After I Transmigrated into a Book as a Baby, I Disguised Myself as a Man and Became a Powerful Official

【Transmigrate into a book + doted on by everyone + System + disguised as a man】 Gu Zhiyin received a mysterious package and transmigrated into an autobiography written by someone else. A pitiful girl disguised as a boy, she inexplicably received a System mission: help the pitiful Third Prince become an emperor for the ages. Well, this was going to be a tough one! So she had no choice but to work hard to get close to the Third Prince. Unfortunately, she wanted to keep her secret identity intact and serve as a loyal subject, but what she didn't expect was that the prince she was supposed to win over would be even more forward than she was! Still, becoming an emperor for the ages wasn't easy. But this Third Prince was lazier than a couch potato. He was completely useless! Gu Zhiyin could only give the whip in her little hand a flick. What was so hard about making life better for the people? She'd do it! Bonus scene: After successfully becoming a young prince's study companion and staying by Jun Moxuan's side, Gu Zhiyin frowned. How was she supposed to tell whether Jun Moxuan liked her? “Ding! Host has successfully activated the affection-level detection program. Jun Moxuan's current affection level: 03 (out of 100).” Gu Zhiyin: … That affection score was in the single digits! She really hadn't expected that. She poked around in the System and saw that the feature unlocked once the score went above 1, which left her even more speechless. So her affection score had been below 1 this whole time? How annoying! She pouted, glanced at the cold-faced Jun Moxuan, and deliberately put on a sweet voice as she prepared to leave. “Third Prince, your servant takes his leave!” Jun Moxuan grabbed Gu Zhiyin. As the System warned that her affection level was dropping, he said in a low voice, “Why don't you call me big brother?” Gu Zhiyin stared at him, wide-eyed. “Huh? That's it?”
