[Marriage First, Love Later + Infrastructure Building + Farming]
Shen Li transmigrates to ancient times, where her uncle forcibly takes the family property and tries to make her become County Magistrate Liu's concubine.
Shen Li unlocks the Provincial Prosperity System. To return to the modern era, she must grow Huanghua County's population from its starting point of five hundred to one million.
To get home and have a legitimate reason to run businesses, improve Huanghua County's infrastructure, and attract newcomers, Shen Li begins pretending to marry Xiao Yan.
Thanks to their joint efforts, more and more people return to Huanghua County, and local businesses even begin to do better than those in the capital.
As Shen Li and Xiao Yan build their ventures together, they support each other and gradually fall in love.
Then Xiao Yan's hidden identity is exposed, and Shen Li chooses to distance herself from him.
Xiao Yan: "No. You're already my wife, and that's a fact. No matter how you try to get away, I'll bring you back."
Shen Li: "Xiao Yan, if you're the Crown Prince, why didn't you tell me?" (In her thoughts: He made me stress over having no money for infrastructure every day.)
Xiao Yan: "But I'm yours. Everything I have is yours."
