Building Infrastructure from Scratch in Ancient Times

[Three updates a week, always at six in the evening. An everyday-life story!] A modern only daughter transmigrates into the past as a poor, pitiful girl? Her father is a gambler, her mother is a pushover, and now she's going to be sold as a child bride? She builds up a fortune herself, only for people to try to claim it all because she's a woman? Barbarians invade, the emperor flees south, and he still has the nerve to raise taxes and demand money and women? Xu Zheng says, come and try me if you've got the guts! Round one: The awful relatives are beyond saving. They used my money to build their house, so I'll just tear it down. Round two: Divide up all that money that's nothing but an empty shell. I'll come back under a new identity and call you all out one by one. Round three: I don't recognize this emperor anymore. If those brats dare come looking for trouble, they'll get on their knees and call me Dad. Round... that's it. Player "Xu Zheng" has unlocked the unique achievement: "One life at the start, one nation at the end." Xu Zheng: I told you to come try me if you had the guts. Why wouldn't you listen? Everyone: ... Cute points (tearjerker points): The heroine's name is Xu Zheng, though she'll change it later. Her natural strength is half a golden finger. She wins the land with real swords and guns. She loves peace, doesn't have children, and isn't a pushover. She gets revenge and slaps people in the face on the spot (even the most frustrating conflict won't last more than two chapters)! Emphasis: There is a one-on-one romance! The next relationship begins only after the previous one ends! No children! She goes to the grave alone! There is a one-on-one romance!
