interesting but....

I think that the better is to see the original 50-episodes drama, the storyline is better explained and the story is complete. These 20-episodes short drama is nice but many important details are missing, also there is no new scenes or content in it.
So, if you have seen the original long drama, there is no necessity at all to see this one, if you haven't and don't want to see a 50 episodes long drama, you can watch this redux but I suggest you to see the 50-episodes drama.

Anyway, the story, casting, and male carachters are awsome.

visually very interesting

the story is quite interesting, and casting are good, but I don't understand... this should be the prequel to Blood of Youth. In blood of youth they say Wang Ren Sun [Demon sect] was the best friend of Ye Dingzhi, but then he killed him. Why? If you see Dashing Youth you can clearly see that his best friend was Baili Dongjun, and he didn't kill Ye Dingzhi. So who is Wang Ren Sun? Can anyone help me clarify this matter? Which part has Wang Ren Sun here in Dashing Youth?
