Gunfire, curses, and the continuous rocking of the ship.
The atmosphere aboard the ship grew tense, as the crew fiercely battled against the half-human, half-fish deep divers.
In response to the crew's gunfire attack, the deep divers retaliated with various strange weapons made of coral, most of which were melee weapons, but some were ranged.
"Whoosh—" A long spear attached to a rope shot forth, stabbing a sailor in the stomach, the rope taut, dragging the screaming sailor's exposed intestines toward them.
The next second, the rope slackened, and the deep diver pulling the rope had its head blown off by Charles with a direct gunshot.
Although the deep divers looked terrifying, compared to other indigenous people Charles had encountered on different islands, they were not very strong; for a time, the battle was evenly matched.
