Whether it's [Heavenly Sun Cream Jade] or [Ice Marrow Cold Jade], although they are relatively precious spiritual objects, their availability isn't so rare that they are difficult to obtain.
The true reason these two Nascent Soul Spirit Materials are scarce is that normally, Nascent Soul Stage Cultivators are unwilling to put in the painstaking effort to refine these items that are of no use to them and would hinder their own cultivation.
Zhou Chun's Second Nascent Soul Incarnation can entirely refine [Extreme Yin Ice Marrow Liquid], and Fengyuan Monarch, after becoming proficient, is also capable of refining [Extreme Yang Fire Essence Liquid].
However, they both need to focus on their own cultivation, so they barely spare any time to refine these items.
