Gu Qingci, a modern forensic doctor, transformed into a uniformed servant at the bottom of the Dali Temple. While struggling to survive, he discovered that he could empathize with the deceased - by touching the relics, he could see the last memories of the deceased.
In an "accidental drowning" case, she discovered the truth behind the murder, but she also fell under the control of Lu Hanjiang, the commander of the Prison Department. This man, who was known for his ruthlessness in both the government and the public, gave her two choices: to be eliminated as a suspicious spy, or to become the knife in his hand that cuts through the fog.
From the mystery of the city to the mystery of military achievements, from the marriage of ghosts and suspected poison to the surprise of the palace banquet. Gu Qingci uses modern forensic science as his bones and empathy as his eyes to piece together the truth among the bones. Gradually, around her, a young man from an aristocratic family obsessed with machine arts, a former courtesan with an intelligence network, and a loyal veteran gathered around her - a group of "marginal people" who were not accepted by the mainstream and became the sharpest blade to pierce the darkness.
However, each case is like a spider thread, vaguely pointing to the same buried murder. The recurring burning mansion and the shadow of a child in a dry well in her dream, and the "Old Shuobei Case" that Lu Hanjiang was secretly pursuing, were actually intertwined under the light of the bronze arrowhead of the evidence. When the boundaries between chess players and chess pieces begin to blur, she must answer: Is she paving the way for power, or is she seeking a home for the dead?
The bones can speak, but the memory will never die. When the forensic doctor's rationality meets the shadow of ancient times, she chooses to carve a testimony for all the voiceless people that will not be erased by time.
Purpose: Skeletons serve as a mirror, empathy serves as a blade, and in the deepest darkness, speak for the silent and draw a sword to those who are plotting.
