Five hundred years ago, Gu Yunniang performed great deeds in flood control and saved people, earning an extension of her lifespan bestowed by Heaven, and stayed in Willow Creek Village to protect her neighbors. Five hundred years later, on the day of her longevity banquet, King Yama personally visited to uncover her secret. Just as a mountain flood was about to strike, the village granary was privately occupied and the flood-discharge outlets were sealed. Gu Yunniang exhausted her remaining merit, guiding the villagers to save themselves and fight the flood. When the catastrophe subsided, she laid down her obsessions having settled her mortal ties, calmly accepted the guidance of Heaven, and Willow Creek Village also learned not to rely on a single person, with everyone uniting to protect their home.
