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.

Xi Yan, a half-Uchiha and half-Senju, shone during the Second Shinobi World War. While on a mission to the Land of Water, he accidentally traveled to the pirate world and encountered a sea train bound for Judicial Island! Aboard this speeding train, Xi Yan encountered the boy who carried his destiny. Luffy: Are you a ninja? Xi Yan: Yes. Luffy: Be my partner! Xi Yan: Okay... Since we're here, Xi Yan, invited by Luffy, chose to join the Straw Hat Pirates and adventure with them. He used his power to help his friends rescue Robin and save the ship spirit, Merry! Merry: Xi Yan, what's that? Glancing at Moriah, Xi Yan declared that it was a waste of spirit, a waste who only knew how to rely on external things. ...During the Battle of Marineford, the massive Susanoo wreaked havoc on Marine Headquarters...

Life and death battles increase your domineering strength!

Blake (looking up in surprise): "What if he really dies?"

The people at the bottom of this world are struggling painfully. Please work hard to change the world!

Blake (with a puzzled look on his face): "What does their suffering have to do with me? What will I do if they change the world?"

Yim is too strong to be defeated!

Black (reassured): "But there's still Luffy. I'll fight him after he's done!"

Why do you dare to participate in the battle between gods and demons?

Blake (crooked mouth): "I! Have! Hang!"

This is a Gou Dao Tianlong person, get out!

Blake (struggling): "I don't accept it! Why can't the Celestial Dragons just hide?"

One Piece? Great Treasure? Or Change the World?

No, Hu Ci is not interested in any of these.

He just wanted to live peacefully and comfortably until the end of his life...

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.

He traveled through the world of One Piece and awakened the divine skill of manifesting fantasy characters and items.

Kamen Rider Kuuga storms Enies Lobby alone!

Digimon Agumon encounters a young Princess Vivi!

Spirit Detective Yusuke Urameshi (replaced by Raizen) transforms into a demon and confronts Aokiji head-on.

The omniscient and omnipotent Quincy King has descended upon Skypiea!

Multiple sun gods appeared in this world

Nico Robin, who became a Quincy, and Usopp, who gained Nen abilities, had their fates rewritten.

When fantastical characters from all over the world descend upon the world of One Piece, what kind of storm will this sea face?

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.

(Transformation) (Female protagonist) (Invincible) (Various anime/anime series)

Upon transmigrating to the world of One Piece, Li Tian successfully awakens the Fabrication System. From then on, he decides to bring a shocking performance to this distorted world of pirates.

...

During her rescue of Kuma, Bonney's Year-Year Fruit awakened, transforming her into Nika form. She then took all the Yonko-level Seraphim created by Vegapunk under her command, single-mindedly seeking revenge for her father.

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.

(Anime crossover, light novel)

Thanks for the invitation. I'm in One Piece, and I start out as Black Hairless.

Wandering the seas, free and unrestrained, but—

Why is this eagle-eyed rascal chasing me around all day? What? My son offended you? Then go find Xiao Mo! Why are you bothering me?!

Garp, why are you chasing me every day? Huh? Where's Great Britain? Can't you find it yourselves? Inviting me to join the navy? Me, the King of Great Britain, are you kidding me? No way!

Redheads? Giving you face? Not getting involved in the summit? Giving a cripple the run for his money! Asking for a beating!

Huh? I'm not that Black Hairless guy! What does your looking for Black Hairless guy have to do with my Gundam? You've got the wrong person!

I was transmigrated into the body of a Mythical Zoan-type Devil Fruit user?

Before her consciousness was devoured by the consciousness of the Yamata no Orochi Fruit, Xia Lin awakened the Satan Soul, a receiving magic from Fairy Tail that allows her to receive demons.

Xia Lin stated that Devil Fruits are also a kind of devil!

He began by receiving the Yamata no Orochi fruit and became the ruler of Wano Country!

"Wano Country? That name is awful. From now on, this country will be called Inazuma!"

...

Forty years later, when Solo stood before Hawkeye, covered in wounds, he couldn't help but ask:

"A man like you isn't the world's greatest swordsman..."

"You frog in the well, have you ever heard of the 'one-cut wonder' technique?"

I'm a newbie in writing, so please forgive me for not writing very well in the first few chapters!

No group tour, no pirate, no navy, form your own adventure team!

Accidentally dropped the soul of the pirate world, and brought a thunder fruit with the popular system system

After eating the fruit...

Nami: Lei Luo, you bastard, you said you would only marry me and Nokiko?!

Nojigo: A Luo, how much more do you want...

Kuina: So you tricked me into coming aboard, really just to make me the world's greatest swordsman?

In the early stage, the protagonist develops his skills in hiding, and then travels around the world to recruit crew members.

Enter the new world later.

Empress: Lord Lei Luo, you finally came to see me!

Whitebeard: Luo Xiaogui, come and be my son.

Shanks: If you want to be my son-in-law, first ask my Griffin if he agrees...

Garp: Hahahaha... Luo boy, come to the navy, I will guarantee you the rank of admiral.

. . . . . .

When the flag of the adventurer Lei Luo fluttered by... the style of the painting suddenly changed.

"This troublemaker is here again!" "Everyone run! This bastard is here to cause trouble again!"

"Thor, surrender, you heinous criminal!"

Lei Luo's face turned black: "What Thunder God? Don't slander me, or I'll sue you for defamation."
