fountain that never dries up

Exploration Stage: Wonderful Cat Cafe
From: Madame Miyuki
Description: I have been feeding and watering the cats in the twilight. Because of the anomaly, these cats need fresh water from a mountain spring. Could you please find a spring so that the cats in the twilight can drink fresh water at any time?
Completed: Thank you for the fountain stone. It was created by a mountain goddess for her beloved storyteller. Centuries ago, the goddess took her beloved storyteller to heaven, leaving only the stone in this world. From now on, it will be useful for the cat in the twilight.
