Shuert's voice carried a hint of helplessness as he responded, "Before this, when the Shadow Market opened, we could still exchange some with the Dwarf Elves, the Wood Fairies, and other invited individual strongmen, but now, our reserves have long been exhausted."
"I see, the Human World has a wide distribution of mineral resources, with many places producing Magic Crystals."
Leo Ray raised an eyebrow slightly and responded, "It's just that the Magic Crystals from the Human World are of limited quality, not as pure as those from the Outer Region, so please bear with us."
As Leo Ray said, the Human World indeed does not lack Magic Crystals, and large Absolute Defense Barriers for city-scale constructions, Magic Restrictions, and other advanced Magic Arrays indeed require a large quantity of Magic Crystals with various functions to become like Miracle Buildings, autonomously absorbing external Energy Particles for power.
