Yan Hai frowned as she looked at that puppet. Cultivators have categorized Elder Bark as the worst Paragon (Tier 12) material. It cannot be used to make artifacts, pills, or arrays because its characteristics are stubborn and cannot fuse with substances of the same tier as itself. People have tried only using Elder Bark to make their weapons, but besides the fact it's hard to destroy, nothing is interesting about it.
Due to its nature, elder bark has a few uses and is sought after by a small group of the cultivation world. Its primary use is to create [Indestructible Empyrean Puppets]. An Empyrean cannot destroy a puppet created with elder bark, as the minimum requirement to break it is a Paragon Tier attack.
