"That sword style should have been lost to history!!" — Muzan snarled in fear.

"Kamiya Seiichi… you're terrifyingly strong! Are they serious?! Gojo Satoru is the strongest in the modern era?" — Sukuna laughed hysterically.

"Rin, the Sword Saint Kamiya Seiichi is the mightiest Servant! Summon him and we shall win for sure!" — Tohsaka Tokiomi declared resolutely.

"He is the final destination of the sword in this world." — Dracule Mihawk muttered, watching Zoro step up to challenge.

"Eh?! This has to be a joke, right?!" — Kyoraku Shunsui whispered, sweat sliding down his cheek, staring silently at the two blazing Ryūjin Jakka blades.

Sword Saint. God of Cursed Techniques. Strongest Grand Servant. The Pirate Era’s Ender…

Kamiya Seiichi: "All of my strength comes from my own hard work, the system… and transmigration!"

No talent for ninjutsu? Then carve a bloody path with your sword!

Traveling through the world of Naruto, Yongen unexpectedly became an orphan in the Hidden Mist Village.

Without a surname, without chakra talent, unable to practice ninjutsu, and unable to even learn the most basic illusion techniques...

Fortunately, Yongen has awakened the [Proficiency System] - as long as he practices repeatedly, he can become infinitely stronger!

Swing your sword a million times and unlock the title of [Sword Saint]!

Everything in the world will be killed!

Even if one practices Chakra thousands of times without any talent, he can still forcibly upgrade to the Six Paths level!!!

With his physical skills trained to the extreme, Yongen's body even surpasses the Eight Gates of Ninjutsu, and he can shatter Susanoo with a snap of his fingers!

Under the cruel rule of the Blood Mist, he endured and grew up.

"Others practice ninjutsu, I practice swordplay."

"Others learn illusion techniques, I practice swordplay."

"Others are dating, but I'm still practicing swordplay!"

Until two years later——

"The Fourth Mizukage? One sword!"

"Akatsuki? Two swords!"

"Mei Terumi? ...Wait, what did you say? You want to marry me?"

“From today onwards, you will become the Envoy of one of the Main Gods in the Dimensions of Gods. You will travel from one world to another and through that, you will attain what others will never obtain in their entire life.”

The moment these words echoed in Fang Li’s head, Fang Li’s life was destined to be extraordinary…

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Join the main characters as they explore story islands and grow stronger!

...

The synopsis is insufficient; please proceed to the main text, which primarily focuses on the bond between the protagonist and the Straw Hat crew members.

[Naruto + Easy + Fighting] End the war, change misfortune, reject dark text, do not suppress strength, not a single female protagonist, the power system will focus on developing ninjutsu.

Shimizu Mitsuki was accidentally reborn in the Naruto world and became Rin's childhood sweetheart. Facing the ensuing wars, Shimizu Mitsuki was not panicked at all. I have traveled through time, so it is not too much to say that I am dead.

One shot of ten consecutive hits can hit Rokugan, create your own bloodline, and grow infinitely. Two shots of ten consecutive hits can perform a full counterattack, defend against Susanoo, and chop your Tsukuyomi dream into pieces with one sword.

I will protect this Konoha!

Kakashi: Mitsuki saved my life and is my most trusted friend.

Obito: I want to create a world where Mizuki exists.

Madara: You are as strong as Hashirama, but you have more brains than him.

Black Zetsu: My Lord, I created ninja history just to wait for you, Jianyue, to appear. You can protect mom better than I can.

Many years later

Shimizu Mitsuki looked at Momoshiki and his group who came from afar and said: You are the Otsutsuki family.

(Half-funny + scheming + satisfying + doesn't fawn over Konoha + semi-invincible + many girls)

The original female characters who were saved: Mikoto Uchiha, Tsunade, Kushina Uzumaki, and Nono Yakushi...

The protagonist is reincarnated into the Naruto world, and after unraveling the mystery of his birth, he discovers that he has become an adorable Uchiha boy and obtains the Blacksmith System.

