Shen Zhuo, a national infrastructure engineer, transformed into a newlywed county princess who was abandoned by her family and married to the border. Faced with the barren and desolate fiefdom and the "sick and dying" husband, she laid out the plans, burned bricks, built roads, and launched commerce, vowing to build the barren land into a prosperous and strong city. When the enemy's iron cavalry approached the city, she stood on the towering city wall she designed and saw the husband of the county prince who was rumored to be dying. He was wearing black armor and taking the enemy general's head among the thousands of troops. He came back from bathing in blood, wiped the dust from her cheeks, and asked with a low voice: "Does the world you want to start painting from here?"
