(One Piece + no system + half time travel + no devil fruit + single heroine + invincible comedy + slow burn + non-pirate + non-navy)
(The story is set in the parallel world of One Piece. In this world, the protagonist's time travel disrupted time and space. Momonosuke failed to travel through time and died in the war in Wano. The protagonist also lost his memory due to the time travel accident.)
The Kingdom of Flowers has been hiding its clumsiness for so long that those Tianlong people can't distinguish between the big and small kings, and they are a bit embarrassed.
I, Wu Cang, the young master of the Kingdom of Flowers, will lead the army of warriors from the Kingdom of Flowers to the Red Earth Continent, trample the holy land of Mary Joa, point at Im's nose and loudly announce: "Grandsons of the Heavenly Dragons, your grandpa from the Kingdom of Flowers is here!"
But the ideal is very full, and the reality is very skinny. I want to make a name for myself, but I am surrounded by big guys. When will I be able to stand out?
(The protagonist will become stronger when he meets the characters in the One Piece plot. In the early stage, he made little progress in the West Sea. After entering the Grand Line, he developed the real effect-fruit mutation)
