The rate at which immortal stones formed simply could not keep up with the rate at which cultivators absorbed them. Judging by the current situation, even ten thousand low-grade immortal stones might not be enough to exchange for a single mid-grade immortal stone.
The most straightforward comparison was that mid-grade immortal stones were quite beneficial even for True Immortals' cultivation, while a Heavenly Immortal at the peak stage would need hundreds of thousands of low-grade immortal stones for a single cultivation session.
Moreover, they contained many impurities. Many Heavenly Immortal cultivators would not choose to cultivate with low-grade immortal stones.
Thus, the higher the grade, the more enormous the disparity in their exchange value became.
Were seven million low-grade immortal stones a lot? They certainly were, but even seven million low-grade immortal stones might not be enough to exchange for seven hundred mid-grade immortal stones.
As the saying went, rarity bred value—the scarcer it was, the more useful it was, and the more expensive it became. This principle applied everywhere.
"Senior Brother, I just remembered that I happen to have something I don't need. I'll take it out and sell it. I'll go have a look in the back first."
Holding the Sword Talisman, Ye Lin smiled at Jian Nan. This time, he did not want low-grade immortal stones. What he wanted were mid-grade immortal stones.
The disciples of these great factions should have mid-grade immortal stones in their pockets, right?
His Sword Talisman contained the full-power strike of a peak Heavenly Immortal sword cultivator. With this thing, one could practically stride sideways through the Purple Cloud Star System.
Even if these were all prodigies backed by Heavenly Immortal masters, could they guarantee that every one of them possessed a life-saving trump card?
"Alright, I'll wait for you here."
