[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]

[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!

In the era of Rocks, on the sky island of Biruka above the sea of ​​clouds, a boy named Rock, who was taken in as an infant and has memories of his past life, awakens superhuman perception during his ten years of growth. His Observation Haki is as sharp as the wind and as vast as thunder.

Their peaceful life was quietly changed by a strange "thunder" coming from the depths of the sea of ​​clouds.

In search of answers and to take control of his own future, Rock leaves his familiar village and heads toward the unknown source of thunder.

This journey will slowly unfold from the sea of ​​clouds of the old era.

This is a slow-burning, lengthy story, but one destined to ignite the entire world—

In the year 1494 of the Sea Calendar, Orochi, along with Higurashi and Higurashi, secretly murdered Sukiyaki, plotting to seize the Shogun's position. They even allied with Kaido of the Beasts, plunging the entire Wano Country into panic. "Wano Country? I don't care for it, and it's not your place to lay a finger on it. Kaido, Orochi, offer me your heads!" A man named Kozuki Seimei led the Shadow Squad back from the depths of hell, reclaiming control of Wano Country. He slew Orochi, crushed the Beasts Pirates, and pursued Kaido all the way to the West Blue… leading his nine Shadow Shoguns and eight Demons, he rose from Wano Country to rule the entire world.

Thirty-eight years ago, the God Valley Incident was brought to a close by the World Government, marking the end of the Rocks Pirates. However, the Celestial Dragons, high and mighty, were unaware that an even more terrifying monster was about to unleash his power. Soon, his enemies realized that beheading, piercing his body, even reducing him to ashes, could not truly kill him. Only when blood flooded the empty throne did they understand who their opponent truly was. A man who had developed the Bat-Bat Fruit—Mythical Zoan type, Vampire form—to an unprecedented level, a man who had mastered all three types of Haki. His name was Nereus, Lord of the Deep Sea, Undying King, Liberator… His name has never ceased to resound on the seas… (Completed works: "Arceus's Pirate Journey" (12,000 average reads), "My Piltover Technology is Far Ahead" (8,000 average reads).

PS: Not invincible at the beginning, early training is slow

There are no self-created devil fruits. All mythical beasts are from the original works, games or official activities. There is no magic modification.

At the start, players can choose between one trillion resources or 100,000 combat power.

Five points of combat strength is equivalent to an average adult holding a gun.

A combat power of ten points already makes one a powerful martial artist, capable of easily taking on ten opponents.

With a combat power of 100, its full-power qi cannon is stronger than a missile, and it's not impossible for it to destroy a mountain.

With a combat power of 10,000, one can easily annihilate a city with a wave of their hand, and level the ground in a little while.

In the world of One Piece, a combat power of 100,000 is practically invincible. The only things to fear are those Devil Fruits with rule-based abilities and the unknown Uranus Im.

Is there even a need to choose?

"System, select 100,000 combat power!"

The blonde, blood-red-eyed beauty stood with her hands on her hips, proudly displaying her ample bosom, and spoke thus.

Rocks faked his death in the Valley of the Gods and spent decades regaining his will. He returned to the sea and gathered his crew to conquer Mary Geoise.

Bucky the Joker separated his consciousness and Haki, and just as Shanks was dying, the power he had split off returned, intending to drag the entire world into the Dark Ages.

The navy was struggling to cope with the rapidly expanding pirate forces and had to expand its military on a large scale to prepare for war, increasing the number of admirals to 12.

Straw Hat Luffy successfully received the inheritance of Shendu and ate the Balance Devil Fruit (Tiger Talisman), which can balance the demonic power within him.

This book is extremely messy and completely haphazard; it's basically just writing whatever I dream about.
