Before the night had fully faded, Hu Yuan stood in the corridor, watching Cháng Mínghào wrap the Canglang Retrograde Bead Chain around his wrist.
"Senior Brother, can this bead chain really trace a presence from three days ago?" Su Qingyun held a brocade pouch containing a map of the Liu Family's mineral veins she had drawn overnight, the tip of her brush still stained with a bit of cinnabar. "I heard from a Zhao Family elder that the Liu Family's 'Earth Vein Compass' can disrupt the spiritual qi trajectories within a ten-mile radius, rendering ordinary detection techniques completely useless."
Hu Yuan took the map, his fingertip tracing the "Black Wind Valley Branch Line" marked upon it, where Su Qingyun had drawn a tiny skull. "The Retrograde Bead Chain can trace not only spiritual qi, but karma as well. Since the Liu Family disturbed the cinnabar mine, they are bound to leave karmic traces related to the vein. The chain can lead us straight to the source."
