Defeating Dungeons via Copy Paste!

Han-Jun is the weakest hunter alive. While others wield powerful skills, he’s stuck with a useless copy-paste ability and mocked by everyone around him. Cursed during the Great Calamity, he has only five years left to live… but Han-Jun refuses to give up. When a chance discovery reveals his skill’s hidden potential, everything changes. As he rises through the ranks, a new calamity begins to stir. Time is running out, and Han-Jun may be the world’s last hope—an unlikely hero with a power no one saw coming.
