In ancient times, officials like Di Gong would set up mock trials in the underworld to crack adultery cases, and Bao Longtu would disguise himself as King Yan to scare the real perpetrators into confessing.

Similarly, Xu Qing did not possess the ability to question the underworld, but he could read the Sutra of Salvation to view the deceased's memories, returning to the crime scene to watch a replay of the government official's death.
The government official who died under mysterious circumstances before him was named Wei Fang. Since his grandfather's time, his family had been in this line of work. By his generation, it could be considered a well-established tradition.
