Aur calmly sat cross-legged, his gaze fixed on the crystal in front of him, which was already more than halfway turned to purple. This indicated the substantial amount of mana stored within.
High-grade mana crystal!
And this wasn't the counterfeit one he had obtained, with less mana, even comparable to the middle-grade mana crystal he had acquired through a dubious business deal. This one was authentic, brimming with complete mana.
A satisfied expression crossed Aur's face as he observed the crystal.
The high-grade mana crystal he had exchanged for middle-grade ones was filled with pure and dense mana. Not only was its quantity higher than a hundred middle-grade mana crystals, but its quality was also superior.
It's important to note that there was always a high demand for high-grade mana crystals, but the supply was scarce. Even Noah, the village leader, only received one high-grade mana crystal per month from the allocation of resources.
