Wen Zhao has lived for more than a thousand years, and his biggest wish is not to ascend, but to retire.
During the day, she is a taciturn outsourced data clerk at the Yunling City Museum, checking pictures, checking numbers, and clocking in on time; at night, she is a specially appointed handler for the secret cultural protection agency "Jiu Ku", specializing in dealing with abnormal cultural relics that cannot be known to ordinary people.
Until a thunder-patterned bronze mirror that had been missing for 79 years called out her name on the live broadcast, and the sleeping strange objects began to return to the world one after another: the bronze mirror looking for its old owner, the wind lantern that could never be extinguished, the bronze bell that took away the testimony...
They did not appear accidentally, but were "returned" in a planned way through legal channels.
When ancient rules invaded modern cities again, Wen Zhao had to track down the truth with a group of human colleagues with their own strengths. But she gradually discovered that what the other party really wanted to awaken might not only be these ancient artifacts, but also an old covenant that everyone had deliberately forgotten.
