This is HORRIBLE!! Worse than isekai wishfulfilment!
Main plot: Money buys you everything.
Other people with money offend MC?
No worries, enough money also gets you connection to tough people.
Assault and violence for basically no reason?
No problem when you're rich and get 'respect' for your money.
Does anybody know how he became so wealthy? Does anybody bother to check?
Nope.
Also, at some point, the 'system' gives MC powerups???
What the hell for?
Also, at some point in the later chapters, first he rips a car door clean off it's hinges with little effort, but then next, he kicks a woman and is surprised she flew away?!?!
I'm surprised she didn't explode in a gory mist of meat and blood!! WTF is wrong with you!?!
....
So anyway, this is absolute trash, DO NOT READ, unless you are (also) morbidly curious at how low this will go.
