Adapted from the movie version of "Myth". Yi Xiaochuan (Hu Ge), a boy born in the 1980s, came to the archaeological site where his father worked and was accidentally involved in a struggle for treasure. He and his friend Gao Yao (Zhang Shi) traveled to the Qin Dynasty more than 2,200 years ago. Xiaochuan met Xiang Yu (Tan Kai) and Liu Bang (Li Yixiang) successively, and then became brothers with them. He was mistakenly recognized as Meng Yi by the general Meng Tian (Ding Zijun). Xiaochuan was admired by many women because of his modern ghost and funny. Among them were the two sisters Lu Zhi (Chen Zihan) and Lu Su (Jin Sha), but Xiaochuan only had Princess Tuan Yu Shu (Bai Bing) in his heart. Gao Yao became the treacherous minister Zhao Gao and recognized Xiaoyue, a palace maid who looked like his sister Gao Lan (Zhang Meng), as his sister. Xiaochuan's 27th girlfriend Gao Lan fell in love with Xiaochuan's brother Yi Dachuan (Ren Quan) when they were looking for their whereabouts. As the Qin Kingdom is about to fall, can Xiaochuan and Princess Yushu stay together forever? And where will Gao Yao go?
