The water cup was wondrous. It could nurture Water Drop Gems on its own.
The gems were even more wondrous:
Swallowing one could bring about a Rebirth and Bone Transformation.
A single Rebirth and Bone Transformation could not only preserve one's youthful appearance, but also cleanse all severe injuries.
