Meandering and disappearing into the heat wave in the distance. I squatted on the roadside and poked the series of footprints on the ground with my fingers. The footprints were deep and had neat edges, as if someone had deliberately stepped on them, more like they had been pressed out by something heavy. Lin Xing, please say something. Murong Xingchen stood behind me, wrapped tightly in sun protection clothes, only his eyes were exposed. There is not even a ghost in this ghost place. Do you have to say that someone is missing? I ignored him, took out my phone and took a photo. The signal bar has long since returned to zero, and this crappy phone is just a brick now. Look at this. I pointed to the footprints. When a normal person walks, there will be a trace of forward sliding when the sole of the foot touches the ground, but this one did not. Press down vertically and lift up vertically. Murong Xingchen knelt down and took off his sunglasses. He squinted for a long time, are you saying this wasn't a human being? Maybe it's a machine. Machine? He stood up and patted the sand on his hands. Don't tell me there are robots in this desert. I didn't answer, stood up and looked into the distance. The oasis is just ahead, and the treetops of the Populus euphratica forest are faintly exposed. This oasis called Crescent Bay cannot be found on the map, but the name is indeed marked on the navigation. Three days ago, a girl named Su Wanqing posted a message asking for help on social platforms. She said she was trapped in Crescent Bay and someone wanted to kill her. Then the account was canceled. The police investigated and said she had a mental problem and often posted incomprehensible things.
