@JWChibi agreed, good villainess novels are usually about "not being unreasonably evil" even if the MC is cunning and savage, but pretty much all the worlds Su Luxia visits are based on shitty plots and this one was "self-made" by the world itself so I can understand why it's not "well written".
As someone else said, this webtoon pretty much criticizes the absurdity of many stories so that feeling of "no one would like the original plot" is intended
