Tao Youyou, a modern office worker, overworks herself and suddenly wakes up having been reborn as a four-year-old girl in ancient times during a famine. She awakens a special ability: an unmanned delivery station that automatically restocks its supplies. Every day, the station generates new pickup codes, and whenever an item is collected, it automatically replenishes itself. During a devastating drought and famine, her family is starving and freezing. Tao Youyou takes out rice and fever-reducing medicine, saving her family from running out of food. When she encounters bullies from the Ma family and repeated acts of secret retaliation, she relies on the supplies from her delivery station and joins forces with her family and the village chief to overcome each crisis. Step by step, the Tao family escapes poverty, builds a new blue-brick house, develops a snack business, and establishes itself in Mingshan Village. At last, the whole family enjoys a comfortable life with plenty of food and warm clothing.
