In a future world, human genetics are set to stay at 25 years of age, no matter how long they live, their physical characteristics will remain at 25 years old. However, by the age of 25, everyone can only live for a maximum of one year. The only way to continue to live is to get more time through various channels (such as work, lending, trading, selling, and even robbery). Then time became the currency of circulation in this world.
Bank-like time management agencies are spread all over the world, and time guards track and record each person’s time and remaining time like a policeman. Once the amount of money in the time bank is left, they will be deprived of their lives. Rich people can live forever, and the survival of poor people becomes very difficult. Once the watch on the arm is cleared, it represents the death of a person.
