(Smart general + invincible + reasonable plot + no collapse of combat power)

After defeating Kabuto Yakushi and lifting all the Impure World Reincarnation of the Fourth Ninja World War, Itachi, who was burdened with countless darkness and contradictions, completely conveyed his will and love to Sasuke and left the ninja world without any regrets.

But just when Itachi thought that everything was over, he regained his 18-year-old body and came to the bottom of the Sabaody Archipelago in the pirate world!

"The Age of Discovery? Thousand Sunny?"

"You want to go to Fishman Island, 10,000 meters below? And find the end of the Grand Line?"

"You want me to be your companion?"

Luffy smiled and waved at Itachi: "This is truly a fate given to us by God, Tear Groove Man, you must be my partner."

Zoro: "Although I don't know this guy's origins, he is quite reliable."

Robin: "I am very interested in him. Maybe he is carrying a destiny that he himself does not even know about."

Akainu: "K-sou! Put a bounty on that man. Itachi Uchiha's head is worth at least 3 billion!"

Garp: "Hahahaha, I don't know where this guy came from, but the giant he summoned is really cool."

Ryan was reborn in the world of One Piece. His parents are unknown. He was picked up and adopted by an old man. Fortunately, he was born with Observation Haki. The most important thing is that Ryan is also bound to a god-level cooking system. The cooking levels are divided into general, fine, excellent, top, master, unparalleled, and god-level. He even conquered Rocks with his cooking skills. In order to upgrade his cooking skills, Ryan joined the Rocks Pirates. When Whitebeard, Golden Lion, Kaido, Big Mom... these legendary pirates boarded the ship one by one, they found that this pirate group was really a paradise for gourmets. Ryan, as a cook, became the vice-captain of the Rocks Pirates. ... Steel Bone Sora: "If Ryan, this guy, wasn't a cook, his bounty would probably be higher than Rocks!" Garp: "Sooner or later, I will capture this guy Ryan and bring him to the Navy Headquarters to be a cook!" Protagonist: Ryan

Luo Lan traveled to the world of pirates, but the golden finger cheated him, it seemed useless.

Fortunately, I met Luffy at the beginning, and I planned to hang out in the hat group and wait for the finale.

But what he didn’t know was that after reading his comics…

Luffy frantically racked up experience in the comics and awakened Nika form ahead of time!

Zoro had just finished his duel with Sasaki Kojiro in the morning, and he fought Kenpachi again in the afternoon!

Sanji hangs out with guys with thick eyebrows all day long, shouting about youth, passion and so on~

Usopp asked the two Wang Yue to create a shallow sword, awakening the bow and killing star!

Chopper gathered the power of the twelve beasts to prove that I am not the weakest fruit of everyone!

Robin’s thousand hands formed a seal at the same time, and told you what is the spiral pill washing the ground!

…

When the top war comes, the *hat group makes a strong debut and shocks the world! !

Dande Shache, who suddenly traveled to the sea and became a naval captain, was not interested in the so-called justice of the navy. He just wanted to hide in the East China Sea and become a warlord.

He had only one goal.

That was to build high walls, store up food, and slowly become king.

Then.

Overturn this world
