Reborn as the Empress of a Fallen Kingdom, I Use Force to Take Over the Harem

In an apocalypse overrun by zombies, Shen Yuan, a black belt in taekwondo, was starved to death. To her surprise, she didn't actually die. Instead, she transmigrated into a book aimed at male readers, becoming the empress with the same name, whose country is destined to fall in just a few months. In the book, she also has the most tragic fate of any supporting character. Having barely managed to survive, she has no intention of dying. If the country is doomed because the treasury is empty and there is no money, what if the treasury were well stocked instead? The consorts in the palace have nothing to do anyway, so she rallies everyone to put their talents to use: the embroiderers embroider, the rouge-makers make rouge, and they sell it all outside the palace. Before long, whenever the concubines in the harem hear that the emperor wants one of them to attend him, they all have the same answer: “No, no, no, I don't have time. I have work to finish, and I'm about to earn my full-attendance bonus.” The emperor wails, “How did my harem become Shen Yuan's harem?”
