Review Detail of Celleborn in One Piece: Starting by Refusing Shanks

This story is interisting and all, but I getting tired of the MC personality, in the beginning was funny but now his bored attitude is getting annoying. At least have some sense of wonder, the dude travel to a fictional universe full of fantastical shit and call himself a traveler but in no point he seems to be enjoying any of it, he is just in autopilot going where the system point him to, he barely seems to care for the power ups he is getting. I not even saying that he should be a happy-go-lucky guy just give him a goal or something, show that he is traveler because he want to explore and see the wonders of the one piece world. Ok, final thing, please have any bartender deny him a drink, at least one person in the world should tell the 10 year old kid "no" when he enter a bar alone asking for booze.
