After the Sword Sect's Eldest Senior Sister Bound the Dragon-Swagger System

Yu Yin transmigrated into a book, becoming the foil to the heroine in a cultivation novel. Not only was she pushed by her biological father into taking a blade for the heroine, she eventually met a tragic end because the heroine fell to demonic cultivation. Yu Yin thought she'd gotten an underdog-to-champion story. But on her very first day as the Blade Sect's senior disciple, her master came running over in tears. "My disciple, the debt collectors are here! Save me!" A massive bill flashed through Yu Yin's mind: Six months ago, her uncle-master, a blade-forging fanatic, bought twenty thousand yuan's worth of blade-forging steel on credit! Last month, her drunken grandmaster bought a hundred thousand yuan's worth of premium liquor on credit! Yesterday, her combative master destroyed the Pill Sect's pharmacy while buying medicine to help her break through, and now owes them five hundred thousand yuan! Yu Yin's vision went black. Just then, a System appeared: [Congratulations, Host, you've been bound to the Dragon Protagonist Development System. This System has already devised a training plan for you. Complete the missions to earn huge rewards... Wait! I bound the wrong person!] Yu Yin's eyes lit up. Rewards meant spirit stones! She promptly swung up her giant blade and threatened it. "Say that again?" The System immediately shouted: [I didn't bind the wrong person! You are the Dragon Protagonist himself!!!] * Step One of the Dragon Protagonist Development Plan: The System declared: [How can a Dragon Protagonist not challenge someone at a higher level? See that Foundation Establishment spirit beast? Get it!] Yu Yin, at the peak of Qi Refining: ... But for the sake of that huge reward, she promptly charged forward with her blade. Blade Sect disciples: "Gasp! Senior Sister is so fierce!" Step Two of the Dragon Protagonist Development Plan: The System said excitedly: [How can a Dragon Protagonist not have a few beautiful confidantes? See that girl being chased? Go get her!] Yu Yin glanced at the reward on the mission screen and swiftly swung her blade! The girl she'd rescued looked at her shyly. "I can never repay you for saving my life..." Yu Yin replied without thinking, "Then give me spirit stones." The girl and the System: "..." Before long, everyone in the cultivation world knew that the Blade Sect's senior disciple was a battle fanatic who loved drawing her blade to help girls in trouble! Even the novel's heroine, after her identity was exposed and she was hunted down, was overjoyed to see Yu Yin. "Senior Sister Yu, save me!" Yu Yin slowly turned her gaze away. "Huh? Did someone say something?" The scumbag father, gravely wounded while protecting the heroine, looked to Yu Yin with one last hope. "Your father was wrong. Save me!" Yu Yin looked at the pursuers. "Brother, mind if I get in a couple of extra cuts?" The heroine and her scumbag father: !!! *Bonus Scene* Everyone knows that sword cultivators and blade cultivators in the cultivation world are famously poor. And blade cultivators aren't as cool as sword cultivators, either, so everyone says blade cultivators will never measure up to sword cultivators. That is, until Yu Yin burst onto the scene, wielding a giant blade with the force to shatter mountains and rivers, and broke the Sword Sect Immortal Lord's life-bound sword while fighting above her level! Everyone (gasping): "Is it too late to switch to being a blade cultivator?!" [Leveling-up story, mildly goofy] Theme: Every step you take should be true to your conscience
