People Dig Graves, Ghosts Bury Them

The mountains hide ghosts and spirits, and gods and demons live among them. It is not easy for people in the mountains to enter reincarnation after they die, and the things in the mountains don't want to let them go. If you want to leave, you need someone to take you with you. A living person digs a grave, a ghost person goes into hiding, and you enter the grave and return to the ghost world before you can go on the road. If you don't take this step, you won't be able to enter the underworld. You will enter the mountains, and the things in the mountains will make your soul disappear...
