Gu Changtian accidentally travels to the world of One Piece and is bound to the One-Punch Man Summoning System. In the One Piece world, he establishes the First Legion and continuously accumulates shock points.

Such a terrifying demon has crossed over into the world of One Piece. What will become of the One Piece world...?

"The Warring States period was terrifying; the First Legion members were all like monsters..."

Whitebeard: "Giants are the strongest men in the world..."

Redhead: "Oh no, my pride isn't working anymore..."

Garp: "Even my iron fist can't beat the First Legion..."

Kizaru: "No matter how much money you offer me, I won't fight the First Army..."

Ryan, who survives by petty theft after transmigrating to the world of One Piece, looks at the Devil Fruit he just stole and says:

He who steals a hook is executed; he who steals a country becomes a prince… he who steals heaven and earth becomes a saint!

From now on, please call me the Demon Lord of the Heavenly Thief!

"Is there something wrong with the story of an ordinary person like me being reborn as a character in One Piece, only to be born on a ship and shipwrecked, ending up on Elbaf Island?" "What?! I transmigrated too early!?" — (Multiple female leads, no system, single world, multiple transmigrations)

Link, transported to the world of One Piece, brought Doraemon's magic pocket with him. He happened to run into Luffy, who was still using the Gum-Gum Fruit and hadn't yet awakened his true power as the Mythical Zoan type, Sun King form. So, I'll follow this future Pirate King, the liberation warrior Joy Boy, the future Sun King, and experience the magnificent world of One Piece together! During their journey, various gadgets in Link's hands will demonstrate their powerful effects! Luffy, did you know the Gum-Gum Fruit has another name? Hawkeye, you're the world's strongest swordsman? How about the [Famous Sword - Lightning Bolt]? Kaido, you have the strongest Zoan-type army? I have some delicious [Momotaro Rice Balls] here, you can try them! Im, you want to destroy the world? Here's the [Earth Destruction Bullet], do you want it...?

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")

Akainu, the boss, was furious: "Levi! If you slack off again, I'll send you to the New World!"

Levi turned over and said, "Marshal...it's so troublesome. The journey is too far...I'm too lazy to go."

During the Battle of Marineford, the world was collapsing and the sky was breaking, but he was sleeping soundly under the execution platform.

A fatal attack came at him, and he turned over unconsciously... Boom! The attack was gone!

Marshal Zhan Guo collapsed, holding his head. "Quick! Wake up Levi! Let him finish the fight before he goes back to sleep!!"

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

In the year 1480 of the Haiyuan calendar, during the Rocks era, Luo Zhen, who lived in the same era as later legends, had been reincarnated into this world for twenty-three years and traveled the world as an adventurer.

When the day came when my cheat code was successfully loaded, I discovered that this system had too many functions, integrating lottery, summoning, and strengthening.

However, once he received the novice gift pack, a white light flashed, and the figure that appeared in the magic circle turned out to be a villainous woman who left a deep impression on him...

Red hair ponytail, golden eye circles and that magical charm...

Quack! It's Miss Makima, the ruling demon!

In the future, more and more wonderful partners will appear one after another - such as the witch cursed by love, King Arthur can't be a girl, the loli with legal super powers, the universal angel for entertainment, the big fat sheep of the ninja world, the ice general...
