During a year of famine, a young girl named Xiaoman unexpectedly becomes bound to a mysterious system that allows her to collect wild treasures from the mountains in exchange for magical supplies. Her older brother, a medical student, sees through the secret, and the Chen family uses this opportunity to improve their lives and weather the difficult times together. As the famine worsens, Xiaoman obtains precious potato seeds and sweet mountain spring water, becoming the village's lucky star. When greedy villains attack and criminals seize the opportunity to search the village, the entire community unites to defend their homes. Xiaoman also helps local officials spread the cultivation of potato crops, bringing blessings to countless people. Once the turmoil subsides, the system completes its ecological encyclopedia and temporarily bids farewell, only to return three years later as a permanent companion and a delightful surprise. Peach blossoms fill the sky, and peace and happiness endure year after year.
