I Promised to Win with Roger… But I Was Just a Kid

Pushing open the wooden door of the forge, the heat wave hits you. An old blacksmith with white hair is hammering a piece of red-hot metal, sparks flying everywhere.

"Customer, please feel free to look around. I no longer make custom products. If you like it, buy it. If not, it doesn't matter." The old blacksmith didn't even raise his head.

Rhett's eyes were immediately drawn to a huge sword hanging on the wall. It was a two-handed sword that was pitch black and had a blade width of about nine inches.

"This, this sword…" Rhett's eyes widened and he walked over involuntarily.

The old blacksmith finally raised his head and stared at Rhett "Kid, that sword is not a toy. Go. Go. Go and play outside."

Rhett was unconvinced "I'm not kidding! I'm serious! And I really want a heavy sword as a weapon"

Roger came over and whistled "Oh? This sword is interesting."

The old blacksmith snorted, "This is my masterpiece, named 'Kuroshio'. The materials were obtained by chance when I was young, and most people can't even lift it."

Rhett swallowed at the weight, but couldn't give in "Let me try!"

The old blacksmith sneered "Okay, if you can lift it, I'll give it to you."

Rhett took a deep breath and put both hands around the hilt of his sword—

"Ugh… it's so heavy!"

The sword remained motionless.

Gaban laughed, "Forget it, kid. You can't even lift a sword with your tiny body."

Rayleigh frowned. "The weight of this sword is certainly not suitable for a child."

Roger stroked his chin, thinking "Rhett, try using Armament Haki."

The old blacksmith's eyes lit up when he saw this five or six-year-old child actually using the Armament Haki.

Rhett was stunned for a moment, then nodded. He closed his eyes, mobilized all his strength, and slowly wrapped his Haki around his arms.

"Dri—!"

"Kuroshio" was finally lifted, but Rhett's arms were already shaking.

The old blacksmith narrowed his eyes "...Interesting little devil."

Roger grinned, "How's it going, old man? The sword belongs to him?"

The old blacksmith was silent for a moment, and finally sighed "... That's all. This sword will just gather dust if it stays here. Since you can pick it up, take it away."

Rhett's eyes widened in surprise: "Really?!"

The old blacksmith turned and walked towards the furnace, waving his hand with his back to them "Remember, the sword is a weapon, but also a companion. Don't let it down. The name is Kuroshio. Can you make him famous in the sea?"

Rhett understood why Captain Roger made such a solemn promise to Uncle Tom.

It was a promise from one man to another man.

Rhett held Kuroshio in front of him and looked at the old blacksmith with determined eyes "I will make this sword famous all over the sea. This is my promise."

"Hahahahahaha, I believe you. Let's go. I'm going to retire. This is my proudest work and also my last work. I will always keep an eye on you."

Rhett, who got Kuroshio, tied Kuroshio to his body. He had to adapt to Kuroshio's weight as soon as possible. He carried Kuroshio on his back and ran ten laps around the Water Seven Capital. The journey that was originally easy turned out to be unusually long.

Even though Rhett has monster-like physical strength, he is sweating profusely. Rhett is nearly six years old now. Even though the muscle density in the One Piece world is relatively high, Rhett is only about 60 pounds.

This big sword is really not light for Rhett, which is because Rhett is a time traveler and has a cheat.

If it were anyone else, Kuroshio would be so powerful that it would be hard to even live a normal life with it, let alone fight with it.

But Rhett was not discouraged. He believed that when he could use Kuroshio with ease, his lethality would be even greater.

Didn't you see that Lola turned Luffy into Nightmare Luffy? That weapon required eight battle-hardened pirates to lift it together, and it wasn't much heavier than this.

Rhett's feet sank deeply into the dock soil of the Seven Waters City. This huge sword, taller than him, was now pressing down on him like a small mountain.

You have to know that all of his predecessors who traveled through time had monstrous physiques. It was easy for them to be three or four meters tall when they were four or five years old. How come he was still a little kid?

"Nin-..." Rhett gasped, his vision blacking out. Even with the blocking of the armed Haki, the rope that helped Kuroshio cut into the flesh of his shoulders.

You should know that the strength of the Armament Haki is not high, Rhett can now keep it open,

Gaban leaned on the railing on the shore and ate an apple "Little boy, do you want me to help you hold it for a while? Take a break, anyway, this sword is yours and you can't run away."

"No...no need!" Rhett squeezed out two words from between his teeth and took another step with his lead-like legs "This is an agreement between two men."

Rayleigh watched from a high vantage point, his eyes thoughtful behind his lenses.

He found that although Rhett's steps were heavy, the spacing between each step was exactly the same - this kid was using his Observation Haki to accurately control every bit of muscle strength and manipulate it delicately. He shook his head and laughed,

"Why you want to use the big sword when you have such delicate manipulation and observation skills?"

In fact, playing with the broadsword Rhett is a carefully considered decision. If you play with a rapier or a sword, Rhett can certainly control them finely. The disadvantage of the heavy sword is that it consumes physical strength and moves slowly, and requires extremely high physical fitness from the user.

He never worried about his physical strength.

His slow movements could be compensated by the Mist Mist Fruit. Under the same strength, Rhett believed that if he was not a swordsman specializing in physical fitness, no one could withstand his sword.

Maybe we should ask if swordsmanship should not be unstoppable? ? ?

'I am the user of the Mist Fruit. If you let me fight him head-on, I would be considered to have high character if I don't hit him with my black sword. I have abandoned my personal qualities and want to live a low-key and insidious life.'

"Bang!"

At the end of the tenth lap, Rhett finally couldn't hold on and fell to the ground with his sword. Kuroshio hit the ground with a dull roar, scaring the nearby seagulls away.

Roger laughed and picked up Rhett "Haha! You can carry him all the way on your back on the first day, not bad!"

"No... No..." Rhett collapsed in the captain's arms, unable to even lift a finger, "The last half circle... I crawled..."

The old blacksmith stood at the port, the pipe in his hand flickering. He watched the little guy struggle to get up and once again shoulder the giant sword, a smile flashing in his eyes.

"Hey, kid." The old blacksmith suddenly called out, "Do you know why it's called 'Kuroshio'?"

Rhett raised his sweaty little face. He didn't expect the old blacksmith to appear here.

"The tide may seem slow, but it can smooth out the hardest rocks." The old blacksmith blew out a smoke ring. "A heavy sword has no edge, and great skill is not skillful."

"How can I hand it over to a little brat like you with just a few words? Of course I have to come and see it with my own eyes. Come on, kid. I'm rooting for you."

"Just wait, old man, until I become famous all over the world."

In the following days, in the yard where Rhett lived

In the early morning mist, Rhett practices the most basic chopping moves.

Under the scorching sun at noon, he tied Kuroshio upside down on the mast and did crunches

In the moonlight at night, Rhett use his Haki to nourish Kuroshio.

Rhett has never been so desperate. It turns out that the agreement between the two men is the best stimulant.
