"Do not worry. During my travels long ago, I accidentally discovered a Spirit Crystal Mine primarily composed of Top-grade Spirit Crystals."
"I have more than enough Top-grade Spirit Crystals on hand. It is low-grade Spirit Crystals that are too few and insufficient for my use."
Su Shi'er offered the explanation lightly.
He could hardly tell her that he possessed the supreme treasure, the Heaven and Earth Furnace, which could continuously refine low-grade Spirit Crystals into Top-grade Spirit Crystals.
A Spirit Crystal Mine was undoubtedly the best explanation.
As soon as he finished speaking, Su Shi'er took out another Storage Pouch. Inside were all the Top-grade Spirit Crystals he had on him.
"Exchange these Top-grade Spirit Crystals as well."
"Any premium exceeding twenty percent during the process may be kept by Hundred Treasures Pavilion."
Su Shi'er continued with his instructions.
When exchanging Top-grade Spirit Crystals for high-grade Spirit Crystals, the premium already exceeded ten percent. Exchanging them for low-grade Spirit Crystals, let alone twenty percent, premiums of thirty or forty percent were entirely possible.
Still, Nangong Yi had returned the Spirit Crystals from their earlier transaction.
Moreover, Hundred Treasures Pavilion would inevitably have to run about to handle the matter.
Naturally, Su Shi'er would not be stingy.

Of course, Su Shi'er's current resources could still be considered quite abundant.
Even though he had consumed considerable resources recently, compared to cultivators of the same realm, he was still among the very best.
If outsiders learned of such a rate of resource acquisition, every one
