As Anvis listened to the Old Explorer Baige Sen's account, his gaze gradually changed.
If such a large Gemstone Mine truly existed on the island, then the nature of the matter had changed once again.
Demonized Material Science had specifically mentioned that at the center of large and higher-grade magic mineral veins, the essence of the entire vein often condensed, forming a higher-grade Mine Core.
For example, the Super Magic Crystals produced at the center of large magic crystal mines, or the Green Glow Crystals produced at the center of Green Trace Iron Mines.
The quality of a Mine Core was inevitably one rank higher than that of the mineral vein serving as its foundation.
If the underlying vein produced mid-tier minerals, then the Mine Core would at least reach the level of high-tier materials.
As a high-tier Magic Gem, if there truly was a piece of raw Emis Heart as large as an entire cave wall, then its core might very well condense a ninth-rank Gem Crystal Heart! A ninth-rank material—
That was a treasure worthy of the continent's top powers' attention, and enough to make Anvis reassess the value of the island's gem mine.
The greatest difference between ninth-rank materials and materials below the ninth rank lay in the portion of high-level power they contained, as well as their material structure, which could bear ninth-rank Rule Power.

Meanwhile, unaware of Anvis's thoughts, the Old Explorer continued his account.
"Those Crystal Spirits aren't invincible. In fact, as long as you prepare in advance, Elemental Spirits that act on instinct are quite easy to counter, even if they're
