Nangong Zi Feng

Caused the Downfall of the Xi Family because she was jealous of the fact that Ye Wu Chen only had eyes for Mu Ru Yue and refused take her in as a concubine.

She used outside forces to set up and attack the Xi Family and when Mu Ru Yue and Ye Wu Chen countered and faced Heaven's Calamity she cut off all Zi Qian Jing's limbs and threw him in front them causing to lose focus and die.
