[Western Crossover] Earth's Last Administrator

Lin Mo initially thought he'd transmigrated into a parallel world of superheroes. It had a certain genius playboy entrepreneur, but no Iron Man; a war hero and spiritual leader, but no Captain America; and a Brucey baby, but no Gotham vigilante. Then one day, the System informed him that he was the last Man in Black on Earth, and that he'd erased the superheroes' memories. ...As well as his own. And Earth would be invaded in six months, with no protectors left to defend it. His current mission was to seek out the superheroes and restore their memories. First day on the job: That Iron Man blasted him with a repulsor. Second day on the job: That Captain America threw him over his shoulder. Third day on the job: That Dark Knight stabbed him with a little dart. Lin Mo: ...Saving the world is way too hard! System: Please keep up the good work, Administrator. There are still 156 superheroes on the memory-restoration list. Lin Mo: ...Was I crazy or something? Theme: Even without superpowers, some people will still choose to become heroes.
