The spiritual measurement stele divides cultivator talent into nine grades, and maintainer Gu Yunzheng accidentally discovers that this standard system misses special spiritual energy structures. Relying neither on divine powers nor cheats, through repeated experiments and public re-tests, he uncovers the secrets of tool blind spots and pulse-fixing feedback. When the anti-tide catastrophe strikes, a group of people misjudged by the old system step forward. Ultimately, the nine-grade exclusive qualification is abolished, and a spiritual energy spectrum that only describes structures without ranking highs and lows is established.
