I Rely on Resurrecting Corpses to Become a Detective

I, Lin Mo, am a pauper who owes a lot of debt and is waiting to die in a village in the city. Until I picked up a special ancient coin, which was bound to a system called "Resurrection of Bones". Others solve the case and find evidence, but I solve the case and directly charge money to the dead person. As long as the money is in place, the deceased can personally tell you who the murderer is, what happened at the scene, and even the model of the murder weapon. But the problem is that this system is a gold-eating beast. It is worth eighty-eight thousand yuan a time and will go bankrupt for a whole year if it is resurrected for one minute. In order to pay off the debt, I became the police's most mysterious consultant, specializing in solving old cases that gave the police a headache. They thought I was a detective with meticulous reasoning, and that I relied on paying dead people. It wasn't until I took over the famous "Headless Corpse Case" that I saw the last memory of the deceased, and the murderer was smiling and making a silent gesture to me. He seems to know my existence.
