Top agent Song Ran accidentally time-travels, and on the refugee road, she is sold by her grandmother for a cheap price of ten cash to the blind scholar Xie Chen. The Xie family has bare walls with wind leaking through the thatched roof, and life is destitute, while they also have to deal with difficult neighbors in the village. Relying on her martial arts skills and exquisite medical skills, Song Ran goes up the mountain to hunt wolves and gather herbs to do business, makes delicious food and builds her career, striving to make money to support her family. Her nominal husband Xie Chen is blind and deep-hearted, harboring cold poison and heavy secrets. At first, he is full of vigilance against Song Ran, but is gradually moved by her vitality and resilience. While fighting villagers and solving the strange poison on her body, Song Ran pulls along her brother-in-law Xie Qi, mutually probing with the cold blind scholar, and carves out a prosperous life of their own in the troubled farming household.
