Went Through the Wrong Prince's Mansion and Was Targeted by the Crazy Criticizing Regent.

A modern dying girl purchased the book-traveling experience service. She originally wanted to dress up as the heroine of the original book and enjoy the sweet story. However, due to an after-sales binding error, she transformed into Lu Yanchi, the second daughter of the Duke of Zhenguo. She turned out to be a spoiled and vicious female supporting character who died early. She had just failed in her plan to frame the heroine, and accidentally broke into the mad regent's chamber, injured him and escaped, thus starting a hell-level survival start.
