There was extremely rich pure Yang energy in the Golden Crow species's precious blood.
It was better than any healing medicine by many times. Typical healing medicines, even very high-grade ones, were limited when used by Purple Blood realm warriors. As Purple Blood realm warriors could only absorb a tiny amount, and even after absorbing it, the medicinal essence would take a while to be digested. After all, the medicinal properties of these healing medicines were different to the warrior's energy.
However, since this was the precious blood of the Golden Crow species. The situation was completely different.
As Yi Yun had absorbed the Golden Crow species's beast mark and had condensed a Golden Crow Aspect Totem, the essence and pure Yang energy in the precious blood was highly compatible with Yi Yun considering that they came from the same source. Hence, it was very easy for him to absorb it.
