March 15, 63 years of Konoha I seem to be dead [crossed out] I seem to have died and come back to life

March 16, 63 years of Konoha I might as well be dead

April 1, 63 years of Konoha Soul Society is not the underworld of my world, my parents are not here!

July, 63 years of Konoha What kind of Hokage is it? I don't even want to be a dog. Konoha is meaningless. As expected, I still want to be a god of death. Find where the "Soul Society" of our world is. I want to find my parents.

Many years later.

The Lord of the Seireitei, the Captain-General, the First God of Death, the Ten-Tails Jinchūriki, Uzumaki Naruto raised his sword.

"The world should have a more appropriate order."

As a nuclear pacifist, I was awakened when Ace was imprisoned on the eve of the summit.

Pirate world, as your nightmare and the god of death, I will come to the world again.

Sengoku: Whitebeard, I won't kill Ace. Please help the navy fight it!

Red Hair: Oh my, I saw a scary creature. I wonder if you can give me some face and just leave it at that.

Akainu: Damn it, what the hell is this thing? It actually uses my lava as a snack.

Kizaru: How scary! My light is basically just scraping!

Aokiji: Sorry, there's no way I can freeze that guy.

Five Elder Stars: Damn, who released it?

Travel through the world of pirates and start with a human fruit.

We ordinary people are so happy!

Navy reporter: "Excuse me, Mr. Ian, if a normal human eats the Animal-type Human-Human Fruit, is he still a human?"

Ian: "It's a human, but not a human, like a human."

No system, three colors of domineering, double fruit route to build the strongest kingdom. Get the swamp fruit at the beginning, set up your own pirate group, good at success, not adventurous and not passionate, just like to grow in a wretched way. When I first took over this pirate group, the team had not yet formed combat effectiveness, lacked Bailey and lacked personnel. Relying on snatching devil fruits, getting benefits, forming the strongest force, looking for workers everywhere, relying on strength to take over the sky island to build your own territory, and open the strongest kingdom,...

Reborn as Naruto, the Hokage.

He witnessed firsthand how the Fourth Hokage and Kushina were pierced by the Nine-Tails' claws.

Obtain the Bleach Hogyoku system.

Third Hokage: Naruto, do you hate those who bullied you?

They don't hate; they're just afraid.

Kakashi: Naruto is my most important subordinate.

Jiraiya: My Ninja Gaiden, the main character's name is Uzumaki Naruto.

At the hair salon, the shopkeeper asked me to dye my hair black and style it. What, you don't want to? Then I'll dye it black myself.

I dyed my hair black, applied some hairspray, and took off the glasses I used to hide my eyes.

"From this moment on, I will stand in the sky!"

Rocks, Roger, Kuja, Navy, No System, Human-Human Fruit

Introduction:

Lin Xia's dream is to have a comfortable environment and live a carefree life in the navy until retirement.

I leave work before the scheduled time every day, and I get ten days off a month. Life is so carefree.

...

But the Navy Headquarters actually banished Rocks to the West Blue, along with Edward Newgate, Shiki, Charlotte Linlin...

These notorious pirates have all arrived in the West Sea, and Lin Xia's carefree days are over. He roared, "My vacation is gone!"

...

Lin Xia set off for the Navy Headquarters and rushed straight into the Admiral's office.

Lieutenant General Garp laughed heartily: "So you've finally decided to come out of the West Sea?"

Sengoku Vice Admiral's eyes gleamed: "The purge plan can begin. Shall we start with Shiki, or..."

Lin Xia smiled and pointed to the Void Throne of the Holy Land:

"I'm just here to apply for leave. If it's not approved..."

"Then..."

"Take that thing apart."

The Steel-Boned Sky Marshal suddenly stood up and slammed his hands on the table:

"You actually want to demolish Mary Geoise, the home of the Celestial Dragons, descendants of gods!?"

He never imagined that Lin Xia would either not show up at all, or if he did, he would cause such a huge stir!

He actually dares to say he'll tear down the throne—what makes him think he could possibly do it!

Steel Bone clenched his teeth and roared, word by word:

"You just want to take a vacation, right? I approve!"
