The hospital's CT machine has become the "eye" connecting life and death for unknown reasons. Lin Yi accidentally "awakened" this ability due to extreme mood swings and accidental electromagnetic interference during a night shift rescue. The "wronged souls" he saw through CT scans were not ghosts in the traditional sense, but more of the strong emotional energy left by the deceased, unresolved obsessions, and even "information fragments" in the form of abnormal electromagnetic energy. These images often appear as ghost images, unexplained artifacts, abnormal tissue density, or mirror images of internal organs.
