The reason top-grade Spirit Stones are so precious is that, regardless of low-grade, mid-grade, or top-grade Spirit Stones, they are used up once consumed.
Only top-grade Spirit Stones can be reused. After the Spiritual Energy within them is depleted, they turn into transparent stones. Placing them in areas abundant with Spiritual Energy allows the stones to absorb and replenish, transforming them into top-grade Spirit Stones again.
Due to this reusable characteristic, top-grade Spirit Stones are exceedingly rare, and the Blood Sand Stone is equally valuable. It is generally auctioned at top-grade Spirit Stone prices, or even higher when bartered with anything less.
The Blood Sand Stone's tremendous worth attracts countless adventurers to the perilous Blood Mist Desert, willing to risk life and limb for it.
Since they were passing through the Blood Mist Desert, Tan Shuangshuang and the group decided to try their luck and possibly acquire some Blood Sand Stones.
