In 2157, after the “Quantum Tide” disaster, Earth became a graveyard of time and space. Transparent, humanoid creatures known as “Time Wraiths” roam the ruins of cities. They are the lingering shadows of victims frozen in temporal rifts. When humanity discovers that the Wraiths can delay their own quantumization by devouring the consciousness of the living, the last bastion of civilization, “Dome City,” becomes a slaughterhouse for minds. Lu Linyuan, a genius physicist suffering from retrograde memory hyperplasia, is forced to take part in the “Shadow Reaping Program.” There, he discovers that every Wraith contains a countdown light cone. And the most dangerous SSS-rank Wraith, “Red Falcon,” turns out to be his quantum mechanics partner, the special forces sniper Jiang Weixi, who “died” three years ago.
