In a famine year we split the family I emptied the deep mountains making the shameless relatives drool with envy

Liú Xiǎomǎn, a modern agricultural scientist, awakens in the body of a fifteen-year-old girl in ancient times, dying of a severe lung infection beside a mass grave. She has been cast out by her cruel grandmother, Elder Tián, and her greedy relatives, who claim she is a jinx. Her only companions are her timid mother, Lǐ Xiùxiù, and her simple-minded ten-year-old brother, Liú Cōngmíng. As she faces imminent death from lack of medicine and food, a system binds to her, granting her the ability to scan plants for value, recycle them for points, and exchange points for items like antibiotics and food. Using this advantage, she survives her fever and begins to secure resources for her family.

Liú Xiǎomǎn discovers that common weeds have value in the system, allowing her to generate points quickly. She exchanges points for antibiotics and rice porridge, saving her life and feeding her family. When her aunt, Wáng Jīnhuā, comes to steal their food, Liú Xiǎomǎn uses her sharp wit and knowledge of the law to repel her, citing the separation document that legally severed their ties to the main family. This confrontation marks the first time the weak family stands up for themselves, though it also deepens the enmity of the Liú family elders.

Realizing the hut by the grave is unsafe, Liú Xiǎomǎn ventures into the nearby mountains to find valuable herbs. She discovers a rare variant of Hemostatic Vine, a highly prized medicinal plant, and sells it to a local apothecary, Huíchūntáng, for a significant sum of silver. She uses the money to buy food, supplies, and a VIP membership that allows her to operate openly. The profit attracts the attention of her cousin, Liú Dàbǎo, who reports her success to Elder Tián, leading to a second confrontation where the family attempts to seize her earnings. Liú Xiǎomǎn outmaneuvers them publicly, using a system item to cause Elder Tián to fall into dog feces, humiliating her and securing the village chief's support for the family's independence.

With the immediate threat of her relatives neutralized for now, Liú Xiǎomǎn decides they must move deeper into the mountains to a hidden location. She explores the back mountains and discovers a massive cave concealed behind a waterfall. Inside, she finds a rare material called Super Clay, which is valuable for construction and can be recycled for points. She purchases a safehouse renovation blueprint from the system and begins a secret operation to transport building materials, such as nails, cloth, and salt, from the town to the cave under the cover of darkness.

Liú Xiǎomǎn gradually involves her mother and brother in the plan, teaching them survival skills and using system-enhanced tonics to improve their physical abilities. The family works together to move supplies to their new hidden home, establishing a secure base away from the dangers of the village and the greed of their relatives. As they prepare to build their new life in the cave, Liú Xiǎomǎn continues to explore the mountains, discovering more resources and opportunities to grow her wealth and power, setting the stage for a future where she can protect her family and thrive in this new world.
