[Knowledge] Seawater Inflow Device

Summary Seawater is coming in through
an ancient device made of ancient stones.
The salinity of the water is so high
that is can be felt from afar.

Summary You can truly get a sense for the Ancient technology
by looking at their Seawater Inflow Device and Ancient Weapons.
How did they manage to build
this large structure with such a vast open space?

Summary (You discovered Syca's hidden records.)

Master brought seawater to this place.
I don't know how he did it, but the water is different
to that which flows in Vaha's, Yolu's, and Orze's biomes.
This probably means that I'm special to Master.
Perhaps my endless thirst will go away
if Master continues to look at me as he does right now.
