"These bones are too hard, aren't they?"
"They can actually withstand the impact of a Hollow Void Practitioner's magical treasure!"
"Dark red?"
"Could it be because they were stained with Immortal's Blood?"
A group of Hollow Void Practitioners forcefully broke through the undead that surged like waves and then rushed into a rather large cave, disappearing into it.
The undead chased them frantically, but when they entered a certain distance into the cave entrance, they stopped pursuing.
This scene set off a flurry of discussion among the spectators.
"It seems their task is merely to guard the area around this mountain body, and not to let anyone approach."
"They don't care once someone enters the cave; is it because their orders are such, or is there something inside the cave that induces subconscious fear in them?"
"We are so far away, they won't attack us, will they?"
Having seen the might of these undead, everyone started getting apprehensive.
