In the "Iron Law Academy", the fate of all heroes follows an unchangeable "Grand Narrative Book".
Ouyang Ruiyang is a "rift repair apprentice" - his job is to sneak into the logical gaps in the story and repair the causal gaps.
But he hides a secret of the academy: he can hear the deepest "narrative echo" in anyone's heart - not only true and false, but also the "character fate line" given to the other person in the story.
One day, while repairing a small crack, he heard a heartbeat from the original manuscript of "The Grand Narrative":
"The prophecy has been tampered with. The real chosen one is not the hero."
In order to avoid being admitted to the academy, he must simultaneously deceive the hero, the mentor, the abyss, and——
An enemy who could hear his inner secrets.
