Chuan Shu: I Became a Vicious Male Supporting Character

The male protagonist wore a book and became a villain! The protagonist in other books has super powers, but he is just a vicious supporting actor. Fortunately, he had read some plots, and it seemed that it was not impossible to change his tragic fate. What? Being cannon fodder to set off the male and female protagonists? That's impossible! How do you say that? "I was born to be a mountain, not a stream. I want to stand on the top of a mountain and look down at the mediocre ravines. I was born to be a hero, not a must. I stand on the shoulders of great men and look down on humble cowards!" I don't care who you are! I just want to be on the opposite side of the male lead! I just want to compete with the male protagonist for a woman! Ahem, keep a low profile... Actually, I don't want to either, it's just that my father-in-law gave me too much. Later, he used his knowledge, talent, ability and... System to establish his own kingdom in the barbaric era. This novel and its characters are purely fictitious.
