The Primordial Chaos Blood Pearl contained an immense amount of vitality and blood energy, but its greatest use was for body refinement.
Gu Yi's fourth, fifth, and sixth Life Severings had been Life Severings of "Qi," while his seventh had been a Life Severing of "Spirit."
This inevitably resulted in some waste of the Primordial Chaos Blood Pearl's energy.
Origin Liquid was different. It was pure Heaven and Earth Origin Qi, suitable for nourishing the soul, improving cultivation, or cultivating divine power.
Of course, Gu Yi required an enormous amount of Origin Liquid.
Based on the energy consumed by his previous Life Severings, Gu Yi estimated the requirements for his eighth Life Severing.
If he relied solely on Origin Liquid, he would need at least ten thousand jin to complete it smoothly and achieve the best results.
As for the ninth Life Severing, he might need tens of thousands of jin of Origin Liquid!
Yet obtaining so much Origin Liquid was no easy matter.
Some Primordial Spirit Daoists without backing might not possess that much Origin Liquid even after adding up their entire fortunes.
After all, Blood God Child Gu Huang had only been able to obtain one hundred jin of Origin Liquid in ten years at Black-White College.

Even if Gu Yi improved his alchemy and could refine Heaven Rank spirit pills, each pill would only sell for several hundred jin of Origin Liquid.
To gather tens of thousands of jin of Origin Liquid, he would need to refine at least one or two
