Spiritual Root (灵根)

Spiritual root is the innate aptitude of cultivation — a biological lottery that decides whether a person can absorb spiritual energy and how fast. It has three measurable dimensions: existence (root or no root), elemental affinity (metal, fire, wood, water, earth, or rare types such as lightning, ice, wind, light, dark, void), and grade (purity and speed of absorption).

The three mistakes overseas viewers are most likely to make: reading the result as a moral judgement ("the stone did not light up, so he is a bad person"); reading "waste root" as zero potential (it is extremely low but not zero efficiency); and ignoring that the test is public — not a private act of self-discovery but a declaration made in front of elders, peers and rivals.

The visual cue that actually matters: how many distinct colours light up, not how bright. One colour = top-tier talent. Four or five = struggle for life. The "less is better" rule trips up new viewers constantly, because it cuts against the normal visual-language convention that more colour = more power. The narrative function of the test is not to show how strong the protagonist is, but to manufacture social stakes before the first fight: who enters which sect, who gets cultivation resources, who is left where they stand.

Evidence level: A (terminology and logic verifiable) + B (first-person confusion texts from overseas viewers are thin). Related entries: cultivation, qi deviation.
