I did drop a novel that i can't remember the name. It's a guy that was a genius but had a car accident and became stupid for a few years and then came back but during those few years he actually spent thousands of years in a cultivation world so when he came to earth he was OP.
It wasn't so bad at first until some black guys went to his mom's shop to rob it and the author couldn't be bothered to give them names so for the whole chapter the MC was just saying "black brother, please stop" and outside of the dialogue, the narrator would just describe them as "black guy said to other black guy".
Even in fantasy novels, usually when the MC gets more powerful his skin turns whiter and I only read a single novel that black skin was not reserved to some kind of sub-human monster and slightly acknowledged the existence of black people as human.
I don't care really if they don't include people of different ethnicities in their novels but its frankly annoying how they insist that whiter is better and black is bad. The only kind of novels you might have a chance with are the kind of fantasy novels that are made with a more western style (eg: Age of Adepts).
