Modern young man Qin Tian discovers that his home toilet can travel through time to the Dasheng Dynasty, where he meets Xiao Yuer, a foodie imperial concubine. Xiao Yuer comes every night to mooch fried chicken, and even brings her best friend Meng Fangyi along. Qin Tian wins over Meng Fangyi with his phone-based Go skills and asks her to help him deal with his mother’s blind date banquet. Subsequently, more imperial concubines like Dieying and the plump Empress Yun Jinyi arrive one after another. Qin Tian captivates them with cosmetics and modern life. The plump Empress drops her pretense because of Qin Tian’s sincerity, and all the concubines join forces to help him get through tough times. In the end, Qin Tian reaches an agreement with the emperor: in exchange for 50 million worth of arms, he gains the freedom of the concubines. The five of them start living together in modern times, and Qin Tian achieves success in both his career and love.
