"The moment you touch an old thing, you become the next sacrifice."
Lin Yan, a 26-year-old restorer of ancient books, was dragged into a strange space called "Regional Ruins" because of the half of a Nuo opera mask left behind by her grandmother.

She must use folk customs to solve the puzzle before the countdown to the "cultural node" ends, otherwise she will be assimilated by the realm forever.
