Devouring Snake was engrossed in picking up the gold sand. It seemed to know that the sand was scattered by the wealth-guarding ghost, and this sense of fulfillment from completing its punishment could only be achieved by itself.
"Gurgle, gurgle." Devouring Snake made a contented sound from its mouth. It glanced at the wealth-guarding ghost and found it extremely pleasing.
Its intelligence was not high. It only knew that it now had food to eat, a place to sleep, and it enjoyed the game of picking up gold sand. The wealth-guarding ghost naturally emitted a scent that it found familiar, and so, it slithered around and coiled lightly around the wealth-guarding ghost's neck.
"Huh?" The wealth-guarding ghost was startled when Devouring Snake climbed onto his neck, but quickly understood.
The Devouring Snake wasn't trying to kill it, but was showing affection.
