"The Blood-Refined Yin Corpse Formation?" Lin He looked utterly bewildered, but Zhou Yuan explained in a grave voice,
"This is a corpse-refining formation. It can turn the corpses within its boundaries into refined corpses under someone's control. These refined corpses cannot die or be destroyed. Anyone trapped inside will slowly have their magical power drained until it runs dry, then be killed by the corpses."
"They can't die or be destroyed?" Startled, Lin He could not help asking, "A formation that defies the heavens like that actually exists?"
