One Piece: The Strongest Conqueror's Haki Joins the Summit War

(Invincible from the Start, Power Fantasy) Yeyu transmigrated into the One Piece world, instantly activating the Conqueror System. By simply signing in every day and soaking up the sun, he grows stronger! There is nothing that a little Conqueror's Haki cannot solve; if there is, then I will release one hundred million times the Conqueror's Haki! Sorry, my Conqueror's Haki is just a little too strong!

Red-Haired Shanks: "Don't you ever dare boast about my Conqueror's Haki being strong in front of Yeyu again. I am so mortified I could die!"

Whitebeard: "With Yeyu around, my Whitebeard Pirates are truly invincible!"

Marines: "Yeyu is coming! Fall back, retreat!"

Sengoku: "Why does someone with combat power as terrifying as Yeyu choose to be a pirate?"

There is no longer any true justice in the Marines, because victory is justice!
