Ghost Spirit Recovery: I Have a Sign-In System

In this era of resurgent ghost energy, Xie Xuan got a sign-in system, but the place where he signed in every time was a little wrong... A spooky and secluded cemetery? A deserted art room in the middle of the night? A hearse bound for the underworld? … This* system is making it difficult for me to thank someone. The ghost energy is revived in the early stage, and the spiritual energy is revived in the middle and late stages. This novel and its characters are purely fictitious.
