In a year of severe drought, Lin Qiuyue revives a shriveled lotus seed with half a spoonful of rice-rinsing water. Its stem shoots into the sky, where a white lotus blooms above the clouds. A little immortal named Mu Ling gifts her a magical gourd that produces three portions of water each day. Lin Qiuyue first uses it to save her neighbors and refuses to sell it to the powerful and wealthy Qian Shichang. When Qian Shichang steals the gourd and greedily uses it for a fourth time, the black water comes to collect its debt, leaving him bankrupt. In the end, Lin Qiuyue leads everyone in digging their own irrigation channels, restoring clear spring water to thousands of homes.
