Fantasy: a Shell Gun at the Beginning

Traveling through the fantasy world, you will be rewarded with a shell gun at the beginning. Faced with powerful martial arts, magical skills, and brilliant martial arts... The shell gun is not powerful enough? It's okay, give me some Gatling! Is it enough to fire six thousand rounds of ammunition per minute? Is the opponent's backstage dad here? Don't be a coward! There is nothing that a strategic nuclear missile cannot solve. If so, get two! If that doesn't work, just use missiles to clear the ground! ! This novel and its characters are purely fictitious.
