Background

Lei Xing is the elder sister of the Lei Family patriarch and the great-aunt of Lei Sai and Lei Jiaojiao. Though her true age is over seventy, she preserves the appearance of a young girl through her cultivation and a youth-preserving technique. 166 191 212

She is the Water-Splitting Sect's Supreme Elder and a senior martial sibling of sect master Fei Wei. Within the sect, disciples such as Hao Ben address her as Martial Uncle. 172 191 209

Lei Xing is married to Fu Yu, a Slayer Commander of the Anshun Prefecture Demon Slayer Bureau. Their daughter, Fu Ya, serves as deputy hall master of that bureau's Internal Affairs Hall. 211 212 215

Appearance

Lei Xing outwardly resembles a small child despite being an elderly sixth-rank martial artist. She commonly wears water-blue clothing. 166 191

• Short stature, standing under 1.5 meters. 191 215
• Round face and twin hair buns. 166 191
• Water-blue dress or gauze skirt. 166 172 191
• Dark, composed eyes that contrast with her childish appearance. 166

Personality

Lei Xing is playful, sharp-tongued, and enjoys teasing Lei Sai and Lei Jiaojiao, whom she treats as much younger relatives despite their discomfort. Her “special training” is notoriously harsh, involving underwater breath-holding, poison resistance exercises, and impact conditioning. 166 168

Beneath this mischievous manner, she is protective of both her sect and family. She arrives at the Cold Pool Blessed Land to shield Water-Splitting Sect disciples, defends Mu Yang when Lu Zongsong speaks dismissively of him, and remains deeply worried over Fu Yu's disappearance. 191 223 211

She respects demonstrated strength rather than fearing it. After witnessing Mu Yang's power against the Mirage Serpent, she considers herself and Fei Wei burdens on his mission to find Fu Yu. 214
