On July 17, 2025, the night of the blood moon, a "spiritual vision phenomenon" broke out worldwide. A bloody countdown suddenly appeared on human retinas. When the number reached zero, the barrier between the real world and the strange dimension completely collapsed.
In the city, neon signs began to ooze thick plasma, the sound of children grinding their teeth in laughter was heard from deep in the subway tunnels, and videos of "people in the mirror blinking" went viral on social media. The banking system was completely paralyzed within 72 hours, and banknotes that once symbolized wealth were burned by citizens as talismans to ward off evil spirits. Little did they know that the real strange currency had long been circulating in the shadows.
The global population plummeted by 47%, and survivors huddled in makeshift "purification zones", using cinnabar to draw crude spells on doors and windows. In the ruined city with distorted rules, the laws of Hades are replacing the order of human society - traveling during the underworld requires paying underworld money to the earth temple, and when you hear a knock on the door late at night, you must splash the door with black dog blood. Only those with special underworld weapons can take the lead in supernatural events.
