There is also the panel, the first spatial grid was triggered by 5,000 taels of silver, the second spatial grid was 5,000 low-grade Primordial stones.
So, will the third change of the panel appear after 5,000 low-grade Primordial Crystals?
However, such a quantity of low-grade Primordial Crystals wouldn't generally be consumed by ordinary shops; it would take a considerable amount of time to exchange them.
For outsiders, Chen Fei's bulk exchange of low-grade Primordial Crystals seemed somewhat odd.
After all, at the stage of the Sun Moon Realm, there's no use for Primordial Crystals. If one were so extravagant as to use low-grade Primordial Crystals for cultivating, the rule particles contained within the Primordial Crystals wouldn't be absorbed by someone at the Sun Moon Realm anyway.
At the pinnacle of the Sun Moon Realm, one could exchange some and try to comprehend a bit of the rules from the low-grade Primordial Crystals, but no one would exchange tens of thousands of them.
