Every night, Granny Su gets up to feed warm goat milk to the injured Golden Dragon hidden in her cellar. For twenty full days, the milky fragrance nourishes him, and his dim dragon scales gradually glow with a faint light. On a perilous night when a mountain flood sweeps through the village, the Golden Dragon remembers her kindness and spits out a Water-Calming Pearl. Bowl after bowl of goat milk and twenty days and nights of steadfast persistence allow Granny Su to use her modest kindness to protect all the villagers, trading twenty bowls of goat milk for the lives of an entire village.
