Lin Xiaoyu, a recent graduate, accidentally inherited a private museum that was on the verge of bankruptcy, only to find that the exhibits in the museum "came alive" every night. In order to maintain operations, she recruited "special employees" with a monthly salary of 2,500, and attracted historical celebrities to compete for the job - a henpecked poet, a social horror inventor, a foodie concubine, and a humanistic writer. They all took up the post one after another. They used the skills of their respective eras to get involved in the modern workplace, triggering a series of hilarious incidents and crises, and ultimately jointly guarding this wonderful place that connects ancient and modern times.
