Doomsday Jigsaw Puzzle

When twelve doomsday clocks are suspended in geosynchronous orbit, humans around the world are forced to participate in a jigsaw puzzle - traveling through different collapsing parallel worlds to seize core fragments of civilization to delay the countdown to doomsday. Delivery boy Chen Yuan triggered a paradox when he traveled through time for the first time: what he brought back was not a fragment of civilization, but a pocket watch that could reverse time. Since then, he has become the only player who can save and load files in Doomsday. Traveling through a cyber city besieged by zombies, a silicon-based world where mechanical ascendants slaughter flesh and blood, a medieval kingdom corrupted by the old rulers... Chen Yuan gradually discovered that the so-called jigsaw puzzle was actually a scam used by higher civilizations to harvest human souls. And every time he looks back on his death, he is tearing apart the shocking conspiracy behind the curtain of doomsday. This novel and its characters are purely fictitious.
