Introduction:
When I was 20 years old, I found an ancient coin in an old village on the southwestern border. The front of the coin is engraved with the words "Netherworld Tongbao", and the back is engraved with the four hexagrams of "Kun, Xun, Li, and Dui", which have been covered with rust due to their age. Locals told me that this ancient coin is called the ghost money, and the legend says that there were originally four of them, and during the Tang Dynasty, a scholar used the other three ancient coins to buy off the ghost cha, and secretly infiltrated the palace of Hades to tamper with the book of life and death. I don't know if the legend about the scholar is true, but I do know that this ancient coin is closely related to the disappearance of my parents and the mysterious death of my second uncle. In order to unravel these mysteries, I decided to delve into the story behind this ancient coin and discover the secrets hidden within.
