[Unbeatable background, no system, multiple female characters, doesn't eat beef]

This book is also known as [One Piece: The Strongest Background King] and [Because I don't eat beef, Im said I'm too extreme].

Ace's father was the Pirate King Roger, Luffy's father was the Revolutionary Army leader Dragon, and Teach's father was the former ruler of the seas, Rocks.

Alright, alright, so the world of One Piece has entered the era of relying on one's father's connections, huh!

My name is Narona Ian Saint. My mother lives among the flowers year-round. The Five Elders kneel and call me Young Master. The Knights of God are my personal guards. What do you have to fight me with?

Comparing family backgrounds? My family has a history of 800 years, but it can't compare to your family's three generations of hard work.

"Kicking the Celestial Dragons like a football? Who is this guy to be so arrogant?!"

"What? The Five Elders actually called him Young Master? Then it's alright!"

"They kidnapped Princess Vivi to the Holy Land, and then blew up a restaurant just because she wouldn't eat beef. Is there no law left?"

Ian: "Which law says you can't do whatever you want? I'll make my mom change it!"

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.

Luen journeyed through the pirate world, gaining access to the most powerful stat system, allowing him to plunder other people's stats. Looking at the golden stats on the Deserter King Coby, Luen exclaimed, "You clown, you deserve it? Take it!" Then, Luen plundered even more powerful stats. Marine Headquarters: "He is a monster capable of devouring and robbing everything, the most vicious esper in history. Without permission from the highest levels of the World Government, you must not engage him! The world's most dangerous man! 'King', Luen! Live or die! Bounty: 3.9889 billion berries!"

Transmigrating into the world of the "Hakoniwa" (Little Garden) in the world of crossover anime, Izayoi Sakamaki, while waiting for her invitation to the Little Garden, was invited to the Multiverse Chat Group and became its strongest member. Esdeath: "Izayoi, I will definitely not let you leave me too far behind!" Rikka Takanashi: "My contractor, following the ancient oath..." Nagatsuki: "You are hundreds of times stronger than the True Ancestor!!!" Touhou Project: "Um... Boss, do you have any extra Third Star Particles? Can I borrow some?" Gilgamesh: "I, the King, declare you the strongest!" Brunhilde: "Lord Izayoi, please save humanity!" Izayoi Sakamaki: "Thanks for the invitation, just arrived in the Little Garden, challenging the Celestial Theory." With her absolute power, Izayoi Sakamaki also became the chat group's sole administrator...

In the Sword Art Online world, Seiya, the champion of the National Kendo Tournament, is Kirito's lifelong rival. In the Prince of Tennis world, can a mere killing tennis ball be considered impressive? Let me show you what tennis that destroys the world is! In the Children's World I Recommend, a child star debuted and became a top martial arts star in the entertainment industry! In the Jujutsu Kaisen World, he is ranked first on the Two-faced Sukuna List! In the To Be Determined World, there are the Naruto World, the Pirate World, the Bleach World, the Valkyrie of the End, and so on...

After traveling to the Little Garden, Su Jin, who had just gained the godhood and became a quasi-god, suddenly saw a forum invitation in his eyes.

Kocho Kanae: How to kill Muzan Kibutsuji at night?

Aizen Kusuke: How to remove the Hougyoku from Rukia Kuchiki's body?

....

Questions popped up one after another, and Su Jin subconsciously answered: Thank you for the invitation, I am in the Little Garden, I have just become a god, and it involves people in the circle, so the answer has been anonymous.

A new book is released, the title is "Let You Go on a Love Variety Show to Get Blackmailed, You Go Crazy and Become Red" - Takasaki traveled through the Naruto world for 3 years and finally got a system that can make him stronger by writing in a diary. Anyway, no one else can see his diary, so he just writes freely. But gradually, he felt something was wrong. Why is Hinata normal when facing Naruto, but blushes when she sees him? Sakura is obviously Sasuke's straight female licker, why does she smell like tea for no reason? Even in winter, teacher Yuhi Kurenai only wears ultra-short shorts to show off a pair of beautiful legs and wanders around? Ino, who always has a hot temper, is as gentle as a kitten who can only speak coquettishly? Tsunade always finds excuses to stay drunk at his house, and she doesn't even

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?"

I traveled back to the day Konoha was founded and awakened a fancy sign-in system.

He signed in to Konoha Village as an ordinary person for fifty years.

It has everything: martial arts techniques, ninjutsu, bloodline limits, Demon Slayer breathing techniques, One Piece Haki, and more.

Due to his cultivation techniques, Thousand Hands Immortal has a long lifespan and grows younger with age, earning him the title of "Immortal Master" among the villagers.

The villagers didn't know until the night the Nine-Tailed Fox attacked the village and Thousand-Handed Immortal descended from the sky.

There is still an immortal god in Konoha!

At the same time, a cold, mechanical voice echoed in Thousand Hands Long Life's mind.

"Ding! Triggered the event check-in. Successfully checked in on the night of the Nine-Tailed Fox's attack on the village. Congratulations on obtaining: Multiverse Chat Group!"
