The Imperial Jade Seal was nourished by the power of common people's thoughts for more than two thousand years. It awakened as a spirit in the 21st century and traveled back to the site of Qin Shihuang's coronation ceremony in 221 BC. As the "immortal seal", it helped the First Emperor reform his internal affairs, care for the six countries, develop workers and peasants, cultivate the prince, and jointly build the immortal Qin Dynasty. The main plot combines the weight of a historical drama with the smoothness of a time-travel novel. It focuses on the heartwarming father-son plot of "Brother Zheng takes care of his baby (Xiling) to govern the country" and the sentiments of family and country where the group struggles.
