Bah, and here I was already thinking the miracle pill will restore her ability to cultivate. Only for it to be proven 100% it won't in this chapter. Once again I feel like this isn't worth reading if Yeon won't gain any power of her own and must rely on others till the end of the series.
Also, the "villainess" tag seems to be misplaced with this series. Nothing indicates she ever was a villainess. She was a bullied person even in the original in-series novel. The villainesses were obviously elsewhere. In fact we saw one of them very prominently.
