Let's keep it short. Let's start with the actors.
Xiao Zhan and Wang Yibo as the main leads are too good and deserve the praises. The rest of the actors including the supporting and guests roles are also good. The plot is pretty surprising for me. Some of the people you expect to know nothing and act so innocent are actually the bad guys and will stab you in the back for power. I haven't read the novel but they all say that it was suppose to be a BL but what can we expect from Chinese dramas is that they censor all the BL scenes like what it should be in the novel. The music is also good the theme song is actually my fav song out of all the historical/fantasy dramas I have watched. I wouldn't recommend watching if this is your first time watching a historical/fantasy drama maybe watch something else like simples dramas I'm gonna recommend one that Xiao Zhan was on it's the Oh my Emperor! and its second season. Then maybe you can watch The Untamed. But if you want to be disappointed read the novel first so you know how different it is from the drama. Enjoy!
