One Piece: The More Beauties Around Me, the Stronger I Get

【Invincible + many women + ruthless and decisive + no allegiance】 Ridiculously handsome Lin Hao is a college student. After overexerting himself on a date with a rich older woman, he wakes up to discover that he's arrived in the world of the Pirate King. Fortunately, he gets a “Partner” System. Every time he successfully gains a female partner, he receives a reward. From then on, Lin Hao ventures farther and farther down the path of finding partners, growing stronger all the while. Garp: “What? He's so young, and he's already become the Fifth Emperor?” Kaido: “Hahaha! He's the only person in this world who can take one of my basic attacks and live.” Big Mom: “You've got to be kidding me! Is this guy reproducing even faster than I am?” (Just so you know: The protagonist doesn't fawn over anyone, and he even beats up the Straw Hat Pirates. If that bothers you, don't read.) I'm no good at writing blurbs, so please check out the story. (*^▽^*)
