Her actions make sense to me. Not moral at all, but makes sense.
Well, sure she was playing hard to get with the young master guy, but she was probably just trying to up her own value with him. Don't want to be a passing fling once he gets bored of her!
My thoughts were that she was trying to sublty woo/flirt (i.e. catfish) the young master guy.
She's been setting it up for a while.
Suddenly, a guy explodes in a meteor "saving her" ruining wat she build up so far.
Being the oppurtunist she is, she decides to ride the new gravy train of her white knight, i mean cultivator, in shining rags.
For her goal of rising up in the world, she was willing to offer herself to the ultra powerful MC.
Turns out said really stronk cultivator is a nobody.
She, for hopefully some nice reason later on in the story, needs to rise up in the world, so decides that she needs to go back to Plan A, the young master, and slashes the MC.
She is officially now back to Plan A, and shall make good use of the young master until she uses up his usefulness (or the other way around, but i feel like the guy is gonna get played like a fiddle).
