Lu Jiandeng, a mirror repair girl from Nan City, received a bloody and broken mirror on a rainy night, and unexpectedly awakened the "cold scale mirror" that can reflect the blood debts of old cases. Following the afterimage in the mirror, she traced the Wei family murder case and the old Qinghe case all the way to the depths of the Yan Mansion, the Embroidery Department and the palace walls, uncovering the dark accounts of power behind the Cui family's unjust case ten years ago, the internal treasury military pay, the fake edict and the Hundred Mirror Array. She joined forces with Yong Chibai, Ruan Sangeng and others to seize evidence and overturn the case amidst the pursuit and lies, so that the erased names could be seen again.
