After severing family ties, your ancestral home was lost? What's that got to do with me?

Song Lianying, a skilled military medic from the modern era, dies during a cross-border rescue mission and transmigrates into the body of a girl with the same name in the Xia Dynasty. The original owner was a once-intelligent young woman who became mentally impaired after being knocked unconscious while trying to stop her wicked grandmother, Jiang Shi, from selling their mother. Her father, Song Dachuan, a former soldier, was crippled after his spine was broken by his own elder brother, Song Si, and his younger brother, Song Cheng’an, a child prodigy, had his right hand crushed, ending his scholarly prospects. The family was stripped of their wealth and forced into poverty. Upon waking, Song Lianying finds her father on the verge of selling her mother’s jade pendant to pay for her medical treatment. She stops him, revealing her restored sanity and sharp intellect, shocking her family and terrifying the grandmother who had orchestrated their ruin.

The central conflict revolves around the Song family’s struggle for survival against the predatory main branch of the clan. Jiang Shi and her son Song Si had previously sold the mother, Li Shi, and seized all family assets. Now, they attempt to steal the last keepsake, the jade pendant, leaving the second branch with nothing. Song Lianying, utilizing her medical knowledge and strategic mind, confronts the grandmother and her cousin Song Shuangshuang. She exposes their cruelty before the village elders, forcing a public severance of family ties. With the help of Village Chief Song Lizheng, Song Dachuan successfully cuts all legal and familial connections to Jiang Shi’s branch, retaining their dilapidated hut and four acres of land. This decisive action marks the first major turning point, freeing the family from the grandmother’s control but leaving them in dire financial straits.

During the confrontation, Song Lianying discovers that the jade pendant contains a mysterious spatial dimension. By accident, her blood activates the artifact, granting her access to a "City Development Space." This space allows her to unlock modern facilities such as hospitals, supermarkets, and farms in exchange for silver. Initially, she finds the costs prohibitive, but she soon discovers she can exchange items from the ancient world for currency within the dimension. She begins by selling weeds and later catches bamboo rats in the mountains, generating a steady income. She uses the space’s "Spirit Water" to heal her father’s paralysis and her brother’s injuries, restoring their health and hope. This supernatural advantage becomes the foundation for her plan to rebuild the family’s fortune.

With her father recovering and her brother’s hand healing, Song Lianying focuses on economic empowerment. She partners with Li Xiumei, the owner of the wealthy Fugui Restaurant, to sell wild winter bamboo shoots at a premium price. This business venture provides the capital needed to unlock more advanced buildings in her spatial dimension, including medical and food processing facilities. Meanwhile, her brother Song Cheng’an, though still facing harassment from his cousin Song Chengjie, begins to regain his confidence under his sister’s protection. Song Lianying’s dual identity as a modern medic and a savvy businesswoman allows her to navigate the feudal society with ease. She treats villagers with her advanced medical knowledge, building a reputation that further secures her family’s social standing. The story follows her systematic dismantling of her enemies’ power while elevating her family from destitution to prosperity, setting the stage for future confrontations with those who wronged them.
