The sudden appearance of the System notification and announcement made it clear that what the Island Master had said about Swordsman Island soon facing destruction was true, and he wasn't joking!
After hearing the System announcement and notification, the players, who had already each gained something, were naturally eager to leave, but the NPCs were doubtful and undecided.
In fact, most people were still greedy for the martial arts secrets on the stone walls, preferring the risk of dying over leaving right away.
And if NPCs didn't leave, of course, the players couldn't either.
Even though ships were docked at the shore, navigating them was no trivial matter. Among the players present, not a single one had learned any skills related to navigation; even if they were given ships, they wouldn't be able to sail them.
