A single map holds every secret under heaven.
Across the vast lands of the Great Yong, maps marking mountain passes and cities conceal secrets that could upend the imperial court.
Ye Zhaoning, the last survivor of the Ye family, possesses exceptional surveying skills, but her entire family was massacred.
Three years later, she enters the martial world with half of a damaged map. Together with Xiao Yan, the irreverent third prince, and Lin Wan, a secret guard burdened by a blood feud, she forms a mysterious investigation team, brought together by the map.
From the deserts of the northern frontier to the waterways of Jiangnan, every case, from smuggling on the canals to corruption in the salt and iron trade, bears the map's sinister shadow.
Ye Zhaoning wields her brush like a blade and uses maps to plan her moves, unpicking the truth amid layers of danger.
She knows the map her father left behind charts more than mountains and rivers. It also conceals a deadly secret.
The northern tribes covet it, dark schemes stir in the southern borderlands, and powerful officials in the court watch hungrily. With all these forces converging, can Ye Zhaoning protect the map's secrets? And when the truth comes to light, how will she turn the tables?
