Passenger Without Ticket

He did not buy a ticket, but died in the bathroom of a fully enclosed high-speed train. He had no wounds, but his internal organs felt like they had been crushed by giant hands. He disappeared for five days, and the carriage where his body was located was on the maintenance line thousands of miles away three days ago. The case that physicist Shen Mu took over had three words written from beginning to end: impossible. He used thermodynamics to dismantle the secret room, used aerodynamics to review the trajectory, and finally found a few twisted hairs and a dry nail. On the day the case was solved, Shen Mu walked on the overpass alone. He looked at the silver dragon moving under his feet and finally understood: the mounted carriage was not an accident at all, but a mobile steel morgue specially prepared for him.
