First of all, let me state that the author is a straight man, and so is the protagonist!
[Fruit+Taijutsu] [No system] [Semi-invincible]
Travel through time and become Portcas D. Ace, the son of Pirate King Roger, and obtain the Burning Fruit.
Developed various strange fire moves.
In One Piece, Luffy always looks ignorant and uneducated, but this has changed since the protagonist traveled through time. Although Luffy can't speak in words, the protagonist will help shape the basic world view from an early age.
Do you have to be a pirate to overthrow the world? Nonono!
This world will be overthrown and rebuilt by our three brothers!
Ps: This is not a mindless and passionate novel. The protagonist does not have Chuunibyou or Chuunisoul. As for the other elements and One Piece, they belong to the protagonist's daughter Amway before time travel. The protagonist has a certain understanding of the plot, but not much (in fact, I am the same), so I will change many of the original settings according to my understanding. If you don't mind, please don't enter.
[Emperor Yan·Falling Heart Flame]: The body continuously generates inner fire, calcining its armed domineering energy all the time. It is known as a one-click cheating tool for practicing armed domineering!
Ps: Although there are a few other elements in it, they are very few. You can easily eat them if you haven't seen others. There are no items from other worlds. Goldfinger can only travel through time.
...
Five old stars? Take my shot [Emperor Yan·The Harmony of Heaven and Earth!
Beyond that, what if Luffy and Sabo were raised as literate people?
Luffy, Ace, Sabo and a group of like-minded lucky people form a force that can overturn the entire world!
