Xiao Yan never marries her, but she ends up Living with him and his family. The author has been pretty vague about that. And there is not much about her in subsequent works too. Sadly, chinese novel authors seem to love to cast away best girls.
@raydnt I hope so too. You are right about changes, and I am actually surprised by the amount of little details changed. But I still don't understand authors decision to shove her aside, since polygamy is a common thing in the setting anyway. But it seems that it's just the way chinese authors work. Just look at the Martial World.
Shitty scheme, the MC is always training and reach evry step by hardworking while all the girls around him are just breaking thru like its nothing, it's really unbearable to see the MC getting owned by his own lovers after giving them a pill.
