Lonely Attack on the Different World (WN) - Chapter 275: part 1

Derek Carter never asked for a System, an apocalypse, or the pressure of being humanity’s so-called “last hope.”He was just trying to survive the daily struggles of being an orphan in Paleview City—dodging bullies, scraping together meals, and lying his way into school. Life was already hard enough.Then, one day, a blue screen pops into his vision:[Warning: The world is doomed. Try not to die.]Yeah, great. Just what he needed—cryptic doomsday messages and no instruction manual.Now, monsters are creeping into the city, reality is unraveling, and Damien’s “legendary” starting stats are barely above zero. The System promises him power, but there's just one tiny problem—he’s never won a fight in his life.Armed with sarcasm, questionable decision-making skills, and the sheer refusal to die, Damien is about to embark on the worst (and possibly last) adventure of his life. Because if the world really is ending… he’s at least going to make it someone else’s problem first.After all, heroes are overrated—survivors get to tell the story.

His fiancée, whom he had never met, had just broken off their engagement. He's then betrayed by his girlfriend and schemed against by her lover.His mother's legacy awakens him. No longer content with mediocrity, he transforms into a dragon overnight.
