This is a world where angels and humans coexist.
In order to prevent angels from disrupting the order of the human world, the heaven signed a contract with some people in the human world who had committed crimes and wanted to be acquitted, requiring these people to get rid of the angels who frequently descended to earth and caused chaos in the human world. In this way, these people can not only be acquitted, but also have a high degree of mission completion, and can re-exist in the form of human spirits after the natural death of the human world.
Purpose: Carry forward socialist core values
