I Solve Murder Cases by Backtracking

My name is Lin Chen, the youngest trace examiner in the provincial department. Now I am a suspended prisoner, the number one suspect in the deaths of six people. All the evidence points to me - fingerprints, DNA, crime plan, perfect closed loop. Until I touched the broken lighter. I went back to the rainy night when the crime happened and saw the face of the real murderer with my own eyes. That was my immediate boss, the person in charge of the task force, the person who personally sent me to death row. What's even more desperate is—— Every time I go back, I have to bear the pain of the victim being killed. Every time I go back, I am absorbing the murderer's murderous intent and personality. 12 Times, 12 lives. After the 12th time, I will become him. Outside, my only sister was being stared at by the real murderer. Inside, the murderous intention was getting crazier in my mind day by day. I'm out of time. I want to get out alive and send him to death row with my own hands. Even if the price is, I will become a ghost first.
