In 1215, under the rule of its fifth emperor, the Xi Dynasty entered its golden age. The dynasty's founder, Emperor Xitai, had originally been an ordinary farmer. When he was thirty, he suddenly launched a coup and established the Xi Dynasty. He had once lived in Xishui Village at the foot of the Tianshan Mountains. It was later renamed Nanxi City, where a vast estate was named Xitian Manor by Emperor Xitai himself. A snake immortal named Helian Heichi lives there. Bai Qianyan, who lives in the 21st century and has reached the age of thirty, never imagined she would become part of this history.
