This is a paper-cut animation. 　　 Sanmianren, Nu'an, and Dailong arrive at a remote island by canoe. Ignoring the island spider's warning—"Never touch that blue bone, or the island will split apart"—they reach for the blue bone. Suddenly, the bone transforms into a fireball. A flash of light erupts, mountains crumble, and the ground splits open, plunging them into a deep, dark abyss.
