A group of ordinary people from all walks of life suddenly find themselves in the "Land of Finality." Here, they are trapped in a ten-day cycle of life and death, with their memories wiped clean after every reset. To escape, they must constantly wager their lives in deadly trials hosted by the "Twelve Zodiacs," engaging in psychological warfare and battling both the hosts and their fellow players with strength and wits. Trapped within this nightmare, Qi Xia is driven by a single obsession: to return to reality and save his wife from imminent danger. As the ten-day cycles repeat, a supernatural power known as "Echo" begins to awaken within certain players. Slowly, Qi Xia and his companions start recovering their sealed memories, uncovering the perilous truth behind this bizarre world and their intertwined fate with the Land of Finality. Armed with his unparalleled intellect and the diverse "Echo" abilities of his allies, Qi Xia leads his companions to defeat the enemies of the Land of Finality and carve a path back home.
