A never-ending rainstorm dragged Lin Yan and Su Xiao into an endless strange story called "Rain Curtain Rules". Each copy is shrouded in sticky rain and mist, and weird rules are written on damp pages: "Do not look directly at the figure outside the window after midnight" "Do not accept black umbrellas from strangers on rainy days" "If you hear water dripping from the roof, you must turn off all faucets immediately"... Those who violate the rules will die in a bizarre way, and the cold touch of rain will always remain on the body. Lin Yan relied on the keenness of forensic medicine to dismantle the rules and traps, while Su Xiao used a paintbrush to capture the terrifying truth behind the rules. The two supported each other in countless heavy rain copies, but found that each time they cleared the level, they just stepped into deeper despair - this infinite flow has no "exit" at all, and all participants will eventually become sacrifices in the rain curtain, and no one can escape. They have seen their companions melted into pus by the rain, and they have seen people swallowed by their own shadows because they misbelieved in the rules. As the copy goes deeper, Lin Yan discovers that the rules in the ghost story are actually related to the truth about the death of his partner many years ago. Su Xiao's oil paintings also begin to show scenes of two people dying. The fear in the rainstorm not only comes from the rules, but also from the inescapable fate.
Purpose: To explore the struggle and alienation of human nature in an environment of extreme terror and despair, and to reveal the cold truth hidden behind the "rules" - in the endless cycle of death dilemma, there is no real salvation, only endless fear and destruction, to show the insignificance and powerlessness of human beings in the face of irresistible fate.
