At first, Ye Yunsheng didn't pay much attention to this so-called 'Ancient Treasure Mirror'.
Although it was indeed somewhat useful, it ultimately was just an ordinary Identification Magic Tool.
The so-called guidance was nothing more than the usual Wind Seeking Technique and Light Seeking Technique, able to display unexplored temporary maps on the mirror surface and find paths in unknown caves.
But quickly, Ye Yunsheng noticed this mirror was not just ordinary.
It could actually locate 'treasure troves'!
In today's Tianyuan Realm, so-called treasure troves are no longer the traditional precious spiritual objects or ancient caves - those are too distant and almost legends.
For the Tianyuan people now, a feng shui earth vein with little demonic qi is considered a treasure trove. Some lively spiritual plants and stones are regarded as treasures.
