Mingfei is a debt collector who can use magic. A family owed Mingfei a large sum of money, but when the due date came, they did not intend to pay the debt. The family wanted to default on the debt by relying on their numbers, which made Mingfei very unhappy, as if they were the creditors. It seems that they are used to being overbearing, but this time they met the magician Mingfei, who turned them into tiny people and asked them to repay in other ways...
