In this sham treasury, Lin Bai saw several old wooden shelves that people hadn't cleaned for many years. On them were some withered, low-grade spiritual herbs and medicines!
Below one of the shelves, a round stone caught Lin Bai's attention.
Casually, Lin Bai walked over and picked up the round stone, examining it in his hands. He noticed the dense cracks on it as if it were about to crumble at any moment.
"What is this?" Lin Bai asked the disciple behind him.
The disciple explained, "This stone has been in the Canghai Yuntai Palace for some years now. It is strange, although this stone is indeed a spiritual tool, its spirituality is quite low, almost negligible."
"Were it not seen as a spiritual tool, I reckon the sect would have discarded it long ago."
"Yet this stone has its peculiarities; it is impervious to knives or axes, and unaffected by water or fire."
The disciple spoke nervously.
