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?
