Living and Dead Pile

My grandfather was the last mountain warrior of the Northern Sect. Before he died, he told me never to touch anything underground. I didn't listen and followed a group of southern natives down a pigeon hole from the Tang Dynasty. As a result, there was no coffin in the tomb, only a fresh female corpse sitting on a white jade chair, wearing a red wedding dress. The bronze bell tied to her ankle is exactly the same as the one my grandfather left me. What's even more terrifying is that my teammate suddenly grabbed my neck and said, "Your grandfather nailed her here back then. Now it's your turn to repay the debt."
