Bathed in moonlight, the earth was a stark contrast of black and white.
The fine grains of sand reflected the moonlight, and the surface of the desert faintly gleamed white with a solitary black spot conspicuously appearing upon this silver carpet.
The enormous camels bent their long necks to drink, their heads lowered to the ink-black water that rippled with layers of dark and glossy waves.
Bi Fang crouched on one knee, dipped his hand in the water, brought it to his nose for a sniff, flicked his fingers to shake off the droplets, then rubbed them dry on the sand.
"No strange smell, it should be a normal water source."
Today was not a full moon, and visibility was limited, so Bi Fang could not determine the water's purity by sight alone and had to make a rough judgment using his sense of smell.
