I Transmigrated into a Book for a Quiet Life, So Why Did I Awaken an Empress's Destiny?

[Transmigrate into a book + fight for supremacy + turbulent times + strong female lead + no romance + nation-building] She transmigrated into the role of a minor young lady in a male-oriented novel about contending for supremacy. With chaos looming, the laid-back Lu Hanyue just wanted to cling to a powerful patron and lie flat, taking it easy. But it seemed she was destined to bring bad luck to anyone who supported her. She took an arrow meant for the original male lead. It missed her and pierced him through the heart instead. She traveled far north to the grasslands to help the Heaven-Chosen Khan ascend the throne, only for him to get carried away as soon as he took power. He was shot in the head by a stray arrow during a campaign and died on the spot. She then headed south to join the Chosen One, only to discover he was a bloodthirsty lunatic. He had none of the qualities of a powerful patron. All three patrons were done for. Despondent, she just wanted to find a remote mountain hollow and completely give up. But just then, chaos broke out. The villagers she had once saved and her former subordinates gathered beneath her banner to discuss what to do! “Miss, the realm is in chaos. Please show us a way to survive!” “Miss is wise and mighty, virtuous and respected, and cares deeply for the people. If she doesn’t take the throne, who can?” “Your servants pay their respects to Your Majesty!” Lu Hanyue blinked. “Huh? You mean me?” Before she could refuse, they all pushed her onto the throne. Three years later, memorials were piled high as a mountain in the Hall of Supreme Harmony. Lu Hanyue fell silent for a long moment, then finally realized the truth. “The powerful patron I spent my whole life looking for... was me all along.” The next second, her smile vanished completely. “If I’d known I’d have to review memorials every day, I’d have been better off letting that arrow kill me!” “You’ve... made things so hard for me!”
