How Do I Spend the Billions of Dollars in Wealth My Father Left Me?

The heroine was an advertising designer who loved money as much as her life. She died suddenly after working overtime for half a month, and her soul traveled to the daughter of the richest man in the Song Dynasty, Wang, whose surname was Wang, Li Qinghe. As the richest man in the Song Dynasty, he had no money in his pocket. He only owned his family property, fields, village, and grassland. The key is that most of his family property was at a loss. Even if he didn't make money, he would still lose money at every turn. Traveling through the past started a series of stories about saving the family property. There are no superpowers, no cheats, and no CP. It all depends on the heroine working hard to protect the family business (It's not easy to code. If you don't like it, just throw it away. Be gentle...)
