Delivery worker Yang Xiaofeng was accidentally involved in the case of a missing pet in the community, and activated the "Clue Fragments" golden finger - when the key items in the case were touched, the brain would automatically splice scattered clues and trigger a nonsensical reasoning barrage. Under the "coercion" of Su Rong, the eccentric daughter of a wealthy family, he was forced to return to his old job (a former criminal policeman who had resigned due to being framed). Starting from solving small neighborhood dispute cases, he gradually uncovered the main mystery of "the mysterious death of his master five years ago." There were frequent jokes during the process: using a takeout box as an evidence box, being robbed of credit by the cat owner, being "kidnapped" by Su Rong's private plane to investigate the case... In the end, the transformation from salted fish to private detective was completed within 400 chapters, and the grievances of the past were cleared.
