Three years after the new emperor ascended the throne, he gave flowers and selected concubines six times, but none of the six beauties survived the seventh day. Therefore, the harem is still empty of concubines. There are rumors outside the palace that there is a set of life-preserving rules hidden deep in the palace, but no one knows the content, and the rumors circulated are either true or false. In order to find her sister who was forgotten by everyone after entering the palace twelve years ago, Xie Mingyi participated in the draft. After entering the palace, she, Emperor Xiao Zhi, female officials, and palace officials searched for common ground among anomalies, verified rumors, and pieced together rules. It wasn't until the seventh flower fell into her hands that she discovered: the real danger is not breaking the rules, but someone taking advantage of everyone's trust in the rules. She only has seven days to find out what the first six women saw and to find the chess player hidden deep in the harem.
