Traveling into Feng Kai, I Activated the Hummingbird System

[Tag] # across # criminal investigation # system flow # chronology # double male protagonist # dimensionality reduction strike Criminal investigation expert Feng Kai accidentally activated an old "Hummingbird" trace extractor while investigating a disappearance case that had been buried for 28 years - a blue light flashed, and he traveled through time and became a small policeman in 1976. No DNA, no surveillance, no spectrometer. The police station relies on "self-inflicted crimes and gangsters" to solve crimes. Before Feng Kai had time to adapt, a female worker in the cotton spinning mill died mysteriously. Director Song determined it to be suicide. He lowered his head and saw: strangulation marks, strange shoe prints, cloth shoes stained with red soil - this was obviously a homicide! But he was just an educated youth who had just returned to the city. Who would believe what he said? At the critical moment, a thin, silent young man carrying a broken wooden box stood up. Gu Hongxing, the only technician in the institute who believed in physical evidence, was ridiculed by everyone as "Gu idiot". Feng Kai looked at his hands covered with aluminum powder and dust, and suddenly understood the meaning of "hummingbird" - when everyone is rushing forward, there is always someone hovering in place, searching carefully for the truth. System prompt: Hummingbird Fire System has been activated. The fusion degree is 1%, and 100% is required to unlock the way back. With forty-five years of modern criminal investigation knowledge, Feng Kai teamed up with young Gu Hongxing to rebuild the chain of evidence in the technological wasteland, starting from a incomplete fingerprint and an inconspicuous grain of red soil. Not only did he want to rewrite the outcome of this murder case, but he also wanted to make up for the regret that had haunted him for twenty-eight years—— This time, the truth will not be silenced.
