Messenger from the Underworld

My name is Chen Shi, I am 19 years old this year. Because of my grandfather's dream, I decided to return to the remote town of Chenjia Village after leaving for many years. From this moment on, I embarked on a road that ultimately made me unable to look back! The underworld is revealed, the messenger is established, and the dead souls return to my service! The mortal world is open, cause and effect are fulfilled, and you can enter reincarnation freely! Welcome to Chenjiayi, a place where living and dead souls are traded!
