Lin Yue returns to thirty years in the past and saves his despairing wife just in time. Accompanied by the spiritually perceptive yellow dog Dahuang, the squirrel Huiqiu, and the big white goose, Lin Yue unexpectedly unlocks a portable space. He gathers wild produce in the mountains and catches fresh river delicacies to earn money to cure his daughter's congenital heart condition. When the village's autumn harvest becomes difficult to sell, Lin Yue takes the initiative to buy mountain produce from his neighbors, builds a dried-fruit processing line, improves storage and packaging techniques, and develops a distinctive dried-fruit brand. He helps the entire village increase its income and plans the cultivation of mountain cash crops. His family lives together in peace and harmony, and the whole village welcomes a stable, prosperous rural life.
