The Supernatural Recovery Bureau: Grave Robbing in the Gods' Game

A small-time dealer in Panjiayuan picks up a Warring States bronze mirror late one night, then discovers that his sister has been eaten by a thousand-year-old fox spirit, his parents are trapped in 1942, and aliens are treating all of human history like a game they can rewrite. Now he has 24 hours to decide: run for it, or fight these filthy things to the bitter end.
