I Farm in Military School and Dominate the Galaxy

Agricultural student Lin Xiaohe has crossed over, finding herself as a young girl on a trash planet in the interstellar era, about to drop out of school.
With a disabled father, a seriously ill mother, elderly grandparents, a mentally ill older brother, and a mute older sister, the whole family depends on her!
Thrown into an exam hall right after transmigrating, Lin Xiaohe couldn’t answer any of the questions—except for the final, additional agricultural science question.
“Lin Xiaoqiao is in luck! She actually got admitted to the Federal Central Military Academy!”
“What’s her major? Mecha or Engineering?”
“The College of Agriculture!”
“So after graduation, she’ll still be a farmer.”
Carrying her backpack, Lin Xiaoqiao vowed to her tearful family, “Grandpa, Grandma, Mom, Dad, Big Brother, Second Sister, don’t worry! I promise to farm more, fight less, and keep a low profile whenever possible!”
