Global depreciation! With billions in assets, I revitalized my entire family

Lin Xiaoyu awakens with a throbbing headache, finding herself back in her childhood home moments after her mother, Li Xiulan, is diagnosed with a serious stomach illness. In her previous life, Lin Xiaoyu had been powerless to save her mother due to financial ruin and family betrayal, eventually marrying a man named Yang Mingyu for a small bride price, only to be poisoned to death by him and his mother. Reborn at this critical juncture, she realizes she has returned to the past, armed with the knowledge of future tragedies and a desperate need to change her family's fate.

The immediate conflict arises when Lin Xiaoyu and her father, Lin Chenghai, beg her grandmother, Sun Guihua, and uncle, Lin Dongyang, for financial help. The grandmother, biased against her daughter-in-law for not bearing a son, and the uncle, who has been embezzling rent from the family's orchard for ten years, cruelly refuse to lend any money. They mock the family's poverty and dismiss their pleas. Lin Xiaoyu, remembering the abuse she suffered in her past life, including being pushed by her cousin until she hit her head, decides to fight back. She discovers that in this reborn timeline, the value of money has depreciated by a factor of ten thousand, meaning her bank account, which held millions in her previous life, now contains over eighty billion in this new currency, granting her immense wealth.

Using her new financial power and knowledge of her uncle's secrets, Lin Xiaoyu confronts her relatives. She reveals that her eldest cousin is involved in illegal activities, including drug use, which shocks the family and gives her leverage. She forces the sale of the orchard, which her uncle had wrongfully occupied, to recover the ten years of unpaid rent. With the money secured, she takes her mother to a top hospital in Linzhou City. However, securing an appointment with the renowned specialist Dr. Chen proves difficult due to high demand. She encounters a scalper who offers her a slot for a small fee, which she accepts to ensure her mother receives timely treatment.

While waiting for the appointment, Lin Xiaoyu indulges in shopping, purchasing multiple high-end electronics and a luxury Porsche Panamera, treating herself and her family to the comforts she was denied in her past life. At the car dealership, she faces harassment from a salesperson and a wealthy but fraudulent customer, Mrs. Zhou, who tries to claim the car she had already purchased. Lin Xiaoyu calmly handles the situation, exposing Mrs. Zhou's deceit and securing her vehicle. Her confidence and wealth draw attention, including from a high-ranking director at the Apple store who fires a rude salesperson after Lin Xiaoyu reports her for harassment.

Back at her parents' home, Lin Xiaoyu faces further intrusion from her grandmother and aunt, who arrive uninvited and demand food and money, claiming the family is hiding wealth. Lin Xiaoyu firmly rebuffs their greed, exposing their hypocrisy and refusing to let them exploit her parents. The confrontation escalates when her mother, stressed by the noise and her illness, collapses. Lin Xiaoyu, realizing the danger her family faces from these parasitic relatives, resolves to protect her mother and sisters from the tragedies that befell them in her previous life. She prepares to take her mother for treatment, determined to use her wealth and foresight to rewrite their destiny and punish those who wronged them.
