In the year 1462 of the Sea Calendar, 13-year-old Yudian enrolled in the same school as Garp and Sengoku, only to be utterly defeated in the Marine Headquarters training camp. In this world of talent and Devil Fruits, Yudian could only rely on hard work and the system. 'Ding! Host needs to run 100,000 laps around Marine Headquarters to reach the maximum level of Six Styles - Shave!' 'Ding! Host needs to poke stones 1 million times with his fingers to reach the maximum level of Six Styles - Finger Pistol!'... 'Ding! Host needs to smash 10,000 mountains with Armament Haki fists to reach the maximum level of Armament Haki!' 'Ding! Host...' Listening to the system's repeated prompts and those ridiculous training tasks, Yudian felt immense pressure! However, after defeating Whitebeard with a single punch, the force of his punch blowing away Shiki, and his power intimidating Roger, he realized that his previous hellish training was indeed worthwhile.

My name is Uchiha Mirai, a transmigrator!

I had just arrived in the Naruto world and hadn't even figured out what was going on when the system sent me to the One Piece world. But I panicked because this is Ohara!

Fortunately, the system bound it in time!

[Ding! The "Many Children, Many Blessings" system is being bound!]

The higher the score for the opposite sex, the greater the reward!

[Ding! Congratulations to Nicole Olvia on the birth of her child. Reward...]

Join the crew and witness the world of One Piece together with the Straw Hat Pirates.

Martial arts expert Lin Ning's soul transmigrates to an unfamiliar ocean world, becoming a young man from the East China Sea.

Relying on his martial arts will from his previous life, he awakened Conqueror's Haki upon waking.

He learned Conqueror's Haki Entanglement, encountered Luffy who had just set sail, and joined the Straw Hat Pirates.

He combined his past life's martial arts to create a body-forging method, and worked hard to improve alongside Luffy, Zoro, and others.

While cultivating their skills and exploring the truth of this world, they embark on unknown adventures with new companions.

As the sea breeze rises, their legendary journey begins!

After his defeat on Onigashima, Kaido, submerged in the seabed's lava, opened his eyes and was reborn in 1484, serving as a trainee on Rocks' ship. The God Valley Incident was about to unfold! "One bad thing after another. If defeat by Joyboy is fate, then I will tear it apart!" Kaido picked up the Eight Saber Rings, and with a wielding of his Domineering Haki, he blasted the mountain to smithereens. A Devil Fruit awakened? Enveloped in Domineering Haki, he could see and kill! Only Haki could forever stand at the top of the world! In this age of brilliant heroes and powerful warriors, Kaido must rely on his own strength to challenge Roger and Whitebeard and make up for the regrets of his past life!

When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

[Unbeatable background, no system, multiple female characters, doesn't eat beef]

This book is also known as [One Piece: The Strongest Background King] and [Because I don't eat beef, Im said I'm too extreme].

Ace's father was the Pirate King Roger, Luffy's father was the Revolutionary Army leader Dragon, and Teach's father was the former ruler of the seas, Rocks.

Alright, alright, so the world of One Piece has entered the era of relying on one's father's connections, huh!

My name is Narona Ian Saint. My mother lives among the flowers year-round. The Five Elders kneel and call me Young Master. The Knights of God are my personal guards. What do you have to fight me with?

Comparing family backgrounds? My family has a history of 800 years, but it can't compare to your family's three generations of hard work.

"Kicking the Celestial Dragons like a football? Who is this guy to be so arrogant?!"

"What? The Five Elders actually called him Young Master? Then it's alright!"

"They kidnapped Princess Vivi to the Holy Land, and then blew up a restaurant just because she wouldn't eat beef. Is there no law left?"

Ian: "Which law says you can't do whatever you want? I'll make my mom change it!"

[One Piece Fanfiction] + [Invincible Male Protagonist] + [Decisive and Ruthless]

Starting in God Valley, facing a three-way battle between the Navy, Roger, and Rocks, Lynn, a slave, makes a fourth choice—to devour the era!

Having obtained the power of the Mythical Ancestral Dragon, he not only didn't run away, but instead kidnapped the sea overlord, Rocks!

Thus began an unprecedented path to hegemony.

He doesn't want to be the Pirate King because the entire ocean will be his territory; he doesn't want to be a revolutionary because he wants to establish an order even more absolute than that of the Celestial Dragons!

"Im, get off that throne! From this day forward, I, Lynn D. Caesar, am the one and only king of this world!"

Sarred Doug, upon transmigrating, found himself at the scene of a gang war. Just as he was struggling in agony, the Interception System arrived, and Doug relied on it to grow stronger step by step!

God Valley saved Teach, thus changing the course of the world and rewarding him with the appearance of a king.

He intercepted the bear and Ginny, changing their tragic fates and obtaining the Twelve Supreme Grade Swords, Aragami!

They intercepted the Azure Dragon Fruit, stripped Kaido of his title as the strongest creature, and rewarded him with an extremely powerful physique comparable to that of an ancient giant!

They intercepted Barrett, a descendant of a demon, and Barrett ate the Azure Dragon Fruit, which rewarded him with Conqueror's Haki: Voice of All Things!

The Marineford War changed Ace's inevitable demise, rewarding him with a special application of Conqueror's Haki—a punishment! Specifically designed to counter Im's immortality!

A man of sound mind, Whitebeard Jr., under Whitebeard's leadership, participated in the Marineford War!

Teach became the executioner's blade in the slaughter of the Celestial Dragons!

Doug's influence has spread to the underworld, the CP organization, and the pirate faction.

He recruited the Whitebeard Pirates to build the world's strongest pirate crew, punching the Marines, kicking the Five Elders, and even holding off Uranus!

Little Im! Hold on tight! Hold on tight!

Lu Ming traveled through the pirate world and unexpectedly obtained a god-level lottery system!

You can extract skills and items from all the heavens and worlds:

Who has the strongest physical skills in the Eight Gates vs. Hero Garp?

Who is faster, Quicksilver or Kizaru with the Pika-Pika no Mi?

Which one is the strongest Haki, the full-level Nine Yang Magic Art or the Armament Haki?

With the system in hand, the world is mine!
