When forensic doctor Lin Xi's fingertips touched the cold body, the whispers of the deceased echoed in her mind. She holds a "psychic system", but she is not a superstitious witch, but the most rigorous evidence hunter. She demands "verifiable clues" from the undead - a hidden scar, the distinctive dent of a murder weapon. Under the blue light of the DNA laboratory and in the trajectory of ballistic analysis, she used science to verify the testimony of the deceased. Faced with the fog of "human sacrifice", she followed the fragments of the deceased's memory to locate the altar in the wilderness, and recorded this conversation that transcended life and death with a voice recorder. She establishes "credibility ratings" for the testimonies of the dead, and ambiguity is "illusion." Lin Xi is using cold rationality and fiery persistence to open up an unprecedented path of "spiritual evidence" in the gap between science and the supernatural, allowing the whispers of the dead to become the glimmer of light that illuminates the truth.
