A countdown to life appears on the wrists of eight billion people, and everyone who has had a brush with death is pulled into the "Corridor of Ten Thousand Mirrors." There is one dungeon for seven days. The seven deadly sins and the seven virtues are judged in turn. Death in the dungeon is death in reality. Two people who should not have survived met here - they were each other's blade and scabbard, and they were each other's only proof of innocence on the scale of good and evil. When the final trial is revealed, the so-called screening rules are far more cruel than they imagined: they are not looking for good people, but survivors who can walk the tightrope between crime and morality.
Intention: Seven Deadly Sins and Seven Virtues, Human Good and Evil
