Chang'an Investigation Bureau

My name is Shen Du, I am in charge of archives at Dali Temple and I am a coward. Master left me a "Collection of Investigation Reports on Abnormal Events", which records the solutions to hundreds of strange cases. The problem is - all the key pages have been torn apart. In the city of Chang'an, the reflection in the mirror imitates a living person, the sound of drums at midnight can draw away the soul, and non-existent shadows appear in the Daming Palace. Every time I thought I found the answer, I turned to the next page and there was only one line: "This method cannot be reused." I can only bite the bullet and do it myself. By the way, my partner is a sociopath who doesn't talk and only eats jujube cakes. But she never hesitates when she chops things. In the prosperous age of Chang'an, there are some things that the common people cannot know. And we are the ones responsible for keeping them unaware.
