Starting a Shop, I Raised a New Emperor and a Prosperous Age

[Infrastructure construction + Seizing the direct descendants + Marriage first, love later + Strong mutual protection] The abandoned daughter of a prince who traveled through time was stuffed into the "empty east palace" that everyone avoided at the beginning to wait for death? Looking at the prince's palace that was too poor to pay for the money, the desperate situation of seizing the rightful son, and the "sick" prince next to him who was said to not survive the next year, Su Wanqing silently used the business and agricultural knowledge in her mind. No money or food? Then start from a dessert shop! Make incense, open a restaurant, promote farm composting, and establish the first bank in Dayan. When the second prince united with the family and tried to force the prince to depose by cutting off his salary, Su Wanqing backhandedly threw out the account books that made the country extremely wealthy, directly cutting off the economic lifeline of the capital! Everyone suddenly realized that the Dayan Dynasty's money bag had long been firmly held in the palm of this humble princess. Until that day when the army came to the city, the originally weak prince decided the situation with a sword and protected her behind him. The new emperor ascended the throne. Su Wanqing was just about to retire with her banknotes, but was restrained by a man on the throne: "The country is yours, and I am yours too. The queen wants to go on strike. Has she asked about the jade seal in my hand?"
