The heroine, Lin Wanxing, is a 26-year-old office worker earning 5,000 yuan a month, with 32,861.5 yuan in her bank account, saved from three years of wages and year-end bonuses. She wakes up to find that the world's currency system has changed overnight: the value of all goods, assets, and salaries has dropped by a factor of ten thousand. Ten thousand yuan becomes one yuan, and a million-yuan luxury car becomes worth one hundred yuan. Only the balance in her bank account is “immune to devaluation,” turning 32,000 yuan into 320 million overnight, with actual purchasing power equivalent to 3.2 trillion yuan. As the world's only “holder of original assets,” she embarks on a shopping spree that takes her from a 5,000-yuan monthly salary to becoming the world's richest person with trillions to her name.
