As fewer and fewer people recognize your face, your existence begins to unravel. That is the rule of the “Cognitive Cage.” Chen Wei and his two closest friends are dragged into a strange world where death doesn't come when time runs out, but when you are “forgotten.” Every supernatural game is a gamble with perception: win, and you slow the world's erasure of you; lose, and everyone forgets you faster. Chen Wei must use his extraordinary intellect to find loopholes in the rules, choose between his friends and survival, and uncover the ultimate truth of this world that devours memories.
