Is It Really Reasonable for a Person to Be a Villain in a Book Like This?

I am Xu Ran. I accidentally traveled into the book and became the main villain in the book. I also activated the "Villain Rationalization" system. Can you become an immortal as long as you do "reasonable" things? So what are you waiting for? I can't wait. "The protagonist's opportunity? Take it!" "The protagonist's skill? Steal it!" "The protagonist's divine sword? Steal it!" "The protagonist's woman?..." "Hold*, why are there so many?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
