He traveled to the world of One Piece and stole the Op-Op Fruit right from the start.

Lynn unlocked the true use of the Operation Fruit.

Observe Germa's bloodline factors, optimize skeletal defense, and master the Corpse Bone Vein.

Observe the weak electrical currents within the body and control the chaotic body movements.

Observe the abilities of the Swallow Fruit, optimize the five internal organs, and master the Six Treasures Immortal Thief.

...

Through the use of the surgical fruit to strengthen bones, skin, and genes, a god-like figure was born.

The most amazing thing is that Lynn can use the Op-Op Fruit to enhance his crew into monsters as well.

Boa Hancock: Ever since Lynn healed my Sky Dragon Mark, I have been Lynn's woman.

Blackbeard: My Dark-Dark Fruit is not the strongest Devil Fruit; Lynn's Op-Op Fruit is the strongest.

Kaido: I am not the strongest creature on land, sea, and air. Lynn is the strongest creature!

The Five Elders: Joy Boy is not the sun god; Lynn is the true sun god.

Im: You're wrong. Lynn is the real god of this world.

A navy from the Age of Exploration, upholding the ideals of justice. In the Douluo Continent, starting from the bottom. A clash between the Navy's Six Powers, the Three Colors of Haki, and Martial Souls. Wang Li: My talent is average, but that doesn't stop me from being invincible!

First of all, my surname is Uchiha. Hmm... and inside my body is a sealed Sukuna.

Not once did I try to reconcile with Sukuna. Once I confirmed he couldn’t break the seal, I began to ruthlessly exploit him.

With my Mangekyō and Domain Expansion unleashed, the strongest Bloodline Elimination in history was born—

—— Slashing Release!

Without the slightest hesitation, knowing that my acting wouldn’t fool the Third Hokage and others, I fully displayed my true Uchiha nature from beginning to end.

There was no betrayal, and absolutely no clan massacre.

We, the Uchiha clan, will rebuild Konoha from the ashes!

(Not having watched Jujutsu Kaisen is fine—this just borrows some character settings, with some creative liberties. But if you haven’t watched Naruto… why are you even here?)

Because of the fragments of the main god, Sarutobi Toru, whose soul traveled to the ninja world, finally inherited the personal space of the previous generation of reincarnations.

Well, let’s take a look at what legacies they have: T-virus, super holy water, and substitute arrows. The mortality rate is too high, so we dare not use them.

The Book of the Golden Flower, the Great Qian Martial Arts and Taoist Scriptures (Yangshen Revised Edition), and the Book of the Dead (Cthulhu Edition) are all books that one would be either insane or disabled to practice.

The Celestial Crystal Sword, Thor's Hammer, and Somersault Cloud (Dragon Ball version) cannot be used if your character is not up to standard.

"So, this is the only Hormone Fruit I can use?" Sarutobi Toru's face was full of bitterness. In this dangerous ninja world, what should I do? Is he going to rely on... eating gigolos? (Single wearer, no other reincarnations)

When the allied ninja forces were defeated without any resistance, the Otsutsuki realized that what they had welcomed was not victory at all. The real terror had arrived. Akimichi Kamihara stepped forward step by step, the truth-seeking jade shattered in his hands, and the golden wheel of reincarnation exploded into dust. "You call yourselves gods?" Looking at the higher life forms who desperately claimed to be gods in front of him, Akimichi Kamihara asked softly: "Whose gods? Whose kings?" [Infinitely evolving body] [Sword pressure that cuts through everything] [Light-speed movement that transcends time and space ninjutsu] After turning who knows how many Otsutsuki into fruits, Akimichi Kamihara found the remains of Shibai. "No one has stood in the sky from the beginning, not you, not me, not even the gods, but this unbearable vacancy of the throne of heaven is about to end. From now on, I will stand at the top."

[Invincibility + Entry + Starting Immortal Body + Tom Cat Template (Not a cat, please do not enter if you don't like it)]

Tang Mu traveled through Konoha and became an orphan with both parents dead. He thought his life would start in hell, but unexpectedly he loaded the template of Tom Cat and started with three incredible items: [Immortality], [Super Recovery], and [Learning Adaptability]...

Naruto (completed), One Piece (in progress)...

A follower of the ship, a descendant of the Xingyi Thirteen Spears of Chinese martial arts, transmigrates to the world of One Piece.

On this vast ocean where strength reigns supreme, he awakened the [Perseverance] panel:

—As long as you cultivate, you can become stronger!

No bottlenecks!

—There are no limits!

At Luffy's enthusiastic invitation, he joined the Straw Hat Pirates and became a member of the crew.

He combines his previous life's martial arts training system with Luffy, Zoro, and others to diligently train and improve.

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

Lu Yu traveled through time and space as a person and became Lu Jin's favorite grandson. He was taught the three levels of reverse life and Tongtian Talisman by Lu Jin. Because Lu Yu was very interested in the Golden Light Curse and Thunder Method of Longhu Mountain, Lu Jin shamelessly asked the old master for the cultivation method!

But the Wang family unexpectedly found out and joined forces with more than a dozen masters of the Lu family to catch Lu Yu and force him to tell the Tongtian Talisman!

After being killed by Lu Yu, Lu Yu was also seriously injured and unconscious. When he woke up, he traveled to Douluo Continent for the second time and became a child of the same age as Tang San. He was adopted by Jack, the village elder of Shenghun Village!

After practicing the three levels of reverse life in Douluo Continent for three months, he directly had full innate soul power!

And the martial soul he awakened turned out to be - Fantian Yin!

The first martial soul of the Clear Sky Hammer? Not even worthy of carrying shoes for Fantian Yin?

Tang San, the Sea God? Learn about Thunder Method! Seawater is also conductive!

I, who returned from a person, will not be angry with Tang San. I will smash Tang San to death with Fantian Yin first!

Travel through the world of Naruto and awaken the mosquito's supernatural powers.

Absorbing other people's blood and bloodline limits are the most basic things.

Have you seen nano mosquitoes that can modify gene chains?

Have you ever seen a hundred-meter-long mosquito, comparable to a wild beast?

Uchiha Sasuke: "Why can't I beat him, and the honor of being the chief student was also taken away by him!"

Uchiha Itachi: "Stupid... Damn, how come this guy is even more perverted than me!"

Uchiha Madara: "Oh, my great-grandmother Kaguya, this is really a hell, this boy's mosquito is even bigger than my perfect Susanoo!"

Shen Gu Qingkong: "Sit down, sit down. As a time traveler, it's okay if you don't have a system, but your only superpower can't be more impressive. What a fuss."

(For the original work, please refer to the Naruto manga and anime as the standard, including Naruto's personality)

An unknown soul from another world traveled through time and space to Naruto's body, but was devoured by Naruto and learned everything about his own world. Naruto's personality also changed slightly due to the influence of the traveler! Although all the crises in the Naruto world have ended, his future has not ended with the end of Naruto...
