I'm currently into novels in a modern setting where the MC focuses on making money. Don't mention those virtual games (I've had enough of them). List of novels I've read Extraordinary Genius Epiphanies of Rebirth A Valiant Life
Money making plays a big part: https://www.novelupdates.com/series/the-youngest-son-of-sunyang/ Edit What about entertainment based novel? Modern and money making... some arcs in Side Character Transmigrations ( or was it another female MC QT novel? She is very much into money in modern setting) also a rather... peculiar novel, Monster Factory, it is not really geared towards Just Money, but becoming rich from poor is a large part of it and the setting is modern plus...
This one is bl (if you don't mind), the story is really realistic and the romance is not much, it's a HE novel tho~ https://www.novelupdates.com/series/investment-life/
Issac I guess fits this since he’s trying to keep away from any financial troubles. Semi-modern day, since it’s fantasy pre Industrial Age era
I Shall Seal the Heavens not modern but funny as hell! Also awesome book overall. edit: The Legendary Moonlight Sculptor : which you don't like but I've heard good things!!
If you can read untranslated stories, 穿成炮灰白月光 [穿书] Transmigrated into the Cannon Fodder White Moonlight [Quick Transmigration] is one. MC becomes a CEO and expands her business in the entertainment world etc.
