I know there is a comic book. I don't know if this link is from the comic book or the novel (but it's the same story), but perhaps the comic book took some artistic liberties.

PS:
I always go back to these videos. I love this scene from the drama (A moment but forever).?????

These scenes make me imagine what the scenes of Yuan Zhong, the fox priest, will be like. There will certainly be fights and fights as beautiful as these. Hao Chen (Liu Xue Yi) was an excellent magical warrior. His character, Yuan Zhong will be too, I suppose.??????????
