What?! After I Transmigrated into a Book and Tried to Usurp the Throne, How Did the Tyrant Find Out?

[Raising a child + adored by everyone + mind reading + transmigrate into a book + 1v1] Xie Shijin never expected that transmigrating into a book, of all trendy things, would happen to her! What does it feel like to become the vicious supporting female character in a beloved-by-everyone story, living in the Cold Palace and hated by everyone? Xie Shijin's answer: What are you waiting for? Run! She looked down, only to realize what a shame: she was just five years old! A five-year-old little squirt living in the Cold Palace could barely get enough to eat or stay warm. How was she supposed to run away? Don't panic! When it comes to a fight, it isn't about what you want, it's about what we've got! As the tyrant's youngest daughter, she was born into his disfavor and banished to the Cold Palace. Her birth mother was nowhere to be found, and the servants bullied her. A truly disastrous start! But! She was a princess! She had a claim to the throne! She was going to usurp it! The male and female leads could all step aside. Nothing mattered more than her grand plan to become empress! Step one to becoming empress: throw tantrums, roll around, act cute, and cling to the tyrant's leg! Step two: win the hearts of the civil and military officials! Put her professional skills to use and get modern technology rolling! Gunpowder! Bombs! Paper, ink, brushes, and inkstones! She'd blow the minds of everyone in the book's ancient world! Somehow, the tyrant grew gentler and gentler, her Crown Prince brother warmer and warmer, and the book's two biggest villains both turned into doting fathers and overprotective brothers! She snatched all the female lead's opportunities, and the System let out a piercing shriek! Step three to becoming empress: secretly trip up the tyrant! That's how the struggle for the throne has always worked! But... can someone tell her why the tyrant dad can pinpoint every single move she makes? What the hell! He can hear her thoughts!
