The CGI and scenery are fantastic and the plot is different from novel and somehow interesting.
The ML Shi Yin is great in both acting and visual.
The relationship between Shi Yin(ML) and Zhu Yan (FL) slowly change from stranger to master and pupil and finally to..lover(not yet but now they have feeling for each other).
Shi Yin's love for Zhu Yan is very delicate and worming (I love that kind of love, non-toxic )
SY spoils his little pupil Zhu Yan like a child at first but now his feeling gradually change but he still spoiling her.
For Zhu Yan, her master is the most handsome, great, powerful man in the world and she would like to stay with him together alone for lifetime (yet she didn't notice her feeling for master)
They sacrifice for each other
Save each other .

The history of the kingdom and royal families is also complicated and interesting.
Bai Xue Lu is the 2nd character I like after Shi Yin because she is determined and she do anything to get what she want.

Worth to watch if you're Xian Huan drama fan.
