[No System + Devil Fruit ability development + lighthearted + steady growth + no harem]
Yi was strutting down the street, acting all smug. Maybe Heaven had had enough of him, because it sent a truck to take him to meet Grandma. But fate sent him to the world of One Piece instead.
From the start, he fell right onto Momousagi's head and landed face-first in her arms. He thought this would help him build a connection and reach the pinnacle of life,
but the body he'd transmigrated into was pathetically weak.
Fortunately, Yi had a strong will, and thanks to an absurd stroke of luck, he obtained the Arms-Arms Fruit. Little by little, he adapted, piloted a giant robot, and made the most of his time in the world of One Piece.
Many years later:
Gion: “Hubby, you're amazing!”
Sengoku: “You are the true justice that rules the world.”
Zephyr: “As expected of my student.”
The Four Emperors: “Weimas Yi is the true emperor of the sea.”
The Celestial Dragons: “Don't come any closer!”
Meanwhile, our protagonist sat on the Celestial Dragons' throne and sighed. “Sigh... I really didn't want things to turn out this way!”
It's okay, just pay attention to the use of double quotes. For example, I said: "This novel is well written!" The exclamation mark is in it. Yi said: "Peach Rabbit is so beautiful." The period is also in it, instead of just missing it. Always finish talking, that is Yi said: "Peach Rabbit is so beautiful." Peach Rabbit's face turned slightly red. There must be a period in it!!!
