Magma flowed in the holes, indicating the presence of empty spots in the areas under them. Its quantity in the sea didn't diminish though, confirming the existence of a source somewhere in the ocean.
Noah felt intrigued as he analyzed the holes. The metallic layer wasn't the end of his journey anymore. There was something else hidden in the depths of those Mortal Lands.
Noah didn't know what to expect. The geology of his previous world didn't have the "Breath" in its system. That layout was already strange if he tried to apply the common sense of his past life.
Still, that only made him more curious. The metallic layer was already a useful discovery. It appeared as a material suitable for defensive items, and its durability surpassed anything on the surface.
Moreover, there was tons of it. Mining it would be troublesome due to the dangerous environment, but it was something worth considering.
