A city of sin corroded by desire, a ten-year murder saga woven with memories.
In Stano City, where neon lights and blood intersect, Su Yue, the deputy inspector of the patrol room, carries an unspeakable secret - she has the power of a "mind mirror" and can see into the deepest darkness of other people's memories. But every time she uses this ability, she must endure the extreme pain and madness of the memory of the original owner when he was dying.
The blue mist of isophorin spreads underground, and the snake ruler measuring the door squirms in the darkness.
From a mirror holder to a ruler holder, from a secret peeper to a chess player.
The real enemy, Ling Wuya, the supervisor from the Measurement Sect, never wanted to control her abilities, but to completely destroy the "Heart Mirror" itself, so that all the clues Lin Zhengnan had buried with his life would be cut off along with his bloodline.
When the last heart mirror was shattered in the bloody battle, Su Yue stood on the ruins of the Public Inquisition of the Government Affairs Department, holding the blood-stained Tianliang Seal in her hand.
This is a game of memory and power, a psychological secret war that spans ten years. In Stano City's darkest moment, Su Yue will prove that the sharpest weapon is never a mirror that can peek into secrets, but the determination to dare to measure good and evil and to sacrifice everything for it.
