Black Card List

Three years after his sister disappeared, delivery boy Lin Zhou received an order without an address. The recipient wrote my sister's name, and the only note was: Brother, help me deliver the last order. He got a black card. After each order is delivered, the black card will display the recipient's most hidden piece of evidence. The recipient of the first order was the person who participated in burying my sister three years ago. From that night on, Lin Zhou was involved in a list covering the whole city. Some people knelt down and begged him to delete the evidence, some offered a price to buy his life, and some told him: Your sister is not dead, she is the real owner of the black card.
