Geode Caverns, a total of thirteen layers, the further down, the more concentrated the fire attribute spiritual energy becomes.
It's said that, as you go deeper, it's not just fire attribute spiritual energy anymore, there's something deeper.
These thirteen layers are not naturally formed; they were excavated by the Solarian Royal Family in the past, costing a lot of manpower.
But despite using all their efforts, they could only excavate thirteen layers; going further down is simply impossible.
Because no one can go down; it's said that the last two layers were excavated by an unparalleled Martial King of the ancient Solarian Empire, and others couldn't even manage to descend.
Marshall Morgan heard all this from Flynn Moore.
What's below the thirteenth layer? Countless people in the Solarian Empire ponder this question, but no one knows the answer.
