I Investigate Crimes and Cultivate Immortality in Another World

When he woke up, Xu Qingfeng, a modern elite detective, became a clerk waiting for death in the archives of the Xuanjing Division. Because the original owner offended his boss, he was thrown into a dead file filled with hundreds of years of unsolved cases. The first case that Xu Qingfeng took over was the "Painted Skin Case" that would shock the capital in three days. With the help of modern criminal investigation thinking, he saw through the mystery, but the man behind the scenes was silenced. In a desperate situation, he touches the deceased's relics and unlocks the "Crime Illustrated Book" in his mind - not only can he trace back to the crime scene, but he can also deduce techniques and extract characteristics from thousands of sins! Xu Qingfeng relies on the "Illustrated Crime Case" to cultivate Taoism with cases and break situations with force. He has been working step by step from a humble official, dealing with the Xuanjing Division, Jianghu forces, and the remnants of evil cults. Everyone thinks he is a nerd who relies on luck to investigate cases, but they don't know that he has already turned his sins into treasure, stacked up his passivity in the darkness, and become a saint with stability!
