Deep in the mountains, kind-hearted Granny Liu comes to the rescue of a mother Baize and her child when they find themselves in danger. To repay her kindness, the little Baize gives her a White Baize spirit stone and instructs her to bury it in her courtyard on a moonlit night. The spirit stone bursts with life, growing into an auspicious spirit tree and bringing forth sweet, clear spring water, providing the village with a precious source of water. Just then, a drought strikes the countryside, making drinking water especially precious. Granny Liu and the little Baize work together to explore the hidden underground waterways. When the spirit tree finally bears seven spirit fruits filled with hope, they harness the power of their seeds to locate seven underground springs one after another. The flowing fresh water nourishes the countryside and helps the entire village safely survive the dry season.
