Be Careful You Are Cannon Fodder

Wen Xian traveled through time and entered a book she wrote. Unfinished book. She is a cannon fodder who burps after three minutes of appearance. She worked hard to disrupt the plot and try to live. Then died. Wen Xian was reborn. She thought she could survive by hugging Master's thick legs. Master cultivates the ruthless way. She died again. Second rebirth. Wen Xian finally thought that she was not the protagonist of this world. But she—— It's the author! Sorry, this world is in my hands! The male protagonist and the female protagonist have a ruthless master? Please give in! You've been cannon fodder! ———————————————— PS: There is a pseudo-quick travel plot inside. A big story within a small story. PPS: The heroine is stupid and has a stupid brain, and the author is also stupid and has an even bigger brain. I look forward to a little brother and sister who can save the author's IQ. Thank you!
