Background / History

Xiao Fen operates as Wu Ling's research-focused clone. While Xiao Hong handles physical training and Xiao Lan focuses on sword techniques, Xiao Fen develops the tools, techniques, medicines, and infrastructure that support Wu Ling's cultivation and long-term plans. Wu Ling considers her “the key among keys” to both his present and future projects 22 42.

Her early work included secretly acquiring Spirit Beast remains and producing a purple spiritual medicine intended to please Bibi Dong. Wu Ling discovered her concealed workroom but chose not to interfere with her privacy 33.

She rapidly expanded her research into cultivation support, creating anti-surveillance and anti-eavesdropping spirit arts from Spirit Beast blood, cultivation-enhancing potions, and a basic cultivation technique that improves refinement speed 35. Her later projects encompass spirit-power automation, formations, magic circles, Spirit Tools, genetic engineering, and cross-world travel 49 145 225.

Personality

Xiao Fen is highly intelligent, industrious, and intensely research-driven. She can be secretive about unfinished work, but consistently directs her inventions toward Wu Ling's goals and safety 33 143.

She shares Wu Ling's thought process closely enough to anticipate his intentions and prepare solutions before he fully explains them. Although she occasionally complains about the workload he gives her, she remains dedicated to completing it 42 67 158.

Her enthusiasm for research can be intimidating to others; Huo Yu'er is unsettled by Xiao Fen's fanatical approach to experimentation 163.
