[Pirate faction] [Slow burn] [Gradual growth] [User of the Nen-Nen Fruit] [Great swordsman] [Powerful user of all three types of Haki] [The Float-Float Fruit is fake] [No female lead]

Hey hey hey~~

Golden Lion: Roy, why isn't my Float-Float Fruit as strong as your Mind-Mind Fruit?

Roy: How should I know?!

Barrett, Mihawk, Tezzo, Crocodile...

Hurry up and get on the ship.

Roy arrives in the world of One Piece and discovers that the future powerhouses are still young.

They lured them all onto their own boat, one by one.

When Luffy set sail, Roy looked back and exclaimed, "Oh no! I've become the world's ruler!"

When Luffy arrived in the New World, Roy looked back at his team and said, "Brothers, you guys go first. I'll see what this guy is all about."

[No Harem] Chu Tianqing, an emergency doctor, traveled back to the Zhenguan period of the Tang Dynasty because of a medical dispute. With his modern medical knowledge and a system called "Modern Community Hospital", he became a miracle doctor in the Tang Dynasty.

Chu Tianqing: "Your Majesty, your blood pressure is a little high!"

"Minister Fang, your blood sugar is skyrocketing."

"Duke Su, I always thought you had fat-packed muscles. It turns out your blood lipids are pretty high!"

Having spent many years in Naruto, he diligently trained, but due to his ordinary talent and lack of system assistance, he could only become an ordinary special Jonin of Konoha. This was probably the pinnacle of Gen Takuno's life. But... Gen Takuno looked at Hiruko, who was attacking Kakashi who had just obtained the Sharingan. It seemed that everything had reached a turning point in his fate. Oni-Garra Technique!

Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(This book is also known as: "I Resell Supplies in the Heavens" and "After Accepting Tanjiro, I Became the MVP of the Demon Slayer Corps")

Many years later, facing the disaster that swept the world, people couldn't help but recall the day when the Rocks Pirates collapsed. At that time, everyone thought that the world would return to order, but it was not until much later that people realized that a real monster began to devour the world from that day. Roya, who traveled to the pirate world, accidentally gained the ability to transform into Qiongqi. Qiongqi is a fierce beast that accompanies natural disasters, so he can create natural disasters; Qiongqi is an evil beast that punishes good and promotes evil, so he can control man-made disasters. As a result, the world ushered in a real disaster. "Sorry, I'm not here to bring peace to the world, I only let the world use swords." Roya said. Everything started with an intern in the Rocks Pirates.
