Traveling Through the Book to Save the Villain

I accidentally traveled through the book. Not only did I travel through the book, but I was also accidentally bound to the system. The system asked me to save the villain. When I heard this mission, I was stunned. What is a villain? A villain can kill anyone for the one he loves. This is a villain. Let me save him. Who will save me? Will this rescue save me? "The host will be punished if he doesn't do it." Listening to the system's words, I can't wait to throw it out of this dog system... This novel and its characters are purely fictitious.
