In the Face of Mental Illness, What Is a Ghost?

Su Ran traveled from another time and space, but became a mental patient due to time and space confusion. In a world where ghost energy is resurrected, the system failed to cure Su Ran's mental illness. The system is also broken, saying that it only provides technical support. So there is a system for mental illness. From then on, Su Ran was a ghost, and ghosts ascended to heaven. This novel and its characters are purely fictitious.
