One of the reasons, why Xie'Jing captured Fei: Xie'Jing is a beautiful lady, but she hate couples (Fei and Fang). That's it, why she captured him. And i think, everyone is scared of her, because her lower body is monsterlike and she is a demon...

But if Fei is not save, Xie'Jing will claim him as her own... And then, she drains his life energy bit by bit...



That's my guess, why Xie'Jing have captured Fei ^-^
