Ye Sha protects Jun Wu Xie ever since the beginning of the novel and through his interactions realizes that although not powerful her mind and skills in medicine and poison are greater than any he's ever seen.

He greatly respects Jun Wu Yao, just like every other Dark Regime subordinate, although half is because Jun Wu Yao can bestow powers beyond compare in return for absolute loyalty.

He is very friendly and kind, while being cruel towards enemies, and his only known friends are Ye Mei and Ye Gu who are part of legion protecting the Dark Emperor (Jun Wu Yao).
