Liu Zhiyuan was transformed into cannon fodder in the book, and was dragged out and killed by the tyrant Xiao Yu at the beginning. In a critical moment, she activated the "load and restart" system. Die once, rewind once. The tyrant slashed her eighteen times in a row, but she was resurrected with full health every time, making Xiao Yu collapse on the spot. She was originally thought to be a loser with a golden finger, but she relied on the "infinite file reading" to operate all the way. She beat the queen mother violently, outsmarted powerful officials, developed gunpowder, and helped her husband put down a rebellion. The tyrant changed from "swearing to kill her" to "not marrying her", and even dismissed her harem and learned the "secrets of doting on his wife". But the plot deviated and the system collapsed. She paid the price of staying in the book forever in exchange for staying with her true love life and death.
