Su Lan never dreamed, until one night, an invisible mirror shattered beside her ear. When she woke up, the world shattered into countless broken fragments, the familiar streets turned into a twisted maze, and shadows whispered among the crowd. She finds herself involved in "Border Protocol" - a terrifying game of manipulating parallel worlds, where every step she takes may trigger the collapse of reality. Su Lan's only motive is to find her forgotten self, but every time she travels through time, she continues to lose her memory, and even doubts whether she still exists. The highlight of the story is that each world reflects her deepest fears and desires, poignantly questioning her origins. As the border becomes increasingly fragile, Su Lan must make deals with the monsters peering through the cracks, and even question: Who is controlling the rules of the world? This is an adventure that depicts the cracks in human nature and the distortion of the truth. Horror and suspense go hand in hand, taking you step by step deeper into the unknown.
