Li Wei, a modern cartography expert, traveled through time and became a draftsman apprentice who was about to be framed and executed during the Tianbao period of the Tang Dynasty.
In order to survive, he was forced to dance on the tip of a knife and pretend to be a member of the "Hedong Pei Family", a top geography family.
Relying on modern geographical thinking, he deconstructed ancient maps and uncovered fatal systematic tampering in frontier maps, thereby becoming involved in a treacherous political secret war.
Under the prosperous times, there are turbulent undercurrents. On the map, every mistake and omission is a murderous opportunity; outside the map, every survey is related to the fate of the country.
See how the protagonist uses accurate maps as a blade to redraw the world structure and find his own way of life in the cracks between clans, powerful ministers and foreign races.
