Sorry for replying one more time but I gotta explain this Oryx doesn't die by terrestrial bullets what he dies by is us cutting him off from feeding the worm inside him and thus it devours him( aka his chest looking like it got eaten with a gaping hole there) note in order to do this one would need to defeat every boss in Kings fall as well as use the powers of the travelers light so that's why Goku can't beat oryx
