One Piece: Start as a mythical beast, practice to become stronger

The sea breeze howled, stirring up surging waves, as if cheering for the battle about to erupt.

Jin An gripped the hilt of his blade tightly, sensing the aura of the colossal beast before him.

His mind and body seemed to merge with the blade in his hand, and with each surge of power, the blade's edge seemed to tremble.

Jin An drew his sword from its sheath in a flash.

"Clang!"

On this vast sea, the crisp sound of the blade was clear and loud, like a long, drawn-out zither melody, conveying the determination to kill far into the distance.

Jin An waved his hand, and the blade flashed through the air like lightning, emitting a sharp whistling sound, as if tearing through the fragile film of time and space.

His movements were swift and fierce, each swing seeming to cleave the entire sea in two, the astonishing sound of the blade like a heaven-collapsing roar, shaking the entire sea and seemingly stopping the waves from breathing.

The sound of the blade had never been so clear, especially considering this was the boundless sea. Kuzan and the other marines simply couldn't believe their ears.

The Sea King seemed to sense the protagonist's power, pausing for a moment with a flash of surprise in its eyes.

But this momentary pause was only fleeting, and then its eyes surged with an even stronger intent to destroy. It raised its massive body, as if to crush the entire sky.

Jin An was not afraid, his eyes flashing with a burning light, even licking his lips. The Sea King before him was already his prey. So far, he had not tasted what a Sea King tasted like.

"Roar!!!"

The Sea King in front of him was huge and mighty, its body like a moving mountain, covered in thick scales that shimmered with a metallic luster.

Its eyes shone brightly, filled with a fierce aura, as if to devour the protagonist alive.

Jin An soared into the air, wielding his sharp blade. The light of the blade flashed, like lightning cutting through the night sky, illuminating the rolling sea.

The dazzling white light illuminated the entire world, and at that moment, even the light of the sun was obscured. Seeing the sword mark that pierced through the heavens and the earth, Doflamingo felt his jaw about to drop.

"Wow!!!"

On the warship, the marines gathered on the deck shouted in amazement, because before their eyes, a huge sword mark, like a miracle, was reflected in their pupils.

And where the sword mark had passed, the giant Sea King that had filled them with despair was split in two...

Before the giant Sea King could even feel the pain, its body swayed and eventually crashed heavily onto the sea, stirring up a huge wave.

Blood instantly stained the sea red...

The marines looked at Jin An's figure on the sea.

That figure stood towering on the sea like a deity, his coat fluttering in the wind behind him.

They witnessed this fleeting battle, saw Jin An's casual killing of the giant Sea King, and their awe of Jin An was like a surging river, impossible to contain.

At the moment the giant Sea King fell, the marines seemed to release the enormous pressure that had been pent up in their hearts. They stared at Jin An in stunned silence, their eyes filled with shock and awe.

"This is simply incredible! As expected of Captain Jin An! His swordsmanship, his spirit, it's beyond my imagination!"

"I've never seen anyone able to face such a behemoth with such ease. He... he is my idol!"

Jin An floated on the sea, but at this moment, he was worried. He now had the feeling of having a mountain of treasure but not knowing how to use it.

"This guy is too big, the warship can't fit it at all, what should I do..."

"......"

"Captain Jin An is checking his spoils of war. I didn't expect him to be so handsome even at this time!" The female marine on the warship said admiringly.

Kuzan looked at the marines beside him and smiled self-deprecatingly. He had been worried about Jin An's image in the hearts of the marines, but he didn't expect things to be so unpredictable...

......

Behind him, the huge Sea King's corpse became as small as gravel. Jin An could only take away the most delicious part of the meat.

As for the rest, Jin An could only reluctantly abandon it with tears in his eyes...

He moved from the bow of the ship to the stern, and only when the Sea King's figure disappeared did he reluctantly withdraw his gaze.

Doflamingo couldn't understand Jin An's state of mind. He had clearly accomplished something so awesome, but he was so reluctant to part with the Sea King's meat.

"I want to be like you!" Doflamingo's eyes flashed with light, a worship of the strong and a desire for strength.

"What?" Jin An couldn't understand Doflamingo's words.

"I mean I want to become a strong person like you! I felt what a real strong person is like for the first time. I want to have the power to subvert everything!" Doflamingo imagined the future.

He wanted to pull those Celestial Dragons who called themselves 'descendants of gods' from their thrones... and trample them underfoot!

And now, the road to becoming stronger had been paved under his feet. As long as he followed Jin An, he believed that the future in his heart would definitely be realized.

Jin An looked at the kid in front of him who started giggling after speaking and was a little confused, and silently distanced himself.

"How many things are you hiding from me?" Kuzan's voice sounded faintly in Jin An's ear.

He thought he knew Jin An well enough (after all, he was a little fan), and he knew that Jin An could defeat the Sea King, but he didn't expect to kill it with one move.

"Damn it!" Jin An was startled. "Can you not speak in this tone, I'm scared..."

Why did this tone sound so much like a girl abandoned by a scumbag? How could a grown man speak so resentfully?

Jin An crossed his arms, feeling goosebumps all over his body.

He pondered for a moment and replied, "My strength is... okay."

"Someone like you... I should be able to beat ten of you."

Uh......

There were many marines around, and they were also curious about Jin An's strength. However, they didn't expect to hear such an explosive description.

When did Kuzan become a unit of measurement? They had never dared to think about such a thing before.

"I really can't understand you more and more. I don't know what your strength will be like the next time I see you take action."

Unconsciously, darkness enveloped the sea.

The sea was shrouded in darkness, its vastness seeming to contain endless mystery and danger.

Moonlight penetrated the gaps in the clouds, casting a faint silvery-white light, like a bright moon in the sky sprinkling on the surging sea.

However, this faint light only barely illuminated a small area of the sea, and the rest remained deep in darkness.

On this dark sea, the waves surged, emitting a low roar, as if a group of bound beasts were calling for some unknown power.

Or the unknown creatures hidden in the deep sea, they loomed in the darkness, giving people a mysterious and uneasy feeling.

Without the bright sunlight and clear blue sky of the day, it was replaced by a deep and treacherous atmosphere.

People sailing on this sea at night seemed to be in a world full of unknowns and dangers, and every shadow might hide a deadly threat.

"Little ones, there's a warship ahead. It's your time to shine!"
