Xu Haode saw his expression and approached, whispering, "Princely Heir, have you found anything?"
Chu Zhiyuan nodded slowly.
He floated up, pressed against the smooth indented stone wall, and gently placed his hand on the wall.
Xu Haode looked over, and his eyes instantly sharpened.
He saw on the smooth stone wall, a small transparent stone, a diamond-shaped small stone.
Only the size of a thumbnail.
Dull and lackluster.
If not for concentrating, it was easy to overlook.
Chu Zhiyuan reached out and gently pinched the small stone embedded in the rock.
His left foot tapped on the stone wall, keeping his body suspended in its original place.
His right hand lifted up, holding it in the air, eyes fixed on the small stone in the air.
A bright moon hung in the night sky.
The moonlight, like water, fell on the small stone.
The small stone seemed to merge with the moonlight and disappeared before his eyes.
