"Origin stones certainly have different tiers, just like spirit stones. Grade-eight mortal origin stones are enough for half of all Nascent Soul cultivators to cultivate to the Great Circle of Nascent Soul, but for me, they are not enough."
The reason was simple: Zhou Chuan's Nascent Soul was his true body, not a sickly Little Red Man. His growth was destined to be much harder than that of ordinary people, and the resources he required were of a much higher grade.
"The origin stones I took are enough for Xiaojin and me to cultivate. The origin stones and the ten-thousand-year medicinal crystals should be enough to raise my cultivation base to the mid stage of tier six. My cultivation base can no longer be categorized simply by Nascent Soul and Deity Transformation. Nascent Soul cultivators stay in the Nascent Soul stage to repair the innate flaws of their Nascent Soul and prepare for cultivating a complete Primordial Spirit. But my Nascent Soul has no innate defects, so there is no such thing as perfection for my Nascent Soul."
