After I Transmigrated into a Book, I Became the Empress

Jin Yanqiu is transported to an ancient era of turmoil, reminiscent of the Three Kingdoms and Wei-Jin periods, and becomes the daughter of an official. She lives in an age when she can have nothing she wants and the emperor is a madman, trembling through life until she turns sixteen. Then a System suddenly binds itself to her and orders her to win over the male lead. It says that only by winning him over and helping him unite the country can she save the world. Yanqiu refuses. "I'm not interested in a murderous, unhinged male lead like that." The little System wails and throws a tantrum. "But if you don't win over the male lead and help him unite the country, this nation will descend into two hundred years of civil war. Nine out of every ten people will die, and you and your family won't survive either..." Jin Yanqiu shudders and sits bolt upright. "Fine, I'll win him over. What kind of golden finger can you give me?" The little System curls into a ball, embarrassed. "S-Sorry, I'm useless. I can't give you a spiritual spring dimension, make you beautiful, or provide all kinds of miraculous medicines..." Jin Yanqiu lies back down, deciding she might as well wait to die. The little System speaks timidly. "I can only smuggle over food from the world you used to live in, food that was thrown away or wasted, and give it to you. Sob, I'm sorry I'm so useless..." "What did you say?!" Jin Yanqiu instantly sits up and looks at the System's interface. Rice, flour, sprouted potatoes, candy and biscuits nearing their expiration date... More than one billion tons of food are wasted on Earth every year, amounting to one-fifth of all food available to consumers. And now it's all hers?! "System, can we talk? What if I don't win over the male lead and just save the world instead?" One day, the sun shines brightly beneath a clear blue sky. Jin Yanqiu stands atop the city wall, admiring the scenery in the distance, when her great general, Mu Guang, suddenly drapes a dragon robe over her shoulders. "My lord, it's getting cold. Allow me to put another layer on you." Reader's Guide: 1. The setting draws inspiration from the Three Kingdoms and Wei-Jin periods, but isn't historically rigorous. The main story is about the heroine having an unlimited supply of food and recruiting soldiers and horses to conquer the land (though she doesn't do much conquering). 2. The male lead is not the original novel's male lead. The original male lead is the heroine's rival. 3. There will be many scenes where the heroine gives people food, and they immediately bow down and worship her as a deity. 4. There will be extensive descriptions of supporting characters. Theme: Helping others is helping yourself
