Lian Xianxian, in a moment of urgency, resorted to all sorts of means to separate Lian Qianqian and that mortal. However, not only did her various tactics fail, but they also strengthened the bond between Lian Qianqian and the mortal.
Lian Qianqian refused to leave her husband. In desperation, Lian Xianxian began to stop at nothing, and even went as far as threatening Lian Qianqian with the lives of the mortal's family to coerce her into returning to the rightful path of cultivation. As a result, Lian Qianqian, in a fit of anger, destroyed her own Immortal Root and became a mortal!
One could say that Lian Xianxian was a standard villainous female supporting character early on, one that readers loved to hate. But in the end, her character underwent a reversal; it turned out there was a reason why Lian Qianqian's parents didn't want the most likely one to attain immortality, Lian Qianqian, to fall in love with a mortal.
