After the "death" of Qin Shihuang Yingzheng in the Sand Dune Palace, his consciousness awakened in modern times across two thousand years, and at the same time, the historical torrent of the late Qin and early Han Dynasties rolled forward. Two "rising from the bottom" stories unfold in parallel - the ancient Liu Bang's journey from pavilion chief to founding emperor, and the modern Ying Zheng's counterattack from courier to technology giant. The two timelines finally intersect through the concept of "time machine" to explore the themes of power, civilization and eternity.
