The King of Hell, Shen Yuan, was in a state of distress in the underworld because his wife Xu Nian in the underworld was too obsessed with her. In order to "live in the same quilt and die in the same cave" with him, Xu Nian not only bought the adjacent cemetery, but even used law, metaphysics and even the magic weapons left by her husband. His powerful obsession actually broke through the seals of the eighteenth level of hell and released the ancient demon! On one side is the monstrous evil energy that is about to overturn the underworld, and on the other side is his beloved wife who is still "making trouble" in the human world. Shen Yuan is caught in an unprecedented dilemma. This is a fantasy story about love, obsession, and how an "unconscious" wife turns the underworld upside down.
