Weird Records of Daqian: I Killed the Yin God by Touching the Bone Pit

In the last years of the Qian Dynasty, before the demons appeared, Taixu descended first. In order to repay a debt, the down-and-out undertaker Guo Chao mistakenly touched the death contract jade tablet on a headless corpse and was forcibly dragged into a fantasy world based on real ancient tragedies and folk customs. The rules here are strict, and if you answer wrong, you will die. Guo Chao relied on his talent of hearing bones to form a superficial alliance with the cold-blooded female killer Su Qinghe. In the Human Skin Workshop and the Zhizha Blood Village, Guo Chao discovered that behind those fatal rules, there was actually a secret about the longevity of the Daqian royal family. And every last word of the deceased he heard in his hands was piecing together a truth that sent shivers down his spine. The first suspense is raised here: Why does the headless corpse with the death contract have the same birthmark as him?
