Back to 1983: I Solved the Case Crazily Based on My Memory

Qin Feng, before time travel, was a 60-year-old veteran criminal investigator from the Criminal Investigation Detachment of Nanzhou City Public Security Bureau who was about to retire. He had cracked more than a thousand major cases in 40 years of work. He accidentally crossed over due to a suspect during a border arrest; he was a 20-year-old newcomer who had just started working in 1983 under the background of severe crackdowns. He was in good health and retained a complete set of criminal investigation experience and major case context. With the memory of 40 years, he can always solve the case in the shortest time. He can solve the old cases that were shelved at that time in advance based on his memory. He can predict and prevent upcoming serious cases in advance, protect colleagues, protect the public, and protect people's names and property.
