Staring at the "Signal Whistle" hanging from his chest, Mountainside Li's expression rarely turned serious.
As an essential item for merchants traveling through the wilderness, the "Signal Whistle" was mainly used for early warning.
Within a certain range, it could detect medium-grade and above aberrations. The higher the Quality of the "Signal Whistle," the wider and more precise its detection range.
