I'm a Beta Tester in the Transmigrate-Into-a-Book System

[Notice: Starting June 8, the novel will go premium after chapter 30. If you've already read those chapters, remember you don't need to buy them!] As a beta tester for a transmigration-into-a-book System, Yan Qing transmigrates into the character Yan Daoqing. All she has to do is follow the plot to complete her mission. All she wants is to do the mission, do the mission, do the mission, and clock out! Unfortunately, this nouveau riche young woman, disliked by everyone in Yedu, is in love with Xie Sanlang, the peerlessly elegant prince of Duan's household. Everyone praises his noble, moonlit demeanor, but only Yan Qing knows he's rotten inside. Still, she has to pretend to admire him. Xie Yu: I'm in a bad mood. I want a copy of Wang Xizhi's Peaceful Greeting, written in Lin-style script. Yan Daoqing: Your delivery is on its way. Please sign for it! Xie Yu: I want to see fireworks. Yan Daoqing: I'll have them set up tonight! Until one day, Xie Yu asks her in a hoarse voice, his face pale: “Do you still have feelings for me?” Female lead: I'm just an emotionless mission machine... Coming soon: On the Self-Cultivation of a Substitute. Hope you'll add it to your collection! The first time Xiang Ling saw Ruan Zhao was in the bitter winter of Jingye Year One. He had led a million cavalry to storm the royal city and avenge the humiliation of his years as a hostage. On a tall horse, the bloodstained young man looked dark and sullen, like a god of death incarnate. She stood barefoot on the ground, kneeling with the palace attendants as they awaited their fate. Xiang Ling's gaze swept over them, then stopped on her face. He pointed at her. “You. Come here.” From that day on, she became the springtime beauty he would never forget. * Ruan Zhao transmigrates as a doomed NPC from the original story, an illegitimate daughter raised in the wilderness. Her useless father loses his kingdom and gives her to a prince of the enemy nation. Ruan Yuanyuan knows how to play along. After learning she's a substitute for Ruan Xi, the original heroine, she practices day and night to make every frown and smile look as much like the real thing as possible, all for the sake of her escape plan. A person shouldn't bow down for a mere three dou of rice, but one dou is enough for her. But before the plan is even a third complete, the real Ruan Xi returns. She's the heroine of the original story, the one who has all the world's love. Ruan Yuanyuan is nothing but an awkward replacement. Ruan Yuanyuan quickly packs her things and decides to start her escape plan early. From then on, the world will be hers to roam as she pleases. Years later, Ruan Yuanyuan meets Xiang Ling again outside the capital. The young man who was once aloof and above the common world now begs her desperately: “Zhaozhao, you've always been the one I've loved. Please, don't leave me.” Ruan Yuanyuan's inner thoughts: Hmph. What a fickle scumbag. * A resilient female lead who knows when to bend and when to stand firm. She can eat and sleep, but she'll never fall for the male lead. Content warnings: 1. The female lead does not end up with the male lead. She gets the life she wants, and that's her happy ending. 2. The original heroine isn't vilified. She is also saved and leaves an unhealthy relationship. Theme: An emotionless mission machine
