[Era + Crime Solving Cheat Finger + Unit Story + No CP] Meng Changli is a graduate student majoring in criminal psychology in the 21st century. She died in a car accident and was reborn in 1980 as a returned doctor who had the same name and same age as her. He was originally a genius in criminal psychology. He was assigned a job and housing as soon as he returned to China. Meng Changli originally thought that as long as he worked hard to maintain his "expert" persona, he could live a stable life with the iron rice bowl left by his original self and wait for retirement. Until the police came to ask her to help solve a serial murder case... Meng Changli suddenly discovered that when she came into contact with the victim's personal belongings, fragments of scenes from the crime scene would sometimes appear in her mind. Relying on two generations of knowledge reserves and the blessing of golden fingers, Meng Changli repeatedly solved strange cases and became a treasure in the eyes of police everywhere.

Times will change, but the desires and greed hidden deep in human nature will not. If you're not careful, Meng Changli becomes a dazzler for criminals. So much so that criminals are spreading rumors—— Don't mess with that hypoglycemia expert! She only needs to touch the evidence to find the murderer!
