So I kinda remember a vague novel where the MC 'maybe' reincarnated as a sole heir of a filthy rich parent in some city. The previous owner of the body should be an idiot, and somehow the MC got a system that gives mission, (and possibly rewards?) that requires him to spend a huge amount of money on some interval basis. One of the scene I remember was he was trying to buy a land complex where there is a karaoke casino hotel etc, he was coaxed by the owner to buy it, and it was some other rich family young master that owns it, apparently the place was not making much profit and decide to scam the idiot rich young master (MC) to buy it. The MC tells the parents that he wanted to invest in land, and instead of angry both of the parents are happy, turns out they have some business idea that face a blockade because they unable to buy the plot of land that the MC bought, and now that the MC bought it, the plan is on the move. Also when the MC bought the land, he also hires some woman that works in the karaoke to be his assistant (forgot the reason) and some hoodlum to be his lackey, but turns out the woman was actually smart in economic thingy. MC took her home, where she meets MC's mom (this part might be me mixing up another story I remember). And thats all I can remember. Anyone got any idea as to which novel is it? It might be from qidian's I remember. Thank you.
Now I understand why I stopped reading it and forgeting the title, the novel is too cringy and I can't stand it.
