaring at him with clenched teeth.

"It's only fair for each of us to have a turn," Dorry said with a shrug. "You've already had your fight, haven't you? That should be enough to satisfy you."

Dorry then shifted his gaze back to Ron and added, "I've prepared some delicious roast dinosaur. Would you like to join me for a meal?"

"No, that won't be necessary," Ron replied with a shake of his head. "My companions have already cooked some food."

"I see… In that case, I'll head back for now. I'll be waiting for you tomorrow morning over there."

With that, Dorry turned and left, leaving Brogy grumbling to himself.

Ron made his way back to the wooden house.

When Conis and Robin saw him, his clothes in tatters and his body covered in injuries, their faces turned pale with shock.

"What happened to you?" Conis exclaimed, staring at him in disbelief. "Did you run into some powerful monster on this island?"

Ron scratched his head and gave them a quick rundown of what had transpired.

"Wait, what?" Conis stared at him blankly. "You mean you were the one fighting Brogy just now… Captain, was that really you?"

Ron nodded with a smile.

Robin, on the other hand, sighed in exasperation. "You really are reckless, aren't you? Picking a fight with a Giant warrior… No wonder you're in such a state. Stay here; I'll go get some medicine."

Before Robin could head upstairs, Ron stopped her with a gentle tug on her arm. "Don't bother," he said, smiling. "These are just minor injuries. I'll be fine by tomorrow morning."
