Han Ji woke up in the seventh district of Nomadic Skeleton City, and his fingers could feel the reverberation of emotions that others could not touch. Three months ago, his partner Yin Que mysteriously disappeared in the "Riemann Curved Street". The official conclusion was that the curvature of grief exceeded the standard. Han Ji didn't believe it. His precognition ability told him that three seconds before Yin Que disappeared, he saw a man - a man who should not have appeared on that street. In the process of tracking the reverberation, Han Ji discovered that all the rules of ghost stories have a common mathematical flaw. What's even weirder is that whenever he gets closer to the truth, someone will intercept him in advance. It's not a leak, it's someone who can predict his prediction. Until Silverfish slapped a substitute contract in front of him: "You and I are both dimensionality reduction carriers for some high-dimensional existence. Do you think you are solving the case? You are just being fed as bait." Han Ji silently opened the fourth volume of the Advanced Mathematics Handbook. He doesn't need to escape his double identity. What he wants to do is to let that high-dimensional subject die for him.
