Extra Tale

i got hit by truck as a result i got reincarnated as a extra in the novel that i read However this is not a regular novel this novel is called 'the legend of sword saint' and the world ended in the end of the novel 'shit...iam screw' in order to make sure i didn't messed up the story i would lay low and i would stay as far as possible from the character in the novel probably.... (Please noted that i am still new and this is my first time writing novel.english is not my first language. The Image book cover is not owned by me i am not the one who draw the cover)
