I Became a Tyrant Princess and Took Out N Villains

When Gu Zhao transmigrated, the original owner of her body was taking advantage of the beautiful, strong, and tragic general beneath her. She hesitated. To stay in character, should she enjoy herself first? Oh! A palace maid came to report that demons were besieging the city. No need to agonize over it now. The demons are besieging the city. What should she do? Luckily, the System gave her a golden finger: she could increase her cultivation by spending her life force. While everyone else paid to level up, she paid with her life. Fortunately, she could spend the demons' lives instead. (The female lead has an official pairing, but it hasn't been decided yet.) Theme: Exorcising demons and vanquishing evil is the right path, and the farther you go, the broader it becomes.
