This nine-layer bone altar consumed a large batch of fifth-tier bones just for the materials, not to mention that it also incorporated sixth-tier bones.

Additionally, Zi Liyuan and Mo Yi together inscribed runes to conceal the aura on the exterior of the altar.
It can be said that once this thing is activated, all waves and auras of the Power of Death are hidden.
