The once-in-a-century heavy rain washed away the embankment, the water receded, and the cracked ground revealed a male body that had been sealed for many years. The investigation found that it was Jiang Xiyan, the top scorer in the college entrance examination, who disappeared ten years ago. The criminal policeman Song Zhou, who was in charge of investigating the case, worked day and night, but he still couldn’t hold back the great sleepiness and laid down at his desk to rest. While half asleep and half awake, he received a call. The caller claimed to be Jiang Xiyan and was being hunted down. He hoped that the police would rescue him. Song Zhou thought that someone had the same name, but he didn’t expect that the place names mentioned by the other party were all the locations that had been demolished, and the time Jiang Xiyan mentioned was exactly three days before he was confirmed missing. Regardless of whether it was a prank or a real occurrence, out of responsibility, Song Zhou still helped him out of trouble, but he was surprised to find that the evidence in his hand was also changing. In other words, the other party might really be Jiang Xiyan, who died ten years ago. —Uncle policeman, can I trust you? Can I survive? —Yes, trust me, and trust yourself too. —If I survive, I want to see you.
