Did the female villain finally defeat the male protagonist in the fantasy novel?

"At the finale, the female antagonist wants to kill me!" This book was an Oriental fantasy novel. It was about a failed author, Gu Jin Nian, who was writing his own novel when he was suddenly interrupted by a woman in ancient clothes, Yue Yingchan. Later, in order to avoid Yue Yingchan's revenge, he changed the plot of the novel and finally added a female villain boss. I hope you like this fairy's recommendation. Muah ~😗
