People and even some creatures or objects that have been with people for a long time will have strong obsessions, and the obsessions will become stronger and stronger. Gradually, the bad gases generated by these obsessions, such as guilt, dissatisfaction, and complaints, accumulated more and more and became a mountain invisible to humans. In the eyes of those who have practiced spiritual practice, it can be seen as black and dense, and this mountain is also called Wushan. Because of Gong Yuan, I was accepted by Master Zhenyuan and became a closed disciple. I stayed in Wushan and started practicing. However, after practicing for less than a month, my master told me that my obsession with the world of mortals was too deep, so he asked me to leave Wushan and return to my previous living environment to practice while resolving my resentment and regrets within my capabilities. Before I left, Master Zhenyuan also gave me a new name: Wu Xin. From then on, I was Wu Xin, and I also changed my name to Wu Xin when I lived in the secular world.
This book records the strange ghost stories that happened after returning to the secular world.
