Will travels through the pirate world.

He is chased by the devil fruit ability user at the beginning. How can he, an ordinary person, and a dying deer deal with it?

Ding!

Congratulations to the host for activating the extremely serious psychological shadow system of the genius doctor saving people.

Saving people and causing psychological shadows will randomly gain an ability from the other party!

Will: Σ( ° △ °|||)︴

Good news, there is a system. Bad news, the system is useless!

…

In the war at the top, everyone looked at Ace who had been pierced, and their eyes were full of tears!

Will: "Hold your tears, hold them first, it's just a fatal injury, there's still hope."

Not long after, looking at the Whitebeard members crying loudly because of Whitebeard's tragic death, Will spoke again.

"Hold your tears again, hold them again, it's still possible to save him, it's still possible to save him!"

From then on, Will began his pretentious way.

Aokiji: "I have a broken leg in my hand, he told me to eat whatever I want to supplement, should I eat it?"

Whitebeard: "This kid is a thief of welding, don't ask me how I know!"

Kizaru, who was in charge of hunting Will, thought it would be easy to hunt a doctor?

But at this time, he looked at Will who was suffocating him with his domineering color, and a thousand horses galloped through his heart.

"You told me this is a doctor?"

"Second uncle, I can also cure my facial paralysis, come and try it, right?"

(Devil Fruits + Haki + hand-to-hand combat; dual strong leads)

A teenage boy transmigrates into the vast world of pirates and refuses to accept a world ravaged by them: “Let me save it.”

Kaido, beaten down by his fists, admits, “As expected, Haki stands above all. Noah, kill me.”

Hawkeye Mihawk, battle intent surging: “Noah, let me witness the spirit of the world’s strongest.”

As Pangaea Castle begins to crumble, Noah declares to the world:

“It isn’t—nor should it be—the pirates who save the world, but the Marines. And I’ll tell you this: the Celestial Dragons will bleed, and they will die.”

Su Chen traveled to the pirate world with a magician's inheritance.

After learning most of the magic, he met Luffy who had just set sail and accepted the invitation from the future Pirate King.

What kind of collision will occur between the gorgeous and magical magic and those magical devil fruits?

Nami, come here, let me strengthen your wind-type celestial magic!

Usopp, do you know about the magic bow and various attribute ammunition?

Sanji, do you want some top-quality ingredients from around the world? And some invisibility magic?

Hey, Robin, everyone has their own meaning of existence. If you don't even have the courage to try, you don't deserve happiness at all!

After being strengthened by Su Chen, would Luffy and others still watch Ace being killed during the Battle of Marineford?

All regrets will be made up!

Luo Lan traveled through the pirate world, becoming captain of the Whitebeard Pirates' Squad Zero and activating a god-level manga system. He knew full well the fate of the Whitebeard Pirates at Marineford. So, he retreated to gain experience and improve his own strength. With the Battle of Marineford imminent, Whitebeard needed a period of intensive treatment due to health issues, so he temporarily appointed Luo Lan as acting captain of the Whitebeard Pirates. Months later, when Whitebeard completed his treatment, he was utterly stunned! Marco: "The Undying Flame is the true way to activate the Phoenix Flame!" Jozu: "Eighth Death Gate, open! Who can withstand my [Night Jozu] move?" Vista: "When I master the dual-sword style, my Zanpakutō, Nosei, that's when you prepare your final words!" Little Oz: "The super-multiplication technique in Butterfly Transformation Mode is so fascinating!" ... Whitebeard: "I asked you to temporarily take charge of our group, and you've actually raised the captains' strength to that of a general?!!"

The era of the great pirates.

The sea is surging, the strong are destroying the sky and the earth, and they are fighting each other. It really makes people——

Can’t get up!

I, Rusilu Cullo, twenty-four years old, my biggest dream:

Live this life safely!

Travel through the world of pirates, carrying a treasure appraisal system with you. An apple was identified as a Devil Fruit. A gold coin was identified as a Destiny Coin, which can withstand three fatal attacks. Ace's necklace was identified as the Entei Necklace, doubling the wearer's fire power. The beads can be manipulated to transform into giant fireballs that chase enemies, and any enemy hit with the beads restores health. The Alabasta Golden Scepter was identified as the Horus Scepter, allowing two or more Devil Fruit-bearing objects to exchange their Devil Fruit abilities. This can only be used once! Smoker's cigar, Nami's weather stick, and Usopp's slingshot all underwent dramatic transformations after being identified. So much so that Im exclaimed, "A fruit even more powerful than the Sun God Nika has appeared!"...

All Things of this World, Turn to Ashes, Flowing Blade-like Flame!

Crossing over to the world of pirates(the one piece world) , in the era of pirates, the Roja from eleven years ago obtained a Sword Soul system that lets him strengthen infinitely and extract various kinds of skills.

Flowing Blade-like Flame (Ryūjin Jakka) , Mirror Flower, Water Moon (Kyoka Suigetsu), Moon Fang Heaven-Piercer (Getsuga Tensho), Thousand Cherry Blossoms (Senbonzakura)……

“If this sword descend, you may be roasted to death.” Roja looked at Akainu in front of him and seriously said.
