"Based on the records, this was a freshwater lake filled with plenty of marine creatures. And, it was replenished by the numerous underground rivers at the place, acting as the thumping heart of this region's vitality."

It contains too many metallic minerals that inhibit plant growth."

"Is there no information about this marine creature?"

How did the terrain of this place change so much? What…actually happened here?"
