From the webnovel series "The Flash: Please Kill Me," this is the story of Adam Stiels, a Flash enthusiast who is transported into the Arrowverse with an "Immortal System" that grants him new skills from whoever kills him. Driven by a morbid need to die repeatedly to upgrade his powers, Adam joins Team Flash, using his sarcastic wit and future knowledge to navigate the dangerous world, all while pursuing the icy heart of Killer Frost and forging a strong friendship with Supergirl.
Awful. Just a bunch of nonsense put together. He just knows things and no one is questioning that. Give him a better back story.
Aside from the rather mediocre story. I saw you don't like negative reviews? As a writer negative reviews should be what you need to improve, the fact you use AI to help you is proof of that. You're on training wheels and you want people to treat you better than they treat good writers?
