Civil War in America

Transmigrated into the body of a homeless drifter at the bottom of American society, the protagonist finds himself bound to a Dungeon Adventurer System. This unique interface allows him to interact with hidden supernatural entities within the modern world. By discovering the corpse of a retired Demon Knight, he acquires the M4A1 Mastery skill. Saving a fallen Dark Elf on the streets grants him experience points, while encountering a wandering retired Dark Dragon Rider provides the opportunity to guide this powerful being toward a mysterious Eastern nation. As his actions draw the attention of the Dark Court, he becomes a wanted man, yet simultaneously gains significant prestige. Unlocking the achievement "The Only Transcendent," he stands alone as a supernatural force in a mundane world. With power rising and tensions mounting, the stage is set for chaos. Burn, America!
