You've been transported to the world of One Piece, acquired the Rumble-Rumble Fruit, conquered Skypiea, and unleashed your ambition upon this world. Live a wild and unrestrained life, seizing power and beauty for yourself.

[Adventures in the Roger Era] + [Gunslinger] + [Pure Devil Fruit Development] + [No System] + [Unchanged Power Levels]

Darrow travels to the world of One Piece and becomes the younger brother of Roger's wife Rouge. Fortunately, Roger has not yet conquered the Grand Line, so Darrow still has time to change his sister's tragic future.

With the power of the Compression Fruit and his innate Observation Haki, Dead Eye, Darrow grew step by step and made a name for himself on the high seas, writing his own legend in an era where heroes like Roger, Rocks, and Whitebeard rose to prominence.

The story begins with the crew's adventures (partially original storyline + extensive references to the old era in the manga), and after Roger's death, they become one of the Four Emperors and vie for supremacy.

[The strongest gunslinger] + [The most imaginative fruit development]

Pirates are evil? The Navy is righteous?!

Haha, who knows? This idea has been changed countless times!

Only those at the top can define justice, and will justice prevail?

That's for sure, because only the victor is righteous!

...

Does the winner always prevail?! If I had a chance, I would want to change all of this.

As soon as the words were spoken, two moons appeared in the sky, and a golden lightning bolt struck straight down.

Xia Wu: No way, you're serious? (°ー°〃) I was just bragging.

A casual, boastful remark landed Xia Wu in the world of One Piece. Fortunately, the perks of being a transmigrator allowed him to survive in the dangerous pirate world.

Until one day, a blond man appeared, and the wheel of fate began to turn wildly.

"Boy, be my son, bear my name, and make a name for yourself on this vast ocean!"

"Huh? Are you sure?! Let me taste a liter of your blood first to see its power."

Whitebeard: "(ー_ー)!!"

[Legendary Whitebeard Newgate bloodline factor detected - refining earthquake power, the Creator of All Things System officially activated...]

Has it finally arrived?

[Earthquake Power + Overpowering Heavy Armor => Super Long Standby Earthquake Set]

[Burning Flame + Thunder Stone => Thunderfire Dragon Set]

...

[Detected that the Supreme Grade Sword Ace contains bloodline factors of Rocks, Shiki, Roger... , extract?]

Yes, yes, yes!

Hehehe, world, here I come! Are you ready?!

Is justice only served by the victor?

I am justice!

Celestial Dragon: Yes, yes, you're right!

Im: 6!

[Three types of Haki + decisive killing + no trolls + physical skills + kingdom rise + no Devil Fruits + slow start + farming + more exciting content to come]

The first few chapters might be a bit disjointed and the pace a little slow, but please keep reading, it gets even more exciting later on!

Ivan has been granted a "Transmigrator Experience Card"—becoming the prince of Alabasta! He thought that by binding with the system, he could take off on the spot and beat up the Four Emperors and generals?

The system immediately responded with: "Sorry, young man, you've kidnapped the wrong person!"

He ran away at lightning speed, leaving behind only a small "breakup fee"... Well, the magic touch doesn't work, I'll have to face it all myself!

Fortunately, Ivan deeply understood the number one law of the pirate world: might makes right! All three types of Haki? Train! Top-tier physical skills? Grind! Devil Fruits? Ha, a real man lets his fists do the talking.

As a result, the style of Alabasta began to change drastically:

A chance encounter with an older man who smiled? Ivan's persuasive words are a cure for all kinds of confusion! He smiled and said, "This young man... is destined to be a wise ruler!"

Water Seven recruiting Iceberg? Just empty promises? No, we're drawing up a grand blueprint for the future! Iceberg: "Your Highness... is worthy of my following!"

Brook was recruited from the Devil's Triangle, moving Moria? Music is needed, bones must be collected, and shadows? Here you go! Brook/Moria: "Ivan... is a good partner!"

A Skypiea player brutally beats up a teenage version of Enel, the God of Thunder? Enel (with a swollen face): "...Gan...Ganlin-niang..."

Starting from a desert kingdom, Ivan's goal was simple: to plant the Alabasta flag all over the Grand Line! Decisive and ruthless, he doesn't fawn over others; he subdues people with force—that's his style! This old era needs a new pillar!

(The main character is a pirate, a great swordsman, a single female lead, not a harem, and the events before this are unrelated to the main character's group.)

He survived countless extreme battles, slaying all enemies who stood in his way.

His sword-drawing technique was as fast as lightning, shaking the world.

He is the brother Nico Robin tearfully recognized, the nightmare of the Celestial Dragons, the great enemy of the Navy, and a walking, single Yonko.

He is a man who walked out of hell alone from the very beginning of the Great Pirate Era.

Long, flowing hair, black robes, and a free-spirited demeanor.

Everything they do is aimed at overthrowing the tyranny and distorted rule of the world government.

Arthas: "Don't listen to their nonsense. I am a righteous person. Although I have slaughtered many lives, it was all for the benefit of the sea and for the benefit of you."

Ye Cheng, a barber, traveled to the world of One Piece and obtained the superhuman Fa-Fa-No-fruit.

I wanted to stay in this world, so I tried every possible way to join the navy and became a navy. But when I was helping Tina trim her hair, the system awakened...

So, five years later, he faked his own death and escaped from the Navy. From then on, the Navy lost a teacher named Tony...

Sanji: Why does it take only 30 seconds to trim my hair, but it takes half a day for Nami and the others?

"Cutting your hair adds two points of stamina, and cutting their hair adds dozens of points. Do you think I'm stupid?"

Luffy: Where did Zang Ai Ye Cheng go again?

Zoro: Let’s go to the Kingdom of Women and look for it…
