Reasoning System: Start by Becoming a Suspect!

On the twenty-seventh day of school at Jiangzhou University, Lin Mo, a freshman in the Department of Mathematics, became the only suspect in a murder case. Campus anchor Xu Wan died in a locked studio. Surveillance showed that only Lin Mo had entered the scene at the time of the crime; his fingerprints were left on the murder weapon; and the last unsent text on the deceased's cell phone was: "Lin Mo is here." In the interrogation room, the criminal police asked him why he killed. An interface that only Lin Mo could see appeared in front of him at this moment. [Case loading completed. [Police's current conclusion: Lin Mo committed murder. [Logical completeness: 91%. [Unexplained contradictions: 5. The system will not tell him who the murderer is, nor will it send evidence out of thin air. It can only help Lin Mo sort out the timeline, verify assumptions, and reconstruct the logic of the case. To clear his suspicions, he must find out those five contradictions himself. Lin Mo soon discovered that everyone was investigating how he entered the secret room to kill people. But the real problem is—— Xu Wan in the live broadcast was already dead at the time. After the first murder case was solved, Lin Mo unlocked the timeline interpretation. After the second murder case ended, he obtained the on-site space reconstruction. After that, there was trace correlation, testimony analysis, behavioral modeling and criminal psychology deduction. Police have the experience, technology and investigative authority. What Lin Mo possesses is a set of constantly growing reasoning abilities.
