The speed at which Blood Devil Spear was absorbing the Blood Essence was very fast, but even so, Blood Essence from the Blood Pool on top of the altar was not showing any sign of decreasing. It was as if there were an unlimited amount of Blood Essence stored.
Ye Xiao could not even think of for how long the demons have been killing people to store so much Blood Essence in the Blood Pool for the Blood Devil Spear to absorb. What he did know was that it must have been at least thousands of years, and they must have killed hundreds of thousands of people to store so much Blood Essence here.
Ye Xiao had waited for more than three hours after laying down the formation but the Blood Devil Spear was still absorbing the Blood Essence and the Blood Essence was not decreasing at all.
