The voice of the wind calling

Exploration Stage: Compartment No.8
From: Bao
Description: The evil spirits that have begun their rampage in the wake of the eclipse will not try to lure them into a trap on their own. Special methods must be used to lure them into the trap. Look for an offering stone. This is also called a "squeaking stone," and its sound should attract the evil spirits.
Completed: I am glad to have found the offering stone. This stone, which came from Lake Taihu, has been sharpened by the flow of groundwater, creating holes inside. That is why this stone "squeaks". The wind passes through them and creates a mysterious sound that is out of this world.
