The Death Train is a means of transport that carries souls to the underworld. Among the Death Trains, one red train is reserved for the most wicked and vile people. It can transmigrate through any parallel world and forcibly send such people to the netherworld, where they will never be reincarnated.
Whenever the red Death Train appears, a livestream begins to warn the world that evil deeds will be punished. If it hasn't happened yet, the time simply hasn't come.
Time goes on, and the livestream never stops. At any time and in any place, whenever someone truly wicked appears, the livestream will show up in any streaming room.
