Dayin used the "official time" issued by the Tianheng Department to determine the authenticity of the edict, and also decided whether the deployment of troops, executions and pardons were legal.
Twelve years ago, the Shen family in charge of Tianheng Tower was convicted of the "Hetai Case". The only survivor, Shen Zhaowei, kept his name anonymously and became a master clockmaker and engraver.
Twelve years later, she discovered during a public execution that Zhaojing actually rang the noon bell twice on the same day: at noon on the first day, the insider was killed and the frontier troops were transferred, but at noon on the second time, the deceased was declared innocent with a legal pardon.
In order to track down the secrets left behind by her father, she was forced to join forces with Xie Heng, the young minister of Dali Temple, to extract clues from the incised teeth marks, the underground waterway with countercurrent flow, the records of the living and the dead, and thirteen abnormal bell vibrations.
As the old case was reopened, the eldest princess, Prince Ning, the chief minister and even the emperor were involved in the chess game one after another. Shen Zhaowei gradually realized that what the person behind the scenes really controlled was not a clock, but the way the entire dynasty determined the truth.
When two sets of equally legal time are activated again, she must reveal the truth that has been buried by power for twelve years before the next noon clock rings.
Purpose: When power can define time and truth, the only way to maintain justice is to allow evidence to be witnessed by everyone.
