Civilian Surveyor

Era background: The fictional dynasty "Dayong", the tenth year of Emperor Yongjing's reign. On the surface, the sea is clear and the rivers are clear, but in fact, water transportation from north to south is blocked, border maps frequently make mistakes, and there are foreshadowings of civil strife.​ Core occupation: The protagonist Shen Yan is a "civilian surveyor" who is good at ancient surveying, map drawing and terrain surveying. He was expelled from the master because he refused to change Feng Shui for the powerful. He makes a living by drawing folk maps and repairing old maps. His left eye can identify the secret marks on the map through special pupil skills (trained later).​ The core suspense: A batch of royal maps marked with "forbidden areas" were stolen one after another, and the officials and painters holding the maps died mysteriously one after another. The deceased were holding a piece of human bone fragment engraved with the map coordinates in their hands.​
