ep 36 spoilers ahead

1.Basically,we get Xue Qi's back story. This entire location triggers her because she is from the desert.

2.It seems she came from a poor family and was sold as a slave. Her shifu acquired her, gave her freedom and trained her (hence she loves her most)

3,Other than this glimpse into Xue Qi's past, this episode (I think) isn't very interesting.
