Modern-day HR manager Jiang Xiaoyu transmigrates into the body of a palace maid in the Cold Palace, doomed to be beaten to death in the very first chapter. On the spot, she gives the supervisor an employee performance review, surviving by relying on a bottom-performer dismissal system. The emperor is short-staffed, so she turns the harem into a workplace: palace maids clock in, consorts get KPIs, and the emperor is the client. The unhinged Eunuch-in-Chief Xiao Wujiao hands her a contract of servitude. "Sign it, and I guarantee you a perfect performance rating." As she reforms the workplace, she also uncovers one explosive secret after another: the empress's substitute, an official's illicit affair, and the princes' true parentage. The Noble Consort wants to manipulate her? She'll have to get past Jiang Xiaoyu's shift schedule first. The court officials go on strike? Jiang Xiaoyu puts them through group interviews and written exams. In the end, she seizes the official seal and promulgates the Harem Labor Law: weekends off, compensatory leave, and full compensation for workplace injuries. Everyone thinks she's about to become empress, but she slips the phoenix seal into a safe. "A working woman's battlefield isn't confined to the harem."
