In Chang'an City, everyone has a destiny file.
It records a person's birth, encounter, and parting, as well as when, where, and how he will end his life. No one knows their own "luck", and Qin Tianjian is responsible for guarding this order that no one can see.
Some people accidentally deviate from the established life, and some people go to places they shouldn't go because of a wrong choice. Small deviations can be guided, serious deviations need to be corrected. For thousands of years, Qin Tian Jian has maintained the operation of Chang'an in this way.
Until archivist Bu Yifan discovered a file that shouldn't exist.
The person in the file has already finished his "luck", but he is still alive.
He knows Qin Tian Prison, he also knows his own destiny, and he even knows how to escape when fate comes knocking on his door again and again.
As the two met, a series of seemingly unrelated anomalies surfaced one after another: someone was clearly dead, but left new traces many years later; someone just made a trivial choice, and his entire life began to deviate; and some files that had been dusted for many years are reappearing.
Some files are sealed not because they contain a person's secrets.
It's because there are secrets hidden in it that even Chang'an cannot know.
Concept: There is no destiny in the world, only your own choice
