Qin Lan's ability to become a mid-tier Great Grandmaster was actually due to her practice of a unique cultivation technique. Despite her youthful appearance, resembling a girl of just sixteen or seventeen, the reality was that Qin Lan, having gone through nine rounds of abandoning and rebuilding her cultivation, had already been cultivating for dozens, nearly a hundred years. In terms of age, Qin Lan was actually the oldest of the three.
Moreover, the greatest effect of the Nine Revolutions Divine Technique was to abandon one's power nine times, breaking through from an A-rank martial artist to a Great Grandmaster in one fell swoop. As for achieving levels beyond Great Grandmaster, the Nine Revolutions Divine Technique offered little assistance; that is to say, a mid-tier Great Grandmaster was almost the limit for Qin Lan. Any further breakthrough would be exceptionally difficult.
