When I knew that there was another accident in the orphan girl's grave, I could hardly remember the first few times, this lonely grave camp located on the embankment of the Yongding River had been several generations, before moving out of the village, the old man had said that he promised that within fifty years, nothing would happen again, and it was less than thirty years later, and there was a boy who collapsed in the orphan girl's grave, indicating that the grave camp must have been moved, or that someone had broken the spell that the old man had put down.
