The "extinction tactic" wasn't a name Shibeng came up with himself.
It came from an ancestor of the common Mineral Race.
He discovered that not long after defeating the enemies inside a hollow, new ones would be born.
Endlessly.
However, if the mineral vein within an entire stone pillar was completely destroyed, that pillar would become completely safe, and enemies would no longer appear out of thin air.
This tactic slowly began to spread.
However, the rare Mineral Race quickly learned this trick as well, and both factions began clearing out mineral veins as a post-battle tactic.
As a result, both groups saw a sharp decline in newborns, and the Thorn Stone Forest became even more desolate.
The rare Mineral Race began to hide, moving through the labyrinthine network of interconnected caves. They formed small squads to ambush mineral veins and lone members of the common Mineral Race, making them impossible to guard against.
