Tu Cha transmigrates into a book as the cannon-fodder Ninth Princess. Her birth mother died early, and she was abandoned in the Cold Palace, where she will freeze to death in seven days. The female protagonist impersonates her identity as the child of an emperor with no heirs and becomes the beloved of the entire dynasty. Tu Cha uses her cheat system to earn lifespan rewards and empties her scumbag father's private treasury to amass wealth. There is no sisterly affection here, and she verbally tears her rivals apart. When the female protagonist finally arrives, Tu Cha will simply grab her gold and silver and run!
