On the eve of my father's surgery, one hundred thousand yuan of life-saving money vanished into thin air, yet the bank manager said it was merely one hundred thousand yuan. I did not make a fuss or quarrel, but queued up every day to withdraw one yuan, printing vouchers and stamping them to leave evidence. On the seventh day, the manager called the police, but the police stood up for me on the spot. They thought I was merely a troublesome customer, not knowing I had spent three years in financial risk control. Voucher by voucher, it gradually unraveled the dark interest network between bank insiders and outsourcing companies. Until the mastermind reached out toward my father's hospital bed, did I understand that what needed to be reclaimed this time was not just one hundred thousand yuan, but a family's life and dignity.
