Xuanjing Division, the death examination yamen secretly established by the imperial court. The female officer in charge of the camera, Shen Yan, has a skill that shouldn't exist - making a mirror from ashes and mercury to see the soul of the deceased returning home.
She has no memory of before she was sixteen. I just remember waking up with an old bronze mirror in my arms. A woman who looks exactly like her often appears in the mirror, combing her hair in front of the mirror. Every time you comb it, your face becomes rotten.
She told no one about it.
People began to die in the capital. The legitimate daughter of the minister's house died in front of the makeup mirror, the painter's entire body disappeared out of thin air, the causes of death of the twin sisters were interchanged, and the deceased daughter in the ossuary coffin of the ghost marriage spoke. The bones of all the dead were inverted, and their souls were no longer where they were, as if they had been dragged away from the mirror by something.
During the investigation, she met Rongdu, the executioner of Dali Temple. He was investigating his brother's death, and the clue pointed to the old bronze mirror on her waist. The two of them each have their own secrets, are on guard against each other, and cannot get away from each other.
The clues go all the way down. Under the palace, a Ten Thousand Mirror Array that had lasted for three hundred years was crumbling. The world in the mirror traps the dead souls. They have consciousness and memory, but they can't come back. Every time the formation weakens, the things in the mirror seep out.
Shen Yan didn't know that the truth she had been chasing all the way ended up with her.
The woman combing her hair in the mirror is no one else.
