Orphaned since childhood, little Yaya treasures the sachet left by her mother, which unexpectedly connects two space-times. At that time, Lotus Village was plagued by natural disasters, and the villagers lived in hardship. After learning the secret of the sachet, the elders in the village discussed ways to exchange supplies, sending wild produce to the modern world in exchange for grain, farm tools, and medicine to relieve the whole village. Everyone worked together to keep this opportunity secret, farmed diligently, and joined hands to resist external invasions. Relying on two-way material exchange and mutual help, the originally impoverished village gradually became stable and prosperous, turning into a wonderful home where everyone lives and works in peace and contentment.
