Hidden within the red walls of the Forbidden City are "unarchived cracks in time and space." Every hour, some cultural relics will activate "Copies of Rules and Ghost Stories," which are derived from palace secrets and folklore of the Ming and Qing Dynasties (such as "The Shadow Count on the Nine Dragon Wall" and "The Curse of the Embroidered Shoes in the Imperial Garden"). If the rules are violated, the restorer will be sucked into the historical time and space corresponding to the cultural relics, and will forever become a "living exhibit."
Shen Qinghe (26 years old, New Generation Cultural Relics Restorer of the Forbidden City)
On the surface, he appears to be a taciturn technical geek, but in fact he is a descendant of the "Mausoleum Guards". He is born with the ability to see the "lines of resentment" on cultural relics and has a special intuition for breaking rules.
In order to find the master who has been missing for 3 years (the previous generation of tomb keeper), he took the initiative to take over the "night shift restoration task" of the Forbidden City and got involved in the weird rules.
