The end of the world has come, and the fog-shrouded area has become an independent space, with weird rules running in it. If you violate it, you will die. Rules analyst Chen Du makes a living by selling rule information. This time, the Shelter Group offers a price he can't refuse: a high bounty, life-saving drugs, and a quota to the safe zone. The condition is to enter the S-class foggy area where no one has ever brought back the complete rules. The group assigned three teammates who did not know each other: the silent veteran, the psychic perceiver, and the data-addicted technician, claiming that this was the "optimal configuration." When the fog swallowed everything, the rules began to twist, and they discovered that there was only one real rule in the S-class area: the way to get out alive, written on the moving wall.
Purpose: To explore the boundaries of human nature between trust and betrayal in extreme environments. Use the weirdness of rules as a mirror to reflect the fear of being bound by invisible rules in real society. Science and the supernatural are intertwined to ask what people should believe when the laws of the world are no longer knowable. Rules can be recorded, but those who understand the rules are often the first to become victims of the rules.
