神秘洞穴中的发光水晶球

A huge crystal sphere floats in a cavity surrounded by darkness. The crystal glows from within, its light casting intricate patterns on the surface of the sphere. The sphere is at the center of the cavity, with a huge waterfall cascading down below it. The water from the waterfall glistens with the crystal's light and looks like tears of crystal. The walls of the cavity are made of dark, mysterious rock, the surface of which is covered with ancient paintings. The paintings depict strange creatures and gods, all illuminated by crystal light. The entire cavern is filled with mystery and magic, and one feels as if one has wandered into another world --ar 9:16 --v 5.1
