i dont have many comment on this, well its always either bad writing or just the lazy author you decide it
first rule, the worst possible condition ever possible when the mc was born
second rule, theres always sky beyond the sky and mc is just a frog at the bottom of the well dreaming to reach the highest sky
third rule, 10.1/10 luck stat. this is the shitty one. mc find inheritances lying around, 'somehow' strong people help you when mc in a pinch, etc etc
fourth rule, Auction
every generic cultivation novel out there is just a copy paste of one work to another with new name and new settings, you cant deny this
of course theres some good one like ccg but its just that rare
