996 Civil engineering dog Jian Ning, when he opened his eyes, he was in an ancient mass grave. Good news: She wore it. Bad news: Dressed as a weak, penniless woman who was abandoned by her family, she started off badly, and her survival depended on running. The worse news is that there are frequent wars here, and the people are in dire straits. The thatched houses they live in are leaking from all sides, the only stone bridge collapses when stepped on, the official road is full of mud pits, and it turns into a swamp when it rains.

Jian Ning: "Wait a minute, I'm selling myself even though it's not written in the contract!" By accident, she seemed to have turned a evil prince into a contractor?
