This epic time-travel novel takes Qin Shihuang's time traveling through modern times and Liu Bang's founding of the Han Dynasty as its dual main lines. It displays two completely different emperors' survival wisdom through parallel narratives. The ancient line shows the change of power and the rise of dynasties, while the modern line depicts the transformation and awakening of an emperor through the ages in civilian life. The two clues echo each other thematically, and finally achieve a dramatic intersection through the time machine.
