Lan Zhi, a modern young engineer, accidentally traveled to the end of the Qin Dynasty in parallel time and space, and became the son of a criminal who was implicated and exiled to northern Xinjiang because of his father's "irrelevant discussion of government affairs." The beginning is hell: trapped in a bitter cold frontier, with a humble status like an ant, and may die at any time from hard labor, severe cold, or Huns raids. What's even more fatal is that he is keenly aware that this seemingly powerful "Great Qin" is seriously ill - although the First Emperor has passed away, the harsh punishments, abuse of people's power, ideological confinement and other institutional shortcomings he left behind are pushing the empire to the brink of collapse. The powerful minister Zhao Gao controls the government internally, and the remnants of the Six Kingdoms outside are ready to take action, making the people at the bottom miserable.
