Fang Jingran and Jiang Shixi were thrown into a "secret realm where you can make bets." Each time they passed a level, they had to bet on survival or compensation. The rules of black humor were written in cold reminders, but the opponent could always win the price from "the secret you don't want to admit." The more they struggle, the more they feel like they are working for the system, until they discover that the ending of this infinite reincarnation actually uses the relationship between two people as a bargaining chip.
