In the thirteenth year of Jinghe's reign, seven consecutive cases of death of brides occurred in Yong'an City.
Seven women all died on their wedding night. There was no murder weapon, no injuries, and no clues that could point to the murderer.
Everyone believes that this is an unsolvable mystery. Only Shen Yan, the prosecutor of the Inspection Department, believes that there are no unsolvable mysteries in the world, only the deeper truth.
In order to find out the case, he teamed up with the calm and intelligent prosecutor Ning Wan to investigate, but found that behind the seven deceased people, they all pointed to a mysterious organization-Tianji Pavilion.
They study people's hearts, record behaviors, and can even predict a person's choices in advance.
When Shen Yan got closer to the truth step by step, he discovered that this serial case was not for killing people, but to verify a crazy plan.
If people's fate can be predicted, do people still have the power to change the future?
In this chess game about truth and destiny, Shen Yan and Ning Wan have become the two most important variables in Tianji Pavilion.
