Liang Yuan looked at a rune bone shaped like a bone arrow in his hand and examined it carefully.
This rune bone had a sharp end, was overall flat, and resembled a sharp backward spike growing from the head of some mutant fish.
It also somewhat resembled the spike on the head of an anglerfish.
The entire thing was white, with intricate runes entwined on it, emitting a faint greenish glow.
These runes were nearly impossible to discern with the naked eye unless perceived through spiritual power.
Liang Yuan activated his Spiritual Ability Assessment skill, and a large amount of analysis data appeared in his mind.
"Item Analysis... Swordfish Bone Spike..."
"Main attribute... Spirit Class... Secondary attribute... Constitution..."
"Skill Category... Causal Skills..."
Liang Yuan immediately smiled, "There really is a causal skill!"
He immediately put away the Swordfish Bone Spike and began comprehending it on the spot.
