"History is alive and it's hungry."
In this world, history is no longer a static text, but an "entity" that is constantly creeping and swallowing reality. Antiques are the excrement of history, and relics are the wounds of history.
The protagonist Shen Ji, as a cultural relic restorer with "obsessive-compulsive disorder", his job is not to glue porcelain, but to "repair" those distorted and mutated historical fragments back to their original appearance - even if that means using a scalpel to remove excess "historical accretion tissue".
The timeline is shattered. When you walk out of your house, turn left and you may enter an alley from 20 years ago; if you turn right, you may fall into the execution ground of the Ming Dynasty.
Three iron laws:
Don't try to understand unknown history books by "reading", the words will be parasitic on the cerebral cortex.
If you see two people who look the same, kill the one with no shadow, or the one with a red shadow.
The restorer is a madman, but only a madman can save the world.
