Reborn to Break off Relations with Mother! The Scumbag Father and His Whole Family Regret it.

Ning Bu Wan, a Nascent Soul cultivator, dies in a secret realm and is reborn into her five-year-old body in a historical setting. She returns to the moment her mother, Su Shi, is coerced by the Ning family into posing as a distant cousin to hide Ning Bu Wan's true parentage from Princess Ping Le. Ning Bu Wan realizes the Ning family's true intent is to eliminate her and her mother once their political utility expires, a fate that led to the massacre of her maternal village in her previous life. Determined to change her destiny, she manipulates the situation by feigning abuse, convincing her mother to sever ties with the Ning family permanently.

Before leaving the capital, Ning Bu Wan discovers that a spatial artifact from her past life has accompanied her reincarnation. She uses this space to steal spirit stones and treasures from the Ning family's storeroom, setting up a spiritual energy gathering array to begin her cultivation in this new world. She successfully breaks through to the third layer of Qi Refining and learns the Xuan Yu Wood Technique, awakening a phantom vine on her wrist that grants her enhanced combat abilities. She and her mother return to Qinghe Village, where her maternal grandparents have been injured, and the family faces financial hardship and hostility from the Ning clan's local branches.

Back in the village, Ning Bu Wan uses her cultivation skills to protect her family. She rescues her uncle from a tiger attack and later defeats Ning Yuwei, a relative who kidnaps her to force the return of a carriage. She leaves Ning Yuwei for dead in the mountains, presenting his disappearance as an attack by wild beasts while secretly disposing of the body. The village benefits from the game she kills, and the family begins to recover financially. Ning Bu Wan opens a general store with her mother and purchases medicinal ingredients to heal her grandparents' injuries, using her pill-refining skills to create effective treatments.

As the family stabilizes, Ning Bu Wan continues to cultivate, aiming to reach the Golden Core stage to ensure she can protect her loved ones and seek revenge against the Ning family and Princess Ping Le. She maintains her cover as an innocent child while secretly accumulating power and resources. The story follows her strategic maneuvers to secure her family's future, eliminate immediate threats from the Ning clan, and build a foundation for her eventual rise in both the mortal and cultivation worlds.

The narrative highlights Ning Bu Wan's dual life as a child in society and a cultivator in secret. She navigates family dynamics, economic challenges, and local conflicts while preparing for larger confrontations. Her actions demonstrate her growth from a victim of circumstance to a proactive agent of change, using her past life's knowledge and current cultivation to reshape her fate. The story sets the stage for future conflicts with the Ning family and the broader political forces in the capital, as Ning Bu Wan works to uncover the truth behind her mother's past suffering and prevent the tragedies that occurred in her previous life.
