One Piece: With Sign-in System

Under Sai's astonished gaze, Chinjao's massive fist was forced back by Ron's punch. His enormous body staggered from the impact, retreating two full steps.

"How is this possible… The leader was actually pushed back?"

"The leader must have been careless!"

"Yeah, that has to be it!"

"But that guy… he seems really strong."

The members of the Happo Marines whispered among themselves, their disbelief mixing with growing unease.

Chinjao, feeling the terrifying power contained in that punch, steadied himself and fixed his sharp gaze on Ron who had landed gracefully on the emerald-green icy surface.

"The strength of that punch… It feels so much like that accursed Garp…" Chinjao muttered, his eyes narrowing. "Boy, state your name!"

Ron raised his right hand and lightly clenched his fist. Instantly, his Armament Haki hardened, transforming his entire arm into a deep obsidian hue.

With a smirk tugging at the corner of his mouth, he replied to Chinjao, "Beat me, and I'll tell you."

"Interesting!"

Excitement flickered across Chinjao's face.

He raised his massive, muscular right arm, which immediately hardened with Armament Haki, and swung it down toward Ron with crushing force.

Ron met the attack head-on. His right arm, also encased in hardened Armament Haki, pierced through the air, carrying a fiery wave of pressure as it shot upward to collide with Chinjao's.

When the two darkened fists—one massive, one relatively small—clashed, the world seemed to hold its breath.

Boom!

The frozen atmosphere between them shattered like glass struck by a hammer, splintering into countless silver-white cracks.

As their fists collided, the clash awakened Chinjao's Conqueror's Haki. The moment Ron sensed it, his own Conqueror's Haki—at Level 2—surged forth like an enraged tiger that had been provoked.

The two opposing waves of Conqueror's Haki collided fiercely.

Buzz!

A tangible pressure rippled outward from the collision, spreading in waves. Behind Sai, the members of the Happo Marines, unable to withstand the overwhelming force, dropped unconscious one after another, their eyes rolling back as they collapsed in heaps.

Even Sai himself wavered momentarily, snapping out of it only to feel cold sweat dripping down his forehead.

"This… This is the collision of Conqueror's Haki?! At this level…?"

As their Conqueror's Haki clashed, crimson lightning bolts streaked through the air around them. Visible shockwaves rippled outward from the point where their fists collided, twisting and curling as they spread across the icy landscape.

Wave after wave of oppressive power burst forth, accompanied by roaring winds. The unconscious members of the Happo Marines were sent tumbling across the ice like leaves caught in a storm.

Even the sky above seemed to respond, darkened with ominous red cracks that spread across the heavens. The frozen island beneath their feet trembled violently under the force of their Haki, and the surrounding ocean churned into raging waves.

Robin and Conis couldn't hide their astonishment. This was their first time witnessing the clash of Conqueror's Haki, and its sheer intensity left them deeply shaken.

Bonnie, now in the form of a pink-haired young girl, stared at Ron standing before them. His black coat billowed fiercely in the stormy winds, his back to her and the others.

Compared to Chinjao's massive, imposing figure, his silhouette seemed almost insignificant.

Yet, at this moment, he carried the weight of an unstoppable force.

In Bonnie's eyes, however, that figure seemed infinitely tall. It was as though as long as this figure stood before her, she felt an overwhelming sense of security.

The reason she had insisted on boarding the ship in the first place was partly because of Ron's incredible strength. But more importantly, she had witnessed with her own eyes his willingness to risk his life fighting a Marine Admiral for the sake of his crewmates.

It was precisely this unwavering loyalty that had made Bonnie resolute in her decision to join the crew no matter what. And over the past year and a half, she had come to deeply realize how correct her choice had been.

Thinking of this, Bonnie gazed at Ron's back with a smile tugging at the corner of her lips.

Compared to his battle with Aokiji a year and a half ago, her captain had grown far stronger.

A mere pirate with a bounty of 500 million in his prime? How could someone like that possibly stand against him?

At that moment—

The terrifying power contained within Ron's blackened fist erupted with explosive force. In an instant, it completely overwhelmed Chinjao's punch. In the eyes of Sai, who was practically bulging them out of his head in disbelief, the massive figure of Chinjao was sent flying backward with a single punch!

"He… He actually sent the leader flying with one punch…"

Sai, gripping his Sword tightly, trembled as he stared at the calm, composed boy. Cold sweat poured down his face. "Where in the world did a monster like him come from?"

Chinjao's massive body crashed heavily onto the unyielding surface of the ice bed. When he opened his eyes again, looking at Ron, who hadn't moved a single step, there was now a trace of shock in his gaze.

"What terrifying strength… Could this guy have the unique bloodline of the Giants?"

Despite recognizing the immense power of the mysterious boy before him, Chinjao had no intention of conceding defeat.

He stomped down forcefully, propelling himself like a cannonball. His figure shot forward, closing the distance in an instant. The flattened top of his head, hardened with Armament Haki, aimed straight for Ron, and before it even reached him, an overwhelming shockwave rushed toward Ron.

"Hasshoken: Weaponized Head Strike!"

As the attack approached, Ron wasn't thinking about dodging, blocking, or countering. Instead, a peculiar thought crossed his mind.

Would his punch this time be enough to restore Chinjao's flattened head back to a sharp, pointed one?

Probably, right?

He just needed to adjust the angle.

While entertaining this thought, Chinjao's head—blackened and hardened by Armament Haki—arrived right in front of him.

Ron raised his obsidian-black right arm, swinging it with twice the speed of his previous punch. His fist collided squarely with Chinjao's armored head.

Bang!

With a resounding boom, a violent gale swept across the surroundings.

