Twenty years ago, his father disappeared mysteriously while investigating a case. Twenty years later, Qin Muchuan inherited his father's career and became a policeman. On his first day on the job, he touched the wound of the deceased, and an image of the murderer cutting his throat with a license appeared in front of him - he could read the remaining memories in the physical evidence! Since then, Su Zhuo has relied on this incredible skill to solve strange cases repeatedly, including card murders, ghost coin poisonings, mercenary revenge, serial kidnappings, etc. As long as the criminal leaves traces, he has nowhere to hide. Crime tools, fingerprints at the scene, wheel marks, every touch is the key to the truth. What's even more amazing is that every time he solves a case, he can acquire a god-level skill, including card throwing, explosive disposal, and god-level skills.
