My Unhinged Sister Splashes Hundreds of Billions Just to Keep Her Brother Alive!

【Every penny you spend can extend the life of someone dear to you】 The moment Su Wan opens her eyes, she binds to a tycoon System. Not only does she get cashback on every purchase, but prices have plummeted to practically nothing! “Ding! Today's spending: 1 yuan. Cashback: 1 yuan. Special mission: Spend hundreds of millions to save your younger brother's life!” A villa for 10 yuan? Buy it! A factory for 1,000 yuan? Take it over! From then on, she splashes cash with one hand to face-slap her snobbish relatives, while building schools and saving terminally ill children with the other. When she stands at the top of a charity gala, the wealthy families who once mocked her beg to work with her. Su Wan smiles faintly. “Money was never what I wanted...” “I want every child like my little brother to be able to afford to stay alive.” Then one day, the System's shop refreshes with two outrageously expensive options: 【Immortality Potion】 or 【End Global Poverty】 The whole internet explodes: “That crazy goddess who casually donates elementary schools is actually the real nemesis of the financial elite?” 【The setting is fictional. Do not take it as reality.】 【A brainless wish-fulfillment novel. The author is broke; all portrayals of rich people come from the internet and pure imagination.】 【The female lead is no saint. She's simply been suppressing her feelings, and the darkness within her is no less than anyone else's.】 【But who doesn't have the silly dream of a peaceful world without disease or poverty?】 【The female lead isn't interested in romance, only financial transactions. It's hard to say whether this counts as no-CP.】