Ron unleashed the full power of his 3,000 Vitality points, and the result was immediate. Chinjao's flattened head began to deform, as if molten steel was being reshaped. From its previously flattened state, it started to return to a sharp, pointed cone.

"Wha… What?!!!"

Sai's eyes nearly popped out of his head as he witnessed the scene unfold before him.

Conis, Robin, and Bonnie were equally dumbfounded.

"A flat head… can actually be punched back into a pointed one?"

Ron's punch, even more devastating than the last, not only reshaped Chinjao's head into its original conical form but also knocked him unconscious. The immense force hurled Chinjao's body backward, sending him crashing heavily into an icy peak in the distance.

The newly restored conical head pierced through the hard ice peak, embedding the unconscious Chinjao diagonally into the icy mountain, creating an incredibly unique and bizarre sight.

Half a day later…

On this emerald, crystalline ice continent, Chinjao—now with his restored conical head—knelt with Sai and the entire Happo Marines before Ron and his crew.

"This kindness... even a thousand deaths would not be enough to repay it! From this day forward, Lord Ron will forever be the greatest benefactor of the Chinjao family and the Happo Marines! If you ever have a command, I, Chinjao, will obey it unto death without hesitation!"

Kneeling on the icy ground, Chinjao bowed his head low, his voice filled with gratitude.

Robin, Conis, and Bonnie, watching this legendary pirate with a bounty of 500 million berries in his prime, humbly offer his loyalty, accompanied by the sea of his subordinates bowing in unison, couldn't help but feel deeply shaken.

"Unto death without hesitation?"

Hearing this, Ron chuckled. He lightly tapped his foot on the icy surface beneath him, its clarity resembling a frozen lake. "What if I said I wanted all the treasure buried beneath this ice?"

Chinjao froze for a moment, a flicker of conflict and hesitation flashing through his eyes. However, his expression quickly turned resolute.

He raised his head to meet Ron's gaze and said earnestly, "If Lord Ron desires it, I will break open this jade-like ice bed and present the treasure within to you."

Compared to the life-changing kindness of restoring his conical head, this treasure was insignificant!

With this thought, Chinjao immediately activated his Armament Haki, hardening his restored conical head. Channeling an immense amount of power to the sharp point, he slammed his blackened head into the seemingly indestructible icy ground with a resounding crash.

Boom!

The ground trembled violently.

From the impact point of Chinjao's head, a series of fractures spread outward like a spider's web, until the icy surface split open with an earth-shattering crack.

A massive fissure, stretching hundreds of meters long and dozens of meters deep, appeared in the thick ice sheet.

What lay exposed beneath the cracked ice bed was a dazzling hoard of treasures radiating a mesmerizing glow.

"Whoa!!!"

Bonnie, still in her small child-like form, instantly had her eyes turn into symbols of beli, shining brightly.

Even Conis and Robin were taken aback, their faces showing undisguised astonishment.

"There's actually so much treasure buried here…"

"Just how much money is this?"

As far as the eye could see, within a radius of a hundred meters, the ground was covered with an endless layer of gold, silver, and precious gems.

Standing atop the glittering treasure, Ron looked at Chinjao and said calmly, "There's no need for me to take all of it, but I will take a portion before I leave this island."

Hearing this, Sai and the other members of the Happo Marines had tears welling up in their eyes. They looked at Ron with immense respect and gratitude.Some of them even began to cry openly, overcome with emotion.

"Lord Ron… truly a noble and selfless man…"

Chinjao, however, appeared flustered. "How can that be? Even if I gave you all the treasure here, it wouldn't be enough to repay your kindness. How can you only take a portion…?"

Ron merely smiled and said, "Well then, I have one more favor to ask of you."

He pointed toward Enzo, happily playing with a pile of gold coins. "That's my apprentice, a Kung-Fu Dugong from Arabasta. His name is Enzo. For the next few months, I'd like you to teach him some martial arts."

Chinjao blinked in surprise and turned to look at the tiny Dugong wearing a sturdy steel vest.

Hearing their conversation, Enzo looked over with sparkling eyes, his little tail wagging furiously as he stared at Chinjao with excitement.

"Eh? Master! Is this powerful old man really going to teach me martial arts?"

Hearing Enzo's words, Chinjao, Sai, and the rest of the Happo Marines froze.

A Dugong… was talking?

Ron looked at Enzo and chuckled. "Show them your full strength with a punch."

"Understood!"

Enzo's expression turned serious as he prepared to strike.

What happened next nearly made Chinjao, Sai, and the entire Happo Marines's eyes pop out of their sockets.

The Dugong pulled back its right fist, and a surge of Armament Haki erupted, instantly coating its tiny fist in an iron-like black sheen.

With a focused expression, Enzo threw a punch.

Boom!

The air in front of him exploded with a deafening roar. Accompanied by an overwhelming shockwave, the punch blasted forward, sending piles of gold coins flying dozens of meters away.

"...Eh??!!!"

The Happo Marines members behind Sai stood frozen, their eyes wide and jaws nearly hitting the ground.

Ron turned to the dumbfounded Chinjao and Sai, grinning. "What do you think?"

Recovering from his shock, Chinjao quickly straightened up and assured him, "There is no issue at all! I will teach him everything I know!"

With that promise, Ron took 40% of the treasure from the icy continent before departing with Robin, Conis, and Bonnie.

Enzo, however, stayed behind with Chinjao to learn the Iron Head Technique and the Eight Impact Fist.

Time flew by, and in just a few months, Ron and his crew completed their exploration of the remaining islands in the West Blue. When they returned to the Land of flowers, they found Enzo, now well-versed in the Eight Impact Fist, the Iron Head Technique, and other martial arts, ready to rejoin them.

...

At the end of 1516 in the Sea Calendar, The Traveler left the West Blue.

At the beginning of 1517, they arrived in the North Blue.
