I was the real daughter who had been miscarried for twenty years. On the first night when I was brought back to the villa by my biological parents, I didn't wait for family affection. I only waited for a "Consent Form for Voluntary Kidney Donation" and the iron door in the basement. My brother was in the advanced stage of uremia, and my uncles and aunts sat around and planned to drain my kidneys and bone marrow, and then sell me to an old bachelor from a neighboring village in exchange for betrothal gifts to fill the bill. Lin Wan, the fake daughter who had taken over my identity, walked into the basement in the middle of the night and handed over a key and half of the medical records: "My brother's failure is caused by my aunt's long-term feeding of folk remedies. They treat you as a ready-made consumable and me as a backup blood bank. I understand the clinical path. If you pass the legal exam, we can complete the evidence chain of illegal detention and intentional injury." I bit the tip of my tongue to stay awake and took the key. Don't accept your fate and don't donate a kidney. I want to use legal provisions and medical rules as a knife to send these cannibal relatives to prison and swallow up the family assets that they have long transferred.
