When the socially awkward former Water Pillar Tomioka Giyu suddenly travels to the world of One Piece and is forced to bind to a baffling "Interpersonal Communication Manual" system, witnessing the Straw Hat Kid on the execution platform, about to be executed by Buggy, saving him, breaking the platform, and becoming entangled seem like the natural progression. Luffy: "Wow! What a cool move! Be my partner!" When the taciturn Giyu encounters the most free-spirited pirate group, this sea is destined to be turbulent by the least chatty swordsman. ... "Let's have a party, Giyu!" [Interpersonal Communication Manual] [Target: Monkey D. Luffy] [Status: Extremely Excited] [Preferences: Throwing parties, hanging on to the host] [Suggestion: ... (Analysis impossible)] Right now, that rubber boat captain is swinging from my only arm. What should I do now...

[One Piece fanfiction + mythical beast species + crew companion + no system + making up for regrets]

[PS: Momonosuke must die.]

Lu Yu, who is hailed as a successor of ancient Chinese medicine, is transported to the world of One Piece after criticizing the plot of One Piece once again.

There is no system, and no old man.

Lu Yu could only accept the arrangement of fate and begin to make up for the regrets in his heart.

Hmm... and change the world while we're at it.

From that moment on, the world of One Piece changed:

The revolutionary army was established ahead of schedule and developed rapidly; Sabo danced with a steel pipe and reminisced about the past.

Kuina roams the world with her sword, hoping to rekindle an unfinished duel with someone.

Bellemere smiled as she planted orange trees, hoping her daughter would return and taste the sweetest oranges;

Banjina and Kaya stared blankly at the sea, thinking of the most important person in their hearts;

Zeff stood on his feet, tossing the wok, and occasionally smacked people with his tall chef's hat;

Hiluluk is still a quack doctor, arguing with some 140-year-old witch;

On a certain golden spaceship, thunderstorms raged and screams echoed...

Lin Feng felt that it was too difficult for him to travel through time and become an invisible and intangible "online god" in the pirate world.

Fortunately, his followers, though poor, were devout enough.

[Ding! You have received the following pending wishes! ]

[A prayer from old Joseph: Please save us from the suffering of the "blood tax"!]

[Prayer from the widow Martha: Please bless my child to grow up safely! ]

[Nami's prayer (faint): Who can... help me redeem the village...]

Luffy's strong wish: I'm so hungry! God, please give me some meat!

Lin Feng smiled slightly, even gods have to pay attention to KPI.

So, when Nami desperately sacrificed the stolen blood-stained treasure, the next second, the [Holy Light Gold] returned a hundredfold filled the deck of the Golden Merry.

Nami: "Wow... there really is a god..."

Sanji: "This... this is a dream ingredient for bathing in divine grace!"

Zoro: "This protective power... is quite interesting."

Luffy: "Wow! That's awesome! It's decided, our next partner will be a god!"

However, as Lin Feng's name became famous throughout the East China Sea, troubles also followed.

The CP agents of the World Government, the elite fleet of the Navy Headquarters, and the Blue Star compatriots who are eyeing them covetously...

They didn't know that this seemingly benevolent "Guardian of the Tide" had countless heroic spirits ready to go in the [Sea Soul Hall] under his seat.

【Multiple female protagonists】【Multiple fruits】【Space】【Both good and evil】

【Murder of Momonosuke】

Yun Lie inexplicably traveled to the world of pirates, and there are two news: bad news, he is not dead.

Good news, I’m lucky, I start with a devil fruit, and it’s a space fruit with extremely high lower and upper limits!

The powerful ability of the fruit gave him the confidence to go out to sea for adventure.

【Don't be a pirate】【With brain】【Multiple female protagonists】【Half-invincible】

The protagonist Moonlight came to the world of pirates and was invited by Luffy to board the ship. The East China Sea, Winter Island, Alabasta, Sky Island, Naga Island, Water Seven Cities, Judicial Island, Thriller Bark, Sabaody Archipelago, the Battle of Marineford, etc. With the joining of the protagonist, everything will be different.

When he woke up, Ji Dan found himself traveling to the world of Game of Thrones!

The dog system deserted the battlefield, abandoned me, left a big gift package for beginners and ran away.

When the cold wind of winter blows out the flame of life, the undead undead carry the cold wind south to the Great Wall, but what does that have to do with me?

I pilot the magical ship - the Nemesis!

The dragon head on the prow is raised high, and the magical dragon flame opens up a new route...

…It might not be very enjoyable at first, please watch patiently.

She was once the most sorrowful god in Teyvat.

Fukaros saved the people of Fontaine at the cost of the collapse of her divine throne, but in the last moment before her consciousness faded, she was swept into a deep-sea vortex by a monstrous wave—when she opened her eyes again, she found herself in an unknown world.

"Devil Fruit? Cursed Sea?"

The Celestial Dragons raised their shackles, intending to enslave the mermaids; the Four Emperors' warships crushed the coral palace; and thousands of meters below the ocean, ancient sea kings were gnawing at the sealing chains…

When the scales of judgment sink into the blue sea:

With a flick of her fingertips, the seawater of her womb transformed into a god-slaying weapon, engulfing Mary Geoise;

She wept and murmured, "The law can reforge the Seastone and suppress Blackbeard's Tremor Fruit."

She stood atop Noah's Ark and proclaimed to the four seas: "My name is Fucarus—this ocean will one day be restored to justice!"

...

Donghai, Windmill Village.

Funina: "Huh? I'm the Water Goddess! Really or not?"

(I wrote this as soon as I thought of it, and I'm running two instances at once!!)

He transmigrated into Marco's body, starting with the Marineford War. Knowing the plot, Marco understood that the Marineford War was a dead end, but fortunately, he had a stat-adding system and knew the story, so everything could still be changed... (He had a girlfriend but no master).

Bad news: Journeying through the world of pirates, you’ll start at the execution ground in Rogue Town, about to be beheaded!

Good news: The [Devil Fruit Synthesis System] has been activated, turning everything into a material!

[Rusty Iron Filings] + [Seagull Corpse] instantly synthesize the [Zoology – Slashing Bird Fruit]!

Slash through the scaffold and escape! From now on, I rewrite the rules of this sea!

While others scramble for a Nature-type fruit, Fang Yuan sets his sights on the Four Emperors.

Kaido’s dragon scales? Perfect for synthesizing the [Mythical Beast – Lava Dragon]!

Whitebeard’s vibrations? Decompose them into the [Concept – Space Tearing]!

Blackbeard can hunt with the Fruit? Sorry, I command an army of three thousand users with special abilities, producing the fruit on an assembly line!

Years later, when Fang Yuan reigns supreme in Marijoa, the Five Elders realize in despair that they’ve provoked the most terrifying power in this sea… the source of power!

Lu Zhong got the hunting space system.
