No one is born to be a female partner, no one is destined to bear the pain for another person, and use his life to pave the way for another person.
So...
Ye Xiaoxue: Female supporting role! Come and block the knife for this heroine!
Xiao Lingzhen: Who said I am someone else's female partner? I am my own heroine!
This is a straight (silly) drama (white) wind (sweet) story of cultivating immortality in which someone was slapped by a butterfly and never got back on track.
