Yuro transmigrates to the world of One Piece and becomes bound to a super check-in system.

You start by obtaining a physique enhancement pill and a Logia-type Devil Fruit.

Yuro broke into Beehive Island, gained Rocks' approval, and won the praise of Whitebeard and Shiki, eventually joining the Rocks Pirates.

From then on, the Rocks Pirates gained a new strongest fighter, possessing the strongest physical skills, the strongest Devil Fruit, the strongest swordsmanship, and the strongest Haki.

Rocks: Yuro, I call you the strongest!

Whitebeard: The strongest man in the world? That's that guy's exclusive title!

Roger: I am not as good as Yuro, he is the true king!

Garp: I'm tough enough, but he's even tougher than me!?

Bai Yu came to the Naruto world as a second time traveler from the wizarding world.

The "Book of Ancient Sound Magicians" in his soul made him see the possibility of becoming a high-level wizard.

......

Although the fireball is powerful, its flying speed is not as fast as the improved level 0 spell [Acid Missile].

When the Impure World Reincarnation meets the [Soul Binding Technique] and the Flying Thunder God encounters the [Dimensional Lock], who is stronger?

......

"As we all know, wizards are all-encompassing, and sorcerers are a branch of wizards. So it makes sense that I know some ninjutsu, right?"

After saying this, silver-white scales grew all over Bai Yu's body, and he turned into a giant snake.

"The universe is vast, but I only take one bite!"

Blood and sweat intertwine to create a unique flavor unique to men, and the collision and friction of fists create a passion as dazzling as sparks!

Animal type, Bull-Ox Fruit, Mythical Beast, Bull Demon King form. When you're tough enough, there's no enemy you can't tire yourself out of.

Panting, Six Paths Madara said: "I, Uchiha Madara, would like to call you the meatiest!"

Didiski Xia Zheteng couldn't understand it at all. He was just watching the excitement, how did he end up transmigrating to the world of One Piece? And even awakening some kind of "spectator system"? But watching the excitement was really fun. So, wherever there was a big spectacle in the world, there was bound to be a Marine Vice Admiral who didn't care, didn't intervene, didn't catch thieves, and always had a watermelon and claws. "Enies Lobby is about to be breached, Vice Admiral, make your move!" "No rush, let's watch the excitement." "The prisoners at Impel Down are about to escape, Vice Admiral, make your move!" "What's the panic, let's watch the excitement." Sengoku: "Xia Zheteng, if we don't act soon, Ace will be rescued." "Oh, I really have to join in."

Q: How do I win Tsunade's heart?

A: All you need to start is a piece of candy, plus a little bit of good looks, a little bit of composure, a little bit of humor, and a little bit of strength.

Q: Is it a tiny bit?

A: If that's what you think, there's nothing I can do. (The bear shrugs)

Q: Did Tsunade commit domestic violence after marriage? After all, her superhuman strength could shatter Susanoo.

A: No, I don't think so. I do often... Anyway, Tsunade is very well-behaved and sensible. (Hands on her lower back)

Q: As the Fourth Hokage, the chairwoman of the Konoha Group, and the God of Gamblers in the ninja world, do you feel a lot of pressure being with Tsunade?

A: Not at all, after all, I fulfilled my dream and became the Hokage!

Lin Yu transmigrated to the world of Demon Slayer. Awakening the Character Inheritance System, he immediately inherited the legacy of the blind swordsman, Fujitora Issho. Thus, a swordsman of unparalleled skill and mastery was born… “This swordsmanship!” “Is this really a sword that a human could wield?!” Kibutsuji Muzan collapsed to the ground, his face filled with unprecedented terror. Kibutsuji Muzan once again experienced the terror of being dominated by that figure four hundred years ago, even more terrifying than before. “This oppressive feeling…” “Perhaps, compared to us, you are the monster.” Upper Moon One, Kokushibo, stared intently at the man standing before him.
