During a famine, six-year-old girl Milly accidentally opens a two-way portal connecting to a modern Northeast China market. At that time, her mother was seriously ill, her four older brothers were still young, and the whole family was on the verge of not surviving the famine. Milly used wild mountain goods and wild vegetables that were common in the mountains and no one picked, sent them to the modern world in exchange for food, medicine and farm tools. With the help of kind stall owners in the modern world, the family gradually got on their feet. The siblings improved farming methods and resolved crises using knowledge learned from the modern world, eventually not only leading the whole village through the famine, but also repaying the kindness of those who helped them, writing a warm cross-time story.
