Lu Shubai cuts off seven paths to survival with his own hands, all to retrace time and space and reclaim the life Shijin erased himself. He is no longer the gentle, jade-like genius physician, but a madman who walks the boundaries of the rules, trading life for life and soul for soul. Shijin, a forbidden enforcer as silent as a blade, was once Lu Shubai's only light. Now he has become the fate Lu Shubai must destroy with his own hands. As time begins to flow backward and memories are torn apart and remade, the two face each other in a rain of blood: one must save, the other must kill. But who still remembers that the life in question was won through the heartbeats they shared?
