Zhang Qiwen and Li Shiyu were originally college students in the history department. They traveled to the Great Xia Dynasty together. Only when they completed the designated tasks side by side could they travel back.
But by some mistake, the time-travel system malfunctioned, and the hosts of the two were swapped. As a result, Zhang Qiwen, a young male tycoon, took over the body of Princess Li Changle of Daxia and used it to roam the harem, while Li Shiyu, a female academic tyrant, time-traveled into the body of Qin Li, the down-and-out son of the famous Daxia general Qin Qiong.
First, they have to find each other in the vast crowd, complete the task of exchanging bodies, and then follow the main mission to leave the legend of the two in the history of Daxia.
