Top security expert Shen Qinglan suffers a car accident and falls off a cliff. Transmigrating across time, she becomes a peasant girl in Linshui Village of the Daliang Dynasty, specifically the third daughter of the Shen family whom everyone previously regarded as foolish and dull. The original owner was struck by a rampaging mad ox and heavily injured into a coma, with everyone thinking she could hardly survive the ordeal.

Shedding her foolish facade, Shen Qinglan relies on her extraordinary insight and adaptability to find produce in the mountains and run businesses, leading her family in striving to improve their lives.