In the early stages, he distributed weapons in Konoha; in the mid-to-late stages, he left Konoha and distributed weapons throughout the entire ninja world, watching others get beaten to a pulp.

When others use his weapons, he can also gain the attributes, abilities, talents, ninjutsu, and bloodstains of those people.

Moreover, all those who died using his weapons or were killed by his weapons were taken into his Temple of Death.

They only care about fighting, not putting in any effort; they'll just be brothers inside the Ten Thousand Souls Banner!

He traveled to the world of Naruto and became a four or five-year-old child.

Fortunately, as a time traveler, the golden finger is instantly available, and the "God-level stealing system" can steal and copy other people's abilities.

Even at the beginning, he stole the Wood Release of Senju Hashirama. Since he can steal the Wood Release, then the Sharingan, the Samsara Eye, the Impure World Reincarnation, the Sage Body...

Uchiha Itachi: "You also have Sharingan"

Namikaze Minato: "Your Flying Thunder God Technique is as good as mine. Who taught you that?"

Nine-Tails: "Naruto, it seems that the boy opposite has my brother inside him."

Uchiha Squad: "Impossible, how can there be a second pair of Samsara Eyes in this world?"

Thinking of this, Lin Chen couldn't help but want to go and see the world of Naruto.

But the most important thing right now is to survive.

[Fishing for the heavens, the earth, and all the realms, fishing through countless worlds to slay the heavenly dragon!]

"Ding! Congratulations, host, you have obtained the Supreme Grade Blade - Azure Dragon Crescent Blade through fishing!" (Damage is tripled against dragon-type creatures). Who says Celestial Dragons aren't dragons?

Transmigrating to the world of One Piece, Jiang Yu awakens a god-level fishing system, using a single fishing rod to fish through countless worlds!

While others toil for ten years to hone their domineering aura, he cast his line and caught a [triple-color domineering aura experience pack].

Is the cheap liquor in the One Piece world too unpalatable? A casual rendition of a "god-tier Erguotou recipe" conquers the stomachs of Issho, Garp, Sengoku, and others.

During the Marineford War, Sengoku slammed his fist on the table and roared, "Jiang Yu! Did you lure out the Ancient Weapon Pluton to blow up Marineford?"

From a commoner in the East China Sea to a naval admiral, he swept across the Grand Line by fishing.

He fished out the Azure Dragon Fruit and kicked Kaido over; he fished out the Supreme Sword Heart and cut off Red-Haired Griffin with a single sword strike!

When the Four Emperors' allied forces attacked, he unleashed the [Meteor Summoning Technique]: "Justice? I am the calamity of nature!"

As Jiang Yu stepped onto the Red Earth Continent, fishing line entwined around the remains of the Five Elders: "This world has no need for the descendants of the Creator; it only deserves to remember my name!"

"Since the navy cloak is stained with blood, then let's use Im's head... to wipe it clean!"

[High-octane plot]

East Blue Fisherman → Beats Up Seven Warlords of the Sea → Fights One-on-One Against Four Emperors → Overturns Mary Geoise!

[Outrageous Fishing Scenes]

Fishing out "nuclear cola" to get an old lady drunk, fishing out "100,000 tons of sea stone" to smash and collapse the ghost island!

[Complete Subversion]

Akainu: This kid is crazier than a pirate!

Hancock: How did he manage to steal my stockings?

Im: The first person in eight hundred years to terrify me is a lunatic with a fishing rod!

He was transported to the Naruto world by accident and discovered that he had gained the ability to absorb energy. So he went further and further down the path of searching for and absorbing others.

He absorbed Uchiha Shisui's corpse, gaining some chakra and some ocular power, and acquired the Mangekyou Sharingan, Kotoamatsukami!

Absorb Hashirama's cells to gain a large amount of chakra, and unlock the Wood Release bloodline limit!

He absorbed Naruto's blood and gained the Uzumaki physique and Ashura Chakra!

When he absorbed everything and achieved the title of strongest, the ninja world finally ushered in true peace.
