The defensive line at the Imperial Border was deliberately sabotaged, creating an opening through which the pollutants sneaked into the territory.
If it was just such a breach, the pollutants would not be able to enter the border en masse in a short period of time.
Xue Yinzhou secretly discovered a lure device for the pollutants.
This device, within just a few days, had attracted numerous pollutant mutant species to invade the border, becoming the main culprit behind the turmoil among the populace.
Xue Yinzhou held the rhombus-shaped device in his hand and squinted his snake eyes, the silver-purple vertical pupils radiating a chilling aura.
Who did this?
A hostile neighboring country, the rebel army, or domestic traitors could all be the masterminds behind this incident.
But this device is peculiar, never heard of it, even unavailable in the black market; it's unlikely something an ordinary person could produce.
